Yako Tenma (天馬夜行;Tenma Yakōu)
The main antagonist of Yu-Gi-Oh! R. He is the protégé and adopted son of Pegasus, and the biological twin brother of Gekko Tenma, who wants revenge for Pegasus' death and disappearance, although unbeknownst to him, it was actually Dark Bakura who killed him.
Yako uses a Wicked God Deck that focuses on Level modification tactics to bring out multiple monsters, which he can Tribute for the Summoning of the Wicked Gods, particularly The Wicked Avatar.
- All Your Base Are Belong to Us: He takes over KaibaCorp to use its vast technology in his plot.
- Avenging the Villain: Unfortunately, Yako's trying to get revenge on the wrong person; other than defeating him at the end of Duelist Kingdom, Yugi didn't have a thing to do with Pegasus's death. The real culprit never even makes an appearance.
- Big Bad: of Yu-Gi-Oh! R
- Brainwashed and Crazy: Yako is possessed by the Wicked Avatar. Gekko could also qualify during the period he is controlled by Yako.
- Cain and Abel: Inverted - Yako is the younger but evil brother, while Gekko is the older but good brother.
- Canon Foreigner: He's only appeared in a spin-off so far.
- Cherry Tapping: The Wicked Avatar is always exactly ONE attack point stronger then the strongest monster on the field, but as Yako points out, that one attack point makes all the difference.
- Cloning Blues: Played with, as while Yako and Gekko are natural identical twins, flashbacks reveal that Yako always felt like an inferior copy of his twin brother.
- Comically Small Bribe: His initially offered bounty for defeating Jonouchi, a Duelist Kingdom finalist and Battle City semi-finalist, is a paltry $10. Jonouchi isn't happy when Tilla informs him of this.Jonouchi: *thinking to himself* I hate you, Yako...
- Evil Counterparts: The Wicked Gods for the God Cards, and possibly Yako himself for Gekko, depending on how you look at it.
- Expy: Yako is Pegasus's Expy. Goes crazy after losing a loved one? Check. Wants to bring said loved one back regardless of what it takes? Check. Takes someone close to Yugi as hostage? Check. Even lampshaded by Gekko when he mentions Yako is just like Pegasus.
- I Have Your Wife: Yako kidnapping Anzu drives the entire plot.
- Mad Eye: His right eye bulges very nastily when he's at his most volatile.
- Revenge by Proxy: Yako targets Yugi by turning Anzu into a Human Sacrifice so he can resurrect Pegasus.
- Sempai/Kohai: Yako is Pegasus' kohai. One of them.
- Shapeshifter Guilt Trip: During the final showdown against Yako, The Wicked Avatar takes Yugi's form. Yako says it's a manifestation of Yugi's hatred for his other self for being the true Game King and preventing Yugi from earning that glory himself. Yami almost falls for it, until Yugi briefly takes over and insists that he would never have been able to make so many new friends or broaden his horizons if it hadn't been for his other self.
- Theme Twin Naming: His given name means "Night Verse", as opposed to Gekkou's who means "Moon Verse" Doubles as Meaningful Name as it reflected how he was always under the shadows, the night's darkness as opposed to his brother who is always in the spotlight. Lampshaded by himself during his match against Yugi.
- Took a Level in Badass: He went from being ridiculed as a "bad copy" of Gekko before the beginning of the series to a Duelist that defeated Seto Kaiba. And he came close to beating Yugi as well, no less than three times. Even when he wasn't using the Wicked Gods, he still retained his prowess.
- Twin Switch: Sort of - Yako pulls a Grand Theft Me on his twin brother, Gekko, in order to test his new deck against Yugi.
- The Unfavorite: Yako believed he was the worse duelist out of the two. Pegasus described Gekko as a perfect duelist, while Yako was "an unfinished rough diamond." Subverted by the end of the series, where it is revealed that Pegasus saw the potential in Yako to be a great duelist, hence the "rough diamond" metaphor, while Gekko had "perfected" himself and was incapable of growing any stronger.
- Underestimating Badassery: He gives Jonouchi, a Duelist Kingdom finalist and Battle City semi-finalist, a ten dollar bounty to start, and it takes a while to go up to anything considerable. The same Jonochi who proceeds to wipe the floor with at least half his card professors.
- With Great Power Comes Great Insanity: Yako used to be a quiet, withdrawn young man. That all changed once he started creating the Evil Gods, which warped his grief over Pegasus' death into homicidal rage toward Yugi.
- Butt-Monkey: NOT Played for Laughs. Seriously, by the time the manga takes place, does the guy ever get something nice other than his victory against Ted Banias? His younger twin hijacks his body. Everyone he met on his way to Yako called him a traitor for siding with Yugi. Then he loses, and Richie gave him "The Reason You Suck" Speech. After Mokuba opens the way for him and Yugi, he was Punched Across the Room by Jounouchi (who mistakes him for Yako). When he reached the top, Yako laughed his ass off on how "The Perfect Duelist has fallen." Lastly during the final match between Yako and Yugi, Kaiba brushes it to his face that it's his fault that Yako become full of hatred and envy. Seriously, give the guy a break. All he wanted is to bring his twin's sanity back.
- Everyone Has Standards: He admits he wants to met Pegasus again, just like Yako... But not with sacrificing anyone. Depre, Richie, and Yakou all called him out on this.
- Foolish Sibling, Responsible Sibling: Responsible for Yako's insanity. The second he gained control over his own body again, he decided to assist Yugi because he felt responsible for everything that Yako has done.
- Identical Twin ID Tag: By the time R takes place. While both wear a maroon coat, Yako's gakuran are pink, while Gekko's are white. Also it's hard to notice but Yako actually has longer back hair than Gekko. Yako's back hair reached his waist while Gekko's back hair only reached his chest. Why Yugi doesn't notice this? Because he never sees Yako from the back, that's why. Their front hair are still the same.
- Polar Opposite Twins: Yakou has an unstable mind and still very dependent on Pegasus, (which drove him into becoming the Big Bad of R.) Meanwhile Gekko is mature, calm, gentle, and reasonable and grew independent when Pegasus disappeared. In their past, they are this too. Gekkou is cheerful and proud while Yako is gloomy and full of envy.
- Punched Across the Room: Courtesy of Jounouchi, who mistook him for Yako. When Yugi ran to him calling his name, Jounouchi realized he punched the wrong person and immediately apologized. Gekkou forgives Jounouchi the instant he apologized, because they are twins after all.
- Token Good Teammate: Among Pegasus' foster sons that appeared in R. See Everyone Has Standards above.
- Wham Line: "My growth is over". Yako takes that as an insult.
As a Whole
- Affably Evil: Though a few are quite arrogant, they're not nearly as devious or cruel as the Ghouls or Player Killers. It's worth noting that after the whole mess is over, they end up parting ways with the cast with little malice, if at all.
- The Chessmaster: They all put up a decent offensive with few weaknesses, using more advanced techniques then previous duelists used.
- Only in It for the Money: Their prime motivation. While other duelists wanted to duel Yugi for glory, they're only dueling him because he's worth over $100,000.
- Theme Naming: They're all named after microchips.
- The Worf Effect: Despite their impressive use of card combos and powerful monsters, most of them last but one or two chapters at most, much less than other duellists. Granted, this is what happens when you go against the very best duellists of the franchise.
- Worthy Opponent: They all come to view Yugi and Jonouchi as this.
Deschutes LewThe first duelist Yugi faces. His deck consists of high-defense monsters, with Castle Gate being his main card.
- Beard of Evil: Averted. He's a pretty nice guy when he's off the clock.
- Hoist by Their Own Petard: Enforced as his main offensive options: He uses Monster effects, Spell and Trap cards to make his opponent's monsters attack his opponent.
- Punch-Clock Villain: He doesn't take his position seriously, only doing what he was paid to do.
- Stone Wall: His main strategy.
- Warm-Up Boss: His role is limited to dueling Yugi and providing exposition on what he can expect if he beats him.
Tilla MookThe second duelist Yugi faces. She uses a Vampire deck, with Vampire's Curse being her main card.
- Break the Haughty: After Yugi beats her, her creepy persona completely fades away.
- Death-Activated Superpower: The effect of Vampire's Curse, Tilla's main monster, allows it to return from the Graveyard after being destroyed and become stronger -- after siphoning 1,000 of its duelist's Life Points, that is.
- Goth: Dresses in period clothes, uses vampires and has a holographic projection of a misty graveyard provide atmosphere for her entrance.
- Kiss of the Vampire: What Vampire's Curse does to Tilla after its return from the Graveyard looks like this, but without bloodshednote .
- Light Feminine and Dark Feminine: The dark to Maico and Reico's light.
- Night of the Living Mooks: Plays a rather powerful undead deck, focusing on Vampire Monsters.
- Nightmare Fetishist: She seems to enjoy getting bit by her Vampire's Curse card just a little too much.
- You Are in Command Now: Jonouchi gives her the coveted black duel disk, marking her as the best duel professor.
Klamath OslerThe first duelist Jonouchi faces. He uses an Insect deck, with Antlion being his main card.
- Anime Hair: Looks like Astro Boy
- Animal Motifs: Bugs and worms.
- Big Creepy-Crawlies: Especially creepy.
- Butt-Monkey: Among the Card Professors, he's clearly on the low-end of the totem pole, drawing the short straw when it came time to decide who would guard which route and getting flustered as Jounouchi starts gaining the momentum on him. In-between omake panels also confirm this, as Kirk Dixon creams him in a mini-robo battle.
- Hoist by His Own Petard: Played with near the end of his duel against Jonouchi.note
- The Napoleon: Quite short and acts like he has something to prove.
- Pet the Dog: Turns out he gathered up everyone's school supplies after the ordeal was over and sheepishly hands them over.
Kirk DixonYugi's third opponent. He uses a Machina deck, with Machina Force being his main card.
- Combat Pragmatist: Knew that Yugi's confidence could be shaken if his friends were taken out of the picture, so he laid traps to separate Yugi from Honda and Jonouchi.
- Crazy-Prepared: Rigged his entire area with booby-traps in the hopes that at least one of them would be triggered.
- Four Eyes, Zero Soul: Wears glasses and is absolutely ruthless.
- Hoist by His Own Petard / Laser-Guided Karma: After being beaten by Yami, he steps on one of his own traps and is flung into the basement. Worth noting that he claimed that Jounouchi and Honda ended up there. They did...after Jounouchi beat Klamath and they were making their way back up to the top, noticing Kirk falling into a dumpster.
- Kick the Dog: Taunts Yugi about Jounouchi and Honda ending up the trash after they fell for one of his traps
- Killer Robot: His deck's theme.
- Pet the Dog: Salutes Yugi's group after Yako's defeat, making for a stark contrast from his earlier behavior.
Pete CoppermineJonouchi's second oppoent. He uses a Mutant deck, with Mutant Mindmaster as his main card.
- Anime Hair: Heavy Metal-style.
- Body Horror: The theme of his deck.
- The Gadfly: Spooks Jonouchi on sight and overall seems to enjoy practical jokes.
- Goth: Of a cyber-punk variety. He wears tight black clothes with heavy eyeliner, wild hair and uses cards based around mutations.
Maico KatoYugi's fourth opponent. She uses forest-themed cards, with Green Baboon, Defender of the Forest as her main card.
- Cool Old Lady: Plays Duel Monsters with her grandchildren and planned to use her payment to buy them more cards. She also gave Yugi a run for his money.
- Friend to All Children: Loves her grandchildren dearly.
- Handicapped Badass: She's wheelchair-bound, but her skill at Duel Monsters rivals Yugi's.
- Silk Hiding Steel: She doesn't act like a typical antagonist duelist and her strategy is based around stealth.
- Token Good Teammate: She's not after Yugi for the status and while she is in it for the money it's to buy nice gifts for her grandchildren. She also is extremely polite to Yugi before and after she loses, taking her loss well instead of freaking out unlike most card professors.
Mendo CinoJonouchi's third opponent. He uses a Mantis deck, with Dreadscythe Harvester as his main card.
- Animal Motifs: Mantises
- Big Creepy-Crawlies: And they breed, thanks to his Mantis Egg card.
- Underestimating Badassery: Considered Jonouchi paltry due to his bounty being only $500. When Jonouchi beat him, he was shocked that such a skilled duelist would be so undervalued.
Willa MetteA card professor that Seto Kaiba duels. He uses a Dragon deck, with White-Horned Dragon being his main card.
- Break the Haughty: Was hoping to do this to Kaiba. It backfired.
- Bullying a Dragon: He targets Kaiba specifically. It goes about as well as you'd expect.
- Man of Kryptonite: His deck was specifically constructed to counter Kaiba's strongest cards.
- Underestimating Badassery: He believes that the game's Power Creep, with an increased focus on special abilities and swarming, has made Kaiba's usual strategies (Crush Card and Blue-Eyes) completely obsolete. Kaiba proves him wrong on all accounts.
Ted BaniasA card professor that Gekko Tenma duels. He uses a Beast/Beast-Warrior deck, with Assault Lion being his main card.
- Anime Hair: He resembles Sasuke Uchiha
- Break the Haughty: Assumed that he could beat Gekko based solely around the fact that he didn't have any monsters out. Gekko showed him that he's so good he doesn't need monsters.
- Good Eyes, Evil Eyes: Narrow, with small pupils and pronounced tear troughs.
- Made of Iron: Bandit Keith kicks him through a glass panel, knocking him out...and he pops up at the story's credit end no worse for the wear.
- Smug Snake: Gloated over the fact that Gekko wasn't drawing any monster cards. Turns out Gekko didn't need any to beat him.
Reiko KitamoriJonouchi's fourth opponent. She uses a Puppet Chess deck, with Puppet King being her main card.
- Badass Pacifist: It's somewhat Deconstructed in that her pacifism is due to being timid more than anything, and Jounouchi can't really get into the duel because of it.
- Beware the Nice Ones: Her deck's main strategy is defending and Deck Destruction through Battlefield Tragedy note , which can be played in multiples. Jonouchi really only won because he got Reiko to go on the offensive.
- Expy: Reiko may be this for Shizuka down to their similar faces, hair, and personalities. She also duels Shizuka's big brother, Jonouchi.
- The Friend Nobody Likes: The only reason she was recruited was to help stall for time.
- Nice Girl: Very sweet, to the point that she refrains from attacking until Jonouchi presses her.
- Token Good Teammate: The other one. She's only part of the occupation of Kaiba Corp because she was forced to come by the other professors and has to be chased down for her duel.
- Villainous Crush: She's implied to have one for Jonouchi.
Depre ScottYugi's fifth opponent and one of Pegasus' adopted sons. He uses a Cosmic deck, with Greed Quasar being his main card.
- Ambiguous Disorder: In the original version, he speaks with a strange form of voice, almost akin to an alien, and completely breaks down after being defeated by Yugi, to the point where Richie has to call in Security to get Depre out of the dueling arena. There's something off about him.
- Asskicking Equals Authority: He's one of the best Card's Professors and the last faced.
- Co-Dragons: Depre and Richie are implied to be this to their adopted brother Tenma.
- Crazy-Prepared: He's well-aware that his deck's best strategies hinge on Cosmic Space and makes sure to have back-up copies in his hand.
- Knight of Cerebus: His disturbing demeanor and rather powerful deck establish him as one, as he has Yugi on the ropes throughout their entire duel.
- Power of the Void: His Cosmic Space field spell. It's essentially the vacuum of space that forces Life Star Counters onto a monster equal to its Level and drains them on every End Phase. If the number of counters goes to zero, the monster is destroyed note
- Starter Villain: For Yugi. He's the first villain Yugi takes on with his own deck rather than one shared with the Pharaoh. Unlike most however, he's legitimately dangerous, having previously been ranked #1 before Richie defeated him.
- Those Two Guys: Him and Richie.
- Underestimating Badassery: He assumes regular Yugi is no match for him and insists Yami come out and deal with him personally. Yami lampshades this, only coming out to talk up his partner with Yugi then managing to turn things around.
- Villainous Breakdown: A more serious example than some. Depre breaks down crying after Yugi defeats him, wailing about how he just wanted to see Pegasus one more time, and the moment is played rather tragically.
Richie MercedGekko's second opponent and one of Pegasus' adopted sons. He uses a Warrior deck.
- Achilles' Heel: He doesn't seem to run any high-level monsters, focusing more on damage effects and traps...which rends his deck vulnerable to Angel O7, which negates all other monster effects, and does jack-squat against The Wicked Eraser, which, as a God card, is immune to such effects, rendering Richie's traps useless and giving the Eraser free ATK to easily run over his monsters.
- Anti-Magic: His deck doesn't exactly follow these lines, but his strategy of disruption through cards like Theft Whip and Mirage call it into mind, as he is able to disable his opponent's combos, leaving them helpless against his monsters, or even turn their strength back at them.
- Asskicking Equals Authority:The best Card Professor, to the point that it took an evil God Card to take him down.
- Avenging the Villain: Defied with Depre, as Richie declines dueling Yugi, but played straight with Pegasus as Richie desires to crush Gekko for betraying them.
- Anime Hair: Just like Yami Malik's.
- Co-Dragons: Richie and Depre are implied to be this to their adopted brother Tenma.
- Cowboy: The theme of his deck.
- The Gunslinger: All of his monsters use guns. He himself is shown with a holstered revolver in an omake panel.
- Knight of Cerebus: While all the other card professors were beaten within a few turns, Richie managed to beat Gekko himself.
- Those Two Guys: Him and Depre.
- Trap Master: The other aspect of his Deck. He doesn't use as many traps as Rishid does, but the ones he does use have fairly potent effectsnote , and in the end, it is his usage of trap cards that defeats Gekko.
- Villainous Friendship: He claims otherwise concerning Depre, but it's worth noting that in a flashback where Richie lost to Gekko, Depre is the only one supporting Richie, and the two are oftentimes seen together.
- Weak, but Skilled: Of the three monsters he's seen using, the highest ATK value is Pierce Musketeer with 1700. But at the same time, all of his monsters have very tricky effects, in particular Twin Gunfighter being able to inflict 1600 damage should it successfully engage in battle.
- The Worf Effect: Gets hit with this to establish Bandit Keith's prowess with The Wicked Eraser.
