The following is a list of characters for the Yu-Gi-Oh! anime series, Yu-Gi-Oh! Zexal and its sequel, Yu-Gi-Oh! Zexal II. Where appropriate, names from English-language anime are on the left, while the original Japanese names (used in Volume 1 of the English-language manga) are on the right. Character descriptions pertain to the Japanese version of the anime.
The main protagonist of the series, a 13-year-old cheerful and energetic boy who is an underachiever in both school and duels, but always takes on any challenge and never gives up, an ethic he dubs "Feeling the Flow" or "Kattobingu da ore" (かっとビング,Kattobingu?, adapted from the Japanese word "katto"). Yuma is the current duel champion of Heartland City. Yuma's dream is to become the strongest duelist in the universe, but his dueling skills aren't that skillful. He wears a special key named the emperor key given to him by his traveling parents, which manages to unlock a door to another dimension, where he encounters Astral. He uses a Deck given to him by his father, largely consisting of monsters that have notable play on words. Many of his monster cards are Light and Earth attribute, especially his Xyz monsters. His ace card is "Number 39: Utopia", which is later able to be evolved into "Chaos Number 39: Utopia Ray". Later he is given "Rank-up Magic Limited Barian's Force" by Ray Shadows which is able to evolve Utopia into "Chaos Number 39: Utopia Ray V". He later obtains "Rank-Up Magic Numeron Force", which is able to evolve Utopia into "Chaos Number 39: Utopia Ray Victory". A new magic card called "Rank-Down Magic Numeron" Fall grants Yuma the ability to summon a new evolution of Utopia, "Number 39: Utopia Roots". Another Rank-Up card, "Rank-Up-Magic Astral Force" allows Utopia to evolve into "Number 39: Utopia Beyond". In his duel with Astral, Yuma gains a unique Number of his own creation, "Future Number 0: Utopic Future".
By combining his soul with Astral's, Yuma can obtain the power of Zexal. There are currently four known Zexal forms. The first Zexal form allows Yuma to perform a "Shining Draw" and draw "Zexal Weapon" monsters from his deck, which he can use to power up Utopia. Following a battle against Vector, he gains the power to become Zexal II, which allows him to transform a card in his hand. In one instance where Astral was attacked by Vector's darkness (only revealed to be controlled by the power of Chaos) he then fused with Yuma into a Dark Zexal form, and can draw "Dark Zexal Weapons". When Yuma is in a head-to-head combat with Mr. Heartland he undergoes another transformation called Zexal III which allows them to maintain the Shining Draw and now they are able to use an ability called "Zexal Field".
The "Original Number", Astral is a mysterious spirit from another plane of existence who has to carry out an important mission, but unfortunately, Yuma is the only one who hears and sees him. A calculating person, Astral makes a list of his observations of Yuma and other human behaviors while offering his dueling wisdom to the boy in order to obtain the 99 "Numbers" Cards which are actually fragments of his memories which got scattered when he entered Yuma's dimension. It is thanks to his tuition that Yuma gradually becomes more skilled and experienced as a duelist while maintaining his positive outlook on life. Yuma and Astral's partnership is shown to be one of equals, though: from Yuma, Astral learns to be more positive and in touch with his emotions. He normally resides in a special world within Yuma's Emperor Key, featuring a strange ship whose parts become unlocked as Astral collects more "Numbers" cards. However, Astral is horrified to learn that his purpose is to destroy the world. Eventually, this is revealed to be a deception by Number 96 which turns out to be a corrupted memory known as a Forbidden Number. His true purpose as mentioned by Eliphas and later confirmed by Astral himself, is to destroy Barian World.
Yuma's rival and a good friend and one of the main characters who was originally a championship duelist before he was disqualified for peeking at his opponents cards, eventually becoming a delinquent and taking the nickname "Shark". Shark is now close friends with Yuma and fights the Barian threat alongside him and Kite. During his duel against Yuma, he is briefly possessed by the Number card, "Number 17: Leviathan Dragon", but Astral takes it from him after Yuma defeats him. Like his namesake, he uses a deck filled with fish-type monsters, many being based on water and darkness, his key card being "Black Ray Lancer". This Xyz monster is normally unable to destroy Numbers, but Shark seems to have put some workarounds into his deck, such as the Spell card "Armor Xyz", which equips an Xyz monster with a second one, giving the first its attack points and Number status if the equipped monster is a Number. Shark eventually obtains "Number 32: Shark Drake" to use as his new ace card. He later gains the ability to evolve "Shark Drake", much like how Yuma can evolve "Utopia", but, rather than through the feeling of love, Shark acquired it through feelings of hate. After this, Shark can summon "Chaos Number 32: Shark Drake Veiss" at will. He then later obtains a new ace "Number 73: Abyss Splash". He is later revealed to be Nash, the leader of the Seven Barian Emperors.
It is believed Vector had killed Nash, alongside Marin, however they were saved by Abyss who transferred their souls into the bodies of Reginald and Rio causing them to live on as children with amnesia. When they regain their memories they decide to leave Yuma's group and rejoin the Barians. Despite this, he does not wish his former allies ill: he is simply trying to prevent tragedy from occurring to his people. His new ace is "Number 101: Silent Honor ARK". Using "Rank-Up-Magic The Seventh One", he can upgrade his monster into "Chaos Number 101: Silent Honor DARK". He is killed when Don Thousand's curse is dispelled, but he is revived and chooses to live on as Shark.
Yuma's classmate and childhood friend. She will usually use her D-Gazer to watch augmented reality duels. Tori also controls a fairy-type deck. She is shown to never leave his side, no matter what the circumstances, and seems to harbor a crush on Yuma. In the final episode of Zexal ll, she confessed to him that she loves him, then adding in his smile as well, which caused Yuma to greatly blush as she grasped his hand (in the dub it is still made blatant by her stating that she is Gagaga for him). She is also intelligent, and good with computers. She has developed a rivalry with Cathy for Yuma's affections.
Kite is the son of Dr. Faker, a "Numbers" Hunter, and one of the main characters who was collecting "Numbers" for his father in order to help his formerly sick brother, Hart. Kite now fights the oncoming Barian threat alongside Yuma and Shark. Assisted by a robot named Orbital-7, he has the ability to stop time for everyone except those that possess "Numbers". When Kite defeats a "Numbers" Holder, he uses an ability called Photon Hand to remove the "Numbers" card from the person, taking their soul alongside with it, thereby rapidly aging the body of the person affected. Formerly, Kite possessed 15 "Numbers", but they are now in the possession of Yuma. He wields a "Photon" deck, focused on extraterrestrial monsters and magic, and many of his monsters are associated with light and wind as a consequence. His key card is "Galaxy-Eyes Photon Dragon", an anti-Xyz support monster. Kite later upgrades his monster with Hart's power, granting him the Xyz Monster "Neo Galaxy-Eyes Photon Dragon". He later obtains the Number monster "Number 62: Galaxy-Eyes Prime Photon Dragon".
Rio Kastle (神代 璃緒,Kamishiro Rio?) / Marin (メラグ,Meragu?)
Rio is the younger twin sister of Shark. As a part of Vetrix's plan to use Reginald as their assassin against Dr. Faker, he sent his son Quattro to duel her. It was there that Quattro played a card given to him by Vetrix which unknowingly caused the field to go on fire. Quattro was able to take Rio to safety, but she was severely injured.Quattro later lied and told Reginald that he intentionally hurt his sister to keep with the plan, even though he hated the idea that Vetrix was using him to commit atrocious actions. She eventually regains consciousness after Shark saves her from one of Barian's mind slaves and enrolls into Yuma's school. Rio is initially shown to be a polite girl with charming looks and great athleticism that earn her attention from her classmates (especially Bronk, who develops a crush on her). However, as her brother Shark knows, she is actually quite irritable and stern. Despite all of this, she is afraid of cats. She is later revealed to be Marin, of the Seven Barian Emperors.
It is believed Vector had killed Marin, alongside Nash, however they were saved by Abyss who transferred their souls into the bodies of Reginald and Rio causing them to live on as children with amnesia. When they regain their memories they decide to leave Yuma's group and rejoin the Barians. Her new ace is "Number 103: Ragnazero". Using "Rank-Up-Magic The Seventh One", she can upgrade her monster into "Chaos Number 103: Ragnafinity". Although she is absorbed into Don Thousand in the series' climax, Astral revives her and she chooses to live out the rest of her life as Rio.

He develops a crush on Shark's sister, Rio. He plays a Gearspring deck; his ace card is "Tin Archduke".
A wily and mischievous kid who often notes that everything in the whole world has a flipside. His English name is a reference to Flip-Effect monsters in the Yu-Gi-Oh trading card game. Having been bullied and considered unintelligent when he was younger, Flip had learned to play dirty in order to win duels. However, after Yuma beats him in a duel, he learns to be more friendly. In the manga, one of his quotes "Everyone has an agenda" is used repetitively. According to Yuma, he considers an agenda a fancy word for a day planner. His deck mainly consists of monsters that use Flip Effects, and he has a habit of ending his sentences with "ura", meaning "reversed". Flip has a crafty personality similar to the character Weevil Underwood from the original Yu-Gi-Oh! series. Flip has a very big tendency to scheme and to prank others. In the WDC, he uses a zombie type deck that doesn't consist of xyz monsters.
Known as Cat for short, Cathy is a shy girl who has a crush on Yuma but doesn't stand out too well in class. As a result she sometimes sneaked into Yuma's room to do various things while he was asleep. She is slightly more confident as a duelist, using a Cat themed deck.

The father of Kite and Hart Tenjo and the main antagonist for the first half of the series, he is a seemingly evil man who desires the destruction of the Astral World via the forceful collection of all 100 "Number" cards. His evil persona is later revealed as nothing more than a farce, due in part to the revelation of a deal with a being called "Barian" regarding the well-being of Hart. As such, he took extreme interest in Hart's power, and is therefore overprotective of him. Faker was responsible for the mutation of Vetrix and the disappearance of Kazuma Tsukumo. He is somehow similar to Dr. Eggman from the Sonic the Hedgehog video game series and TV shows, but whereas Dr. Eggman collects chaos emeralds to rule the world, Faker collects number cards to heal Hart. In the manga, Dr. Faker died of an incurable illness and Mr. Heartland had been keeping this a secret to manipulate things in his favor.
Mr. Heartland is the person in charge of relaying Dr. Faker's orders to Kite Tenjo and is the current Mayor of Heartland and a minor antagonist.

Vetrix duels using a "Heraldry" deck, a deck focusing on control and manipulation. Vetrix was the one who ordered Quattro's attack on Rio Kastle. Vetrix also has the ability to steal people's memories and corrupt people's hearts, as shown when he took away Dextra's memories of Kite and used his crest to amplify Shark's feelings of hate. Following his loss to Yuma, Vetrix has reformed and left Heartland City to be with his sons. He wasn't seen in ZEXAL II, though mentioned but his sons reappeared in the series to aid Yuma and his friends fight the Barians mentioned until the final season where he is seen speeding toward Yuma and Nash's duel with Kazuma and revealed to him that he had found a way to stabilze the worlds by creating a sphere. He later worked with Dr. Faker, Kite Tenjo, Hart, and Orbital 7 help reopen the doors to the parallel worlds.

He was later defeated by Shark in the WDC finals when he used Shark Drake Vice to destroy Gimmick Puppet of Leo and win the duel.

He then entrusts Shark to save his father before disappearing. He later appeared in season 2 of ZEXAL II where he aids Shark to fight Chironex in order to save his sister from being poisoned. After finding out Shark is the Barian Nash, he duels him again in order to bring back Shark and ranks up his "Gimmick Puppet" number monsters to take on Nash's ace, "Number 101: Silent Honor Ark" which later took on its chaos form, "Number C101: Silent Honor DARK, but was later defeated and got sacrificed to the Barian world.

His appearance is similar to Black Doom from the Shadow the Hedgehog video game.
An Emperor from Barian World, he manipulated Dr. Faker and Vetrix to achieve the Barians' agenda of destroying Astral World. After his first defeat, he orchestrated a new scheme by taking on a human form on Earth and calling himself Ray Shadows, becoming friends with Yuma Tsukumo as a gambit to orchestrate the latter's fall. When that failed, Vector released the God of Barian World, Don Thousand and became his current host.

With the defeat of both Vetrix and Dr. Faker, Dumon determined that they would have to do it themselves. To that end, he sent his comrades to Earth to search for the "Numbers".

The most prominent Xyz Monsters in the anime series are the Numbers cards, some of which have Chaos Numbers counterparts.
This is simply new terminology for an old mechanic: the mechanic in question requires a player to sacrifice monsters in order to activate certain effects. When a player sacrifices a monster, he or she is now said to tribute them: an example is tribute summon, where Level 1-4 monsters are sacrificed or paid as tribute to summon stronger monsters such as Galaxy-Eyes Photon Dragon and Jawsman. Number monsters could also be tributed.
