History Characters / YuGiOhR

* UnderestimatingBadassery: He gives Jonouchi, a Duelist Kingdom finalist and Battle City semi-finalist, [[ComicallySmallBribe 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.

* ButtMonkey: NOT PlayedForLaughs. 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 [[GrandTheftMe 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 TheReasonYouSuckSpeech. After Mokuba opens the way for him and Yugi, he was PunchedAcrossTheRoom 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.
* EveryoneHasStandards: He admits he wants to met Pegasus again, just like Yako... But not with sacrificing anyone. Depre, Richie, and Yakou all call him out on this, believing that he has betrayed them, but considering what ''they're'' hoping to do, along with the general MoralMyopia on display, it's hard to side with them.

* IdenticalTwinIDTag: 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.
* LightIsNotGood: While under Yako's control, Gekko uses a Seraphim deck, which are all light-themed Fairy monsters. Said monsters are ultimately nothing more than Tribute fodder for ''The Wicked Dreadroot''. His proper ace monster, ''Angel 07'' on the other hand, [[LightIsGood is actually on the side of good.]]

* PerfectionIsStatic: The true meaning behind Gekko's status as the "perfect" duelist, a moniker used by Pegasus, Yako, and their peers, the card professors. Gekko is able to pull out "perfect" dueling strategies, while his younger brother Yako is a "rough, unpolished diamond" who is constantly in Gekko's shadow. Gekko's status isn't to be reckoned with either, as he is presented as an undefeatable duelist by the card professors and his winning streak continues to grow when he teams up with Yugi to stop his brother's maniacal plan. [[spoiler:[[DefeatingTheUndefeatable The streak is then broken by Ritchie]], the top-ranked card professor in the manga, which ends up breaking his resolve]]. When Yako is confronted by Gekko on the roof of Kaiba Corp, Gekko finally realizes what he meant by him being the "perfect" duelist; [[spoiler:while Gekko ''did'' win against the other card professors in the past, the victories have always been by small margins. Over time, the peers he defeated previously continued to grow and improve, eventually closing the gap between their skills. Gekko then states that he's not "the" perfect duelist, but a "perfected" one, and he will never grow]]. This realization only infuriates Yako, furthering his resolve to try and salvage his plan.
* PolarOppositeTwins: Yakou has an unstable mind and still very dependent on Pegasus, (which drove him into becoming the BigBad 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.

* ThemeNaming: Possibly unintentional, but Gekko also shares his name with a microprocessor (the IBM-made Gekko CPU used in the Platform/NintendoGameCube), which contrasts with the Card Professors who are all named after Intel processors.

* WhamLine: "My growth is over". Yako takes that as an insult.

* OnlyInItForTheMoney: Their prime motivation. While other duelists wanted to duel Yugi for glory or to kill him, they're only dueling him because he's worth over $100,000.

* RunTheGauntlet: The intended plan was to have Yugi run though all thirteen Card Professors to wear him down, but thanks to the intervention of Jonouchi and Kaiba they take out half of them as well.
* ScientificAndTechnologicalThemeNaming: The Card Professors in are named after production codenames of microchips (Mendo Cino from Mendocino[[note]]the 300 [=MHz=] P6 Intel Pentium II Centrino chip[[/note]] and Kirk Dixon from Dixon[[note]]the 333 [=MHz=] 1.6V Intel Pentium II chip[[/note]], for example), which explains why [[AerithAndBob some of them are much more "unique" than others]]. This overlaps somewhat with LocationThemeNaming, as many of those codenames were originally taken from the locations of various Intel plants (Tilla Mook is derived from Tillamook[[note]]the Embedded 266 [=MHz=] Intel Pentium MMX chip[[/note]], Oregon, and Willa Mette is named after the Willamette[[note]]Intel's 1.5 [=GHz=] P7 Pentium IV[[/note]] River from the same state).
* TheWorfEffect: 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.

* KissOfTheVampire: What Vampire's Curse does to Tilla after its return from the Graveyard looks like this, but [[BloodlessCarnage without bloodshed]][[note]]-- then again, it's a hologram[[/note]].

* NightOfTheLivingMooks: Plays a rather powerful undead deck, focusing on [[OurVampiresAreDifferent Vampire Monsters]].

* YouAreInCommandNow: [[spoiler: Jonouchi gives her the coveted black duel disk, marking her as the best duel professor.]]

* CombatPragmatist: Knew that Yugi's confidence could be shaken if his friends were taken out of the picture, so he [[spoiler: laid traps to separate Yugi from Honda and Jonouchi.]]

* HoistByHisOwnPetard / LaserGuidedKarma: [[spoiler: 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.]]

* CoolOldLady: 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.

* AnimalMotifs: Mantises

* HoistByHisOwnPetard: His ''Labor Pain'' card [[note]]A Continuous Spell that requires both players to pay 1000 LP to Normal Summon[[/note]] acted as a decent floodgate card at first since he'd cleared Jounouchi's field and could use ''Mantis Egg'' to bring out tribute fodder with no cost, but once Dreadscythe Harvester was destroyed, Cino was on the receiving end of his own Spell, losing his own LP as he tried to set up a defense.

* SmugSnake: Gloated over the fact that Gekko wasn't drawing any monster cards. [[spoiler: Turns out Gekko didn't need any to beat him.]]

* BewareTheNiceOnes: Her deck's main strategy is defending and Deck Destruction through ''Battlefield Tragedy'' [[note]] A card that mills a player's deck for five cards whenever they attack[[/note]], which can be played in multiples. Jonouchi really only won because he got Reiko to go on the offensive.

* TokenGoodTeammate: 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.

* PowerOfTheVoid: 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]]It's worth noting that in the modern game, such a card would automatically disable every Xyz and Link Monster as they lack levels.[[/note]]

* ThoseTwoGuys: Him and Richie.

* AchillesHeel: 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 [[PowerNullifier negates all other monster effects]], and does jack-squat against ''The Wicked Eraser'', which, as a [[OlympusMons God card]], is [[NoSell immune to such effects]], rendering Richie's traps useless and giving the Eraser free ATK to easily run over his monsters.

* AsskickingLeadsToLeadership: The Number One Card Professor, to the point that it took an evil [[GameBreaker God Card]] to take him down.

* ThoseTwoGuys: Him and Depre.

* VillainousFriendship: 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 [[ThoseTwoGuys two are oftentimes seen together]].

!! Cedar Mill

* CripplingOverspecialization: His greatest weakness is by using a deck that specializes in countering the opponent. In the duel against Yugi, his LIGHT Deck's an ace monster, Tualatin, destroys all face-up DARK Attribute monsters and his opponent can't summon monsters of the same Attribute. While it seems intimidating at first, he comes up short when Yugi uses a Counter Trap that allows him to negate the effect of Masumi's card, it allows him to Special Summon Van'Dalgyon the Dark Dragon Lord from his hand and destroy Tualatin. With his ace monster gone, he is unable to draw a card that can help defend himself from Yugi's dragon, and loses the following turn.

* MeaningfulName: His name roughly translates to "100 fields," which reflect how he is a master of several different deck types to counteract his opponent.
* ThemeNaming: Like other characters in ''R'', his ace monster's name, Tualatin, takes after a codename of a microprocessor. Tualatin originates from the Tualatin codename of Intel's 1.266 GHz Flip Chip Pin Grid Array　(FCPGA2) Pentium III (P3-850) microprocessor, named after the Tualatin Valley and Tualatin River in Oregon.

!!'''Yako Tenma (天馬夜行;Tenma Yakōu)'''

-->'''Jonouchi''': *thinking to himself* I hate you, Yako...

!!'''Gekko Tenma (天馬月行;Tenma Gekkō)'''

* ThemeNaming: They're all named after production codenames of microchips.

* LightIsNotGood: In his only appearance, he uses a LIGHT-Attribute deck to counter Yugi's DARK-based deck, using a number of Fairy/Angel monsters, but he is no saint. He also is unsuccessful in defeating Yugi.

* MeaningfulName: His name roughly translates to "100 fields," which reflect how he is a master of several different deck types to counteract his opponent. For example, his LIGHT Deck has an ace monster known as Tualatin, which destroys all face-up DARK Attribute monsters and his opponent can't summon any of the same Attribute.
* ThemeNaming: Like other characters in ''R'', his name takes after a codename of a microprocessor, more specifically, his ace monster, Tualatin. Tualatin is one of the codenames of the Intel Pentium III chip.

* TheUnFavorite: 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.

* SpannerInTheWorks: An unintentional example, [[spoiler:but him being the last Card Professor ends up helping the heroes once Yami Yugi defeats him, as it activates a last-ditch stop order Kaiba built into the Duel Ring Server, stopping Pegasus' resurrection.]]

* {{Jerkass}}: He's not the most pleasant guy to be around, having no mercy towards Bandit Keith ([[KickTheSonOfABitch Keith's actions notwithstanding of course]]), being very hostile to his opponents, boasting during his duel with Gekko, and bluntly telling Yugi that he will not be progressing any further [[spoiler:after Gekko is defeated]].

* CloningBlues: 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.

* SenpaiKohai: Yako is Pegasus' kohai. One of them.

* KnightOfCerebus: While all the other card professors were beaten within a few turns, [[spoiler: Richie managed to beat Gekko himself.]]
* LaserGuidedKarma: After his beatdown of Keith and subsequent defeat of Gekko, Richie ends up ambushed by Keith and loses to the Eraser. To add insult to injury, Yako specifically ''planned'' this, meaning that in the end, for all of Richie's bluster and skills, he was nothing but a pawn for Pegasus' resurrection... a resurrection which ends up failing completely and utterly. Suffice to say, his final scene showcases him distant and humbled.

* TookALevelInBadass: He lost to Gekko constantly (read: all the time) when they were younger. After many duels of training and rising in the ranks of the Card Professors, Richie finally manages to defeat Gekko.

* TheUnfettered: In his eyes, nothing, not even hurting innocent people, should get in the way of the ambitions of reviving Pegasus. Gekko calls him out on it, but Richie doesn't care. He later states that this is why he won their duel; Gekko was too focused on protecting Yako, but Richie's will to save Pegasus, when he had nothing left to lose, gave him in the edge. Yugi is utterly flabbergasted with this statement.

* BigBad: of ''Manga/YuGiOhR''

* EveryoneHasStandards: 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.
* FoolishSiblingResponsibleSibling: 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.

* RedemptionDemotion: After regaining control of his body, Gekko tears up the cards Yako has him use which included a copy of the powerful ''Wicked God Eraser''.
* TokenGoodTeammate: Among Pegasus' foster sons that appeared in R. See EveryoneHasStandards above.

* AsskickingEqualsAuthority: He's one of the best Card's Professors and one of the last ones faced. He was in fact, Number One in their rankings the year prior before Richie took the spot.

* AsskickingEqualsAuthority: The Number One Card Professor, to the point that it took an evil [[GameBreaker God Card]] to take him down.

* SempaiKohai: Yako is Pegasus' kohai. One of them.

Yako's older brother.

* ThemeNaming: They're all named after microchips.

* TheGambler: Implied by Bandit Keith's comments that Ted owes him money from losing the games they played while waiting for Yugi to show up. The bonus illustration from his debut chapter also features Ted playing Mahjong.

* AmbiguousDisorder: 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.

* OnlyInItForTheMoney: Their prime motivation. While other duelists wanted to duel Yugi for glory, they're only dueling him because he's worth over $100,000.

* HoistByTheirOwnPetard: [[EnforcedTrope Enforced]] as his main offensive options: He uses Monster effects, Spell and Trap cards to make his opponent's monsters attack his opponent.

* AnimeHair: Looks like Manga/AstroBoy

* BigCreepyCrawlies: Especially creepy.

* SilkHidingSteel: She doesn't act like [[ArrogantKungFuGuy a typical antagonist duelist]] and her strategy is based around stealth.

* UnderestimatingBadassery: 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.

A card professor that Seto Kaiba duels. He uses a Dragon deck, with ''White-Horned Dragon'' being his main card.

* BreakTheHaughty: Was hoping to do this to Kaiba. It backfired.

* ManOfKryptonite: His deck was specifically constructed to counter Kaiba's strongest cards.

* AnimeHair: He resembles [[Manga/{{Naruto}} Sasuke Uchiha]]

* PowerOfTheVoid: 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]]It's worth noting that in the modern game, such a card would automatically disable every Xyz and Link Monster as they lack levels.[[/note]]

* CoDragons: Richie and Depre are implied to be this to their adopted brother Tenma.

* {{Jerkass}}: He's not the most pleasant guy to be around, having no mercy towards Bandit Keith ([[KickTheSonOfABitch Keith's actions notwithstanding of course]]), being very hostile to his opponent's, boasting during his duel with Gekko, and bluntly telling Yugi that he will not be progressing any further [[spoiler:after Gekko is defeated]].

[[/folder]]

Yugi's fifth opponent and one of Pegasus' adopted sons. He uses a Cosmic deck, with ''Greed Quasar'' being his main card.

* AsskickingEqualsAuthority: He's one of the best Card's Professors and the last faced.

Gekko's second opponent and one of Pegasus' adopted sons. He uses a Warrior deck.

* AsskickingEqualsAuthority:The best Card Professor, to the point that it took an evil [[GameBreaker God Card]] to take him down.

The last card professor Yugi meets prior to confronting Yako.

!!'''Yako Tenma (天馬夜行;Tenma Yakōu)'''

* InformedAbility: They're considered elite duelists, but all [[spoiler: but one]] of them are beaten by Yugi, Jonouchi, Kaiba, and Gekko.

* TheWorfEffect: Despite their impressive use of card combos and powerful monsters, their statuses as professors is undermined by a group of teenage boys...who are granted some of the top duelists in the world.
