Mokuba Kaiba (海馬 モクバ; kaiba mokuba)
Voiced by: Katsue Miwa (Japanese Toei anime), Junko Takeuchi
(Duel Monsters), Tara Sands (English), Carrie Keranen
(English, season five onwards)
Seto's little brother and his main fan. In contrast to his brother's obsession with Duel Monsters, Mokuba has an obsession for Capsule Monster Chess. 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.
- Adaptational Heroism/Took a Level in Kindness: Mokuba is much nicer in the second anime than he is in the manga.
- Big Brother Worship: He adores his brother, even when he's being a jerk to the other characters.
- 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/Distressed Dude: 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: Less so in the second anime, moreso in the manga, where he comes off as being almost bad as Seto was, until he decides to nearly kill him, which does earn him some sympathy
- In turn, he really seems to be this towards Noah.
- 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.
- Jerkass Fašade: In the manga after his Heel-Face Turn, he still displayed bits of a Jerkass attitude not unlike his brother, but as opposed to Seto it's clearly an act. The driving point of this is at the end of Duelist Kingdom where he mocks Yugi and the others, then almost immediately softens up.
- Morality Pet: To Kaiba.
- Orphanage Of Relentless Bullying
- Screw the Rules, I Have Money!: During the early manga and the Toei anime.
- 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.
- The Dragon: During Death-T.
- Trauma Swing: Spent his first day in the orphanage on a playground swing, where only Seto regarded him.
- Young And In Charge: As Battle City Commissioner.
Ryo Bakura (獏良 了; bakura ryou)
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 — particularly Monster World. 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). Along with his love for the Tabletop R.P.G. genre of gaming, he has a penchant for the occult, even making a Duel Monsters deck out of it, which freaks Jonouchi out to no end.
- Accent Adaptation: He became British in the dub.
- Adorkable: Even moreso than Yugi
- Anime Hair: A more traditional one.
- Beware the Nice Ones: Bakura's a genuinely nice, if shy kid. The Ring...not so much.
- Badass Adorable: As White Mage Bakura. Season 0, in the final episode, he stands up to Yami Bakura. Of course, through Power of Friendship he stood his ground and never backed down.
- Beauty Equals Goodness
- Bishōnen: 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.
- Born Unlucky: His precious sister died in a car crash. He had to constantly change schools, living with the guilt and negative stigma of having his friends fall into a coma whenever they played a game with him because of the evil personality within the Millennium Ring. After Yugi and his other Domino High friends free him of the Ring's influence the first time, he is tricked to give his body up to Dark Bakura yet again so they could escape the underground maze of Duelist Kingdom, becoming an unknowing pawn for the spirit thereafter. At the beginning of the Millennium World arc, Bobasa refuses to let him into the Pharaoh's mind, despite his desire to help his friend, because of the darkness within his heart, which we all know is the evil spirit of the ring. He puts on a smile, and runs away, in tears. The only lucky thing that ever happened to him is possibly having friends that never gave up on him.
- Brown Eyes
- Chick Magnet: Season 0 takes this Up to Eleven.
- Unwanted Harem: On his first day of being the new kid in Yugi's school, all the girls in his class already fall head over heels for him. However, as sweet and kind he is, he actually doesn't like the attention all that much. Hell, as soon as he met Miho, he turned and walked away because of how she started fangirling around him. From his reactions, this isn't the first time that he's attracted females. And Jonouchi is jealous of him because of this.
- The Chosen One: In a very unfortunate and literal way. He is the "chosen host" for the Pharaoh and the Spirit of the Millenium Ring's final battle. This translates to him having the "honor" of being frequently possessed by the Spirit and being the one to build the Memory World diorama on which the final Shadow Game takes place.
- 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.
- Declarationof Protection: He would give up his life if it meant saving them from Yami Bakura. Even when he barely knew them.
- 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.
- Only in the anime, of course. In the manga, Bakura is treated as part of the main group after his initial introduction and appears with them for most of the stories. Except in the Memory World saga, where he wasn't allowed to enter the Pharaoh's mind due to the darkness in his heart... and we all know who that's referring to.
- Disappeared Dad: His father is always away, leaving poor Ryou to live alone and deal with Yami Bakura.
- Distressed Dude/Designated Victim: He's always the Millennium Ring's first victim.
- Evil Counterpart: Bakura's Millennium Ring is the Evil Counterpart to Yugi's Millennium Puzzle.
- Fake Brit: In the dub.
- 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.
- Friendless Background: Averted! And how! He did have a lot of friends, but thanks to the spirit of the Millennium Ring, all of them ended up comas because Yami Bakura would play shadow games with them. Causing poor Ryou to transfer schools like no other.
- Game Master: Although never shown on-screen in the position, he love building game boards and figures due to his love for Tabletops (even making a giant diorama of Ancient Egypt that serves as the battleground for the final arc), and would play with his friends more often if it wasn't for his Killer Game Master Super-Powered Evil Side.
- Killer Game Master: Arguably. Even without taking the Spirit's cheating into account, Ryou's shown scenarios of Monster World and Memory World are heavily biased against the players. While the second may be explained by it having been requested by the Spirit, the first was entirely created by him.
- Good Eyes, Evil Eyes: His round eyes nicely contrast with the Spirit of the Ring's narrow ones.
- Heroic Sacrifice: Tries to make one 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.
- The manga's equivalent of that scene plays this trope straight during the Monster World RPG arc, until Bakura is revive by a dice roll and his character's special ability.
- Hyde Plays Jekyll: Good luck telling whether it's him or the Spirit of the Millennium Ring impersonating him at any given time.
- Impaled Palm: Happens during the Monster World arc when Dark Bakura finds out that Ryo had taken control of his left hand, and then proceeds to impale it on one of the game's towers. Ouch.
- Incorruptible Pure Pureness: Even with the death of his dear little sister(implied to have lost his mother too), losing all his friends(not counting his current friends) who are now in comas, his father barely in the picture, being alone and dealing with Yami Bakura, its amazing how Ryou never once made a Face-Heel Turn.
- Masculine Girl, Feminine Boy: A Platonic version of this, Anzu shows a lot more aggression, and has her Action Girl moments, while Ryou is quiet, shy, and likes to keep to himself. He doesn't seem to like fighting, and would rather be a Nice Guy about most things. Unless when it comes to dealing with Yami Bakura.
- Mr. Exposition: The dub seemed to give him this role in the Duelist Kingdom arc. Most of his lines are generally spent describing what the Duel Monsters do, the basic rules, or what Yugi and/or Jonouchi's strategies are supposed to be.
- Missing Mom: It's implied that his mom died when he was younger. Many fans have theories that his mother was killed alongside his little sister.
- New Transfer Student: His manner of introduction...and turns out to be his shtick, thanks to his Dark and Troubled Past.
- Nice Guy: He really is, which makes his victimisation by the Ring all the sadder.
- Non-Action Guy: Ryou himself doesn't actually duel that much, he prefers Monster World. And he doesn't get into fist-fights like Honda and Jonouchi do.
- No Sense of Personal Space: In duelist Kingdom, when Yugi hit his Heroic BSOD moment, through Anzu's duel with Mai, he held onto Yugi's shoulders. Not once letting go until the duel is over, sure it was his way of comforting Yugi, but Jonouchi did the same thing, and let go moments after the duel began.
- Ship Tease: With Yugi in season 0, and a bit within the first arc of the second anime. And with Anzu, though with her it was just a matter of the two of them being nearly side-by-side in many of the scenes of Duelist Kingdom arc. It wouldn't be much of a surprise seeing as how Anzu is the only girl that hasn't fangirl over him.
- In the abridged, he was often hitting on her and Yugi.
- Shrinking Violet: He rivals Yugi's own Shyness.
- Shy Blue-Haired Guy: In the toei anime, he had blueish hair, but he was still just as shy as ever.
- Single Woman Seeks Good Man: Besides being good-looking, it may be why Miho got a huge crush on him. Much to his dismay. Most of his fangirls would also tell you this as well.
- Supreme Chef: When the gang camped out with Mai during Duelist Kingdom, Bakura was said to be this.
- White Hair, Black Heart: His dark side is this, but otherwise averted.
Mai Kujaku (孔雀 舞; kujaku mai) (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.
- Action Girl: She is a genuinely good duelist, even though she ends up getting put up and losing against the most important and/or powerful duelists in almost any given arc, but never without a fight.
- Amazon Brigade: Her deck, which includes her Harpies and some actual Amazons.
- Badass Normal
- Be My Valentine: In the dub. The "Mai" adds to it as a pun.
- Beauty, Brains and Brawn: The Brawn.
- Biker Babe: Season 4
- Blonde, Brunette, Redhead: The Blonde.
- Break the Cutie: During the Battle City arc.
- Broken Harpie: Again, during Battle City.
- Christmas Cake: Actually, by her own choice. She did have a Hopeless Suitor and blew him off, defeating him in a duel when he wouldn't give up.
- Compressed Hair: She can somehow keep all of her hair into a normal-sized motorcycle helmet.
- Cool Big Sis: To Serenity
- Dark Action Girl: Season 4.
- Dark Chick: In Doma's Five-Bad Band.
- Defrosting Ice Queen: Throughout Duelist Kingdom.
- Demoted to Extra: After Doma she's relegated to just making a couple of silent cameos for the remainder of the anime.
- Designated Victim: Silly Mai, this is a Shōnen manga, girls at your time can't win fights yet.
- Deus Angst Machina/Trauma Conga Line: From Dark Marik's Penalty Game to Doma.
- Distracted by the Sexy: An implied reason for her choice of outfits is to try to distract her opponents.
- Evil Costume Switch: Developed a taste for black leather after joining the Doma cult.
- Fanservice: She and her monsters are this
- Get A Hold Of Yourself Man: Does this to Joey during Battle City after his Brainwashed and Crazy period.
- Idiot Ball: Gets a lot of this.
- Has a run-in with it at the end of her duel with Marik. Despite having the means to win the duelnote by just declaring an attack, she chooses to try and beat Yami Marik with the Winged Dragon of Ra, despite the fact she has no idea how it works and a first-hand demonstration in the previous duel that using the card is highly dangerous.
- It happens again in Season 4: when she duels Raphael, Mai attempts to use Jonouchi's Helmos card despite not being one of the three chosen duelists. It doesn't go well for her.
- Light Feminine and Dark Feminine: The dark to Anzu and Shizuka's light.
- Lonely Rich Kid: In her backstory, at least in the anime. We see her as a little girl, all alone in a Big Fancy House...
- Meaningful Name: Mai Kujaku means "dancing peacock."
- Mind Rape: By Marik during Battle City. In the anime, this lead to a Heroic BSOD and a Face-Heel Turn in the Doma filler arc.
- More than Mind Control: How Dartz got her to serve him.
- My God, What Have I Done?: After she beats Jounouchi in the Doma arc, causing him to lose his soul.
- The Other Darrin: Megan Hollingshead was replaced with Bella Hudson after Season 3.
- Overshadowed by Awesome: She's a very good duelist and strategist, but has the misfortune to be on the same team as Yugi and Kaiba (who have connections to Ancient Egypt and some of the most powerful cards around) and ends up going up against Dark Marik in the Battle City semifinals.
- Punny Name: In English.
- Red Oni, Blue Oni: The blue to Jounouchi's red. (One of three)
- Ship Tease: With Joey.
- Spared by the Adaptation: In The Sacred Cards, a video game adaptation of Season 2-3, she duels Kaiba in the Battle City finals instead of Marik.
- Thigh-High Boots: Wore these while she was Brainwashed by Dartz during the Doma arc.
- Tsundere: Shifts from a Type A to a Type B over the course of Duelist Kingdom.
- Unresolved Sexual Tension: With Jounouchi.
Shizuka Kawai (川井 静香; kawai shizuka) (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 and religous (which goes with her former Ill Girl
status). Her trump card is St. Joan.
- Action Girl: Manages to play the part by the end of her duel with Nesbitt.
- 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 to Tea's Brains and Mai's Brawn. One could argue that in her duel alongside Duke and Tristan she also plays this role, with Tristan as the muscle, and Duke the brains.
- Beginner's Luck: Against Nesbitt. Sure she has lots of help from Tristan/Honda and Duke/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.
- Big Brother Worship: Like Mokuba, she loves her big brother, despite being separated from him for years. Her love for Joey extended to her jumping in the river after having her eye surgery. Talk about devotion.
- Big Damn Heroes: Before she removed her bandages, the show plays her off as an Ill Girl who needs escorting and to be with someone. What does she do right as she takes them off? Dives into an ocean from a pier, and saves her drowning brother.
- 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?
- Dude Magnet: For part of the Battle City Arc, Duke and Tristan fight for her affections. In the end, they both try giving her their numbers.
- Grew a Spine: She wasn't a coward at first, but she spends most of her duel with Nesbitt scared and confused. Towards the end, she finally develops a backbone and comes back strong, taking Nesbitt down after Duke fails.
- 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
- Best shown after Yugi's defeated Marik, and Mai should be back. She appears to be the same, and Joey's really worried, even saying he'd do anything to get her back... only for Mai to start laughing, saying he fell for it hard, and thanking Serenity for helping her. An utterly-confused Joey looks at her, and she simply sticks her tongue out as she giggles.
- 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.
- Doesn't apply to the manga, of course, where it was Kaiba who dropped the key into the sea so Jonouchi could set himself free, showing a small ounce of respect.
- 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.
- Meaningful Name: Kawaii means cute in Japanese. Shizuka means quiet, or silence. Her English name Serenity reflects this.
- Punny Name: Kawaii, meaning "cute," is written as 可愛い, while the way it's written in her name (川井) means "river well", but it's clearly meant to reference "cute."
- Morality Pet: For Joey/Katsuya, her older brother.
- Oblivious to Love: She didn't realize that Tristan/Honda liked her and she called him her friend.
- 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.
Ryuji Otogi (御伽 龍児; otogi ryuuji) (Duke Devlin)
Voiced by: Ryo Naitou (JP), Marc Thompson (EN)
The son of the owner to Kame Game's rival game shop, the Black Crown, and an expert at Bar Bet games. His dad lost a Shadow Game to Yugi's grandpa, which disfigured his face horribly. He was raised to take revenge upon Yugi's grandpa by beating Yugi in a game and taking his Millennium Puzzle, declaring himself the King of Games. Unfortunately for his dad, he eventually becomes good friends with Yugi instead. He's the creator of Dungeon Dice Monsters (DDD in the manga) and (in the anime only) one of Pegasus' business partners and fans, and added Duel Monster creatures to his game as a tribute.
In the anime, instead of being raised as a tool of vengeance by his father, he has a real grudge against Yugi over Pegasus' loss causing their business deals to stagnate, but he gets over it after the game hits it big. His personality in the anime is also radically different from his personality in the original manga.
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. He never duels in the manga.
- Abusive Parents: In the manga. His dad raised him as a tool of vengeance and was seen whipping him after he found out he lost to Yugi in a game of Four Aces.
- Alliterative Name: In the dub.
- Ascended Extra: The filler arcs were kind to him in the anime, giving him more screentime and allowing him to duel a couple times, while in the manga he never got any such action after his introductory arc.
- Badass: Though he doesn't get to duel as often as the other characters, he is still an excellent game master and a perfectly competent duelist. He also uses dice as a weapon when attacking people.
- Badass Boast: Quite often when he challenges Yugi to Dungeon Dice Monsters, though it gets exaggerated in the dub.
- Defeat Means Friendship/Easily Forgiven: Even after all the crap he puts Jonouchi and Yugi through in the anime, Yugi and the gang forgives him, and it's helped when Dungeon Dice Monsters gets commissioned.
- Depending on the Writer: In the manga, he's a serious character with emotional problems stemming from daddy issues, comparable to Kaiba. In the anime, he's a narcissistic guy who somewhat revels in the attention he gets from girls and after he joins the gang, he forms a comedic duo with Honda for Shizuka's affections.
- Foil: Like Yugi, he's the youngest relative of a game shop owner and is an expert at games. Unlike Yugi, he is tall, handsome, but has a horrible relationship with his father and starts off with no friends other than his legion of fangirls, most of which also belonged to Bakura at one point.
- The Gambler: Uses dice as weapons, runs a gamble deck focused on powering up his Orgoth the Relentless, and created the luck-based game of Dungeon Dice Monsters.
- He challenges Jonouchi and Yugi to Bar Bet games in the manga, games with fixed probability that are meant to trick his opponent in a gamble.
- Graceful Loser: Subverted when he gets distraught after being beaten by Yugi in a game of Four Aces. Played straight after he loses to Yugi in Dungeon Dice, and realizes he doesn't hate nor mind losing to Yugi at all. He was willing to hand the Millennium Puzzle over until his father intervenes.
- Green Eyes
- Improbable Weapon User: Dice, which he regularly tosses at people who try to catch them.
- Jerkass: In the anime, he starts off almost as bad as Kaiba was pre-Mind Crush. He gets over it when Yugi wins.
- Love Triangle: With Honda over Shizuka. Doesn't apply in the manga, however, since he's a much more serious character and less narcissistic about being popular with the ladies.
- Oh Crap: Repeatedly in his DDM game with Yugi.
- "The Reason You Suck" Speech: Very judgmental variations of this trope were used at Yugi throughout their Dungeon Dice Monsters match.
- Took a Level in Kindness: After losing his Dungeon Dice Monsters match against Yugi, he became a LOT easier to get along with.
- Ship Tease: With Honda (especially in the abridged series) and Shizuka.
- Sins of Our Fathers: His father lost a Shadow Game to Yugi's grandpa, and he wanted Otogi to beat Yugi in a game and take his Puzzle.
- Smug Snake: In the dub anime during his Dungeon Dice Monsters game with Yugi, he's completely confident that Yugi is just a glorified cheater who doesn't stand a chance against him since he made the game and Yugi is an amateur who doesn't have any idea of proper strategy. Yugi's repeated use of Didn't See That Coming against him shakes him, but he brushes such instances off as luck. He mellows out once he loses.
- The Stoic: In the original manga.
- Those Two Guys: With Honda/Tristan. Again, only in the anime.
Rebecca Hopkins (レベッカ・ホプキンス; rebekka hopukinsu) (Rebecca Hawkins)
Voiced by: Kaori Tagami (JP), Kerry Williams (EN)
An anime-only character. 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.
- Child Genius: She's a twelve year old college student.
- Dub-Induced Plot Hole: 4Kids lowered her age from twelve to eight, which became a bit of a problem when she returned in season 4. Amusingly, they would later make the same mistake with her Expy, Rei/Blair.
- Little Miss Badass: Is quite the Action Girl.
- Odd Friendship: With Anzu, who is also her (sort of) rival in love, but they still act like an older/younger sister pair.
- Playful Hacker
- Precocious Crush: She has one on Yugi, which is a constant source of irritation for Anzu.
- Self-Proclaimed Love Interest: She claims that Yugi is her boyfriend.
- She Is All Grown Up: Well, not really, but she likes to act it (example: she ditched "Teddy".)
- Ship Tease: As noted above, she has a crush on Yugi. She is also the only character in the entire series to kiss anyone, giving Yugi a goodbye kiss before leaving the second time.
- Plus, she's devastated when she hears of Yugi's soul being captured and determined to avenge him when Valon shows up, a huge step up from Tea just being shocked in a normal way.
- The Smart Girl
- Took a Level in Kindness: Now is comfortable hanging with Yugi's friends and has mellowed out quite a bit.
- Youthful Freckles
- Zettai Ryouiki
Sugoroku Muto (武藤 双六; mutou sugoroku) (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.
- Adventurer Archaeologist: Used to be one. His deck plays straight to that.
- Awesome, but Impractical: His Ancient Dragon requires a half-dozen cards and several turns to prepare to summon, but once out it's a 2800 point beatstick that destroys all enemy monsters when it beats one in battle, and when destroyed in any way returns at the end of the turn as long as Ancient City is on the field. Hawkins even notes the reason Grandpa is so proud of it is that its cards are so rare and it's so hard to summon, no one else they know has ever done it.
- Similarly his Exodia deck, to some extent. The dialogue about the Exodia cards implies there are little to no card shuffling tactics to gather the cards more efficiently. Also, Sugoroku only has one of each card in his deck. However, drawing all five cards is an instant win.
- Badass Grandpa: When it comes to dueling anyway.
- Cool Old Guy
- Dirty Old Man: Early in the manga.
- Distressed Dude: He's kidnapped in the Death-T arc of the Manga and first anime, 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 through a lot.
- He also get's held hostage by Vivian Wong (granted, she threw his back out of place, but same principle) and even gets 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 participates in the Kaiba Grand Prix.
- The Gambler: Rivaled Yami Yugi during his younger days.
- 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, he just puts on a mask.
- Reincarnation: Of Siamun Muran, the Pharaoh's vizier.
- Retired Badass
