Pokémon, known in Japan as Pocket Monsters (ポケットモンスター, Poketto Monsutā), is a Japanese anime television series based on the Pokémon video game series published by Nintendo. It began broadcasting on TV Tokyo on April 1, 1997, in association with MediaNet (formerly TV Tokyo MediaNet and Softx) and Shopro, stands for Shogakukan-Shueisha Productions Co., Ltd. (formerly Shogakukan Productions Co., Ltd.). The show's central protagonist is Ash Ketchum, a ten-year-old aspiring "Pokémon master", who participates in competitions involving battles with creatures called Pokémon in the fictional regions of Kanto, the Orange Islands, Johto, Hoenn, Sinnoh, Unova, Kalos, Alola and recently Galar. Ash is usually joined by his electric mouse partner Pikachu and a regularly changing line-up of human friends. These friends are usually Pokémon trainers, such as Misty, Brock, Tracey Sketchit, May, Dawn, Iris, Cilan, Serena, Clemont, Lillie, Kiawe, Mallow, Lana, Sophocles, Goh and Chloe Cerise though some of the friends Ash has adventures with, such as May's brother Max and Clemont's sister Bonnie, are too young to raise and train Pokémon of their own, but Max and Bonnie promised that they will be Pokémon trainers later in the future.
Recurring antagonists of Ash and his friends throughout the show are the frequently comedic, greedy thieves from Team Rocket, made up of the humans Jessie and James, a talking Meowth and later, a Wobbuffet. Ash also competes with a number of recurring rival Pokémon trainers in his journeys, including Gary Oak, Ritchie, Harrison, Morrison, Tyson, Paul, Nando, Conway, Barry, Tobias, Trip, Bianca, Stephan, Cameron, Virgil, Tierno, Trevor, Sawyer, Alain, Gladion, Hau and Bea.

She was one of the four gym leaders of Cerulean City along with her three older sisters, after The Johto arc Misty has been recognised as the Sole Gym Leader of Cerulean City Gym. Her dream is to be the world's greatest "Water Pokémon Master". Misty has a different personality from other companions of Ash. She is not too girly, she was too arrogant to her companions in the beginning and that behaviour slowly began to deteriorate as the series went on. Misty is brave, courageous and accepts the harsh realities of life. She is a constant support to Ash and has saved him from both death and paralysis, even though they both argue over the smallest of matters. During the beginning of the series, she is constantly belittled by her older sisters. At the end of the original series, she takes over the Cerulean Gym. Misty along with Brock has had made a huge impact on both the Franchise and its audience. She plays a key role in making the Pokémon franchise popular it is now. Misty is also known as an occasional performer of the Cerulean City Gym. She is also known as "The Tomboyish Mermaid". Unlike other female companions Misty was the only companion to leave Ash without will.

However, her encounter with Ash and Brock changed that and her love for Pokémon began to grow steadily. She takes interest in Pokémon Contests, entering Contests with Pokémon she raises on her team. After entering contests, she goes on to win many contests. May travels through Hoenn and Kanto with Ash and Brock whilst Ash is competing in the Hoenn League and Battle Frontier, respectively.

As a native of Sinnoh, she often explains certain aspects of the region unfamiliar to both Ash and Brock, and keeps up to date with popular trends like the Pokétch. As she participates and win in more Contests, Dawn gradually becomes more confident in her skills as a Coordinator and regularly trains with her Pokémon before every contest. Her catchphrase is "No need to worry!", but she usually says this when there actually is a need to worry. Although she originally planned to participate in the Kanto contests, she decides to remain in Sinnoh when her Buneary is offered to model for a Pokémon magazine. Dawn is very saddened to leave Ash and Brock, but she and Piplup cheer up and wave goodbye as they return to Kanto. She later decides to travel to Hoenn to take part in the contests there in the undubbed Diamond and Pearl post epilogue episode.

She first meets Ash when he mistakes her for a Pokémon. She tends to call Ash a kid, usually when Ash makes a mistake or acts particularly naïve. She has the Dragon-type Pokémon Axew as her companion. She reappeared in the 65th episode of Pokemon Journeys: The Series, but in the same outfit as she appears in Pokémon Black 2 and White 2 (she initially appeared in the outfit she wore back when Ash travelled with her, when Goh mistook her for a Pokemon). In her reappearance, it is revealed that her Axew evolved all the way into a Haxorus, has been training and battling Dragon-type trainers such as Clair (the Blackthorn City Gym Leader) before returning home. She reunites with Ash while battling him in the Opelucid Gym. This episode was to serve as an apology to fans for not letting Ash do the Opelucid Gym in the Black and White series and for failing to evolve Axew within his debut series. She is also revealed to be the new Unova League Champion (like in Pokemon Black 2 and White 2), confirming that Alder no longer holds the title (having defeated him off-screen). While she does put up a good fight, she loses to Ash, causing her rank in the World Coronation series to drop.

After experiencing numerous events like the Sycamore summer camp, she learns about Pokémon Showcases from Shauna and decides to become a Pokémon Performer. Following a heartbreaking loss in her debut Showcase, she cuts her hair and begins wearing a new outfit. After obtaining three Princess Keys, she competes in the Gloire City Master Class Showcase, ultimately going one-on-one with Kalos Queen Aria, whom she is unsuccessful in defeating. Once the Kalos league and Team Flare crisis comes to an end, Serena ponders on future plans. After encouragement from Ash, she prepares to compete in the Pokemon contests that occur in Hoenn.

He, along with his sister Bonnie, continue Brock's running gag, only he drags Bonnie off with his Aipom Arm out of embarrassment when she asks some girl to marry him (except Officer Jenny and Nurse Joy), instead of the other way around. In his early life, Clemont attended an academy studying Electric-type Pokemon. While coming up with a project prior to graduation, he befriended a wild Shinx and later created an electric recharge station. Although he graduated, he and Shinx had a fallout due to the mayor taking Clemont to a special banquet. Fortunately, years later, Clemont made up with his Shinx (now as a Luxio). Out of intense admiration for Ash, he travels with him during seasons 17 to 19 to become a better Gym Leader. This culminates when Ash challenges and successfully defeats Clement at the Lumiose Gym, acquiring his fifth badge in Kalos. Before Ash leaves Kalos, he asks for one final battle with Ash, and the result of the battle is left ambiguous to the viewer. He is a bit different from previous male companions, in that Ash is a sort of mentor figure to him, not the other way around, like Brock and Cilan.

- Voiced by (English): Laurie Hymes
Voiced by (Japanese): Kei Shindō
- Lillie is one of the students at the Pokémon School of Melemele Island who befriends Ash in seasons 20 to 22. Hailing from a very rich family, she loves to study and usually helps the other students with their researches, but somehow has an inherent fear of touching any kind of Pokémon (or if the Pokemon come in contact with her by themselves), despite interacting naturally with Pokémon when she was younger. Four years before her appearance in the series, she somehow developed her a fear of touching Pokémon during a travel with her mother Lusamine and brother Gladion, but slowly learns to overcome it in the series, getting used with an Alolan Vulpix nicknamed "Snowy" she raises from egg before becoming her partner Pokémon, along with other Pokémon. However, after seeing one of her brother's Pokémon, Silvally, it triggers a part of her childhood trauma which causes her to not be able to touch Pokémon again. Her fear later ends when she realizes that Silvally was protecting her from an Ultra Beast called Nihilego, rather than attacking her. Later, after helping some wild Alolan Sandshrew deal with a Tyranitar, the leader Sandshrew evolves into a Sandslash and gives her an Icium Z. She keeps an Ice Stone given to her by Chris in the hope that Snowy will use it to evolve one day. Later, Lillie obtained her father's Z-Ring which she is holding onto until he was found. She appeared in a flashback in an episode of Pokémon Journeys, where she was seen writing a letter to her friends while on a train in search of her lost father, Mohn.

Voiced by (Japanese): Kaito Ishikawa
- Among the students at the Pokémon School of Melemele Island who befriends Ash in seasons 20 to 22, Kiawe is the oldest and most experienced, being the only among them to have cleared Akala Island grand trial to be entrusted with a Z-Ring along with Firium Z that once belonged to his grandfather, becoming the first member of the group who can use Z-Moves.

As the most senior in the class, Kiawe is a very serious person. When he is home he tends to be overprotective of his younger sister. He is also serious when it goes to old traditions, especially with the Z-Ring and the Z-Crystals. When he first sees Ash with the Z-Ring, he shows signs of disapproval, since Ash gets it without completing the challenges. When Ash misplaces a Z-Crystal, he becomes enraged and threatens to send his Turtonator at him. It seems that Kiawe doesn't know how to interact with Water-type Pokémon, as he admits that he wasn't sure of how to deal with Popplio at first, instead having his sister play with it instead. In "When Regions Collide!", Kiawe is shown to be very competitive when he challenges Brock into a real Gym battle at the Cerulean City Gym by using his Turtonator against his Steelix.

- Goh (ゴウ, Gō)
- Voiced by (English): Zeno Robinson
- Voiced by (Japanese): Daiki Yamashita; Kei Shindō (age 6; new series, JN001)
- Goh is a stylish city boy and a new Pokémon Trainer who prefers to stay calm and collected, in contrast to the more instinctive and adventurous Ash. His overconfidence has left him mostly isolated and had no interest in making friends, expect Chloe. However, Goh realized how wrong he was in not making other friends that weren't Chloe when he mets and gets to know Ash. He is also highly knowledgeable about Pokémon, being fairly adept at information-gathering and analyzing, both of which were useful in gathering clues. Despite his deep knowledge of Pokémon, Goh is still a rookie Trainer and lacks experience, best evidenced by his tendency to throw Poké Balls at any Pokémon he encounters, rather than weaken them through battle as is the usual practice. This usually backfires on Goh in the long run. His lack of expertise is also evidenced in his battles, where he shows a tactical, by-the-book approach of exploiting type advantages, but is unable to properly respond against more seasoned adversaries, which leads to a crushing defeat. Goh tends to yell "Go!" when sending out his Pokémon or throwing Poké Balls. Over time, however, Goh has grown as a Trainer through his travels and Ash's influences as he considers him a role model. His dream is to catch every Pokemon to work his way up to Mew. Goh's Pokémon partner is Scorbunny but he sees it as his best friend as it evolved into Raboot then into Cinderace. Goh also has a Sobble but has since evolved into Drizzile and Grookey as his other Pokémon partners.
- Chloe Cerise (サクラギ・コハル, Sakuragi Koharu, Koharu Sakuragi)
- Voiced by (English): Cherami Leigh
- Voiced by (Japanese): Kana Hanazawa
- Chloe is a childhood friend of Goh as she is overly cautious and takes a realistic approach to life as she distance herself from making friends, expect Goh and a couple of others, as she did not talk to Ash very much. When she was little, Chloe liked Pokémon but started to dislike them and acted cold around them, except with the family Yamper at times, because she felt jealous as she did not like that they stole her attention from everyone around her. However, after realizing her behavior, Chloe not only overcame her jealously with Pokémon but also became closer with the family Yamper. Also, Chloe became more open about making friends as she has come to see Ash in that term and has grown to care about Pokémon again. After catching her first Pokémon, Chloe officially became Pokémon Trainer and joins her friends on their research adventures. Chloe's Pokémon partner is a special female Eevee that is incapable of evolving as she is also her best friend.

At the end of season 2 (Orange Islands), Ash and Gary have their first Pokémon battle in which Gary's Eevee beats Ash's Pikachu. When the battle is over, Gary starts on a new journey to Johto and this subsequently influences Ash to follow him there. After losing to Ash in the Johto League, Gary decides to pursue a career in Pokémon research, impeding his rivalry with Ash.

After Ash defeats the Battle Frontier and comes back to Pallet Town, Gary and Ash have a battle between Gary's Sinnoh Pokémon, Electivire, and Ash's Pikachu. Electivire easily beats Pikachu, which inspires Ash to travel to Sinnoh. While in Sinnoh, Gary becomes a Pokémon researcher working with Professor Rowan. By this time, Ash and Gary have become more of friends than rivals and they even team up to protect Pokémon from Pokémon Hunter J. After working together to protect a group of Shieldon from Pokémon Hunter J, they both agree to remain "friends until the end."

She travels in Johto and in "Staging a Heroes' Welcome!" and "Strategy with a Smile!", she makes a cameo appearance along with Harley and Drew, watching May perform live on TV at the Wallace Cup.
- Paul (シンジ, Shinji)
- Voiced by: Kiyotaka Furushima
- Paul is a roaming Pokémon trainer from Veilstone City in Sinnoh. As a Pokémon trainer, Paul is experienced and has traveled across the regional areas of Kanto, Johto, Hoenn and Sinnoh, much like Ash. During Pokémon: Diamond and Pearl, he begins to travel through Sinnoh, where he meets and develops a rivalry with Ash Ketchum. Unlike Ash's previous rivals, Paul is a grumpy and serious trainer whose only concern towards Pokémon is their ability to act in battle and who believes that forming bonds with Pokémon dilutes their potential, and is thereby seen by many characters for being the complete opposite of Ash. His harsh training style, competitive behavior, and desire to be strong derives from his resentment toward his older brother, Reggie, who had been an accomplished trainer until he lost to Pyramid King Brandon, causing him to quit Pokémon training to become a breeder. Paul is determined to make sure he doesn't meet that same fate, so he plans to surpass not just any trainer, but his own brother as well, although he is clearly unlikable to many (e.g., Maylene, Zoey, Roark and especially Ash). In Japan, he is named after Shinji Mikami, the creator of the Resident Evil series. He ultimately loses his battle against Ash in the Sinnoh League. Afterwards, he finds a bit of respect for Ash, and heads out to battle with Brandon. Ash and Paul depart on a good note. Ash wishes him luck, which Paul returns. Just as Paul is about to leave Ash calls out that they should battle again, real soon. Then he smiles, finally accepting him. As he waves good-bye, he walks away, into the sunset. Cynthia states that she would like to see the day Paul and Ash compete in the Champion League. Paul is also seen again in the next episode, watching Ash's battle with Tobias on television. When Ash is defeated, Paul looks disappointed and walks away. He appears in Journeys in a flashback when Gary mentions Ash's Infernape. Paul is designed to be Silver of Pokémon Gold and Silver and Pokémon Crystal because Paul trained his Pokémon through harsh training opposed to forming a trusting relationship with his Pokémon.
- Barry (ジュン, Jun)
- Voiced by (English): Jamie McGonnigal
Voiced by (Japanese): Tatsuhisa Suzuki
- Barry is Ash's rival in Sinnoh. He is an impatient and overconfident boy who, while competent and skilled, tends to lose most of his battles against Ash. He is an admirer of Paul and uses the same technique though he cares for his Pokémon. He dreams of being the strongest Pokémon trainer in the world. Barry is best friends with Kenny and the son of Palmer, the Tower Tycoon of Sinnoh's Frontier Brains. He is based on the rival in Pokémon Diamond and Pearl.
- Nando (ナオシ, Naoshi)
- Voiced by: Kazuya Nakai
- A talented Pokémon trainer and wandering minstrel, Nando is a calm young man deeply conflicted as to whether he should challenge gyms or become a Pokémon Coordinator. After battling both Ash and Dawn, he chooses to pursue both paths, regardless of the difficulty. By the time of the Sinnoh Grand Festival, he has acquired seven Gym Badges and five Contest Ribbons. In the Grand Festival, he is able to reach the Top 4, losing to Zoey. After the Grand Festival, he obtains the necessary badges to compete in the Sinnoh League; he is Ash's first opponent but is eliminated after putting up a good battle. Nando makes his debut appearance in "Dawn of a New Era!". He is usually seen playing his golden Mew harp. The harp has often been shown to attract large groups of wild Pokémon.
- Conway (コウヘイ, Kōhei)
- Voiced by: Kōzō Mito
- Conway is a particularly smart and cunning trainer, who carefully studies and analyzes trainers to create a strategy. He first encounters Ash and the gang during the Hearthome City Tag Battle Tournament, where he battles alongside Dawn and makes their way to the finals, only to be defeated by Ash and Paul. He later meets the gang again at the Pokémon Summer Academy where he is the leader of the Green Team. He later battles Ash in the third round of the Sinnoh League where he loses. A common gag of Conway is that he appears out of nowhere in a creepy manner, of which Dawn is usually the victim.
- Zoey (ノゾミ, Nozomi)
- Voiced by (English): Emlyn Morinelli McFarland
Voiced by (Japanese): Risa Hayamizu
- Zoey is an experienced Pokémon coordinator from Snowpoint City and Dawn's main rival. Unlike most rivals, she often gives out helpful advice and helps out in certain situations instead of fighting and taunting Dawn all the time. Zoey is initially disdainful of those who participate in both Gym battles and contests because she believes that trainers who divide their efforts do not full-heartedly compete in both disciplines. However, she changes her outlook as she meets trainers who are able to successfully manage both while respecting the hard work required. Zoey first appears in the episode of "Mounting a Coordinator Assault". In "A Grand Fight for Winning", she defeats Dawn in the final stage of the Grand Festival and wins the Ribbon Cup.
- Kenny (ケンゴ, Kengo)
- Voiced by: Yūko Mita
- Kenny is one of Dawn's childhood friends and a rival coordinator. He frequently calls her by her nickname, "Dee Dee" and is best friends with Barry. Kenny makes his debut in "Getting the Pre-Contest Titters" and "Settling a Not-So-Old Score", where he and Dawn enter the Floaroma Pokémon Contest. Eventually, he is able to qualify for the Sinnoh Grand Festival, but misses the cut of 32 in the Grand Festival, causing him to leave Lake Valor to improve his training. Kenny is revealed to have romantic feelings towards Dawn and eventually challenges Ash to a battle with the outcome determining who Dawn would travel with. Though he wins the battle, Dawn leaves him a note stating that she wishes to remain with Ash.
- Ursula (ウララ, Urara)
- Voiced by (English): Melissa Schoenberg
Voiced by (Japanese): Ayako Kawasumi
- One of Dawn's rivals, Ursula is a Coordinator from the Sinnoh region who enters the Chocovine Contest at the same time as Dawn. They meet just outside the Contest Hall when her Gabite gets into a confrontation with Dawn's Pachirisu. Her attitude toward Dawn is similar to Harley's attitude toward May. During the Sinnoh Grand Festival, she loses to Dawn and is eliminated from the contest, unable to make it into the Top 16.
- Tobias (タクト, Takuto)
- Voiced by (English): J. Michael Tatum
Voiced by (Japanese): Hiroki Takahashi
- An incredibly powerful trainer, Tobias is mysterious, silent and unbelievably skilled, who apparently earns all eight of his gym badges only using his Darkrai. He competes in the Sinnoh League where, up until his battle with Ash, he manages to single-handedly defeat all of his opponents with just Darkrai. Ash battles him in the semi-finals, during which Darkrai ends up losing to Sceptile. Tobias still earns the victory losing only two Pokémon (Darkrai and Latios). He later wins the Sinnoh League with, once again, just his Darkrai. However, as Cynthia is still Champion in the Black and White series, it is unknown if he actually lost to her or the Sinnoh Elite Four or he chose not to battle them at all. Tobias is universally despised by fans for first appearing in the middle of the League arc with little build-up and using a team of Mythicals and Legendaries in the League, without explanation as to how he acquired them.
- Trip (シューティー, Shūtī, Shooty)
- Voiced by (English): Jamie McGonnigal
Voiced by (Japanese): Akeno Watanabe
- Trip is a male trainer taking the Unova League challenge who appears in the Black and White series and whose ultimate ambition is to compete in the Champion League and defeat Alder, the Unova champion. In addition to being a Pokémon Trainer, he is also an amateur Pokémon photographer. Upon his first meeting and battle with Ash, he tends to somewhat display a discriminatory attitude toward him as being part of the "boonies" because Ash is from the Kanto region, along with his Pikachu, which happens to be extremely rare in the Unova region. Trip participates in the Club Battle, Clubsplosion, Junior Cup, and Unova League tournaments. With the exception of the Junior Cup, which he wins, he loses in the first round of each competition. After his battle with Ash in the Unova League, Trip appears to have ended his rivalry with Ash, and shows an apparent degree of respect towards him. Trip's loss against Alder, the Unova Champion, was to serve as a reminder to fans that a competent but inexperienced trainer cannot easily win against a Champion like in the games. He represents a trainer taking the same journey in real life, just like in the games, but not fully aware of the difference between the game and reality. Trip is also universally hated by fans for being a bland knockoff of Paul and Gary, as well as the fact that his inexperienced Snivy defeated Ash's Pikachu (even though Zekrom disabled Pikachu's Electric attacks). Due to Iris being the Unova Champion in Journeys, it is implied that Trip failed on accomplishing his goal of defeating Alder.
- Bianca (ベル, Beru, Bel)
- Voiced by: Shizuka Itō
- Bianca is a female trainer who appears in the Black and White series. She encounters Ash and his companions several times throughout the series which usually ends with a battle between herself and Ash. She is also shown to be very excitable and clumsy. Bianca joins Ash, Iris and Cilan to participate in the Club Battle, Clubsplosion and Unova League tournaments. A running gag in the anime shows that when she encounters the group, she ends up pushing Ash into a nearby body of water, like a fountain or a river, much to Ash's dismay.
- Burgundy (カベルネ, Kaberune, Cabernet)
- Voiced by: Ikumi Hayama
- Burgundy is a female Pokémon Connoisseur who at one point challenged Cilan and lost and Cilan said that her Oshawott was not compatible with her (Cilan however, doesn't remember this, but he does remember their gym battle). When Ash, Iris and Cilan meet up with her once more, after she says that none of Ash's Pokémon are good for him, she reveals she challenged the Striaton Gym and got the Trio Badge, but still feels she needs to fight Cilan. Cilan defeats her again, but she exclaims she will fight him again someday and win. She later participates in the Club Battle, Clubsplosion, and Junior Cup tournaments with the group, held in Nimbasa Town, Ambiga Town and Lacunosa Town respectively, but loses in round one in all of them. She also tried to help a millionaire's daughter find a perfect Pokémon partner, but due to being a C-Class Connoisseuse (an inexperienced and first level of Connoisseur rank) and the fact she tried to find the partner while in disguise, she ends up being rejected.
- Georgia (ラングレー, Rangurē, Langley)
- Voiced by: Misato Fukuen
- Georgia is a female trainer who calls herself a Dragon Buster, someone who specializes in defeating Dragon-type Pokémon. Incensed, Iris challenges her and the fight between Georgia's Beartic and Iris's Excadrill where Excadrill loses allows Iris to make Excadrill feel better about their loss to Drayden several years earlier. Georgia ties with Iris in a second battle, as Excadrill learned Focus Blast and gained trust in Iris. Georgia participates in the Club Battle, Clubsplosion, and Junior Cup tournaments with Ash, Iris and Cilan. She does become a bit nicer to Iris during the Ferroseed Research Center crisis.
- Stephan (ケニヤン, Keniyan, Kenyan)
- Voiced by: Tomohiro Waki
- Stephan is a male trainer whom Ash meets on the way to Nimbasa City. He and Ash have a battle, which Ash wins. Stephan participates in the Club Battle and Clubsplosion tournaments with the gang, the latter in which he and his Sawk win. He also participates in the Unova League, where he makes it to the Top 16. Here, he and Ash have an intense three-on-three battle in which Ash defeats him. There is a running gag in the anime that people always mispronounce his name (similar to Butch), but everyone begins pronouncing his name right by the time the Unova League begins.
- Cameron (コテツ, Kotetsu)
- Voiced by: Kōki Uchiyama
- Cameron a rival of Ash's. He debuts after the Junior Cup, as he meant to compete, but did not arrive in time. Cameron temporarily joins the group when he goes to earn his eighth Gym Badge from Marlon in Humilau City, and upon obtaining it, he leaves. Cameron returns to compete in the Unova League tournament alongside Ash, Trip, Stephan, Bianca and Virgil. In the Vertress Conference, he defeats Bianca (leaving her in the Top 64) and during the Top 8 manages to defeat Ash despite being one Pokémon short, but is subsequently defeated by Virgil in the Top 4. He seems to be unorganized as he misinterprets pretty much everything, such as thinking he needed seven gym badges to compete in a Pokémon league instead of eight. The Unova League match where Cameron defeated Ash was seen as a sick joke to many fans, even though there were already additional problems (e.g., most of Ash's Unova members used here (Boldore, Pikachu, Pignite, Oshawott, Snivy, Unfezant) were poorly developed and were not fully evolved at all).
- Virgil (バージル, Bājiru)
- Voiced by: Yūki Kaji

He saves Ash and his group when they fall off a bunch of rocks while trying to climb up to get to Vertress City, where Ash participates in the Vertress Conference.

It was revealed that as a young boy, he once got lost in the forest with his first Eevee, when it suddenly evolved into an Umbreon and was thus able to lead him out. This event made him fascinated with the Eevee species and led to him becoming an Eevee trainer. Virgil is the only one of Ash's rivals with whom he has not battled. Although he won the League, he did not succeeded in becoming the Unova Champion as Iris is the Unova Champion in Journeys.

She and Serena eventually settle their dispute and have a more friendly rivalry. During her time with the group, Miette soon realizes Serena's true feelings for Ash and warns her that if she doesn't confess her feelings, than she will admit her own feelings and take Ash for herself (she also considers Ash as her and Serena's ''other competition'' aside from Pokemon Showcases). Miette soon meets up with Serena and the group again as she had decides to become a Pokémon Performer and is revealed to be entering the same Showcase as Serena. Miette puts on a dazzling performance, but Serena wins and earned her first Princess Key. Miette would later participate in the Master Class Showcase but is defeated by Serena once more.

One day, Gladion found an injured Eevee and brought it to Hobbes. Gladion was very concerned about Eevee, though Hobbes promised it would recover if they took it to the Pokémon Center.

- Hau (ハウ, Hau)
- Voiced by: Jun Fukuyama
- Hau is a cheerful boy, who, unlike other rivals, does not humiliate his opponents. Hau once fought against his grandfather, Hala, but his Dartrix ended up being defeated by his Crabrawler. Hala stated that Hau had to prepare himself the next time they'd face, since Hala would have to use his very best in testing the boy. Hau was gone from Alola for some time, but returned with his father to take on the Island Challenge. Hau was training his Dartrix when the latter bound Ash, Pikachu and Rotom to a tree, thinking of them as its enemies. Soon, Ash and Hau initiated a conversation, where Hau learned that Ash battled his grandfather, Hala, in a Grand Trial. Hau admitted he faced Hala before, but failed; this time, he came back to Alola to complete the Island Challenge. Ash encouraged Hau, and showed Rowlet, who was sleeping. As Dartrix showed some interest, the two guys started a battle, in which Ash attempted to use the Z-Crystal. However, his fingers slipped and Rowlet was defeated. Hau cheered for this fun battle, and decided to take on Ash the next day, since he had things to do with his father. On that day, Ash came with Rowlet late, and apologized, since he was training. This time, Rowlet used Seed Bomb to attack Dartrix, who learned about this strategy and knocked off its Everstone that it launched. However, Ash attempted and succeeded in having Rowlet use Bloom Doom to defeat Dartrix. Hau fell to his knees, but congratulated to Ash for winning the battle. Ash encouraged Hau, who wanted to continue his Island Challenge, and have a Z-Move ready to execute against Ash the next time they'd meet, as the two parted ways. Both Ash and Hau competed against each other in the Alola League, where Ash merged victorious. Afterwards, he watches the rest of the league and help stop the Guzzlord invasion.

- Horacio (ハヤテ, Hayate)
- Voiced by: Nozomu Sasaki
- Horacio was arrogant and condescending, believing that his Charjabug's top-class equipment and Speed-increasing nature would allow him to win the race with ease. He was also a bad sport, mocking Sophocles and the latter's Charjabug. He also disregarded the well-being of his Pokémon, by not allowing his Charjabug to take a break during pit stops, resulting in Charjabug being too exhausted to continue and allowing Sophocles and his own Charjabug to get ahead of them. This was seen again in Evolving Research!, when he arrived at a bridge with the Bug Stone at the other side. He disregarded Sophocles's warning about the bridge being unstable and continued on, resulting in the bridge collapsing, and he had to be saved by Sophocles's Vikavolt. Horacio has mellowed down his arrogance since then and respects Sophocles, which still continues during the Vikavolt race.
Kanto Gym Leaders
All eight Gym Leaders from the Kanto region. During Ash's Indigo League quest, Ash only earned four badges legitimately (Three of them were from Lt. Surge, Koga and Blaine. In the Viridian City Gym, Ash face the Team Rocket trio who were substituting for Giovanni. Because Ash did defeat the Team Rocket Trio in battle, it is a legit win). For more information on Misty and Brock, see the protagonists section. For more information on Giovanni, see the Antagonists section.
- Lt. Surge (マチス, Matis)
- Voiced by: Fumihiko Tachiki
- Lt. Surge is the Electric-type Gym Leader from Vermillion City. Rude, arrogant and loud, he views challengers as "babies" unless they defeat him and prefers to evolve his Pokémon as soon as possible. One of the most dangerous tactics is his reliance on brute strength and has defeated multiple trainers with that tactic. He looks down on anyone with non-fully evolved Pokémon.
- When Ash first fought him, Pikachu was easily overwhelmed in terms of brute strength. Afterwards, while Pikachu was recovering, Nurse Joy gives Ash a Thunder Stone which will allow Pikachu to evolve into Raichu. However, Pikachu refused the Stone, which meant that Ash needs to rely on alternate strategies to win against Raichu.
- When it was time for a rematch, Ash was able to exploit Lt. Surge's Raichu's fatal flaw. Because Lt. Surge evolved his Raichu as soon as it was caught as a Pikachu, it only learned brutal attack strategies and not speed tactics. Ash was able to use Pikachu's tail to ground the electricity and use his speed to knock out Raichu. Afterwards, Lt. Surge stops being rude to Ash and congratulates and respects him on the win.
- He appeared in a flashback in Diamond and Pearl episode. In Journeys, Surge is away from his Gym for training and has one of his assistants, Visquez, to take over the Gym. It is mentioned by Visquez that Lt. Surge's Raichu taught her own Raichu how to battle and Ash's victory in his Gym is widely acknowledged.
- Sabrina (ナツメ, Natsume)
- Voiced by: Kae Araki
- The Psychic-type Gym Leader of Saffron City and one of the two villainous Gym Leaders Ash encountered (the second being Giovanni). It is revealed she came from a family of psychics, and she has psychic powers as well. Unfortunately, she grew way too obsessed with developing them, making her an emotionless Gym Leader while her eerie cheeriness is manifested in a form of a doll, resembling her younger self, creating a split personality. Although she hosts a school to train Psychics, she can also use her powers to turn any defeated challengers (and even her own mother, Misty and Brock!) into dolls for her dollhouse.
- At first glance in her debut series, she appeared as a young girl who helped Ash and co. from Team Rocket. She almost succeeded in turning Ash into one when he forfeits her battle against her Abra/Kadabra but was saved by Sabrina's father.
- Her father told Ash to acquire a Ghost-type Pokémon to counter Psychic-types. After befriending a wild Haunter, he takes it back to the Gym. At first, things were looking bad for Ash as Haunter was nowhere in sight and he had to use Pikachu against Kadabra. Luckily, Haunter appears and starts cheering Sabrina up by making funny faces. Sabrina laughed which caused her and Kadabra to be incapacitated, and both personalities merged together as one, and she loses her match with Ash. While Haunter stayed behind to stabilize Sabrina's mentality, she gives Ash her Gym badge for making her laugh and become friendly again. Sabrina is the fourth Gym Leader Ash faces, instead of the sixth like in the games.
- Erika (エリカ)
- Voiced by: Kyoko Hikami
- The Grass-type Gym Leader of Celadon City, Erika also runs a perfume shop, which contains the essence of her Gloom as her main ingredient. As a child, she had a nasty run in with a wild Grimer. Fortunately, she was saved by a wild Gloom, which drove the Grimer off. Since then, the two became inseparable. In her debut, while everyone enjoyed the perfume scent, Ash insulted the perfume. A furious Erika and her employees kicked him out and banned him from the store. Ash tried to enter her gym, which is also a greenhouse, next, but her employees threw him out as well as they heard about him insulting the perfume.
- With no options left, Ash sought help from Team Rocket after they were caught and thrown out for attempting to steal the perfume. Posing as a girl named 'Ashley', he was able to gain access and become a student and learned more about Erika's background. Unfortunately, his disguise was unveiled and he challenges her to a Gym Battle. However, during the match, the Gym gets sent on fire thanks to Team Rocket starting a fire in the Gym. Everyone had to evacuate and put out the fire. Although Ash felt guilty of being part of this retaliation, he immediately goes in and rescue Erika's Gloom who was trapped inside the burning building. Both Erika and Ash made peace with each other and she gave Ash his Rainbow Badge for saving her Pokémon. She is the fifth Gym Leader Ash encountered rather than the fourth like in the games.
- The anime version of Erika has been loathed by Western fans for her being a clueless and irresponsible Gym Leader, such as unintentionally letting her staff banning challengers just because they don't like her perfume.
- She appears in Pokémon the Movie: I Choose You, which is a separate timeline. In the film, Ash does defeat Erika and earn his badge. Erika is much nicer in the film, as it was done to make her close to her game counterpart and serve as an apology to Western fans for making her a complete jerk in the anime.
- Koga (キョウ, Kyo)

Although the battle was interrupted by Team Rocket, Ash and Koga resumed their battle where Ash merged victorious. Koga is the sixth Gym Leader Ash encountered rather than the fifth like in the games.
- He reappeared in a flashback episode in the Black and White anime when Ash was reminiscing his days with his Charizard.
- Blaine (カツラ, Katsura)
- Voiced by: Toshiya Ueda
- Blaine is the Fire-type Gym Leader of Cinnabar Island. He closed down his Gym prior to his debut appearance, as the island became a tourist attraction, due to the hot springs and runs an inn. He challenges people with riddles and tends to make puns even at inappropriate times. By providing riddles to Ash, Misty and Brock, Misty solves each one which led them straight towards to his gym, where Blaine revealed himself. Ash fought him on a three on three battle, but forfeited due to Pikachu almost falling into the lava and Charizard's disobedience. This battle is also infamous for Pikachu using Thunderbolt on Blaine's Rhydon's horn, knocking it out (Rhydon is a Ground and Rock type and is immune to Electric attacks).
- Later, after stopping a volcanic eruption, thanks to Team Rocket's actions, Ash battles him in a rematch and emerges victorious.
Orange Island Gym Leaders
Upon learning about a League there, Ash decided to participate. Unlike in the other regions where there was eight Gym Leaders, Ash faces off against four. None of the Gym Leaders specialize in a certain type, but more on how to do tasks and win challenges to earn a badge, while interacting with their Pokémon. Once the challenger acquires all four Gym Badges, they earn the right to face off against the Supreme Gym Leader. Should the challenger succeeds, then they got into the Hall of Fame and are Champions (but not official region Champions). The format is similar to the player facing the Elite Four and the Champions just like in the games.
- Cissy (アツミ, Atsumi)
- Voiced by: Miki Nagasawa
- Cissy is the Gym Leader from the Mikan Island Gym of the Orange Islands and Senta's older sister. In order to obtain the Coral-Eye Badge, trainers must win in an accuracy test and a race against her by using Water type Pokémon. When facing Cissy as his first Orange League Gym Challenge, Ash had to participate in two contests against her. Using her Seadra against Ash's Squirtle in an accuracy test, both sides had an equal precision for hitting the cans and the result was a tie. Before the race, Team Rocket stole Cissy's Blastoise, but were blasted off. In the aquatic race, Ash was losing (as Blastoise pushed Lapras), but Ash's Lapras froze the water so that it could slide on it, making Ash win the race and the badge.
- Danny (ダン, Dan)
- Voiced by: Yasunori Matsumoto
- Danny is the Gym Leader of the Navel Island Gym from the Orange Islands. Danny approached Ash, Misty and Tracey and complimented Misty, causing her to be flattered.

After this revelation, Ash and Danny had three challenges. He used Nidoqueen against Ash's Lapras to freeze the geyser and won. The next challenge was to shape the ice like a sledge, which Ash won as his Charizard burned him, melting the parts of the ice. The last challenge was a race, but it was temporarily stopped due to Team Rocket's attempt. Ash and Danny continued the race and while the odds were in Danny's favor, Ash's slide spun around and he landed in the sea. But luckily, Ash managed to win the race and the badge.

While the gang was on the way to the island they spotted a little girl, who happens to be Rudy's little sister. Misty saved the little girl and Rudy falls instantly in love with Misty. Ash and Tracey were confused about this but Misty was excited about it. Eventually, Rudy wanted Misty to stay with him for good. He had a battle with Ash, using the Pokémon's dancing moves to evade the attacks and counter them. He saw that Misty actually cared for Ash more than him. Knowing it was the right thing to do, he let her go and continue her journey.

- Drake (ユウジ, Yūji)
- Voiced by: Kōji Yusa
- Drake is the strongest trainer of the Orange Islands and Champion (Supreme Gym Leader) who resides on Pummelo Island. Despite his skills as a trainer, he grew bored with being unbeatable and wondered if there was going to be a challenger to defeat him. Many trainers who challenged him lost either early in the game or when he uses his ace Pokémon, Dragonite.
- Eventually, Ash arrived with his four Orange Island badges which earned him the right to face Drake. This is the first time in the series where we get to see a full 6 on 6 battle. At first, Ash was able to consecutively defeat four of Drake's Pokémon (one of the battles ended in a tie). Things took a turn for the worse, when Drake uses his Electabuzz and his Dragonite to wear down four of Ash's remaining Pokémon. Eventally, Ash was able to use Pikachu to defeat Dragonite. Ash was made Orange Island Champion as a result. The Orange Islands achievement gets referenced a couple times in the series and Ash's Orange Island trophy makes a cameo in the second episode of Journeys.
- Ditto is the first Pokémon Drake uses and many trainers failed to defeat Ditto, which can mimic their Pokémon's moves. Drake always uses his Dragonite last in battles.

The eight Gym Leaders from Johto and members of the Johto League.
- Falkner (ハヤト, Hayato)
- Voiced by: Akira Ishida

- Bugsy (ツクシ, Tsukushi)
- Voiced by: Hiromi Ishikawa
- Bugsy is the Bug-type Gym Leader from Azalea Town. When Ash and co. first arrived in the Gym, he was nowhere to be found. However, after Misty gets startled by the Bug-types in the Gym, she unintentionally knocked down a ladder as Bugsy was viewing them from a tree. Bugsy criticized Misty for her ignorance towards them. Afterwards, Ash challenges Bugsy to a Gym battle which he accepts and had to help down from the tree.
- Bugsy used a variety of defense tactics against Ash's Pokémon to cover up type disadvantages. However, as he failed to cover all the weak spots, Ash found an opening and defeated all of Bugsy's Pokémon easily.
- Whitney (アカネ, Akane)
- Whitney is the Normal-type Gym Leader from Goldenrod City. Her uncle, Milton, owns a Miltank dairy farm which produced delicious Moomoo milk. This is where Whitney was able to obtain her Miltank.
- In her debut appearance, she and her Clefairy bumped into Ash and Pikachu. She kisses Pikachu's bruised forehead, much to his amusement. She took Ash and co. all around the city, where they ended up taking wrong routes. Team Rocket attempted to steal her Clefairy, but they sent Team Rocket blasting down the unfinished magnet train rail, which would not be completed for a year (In Black and White, the magnet train rail was completed, implying a year has passed since Ash's Johto Journeys). When it was time for the Gym battle, Ash was able to defeat Whitney's female Nidorina easily and her Clefairy forfeited due to using Splash (via Metronome). Unforunately, Whitney turns the tables and flattens his Pikachu, Cyndaquil and Totodile using Miltank's Rollout.
- The next day, Whitney invited Ash and co. to her uncle's dairy farm where they enjoyed the milk and learn how to handle a Miltank. When Team Rocket used a Barrel-shaped mech to attack the farm, Ash came up with a strategy counter the Rollout tactic. Using it, he was able to defeat Whitney. Although the rematch took place outside her Gym, Whitney counted it as an official win and gives Ash his Gym badge. Unlike in the games, Whitney does not cry and throw a tantrum when she does lose. It is also revealed in the next episode that whenever someone merges victorious against Whitney, they get interviewed on DJ Mary's radio station. She later appears in a few flashbacks.

Afterwards, he and Ash had a Gym battle where Ash merged victorious. It is interesting to note that Morty uses all three members of the Gengar line (Gastly, Haunter and Gengar), despite the introduction of Misdreavus in the Generation II games. His tactics were primarily on scaring and confusing his opponents disabling their concentration, invisibility and relying on Normal-type immunity.
- While heading to Mahogany Town, Ash and friends arrived in Ectruteak City again and run into Morty and his friend, Eusine.

Jasmine called off the battle and berated her apprentice for her antics. Jasmine could not battle Ash at the moment as her Ampharos, she kept at the lighthouse, was sick. She had to send Janina on an errand to fetch the medicine from Cianwood City and informs Ash that there is a Gym there he should try out while waiting. Unfortunately, even though Ash won his gym battle there, Ampharos was still recovering so Ash and co. decided to visit the Whirl Islands instead. Afterwards, the heroes returned to Olivine City as Ampharos was fully recovered and now Jasmine was ready for battle. Despite putting up a good fight, Jasmine loses to Ash.
- Sometime later, Jasmine went to visit Sunyshore City in Sinnoh. Ash and co. met her shortly after his victory against Volkner. Here, she was watching Kenny do a series of contest combinations.

- Pryce (ヤナギ, Yanagi)
- Pryce is the Ice-type Gym Leader from Mahogany Town. Pryce and his Piloswine were best friends in their early days as a Trainer and spent battling many other trainers. After losing to a Magmar, both Pryce and Piloswine suffered severe burns. While recovering, Piloswine left one night with no explanation and disappeared. Since then, Pryce grew bitter towards challengers and their Pokémon.
- He refused to battle Ash due to the belief that Pokémon can't be friends and he viewed Ash's strategies as weak. However, while battling Team Rocket, both Ash and Pryce came across a cave where his Piloswine was found frozen. It turns out that Piloswine tried to find herbs and berries to cure their burns but ended up frozen in the process. Pryce stopped being rude and helped Ash and co. defeat Team Rocket. Afterwards, Pryce accepts Ash's Gym Challenge. Although Ash and Pryce both put up a good fight, Pryce forfeited his match as his Piloswine was too exhausted and Ash knocked it down three times, which ruled as a T.K.O. This is the only time where Ash won his Gym Badge with the Gym Leader forfeiting the battle.
- Clair (イブキ, Ibuki)
- Voiced by: Yuko Mita
- Clair is the Dragon-type Gym Leader from Blackthorn City. She was revealed to have mentored Lance of the Kanto Elite Four. Ash, Misty and Brock first encountered Clair when her Dratini had to shed its skin. While Team Rocket attempted to steal Dratini, Clair and Ash had to help protect it which caused Dratini to evolve into a Dragonair. Shortly after, she had to perform a ritual to purify a Dragon Fang at Riverhead Falls, before accepting Ash's challenge.
- When Ash and Clair were battling, Team Rocket stole the Dragon Fang, causing the battle to called off. Ash and co. chased after them and prevented a Dragonite from going on a rampage and put out the fire that was threatening the Dragon Holy Land. Once everything was cleared up, Ash and Clair resumed their Gym Battle where Ash merged victorious and earned his final badge. Unlike in the games, Ash did not have to do a cave trial to earn the badge and Clair is not a sore loser.
- She appeared in a flashback in a Diamond and Pearl episode. She officially reappears in the Decolore Islands arc, where she was searching for a Shiny Druddigon that lived in Cave Island. During this quest, she reunites with Ash and met his Unova companions, Iris and Cilan. After calming down the Druddigon, Clair catches it and heads back home to Blackthorn City, but not before agreeing with Iris for a battle. In the undubbed post-Black and White series episodes, Iris went with Clair to the Dragon Holy Land where they encountered and calmed a wild Gible. Iris later battled Clair and lost.
Hoenn Gym Leaders
The eight Gym Leaders for the Hoenn League. During Ash's Hoenn League quest and Sinnoh League quest, Wallace was Hoenn champion at the time, hence why Ash never fought him and he is not listed here.

- Roxanne (ツツジ, Tsutsuji)
- Voiced by: Yuri Shiratori

- Brawly (トウキ, Tōki)
- Voiced by: Kōhei Kiyasu
- The Fighting-type Gym Leader from Dewford Town, Brawly is a professional surfer and owns a private island where he teaches people how to surf. It is revealed that he once trained under Chuck. Ash wanted to battle Brawly, but he spends most of the time surfing. Unbeknownst to Ash, the surfing tactic was Brawly's way of how to dodge attacks, while maintaining balance and focus. When Brawly battles Ash, he beats Ash and his Treecko easily with his newly evolved Hariyama. Ash was harshly berated by his friends for making his Treecko continuing to battle despite gaining numerous injuries against Hariyama as well as his arrogance. After learning his lesson, Ash learned how Brawly was able to use surfing as a strategy and taught his Pokémon that tactic. Ash decided to stay on Dewford Island for a while to train for his rematch.
- When a storm arrived, he interrupted Ash's battle with one of his students, Shauna, forcing everyone to seek shelter in a cave. He refereed Ash's match with Shauna with Ash merging victorious. Shortly after, Ash was able to defeat Brawly in a rematch, while using the geysers to his advantage.
- Wattson (テッセン, Tessen)
- Voiced by: Ken'ichi Ogata
- Wattson is the Electric-type Gym Leader from Mauville City. He is usually portrayed as a jolly old man. In his debut appearance, Ash and pals entered his Gym through a roller coaster ride. Along the way, they came across a mechanical Raikou which attacked the heroes. Thinking it was the real Raikou, Ash ordered Pikachu to attack it which not only damages the robot, but also supercharges Pikachu's electric attacks. When it was time for the battle, Ash earned his victory (albeit lopsided) by having Pikachu one-hit knock out all three of Wattson's Pokémon. Although it was a legit win and Ash earned the badge, Wattson started to get upset and sat near the Mauville plant to think about what happened. Fortunately, a wild Electrike greeted him and cheered up Wattson. After Ash explained what had happened in the battle, Wattson allowed Ash to keep his badge.
- Later as Ash and friends were heading back to Petalburg City for Ash's Gym battle against Norman, they ran into Wattson again. Ash and Wattson had a friendly battle with Wattson's Manectric defeating Ash's Torkoal.
- Flannery (アスナ, Asuna)
- Voiced by: Rio Natsuki
- Flannery is the new Fire-type Gym Leader of Lavaridge Town. She inherited the gym from her grandfather, after he retired and became a poet. As a new Gym Leader, Flannery tends to make a lot of errors in her duties such as forgetting to hire a referee (luckily, her grandfather decided to be the referee) and she sought Ash and his friend's help to clean up the battlefield for Ash's Gym Battle.
- While battling Ash, she does have surprisingly good tactics such as using Smog and Sandstorm attacks to provide ambush tactics. However, due to her overusing Overheat (power level decreases after every use) and her stress temperament, Flannery ended up costing her Gym battle victory. However, her grandfather commended her for putting up a good battle.
- Winona (ナギ, Nagi)
- Winona is the Flying-type Gym Leader from Fortree City. She has a habit of praying to the sky to grant her good luck before a battle starts. She first appears in the show giving children a ride on her large Skarmory at the Fortree City Feather Carnival. Before her battle with Ash could take place, she and the heroes had to stop Team Rocket from stealing the various Pokémon at the Carnival. Afterwards, she has her official Gym battle with Ash, where she loses.
- In her battle, she uses flight paths and angles for accurate attacks with her Pokémon. She learns how to adapt to various weather conditions (e.g., windy days). The Fortree Gym battlefield is out in the open, allowing her and her opponents Pokémon to fly and fight. Her Swellow in the anime is a shiny to differentiate hers and Ash's Swellow during the final battle.
- Tate and Liza (フウとラン, Fū & Lan)
- Tate and Liza are fraternal twins of the Psychic-type Gym in Mossdeep City. Their father, Jin, works as an astronaut and director of the Mossdeep Space Center, alongside their mother, Rachel, the mission control operator. Although twins, Liza is slightly older by a few minutes, and constantly teases Tate about it. Sometimes the twins tend to bicker too much, which causes them to lose focus in battles, allowing their opponents take a free hit. Despite this, the twins care for each other deep down.
- In their first appearance, the twins give Ash and friends a tour of the Space Center, and let them experience a zero-gravity room using only their Baltoy. They later help Ash and co. stop Team Rocket from stealing a space shuttle that was intended to be used for Jin's space exploration.
- Following the space shuttle launch, Tate and Liza challenge Ash into a Double Battle, with Rachel refereeing the match. However, while trying to attack Ash's Pikachu and Swellow, both their Solrock and Lunatone's attacks keep cancelling each other out. As a result, the twins kept bickering more allowing Ash to score free hits. Eventually, they were able to patch up the mess, after stopping Team Rocket from stealing Solrock and Lunatone. As the battle resumes, both Tate and Liza countered all of Ash's tactics while in sync, but lose due to Pikachu and Swellow's "Thunder Armor" tactic. Both of them realized that they still need to improve their attack combinations and remain in sync with each other.
- Juan (アダン, Adan)
- Voiced by: Shō Hayami
- Since Wallace was Hoenn Champion at the time, his mentor, Juan, served as the Water-type Gym Leader of Sootopolis City. Juan was a Top Coordinator in his early life and loves Water-type Pokémon due to their streamlined characteristics and weakness to Electric Types. He is widely popular amongst women and puts on spectacular water shows.
- During his battle with Ash, the Gym battle was broken into two parts. The first part was a double battle. If the challenger defeats the two Gym Leaders' Pokémon, then they move on to the second part, which is a three on three battle.
- His battle tactic is using rapid attacks making the opponent having trouble hitting the targets. Despite this, Juan loses to Ash and congratulates him on earning his eighth and final badge for the Hoenn League. He appears in a flashback in a Diamond and Pearl episode.
Sinnoh Gym Leaders
The eight Sinnoh Gym Leaders and members of the Sinnoh League.
- Roark (ヒョウタ, Hyōta)
- Roark is the Rock-type Gym Leader from Oreburgh City, foreman of the Oreburgh Mine and leader of the Ancient Pokemon Expedition Orienations. He inherited the Gym from his father, Byron, when Byron moved to Canaclave City, which would allowed Roark to further his own career. He first appeared in the show, where Paul was able to battle and defeat Roark easily, despite two of Paul's Pokemon were at a disadvantage. Ash later challenged Roark to a Gym battle, while Paul watched, but loses due to focusing too much on pleasing his rival and the fact that Roark's Cranidos wore out his team fast. Afterwards, Paul leaves disgusted with Ash's performance.
- While training for a rematch, Roark provides Ash advice on using a strategy that Ash is familiar with, while reminding Ash that to win battles, concentrate on the current opponent and not the potential opponent. It is implied that Roark does not like Paul, as when Ash mentions about Paul's win, Roark felt uncomfortable stating that it "has been eating [him]". He helped Ash and his friends stop a rampagaing Aerodactyl and sent Team Rocket blasting off with his newly evolved Rampardos. The next day, Ash goes in for a rematch and violently defeats all of Roark's Pokémon, due to Roark being too slow in adapting to Ash's new tactics which included the improvised Spin Dodge and defense strategies.
- Roark later appears during Ash's visit at Canaclave City where Ash learns that Byron, the Canaclave Gym Leader, was in fact, Roark's father. Both father and son defeated and stopped Team Rocket from stealing the fossils. Roark later refereed Ash's Gym Battle against Byron.
- Roark's tactics are all about using fast and offense attacks. His signature Pokémon, Cranidos/ Rampardos, is capable of utilizing these tactics. However, he has very poor defense tactics, which Byron always reminded Roark to use as well.
- Gardenia (ナタネ, Natan)
- Voiced by: Chieko Honda
- The Eterna City Gym Leader and a Grass-type Specialist, Gardenia always gets overenthusiastic when coming across a Grass-type Pokemon, such as James' Cacnea and Carnivine and Ash's Turtwig, causing her to cuddle them a lot much to the Pokémon's displeasure. She first appeared in Eterna Forest arc, when Ash and friends help Cheryl reach the Combee hive. Ash had a practice battle with Gardenia, but forfeited as her skills were too overwhelming. She later appeared to help stop Team Rocket from stealing the Adamant Orb, while clearing Nando, who was framed for the crime. This is where Gardenia reveals herself as Gym Leader. Shortly after, Gardenia then got to battle Ash in an official Gym battle, where he merged victorious.
- Gardenia appeared one last time where she and James engaged in a Tag Battle against Ash and Dawn, but lost. During the battle, Gardenia reveals that Cacnea can learn Drain Punch and offers to train Cacnea to make it stronger, to which James refused. However, because James did not properly train Cacnea and felt insecure, it could not execute Drain Punch properly. After consideration, he tearfully gave away his Cacnea to Gardenia to master the Drain Punch move. It is later revealed by Barry that she was successful, much to James' joy.
- Gardenia's tactics is to rely on sunlight to make her Pokemon's moves powerful. However, due to over relying on the sunlight, she ended up costing her Gym Battle victory to Ash.
- Maylene (スモモ, Sumomo)
- Voiced by: Aya Endō
- Maylene is the Fighting Gym Leader from Veilstone City (the same city where Paul, Ash's Sinnoh rival, and his older brother, Reggie, hail from). Six months prior to her debut appearance, Maylene became a Gym Leader, due to being a formidable opponent alongside her Lucario. However, due to the stress and new responsibilities and duties she had to carry out, she ended up losing focus too often. When Paul defeated Maylene easily due to both type-advantage and her lack of concentration, Paul called her "the weakest Gym leader [he's] ever fought."
- Maylene bonded with Dawn as the two were struggling throughout their careers but they decided to battle to give each other confidence, while Ash went to train with Paul's older brother, Reggie. After Dawn loses to Maylene, Maylene battled Ash next. Although the battle ended in a draw, she gave Ash the win. This is the only time where Ash's Sinnoh Gym battle ended in a tie. She returns one last time to help Ash and the gang stop Team Galactic from stealing the Veilstone City Meteorites. It appears that she might have feelings for Reggie as he is nice to Maylene, unlike Paul.
- Crasher Wake (マキシマム仮面, Makishimamu Kamen, Maximum Mask)
- Voiced by: Tetsu Inada
- The Water-type Gym Leader from Pastoria City, Crasher Wake is also a professional wrestler. He first appeared in the anime where he brings Ash, Dawn and Brock to the Pastoria Crogaunk Festival, as he is serving as one of the judges there. Fortunately, he accepted Ash's challenge for the following day. When it was time for the Gym battle, Ash was able to use Pikachu and Buizel to take out all three of Crasher Wake's Pokemon easily.
- Crasher Wake is the only Sinnoh Gym Leader Ash was able to defeat without losing his own Pokemon in battle. Crasher Wake's Pokémon have a large amount of stamina, such as his Floatzel being able to use his floatation sac to stop various oncoming moves including Giga Impact. Crasher Wake also uses the underwater portion of the battlefield for ambush tactics and sensing opponents above water.
- Fantina (メリッサ, Melissa)
- Voiced by: Kikuko Inoue
- Fantina is the Ghost-type Gym Leader of Hearthrome City and a former Top Coordinator. Much like in the games, although Ash and his friends visit Heathrome City early on in the series, Fantina was not available to battle and was often away training. Ash does not properly meet Fantina until he sees her training with Zoey for an upcoming contest. When Ash had a practice battle with Fantina, he was easily overwhelmed by her reliance on her favorite move, Hypnosis, which her Pokémon Gengar and Drifblim can use (Mismagius cannot learn Hypnosis).
- Sometime later, Fantina returned to her Gym to make up for not doing Gym battles, as Paul revealed to have won his badge from her. She also battled Barry, who forfeited his match as he failed to knock out one of her Pokémon. When it was time for her showdown with Ash, it is revealed that Ash developed a "Counter Shield" tactic which was capable of both blocking and injuring opponents. He wipes the smirk off Fantina's face and defeats her by using "Counter Shield" along with close range attacks, much to Barry's amazement while watching the battle. Fantina later appears as a judge for the Sinnoh Grand Festival.
- Her battle style is all about relying on moves that cause status conditions such as Hypnosis. However, because of her over reliance on her signature move, Hypnosis, as well as her poorly developed "Counter-Counter Shield", she loses to Ash.
- Byron (トウガン, Tōgan)
- Voiced by: Kazuki Yao
- Byron is the Canaclave Gym Leader, Steel-type specialist and father of Roark. Originally, Byron used to run the Oreburgh Gym, but moved to Canaclave City, as there were more fossils located there and a vacant spot in the Gym opened up. His reason for letting Roark inheriting the Oreburgh Gym was for Roark to develop his own career. Despite his tough demeanour, Byron does love his son and his unseen wife and even kept the Sunkern Fossil, which Roark discovered as a child.
- In his debut, he was in the middle of a family feud with Roark, while Ash arrives in the Gym. Roark calls out his father on his absence, which resulted in a feud becoming an intense showdown (Roark's Rampardos vs Byron's Bastiodon) of which Fossil Pokémon is the best and which tactic was better (offense vs. defense). Fortunately, the battle stopped when Team Rocket stole all of his fossil collection. Both father and son teamed up and defeated them. Byron then got to battle Ash, while Roark refereed, only for Ash to merge victorious.
- Byron's tactics are primarily defence tactics and his signature Pokémon, Bastiodon, is capable of blocking oncoming attacks. However, due to poor offense tactics, he loses to Ash. Byron has bad judgement of character as he compliments Team Rocket on digging holes well enough to not be villains. Fortunately, Roark tells his father that Team Rocket are bad as they stole Byron's fossil collection. He is one of the most popular Pokémon anime characters due to exclaiming how much he loves things (e.g., Bastiodon, Steelix, defense, fossils, digging holes).
- Candice (スズナ, Suzuna)
- Voiced by: Noriko Shitaya
- Candice is the Ice-type Gym Leader of Snowpoint City. Despite her title, very few challengers came to her hometown for a Gym battle. As a result, she works as a teacher at the Pokémon school for the most part. She is a childhood friend of Zoey and each had nicknames. Zoey calls Candice "Miss Senior" as they went to school together, while Candice calls Zoey, "Zo-Zo." She appears to be fond of the word, "kiai", and places it in sentences.

Candice greets Ash and friends when they arrived in Snowpoint City and asks Ash to help her class as Candice's assistant teacher.
- She is very excited about a challenger coming to her city and eagerly accepts Ash's Gym Challenge the next day, while Zoey and her friends watched. Candice's tactics consisted a barrage of close range physical attacks and defense strategies to overcome type disadvantages. Despite this, she loses to Ash. Shortly after Ash won, Paul showed up to challenge Candice. Unfortunately, as Ash had his Gym battle, Candice postponed it to a later day, which Paul accepts without question. She later watches Paul battle Brandon, where Paul loses due to letting his anger get the better of him. She has made a few cameo appearances watching Zoey and Dawn compete through various contests.
- Volkner (デンジ, Denji)
- Volkner is the Electric-type Gym Leader from Sunyshore City. In his early life, he spent it on mostly battling poachers and gangs on the streets. At some point, he met his rival, Flint, where they battled and later became friends following a victory against a Proprietor. While Flint became the member of the Sinnoh Elite Four, Volkner took on the job as Gym Leader. He is also an electronic engineer as he designed automated walkways, multiple solar panels and Sunyshore Tower which is in fact the city's power plant. Although a skilled battler, he grew disinterested in his victories and just gave away his Beacon Badges for free.
- Palmer mentioned that Volkner would give Ash "a shock" in battle, while Paul mentioned that the Gym was illegitimate, as Barry got his Beacon Badge without a proper battle. When Volkner refused to battle Ash, Ash decided to battle Flint in an exhibition battle. Because of Flint's victory, Volkner immediately decided to accept Ash's official Gym Challenge. However, the battle was interrupted, due to Team Rocket stealing the Sunyshore Tower. Both Ash and Volkner defeated Team Rocket with the help of Ash's newly evolved Torterra. Despite the success, the tower was badly damaged and Volkner had to repair it.
- Sometime later, after the Grand Festival, the heroes returned to Sunyshore City for the final Sinnoh Gym match. Volkner showed off his defense strategies and close range attack tactics in battle but finally loses to Ash when Ash's Infernape finally mastered its Blaze ability. With Ash's final win, Volkner and Flint congratulate Ash on his victory.
Unova Gym Leaders
The Unova region has a total of 11 gyms shown from both the Black and White games and Black 2 and White 2 games. With the exception of Drayden, Marlon and Cheren, Ash was able to defeat and earn eight Unova Gym badges out of the eleven gyms shown. For information on Cilan, see the main protagonists section. Iris is not listed there as she is not a Gym Leader, but a travelling companion and Unova Champion in the anime.
- Chili and Cress (ポッド, Poddo, コーン) Kōn
- Chili and Cress are Cilan's brothers. Cilan, Chili and Cress are triplets, waiters and own a restaurant that doubles as a Gym in Striaton City. When Ash arrived for his Gym Battle challenge, he is given the option to battle one of the three brothers (in the games, it is not optional, as the brother who specialises in the player Pokemon's weakness will be the one to battle the player). Ash decided to face all three of them and their Pokémon, Pansage, Pansear and Panpour, with two victories for one side as winner. Although Ash lost to Cress, Ash defeated both Chili and Cilan, earning his first Unova Gym Badge. Inspired by the battle, Cilan decided to travel with Ash while Chili and Cress had to take care of their gym.
- Sometime later, a C-class Connoisseuse named Burgundy attempted to challenge Cilan to a rematch, having lost to him. Upon learning that Cilan went travelling with Ash, Burgundy attempt to find Cilan for a rematch, only to lose again to him. It is revealed that Burgundy defeated Chili in a Gym Battle.
- Later when Ash, Cilan and Iris were at Driftveil City, Chili and his Pansear ran away from the Striaton Gym and met with Cilan. It is revealed that Chili has been losing a lot, due to using too much offense tactics and not enough defense tactics and all four of Pansear's Fire-type moves are not capable of covering its weakness against Water, Ground or Rock. Cilan taught Chili's Pansear a new move, Solar Beam to counter the weakness.
- After appearing in a few fantasy sequences and flashbacks, Chili and Cress appear one last time in the Decolore Islands arc. They had a nasty run in with Morana (Drago (ドラゴ)), an Ice-type trainer from Sinnoh and a dojo breaker. If the Gym Leader loses to her in a battle, then their Gym was hers. Although she defeated Chili and Cress, she had to face off against Cilan and tracked his whereabouts, with Cilan's brothers following as well. Cilan was able to defeat Morana and maintain the ownership of the Striaton Gym. Afterwards, Chili and Cress went home to Unova while Cilan, Iris and Ash head off to Kanto.
- Lenora (アロエ, Aloe)
- Voiced by: Atsuko Tanaka
- Lenora is a paleontologist and Normal-type Gym Leader from Nacrene City. She also works at the Nacrene Museum as a director, alongside her husband, Hawes, who is assistant director. Many trainers who attempted to challenge Lenora were required to search for a book that would help them out. Unknown to many challengers, she wanted them to find the book that will grant them access to the Gym battlefield. However, as many people wanted to find books they were interested in or can read through quickly, they failed her test before the battle could even begin.
- She first appears in the series stopping a rampaging Yamask who was trying to reclaim its lost mask. Once the ordeal was done, she then gave Ash the challenge to find a book that would help him become a better trainer. He does so and he gets to earn the right to face Lenora. Unlike most Gym Leaders, Lenora is allowed to switch her Pokémon out. Her tactic is to disorient her opponents using a combination of Roar from Lillipup in the first battle and Herdier in the rematch (which causes the opponent's Pokémon to switch out) and Watchog's Mean Look (which prevents the trainer from switching out their Pokémon). Because of this tactic, Ash ended up losing his battle to her.
- Sometime after training with Don George, Ash returns to the Gym for a rematch. This time, Ash was able to adapt to Lenora's disorientation tactic and successfully defeats her.
- Burgh (アーティ, Arti)
- Voiced by: Tōru Furuya
- Burgh is the Bug-type Gym Leader from Castelia City, a fashion designer and an artist.

In his debut appearance, Ash and friends encountered Burgh in Pinwheel Forest. He shows Ash how to interact with Bug-types when Ash was attempting to bond with a Sewaddle, which later became Ash's.
- Later, when the group met Burgh in his hometown, there was a Venipede infestation. Burgh was angry that the mayor of Castelia City planned to forcibly remove them. Burgh suggested to find the leader and heal the leader so that the Venipede could leave in peace. The Venipede were successfully drive out, with a help of Burgh's Bug Flute, and Ash and co.'s aid. Shortly after the ordeal, Professor Juniper arrived and Ash and friends decided to accompany her to the Desert Resort. This would have led to the Team Rocket vs. Team Plasma two-parter but the two episodes were cancelled due to the 2011 Tohoku Earthquake and the Fukushima Nuclear Disaster. The dub removed the reference to the Desert Resort and the episode ended with Ash looking forward to his Gym battle.

- Elesa (カミツレ, Kamitsure)
- Voiced by: Yumiko Kobayashi

Upon noticing Ash's Pikachu, she jumps off the runway and gets to meet the group up close, as she never seen a Pikachu before. Bianca first challenges Elesa but loses easily when Elesa's Zebstrika stomped all three of Bianca's Pokémon. Elesa and Ash also convinced Bianca's father to allow her to continue becoming a Pokemon trainer.
- Later, Ash gets to battle Elesa next. Despite a series of mishaps (trying to defeat all three of her Pokémon with just Palpitoad, bad type matchups (Ash's Snivy, a Grass type, against Elesa's Emolga, a Flying and Electric type), and not knowing the move, Attract, does not work on Pokémon of the same gender), Ash wins. Elesa does admit that she forgot that a strong bond between Pokémon and trainer is key to victories rather than dazzling and showing off to the crowd.
- Her Gym has a built in roller coaster that grants the challengers access to the battlefield. In addition, Elesa has multiple female fans watching her Gym battles, some of which cosplay as her.
- Clay (ヤーコン, Yacon)
- Voiced by: Tsuguo Mogami

Many years later, the mine would later become the Driftveil City Gym and also earned him the title, "King of the Mines."
- Clay first met Ash and co. briefly but could not battle Ash, due to work and a discovery of a new tunnel. The second time Ash tried to challenge Clay, he was turned down, but Clay sent Ash to a nearby island to get several sacks of Revival Herbs to make the Pokemon work healthily in the mines. He does accept Ash's challenge when Ash fulfills the request and thus earned the right for a Gym Challenge. Despite his efforts and head-on tactics, Clay loses the battle, but encourages Ash to continue on with his goal of becoming a Pokemon master.
- Skyla (フウロ, Fūro)
- Voiced by: Kana Ueda
- The Flying-type Gym Leader from Mistralton City, Skyla inherited the Gym from her grandfather, Miles (Mile (マイル)). While she was a skilled trainer, she had no time for other hobbies such as flying her plane, due to countless challengers coming to her gym. To resolve this problem, she created "Air Battles." The battles were more based on theory. If a challengers' Pokemon have positive type matchups, then they earn the badge without a proper battle. If not, then they do not earn the badge. She had been using it a lot, although it was highly disapproved of by Miles and Cilan. Cilan tried to challenge her into a battle to prove her air battles were wrong but loses, based on Skyla's predictions in terms of type matchup.
- Ash then challenged Skyla into a battle, which she accepts as the other challengers wanted to watch how an actual battle plays out. Although Skyla predicted that Ash would lose easily, she ends up losing due to Ash's newly evolved Unfezant and her own overconfidence. Afterwards, Skyla decided to drop the Air Battle habit and not take the battles too lightly.

- Roxie (ホミカ, Homika)
- Roxie is the Poison-type Gym Leader from Virbank City and the bass guitarist for her punk rock band, Koffing and the Toxics. Originally, Ash was going to go to Opelucid City for his eighth badge, but because the Gym was closed there, Ash went to Virbank City instead. Unlike in the games where she's the second Gym Leader, Roxie serves as Ash's final Unova Gym Leader to beat. Her Gym is a large concert hall where loud music plays affecting a trainer's concentration. One of the most dangerous tactics Roxie uses is to poison her opponents, regardless of type advantage, and had defeated multiple challengers with that tactic. Her Gym battles consists of Roxie using three Poison-types while the challenger is allowed to use all Pokemon on hand. Despite her poison tactics, she loses to Ash.
- Her Koffing was revealed to have been caught by Roxie when she hosted a concert in the Kanto region.

Fortunately, Iris and Excadrill were able to make amends.
- Ash originally planned on facing Drayden but he was away from his Gym, so he went somewhere else for his final Gym. He is one of the two Gym Leaders Ash never faces in battle (the other was Marlon).
- It is revealed that he is also the head of Opelucid Academy, the same school where Iris attended. Iris had a tough time there as she did not know how to fit in the school and was reprimanded by Drayden for not realizing she wore out a rented Fraxure during a practice battle. However, Drayden had faith in Iris as he plans on having her inherit the Opelucid Gym but after she goes on a journey first. He has a battle with Iris and wins again.

Once they arrived, Marlon battled Cameron. Despite using his strong Water-type Pokémon, offense tactics and the water arena to his advantage, Marlon lost to Cameron. As a result, Cameron has earned his final badge for his entry in the Unova League. Marlon is one of the two Gym Leaders Ash never faces as Ash already earned his eight Unova Gym Badges.
- Cheren (チェレン)
- Voiced by: Takuya Eguchi
- Cheren is the new Normal-type Gym Leader from Aspertia City. Unlike in the games, he is not a rival of Ash, and is already a teacher at the Pokémon school. He was first mentioned by Professor Juniper, who informed Ash and co. about the new Gym Leader, shortly after the Unova League.
- In his actual appearance, he helped the heroes to round up the School's Pokémon that ran out of control and wild due to Pikachu and Axew messing with the intercoms. He was able to calm down a scared Shinx despite getting electrocuted. Afterwards, he and Ash had an unofficial Gym battle match where Cheren merged victorious. He is the only Normal-type Gym Leader Ash never rematched, as Ash already earned his eight Unova badges and Cheren's badge is the Basic Badge, just like Lenora's.
Kalos Gym Leaders
The eight Kalos Gym Leaders are official members of the Kalos League. Unlike the previous series, all eight Gym Leaders banded together to help Ash and friends defeat Team Flare. For information on Clemont, see his information under main protagonists.
- Viola (ビオラ, Biora)
- Voiced by: Noriko Shitaya
- Viola is the Bug-type Gym Leader of Santalune City, a professional photographer and the younger sister of Alexa, the Kalos journalist Ash met during the Decolore Islands arc. Viola was first mentioned (though not by name) by Alexa in the last episode of the Black and White anime and was mentioned in the first XY episode, where she was away from her gym. She did not make an official appearance until Ash's arrival at Santalune City, where she photograph Ash and Pikachu near a fountain. When Ash attempted to battle her, he loses easily due to Viola's trap tactics (creating an icy field and Sticky Web traps) which counters both Pikachu and Fletchling's type advantage. Unbeknownst to Ash, Viola admitted to Alexa that she felt disappointed in Ash's performance. Alexa responds by warning Viola that there are no repeat performances in a rematch.
- When Ash goes back for a rematch, he was able to adapt to most of her tactics, but Viola's Vivillon knew Sleep Powder (which was never used in the first battle) to defeat Ash's Fletchling. During the Gym Battle rematch, Viola acts dismissive towards Ash, feeling that he had no chance of winning. Fortunately, with a bit of encouragement from Serena, Ash merged victorious, giving Viola a reality check. She reappeared in the Battle Chateau where she runs into Ash and pals and battles Grant, where she loses easily. She does make a few cameo appearances and teams up with Ash to help stop Team Flare. She seems to have feelings for Grant, which is reciprocated.
- Grant (ザクロ, Zakuro)
- Voiced by: Hirofumi Nojima
- Grant is a professional athlete, specifically in rock-climbing, as well as the Rock-type Gym Leader of Cyllage City. Ash first met him at the Battle Chateau, where he was able to defeat Viola and her Surskit. Afterwards, he heads back to his Gym, but not before telling Ash that he will wait for him at his Gym to battle. It appears that he has feelings for Viola, which is reciprocated.
- Later on, when Ash arrives in the Gym, Grant accepts his challenge. Grant's philosophy is that climbing walls is a way of letting a person reach enlightenment, as long as they focus on reaching the goal. This was demonstrated when Ash had to climb up the walls inside his Gym to reach the battlefield on the top, while Ash's friends took the elevator. For the battle, Ash is allowed to use all of his Pokémon on hand, while Grant has to use two. Although a strong battler and his Tyrunt took out two of Ash's Pokémon, he loses to Ash and Pikachu as Ash developed a counterstrategy against Grant's Rock Tomb and Draco Meteor attacks. Afterwards, before Ash heads off to Shalour City, Grant hoped to refight Ash at the Battle Chateau. This sadly never happened due to the writers rushing the XY series in order to coincide with the release of the Sun and Moon games. He has a few cameo appearances and helps Ash stop Team Flare.
- Korrina (コルニ, Koruni)
- Voiced by: Yuka Terasaki
- Korrina is the Shalour City Gym Leader, who specializes in Fighting-type Pokémon and rides around on roller skates. With the exception of Clemont, who's Ash's main Kalos companion, Korrina is also the only Kalos Gym Leader who briefly travelled with Ash and pals. Her main Pokémon is Lucario, who is capable of Mega-evolving. Within her debut series, she gets help from Ash and friends to search for a Lucarionite, a Mega-evolution stone for her Lucario, which they found successfully and they were able to Mega-evolve her Lucario. However, due to arrogance and failing to understand her Lucario being too battle obsessed (it is mentioned that they defeated 100 oppponents), her Mega-Lucario goes out of control and violently attacks his own allies. She had to go up to Pomace Mountain, where Mabel and her Mawile, capable of Mega-evolving, showed her how to be in sync through developing floral designs. Eventually, Korrina was able to master her Mega-evolution. Afterwards, she returned to Shalour City to prepare herself for the Gym Battle. Ash was able to defeat Korrina in a Gym battle with Pikachu defeating Mega-Lucario. She shows up in a few cameos and helped Ash defeat Team Flare.
- In Pokémon Journeys, Korrina was revealed to be competing in the Battle Festival to take a shot at facing Leon and reunites with Ash and meeting his Riolu. Although she was able to defeat Ash's Gengar with her Mienshao and somewhat adapt to Ash's tactics, it was not enough for her, as Ash defeats her Mienshao and her Mega-Lucario again with Dragonite. She was later mentioned by Bea in a later episode, where Bea reveals that she defeated Korrina off screen.
- Ramos (フクジ, Fukuji)
- Voiced by: Minoru Inaba
- Ramos is the Grass-type Gym Leader of Coumarine City. He owns a Grass-type Pokémon ranch and is a gardener. Despite his old age, he is very wise and provides Ash advice on how to deal with situations such as not to rush into problems and find the "side road" to solve the problems. His tactic is all about patience and uses a combination of defence tactics and sunlight to power up his Grass-types. He first met Ash and pals when they accidentally broke a fence in his ranch and helps them defeat Team Rocket when they abducted all three members of the Vanillite line. At the end of his debut episode, he reveals himself to be the Grass-type Gym Leader and was looking forward for his battle with Ash.
- He got to battle Ash after they enjoy some tea and do some gardening. Remembering what Ramos said about not to rush things during the gardening, Ash took this advice and was able to defeat Ramos in a Gym Battle. Ramos also appeared in the following episode when the city was having its annual Coumarine City Festival. He later made a few cameos and aids Ash in stopping Team Flare.
- Valerie (マーシュ, Mache)
- Valerie is the Fairy-type Gym Leader of Laverre City and a famous fashion designer who always wanted to be a Pokémon. Her Gym also operates as a fashion show and a fashion boutique which sells women's clothing with Pokemon patterns. The Furisode Girls serve as her employees not just for the fashion show but for gym battles. Serena is a huge fan of Valerie as she always wanted to meet her in person. In her debut appearance, Valerie was hosting a fashion show which meant that all Gym Battle requests were cancelled at the moment. When two of her models could not show up in time for the show, Valerie hired Serena and Bonnie as replacements. After the fashion show, she challenges Sawyer into a Gym battle and easily defeated him due to Sawyer's mistake of using a Dragon-type Bagon against her Fairy-type Spritzee. Unlike most Gym Leaders, Valerie does not meet Ash face to face until her second appearance, when Ash arrives to challenge her to a Gym battle. Although she puts up a good fight, she loses to Ash. She made a few cameo appearances since and shows up in the Team Flare arc where she helps Ash save Kalos.
- Her tactics primarily consist of using unexpected attacks and twisting the battlefield into her advantage, which she describes as "hidden fangs". Many trainers, prior to Ash, lost because of this strategy. She is also capable of speaking the Fairy-type Pokémon language. Valerie admires Ash as he mentions that he can understand how a Pokémon can feel, when she asked if he could talk to them as well during the Gym battle.
- Olympia (ゴジカ, Gojika)
- Voiced by: Masako Katsuki
- Olympia is the Psychic-type Gym Leader from Anistar City, as well as a Psychic mentor for her students. One of the unique traits was that she can see visions of the past (e.g., Ash's Frogadier's history) as well as the future (Team Flare arc), as well as having actual psychic powers. Tierno mentioned that he tried to battle her (who was not named at the time) for the Gym badge, but lost. In her debut appearance, she and one of her apprentices, Charlene, furiously stop and scold her other apprentice, Carrie, for attacking Professor Sycamore and his research crew, alongside Ash and pals due to Carrie misinterpreting the prophecy involving the main characters. Once everything was cleared up, Olympia reveals Ash's Frogadier past and what the future would hold for the two. She later engages in a Gym battle with Ash, using both her male and female Meowstic. Despite her tactics of using deadly move combinations (e.g., Helping Hand and Future Sight), Ash realized that Olympia was reusing the same attack combinations and, with careful timing, successfully defeated her.
- She briefly appeared later on in the show, informing Diantha about the upcoming disaster. Olympia later provides aid to Ash in stopping Team Flare. Her position as a Gym Leader is a reference to Tate and Liza as the twins were also the seventh Gym Leaders of their region, specialize in Psychic-types and have an official Double battle against Ash.
- Wulfric (ウルップ, Urup)
- Voiced by: Ryūzaburō Ōtomo
- Wulfric is a Ice-type gym leader from Snowbelle City. Ash first encounters him after Sawyer earned his final Gym badge for the Kalos League. While Ash puts up a good fight, he loses to Wulfric, as Ash was unable to master the Ash-Greninja technique. Wulfric explained that the loss was due to Ash having severe trust issues with his Greninja.
- Sometime later, Ash returned for his rematch after mastering the Ash-Greninja tactic and learning how to stop doubting himself in his Pokemon. This time, Wulfric loses to Ash, despite Mega-evolving his Abomasnow. He later helped Ash defeat Team Flare.
- Wulfric is very impatient and eager to battle, despite the referee being needed to explain the rules. He does have some speaking problems, usually starting sentences with, "You know what...". Like many Gym Leaders, he wants to see full potential in the challengers.
Galar Gym Leaders
The Gym Leaders of Galar. Unlike the previous series, Ash is not competing in the Galar Region.
- Bea (サイトウ, Saitou)
- Voiced by: Yoko Hikasa
- Bea is an expert of Galar Karate and a firece warrior of a Fighting Gym Leader, Bea is a determined fighter who rarely displays her emotions. She has an accurate sense of battle strategies and always remains calm even when facing a crisis. However, in spite of her calmness and tough looking exterior, Bea has a huge sweet tooth. While she tried to keep her love of sweets a secret, her fans eventually found out, which resulted in her having more trouble trying to indulge herself.
- Bea was considered as a prodigy in Galar Karate as mentioned by Chuck, the Cianwood Gym Leader, when he mentioned studying Galar Karate under her father when he visited Galar. Bea once had a battle against Korrina in which she came out victorious.
- Ash challenged her to a battle, once. Bea used Grapploct and Hawlucha, while Ash used Riolu and Farfetch'd. However, both of her Pokémon were undefeated and Bea came victorious. The coordination of their fighting stances, plus fast reflexes, and pure strength, makes her a devastating and brutal opponent.
- Bea was last spotted in Cianwood City, her rank rose to 193. Ash then demanded a rematch, to which Bea accepted. Bea kept her Grapploct, and switched Hawlucha for Hitmontop. Ash kept his Riolu, and switched Farfetch'd for Pikachu. After a tough battle, the match ended in a draw. Following the battle, Bea and her Pokémon surprised Ash and Goh who were shocked to see her eat the desserts offered by Chuck, she later states to Ash the next time they face each other will be in the Ultra Class.
- Although Bea has a stern exterior, she is actually a sweet person when she smiles, indicating that she can be outwardly nice to trusted ones. A speculation on why she rarely smiles is that her strict parents had posed an emotional burden on her during her childhood. It has also been stated that she lost her smile due to her parents' strict training. Additionally, it is implied that very few people have seen Bea smile, one of which is the player character following their Gym Battle with her.
- Opal (ポプラ, Popura)
- Voiced by Yoshino Otori
- In the past, Opal was a beautiful woman with black hair, fair skin, and a pretty nose. In the present day, however, Opal is now old, wrinkled, and has white hair.
- 70 years prior, Opal became the Gym Leader of Ballonlea, taking over from her mother. But now in her elderly years, she feels that she has reached her limits and decides to find herself an apprentice. To this end, her Gym Challenge takes the form of an audition. Though worthy challengers usually pass the battle parts to meet her in the stadium, Opal is also secretly judging their potential to become the next Ballonlea Gym Leader by the amount of "pink" they possess, based not only on appearance, personality or Pokémon, but by another personal standard that she never discloses outright. Her records backstage are filled to the brim with papers of challengers who got through the battle part but failed the audition, including those of Leon and Sonia, suggesting that she has been conducting this Gym Challenge format for a long time with no prospective candidate in sight.
- Opal loves seeing the color pink and will stop at nothing to find an apprentice. She can be rather forceful in that respect, since she will insist on having that person do what she wants regardless of their stand on the matter. She has a penchant of deliberately giving out tricky quizzes as well, claiming that they can make people reveal their true colors in a pinch. Many speculate however, that she does so merely out of spite.
Alola Island Kahunas

Voiced by (Japanese): Nobuyuki Hiyama
- Hala is the Kahuna of Melemele Island, who uses Fighting-types. Unlike in the games, Hala does not give the trainer a starter. He has been a Kahuna for a long time ever since Professor Kukui was a child. At some point prior to Ash's arrival to Alola, he mentored Kukui and Guzma before Guzma grew disillusioned and ran off vowing to become strong without Hala's teachings or Z-rings or Crystals. While carefree, Hala is also wise and provides advice to many people. It is revealed that Tapu Koko also took one of Hala's Z-rings to give to Ash to inspire him to take on the Island challenges. Hala also has grandson named Hau.
- Within his debut appearance, Ash needed to find a way to get rid of the Alolan Rattata and Alolan Raticate infestation without the use of violence. This leads to Ash's first Island trial where he had to defeat the Totem Yungoos and Gumshoos, in order to convince them to help drive out the Rattata and Raticate. Because of this accomplishment, Ash was granted his first Grand Trial. This is where Ash learns about how Z-moves work in battle as well as being warned about proper timing and how using a Z-move can drain a lot of energy. Taking Kukui's advice, Ash was able to easily win against Hala. Afterwards, Hala threw a big party for Ash on his first Grand Trial accomplishments.
- He has appeared frequently throughout later episodes since then such as participating in a Sled Jump Games while evolving his Crabrawler into a Crabominable, as well as appearing alongside the other Kahunas for the Alola League.

Once accomplished, Nanu accepts Ash's Grand Trial Challenge. Here, Ash had to defeat all three of Nanu's Pokémon using only his Lycanroc, which Ash succeeds. Afterwards, Nanu gives a Lycanium-Z crystal and does secretly admit to Acerola that he has some respect for Ash. He has made recurring appearances since then.

Despite this, he is a skilled battler using underhanded tactics such as mocking opponents as to bring out the best in challengers (a reference to Dark-types being known as Evil-types in Japan).
- Hapu (ハプウ, Hapu'u)
- Voiced by (English): Brittney Lee Hamilton
Voiced by (Japanese): Junko Takeuchi
- Hapu is the Kahuna of Poni Island, who specializes in Ground-types as well as working as a farmer. Originally, there used to be an Island Kahuna prior to Hapu, but he officially retired due to declining health. In addition, her deceased grandfather, Sofu, also was revealed to be a former Island Kahuna at the time. She first appeared in the Poni Island arc, where she falsely accused and attacked Ash and friends for stealing her radishes. Upon learning that Team Skull were the ones causing trouble, she drove them off and slowly starts to open up to the gang.
- After spending some time with the gang as well as battling Tapu Fini when the fog covered the island, her deceased grandfather returns as a ghost to inform Hapu that she is the next trainer to become an Island Kahuna. This is the first time where we get to see how an Island Kahuna Coronation works. She officially battled Ash in a Grand Island Trial but lost due to the mistake of giving Ash an environmental advantage. The battle arena the two fought on was surrounded by water which Ground-types could easily get soaked and left vulnerable to Electric attacks. Hapu has appeared alongside the other Kahunas frequently since then as well as giving Sophocles a Z-ring.
Kanto Frontier Brains
After Ash came back home from his Hoenn Journey, he meets Scott, the head of the Kanto Battle Frontier, who provides Ash the Battle Frontier Quest. There are a total of seven Frontier Brains, heads of their battle facilities across the Kanto region. The first six listed below are available to the challenger as they progress through the quest and earn a Frontier Symbol after winning, but the seventh Frontier area is not available until they defeat the first six Battle Frontiers. The Battle Frontier is heavily based on the ones the player faces in Hoenn in Pokémon Emerald. Unlike in the games, Ash only earns the Gold Symbols. In Journeys, Ash's Frontier plaque makes a cameo appearance and the Hoenn Battle Frontier area appears when Ash went to win the Battle Frontier Flute Cup Tournament.
- Noland (ダツラ, Datsura)
- Voiced by: Nobuyuki Hiyama
- Factory Head Noland is the owner of the Battle Factory. His battle is for the challenger to choose their own opponent they want Noland to use for the fight. He is also an inventor as he flies around on his airplane he built.
- In his debut appearance, Ash and the gang encounter him after one of his inventions goes out of control. He owns multiple Pokémon to randomize the battle types. He is also revealed to have befriended an Articuno, having mended its broken wing, but never caught it. After some consideration, Ash decided to face off against Articuno.
- Knowing that Articuno was going to be a difficult opponent, Ash summoned his Charizard from Charicific Valley to fight this Legendary Pokémon. Noland and Ash battled and after a long fight, Ash wins his first Frontier symbol. Noland also gave Ash a Frontier Pass called a "Frontier folio" to hold his symbols.
- Greta (コゴミ, Kogomi)
- Voiced by: Sanae Kobayashi
- Arena Tycoon Greta is the owner of the Battle Arena, which is a large karate dojo. She also is an instructor there and has multiple students training under her. She uses Fighting-type Pokémon for her battles in the anime. It is revealed that her two role models were Chuck and Brawly, the two Fighting-type Gym Leaders.
- Before the battle commences, the challenger has to spin a wheel to determine how many Pokémon both trainer and Frontier Brain get to use. As Ash landed on two, this meant it is a two on two battle. There are a couple of wedges which allowed both sides to use three Pokémon. However, as Ash only landed on the two wedge, nobody knows what Greta's third Pokémon is. Although Greta's Hariyama took out Ash's Grovyle, Ash used his Snorlax to take out her Hariyama and Medicham, despite a type disadvantage.
- Speed-based strategies are a terrible choice of tactic against Greta's team as she can use speed and physical moves to stop her opponents. However, attacks from behind or above her Pokémon are her weaknesses and they can also suffer damage if their moves missed.
- Tucker (ヒース, Heath)
- Voiced by: Kenta Miyake
- Dome Ace Tucker is the head of the Battle Dome and a famous actor. He loves to put on spectacular performances and has a large crowd watching his battles. His debut episode is where, for once, most of Ash's achievements are finally acknowledged. A challenger always has a press conference before the battle commences.
- His battle functions as a Double Battle where he uses Arcanine and Swampert against Ash's Swellow and Corphish. Tucker is shown to be a deadly battler where he uses a variety of move combinations, forcing Ash to create new attack combos. After a lengthy fight, Ash wins his third Frontier Symbol.
- Lucy (アザミ, Azami)
- Voiced by: Atsuko Tanaka
- Pike Queen Lucy is the head of the Battle Pike. Unlike in the games where she is cold and distant, she is quite a nice friendly woman, although she gets irritated if her assistants were rude to her guests. She is one of the few female characters to have romantic feelings for Brock.
- In her debut appearance, when her assistant, Barbara, was furious when Ash went to the Pike without greeting her and fellow associates (he was lured into a Team Rocket trap), Lucy comes in and tells Barbara off for her rude attitude. Lucy later helped Ash rescue Pikachu from Team Rocket and sent them flying using her own Seviper, which is way stronger than Jessie's. At first, the Pike was closed which meant Ash could not battle, but Lucy decides to accept the Frontier challenge (possibly because of her romantic feelings towards Brock). While she put up a good fight against Ash, she loses. Nevertheless, she does compliment on Ash for having good friends and having a great battle.
- Her tactic is all about offense and head on attacks but she never uses defense tactics. This was what led to her loss against Ash. She loves serpentine Pokémon, using them for battle, and those with squinty eyes she kept at home, just like Brock.
- Spenser (ウコン, Ukon)
- Voiced by: Nachi Nozawa
- Palace Maven Spenser is the head of the Battle Palace, a large temple in Metallica Island. Despite his old age, he is athletic which enables him to run around in the jungle. The entire island serves as a battlefield where both opponents need to maintain their pace and use the environments to their advantage. He also provides a snack break in the middle of the battle if everyone is getting exhausted.
- In his debut, he helped cured Ash's Pikachu with a natural remedy and later stopped Team Rocket from stealing Ash's Pikachu and Sceptile. The next day, both Spenser and Ash battled each other using the environments and weather conditions to their advantage. Ash was able to win with his Sceptile.
- Anabel (リラ, Lila)
- Voiced by: Akiko Kimura
- Salon Maiden Anabel is the head of the Battle Tower. Unlike in the games, she is the sixth Frontier Brain instead of the seventh (she switched positions with Brandon). She also uses Psychic-Type Pokémon in battles. She does not appear in the Sun and Moon anime which resulted in her role as an International Police Officer, like in the games, being completely omitted. Ever since she was a child, she had an empathetic ability which allowed her to communicate and understand a Pokémon's feelings.
- In her debut, Anabel comes across Ash, who was training for his match. After calming a wild Gyarados and some Beedrill, Anabel also stopped Team Rocket from stealing their Pokémon. While drying off at her place, everyone found out that Anabel was a girl. When Ash and friends arrived at the Battle Tower Salon, it turns out that Anabel was also a Frontier Brain. She defeats Ash easily in the match, putting an end to Ash's Frontier Brain winning streak.
- Later on, after training for a rematch, with a bit of help from Anabel, Ash merges victorious. With his six Frontier symbols, the Battle Pyramid is now available for Ash to fight. Unbeknownst to Ash, Anabel was revealed to have romantic feelings for him.
- She can telepathically give command by using only her mind. However, dark rooms are troublesome as she cannot see where her opponents are.
- Brandon (ジンダイ, Jindai)
- Voiced by: Masayuki Omoro
- Pyramid King Brandon is the head of the Battle Pyramid. In the games, he is the sixth Frontier Brain with Anabel as the final. In the anime, he is the seventh and final Frontier Brain who will not be able to challenge the trainers, until they defeated the first six Frontier Brains. His Pyramid flies around, which is why the location changes frequently and is initially unavailable. He works as an archaeologist, exploring various ruins and learning about their history.
- In his debut, the heroes encountered him while exploring a ruin. When Ash gets possessed by the evil spirit of King of Pokélantis, Brandon was forced to battle him using Regirock against Ash's Sceptile to free Ash. Afterwards, Brandon harshly explains that Ash was possessed due to his immaturity. Later on, Ash does battle Brandon, who acquire a Registeel during his ruin exploration. While Ash did lose the battle, Brandon knew Ash was on the right track and advised Ash to fight as one with his Pokémon before returning for a rematch. Hearing this, Ash calls in Squirtle, Charizard and Bulbasaur, for training and camping out for the final showdown. This time in the final battle, Brandon goes easy on Ash, using only Regice along with Solrock, Dusclops and Ninjask. After a hard fight, Ash finally wins the Battle Frontier Quest. Although accepted into the Hall of Fame, Ash turned down the position of Frontier Brain as he needs to explore more regions and develop his own skills. Brandon bids Ash farewell, hoping to see each other again.
- After a couple flashback appearances, Brandon returns in Diamond and Pearl. Shortly after Ash won his gym battle against Candice, Paul showed to battle her as well. Although his gym battle was scheduled for a later day, Paul encounters the Battle Pyramid which arrived in Snowpoint City as Brandon was going to explore the ruins there. Paul shows up and challenges Brandon into a full battle with both sides switching Pokémon. It is revealed in the past, Paul's older brother, Reggie, did try to battle Brandon while Paul watched when he began his own journey. Despite Reggie's efforts, he lost easily to Brandon due to having a lackluster strategy. As Reggie gets questioned with what his inner strength was, Paul wondered what his inner strength was as well and became a power-hungry jerk as a result. It was also due to the failure in winning at the Battle Pyramid was what caused Reggie to quit his career as a trainer and become a breeder. Paul's reason for battling Brandon was to avenge Reggie's loss while Paul believed that his true inner strength was his will. Brandon disagrees with this statement while questioning Paul's motives as a trainer. Despite his team having a type-advantage, Paul lost easily due to letting his anger get the better of him. Brandon harshly berates Paul for his attitude and tells him to fix it before coming back for a rematch. Shortly after, Brandon helps Ash and pals stop Pokémon Hunter J from stealing Regigigas from a temple. Although successful, Brandon stays behind to rebuild the temple and protect Regigigas. He is last mentioned when Paul reveals he is heading back to Snowpoint City for a rematch, while finally making peace with Ash.
- Brandon does not approve of foolishness such as calling out Ash for his arrogance, when the King of Pokélantis possessed Ash. Brandon believes that inner strength can be achieved through strong bonds between Trainer and Pokémon. He does not believe in brute force strategies as this was one of the reasons why Reggie and Paul lost to him.
Sinnoh Frontier Brains
In Diamond and Pearl, there was a Sinnoh Battle Frontier that was established and serves as a reference to Pokémon Platinum. However, Ash has not yet challenged the Sinnoh Frontier, as chances to do so was disregarded in favor of the Sinnoh League arc. This meant that Dahlia, Argenta, Thorton and Darach have yet to appear in the show. Caitlin, who is the co-owner of the Battle Castle, appears as a Unova Elite Four member, without any mention of her past as a Frontier Brain.

- He later hosted the Twinleaf battle Tournament, which not only meant that the Trainer will win the competition, they will also get to battle Palmer.

- Alder (アデク, Adeku)
- Alder was the Unova Champion when Ash was doing the Unova League quest. While laidback, reckless (such as stopping a rampaging Gigalith) and a womanizer, he does provide advice and acts as a role model to many trainers (primarily Ash). He seems to take some inspirations from Jiraiya from Naruto. Trip was a fan of Alder and strived to be a Champion like him.
- In his debut, Ash meets Alder in person and requests a battle with him, while running into Trip. Although Ash put up a fight, the battle was called off when it was revealed that Alder was sleeping. This angered his Bouffalant which caused it to headbutt him. As a result, Alder forfeited his match. Trip stared in disappointment at his former idol and stormed off in disgust upon learning that Alder stated that becoming the strongest was the not key to battle, contradicting the advice Alder gave to Trip earlier. Shortly after, he was able to stop a rampaging Gigalith by removing the nail that was stuck on one of its feet.
- Alder would not reappear until the Junior Cup where was hosting the tournament. When Trip won the tournament, he got the right to face off against Alder only to lose against him easily, due to the fact that Trip was very inexperienced in battle. Trip hoped to beat Alder someday, which Alder accepted.
- In the Journeys series, it is revealed that Iris became the new Unova Champion, confirming that Alder no longer holds the title. Because of this reveal, it is implied that Trip failed on his goal of defeating Alder.

Afterwards, she was taking a break from battles and meets Ash and co. while in disguise, while enjoying some delicious chocolate cake. Wanting to prove his worth to Diantha, he challenges her to a friendly battle which Diantha accepted. While battling, Team Rocket intervened and tried to steal Diantha's Mega Gardevoir only to fail miserably. The battle was shortly called off as her manager came to pick up Diantha.

- Diantha always remains calm in battle unless someone can put up a huge fight against her. She also has a sweet tooth as she enjoys sampling desserts when visiting new towns. Like many Champions, Elite Fours and Gym Leaders, Diantha does see a lot of potential in Ash.

- Voiced by: Hirotaka Suzuoki (Seasons 1-8); Kenta Miyake (Season 9+)
- Giovanni is the crime lord and leader of Team Rocket—having inherited his position from his mother—and the Viridian City Gym Leader. He is constantly frustrated by Ash's continuous interference along with his friends in his plans which they destroyed everything. Aside from the operations of Team Rocket, he also funded the creation of Mewtwo in Mewtwo Strikes Back. Mewtwo eventually escapes from him and he attempted to recapture the Pokémon in Mewtwo Returns—resulting in Mewtwo erasing all memories of himself from Giovanni's mind. Giovanni plays nearly the same role in the Pokémon Red, Blue, Yellow, FireRed and LeafGreen video games.[disputed ] He also appears in the Pokémon Adventures manga. Like in the anime, he organizes Mewtwo's creation. In the FireRed and LeafGreen chapters, he uses Red, Blue and Green to capture Deoxys and use it to find his son Silver.

- Meowth (ニャース, Nyāsu, Nyarth)
- Voiced by (English): Maddie Blaustein (4Kids); Jimmy Zoppi (TPCI)
Voiced by (Japanese): Inuko Inuyama
- Meowth fits in perfectly with his human comrades of Team Rocket as he is conniving, prideful, greedy and mischievous. His ability to speak like a normal human only makes him equally outspoken. He sometimes views himself as the boss and the leader of the trio, reason being, he builds all the contraptions and thinks of all the plans, though he is rarely taken seriously. For all his faults however, he is loyal to Jessie and James and never lets a few fights get in his way of being friends with them. He thinks highly of their boss Giovanni, and dwells on becoming his "top cat". Meowth is superb at lying, as he often tricks Ash and his friends to believe he is on their side. Pikachu is the only one who doubts Meowth's loyalty due to remembering his countless double crosses. Despite their rivalry, Meowth has arguably the most sociable moments with Pikachu, especially since they are often forced to team up for real. In some cases he laments they can easily be friends if not on opposite sides. As often as he likes to consider himself a dastardly villain, he is also often shown to be rather jaded and even philosophical at times. He often looks at the moon and laments his directions in life. Among the trio, Meowth tends to be the one who stands most on the facts rather than belief. Meowth frequently shows himself to be a rather amorous cat: in Kanto, before he met Jessie and James, he fell in love with a female Meowth named Meowzie, in Hoenn he fell in love with May's Skitty and in Sinnoh he fell in love with a female Glameow. In Unova he competed with Ash's Oshawott for both a male Purloin and Meloetta despite she was the main target for Team Rocket's Operation Tempest in the BW series until in the episode Unova Survival Crisis!. Also, in the short "Eevee and Friends" he also shown attraction for Espeon, Glaceon and Leafeon. His pursuits for Meowzie in particular chained off his ambitions to learn to speak and act human-like and ultimately his employment within Team Rocket. Meowth sparsely battles, he explains learning to walk and talk came at the expense of his battle abilities. As such, most instances he is forced to fight prove pitiful. On rare occasions however, when passionate or incensed enough, Meowth can be very formidable in battle. He has also proven quite able as a performer as well, helping Jessie win several contests and showcases. More commonly, Meowth acts as a translator for Team Rocket and sometimes Ash and his friends, translating what other Pokémon are saying. Meowth is jealous of Giovanni's Persian and has a desire to fill in for it as the boss's "top cat". In "Acting True to Form!", Meowth has a bitter rivalry with an Alolan Meowth who is very smart and cunning and also loyal to Jessie and James. Upon hearing that the Alolan Meowth was now working with Team Rocket later owned by their secretary Matori, he became disappointed to hear when he translated its language about its main reason to stay at their headquarters. He also fell in love with the Ultra Beast Pheromosa due to its feminine like appearance.

Voiced by (Japanese): Yūji Ueda
- Wobbuffet is used occasionally for battles, and now he joins Team Rocket. Wobbuffet's knowledge of moves like Counter and Mirror Coat comes in handy, since Team Rocket often find themselves on the receiving end of powerful attacks. Wobbuffet usually serves as a comic relief character due to his goofy, energetic, and looney character. He emerges from his Poké Ball frequently as a running gag, and often at inappropriate times which frustrated Jessie at times. Team Rocket has also had various vehicles and robots based on him.

In "Fight for the Meteorite!", Shelly leads a squad of Aqua grunts on a mission to Mt. Chimney, to try to steal a meteorite from Professor Cozmo before Team Magma could do so. Though they do not obtain the meteorite, Shelly still considers the mission a success, since the meteorite is destroyed and therefore Team Magma could not use it either. She appears again in "Unfair Weather Friends", where she and a group of Aqua grunts take the staff of the Weather Institute hostage in order to obtain their data on Groudon and Kyogre. However, their plans are thwarted by Magma agent Brodie, who makes off with the data himself. Shelly's final appearance is in "Gaining Groudon" and "The Scuffle of Legends".

- Voiced by: Nina Kumagaya
- Casey is a Pokémon Trainer from New Bark Town in Johto. Being a fan of the Electabuzz baseball team, Casey likes yellow Pokémon with stripes. Ash belittled her team, claiming it was weak, making Casey furious to challenge him to a battle, which Ash wins. Team Rocket deceives Casey into battling Ash once more, claiming that his use of Charizard broke the rules. Team Rocket takes the opportunity to catch Chikorita and Pikachu, which makes Casey realize they fooled her. Ash and Casey defeat Team Rocket. Later, during the Bug Contest, Ash warns Casey she was pushing Chikorita too hard, though Casey ignores Ash. When Chikorita runs away, Misty scolds Casey, reminding her it is important to look after the Pokémon, rather than winning the Contest. Casey apologizes for pushing Chikorita so hard. Team Rocket arrives and kidnapped Ash and Pikachu. Casey let Chikorita know she is with it, which makes Chikorita evolve into a Bayleef to beat Team Rocket again and free Ash and Pikachu. After the Contest ends, Casey, who did not win, felt like a winner for having Bayleef on her side. Knowing that Casey loves yellow Pokémon with stripes, Ash gives away the Beedrill he caught in the Contest to Casey. Casey meets up with Ash and his friends again, with the help of her evolved Meganium catches another yellow striped Pokémon, Elekid.

- Butler (バトラー, Batorā)
- Voiced by: Kenji Nojima (young), Kōichi Yamadera
- A former scientist of Team Magma and a magician, Butler was fired from working with Team Magma because an experiment to create a Groudon from a fossilized remnant of it had failed. Fueled by bitterness, hatred and an extreme thirst for revenge, Butler assembles a plan for alternative ways of creating a Groudon from scratch. He realizes that he needs a stronger energy source for the regeneration process. The power that he seeks is only available once in a millennium. Butler and his girlfriend, Diane, find the crystallized "cocoon" of Jirachi in Forina. When Ash, Brock, May and Max find Butler at the Millennium Festival, Butler presents Jirachi to Max because Max is supposedly the friend that Jirachi needs to find so it can awaken when the Millennium Comet comes. Butler uses Jirachi's power in the hopes to create a Groudon from scratch. However, he ends up with a manifestation of pure evil that resembles Groudon. When the false Groudon starts sucking up every Pokémon in sight, Butler begs Ash and Max to forgive him and help him to set his machine in reverse to get rid of Groudon. The plan is a success and the false Groudon is destroyed.
