Yu-Gi-Oh!/Characters/Supporting Characters


Seto Kaiba

Yugi's archrival who was undefeated at Duel Monsters until Yugi summoned Exodia to defeat him in a world-first. Since then he's been attempting to reclaim his title and challenge Yugi again. Barring that he frequently contends with people who have a grudge against Kaiba Corporation, usually due to the fact it was a weapons company under his father's ownership and thus he inherited a lot of blame when he took over.

He uses a dragon deck which focuses on summoning Blue-Eyes White Dragon, of which he has the only three intact copies in existence. He's also fond of Deck Destruction and removing cards from play.

In the Japanese version, he is initially voiced by Hikaru Midorikawa, and later Kenjiro Tsuda. In the English version, he is voiced by Eric Stuart.


"Reluctantly, I cut short the episode with Priest Seto and Kisara [due to editorial deadlines], which is something I still regret, because, as all of you guessed, it is the defining episode for the relationship between present-day Kaiba and his Blue-Eyes White Dragon." [1]

Mokuba Kaiba

Seto's little brother and his main fan. Can usually be seen either carrying his brother's briefcase or monitoring his brother's tournaments. While Kaiba is openly disdainful of Yugi and his friends, Mokuba gets along with them just fine, though he's still mostly on his brother's side when it comes to the rivalry he has with Yugi.

Voiced by: Junko Takeuchi (Japanese); Tara Sands (English)


  • Brainwashed: By Noah in Season 3 of the anime.
  • Creepy Child: When first introduced - the first thing he does in the series is challenge Yugi to a game, with the condition being that if Yugi lost, Mokuba would cut his fingers off. Second time you see him, he tries to poison Yugi - and succeeds in poisoning Jonouchi. It's only when his brother gets more evil and unhinged that this wears off and he actually starts being good.
  • Designated Victim / Dude in Distress: He gets kidnapped or is otherwise endangered at least once a season, usually more.
  • Disguised in Drag: In the Virtual Heroes arc, he switches outfits with his virtual counterpart Princess Adina to get himself kidnapped in her place and be taken to where Seto was.
  • Easily Forgiven
  • Heel Face Turn: Early in the series he hated Yugi just as much as Seto did, and in the manga tried to kill him. He eventually loosened up.
  • James Bondage
  • Morality Pet: To Kaiba
  • Smug Snake: During his time as villain, he was an even bigger example of this then Kaiba--he had all of his arrogance, but none of his skills.

Ryo Bakura

A friend of Yugi's from school, Bakura is a shy, quiet boy who lost his sister in a car crash some time before the series started. With his archaeologist father usually away from home, Bakura spends a lot of time by himself, or playing RPGs with select groups of friends. Unfortunately for him--and everyone else in the series--he's also the holder of the Millennium Ring, and is under the on-and-off control of the evil spirit living inside it (see below for more on that). Perhaps because of this, his favourite card is Change of Heart.

  • Accent Adaptation: He became British in the dub.
  • Adorkable
  • Anime Hair
  • Beware the Nice Ones: Bakura's a genuinely nice, if shy kid. The Ring...not so much.
  • Bishonen: Applies to all adaptations, but in the original toei anime, this is actually his nickname. In fact its rare that any female character in that season ever refers to him by his name instead of bishonen.
  • Clingy MacGuffin: Bakura's repeatedly tried to free himself from the Ring and the Spirit inside of it. No matter which one he attacks, it always comes back.
  • Dead Little Sister: His dead older sister, Amane.
  • Demonic Possession: By the Spirit of the Millennium Ring.
  • Demoted to Extra: In the anime Filler Arcs. In fact, he rarely appears in the anime when he's not under the control of the Ring.
  • Evil Counterpart: Bakura's Millennium Ring is the Evil Counterpart to Yugi's Millennium Puzzle.
  • Fake Brit
  • Foil: A shy kid with no friends who loves to play RPGs finds a Millennium Item. Am I talking about Yugi, or Bakura? In a sharp contrast of course, Yugi willingly partners with Yami, while Bakura is always the Ring's first victim.
  • Good Eyes, Evil Eyes: His round eyes nicely contrast with the Spirit of the Ring's narrow ones.
  • Heroic Sacrifice: Tries to make on in Duelist Kingdom, when, having been transformed into the card Change of Heart, he possesses on the Ring's monsters and orders Yami to attack him; this would have won Yami the duel at the cost of sending Bakura to the Card Graveyard.
  • Hyde Plays Jekyll: Good luck telling whether it's him or the Spirit of the Millennium Ring impersonating him at any given time.
  • Nice Guy: He really is, which makes his victimisation by the Ring all the sadder.

Mai Kujaku (Mai Valentine)

One of the best duelists around. She's a love interest for Jounouchi, the specifics varying from anime to manga and from original to dub. Though she isn't around in every episode, she's mostly a good guy and helps the heroes out frequently.

She uses a Harpie deck in season 1, and mixes it up with some Amazons in season 2.

Voiced by Haruhi Terada (Japanese), Megan Hollingshead (English Season 1-3) / Bella Hudson (English Season 4-5)


Shizuka Kawai (Serenity Wheeler)

Jounouchi's sister who lost her eyesight, Jounouchi entered duelist kingdom to win the money to pay for her operation to heal her. She accompanies the gang for most of Season 2 and all of Season 3.

The one time she duels, her deck doesn't have a theme other than the monsters are all female. Her trump card is St. Joan.

In the Japanese version, she is initially voices by Michiko Neya, and later Mika Sakenobe. In the English version she is voiced by Lisa Ortiz.


  • Amazon Brigade: Her deck is all female monsters, though they range from the exceptionally girly Forgiving Maiden to Fallen Angel Marie the Fallen One to Lady of War St. Joan.
  • Adaptation Dye Job: Her hair was pink in the Toei anime.
  • Badass Adorable
  • Beauty, Brains, and Brawn: The Beauty.
  • Beginner's Luck: Against Nesbitt. Sure she has lots of help from Honda and Ryuji, but the fact remains that she managed to take him down with cards she herself had picked out, despite not having a clue what most of them did.
  • Blonde, Brunette, Redhead: The Redhead.
  • Chekhov's Gun: At the start of the duel with Nesbitt we see her specifically selecting St. Joan (which ain't a bad pick). Guess which card takes out Nesbitt's Perfect Machine King?
  • Heroic BSOD: After Tristan is defeated by Nesbitt.
  • Ill Girl: During the first season, where she's going blind and Jounouchi wants to win the prize money for her operation.
  • The Ingenue
  • Lady of War: Not Serenity herself (though she certainly tries) but her trump card, St. Joan who with 2800/2000 is one of the better female cards in the game, and at the time the show was made, was one of the strongest Fairy monsters around. She's specifically modeled on Joan of Arc and has the looks to prove it.
    • And then, in the one time she duels with some bits of help, she takes down one of the Big 5.
  • Let's Get Dangerous: The duel between Yugi and Jounouchi during Battle City (rather, its consequences), in which she fearlessly jumps into the sea to rescue Joey after he sacrifices himself for Yugi.
  • Light Feminine and Dark Feminine: The light to Mai's dark. (One of two)
  • The Load: She starts out as this in her duel with Nesbitt, repeatedly requiring Tristan and Duke to bail her out (in her defence it was her first ever duel and she had to pick out her cards herself). She manages to take a level in badass and transition to Action Girl before the end of it.
  • Morality Pet: For Katsuya, her older brother.
  • Plucky Girl: She has her ups and downs, but still tries to do what she can.
  • Tomboy and Girly Girl: Girly Girl to Anzu's Tomboy.
  • Took a Level in Badass: You can spot the exact moment in the duel with Nesbitt where she decides to say "screw you" and starts channeling her brother for all she's worth.
  • Yamato Nadeshiko: Younger and a bit more insecure, though.

Ryuji Otogi (Duke Devlin)

The creator of Dungeon Dice Monsters and one of Pegasus' business partners. Has a real grudge against Yugi over Pegasus' loss causing their business deals to stagnate, but he gets over it and returns in the anime to join the protagonists for a while.

The first time he duels, he used a deck of cards randomly drawn from several booster packs. His true deck uses many dice effects, and many of the monsters emulate the ones from Dungeon Dice Monsters. His trump card is Orgoth the Relentless.


Leonhart von Schroider/Leon Wilson

Siegfried's little brother who dueled for fun using an alias until Siegfried found out about his hobby and recruited him to help him take down Kaiba Corp. Loves his brother but isn't entirely on-board with his schemes.

He uses a fairy-tale themed deck designed specifically for him by Pegasus. His trump cards include Hex Trude, Globerman, and Princess of Thorns. Siegfried later gives him Golden Castle of Stromberg.


Rebecca Hopkins (Rebecca Hawkins)

The granddaughter of the famous Egyptologist, Dr. Arthur Hopkins/Hawkins. She first appears seeking vengeance on the behalf of her grandfather by beating his old friend, Solomon Mutou, and taking his Blue Eyes White Dragon card and returning it to her grandfather. After her grandfather finds her and teaches her a valuable lesson about friendship, she quickly befriends Yugi and Solomon. During Season 4, she returns and becomes a member of Yugi's True Companions and accompanies him on his travels.

Her first deck concentrates on supporting Shadow Ghoul. Afterwards, she uses a dragon deck mixed with a Fire Princess Gain/Drain strategy. This deck's trump card is Diamond Head Dragon.


Season 4


Sugoroku Muto(Solomon Muto)

Yugi's grandfather and former game master, Sugroku currently runs the Kame Game Shop where Yugi and his mother live, and Yugi and his friends hang out.

Since he gave his original deck to Yugi, he uses an Ancient deck, with cards that emulate an explorer (the opponent) entering cursed and booby-trapped ruins, and gamble cards. His trump card is Ancient Dragon.


  • Badass Grandpa: When it comes to dueling anyway.
  • Cool Old Guy
  • Dirty Old Man: Early in the Manga.
  • Dude in Distress: He's kidnapped in the Death-T arc of the Manga and first animie, kidnapped in the first episode of the second anime, and finally trapped in a video tape(Manga)/Duel Monsters Card(Anime). Let's just say the old man's been though a lot.
    • He also get's held hostage by Vivian Wong (granted she threw his back out of place, but same principal) and even get's kidnapped during his guest appearance on Yu-Gi-Oh! GX.
  • The Mentor: To Joey, who he taught to duel.
  • Miniature Senior Citizens: Though given how short Yugi is, it may well be genetic.
  • Old Master: Was a big gamer like his grandson in his youth and even particaptes in the Kaiba Grand Prix.
  • The Other Darrin: In 2008, Sugroku's english dub voice actor, Maddie Blaustein, passed away, so when Bonds Beyond Time aired, Wayne Grayson took over.
  • Paper-Thin Disguise: As Mask The Rock. He doesn't even change out of his normal outfit.
  1. The rest of the liner notes are too long to post, but basically he describes how Kisara's death at the hands of Aknadin would have led to a subplot where Seto betrays the pharaoh and goes off on his own with the intent to avenge her demise. But apparently the series was starting to get less popular and the editors wanted Kazuki Takahashi to rush to finish the story, so his grand plans for the above were cut short.
  2. Marik only had one monster in Attack position with 500 ATK and 1050 Life Points, Mai had Cyber Harpie with 1800 ATK
