The protagonist of the video games can be renamed by the player, but each has an array of default names.

This design was ultimately used for the character Blue (Blue (ブルー Buru)) in the Pokémon Adventures manga. While no name is officially given to the character, many refer to her as "Leaf" (リーフ Rīfu), which is one of the many pre-set options available for the female avatar.

The main character's rival in the video games has a number of different names, but he roughly corresponds to several other characters in the animated series and comics. (Note that not all of the corresponding characters are rivals or antagonists to the protagonist in the anime or in Pokémon Adventures, however.) In the Pokémon video games, the rivals will always pick a starter Pokémon which has a type advantage over the player's own.
- Blue (Green (グリーン Gurīn)): The player's rival and League Champion in Pokémon Red, Blue, Yellow, FireRed, and LeafGreen. He is pushy and competitive, but is generally a good Pokémon Trainer. He is the grandson of Professor Oak. Blue is the basis for Gary Oak in the anime and Blue in Pokémon Adventures. IGN listed Blue as the 98th best villain in video games, though they stressed that it was difficult to view him as a villain. However, they did say that he was kind of a "douche", citing his attempt to prevent the player character from getting a map. Three years later in the generation 2 games and their remakes, he becomes a Gym Leader for Viridian City, where he is the final gym in the post-game, before gaining access to Mt. Silver to fight Red.
- Silver (シルバー Shirubā): The player's rival in Pokémon Gold, Silver, and Crystal, and their remakes, Pokémon HeartGold and SoulSilver. This character steals his first Pokémon from Professor Elm, and tends to see Pokémon as tools, to use and discard, although not in Pokémon Adventures. Unlike the first rival, his view on Pokémon makes him a mediocre trainer, though the sage in the Sprout Tower recognises that he is talented, and has great potential. In HeartGold and SoulSilver, if the player brings an event Celebi to the Ilex Forest shrine, Silver is revealed to be the son of Team Rocket Boss Giovanni, and his hatred of Team Rocket stems from his father's failure. He eventually realizes his wrongdoings and changes his ways by treating his Pokémon and even the player with respect. This rival does not appear in the anime mainly, but is featured in the Japanese opening for Pokémon Chronicles. It is unknown if Giovanni is the father of Silver in the anime timeline, just like his game and Pokémon Adventures counterpart.
- Wally (Mitsuru (ミツル)): Another one of the rivals in Pokémon Ruby, Sapphire, and Emerald is the player's protégé, Wally. In the beginning, he is a sickly young boy who needs help in catching a Pokémon. When he goes to the player's father for advice, Norman directs the player to help him catch a Pokémon. Using Norman's Zigzagoon, the player helps Wally catch a Ralts. The next time he battles the protagonist, he seems healthier and is in tune with his Pokémon. He battles the player for the last official time at the end of Victory Road and waits there, always ready for another battle.
- Barry (Jun (ジュン)): Barry is the player's rival in Pokémon Diamond, Pearl, and Platinum. He is often impatient and is determined to be the best Trainer of all time. He is best friends with the player, and his father, Palmer, owns the Battle Tower in Sinnoh. Sometimes he will aid the player. He tends to accidentally crash into people quite often as he runs about. He can be fought again during weekends at the Fight Area. In the anime, Barry genuinely loves Pokémon, and is disgusted at how Team Galactic exploit Pokémon for profit. He is the basis for the character Pearl (パール Pāru) in the Pokémon Adventures manga.
- Cheren (チェレン): One of the rivals in Pokémon Black and White. Cheren is very intelligent and trustworthy; he often gives the player character advice and battles the player to test his skills. Like the player, he aims to become the Champion. He is one of the player's childhood friends. Two years later, in Black 2 and White 2, he becomes Aspertia City's Gym Leader, giving the Basic Badge to trainers who have defeated him. If the player used the Memory Link function in Black 2 and White 2, he challenges the player using his final team from Black and White. His name is from the Bulgarian word for black: черен (cheren).
- Bianca (Bel (ベル Beru)): One of the rivals in Pokémon Black and White. Bianca is spontaneous and sometimes unreliable, but she develops over the course of the journey. She also has a strong side, which she shows when she goes on a Pokémon journey against her father's wishes. She is one of the player's childhood friends. Two years later in the events of Black 2 and White 2, Bianca becomes an assistant to Professor Juniper and is the one who gives the player their starter Pokémon. If the player used the Memory Link function in Black 2 and White 2, she challenges the player using her final team from Black and White. Bianca is unique among the player's rivals in which she picks a starter Pokémon with a type disadvantage to the player's own, rather than a type advantage. Bianca's name is from the Italian word for white, while her Japanese name "Bel" has the same meaning from Russian: бел (bel).
- N (エヌ Enu): N is one of the rivals and antagonists in Pokémon Black and White. He is a very mysterious trainer who shows up at random and inconvenient times and believes that all humans and Pokémon should be separated. He is almost always seen using Pokémon that can only be found in the area that he is fought in. He is later revealed to be the 'king' of Team Plasma. He was forced to grow up with abused Pokémon, as a plot by his adoptive father, Ghetsis, so that he would want to liberate all Pokémon from humans. By following through with the plan, he captures either Zekrom or Reshiram (depending on the game version) in order to show the world his power so that they will follow through with his plan to liberate all Pokémon. N returns in Black 2 and White 2 in a supporting role, enabling the games' mascot Kyurem to transform into its iconic form for the game version. In the end game, N can be challenged, using his legendary Pokémon from the previous game, and upon defeat the Dragon transforms into a Key Item the player can use to capture the Dragon himself or herself. After another in-game event, N becomes a character the player can challenge on a monthly basis, with the team changing with the games' seasonal cycle. His full name is Natural Harmonia Gropius (ナチュラル・ハルモニア・グロピウス Nachuraru Harumonia Guropiusu).
- Hugh (ヒュウ Hyū): Hugh is the player's rival in Black 2 and White 2. He is from Aspertia City, like the player characters, and is also seeking to become a Pokémon Master. Throughout the game, the player helps Hugh retrieve his sister's Purrloin which was stolen by Team Plasma. "Hugh" is the default name option, but the player can pick a custom name.

During several points in the game, the rival will battle the player.
- Lucas or Dawn: The pseudo-rival in Pokémon Diamond, Pearl, and Platinum is either Lucas or Dawn. They are the opposite gender of the player's character and are one of Professor Rowan's assistants.

The rival has a little sister in Sandgem Town that watches TV and tells the player where swarms of Pokémon come.
- Ethan or Lyra: The pseudo-rival in Pokémon HeartGold and SoulSilver is either Ethan or Lyra. They are the opposite gender of the player's character, and are the grandchild of the daycare couple on Route 34.

- Shauna (サナ Sana): Shauna is a friend of the player character in X and Y from his/her hometown Vaniville Town. She is energetic and curious about the Kalos Region, but still does not know what she wants to gain from her experiences. She gives the player character a nickname at the outset of their journey. She is available as a Multi Battle partner at the Battle Maison.
- Tierno (ティエルノ Tieruno): Tierno is another friend of the player character in X and Y from Snowbelle City. He is more interested in finding new Pokémon to make a perfect Pokémon Dance Team and gets distracted in battle: as a consequence, he tends to be the weakest trainer out of the five. He is available as a Multi Battle partner at the Battle Maison.
- Trevor (トロバ Toroba): Trevor is another friend of the player character in X and Y who hails from Lumiose City. He is studious and wishes to fill up all three parts of the Kalos Region's Pokédex. He is available as a Multi Battle partner at the Battle Maison.
The Pokémon League is a little-described organization that organizes and certifies Pokémon Gyms and Pokémon tournaments. Becoming the Pokémon League Champion is one of the main goals in the video games, as well as one of Ash's stated goals in life in the anime.
The members of the Pokémon League have differing roles depending on where they appear; in the video games, they are the one-time "boss" opponents the player has to overcome to progress through the game, in the anime, they are usually one-time challengers Ash has to face to become the Pokémon League Champion, and in the manga, they are alternately enemies or allies to the protagonists, depending on their individual motivations.
Gym Leaders (ジムリーダー Jimu Rīdā) lead Pokémon Gyms, and offer Gym badges to Pokémon trainers who can defeat them. Usually, this challenge takes the form of a Pokémon battle, but, occasionally, the challenges are a trial of skill or endurance, or the badges are given in return for extraordinary services rendered.
Each main region has at least eight Gym Leaders at a time. Any trainer who earns a Gym Badge from eight Gyms is eligible to go on to face the Elite Four or participate in the Pokémon League Championships, as appropriate.
Kanto Gym Leaders
- Brock (Takeshi (タケシ)): Gym Leader of Pewter City and an expert on Rock-type Pokémon. In the Pokémon anime, he joins Ash on his adventure, leaving his post to his father, Flint.

- Lt. Surge (Matis (マチス Machisu)): An expert in Electric-type Pokémon. He is ex-military, but retains the lieutenant title, at the Vermilion City gym. Unlike the majority of the characters in the game, Surge is American born, rather than being a native to Kanto. In the Japanese versions of the games, he speaks in broken Japanese, with many of his words parsed in katakana, and therefore English. In the Pokémon Black 2 and White 2, a man who describes all of the World Leaders questions if Lt. Surge is from Unova. This is probably because Lt. Surge is from America, and the Unova region is based on New York City, USA. It is also mentioned in Unova's history that they have been at war, which Lt. Surge also mentions in the Generation I games and their remakes.
- Erika (エリカ): An expert in Grass-type Pokémon. Operates a women-only Pokémon Gym (which doubles as a greenhouse) in Celadon City. In the anime, Erika also works as a perfume maker. In Pokémon Adventures, Erika serves as the leader of the Kanto Gym Leaders who are unaffiliated with Team Rocket.

In the anime, she is a cold, emotionless woman born with powerful psychic abilities, including telekinesis, telepathy, and transmutation, which she used in destructive ways as a child.

In the video games, she is still a psychic, but she is not portrayed as evil. The protagonist is told of how she beat the leader of "The Fighting Dojo" (the gym next door) by robbing it of its gym status. Sabrina returns in Black 2 and White 2 in the Pokéstar Studios mini games as a movie villain.
- Kiyo (Nobuhiko (ノブヒコ)): Kiyo leads a martial arts gym in Saffron City, and, until an unspecified amount of time before the events of Pokémon Red, Blue, Green, Yellow, FireRed, and LeafGreen, was either a Gym Leader or an aspiring Gym Leader. Either way, his prospects as a Gym Leader were dashed after Sabrina and her Gym of Psychic-type Pokémon defeated him and his followers. In Red, Blue, Green, and Yellow, is he simply called by his trainer class, Blackbelt (Karate King (からておう Karate Ō)), and is in FireRed and LeafGreen erroneusly called Koichi (Takenori (タケノリ)) due to an oversight.
- Koga (Kyō (キョウ)): An expert on Poison-type Pokémon, a ninja who also patrols the Safari Zone in Fuchsia City. Runs the Fuchsia City Gym in Pokémon Red, Blue, Green, Yellow, FireRed and LeafGreen.

- Janine (Anzu (アンズ)): An expert in Poison-type Pokémon. Janine is Koga's daughter, and in Pokémon Gold and Silver takes over the Fuchsia City Pokémon Gym after her father joins the Elite Four. She makes the Gym's invisible maze even more confusing by filling it with lesser Pokémon trainers disguised as herself, to mislead challengers.
- Blue (the player's rival in the first generation games and their remakes) becomes the new Viridian City Gym Leader following the disappearance of Giovanni in Pokémon Gold, Silver, and Crystal, and their remakes, Pokémon HeartGold and SoulSilver. He does not stick to a specific type and has a wide variety of Pokémon, similar to the team he would have at the end of the preceding games.

They desire to reshape time and space to their preferred designs by making a red chain to control Dialga and Palkia. They attempt create a new universe, kidnapping Uxie, Mesprit, and Azelf for their plans. In the video games, they appear to only want Dialga in Diamond or they only want Palkia in Pearl. In Pokémon Platinum, they want both but are stopped when Giratina comes out of the Distortion World and drags everything back in with it. In the anime series, They are almost successful in creating a new universe, but are stopped when Ash and his friends destroy the red chains, forcing Cyrus to step into the "new universe" as it collapses. Later, Looker arrests Mars, Jupiter, Saturn, and Charon, causing Mars to exclaim that "... this is the end of Team Galactic."
- Cyrus (Akagi (アカギ)): The leader of Team Galactic. Although it appears he wants to work with his team to create a new universe, he really wants to create the universe solely for himself, making it one devoid of emotions that he sees as weak and useless.
- Mars (マーズ Māzu): One of Team Galactic's commanders. She leads the group's actions at the Valley Windworks and also the assault at Lake Verity. In Platinum, she displays a dislike towards Charon and quits Team Galactic afterwards, looking to save Cyrus from the Distortion World.

Team Plasma (プラズマ団 Purazuma-dan) is the antagonistic group in Pokémon Black and White who seeks to separate Pokémon from humans. They are led by a boy known only as N and the Seven Sages who will capture Reshiram in White and Zekrom in Black (the player will capture the opposite colored one), intending to use the Dragon Pokémon to force people to abandon capturing Pokémon. In reality, N is a pawn used by his adoptive father Ghetsis, one of the Seven Sages, who raised him for the sole purpose of being able to tame the legendary Pokémon and then disposing of him, so that he can take control of Unova. Two years after Ghetsis's defeat and N's departure from Unova, Team Plasma reforms itself with its true intentions at the forefront, intending to use the power of Kyurem to take over the Unova Region and the rest of the world.
- Ghetsis (G-Cis (ゲーチス Gēchisu)): Ghetsis is the true leader of Team Plasma, and N's father, having raised the boy to serve as a charismatic leader while secretly running the true operations of the group behind the boy's back. For much of Black and White, he presents himself as a seemingly benevolent, well-meaning figure, but is steadily hinted at - and ultimately revealed as - the main villain of both sets of games and the main antagonist, rather than N. When N was only a child, Ghetsis kept him away from humans and closer to abused Pokémon, so that he would later develop resentment against humans who live side-by-side with their Pokémon and not realise how many good people actually existed. Because of this, Ghetsis was able to easily manipulate N into believing that he would be the "hero" that would help free all the Pokémon world from their owners. Afterwards, it is implied that Ghetsis planned to get rid of N once he had accomplished his mission: becoming the sole controller of Unova's Pokémon. However, the actions of the player - who has helped inspire N to see beyond his old views - lead to N's defeat. This infuriates Ghetsis, who reveals his true colors and attempts to stop the player himself. After his defeat he begins losing his mind, but retains enough clarity to escape with the help of his loyal servants, the Shadow Triad. In Pokémon Black 2 and White 2, Ghetsis returns as the new leader of Team Plasma. When met, he will state that Kyurem is an empty shell, and that he will pour his ambitions into that shell. In Giant Chasm, he will command Kyurem to freeze the player alive with the Pokémon's signature move, Glaciate, but will be stopped by N. Unfortunately, he predicted that N's love for Pokémon will lead him to Kyurem and then merges Kyurem and Zekrom (Black 2) or Reshiram (White 2) to create Black Kyurem (Black 2) or White Kyurem (White 2), respectively. After Black/White Kyurem is defeated, Ghetsis then challenges the player to a battle. After losing, he loses the last of his sanity and the Shadow Triad move him away - later revealing that his mind has completely broken from the shock of his failures. His full name is Ghetsis Harmonia (ゲーチス・ハルモニア Gēēchisu Harumonia, G-Cis Harmonia in Japanese).
- The Seven Sages (七賢人 Shichi Kenjin): The high-ranking members of Team Plasma. Throughout the course of the gameplay, the player encounters each of the sages but will not be able to battle them. After the defeat of N and before becoming the Pokémon Champion, the player must locate all of the Sages scattered throughout the Unova region. Ghetsis is the leader of the Seven Sages. The other Sages consist of:
- Zinzolin (Vio (ヴィオ)): Associated with the color purple. He returns in Pokémon Black 2 and White 2 under Ghetsis' Team Plasma, and battles the player at several points in the game. He is a specialist in Ice-type Pokémon, which is odd for someone who does not like the cold.
- Ryoku (Ryokushi (リョクシ)): Associated with the color green.
- Giallo (ジャロ Jaro): Associated with the color yellow.
- Rood (Rot (ロット Rotto)): Associated with the color red. He returns in Pokémon Black 2 and White 2 as part of the old Team Plasma, and is battled at their warehouse in Driftveil City. He seems to specialize in the Normal Type. He entrusts N's Zorua into the player's care, and assists the player at the Giant Chasm against Ghetsis' faction.
- Bronius (Sumura (スムラ)): Associated with the color brown.
- Gorm (Asura (アスラ)): Associated with the color blue.
- The Shadow Triad ("Dark Trinity" (ダークトリニティ Dāku Toriniti)): Three ninja-like young men who are Ghetsis's faithful servants because he once saved their lives. They have the ability to teleport, and usually "escort" the player to N or Ghetsis. After Ghetsis's defeat and arrest (and later unexplained break-out), the Shadow Triad appears one last time on the Marvelous Bridge, where they explain that Ghetsis ordered them to bring the player the 3 Orbs of Dialga, Palkia and Giratina (Adamant, Lustrous and Griseous, respectively) and that despite their loyalty to him, he has ordered them to not look for him. The Shadow Triad were once rumored to be the Striaton City Gym Leaders Cilan, Cress, and Chili. The Shadow Triad returns in Pokémon Black 2 and White 2, and battles the player several times in the game. They are also revealed to possess a Liepard which had evolved from a Purrloin which was stolen from the rival character's younger sister five years earlier, leading him to foster a deep hatred for the organization. At first, this includes Rood's faction as well. After Team Plasma disbands, the Triad remains at Icirrus City, where they can be challenged on a monthly basis. Using the Unova Link Function unlocks a cutscene involving Cilan, Chili, and Cress fighting against The Shadow Triad (and losing) - thus disbanding the rumors that the two groups are one in the same.
- Anthea (the Goddess of Love (愛の女神 Ai no Megami)) and Concordia (the Goddess of Peace (平和の女神 Heiwa no Megami)): Two characters who appear towards the end of the main story of Black and White who serve N. Concordia tells the player the story of N and how Ghetsis raised him, while Anthea heals the player's Pokémon in preparation for the final battle against N. They can also be seen in the game's first opening sequence where they watch as N is crowned as the king of Team Plasma by Ghetsis. It was revealed that Anthea and Concordia are N's foster Sisters. They appear in Black 2 and White 2 in Rood's Pokémon volunteer house in Driftveil City, where they tell the player of Ghetsis' ambitions and what he did to further them, as well as N's early childhood before Ghetsis found him. According to them, N had spent this part of his life in a forest with a Darmanitan and a Zorua (the latter of which can be acquired from Rood) as he had distressed people with an unusual ability to commune with Pokémon.
- Colress (Achroma (アクロマ Akuroma)): Colress is an independent Pokémon researcher in Black 2 and White 2, who works to learn about the powers of Pokémon and tries to bring out the true strength within them. He battles the player several times throughout the game to test the player's ability and the power of the player's Pokémon. He eventually aligns with Team Plasma, as they will allow him to study Pokémon the way he wishes. After Team Plasma is defeated, again, he helps the group reform their ways. He can then be battled at the P2 Laboratory. He has a larger antagonistic role in the anime, as he is building a device that would allow Ghetsis to control Reshiram, and he takes control of various Pokémon, including Team Rocket's Meowth, in an effort to fine tune it.
Team Flare (フレア団 Furea-dan) is the evil team appearing in Pokémon X and Y. Their main goal is to "create a beautiful world", which eventually manifests itself into mass genocide of all human and Pokémon life but themselves, using an ancient weapon once used by a king of Kalos, an ancestor of their leader Lysandre, from 3000 years ago. While their plan involved harnessing the power of Xerneas and Yveltal depending the game's version, Team Flare's scheme in the anime involves controlling Zygarde and the sundial as their weapon of holocaust
- Lysandre (Fleur-de-Lis (フラダリ Furadari)): The leader of Team Flare, seeking to attain eternal beauty. He follows the player's progress closely, seeking the player in his plans, and revealing the history of Kalos and the king AZ, his ancestor, who nearly wiped out all life. After his identity as Team Flare's leader is revealed, he admits that he wishes to use his ancestor's weapon to enact a mass Pokémon extinction, believing the Mega Ring to be central to his plans. The player ultimately defeats Lysandre, and when Lysandre attempts to activate the weapon, despite the player having captured its power source Xerneas (X)/Yveltal (Y), the weapon crumbles and destroys the headquarters. Although the player and his/her friends, as well as most of the members of Team Flare, manage to escape, Lysandre is never seen escaping the destruction, therefore he is presumed dead. In the anime, using Lysandre Labs as a front, Lysandre manipulates Alain to provide him with Mega Evolution while his subordinates managed to capture the blue-core Zygarde in his plan to control both Zygarde Cores while destroying Lumoise City as a display of Team Flare's power. But after losing to Ash, Alain, and a redeemed Malva, as well as losing both Zygarde Cores, Lysandre resorts to using a Zygarde fabrication created from the Megalith and have it absorb the energies of the Anistar sundial to invoke an global genocide. But the Zygarde Cores assume their 100% form to destroy the fabrication, with Lysandre seemingly killed in the process.

- Lusamine: The leader of the Aether Foundation, the mother of Lillie and Gladion, and the real villain of Sun and Moon. She is obsessed with the Ultra Beasts, specifically the Nihilego species having fallen under their influence; Gladion speculates her fixation started after her husband vanished while studying them. She went as far as unleashing them upon Alola before eventually turning herself into one at the games' climax (making her the only villain in the franchise whose final battle is fought against a mutant version of themselves). While she is now living in Kanto to have the last of the Nihilego poison removed from her and trying to rebuild her relationship with Lillie, her ultimate fate in the original games remains unknown. However it is implied that she is now wanted by the International Police for her actions against Alola whilst she was possessed.

The Pokémon Professors give new Pokémon trainers a starting Pokémon appropriate to their region, and entrust them with a task (be it completing a Pokédex, delivering an object, or otherwise offering encouragement). They are also leading researchers of Pokémon-related topics, and mentor Pokémon trainers in a general way. It's interesting to note that almost all Pokémon Professors are named after trees: Oak, Ivy, Elm, Birch, Rowan, Juniper, and Sycamore, with the exception of Professor Hastings.
- Professor Samuel Oak (Professor Yukinari Ōkido (オーキド・ユキナリ博士 Ōkido Yukinari-hakase)): A Pokémon researcher and the grandfather of Blue/the rival in Pokémon Red, Blue, Yellow, FireRed, and LeafGreen. He is often considered the leading Pokémon expert, often giving lectures to Pokémon academies and hosting a radio show in Goldenrod City, and specializes in Pokémon behaviorial science. Alongside his research, he is also authorized by the Pokémon League to give new Pokémon trainers one of the three Kanto starter Pokémon: Bulbasaur, Squirtle, and Charmander. In the anime, he gives Ash his Pikachu after Ash arrives too late to receive one of the usual three starter Pokémon. In Pokémon Yellow: Special Pikachu Edition, he simply gives the player a Pikachu after the rival takes the Eevee that Oak intended to give the player. He is a master Pokémon poet. All Pokémon he "baby-sits" are loyal to him, and he had a Charmeleon as a young boy. In Pokémon 4Ever, it is shown that he traveled forward in time to the future when he was a boy, and Ash became friends with him. When Ash tells Professor Oak about him, he replies that he is sure that "Sammy" will always be his friend, even though Misty later realizes that Ash never told him his name; the current Professor Oak is later seen looking through a book of old drawings he made as a kid (the predecessor to the Pokédex, which he invented with the other professors).
- Professor Felina Ivy (Professor Uchikido (ウチキド博士 Uchikido-Hakase)): A Pokémon researcher. She is the leading researcher in the Orange Islands.

- Professor Elm (Professor Utsugi (ウツギ博士 Utsugi-hakase)): An absent-minded Pokémon researcher, and former student of Professor Oak. In Pokémon Gold, Silver, and Crystal, he is authorized by the Pokémon League to give new Pokémon trainers one of the three Johto starter Pokémon: Chikorita, Cyndaquil, and Totodile. He is also credited as discovering that Pikachu is an evolved Pokémon. In the Pokémon anime, Jessie, James and Meowth temporarily steal a Totodile from him, (in reality he tells them to take it, thinking they are Nurse Joy). His 'absent minded professor' stereotype is even more pronounced in the games as he often forgets to visit his family and his wife worries that he may not remember to eat. He specializes in research regarding Pokémon breeding and is credited with the discovery of Pokémon eggs.
- Professor Birch (Professor Odamaki (オダマキ博士 Odamaki-hakase)): A Pokémon researcher, known for his fieldwork and research on Pokémon habitial distribution. In Ruby, Sapphire, Emerald, Omega Ruby, and Alpha Sapphire, he is authorized by the Pokémon League to give new Pokémon trainers one of the three Hoenn starter Pokémon: Treecko, Torchic, and Mudkip.

While he does not give Michael his Eevee, he does give Michael the Master Ball.

They are voiced by Chinami Nishimura (Japanese), and in English by Lee Quick (Seasons 1-6), Jamie Davyous Owens (Season 7-8), Diane Stillwell (MoMP) Emily Williams in late Season 9 and onward, Maya Rosewood played her in a Season 9 episode, and Kayzie Rodgers (aka Jamie Peacock) voiced her in The Mastermind of Mirage Pokémon.
