->''I made a wish on that puzzle... for friends I could count on... friends who could count on me! No matter what!''

Loosely following the [[Manga/YuGiOh original manga]] made by Kazuki Takahashi (though following it closely at ''very'' specific points), there were actually two Franchise/YuGiOh anime series: [[Anime/YuGiOhFirstAnimeSeries The first anime]], which covers the first seven volumes of the manga (though with ''very'' major changes, including making Kaiba a more frequently recurring villain), which was made by ToeiAnimation; and this one, the second series, ''Yu-Gi-Oh: Duel Monsters'', was produced by NAS (animated by StudioGallop) and is adapted from volume 8 (with a bit of re-imagined elements from the earlier volumes) onward, rather loosely in a lot of places (and featuring several {{Filler Arc}}s).

This adaptation is given the subtitle "Duel Monsters" (taken from {{Konami}}'s early GameBoy game based on the manga, with the same title/logo but with Toei's artwork on the cover) to demonstrate the elevated prominence of the card game compared to the manga and first series anime -- adding duels that are not originally in the manga and changing parts of the story in order fit the addition of duels and cards. It was sponsored by {{Konami}} as an successful attempt to remain dominant of the license to the card game, after it stripped it away from {{Bandai}}, which failed to retain the license of capitalizing on the manga's card game with Toei's movie and anime.

This second series is probably the reason why you are reading this, since it was the [[AdaptationFirst one who made the series popular as it today]].

There's a huge amount of video games based on this series, the most famous of which is ''VideoGame/YuGiOhReshefOfDestruction''. It spawned a movie called ''[[Anime/YuGiOhTheMoviePyramidOfLight The Pyramid of Light]]''. This version of Yugi and his alter ego return in the ''Anime/YuGiOhTenthAnniversaryMovie'' that [[BatFamilyCrossover teams him up with Juudai and Yusei.]]

This show in particular is also responsible for the creation of ''TheAbridgedSeries'' genre of internet videos, with ''WebVideo/YuGiOhTheAbridgedSeries''.

This series has [[TearJerker/YuGiOh Tear Jerker]], [[NightmareFuel/YuGiOh Nightmare Fuel]], [[AwesomeMusic/YuGiOh Awesome Music]], and [[Characters/YuGiOh Character Sheet]] pages.

The dub is now [[http://www.hulu.com/yu-gi-oh available on]] {{Hulu}}.

----
!!This show provides examples of:

[[foldercontrol]]

[[folder:A - M]]
* AbandonedWarehouse: Bandit Keith dueled Yugi in an abandoned warehouse that had its own Duel Monsters arena.
* AbortedArc: Beginning in Season 2 of the anime, the stone tablet that would continue to be a plot point for the rest of the series showed Kaiba and Yugi dueling in ancient Egypt. A vision from Isis to Kaiba showed him a vision of the battle. Later in Season 3 another vision of this battle is shown, but it's completely different from the vision showed before. The battle is seen first-hand in Season 5, and is rather underplayed given the amount of foreshadowing and importance given to it before. Furthermore, though they differed greatly both visions showed Kaiba was quite clearly the Pharaoh's enemy, but in Season 5 he's completely loyal and the only reason the battle occurs is because he gets possessed.
** This can be attributed to ExecutiveMeddling, as Kazuki Takahashi never got to flesh out the story with Seto and Kisara the way he wanted, and rebelling against the Pharaoh was probably intended to be a larger plot point for his story.
*** In the original version of the anime, Kaiba and Atem even [[LampshadeHanging point out]] that the duel was completely different from what they expected. Atem handwaves it, saying the memory world is probably not an accurate representation of what really took place.
** When it first appears, the tablet does not have Kaiba holding the Millennium Rod--it's just a generic staff, and he doesn't have it in the vision Isis shows Kaiba either. Later the fact Kaiba has the Rod on the tablet becomes a major plot point, and over time the image on the tablet changes to the point it is quite clearly the Millennium Rod.
* AbsurdlyHighStakesGame: Shadow Games and Duel Monsters. The world is frequently at stake (in the dub).
** Season 4 has the characters losing their soul if they lost, meaning effectively the loser was left with an empty shell of a body
* AbusiveParents: Gozaburo Kaiba, Marik and Isis's father. Also, Jounouchi's father...
** In Jonouchi's case, his abusive father is only ever mentioned and shown in the [[Manga/YuGiOh original manga]].
* AccentAdaptation: In the 4Kids dub, Joey/Jonouchi was given a Brooklyn accent to represent his plain speech patterns in the original. On the other hand, Ryou Bakura was given a British accent to reflect his politeness. It's hard to get across the dialectical differences in Japanese into a dub, hence the altered accent as a way to convey that.
* ActingUnnatural: Since he and Anzu/Tea are stowaways on the ship to Duelist Kingdom (and Joey wasn't really supposed to be there either), Honda/Tristan advises everyone to "act casual" going past the guards...and then marches past looking ridiculously uncomfortable and suspiciously.
* AdaptationDyeJob: While not as bad as the Toei anime, this anime introduces the ''Blue'' Blue-Eyes "White" Dragon and the Black Magician is bright purple (he's black with a blue/purple hue in the manga).
** Possibly why the Black Magician is changed to Dark Magician in the dub.
** In the loose anime adaptation of the Millennium World saga, the Black Magician Girl (Mana's Monster Spirit in the Shadow RPG) has her usual Pegasus-produced modern card game skin color. In the manga, her skin is [[AmbiguouslyBrown]]. Furthermore, some of the Monster Spirits that actually appear in Pegasus's ''Duel Monsters'' game actually look a bit different than their actual Monster Spirit incarnations as well. In the anime, however, all Monster Spirits look the same as their mainstream artwork for the TCG.
* AdaptationExpansion: The Big 5. In the manga they were just faceless goons in the shadows who cooperated with Pegasus, while in the anime each was given a name and a clear personality, primarily during the Virtual World arc.
* AdaptationInducedPlotHole: Skipping the first seven volumes and cramming the development into Duelist Kingdom, along with dozens of added anime-exclusive details and the removal of certain details from the manga, creates exclusive plot holes for the anime that weren't present in the manga. Notably, [[http://ygocanonshuffle.wordpress.com/2011/03/23/episode-1b-yami-yugi-reveal-and-the-mystery-of-grandpa-being-injured-by-a-card-game/ grandpa getting severely injured through a card game for no rational explanation]], Yugi's puzzle receiving the powers of [[http://ygocanonshuffle.wordpress.com/2012/01/27/dm-episodes-14-15-fire-fire-fire-fire-fire-fire-fire-fire-fire-fire-fire-fire-fire/ protection from fire]] and [[http://ygocanonshuffle.wordpress.com/2012/01/07/dm-episodes-12-5-13-yami-bakura-the-differences/ putting souls back into their original bodies]] (which defeats the purpose of his whole Duelist Kingdom trip to begin with), and of course, the Duel Stadiums creating [[http://ygocanonshuffle.wordpress.com/2011/04/28/why-i-hate-the-duel-platforms/ logical fluffs]] that also weren't present in the manga, which had Duel Boxes.
** Bakura's Ring being able to summon monsters outside of a game in the anime.... and laser beams. What's the point of playing a game to kill your enemies when you could just use that, anime? He calls the random summoning of monsters a game in the Japanese version, even though it doesn't resemble anything close to a game at all. Also, the anime never explains why Dark Bakura was after Mokuba for the key to Kaiba Corporation's safe (he was acting as if he had performed a HeelFaceTurn in the manga, helping Honda when he was trying to save Mokuba at night). The dub actually made a little more sense, with him being after his body instead, even though it still created a plot hole (Bakura being the ChosenOne for the Millennium Ring and the Shadow RPG). Granted, the anime version of Duelist Kingdom had way too many instances of ''making no sense''.
** Pegasus somehow finding out about Kaiba's defeat at the hands of Yugi during that Not-Death-T first episode, in which the only witnesses to the duel are Jonouchi and Mokuba. Makes more sense in the manga, where there was an entire audience of Kaiba fanboys overlooking its equivalent to the first episode match.
** You know how the anime never explains how Bakura got the ring back in Millennium World? [[http://c.mhcdn.net/store/manga/6067/23-219.0/compressed/l005.jpg The manga does]].
** Pegasus gives Mokuba a Penalty Game WITHOUT playing a game. (In the manga, he captures Mokuba's soul off-panel.) The anime clearly broke one of the main rules of the Millennium Items - you need to beat an opponent at a game before you can MindRape them. If Pegasus could trap souls at a whim, why on Earth would he ever play a game with anyone in the first place? Taking over Kaiba Corp should be a snap. Heck, taking over the WORLD should be a snap.
*** Related to that, in the manga right before his duel with Pegasus, when the soulless Mokuba is brought out before everyone Kaiba is horrified and surprised to see that his brother's soul has been stolen, since as stated it happened to Mokuba off-panel, presumably while Kaiba was dueling Yugi. The anime kept this scene intact... despite the fact that Pegasus stole Mokuba's soul right in front of him just a few episodes ago, yet he still acts like this is the first time he's seen Mokuba in a soulless state.
** It's safe to say that most of the things that the Abridged Series takes pot-shots at are anime exclusive, if not [[CutAndPasteTranslation dub exclusive]].
* AerithAndBob: By-product of dubbing. 4Kids gave new names to only ''some'' of the characters, resulting in completely typical sounding names like Joey, Tristan and Duke appearing alongside characters like Yugi, Seto, Mokuba, and Bakura. Somewhat jarring when none of the cast themselves [[UnusuallyUninterestingSight ever notice or mention it.]] Not at all helped by the fact that certain people, like Tea, ''still'' had somewhat unusual sounding names after the fact.
** Joey makes sense as a shortening of Jounouchi, and Honda's name might have been changed to avoid confusion with the car company...but where the heck does one get Tea out of Anzu anyway?
** In all honesty though, names like Yugi, Seto, Mokuba, and Bakura sound unusual to Japanese ears as well.
* AgentPeacock: Pegasus is this.
* AllegedLookalikes: No-one ever seems to see a difference between short, moe, [[TaremeEyes Tareme]]-eyed, soft-voiced Yugi and his not-quite-so-short, bishonen, [[TsurimeEyes Tsurime-eyed]], deep-voiced [[SuperPoweredEvilSide alter ego]]. Some fans have tried to explain the (apparently not so) obvious changes as audio-visual cues to the audience that do not actually exist in-universe. Since every once in a blue moon somebody ''will'' mention one of the changes in passing, this explanation has not been widely accepted. Maybe the others just can't stop staring at the hair.
** Regarding the height difference: probably because in the manga, which is the anime's source material (for the most part), Dark Yuugi is the same height as the normal one. And regarding the vocal difference, the extremely deep voice is only in the dub. The Japanese voice actor portrays Dark Yuugi as a more confident-sounding Yugi, which the manga stated more than once to be the case. And in the manga, the other characters definitely noticed the demeanor change immediately. It's just the anime's flaw for skipping seven whole volumes of material where the characters are getting used to their friend having a split personality.
* AloofBigBrother: Seto Kaiba.
** Zigfried von Schroeder may as well count, too.
* AlternateUniverse: The PS2 game ''Duelists of The Roses'', which takes place during The War of The Roses. Yugi and Yami are two separate people (although they usually are, in the games), and Yugi's friends represent the Lancastrians, while Kaiba and crew are the Yorkists. Some fans have actually admitted to ''reading up on the actual historical events'' after playing the game!
** ''VideoGame/YuGiOhReshefOfDestruction'' is this to the anime's season 4.
* AlternativeForeignThemeSong: As with all the anime that 4Kids dubs, the English opening is different from the Japanese opening. You can listen to it [[http://www.youtube.com/watch?v=HeRC0Cu-QOQ here]].
* AmuletOfConcentratedAwesome: Yugi's Millennium Puzzle given that it has the soul of a 3,000 year old Pharaoh in it and tends to be generally badass when it takes over Yugi's body. Actually, most of the Millennium Items in general fit this trope.
* AncientEgypt: A large chunk of the characters and [[MacGuffin artifacts]] come from this time period. It was also the scene of the final Shadow Game.
* AngelFaceDemonFace: The differences in appearance between Yugi, Bakura, and Marik and when their [[SuperpoweredEvilSide Yami]] sides take over. [[SubvertedTrope Though]] Yami Yugi [[AntiHero isn't]] the most demonic per se, and normal Marik [[BigBad isn't the most angelic]].
* AngryEyebrows: Yugi --> Atem.
* AnimationAnatomyAging
* AnimationBump: As a general rule of thumb, the more important episodes are animated with an art style which is superior to that seen during other episodes. The opening/closing sequences are also animated using a cleaner animation style.
** The last and most important arc (Millennium World), however, takes a nose dive into [[OffModel QUALITY]] and looks absolutely terrible compared to the rest of the series. Though the lack of height difference between Yugi and Dark Yugi during the Ceremonial Battle is much more accurate to the manga, despite the animation being bad.
** Season 3 has one of the best quality in the series to the point that almost everyone,[[EspeciallyZoidberg especially Yugi]], becomes Moe-like. Though it start to go off-model after the final duel with Yami Marik.
* AnimeHair: Yugi. All the supporting characters tend to be trying to outdo each other in outlandish hairstyles, at the same time.
** Excluding the Kaiba brothers, though. Theirs seem normal enough, for a cereal bowl mullet and a black mop.
** Lampshaded in the Abridged Series:
--->'''Random Mook (to Yugi)''': Wow. Your hair's crazy enough for two people!
--->'''Head Mook''': Attention, Duelists! My hair is now an internet phenomenon!"
* ArcWords: In the Japanese version at least, "Something that you can see, but something that can't be seen" gets repeated quite a lot at least early on. Originally it referred to the Sennen Puzzle, but it's used to refer to many different things since then by slightly altering the way the line is interpreted.
* ArtifactOfDoom: Millennium Items tend to give their owners awesome PsychicPowers of some sort. However, more often than not, they will also harbor or lead to the development of their owners' {{Super Powered Evil Side}}s, or at least contribute to their {{Face Heel Turn}}ing.
** Technically, with 4 items to 3, there are more benign or beneficial cases - the necklace, the key, the scales and the puzzle against the eye, the ring and the rod.
* ArtifactTitle: "Yu-Gi-Oh" means "Game King." The anime (or rather, Konami) goes out of its way to remove every non-card game element of the manga and/or make them card game-related, in order to make it seem as if Duel Monsters is the only game worth existing. Therefore making the anime version of Yugi seem like "The King of ''a'' Game."
** In-universe, the Duel Disks pretty quickly began resembling things other than disks.
* ArtisticLicenseHistory: Beyond the parts that [[SadlyMythtaken never would have been accurate to begin with]] (Obelisk as a God, the costumes, the fact that most of the characters in the Memory World are going around with their own hair), other AnachronismStew mistakes crop up - such as people using what seem to be steel or iron swords during what should have been the ''Bronze'' Age. Doubly the case for the dubbed version. Five thousand years ago - 3000 BCE - would have been ''before the pyramids were built.'' Horses weren't introduced to Egypt until around 1700-1550 BCE.
* ArtShift: In the first episode. Once Yami defeats Kaiba and performs a mind crush on him, his face becomes less angular and his eyes gain pupils.
* AscendedExtra: The Big 5, Gozaburo Kaiba, Johnny Step, and Professor Hopkins.
* AscendedMeme: The nicodouga phenomena relating to the "Enemy Controller" scenes from the Virtual Arc was referenced in a minigame on the Duel Terminal Arcade game. (See: http://www.youtube.com/watch?v=CLudBLSx9LQ)
* AssholeVictim: Bandit Keith, but especially Marik's father. [[spoiler:Weevil in the "Waking the Dragons" arc.]]
* AstonishinglyAppropriateAppearance: Goes from mild (Rex Raptor and Weevil Underwood have dinosaur and insect themed decks, respectively) to the truly tasteless ([[FanNickname Zombie boy]] has an all zombie deck).
* AttemptedRape: Anzu is lured into a gym hall where a creep with a camera is waiting. Luckily, Yugi arrives on time. In the dub, the camera (and shots of Anzu's thighs) were edited out.
* AwesomeButImpractical: Pretty much every character's deck only works because of TheMagicPokerEquation and that fact that the writers can let them get whatever cards they need. For a fun drinking game, watch the show and take a drink any time a duelist's strategy could be utterly ruined with any simple one-for-one destruction card like Mystical Space Typhoon or Smashing Ground -- cards that no one seems to use, not in multiple copies at least.
** Rare cards in-universe are ''[[ExactlyWhatItSaysOnTheTin Rare Cards]]''[[note]]the prints possibly only numbering around the double digits world wide[[/note]], which most of those destruction cards are (ex. Harpie's Feather Duster).
** This continues into the spin-offs as well. Most of the protagonists of ''GX'' rely on Fusion monsters, which are horrible for hand advantage and are easily disposed of with any of the mentioned destruction cards. There's a reason real-life [=VWXYZ=] and [=Cyber End Dragon=] decks don't exist in any seriously competitive capacity, and the Elemental Hero ones rely on cards from the manga -- they just don't work like the anime shows them.
* AVillainNamedZrg: Zorc.
* AxCrazy:
** Yami Marik and Yami Bakura.
** Even our hero Yami Yugi can become AxCrazy [[RoaringRampageOfRevenge if you push the right buttons.]]
* BadassAdorable: Yugi.
* BadassNormal: Yugi -- the normal one, not the Pharaoh one -- manages to take out all three God Cards in one turn against Atem.
** Jonouchi as well who's the most normal of the main duelists.
* BeamOfEnlightenment: Any time one of the characters has a sudden revelation. Mostly when Yami figures out how to beat his opponents. It happens when Yugi collapses during his second duel with Pegasus. Yugi's friends can sense it, despite his isolation in the Shadow Realm.
* TheBechdelTest: Despite having only one female character stay from the beginning to the end of the story, and having a maximum of 4 important female characters ever in the same scene (or season), it actually passes. But not by much.
* BeethovenWasAnAlienSpy: Capsule Monsters only- Alexander the Great had the Millennium Ring.
* BerserkButton: If you don't want to see a very angry Kaiba, [[http://www.youtube.com/watch?v=BMt54zFXzpI#t=6m32s don't tell him Yugi lost a duel]].
** Or when you try to steal his company. Or you kidnap his brother. The guy just has anger issues coupled with the fact that everyone takes cheap shots at him.
** And if you don't want to anger Jou, don't insult him in any way or harm any of his friends.
*** You want BerserkButton? Try [[http://www.youtube.com/watch?v=uYx_sJRmgeY what Yami did to Insector Haga]]. Never ''ever'' threaten Yugi in his Other Self's presence. Just... don't.
* BetweenMyLegs: This shot is how Rebecca is introduced in her first appearance.
* BewareTheNiceOnes: Ryou Bakura is a very sweet, shy, quiet, polite guy. With a SuperpoweredEvilSide that he's only vaguely aware exists.
** Yugi later on in the series has also shown that he has the ability to kick ass even ''without'' his Other Personality, at times.
*** Also, the Seal of Orichalcos.
* BigBad: Kaiba, Pegasus, The Big Five, Noah/Gozaburo, Marik, Dartz, and Zorc/Bakura. Subject to the SortingAlgorithmOfEvil.
* BigDamnHeroes: Seems to happen a lot. Notable because oftentimes the mere presence of the friends of whoever is dueling gives them the strength to win, or at least continue playing into the next episode.
* BigShutUp: Pegasus tells Dark Bakura to shut up after the latter reads his past like an open book through Duel Monster cards used as Tarot cards.
* BilingualBonus: Played straight with the Egyptian text. Atem's name is written as "Atemu" and the carvings on Rishid's face and Malik's back are genuine hieroglyphs. The author [[DidDoTheResearch knew what he was doing]].
** Subverted in the anime, where the Enochian text on the Orichalcos cards is a random jumble of nonsense. However, the card title spells "Orichalcon" and the rim of the seal spells "Oreichalcos" twice.
* {{Bishonen}}: Marik Ishtar. Ryou Bakura. Ryuji Otogi. The latter two even have their own in-universe fan clubs.
* BitchInSheepsClothing:
** The spirit of the Millennium Ring, even more so in the manga. In the anime, he has been an antagonist from the beginning, trying to kill the gang in a duel, attempting to kidnap Mokuba because he needed a soulless body, and everything else that happened. In the manga however, he doesn't show any ambitions to kidnap Mokuba, he just helps Honda, making him wonder whether the spirit was now on their side. Sure, Yugi and the others were still a bit wary of him, but by the time the whole Dungeon Dice Monsters/Putting the puzzle together in the fire scenario was going down, they seemed to almost consider him a (not so trust-worthy, admittedly) part of the gang.
** Slightly different in the anime, but maybe a more literal example, as he used the innocent Bakura as his "sheeps clothing". One could almost never be sure who was in control, one second had Bakura smiling innocently, the next second when the others turned their backs, the spirit smirked.
** Marik. When he personally meets up with Yugi's friends for the first time, he pretends to just having found Bakura injured. He actually does this to gain their trust. He introduces himself to them as "Namu", acting as a humble beginner who participates in Battle City Tournament. Right afterwards Marik's minions attack and Anzu and Jounouchi get kidnapped, then brainwashed. He keeps up the innocent act later too, claiming to having gotten into finals only because of dumb luck, even as Jounouchi grows suspicious of him. Now, Marik's past and his dark side business considered, he still showed rather [[ManipulativeBastard malicious personality]] on his own. He didn't seem to have any regrets of his actions either, except for getting Rishid hospitalized and over the fact that he had blamed pharaoh for the death of his father. Rather, he's just confused why would Yugi want to help him after he tried to kill them all. So it might be that he's still Bitch in sheep's clothing when we see him again later in the series, just maybe not to the same extent as before.
* BlackBox: The IC chips inside the cards have been described as this in the Pyramid of Light novelization.
* BlackCloak: Marik Ishtar and the other Rare Hunters are garbed like this when we are first introduced to them.
** Also in the Waking the Dragons arc.
* BlackMagicianGirl: TropeNamer due to the "Dark Magician Girl" card, which is actually named "Black Magician Girl" in the original anime.
* BlindIdiotTranslation: The card known in Japanese as "Shisha Sosei" (literally "Raise Dead") was called "Reborn the Monster" early in the English dub, before changing to "Monster Reborn", which makes a lot more sense.
* BodySurf: Marik causes much grief to the protagonists by doing this during the Battle City arc.
* BookEnds: For Yami Bakura's involvement in the overall story, anyways. Both the first and last games the Pharaoh plays against him are [=RPGs=] with the souls of his friends at risk. Although in the anime, their first game was changed to Duel Monster with a role-playing aspect, if you could call it that.
** For a straighter example, Yugi's winning card in the last duel of the series is Golden Sarcophagus; it's [[LampshadeHanging pointed out]] that the card looks just like the box the Millennium Puzzle was in, [[spoiler:[[InvokedTrope and that the box that brought Yugi and the pharaoh together would be the very thing to bring them apart.]]]]
* BoringInvincibleHero: See FailureIsTheOnlyOption, below.
* [[{{Bowdlerise}} Bowdlerization]]: Of the manga: skipping approximately the first seven volumes of Dark Yugi challenging bullies/criminals to Shadow Games and inflicting Penalty Games (a flashback replaces Dark Yugi's infamous "One Finger Battle" game with "[[MerchandiseDriven Draw the strongest Duel Monsters card]]"), disregarding Kaiba's death-themed amusement park, changing the few of Dark Yugi's Penalty Games that they're willing to show into kid-friendly "Mind Crushes," etc. -- among other things. Duelist Kingdom, DDD, and Millennium World gets most of this treatment, while Battle City gets less of it (most of it comes from Dark Marik). All prime cases of the anime being made LighterAndSofter compared to the manga in order to [[MerchandiseDriven appeal]] to an [[MisAimedFandom audience]] on TV.
** The English dubbed anime is this to the above, which makes the situation all the more funnier.
* BrainwashedAndCrazy: Happens quite a bit considering most of the enemies tend to use this trope. Jonouchi and Bandit Keith would be two of the most notable cases -- in both cases by Marik.
* BreakoutCharacter: The Dark Magician Girl, being the MsFanservice of the franchise, is far more popular than any other duel monster from the original series save for the iconic Blue-Eyes and Dark Magician. She's even playable in some of the video games.
* BreakTheHaughty: Kaiba gets this a lot.
** Cheap shots. If they took him on head-to-head, no dice.
* BreatherEpisode: A breather arc, actually. The relatively laid back KC Grand Prix story fits right in between the much more intense Doma and Millennium World storylines.
** The anime version of the Dungeon Dice Monsters story serves as this as well (in the manga... not so much).
* BrokenBird: Mai Valentine/Kujaku.
* BrokenBridge: The only thing that keeps Marik from interfering the events of [[StealthPun Noah's Arc]] is... a locked door.
** Although, he did manage to blow up Noah's control system.
* BroodingBoyGentleGirl: Priest Seto and Kisara in Ancient Egypt, Yami Yugi and Tea in the main timeline
* ButNowIMustGo: [[spoiler: Atem.]]
* ButThouMust: The Playstation game ''Yu-Gi-Oh! Forbidden Memories'' does this often.
** The Sacred Cards does this when you finally collect all three god cards, making it impossible to ever use the third card.
* ButtMonkey: Jou at times, usually at the hands of Kaiba. Bakura is even more so the Butt Monkey. That might be hard to realize considering that when most people think of Bakura they think of the Dark Spirit that possesses him starting in the first season, but the very fact that he spends little time in control of his own body shows just what a Butt Monkey he really is. When he rarely does come to his senses, he has no idea what's going on, and sometimes must cope with the consequences of the spirit's actions.
** Remember that when Joey picks a fight with Kaiba, he usually loses, so it's his own damn fault.
* CallingYourAttacks: "DARK MAGICIAN, '''DARK MAGIC ATTACK'''!" "BLUE EYES, COUNTER WITH '''WHITE LIGHTNING'''!" and so on ad infinitum. Several of these attacks even have their own cards, which require their monster to be out. Mainly used for important monsters early on, with smaller ones just getting descriptions of what was happening, but later in the series and on through GX and 5D's it reaches silliness of epic proportions.
** Yami Yugi seemed to use "OBLITERATE" often, for both Exodia and Blue-Eyes.
** Though, characters will tell the one calling the attacks to shut it. Episode 120 was a good one, even if Kaiba (who told Gozaburo to be quiet) told us what the card did anyway. The "I know what the card does, you fool" was just marvelous.
* CalvinBall: Duel Monsters seem to be this in Duelist Kingdom, since rules that would be nonexistent happen frequently, such as Kazejin blowing away an attack yet it still affecting the other monsters, Normal Monsters having effects, and Yugi activating a non-Quick-Play Spell from his hand during an opponent's turn.
* CardGames: Duel Monsters, obviously. And as the title suggests, it gets a bigger promotion than it did in the manga.
* CCGImportanceDissonance: Countless examples, the most famous of which being the Dark Magician, Blue-Eyes White Dragon and Red-Eyes Black Dragon.
** Those cards did have importance in the early days of the card game, since effect monsters and monster removal, amongst other meta-defining concepts, were few and far between at the time, thus making the game more about which monsters had the higher stats, with BEWD in particular standing alone at the top.
** Even now, most monsters with 3000 or more ATK have some form of summoning conditions to keep Blue-Eyes White Dragon unique (although these conditions often make such monsters easier to summon).
* ChainedByFashion: Exodia.
* CharacterDevelopment: Mostly for the two Yugis, but everyone gets a decent amount at the least.
* CharlesAtlasSuperpower: Kaiba can throw cards at someone with such force it hurts like they're throwing stars, Yami Yugi (manga only) can break a dice in two with his Millennium puzzle, Jonouchi can break down a wall, etc. Each of whom have almost no visible muscle.
* ChastityCouple: Mai and Jounouchi/Joey. Also Yugi and Anzu/Tea, though the latter has a crush on the former's [[SuperpoweredEvilSide superpowered evil side]].
* ChekhovsGun: Although the fact that we rarely see the characters' entire decks allows players to bring out a previously unseen card to turn the game around, pay close attention when a character specifically singles out or is shown acquiring a new card before a duel. It's bound to be important in the upcoming match.
** Played straight in the Duelist Kingdom Arc, where Joey is seen trading for Sword and Shield, which he later uses against Ghost/Bonz ([[FanNickname Zombie boy]]) to pull off a win. At the same time he got Kunai Whipchain and Salamandra, which he used to defeat two troublesome monsters in the team duel with the Paradox Brothers, as well as Baby Dragon, which combined with the Time Wizard given to him by Yugi ended up finishing off Mai in his first duel with her.
** Kuriboh made a blink-and-you'll-miss-it appearance in episode 5 to diffuse one of Weevil's traps, before Yugi brought it back in episode 24 to hold off Kaiba's Blue-Eyes Ultimate Dragon.
** Another, ultra-delayed Chekhov's Gun comes from the first title sequence, where Yugi's shadow splits in two, representing his two sides. 220 episodes later, this happens when Yami and Yugi face each other in the ceremonial battle.
** If the camera ever pays particular attention to the cards that players put in the graveyard when they have to discard cards for some reason, it's likely (though not guaranteed) that at least one of those will have an effect that works in the graveyard, or that the player will otherwise get to use that card later on.
* CherryTapping: Yugi managed to stall off Kaiba's Blue-Eyes Ultimate Dragon with Kuriboh, labeled as the weakest monster in the game.
** Yugi seems to have a thing for using weak monsters to deliver a disproportionate bitch slap to his opponent.
*** Whenever he played Capsule Monsters, the game was rigged so that Yugi's monsters were all weaker than his opponent's, yet he destroyed them anyway.
* TheChewToy: Joey, to Kaiba.
* ChronicHeroSyndrome: Yugi
* CircleOfFriendship
* ClipShow: Episode 74, "The Rescue"
* ClosedCircle: In the Virtual World arc.
** Also in the Dawn of the Duel arc.
* CloudCuckoolander: Jounouchi/Joey.
* CockFight: Tristan and Duke, over Serenity.
* CollectibleCardGame
* CookingDuel: Figuratively speaking. The series often stakes the lives of its characters, or even the fate of the world, on a game of Duel Monsters.
* CoolBigSis: Mai Kujaku.
* [[CosmicChessGame Cosmic Role-Playing Game]]: Season 5
* TheCorruption: Multiple instances with various characters. The entire Doma arc works on this.
* TheCracker: In an early episode, Seto Kaiba goes through a Batman-esque security system to reach a sentient computer, which he uses to hack into Pegasus's computer system to [[MundaneUtility mess with a duel]]. [[LampshadeHanging Lampshaded]], of course, in TheAbridgedSeries.
* CrazyConsumption: Yami Bakura and his steak. Censored in the dub.
* CurbStompBattle: The first Kaiba vs. Joey duel.
** Zigfried VS Weevil and Rex. At the same time. ''In one move.''
** Also the first Yami/Kaiba VS Rare Hunters battle. Kaiba summoned Lord of Dragons AND special-summoned all three Blue Eyes and a spare dragon in just the first move, then summoned Obelisk on Round Two (sacrificing ''his Blue-Eyes to do so'') AND sacrificed his other remaining monsters to activate Obelisk's TotalPartyKill special ability to defeat both opposing players (the Pharaoh, for what it's worth, only had enough time to play Kuriboh while all of this was going on except Kaiba wanted to flaunt power).
** The Winged Dragon of Ra versus basically anything. Except for Mai's CriticalFailure attempt at using it.
** The first Kaiba/Pegasus battle became one as soon as Toon World was played. Later Kaiba smartened up.
** Nameless PlayerMooks versus numerous {{Designated Villain}}s like Rex and Weevil.
** Valon defeats Rebecca and Duke on his second turn.
* CutAndPasteTranslation: Most infamously the [[NeverSayDie Shadow Realm]] concept.
* CutesyDwarf: Yugi.
* TheDarkSide: Many characters in Yu-Gi-Oh! fall into some Dark Side's trap, usually by trying to use an ArtifactOfDoom (e.g., Marik, Bakura, Pegasus, Aknadin). Yami Yugi is not immune to this effect.
* DeadManWriting: Subverted with Pegasus in the Doma filler saga. [[spoiler: He wasn't dead, merely comatose due to his soul being removed.]] However, one could bring up the manga here...
* DeadpanSnarker: Later in the 4Kids dub, [[http://www.youtube.com/watch?v=vrsdzQ1E0c0 Bakura is quite good]] [[http://www.youtube.com/watch?v=awv8pPgA7Qo at this.]]
** Kaiba is another.
-->Gozaburo: "I treated you better than my own son!"
-->Seto: "Thanks for nothing."
** And again:
--->Seto: "Anyone who's late to my tournament will automatically be disqualified. Mokuba, make sure Wheeler's late."
** From the Waking The Dragons arc:
-->'''Kaiba:''' So you have a geek army. Is that supposed to scare me?\\
'''Dartz:''' Only if destroying an innocent soul concerns you.\\
'''Kaiba:''' Nah. As the president of a major company, I have to do that every day.
* DeathByChildbirth: Marik's mother.
* DebtDetester: Kaiba claims that Tea helping Mokuba escape from the Rare Hunters is the only reason he's helping Yugi find his friends. Then he uses it as his reason for saving Tea's life. Considering all the times he makes a point of explaining how he's only "helping" the gang out of selfish reasons, it's pretty clear that it's only a shield for his HiddenHeartOfGold.
* DefeatMeansFriendship: Ryuji Otogi/Duke Devlin in the ''Dungeon Dice Monsters'' arc. To an extent, Mokuba Kaiba and Marik Ishtar later on.
* DefrostingIceQueen: Mai Kujaku/Valentine for the first few arcs, and then heads back to Arctic levels during most of Season 4 due to her FaceHeelTurn.
** Kaiba is a male example, at least in the Japanese version. He becomes more amiable and less openly insulting towards the others.
* DemotedToExtra: Ryou Bakura in the second anime. In the manga, he appears with the main group most of the time after his initial appearance and has tons of screentime, while in the anime, he usually only appears whenever it involves Yami Bakura or if it's Yami Bakura ''pretending'' to be the real Bakura (in most cases). Lampshaded in [[WebVideo/YuGiOhTheAbridgedSeries The Abridged Series]]. Who's Bakura?
** Bobasa as well, as his major role in the Millennium World arc from the manga was instead given to Shadi while he was mainly reduced to comic relief for the few episodes he appeared in, until his final appearance where he takes Yugi and the others to the Pharaoh's temple. [[spoiler: In fact, in the manga, Bobasa ''is'' an alternate identity of Shadi/Hassan.]]
* DependingOnTheArtist: The first two seasons of the second series anime follow Kazuki Takahashi's manga style pretty well, but the various animators start to show their specific styles around the end of the Battle City finals and into [[OvertookTheManga non-manga material]]. This causes discrepancies between the proportions of the characters; for example, the ever-changing size of Yugi's hair. Some artists, like Kagami Takahiro, are consistent with art and animation. Others, like Kawaguchi Keiichirou, are very OffModel.
* DesignatedVictim[=/=]DistressBall: Hiroto Honda/Tristan Taylor falls here too.
** To be fair, many of Yugi's rivals fall into this trope.
* DeterminedExpression: A staple of Kaiba, to the point where many a fanfic has waxed eloquent over his "icy death glare". Yami Yugi usually prefers speech-making, but has been known to utilize this effectively as well. Joey doesn't do this as frequently as Kaiba, but when he does, a crowning moment of awesome ''will'' ensue.
* DetonationMoon: Yugi has Giant Soldier of Stone destroy his own Full Moon card. It recedes the ocean from the field, beaching Mako/Kajiki's monsters. Years later it would be ascended into [[http://yugioh.wikia.com/wiki/Attack_the_Moon! its own card.]]
* DeusExMachina: Whenever one of the heroes is in a hopeless situation, the solution is often them drawing a card we've never seen or heard of (and in many case never will again) that provides the perfect solution. Also known as "believe in the heart of the cards".
* DeusExitMachina: The three Egyptian God Cards, which Yugi worked hard to acquire in Seasons 2 and 3, are stolen in the very first episode of Season 4 by the local QuirkyMinibossSquad and are drained of their power. Yugi manages to regain them in time for the final battle, but up until then only one God is used, just once right after the theft, and then by a friggin' {{Mook}}, who should have been unworthy of/too weak to use it, but gets to anyway because he has a power that allows him to have limited control over it.
* DidDoTheResearch: Though occasionally the exact details are fuddled, the mythological concepts explored throughout the franchise show that someone obviously did their homework.
* DidYouThinkICantFeel
* DoNotAdjustYourSet: Kaiba uses this to announce the Battle City Tournament.
* DubInducedPlotHole: In Season 2 Isis/Ishizu arrives in Domino City via plane. A Domino museum official welcomes her "to America." This is contradicted in Season 4 when the protagonists actually travel overseas to America to investigate the local {{Filler Villain}}s.
** In the dub, they are are said to be flying to ''California''. It is perfectly reasonable for people living near the East Coast to need to take a plane to California.
* DubNameChange: The dub was done by FourKidsEntertainment, after all. Some card names were also changed, for example, Black Magician being renamed to Dark Magician (and the same for the card's female counterpart, Black Magician Girl to Dark Magician Girl) and its corresponding attack card, Black Magic, being renamed to Dark Magic Attack.
* DudeWheresMyRespect: Joey says this almost word for word upon hearing that Kaiba refused to invite him into the Battle City tournament even though he was the runner up in Duelist Kingdom.
** {{Lampshaded}} in Duel Academy's school pledge.
* DuelsDecideEverything: Apparently even with Pre-YamiYugi Duel Monsters games decided a few inane things, but post-Season 2 pretty much every Duel could be a Shadow Game or a Dangerous Bet.
* DysfunctionJunction: Several characters experienced a tragic and/or depressing event in their life, especially the villains.
* EarlyInstallmentWeirdness: Duelist Kingdom used completely different rules (if there even ''were'' any, with the series often functioning with NewRulesAsThePlotDemands) than later arcs, playing more like an RPG than a trading card game. There are too many to list, but examples include Yugi being able to "beach" Mako's sea creatures, being able to target separate ''parts'' of monsters, attacks being able to "miss," etc.
** Later seasons brought the rules in closer with the real-life card game. Before Duelist Kingdom, the source material [[Manga/YuGiOh manga]] wasn't completely about Duel Monsters, and the entire manga was much darker; for example, IronicHell as the consequence for whoever lost Dark Yugi's Shadow Games or any of the villains.
** Even the cards are this. In this series the cards are mostly inclined towards the horror genre, religion and mythology, especially but not restricted to Ancient Egypt. Later series since ''GX'' have a "futuristic and dragons theme" for the cards and never looked back since.
* {{Earworm}}: The Japanese openings and endings. The biggest offender is Rakuen from season 3.
** Shuffle and Overlap count as big offenders too - the former's very catchy and the latter is just damn awesome.
* EasilyForgiven: The Kaiba brothers, Pegasus, Malik.
* EmbarrassingRescue
* EnvironmentalSymbolism: Whenever Shadi [[JourneyToTheCenterOfTheMind goes into someone's Soul Room]] with his Millennium Key, which reflects their personality and mental state.
* EvilIsNotAToy: Nor is it a card game, ''Pegasus''.
* EvilSoundsDeep: Played straight with Yugi/Yami Yugi and Marik/Yami Marik. Both played straight and subverted by Bakura/Yami Bakura in the original Japanese. Yami Bakura does have a deeper voice than Bakura, but both have a [[LarynxDissonance high-pitched squeaky effeminate voice]].
** Also used with Marik when his SuperpoweredEvilSide isn't in control. When he's pretending to be a protagonist, and after his HeelFaceTurn, his voice is higher and softer.
** Also inverted with Noah; when he's a villain, his voice is high-pitched and bratty, but when he makes his HeelFaceTurn, it gets lower and more mature.
** Played straight with Yugi in the first series anime produced by Toei.
* EvilVersusEvil: The duel between Yami Marik and Yami Bakura is this.
* ExactlyWhatItSaysOnTheTin: A lot of the cards, like "Red-Eyes Black Dragon," "Man-Eating Treasure Chest" and "Dark Magician," just to name a few.
** Ladies and gentlemen, feast your eyes upon the [[http://yugioh.wikia.com/wiki/Giant_Turtle_Who_Feeds_on_Flames Giant Turtle Who Feeds On Flames]]!
* ExtraEyes: Pegasus' Thousand-Eyes Restrict.
* FaceFramedInShadow: Every major villain has this going on for them, especially friends who have been made BrainwashedAndCrazy.
** Also used to somewhat hide Yami Yugi's identity, first in Season 0 when Tea wonders who saved her and again in Season 2 for Kaiba during Ishizu's Millennium Necklace visions. The shadow even followed him as he stood up.
* FailureIsTheOnlyOption: Even though they're playing a card game, of which the consequence of losing would normally only be a hit to the loser's ego (if that), the main characters are frequently involved in "shadow duels" where the gist is losing = death, making FailureIsTheOnlyOption (for the villains)/BoringInvincibleHero played straight. This applies to all Yu-Gi-Oh anime, not just this one.
* FairytaleWeddingDress: In a fantasy sequence in the first anime.
* {{Fiction 500}}: Seto Kaiba.
* FetalPositionRebirth: Yami Yugi at the end of the Orichalcos Arc.
* FieldPowerEffect: Various boosting and nerfing cards, as well as terrain.
* FightingSeries: Using a card game.
* FillerArc: Virtual World, DOMA, and Kaibacorp Grand Prix.
** Kaiba hilariously lampshades this directly after the Virtual World Arc, directly after they've all narrowly escaped with their lives.
--> Kaiba: Alright, that little detour was a complete waste of my time and effort. So let's move on and pretend that nonsense never happened. It's time for us to continue the Battle City Finals! Set us back on course, to Kaiba Corp Island.
* FillerVillain: Dartz, Noah, Gozaburo, and Zigfried von Schroeder.
* FiveBadBand: The Big Five, Dartz and his men. You could also make a case for Pegasus and his Player Killers if you wanted.
* FiveManBand
** TheHero - Yami Yugi/Yugi
** TheLancer - Jounouchi (Joey)
** TheBigGuy - Honda (Tristan)
** TheSmartGuy - Yugi/Kaiba when he's not being a {{Jerkass}}/ Rebecca in Season 4 and 5
** TheChick - Anzu (Tea)
** TheSixthRanger - Bakura in the first season (being demoted from a main role and SmartGuy status he had in the manga), Ryuji Otogi (Duke) in later seasons.
* {{Flanderization}}: Kaiba's rude tendencies in the dub. Compare:
--> dub!Kaiba: "Mokuba, make sure Wheeler is late."
--> Japanese!Kaiba: "Mokuba, please show them around."
--> dub!Kaiba: "Wait and see, you geeks haven't seen the last of me." (Paraphrasing.)
--> Japanese!Kaiba: "One day, I will invite you [to Kaiba Land]."
** Bakura, (lampshaded in the Abridged Series too):
--> Marik: "My name is Marik"
--> Japanese!Bakura: "I'm Bakura."
--> dub!Bakura: "I don't care."
* FreudianExcuse: [[spoiler:The whole reason Thief King Bakura tries to take over the world in the first place is because he saw the Kul Elna massacre first-hand and was its only survivor.]]
** [[spoiler: And yet, the Bakura who wanted to rule the world actually wasn't Thief King Bakura, but instead Zorc taking over Bakura's body. Nothing makes sense.]]
** Also Seto, arguably, given his orphaned childhood and [[AbusiveParents history with Gozaburo]].
* FriendlessBackground: Yugi had one of these before finishing the puzzle.
* FriendshipMoment: Given the [[ThePowerOfFriendship main theme]] [[TrueCompanions of the series]], there's bound to be plenty of this.
** A really touching one in particular is between Yami and Yugi. After Yugi is discharged from the hospital after his duel with Bandit Keith, he becomes uncharacteristically quiet and gloomy. Even though he knows something is troubling him, Yami decides to patiently wait for Yugi to voice his concerns, and only then he realizes that Yugi had been afraid of losing him after his duel with Keith, and made him realize that Yami might have to leave someday. So Yami, knowing full well that he would have to leave his side in the future, tells him that despite what he ''had'' to do, he ''wanted'' to be with him forever. And Yugi, realizing that even though Yami would really have to leave, replies that he also wished for them to be together, and that even if the Pharaoh didn't get his memory back, he and Yugi would make new memories together.
* FunSize: Yugi Mutoh and Yami.
* GeoEffects: Field Power Bonus. Emphasized very much earlier in the card game, but dies out to only Field Spell Cards by the Duelist Kingdom finals.
* GenkiGirl: Mana, whose introduction consisted of jumping out of a vase to glomp the pharaoh.
* GetAHoldOfYourselfMan: Yami gets one of these from Joey in the form of a punch to the face.
* GirlsLoveStuffedAnimals: Rebecca had a teddy bear that she regularly spoke to in her first appearance. By the time she reappears in the Doma arc however, she's ditched the [[TastesLikeDiabetes "cutesy little girl"]] angle, and Teddy is nowhere to be seen.
* GottaCatchEmAll: Averted -- even though the show is largely about a collectible card game, the actual ''collection'' aspect is barely seen, with most characters pulling new cards out of nowhere during duels rather than explicitly obtaining them through booster packs or trades.
** Yugi's grandpa owns a trading card/game shop and Kaiba is rich. The second season has the rule that a loser must hand over their rarest card after they lose, with Joey's (formerly Rex Raptor's) Red Eyes Black Dragon being a significant plot point. Joey often uses cards he received from winning, such as Jinzo.
*** Possibly an Aversion of a Subversion (maybe?). Unlike in real life, where serious players usually have 2 or more decks at once for a CollectableCardGame, all the characters in ''Franchise/YuGiOh'' have only 1 deck that they retool constantly. That being said, those retoolings might as well count as entirely separate decks unto themselves.
*** Mai Kujaku, who switches from Harpies to Amazons from Duelist Kingdom to Battle City, is probably the closest-to-real-life player in that she has an ''entirely'' new deck, though she still includes her Harpies. Then again, can you blame Kaiba for wanting Blue-Eyes in every deck?
*** The Pharaoh does, at one point, buy a booster pack which contains a card seen in later duels. While on a date with Anzu. Who notes grimly that it's the happiest he'd been thus far.
** Played straight on the part of the evil version of Bakura, who wants to collect all the Millennium Items so he can rule the world.
*** Depends on which version of Bakura from which version of the anime (or manga) you ask, though collecting them all is still featured prominently either way. Also in Season 0 when he would collect the souls of his victims into miniatures.
** In Season 0, Yugi's Grandpa said that Capsule Monsters was not a collection game, but the epitome of a fighting game. Yami Yugi later echoed this in delivering his LaserGuidedKarma.
** Yugi when it comes to games in general - he has every kind of game imaginable in his room. He even went as far as going to a rival gaming shop ([[FamilyBusiness which his grandfather was highly against]]) just so he could get his hands on the newest game they were marketing (Dungeon Dice Monsters).
* GracefulLoser: Pegasus, who after being thoroughly trounced by Yami, fulfills his promise by releasing the souls trapped in cards and stops causing problems for the protagonists.
** Averted with Kaiba though.
* GradeSchoolCEO: Seto Kaiba won Kaiba Corp from his step-dad when he was a teenager, and turned it from a weapons-manufacturer to a gaming company.
* GrandTheftMe: Gets attempted MANY times. Usually tends to fail, but succeeds on rare occasions.
* GratuitousEnglish: Pegasus in the Japanese anime.
** "''UNBELIEVABLE!'' Kore wa NIGHTMARE! Bad dream!"
** Most of the cards have names in GratuitousEnglish too; Red-Eyes Black Dragon and Blue-Eyes White Dragon are completely unchanged from the Japanese version.
** Also in the Japanese anime, terms like "duel(ist)", "player", "direct attack", "Duel Disk", "deck", "card", "Monster/Magic/Trap Card", "turn", "draw" and the different phases of the duel (i.e. Draw Phase, Standby Phase, Main Phase 1, Battle Phase, Main Phase 2 and End Phase) are said in English. "Reverse card, open!" is another commonly-heard English phrase in the Japanese anime.
** Rebecca also speaks a lot of English. Her very first line in the series is "Hello, my name is Rebecca." Both Pegasus and Rebecca are American, so it stands to reason that they would speak English. However, Bandit Keith, who is also American, doesn't speak one word of English, strangely enough.
** The Egyptian God Cards have the names written on them in English in the Japanese version of the anime (being the only cards that do). The names written on them are completely different from what they're called in both Japanese and English - THE SUN OF GOD DRAGON (Ra no Yokushinryū/The Winged Dragon of Ra), THE GOD OF OBELISK (Obelisk no Kyoshinhei/Obelisk the Tormentor) and SAINT DRAGON - THE GOD OF OSIRIS (Osiris no Tenkūryū/Slifer the Sky Dragon).
* HackedByAPirate: Pegasus does this by showing his favorite cartoon rabbit character when he counter-hacks Kaiba trying to hack into his system.
* HackerCave: Owned by Seto Kaiba.
* HamToHamCombat: Although many duels feel this way, the Yugi vs. Kaiba ones are the greatest examples. At some points it feels like their voice actors are competing to see who can do the most over the top performance and still keep it in the final cut.
** The Yami Marik vs. Yami Bakura duel is a fabulous example of this, especially since most of their dialogue consists of them making very enthusiastic death threats to each other.
* HannibalLecture: During every single duel against a major rival.
* HardWorkHardlyWorks: Yugi plays it straight, Joey/Jounouchi actually earns his wings through hard work.
** We're talking about a ''card game'' here. Two years practice tops is all anybody needs to be good at it...
*** Along with several thousand dollars spent on building a deck.
*** And yet the two finalists in Duelist Kingdom were still in high-school, one of whom had to work just to pay for his own school. Although, he won pretty much of his duels in that arc using either Time Wizard (gift from Yugi) or Red-Eyes B. Dragon (won from Rex using Time Wizard). After that, he always wins using either a rare card he won or just luck.
** Yugi has always been extremely talented at games.
* HealthcareMotivation: The reason Jounouchi participates in the Duelist Kingdom tournament.
* [[HeartIsAnAwesomePower Heart of the Cards is an Awesome Power]]: Because in a GamingAndSportsAnimeAndManga, being able to choose what cards you draw in a duel means everything.
* HeelFaceTurn: Malik, and in the anime, Pegasus.
* HeroesPreferMotorcycles: Tristan/Honda rides a motorcycle.
* HeroicWillpower: Jonouchi when controlled by Marik.
* HeroicSafeMode: Yami to Yugi.
* HeterosexualLifePartners: Yugi and Yami Yugi, Joey and Tristan.
** Yugi and Joey are like this as well, with Yugi calling Joey his best friend. It gets to the point that, [[spoiler:when Joey is brainwashed and they're forced to duel]], Yugi does his best to help Joey and, when Yugi thinks he's about to die, he tells Joey that he loves him.
* HollywoodHacking: Complete with virtual doors that can be blown up with virtual dynamite...
* {{Homage}}: The card game was originally intended as a homage to ''MagicTheGathering'', of which Takahashi is a fan.
* HostageForMcGuffin: So much so (especially with Kaiba's little brother Mokuba) that [[http://www.dailymotion.com/littlekuriboh/ LittleKuriboh]]'s GagDub of the show has an entire running gag built around it.
* HotForTeacher: Subject to interpretation, but Mana in the anime is ''very'' devoted to Mahad. Her goal through season five is to become a better magician, both because it's his will for her and because she wants to be able to summon and see his spirit. "Prince can summon him from the tablet, right? Please! Bring me and Master together!" She talks or thinks about him in every scene, and her other goal is to always be with and protect him... which she succeeded in, if the existence of the Black Magician Girl in modern times is any indication. One must note that the subtext is only present in the Japanese version -- 4Kids rewrote her dialogue and character entirely until she and Mahad have nothing but a classroom relationship.
* HotBlooded: Jounouchi/Joey.
** Bakura, especially as Thief King Bakura in season five. He makes the most arrogant pronoun ever (Ore-sama) sound good in constant use, and... 'ORE-SAMA NO TURN!'
*** Sort of lampshaded in the Japanese anime. In a duel between Yami Bakura and Yami Malik, Bakura shouts "Ore-sama no turn!" to which Malik replies "You're no ore-sama."
* HybridOverkillAvoidance: Usually averted, but played straight in the first tournament when Yugi fused his Mammoth Graveyard to Kaiba's Blue Eyes Ultimate Dragon to slowly weaken it.
* IAmYourOpponent: Used a few times by Yugi.
* INeverSaidItWasPoison: You could practically make a drinking game out of the number of times this basic scenario shows up: Yugi activates a card effect. Opponent believes it to be targeting their best monster and make moves to protect it, scoffing Yugi's "wasted effort." Yugi then reveals he was going after something else instead. Opponent has a massive OhCrap moment and, usually, loses shortly thereafter.
* IdiotBall: In the first ever duel between Joey and Kaiba, Joey's entire strategy could be summed up as "summon monster to attack." He apparently forgot that his monsters weren't nearly strong enough to beat Kaiba's, but he just kept summoning them and having them attack Kaiba's monsters, so they'd be destroyed instantly and cost him points. He never shows this level of stupidity in any duel before or after this. Justified as he was unfamiliar with the Duel Disk technology and didn't know how to set monsters in defense mode.
** Yugi's largest IdiotBall was when, in his duel against Pegasus, he summoned Celtic Guardian to attack Toon Mermaid, hoping to destroy them both. If Toon Mermaid merely dodged the attack, as Toon Blue-Eyes had done before, Pegasus would attack Celtic Guardian with Toon Summoned Skull, winning the duel. But then, Yugi was under a considerable amount of stress.
** Here's a drinking game--watch the series and take a drink every time a duelist makes a move and doesn't notice the opponent has countered it until its too late. Blame RuleOfDrama, since apparently if it'll make for a dramatic twist then duelists can activate cards without announcing such (ie, Isis activating Blast Held By A Tribute to "secret" infect Obelisk without saying so). However, in the real card game every play of a card must be announced and your opponent given a chance to respond if they are able, and if they choose not to they don't get to just rewind and change their minds once you begin to make another move.
** From the Waking The Dragons arc, Yami playing the Seal of Orichalcos that Raphael gave him in order to avoid losing the duel. There was literally nothing at stake until he played that card, since the "loser loses their soul" condition of the duels in this arc only applies ''after'' the Seal has been played. He could have just taken the loss and walked away to continue his fight against Dartz's organization, but no, he just ''had'' to win. Of course, this may well have been the "evil" that Raphael said was in him in the first place.
* IfIHadANickel:
-->'''Seto''': If I had a dime for every time you said the word destiny, I'd be even richer.
* IHaveYourWife: Used by various villains throughout the series. The target is usually Mokuba, who is kidnapped a grand total of 15 times.
* IJustWantToHaveFriends: When Yugi first completes the puzzle, he makes a wish on it to have some true friends.
* IKnowYoureInThereSomewhereFight: Yugi has one of these with Joey/Jounouchi when Marik takes control of him. Also Jounouchi to Mai in Season 4, the latter [[spoiler: having to lose his soul just to snap Mai back to normal.]]
* IllGirl: Shizuka/Serenity.
* InTheEndYouAreOnYourOwn
* InactionSequence: Very, very often.
* InadequateInheritor: Gozaburo to Seto.
* IndyEscape: {{Subverted}} during Duelist Kingdom. The boulder in question was just a balloon with a speaker in it.
* IneffectualLoner: Seto Kaiba.
* InformedAbility: The Kaiba brothers -- for all of their supposed awesome skill at playing their favourite games they tend to fall for very simple ruses. Mokuba and Yugi's Capsule Monsters match was an especially blatant example.
** There's a reason why we never see Yugi and Seto play chess. King of games or not, but you can't use the heart of the chess piece to win a game. And there are no power ups (other then promoting pawns, which isn't too hard to see coming) or convenient special abilities.
** Rex Raptor and Weevil Underwood were in a tournament championship facing each other right before the Duelist Kingdom arc. Yet from then on out they never pose much of a threat to, well, pretty much anyone, effectively becoming recurring joke characters who sure don't look like champions of any level of tournament.
*** Rex is an unfortunate case. Of all the duels he lost in the canon arcs almost all of them were against opponents who were willing to cheat or against Joey (who won by dumb luck). Admittedly we don't see anything to suggest that Weevil cheated in their first duel but considering that it was Weevil who threw Yugi's cards into the ocean it wouldn't be too surprising.
*** The same could be said of Weevil/Haga really. Other than that, Weevil went up against Yugi/Yami Yugi twice and did very well both times. Certainly Weevil cheats but he's still shown to have great skill. The cheating only seems to serve as a supplement to his own abilities, or because he [[ForTheLulz enjoys it]]. Other than [[BornLucky Joey]], Weevil's only ever lost to [[SuperWeight exceedingly great duelists]]. The main reason he becomes a joke character is because he's a SmugSnake who CantCatchUp as far as powerful cards go.
* InstantAwesomeJustAddDragons: The most powerful cards in the game are dragons, and it was carried over to the sequels. The villain in the crossover movie with ''GX'' and ''5DS'' summon nothing but dragons, to show how superior they are to the audience. Even Kaiba (the most dragon-obsessed guy in the series) has some variety in his deck.
* InsultToRocks: "You know, I'm not quite sure what to call you. I was thinking about 'monster'... but I wouldn't want to insult the cards."
* IntergenerationalFriendship: [[ReallySevenHundredYearsOld Big time.]]
* [[InterplayOfSexAndViolence Interplay of Sex and Card Games]]: Yami Malik seems prone to causing this.
* InvincibleIncompetent: Katsuya Jonouchi (Joey Wheeler) perpetually comes from behind to win. Granted, everyone does this, but Joey never seems to be picked as a favorite to win anything, despite several finals showings.
* IronicEcho: In season one, Kaiba threatens that he'll fall from the castle's battlement if Yugi wins the duel, so Yugi forfeits in fear that Yami would finish Kaiba off.. In season five, Yugi again faces the decision of defeating his opponent in a duel to kill him. In this case, the opponent is [[spoiler:Yami]]. Yugi hesitates on finishing the duel, but carries it out, as this time, the reason is [[spoiler:to send Yami to the afterlife]].
* IWillShowYouX: When Tristan has an open crush on Joey's sister Serenity, which Joey is [[BigBrotherInstinct none too pleased about]]. At one point in the English dub, Tristan talks about how he's going to visit Serenity (read:hit on her) in the hospital, to which Joey responds "''I'll'' send you to the hospital!"
* ItMeantSomethingToMe
* JerkAss: Kaiba.
** Bandit Keith is a bigger one. He and his {{mooks}} trapped Yugi and the gang in a cave, and he also stole Jounouchi's Glory of the King's Hand card while he was sleeping.
* JerkWithAHeartOfGold: Jounouchi/Joey and Honda/Tristan.
* JokerJury: In the dub version of the Virtual World arc, Johnson, whose Deckmaster and appearance is that of Judge Man, claims he is putting Joey on trial for gambling.
** He then proceeds to make every trial joke imaginable.
* KarmaHoudini: Ushio, compared to the original manga. In the anime, nothing is really mentioned on what happened to him after the flashback to the scene where he beat Yugi and his friends up. The dub did add in a very quick line where school authorities found about him and properly punished him, but in the original version never says anything beyond that, arguably implying he got off completely scot-free for what he did.
* TheKidWithTheRemoteControl: In the Toei anime Capmon story, [[spoiler: Haiyama manipulates Kujirada into doing his bidding ]]
* KickTheDog: During a duel using the Orichalcos, Weevil makes the mistake of claiming he has Yugi's soul in his hand, then tearing it in front of Dark Yugi (which was really a normal bug monster card, that made it much worse as he was using it as a way to [[BreakTheCutie mess with the already broken duelist]]), this [[KickTheSonOfABitch does]] [[NoHoldsBarredBeatDown not]] [[MomentOfAwesome end well for Weevil.]]
* KillerYoYo: Hirutani's gang in one story in the manga and one story in the Toei anime
* KnightTemplarParent: This is about the nicest description possible for the way Gozaburo Kaiba raised his children. Although it was probably really just the company he was worried about.
* KnowWhenToFoldEm: Mai does this with Tea at Duelists Kingdom, and later in the Duelist Kingdom finals, when facing Yugi. Both times she says she doesn't have a monster strong enough to take down what the opponent had on the field.
* LargeHam: Pegasus, in the original manga, anime, and dub versions.
** Dark Yugi, especially [[Creator/DanGreen in the dub.]]
** Dark Marik.
* LawyerFriendlyCameo: [[SaintSeiya Seiya and Shiryu]] make a cameo [[http://www.youtube.com/watch?v=s2drZLj4obQ#t=5m34s here]]!
* LethalJokeItem: Some cards are weak or nearly-useless on their own but devastating in the right circumstance. For example, the Ojamas, three monsters with 0 Attack, but have a support card that can wipe out all opposing monsters, spells, and traps, and can fuse into a potent defensive wall. Or the four VideoGame/{{Parodius}} monsters, each with minimal ATK and DEF, but which can combine with one another as Union Cards to have absurd ATK and DEF.
** Baby Dragon was the earliest example. It starts with only 1200 ATK, easily destroyed, but with Time Wizard, it becomes Thousand Dragon, with 2400 ATK, stronger than most cards in the game at that point.
* LetsFightLikeGentlemen: They settle every conceivable difference via a ''collectible card game'', for cryin' out loud!
* LettingTheAirOutOfTheBand: Happens during Yugi's final duel with Marik. [[spoiler: He uses Obelisks ability to destroy Ra. The triumphant music starts playing and it seems he won only for the smoke to clear and revealing Ra to still be alive making this trope ensue.]]
* LighterAndSofter: Compared to the manga.
** And within the anime, the KC Grand Prix. A [[BreatherEpisode breather arc]] with a campy villain whose crime is [[ArsonMurderAndJaywalking not mine-rape, not soul-stealing, but hacking into Kaiba's computer system.]]
* TheLoad: Mokuba. Serenity. Also Tea and Tristan, who were pretty much just around to provide moral support ([[LampshadeHanging Lampshaded multiple times]]).
* LovelyAssistant: StageMagician Arkana was in love with his Lovely Assistant, Catherine, and they were engaged--before his disfiguring accident. Although Catherine still loved him, Arkana pushed her away. He later regretted his choice and fell in with Marik when he promised he could restore Catherine to him.
* LoveMakesYouEvil: Pegasus' motive. Also Akunadin to some extent.
* LoveMartyr: Odion.
* LukeIAmYourFather: Akunadin and Priest Seto in the Memory World Arc.
* LullDestruction: Compare the Dub to the Japanese version. Some scenes have added dialogue especially if in the original, the characters are originally silent.
* MagicalEye: Pegasus's Millennium Eye, possessing the power to read minds and probably do other sinister things. According to WordOfGod, it also [[{{Brainwashed}} brainwashed]] Pegasus into creating Duel Monsters, making it a literal evil eye.
* TheMagicPokerEquation: Arguably Yu-Gi-Oh's central trope, where "important" players have an uncanny ability to draw the ''only'' card that will help them. Some adaptations present that drawing is a matter of skill, determination and faith, and the duelists are aware of this fact.
** Episodes 41 and 42, while an otherwise unremarkable pair of filler episodes, shows Yugi and Rebecca's duel, which apparently goes ''exactly'' like a duel their grandfathers played decades earlier, turn for turn, card for card.
** Lampshaded in the anime arc ''Waking the Dragons'', along with PlotArmor, in the English dub by Rex Raptor/Dinosaur Ryuzaki, when he and Weevil Underwood/Insector Haga witness Yugi use the Eye of Timaeus with Dark Magician Girl. He mentions how Yugi and company tend to draw the cards they need at the right moment, but he and Weevil don't.
* MarkOfTheBeast: If a character has a glowing eye symbol on their forehead, has MindControlEyes, and talks in a [[VoiceOfTheLegion creepy superimposed voice]], it's most likely that Marik is [[BodySnatcher remotely possessing them]] using his [[ArtifactofDoom Millennium Rod]].
** If you find someone with a green circle on their forehead, they probably want your soul so they can feed it to their ancient beast.
* MeaningfulName: Happens for a couple of characters, particularly the (ancient) Egyptian ones:
** If Marik's name were [[SpellMyNameWithAnS transliterated]] differently when moving into the English dub, it would be the Arabic name [[http://www.behindthename.com/name/malik Malik]] (or "ملك" in Arabic), which is based on the words for "king" or "possessor" in the Arabic language. Incidentally, Marik [[BodySnatcher possesses]] several people and [[TakeOverTheWorld wants to be the pharaoh/king of Egypt/the world]] as a BigBad.
** Also Odion's name in the Japanese version is [[http://www.behindthename.com/name/rashid Rashid]] (or "راشد"), meaning "rightly guided" in Arabic. Odion/Rashid is Marik/Malik's older adopted brother and serves as one of his two [[MoralityPet Morality Pets]] in the series.
** Shadi's name is only a phoneme different from the ancient Egyptian word ''[[http://www.ancientegyptonline.co.uk/shabti.html shabti]]''. ''Shabti'' are figurines placed in tombs among funerary goods so they can be servants to the tomb's owner in the afterlife. Using representative figurines replaced killing [[PoweredByAForsakenChild actual]] [[HumanSacrifice servants]] for this sole purpose. Shadi guards the Millennium Items' original resting place and [[spoiler: [[DeadAllAlong turns out to be just a ghost]] since Yami Bakura had killed him 5,000 years ago when he was one of Atem's priests.]] And like Malik's and Rashid's names, the name "Shadi" is also [[http://www.behindthename.com/name/shadi-1 Arabic]] in origin, [[ShownTheirWork reflecting]] that all these characters come from modern Egypt where Arabic is the official language.
** There's also Ishizu, named after the ancient Egyptian goddess [[http://www.touregypt.net/magazine/mag08012001/magf5.htm Isis]]. Isis is the queen of [[ReligionIsMagic magic]], [[DueToTheDead dedicated wife]] to her murdered and undead husband Osiris, and honored for being a [[MamaBear good mother]] to her son [[{{Protectorate}} Horus]]. Ishizu is a MysteriousWaif of a character who can [[SpiderSense see the future]] using her [[AppliedPhlebotinum Millennium Necklace]]. One of her major goals is to stop her [[FaceHeelTurn Face Heel Turned]] younger brother Marik from being [[BigBad villainous]]. She is also another one of Marik's [[MoralityPet Morality Pets]].
** "Yugi" means "game"
*** Yami means dark or shadow, which means that "Yami Yugi" means "Shadow Game."
** Oh, also, the whole Yu Jou thing. Take the initial syllables of Yugi and Jounouchi's first names and you get the Japanese word for "friendship." (Which manifests itself in real life as the "Yu Jo Friendship" card.)
** And the fact that Seto Kaiba, the most dragon-obsessed guy in the cast's surname translates to "sea dragon." On a related note, the same guy's first name translates to "shallow man."
** There's an even weirder couple of meanings behind his name. "Seto" is basically the Japanese pronunciation of "Set". Combine this with Yugi's name ([[IncrediblyLamePun "Game", "Set", Match]]) for one meaning, but for the other, Set was the Egyptian desert god, a completely appropriate name for a [[spoiler:high-ranking ancient Egyptian priest]].
** Possibly unintentional, but the English surnames for Jonouchi, Anzu and Honda are all occupations: Wheeler, Gardner and Taylor.
** Yami's real name [[spoiler:Atem is a variation on Atum, as in Atum-Ra. The creator god, the god of the sun, the first king of the gods, the first pharaoh, etc. Oh, and he apparently had a Winged Dragon, too.]]
* MindScrew: The Memory World arc is a mild version. In ''general'', things make sense and you can follow what's going on, but some really bizarre stuff happens too.
** Shadi, good lord.
* MikeNelsonDestroyerOfWorlds: Everything that's happen is because Yugi wanted a friend, poor kid.
* {{Mondegreen}}: No, [[http://www.youtube.com/watch?v=ErCUh8Z-uO4 the dub theme]] is not misspelling Yami as [[EarWorm Yamu]], it is actually ''Your Move''.
* MoralityPet: Mokuba Kaiba.
* MoreThanMindControl: Dartz in Season 4.
* [[TheMovie The]] SoBadItsGood [[TheMovie Movie]]
* MsFanservice: Mai Valentine and Dark Magician Girl.
* MulticoloredHair: Yugi, and his grandfather.
* MundaneMadeAwesome:
** "Card games are serious business."
** Dramatically animated belt clipping-on sequence?
* MusicalPastiche: The track [[https://soundcloud.com/theshugotv/yu-gi-oh-bgm-the-priests "The Priests"]] in the Japanese OST is a pastiche of [[http://soundcloud.com/theshugotv/cyberteam-in-akihabara-bgm the transformation theme]] from CyberTeamInAkihabara, it's not too surprising since both show's share the same composer, Shinkichi Mitsumune
* MusicalSpoiler: As if the LikeYouWouldReallyDoIt nature of the scene is not enough, the lack of the "Life Points hitting 0" sound effect when [[spoiler: Dartz brings Yami Yugi's LP down to 0]] makes it very obvious that the duel is not over.
* MyLittlePanzer: Duel Monsters is such a safe game for little kids, isn't it?
** {{Subverted}}: By itself, the game is perfectly safe; it's the duelists like the Ghouls that add in their own, more dangerous, rules or invoke the dark magic of the Millennium Items that make it so [[DepartmentOfRedundancyDepartment dangerous]].
[[/folder]]

[[folder:N - Z]]
* {{Necromantic}}: Pegasus.
** Arkana/Pandora.
* NecessaryFail
* {{Necromantic}}: Pegasus got his StartOfDarkness after his beloved Cyndia passed away and he vowed to bring her back.
* NeverSayDie: In the English dub, at least.
** Except for Episode 8 where Kaiba tells Pegasus' men he'd rather die than be captured and promptly leaps to his supposed death, which is mentioned in the next episode where Yugi duels Kaiba's "corpse".
** Also in Episode 13, when Tristan is first sent to the Graveyard.
---> '''Tristan:''' According to this tombstone, I'm ''dead''!
* NewPowersAsThePlotDemands: Frequently, characters reveal to have cards in their decks that they never used before (and never will use again), but which help them win the current duel.
** The Winged Dragon Of Ra is especially guilty of this; it seems like every time [[BigBad Yami Marik]] plays it, Ra just happens to have a previously-unused power that just happens to [[NotSoFastBucko perfectly counter his opponent's new winning strategy]].
* NewRulesAsThePlotDemands:
** Duelist Kingdom is this writ large. Some make at least a bit of sense, like flying monsters having an advantage over land-based monsters, or machine monsters rusting due to a mist over the field. Others just plain have no basis in fact at all, most prominently the infamous Catapult Turtle move Yugi uses to defeat Panik. However, Duelist Kingdom is stated to use custom rules specific to the tournament.
** Once the rules were written and pinned down in Battle City, this turned into "New Cards As the Plot Demands," with duelists producing cards never before seen at just the right time. Many of these cards exist for RuleOfCool, as there are other pre-existing cards that do the same thing as the new card but don't fit the theme of the duelist's deck. Change of Heart for example has equivalents with Yugi and Kaiba in the forms of Brain Control and Enemy Controller. And lapses of the random new rules still occurred: Jinzo is supposedly immune to Time Wizard's effect due to being made of special metal, for example, and Flute of Summoning Dragon lets both players summon Dragons from their hand if they want.
** There's also a ton of cards that were created to allow the duelists to draw cards so the writers can keep their hands filled, such as Card of Last Will, Card of Demise, Nibelung's Ring, and ''especially'' Card of Sanctity. Kaiba's "Power Balance" in particular is ridiculously overpowered in this regard, requiring the opponent to discard half their hand and then allowing the user to draw the same number of cards discarded, all with no drawbacks. But hey, it added tension to his duel with Yugi so why not? Though it doesn't beg the question why he only uses it once.
** With 2-on-1 and later 3-on-1 duels throughout the franchise, the rules are never ironclad, sometimes the lone player gets more turns, sometimes more Life Points, or no advantage at all. A few times it seems that the lone player chooses their advantage, which of course is ridiculous. This is particularly blatant in ''5Ds'' where in on 2-on-1 duel, the lone player began with 10 cards in his hand to cover the disadvantage, when his deck theme is based around destroying his own Trap cards to deal a First Turn Kill. No prizes for guessing what he tries to do, and would have succeeded at if not for the predictable debut of cards that negate effect damage.
* NietzscheWannabe: During the duel between Joey and Yugi in the Duelist Kingdom finals, Pegasus's narration, at least in dub town, slips into this. To quote:
** "Oh, I know you'd like to think that your friendship would be enough to sustain you through any mishap or misfortune, but that's not the way the world works."
** "... when fate hits you with a cold slap of reality and shows you who's boss. Yes, the world has taught me that only the strong and the ruthless survive."
** Kaiba is seen ''reading'' Nietzche in his first appearance. ([[http://www.yu-jyo.net/001/001.shtml In the Japanese, at least.]]) No better way to paint yourself a villain immediately, aye?
*** Maybe. Maybe not. Anyone who reads Nietzche and truly understands his philosophy would know how to be the {{Ubermensch}}, a character that some would think is a villian, but can be a hero (think Batman).
* NoKillLikeOverkill: Numerous times, characters will pointlessly weaken themselves in order to boost their monsters powers or completely clear the field before delivering a final blow so that not only do their opponents life points drop to 0, but all their monsters are gone too - this being in situations where they could save themselves the trouble and just attack outright and win.
** A prime example is Atem's fight with Weevil, after the latter [[BerserkButton pretended to destroy Yugi's soul]] just to [[ForTheEvulz get a rise out of the Pharaoh]]. Atem used a card that let his monster attack directly every time he drew a monster card, and proceeded to pound Weevil again and again, long after his Life Points ran out. He would've kept going too, if [[WhatTheHellHero Tea hadn't stopped him]]. Note that this is during a special duel where ''you actually feel the pain of attacks''.
* NobleDemon: Seto Kaiba.
* NonHumanUndead: In the first tournament, Yugi defeats Kaiba's Blue Eyes Ultimate Dragon by fusing his Mammoth Graveyard into it... which, because both are incompatible types, slowly weakens the resulting fusion and will cause it's eventual death. After this, the rule is never referenced again.
** Another example are Bonz's monsters brought back from the grave.
* NotADate: Anzu/Tea goes on one of these with the Pharaoh.
* NotJustATournament: Virtually ''every'' TournamentArc, to the point where it's commented in-story how refreshing it is to go to a tournament that's ''only'' a tournament (it still manages to get hijacked by a villain's scheme, but at least that wasn't in the host's plans).
* NotTooDeadToSaveTheDay: Yugi gets help from all his [[TakenForGranite petrified]] friends and Kaiba) in his head before playing his last turn in the duel against Noah.
* ObviousTrap: The point of Odion's deck is to focus on laying tons of trap cards and then wait for the opponent to spring them. Thing is, he makes the point to play almost no monsters thereby leaving him wide open to attack except for his traps, which you ''know'' will protect him, he's not stupid. Unless you pack an insane amount of spell/trap destruction or run an unorthodox deck theme, you're gonna have to attack him sooner or later, and when you do, he'll be ready to turn it back on you. Joey found this out the hard way.
** Joey and Mai later learn Marik also plays a lot of traps, which are even more brutal and painful than anything Odion used.
** Besides the specific duelists, quite often the characters [[GenreSavvy know the opponent has a dangerous trap waiting]], but they acknowledge if they want to win they either need to find a way around it, or trigger it and hope they can come back from whatever it does.
* OffModel: Several moments. These actually make some of the more threatening characters ''even scarier''.
* OffscreenMomentOfAwesome: Yugi vs. Jonouchi immediately after Battle City, even if we know Joey won (he was battling Yugi for his Red-Eyes and is shown to have gotten it back). Both mediums skip this.
* OhCrap: Being on the receiving end of a spell, trap, or ability that they [[DidntSeeThatComing didn't see coming]].
* OlderIsBetter: The older your magic, the better it is.
* OlderThanTheyLook: Yugi.
* OddlyNamedSequel: ''Anime/YuGiOhGX''; ''Anime/YuGiOh5Ds''; ''Anime/YuGiOhZEXAL''[[note]]pronounced "Zeal" in the Japanese[[/note]].
* TheOnlyOneAllowedToDefeatYou: To the point where Kaiba throws a hissy fit upon learning Yugi has 'allowed' someone else to defeat him in Season 4.
* OutrunTheFireball: At the end of the Virtual World arc, Kaiba presses a BigRedButton, sacrificing the greater part of his blimp to accomplish this.
* OrgasmicallyDelicious: Bakura's steak, [[http://kokorononaka.net/FAQ/v23-143s.jpg in the manga]]. In the anime, it was more CrazyConsumption.
* OrphanageOfFear: According to Kaiba, at least.
* OvertookTheManga
* PantyShot: Joey and Tristan randomly lifting up Tea's skirt in class and yelling "Panty tank!"
** Also in Season 0, Joey uses a Yo-Yo to accidentally cause a dangerous flurry of wind toward Anzu and Miho.
* ParentalAbandonment
* ThePasswordIsAlwaysSwordfish: Pegasus isn't very password-savvy, is he?
** Well, in his defense, the place where the password needed to be entered was so far into the program that it seemed impossible that anybody could get that far. Shame that Kaiba isn't just "anybody".
** In the original anime, the password is "Alcatraz," which matches the scene - an island prison which, once entered, can never be left.
* PensieveFlashback: The Kaiba brothers experience these in spades during the Virtual Nightmare arc.
* PhantomZonePicture: People's souls were trapped within the cards.
* PinballScoring: Every card in the anime does base damage/bonuses/etc in increments of 100; the actual card game has a handful that have 50s.
** In the Duelist Kingdom season, there were a few duels where damage/bonuses were calculated by percentages of other stats, creating some odd prime numbers. From Battle City on, most all the numbers ended in even 0's.
** Unless you're Marik, in which case you can have attack points that end in --99.
** A few monsters have ATK or DEF stats that aren't divisible by 50. Castle of Dark Illusions has 920 ATK and 1930 DEF, Reaper of the Cards has 1380 ATK and 1930 DEF, King of Yamimakai has 2000 ATK and 1530 DEF, and Seven-Armed Fiend has 666 ATK and 666 DEF (1000/1000 in the Dub). All but the last are the result of the anime fudging the numbers of the Player Killer of Darkness's monsters so that they get a field power bonus.
* PintsizedPowerhouse: Yugi.
* PlotTumor: The ultimate one, possibly. Originally, the manga ''was not about any specific game'', much less a single card game. He's supposed to be the King of Game'''s'''.
** Lampshaded in The Abridged Series. Yugi is just referred to as "The King Of Card Games".
** To be fair, after the point where the PlotTumor hits, the card game is only played during Duelist Kingdom saga, the Battle City saga, and the Ceremonial Battle. In the manga, the Dungeon Dice Monsters saga and the Pharaoh's Memory saga are almost completely devoid of Duel Monsters. It's much more prevalent in the second series anime, where even flashbacks to chapters where the card game ''wasn't even introduced yet'' in the manga were altered to involve cards. This also doesn't stop every other related spin-offs from focusing exclusively on the card game after the original manga ended.
* PoweredByAForsakenChild: Creating the Millennium Items required a sacrifice of 99 human lives.
* PowerLevels
* PowerMakesYourHairGrow: When Yugi, Bakura and Marik become possessed by the spirits of the Millennium Items (or in Marik's case [[spoiler: his SuperPoweredEvilSide]], their hair gets even more ridiculous than usual.
* ThePowerOfFriendship: Prior to the card game PlotTumor, this was going to be the main theme of the series. It still has a fairly strong presence. Occasionally to the point of {{narm}}.
** WordOfGod says that it was the intended main theme the whole way through. The card game PlotTumor just created alot of MisaimedFandom, that's all.
* PowerTrio
** BeautyBrainsAndBrawn: Shizuka, Anzu and Mai.
** BlondeBrunetteRedhead: Mai, Anzu and Shizuka.
** FreudianTrio: The Doma arc.
*** TheKirk: Yugi/Yami
*** TheMcCoy: Jounouchi
*** TheSpock: Kaiba
* PragmaticAdaptation: Some actually ''prefer'' [[http://www.youtube.com/watch?v=DDdUg-5_K2s the English opening]] for the darker and more mythical feel it gives the series, as opposed to the J-Pop opening of the Japanese ones, not to mention the sheer NarmCharm of "It's time to D-D-D-D-D-D-D-D-D-D-DUEL!"
* PrestigiousPlayerTitle: ''Duel Monsters'' players are called "Duelists".
* PrincessesRule: Princess Adina, ruler of Simlow, in Kaiba's virtual world.
* PromotionToParent: Seto Kaiba.
* PsychicPowers: The Millennium Items give their owners a variety of psychic powers, depending on the item. Some examples being mind crushing, [[MindRape mind raping]], locating and identifying other Millennium Item holders, [[{{Telepathy}} mind reading]], [[JourneyToTheCenterOfTheMind visiting someone's mental landscape]], [[SpiderSense seeing the future]], and [[BodySnatcher possessing other people]].
** Don't forget how Bakura used his Millennium Ring to [[spoiler: summon monsters and activate Duel Monsters cards outside of a duel, and sic them on some Mooks]].
* PutOnABus: Bakura. So in this case, it would be more like Villain On A Bus.
** Bandit Keith in the anime, who, after losing his duel with Yugi, is never mentioned in the story again.
* QuestForIdentity: The second series. The pharaoh in particular.
* RageQuit: Several times, low rank villains will screw the rules and attempt to get their job done directly. This has had varying levels of success.
** This is especially fatal in a Shadow Game, which enforces the rules very strictly and very harshly.
* {{Railroading}}: This is the basic explanation for the series and why the main characters who are losing always seem to pull impossible card effects at just the perfect time.
* RapidFireTyping: Seto Kaiba often utilizes this whenever he's operating or hacking into a computer.
** Parodied in ''WebVideo/YuGiOhTheAbridgedSeries'':
--->'''Computer''': It looks like you're just pressing the same buttons over and over.
--->'''Kaiba''': That's because I learned how to [[HollywoodHacking hack]] by watching old episodes of ''Franchise/StarTrek''!
* TheReasonYouSuckSpeech: Kaiba, most notably.
** To anyone unfortunate enough to lose to him. Joey is victim to this more often than not.
*** Tea, of all people, turns out to be surprisingly good at these, although she doesn't give them often. She gives one to Kaiba at Duelist Kingdom, although it's more of a "the reason Yugi is better than you" speech. Then there's the time she let Johnny Steppes have it for running away when his duel with Yami got too difficult.
* RecapEpisode
* RecognizableBySound: In the Virtual World arc, Noah plays Serenity's screams into the tunnel where the rest of the gang are. Joey instantly recognizes it.
* RedemptionEqualsDeath: [[spoiler:Noah Kaiba.]]
* RedEyesTakeWarning: Hey, did [[ShrinkingViolet Yugi's]] irises just turn red? [[SuperPoweredEvilSide Better start running.]]
* {{Reincarnation}}: Gets rather complicated. [[spoiler: It is ''heavily'' implied that Yugi is the other half of Atem that ''didn't'' get sealed into the puzzle and just sort of floated around until it was born again. Common EpilepticTrees is that [[NiceGuy Ryou]] is something similar in regards to the ancient BigBad Thief King Bakura (who more complicatedly never did a bad deed until being controlled by Zorc, a completely separate being). Seto (with Set) and Ishizu (with Isis) are straighter examples.]]
** It's ''slightly'' less complicated if you look at the Ancient Egyptian concept of soul. One of the key pieces being the "ren" or name implies Kazuki may have done this on ''purpose''.
*** Heck, it only makes it more complicated. Consider how differently Kaa and Baa in season five behave to their Ancient Egyptian counterparts (and don't even try to come to a strict definition of how the soul parts work ''in'' Ancient Egyptian writings). A tip: never sit down with two fans who also like to study Ancient Egypt and ask them whether the series is accurate to Ancient Egyptian mythology or not. They might have matching opinions... or you might end up with a monstrous debate on the topic.
** Well, it was only the dub which decided to call Yuugi [[spoiler: Atem's reincarnated other half]]. In the Japanese version of that scene, Ishizu just said that she believed that Yuugi had been fated to be Atem's host. The real confusion is caused by the [[spoiler: view of almost the whole court when Atem walks through the door to the underworld, even though up till then, Seto and Ishizu had been played as pretty straight reincarnations.]]
* ReincarnationRomance: Seto and Kisara.
* RoadSignReversal: The Marik-brainwashed Bandit Keith has set up arrows to lure Yugi into a trap. Yami Bakura flips the arrows around so Yugi's friends can't follow.
* RousseauWasRight: Numerous bad guys including [[spoiler: Dartz and his biker henchmen, Marik Ishtar, Pegasus etc]] all seem hopelessly callous and evil only to eventually prove to be good at heart, whether by exorcism of an evil side or simple persuasion, usually by Yugi or Pharaoh. Seto Kaiba is also routinely obnoxious and cold yet occasionally proves to have a compassionate side, which is usually related to his love for his little brother Mokuba.
* RuleOfEmpathy
* RuleOfSymbolism: The author intended to have the cards represent the character and personality of their users.
* RuleThirtyFour: Usually done with [[BlackMagicianGirl Dark Magician Girl]], Tea/Anzu, and Mai, but other instances exist.
** Most notable is what the Crump v. Tea duel in the Virtual World arc spawned.
* SadlyMythtaken: An Ancient Egyptian card game, for starters...
* ScrewDestiny: It's revealed in the final arc that one of the Millennium Puzzle's abilities is to "alter fate", which in the context of the Duel Monsters, allows him to change the card he's going to draw as long as he believes it will happen hard enough, rendering every past example of Yugi drawing the exact card he needed by "Believing in the heart of the cards" more than just good luck.
** Kaiba manages this rule in the [[TournamentArc Battle City Arc]]. ScrewDestiny, I have money!
*** He also changes the future itself by following his instincts and [[spoiler:sacrificing his ancient god card to summon a Blue Eyes White Dragon to attack and win his game against Isis, whereas her clairvoyance had predicted he would attack with the ancient god and fall victim to the clever damage feedback trap she had set up. He wins the game instead of losing as destiny had foretold.]]
**** It's actually not instinct. The Millennium Rod reached out to him, recognizing his soul as it's true master and showed him what to do.
* [[ScrewTheRulesIHaveMoney Screw The Rules, I Have Money!]]: The GagDub is the TropeNamer.
** Occurs within the series itself. Kaiba does it, of course. Pegasus, however, even makes special cards that never go into circulation just so that it gives him an advantage.
* [[ScrewTheRulesIHaveSupernaturalPowers Screw The Rules, I Have Supernatural Powers!]]
* SculptedPhysique: Many of the mons.
* SealedEvilInASixPack: An in-universe fictional example is Exodia, a monster so powerful it takes multiple cards to contain him. The individual pieces are worthless, but a player who reassembles Exodia by getting all five parts in play wins immediately.
** And The Pharaoh was trapped in the Millennium Pendant, which was then broken up into pieces. They were all kept in one place, but putting it back together was a complicated process (which is why it was then renamed the Millennium Puzzle).
* SelfMadeOrphan: Kaiba has a [[ParentalAbandonment long]] [[PromotionToParent history]] of [[OrphanageOfFear these]] [[AbusiveParents kind]] of [[SelfMadeOrphan tropes]]. Also Marik.
* SensitiveGuyAndManlyMan: [[ShrinkingViolet Yugi]] and [[TheStoic Yami]], respectively.
* SeriousBusiness: Duel Monsters. The universe runs on it. Didn't you know that?
** Justified in RealLife, where the card game is truly serious business, one could make you some hefty prize money in grand tournaments. The manga & anime series now serves a double role along with being an entertainment medium: strategic documentations!
** Blown to ridiculous proportions in Yu-Gi-Oh! GX, in which it takes an entire navy and air force to deliver a briefcase of rare cards safely to Duel Academy. The Princeton brothers even plan to take over the world through the three pillars of humanity: politics, economics, and Duel Monsters. No joke.
* SexyWhateverOutfit: The Dark Magician Girl wears a sexy RobeAndWizardHat.
* SharingABody: Yami and Yugi. Dark Bakura and Ryou. Dark Marik and Malik.
* ShipTease: Rebecca kisses Yugi early on in Season 4. Cue LuminescentBlush (and he had an awkward expression on his face before she kissed him).
* ShoutOut: Both the card game and anime series feature cards based on Konami's ''{{Gradius}}'' and ''MysticalNinja'' series, and even one that references ''Franchise/MetalGear''.
** First episode, take a look at the shelf that Yugi covers up just as he answers the phone call from Kaiba. Even ''VideoGame/SuperRobotWars'' can find its way into a show about a children's card game.
** ''Yu-Gi-Oh'' has referenced ''{{Dragonball}}'' on three occasions: the first chapter of the manga references ''Dragonball'' by name, when Yugi figures having the Millennium Puzzle grant his wish would be similar to collecting the Dragon Balls. Another instance is that a Dragon Ball poster can be seen in Yugi's room during the Battle City arc. Finally, during the KC Grand Championship, Weevil's and Rex's ambush of Fortune Salim and following masquerade a la TotemPoleTrench replicates a similar scene in ''Dragonball'', where Goten and Trunks use a similar tactic to get into a tournament. There is also Big Bang Shot, which has a picture of Vegeta [[ExactlyWhatItSaysOnTheTin doing a Big Bang Shot.]]
** [[http://www.youtube.com/watch?v=YS6wcAzXhlc One of Pegasus's toons sure loves]] [[Franchise/CrashBandicoot spinning]].
** In a dub-induced case, Mai irritatingly states in "The Gauntlet Is Thrown" that her sleeping conditions on the ship were "Outrageous! Truly, ''truly'' outrageous!", in a bizarre nod to ''WesternAnimation/{{Jem}}''.
** In the dub for episode 95, a movie Marik sees on TV in the outside world has the line, "[[Film/PeeWeesBigAdventure Sorry Dottie, I'm a loner. A rebel.]]"
* SkepticismFailure: Hey, Kaiba. Guess what? Ancient Egyptian trading card game!
* SocialServicesDoesNotExist: Story of the Kaiba brothers' life. Also, the manga implies that Bakura lives all alone.
** That one's more of a self-imposed exile by Bakura, because Very Bad Things keep happening to people around him. At the very least, he still [[spoiler:writes letters to his dead mother and sister]] and keeps in contact with his father.
* SolomonDivorce: Jounouchi and Shizuka.
* SortingAlgorithmOfEvil: Kaiba --> Pegasus --> Marik --> Dartz --> Zorc/Bakura.
* SoulJar: Millennium Ring, Millennium Puzzle, various gaming equipment, [[spoiler:Taken literally with Mai in season 2 when she loses to Marik.]]
** Although "''Soul Jar''" sounds like a good name for a Duel Monsters Spell Card, it's not one. There are some other Jar monsters though.
* SparedByTheAdaptation: [[spoiler:Pegasus]] in the anime.
** Also, [[spoiler:Bandit Keith]].
* SpellMyNameWithAnS: Marik? Malik? In the Bunkoban series, it was spelled Maric.
** Logically it should be Malik, which preserves his MeaningfulName from the original Japanese. Not that that ever stops them from changing things.
** Also Cyndia, although some spell it as Cynthia or Cindia. Then there's her dub name, Cecelia Pegasus, which becomes Cecilia, despite the fact that the proper dub name was shown in episode 40. It gets worse when people assume her original name is Cyndia Crawford, as she does not have a surname in the original.
** The Big Five consist of Ganzley/Gansley, Crump/Krump, Nezbitt/Nesbitt/Nesbit, Lecter/Lector/Leichter... and Johnson.
* SplitPersonality: Not quite, since it's more like another person sharing their body, but it still fits.
** SplitPersonalityMakeover: How do you know who's in control? Well... just look at the page image.
*** Sometimes averted with Bakura, who often seems to be controlled by the spirit even when he looks like his nice self, which the audience usually finds out mere seconds later.
** Played straight with Marik and Yami Marik.
* StepfordSmiler: [[UncannyValley Ryou Bakura]].
* StockForeignName: Vivian Wong.
* StoryArc: Duelist Kingdom, Legendary Heroes, Battle City, Noah's Virtual World, Battle City Finals, Doma, the Kaiba Corp Grand Prix, and Millennium World, with a MythArc spanning all of these arcs.
* StrongerWithAge: The Baby Dragon to Thousand Dragon age up.
** A handful of other monsters, like the Dark Magician, also power-up from the same combo.
*** Subverted with the Harpie Ladies and Red-Eyes.
* SuddenSequelHeelSyndrome: Season 4 turns Mai Valentine into an angst-ridden member of a villainous biker gang. It turns out she was tricked into HeelFaceBrainwashing by Dartz.
* SuggestiveCollision: Happens to [[JustFriends Joey and Mai]] in the episode "Lights, Camera, Duel." Played with though, in that Mai fell on top of him because he was catching her as she fell from a dangerous height--and instead of going for the pervert-slap, [[ShipTease Mai thanks him for saving her and calls him an "action hero". ]]
* SunglassesAtNight: Bandit Keith wearing his sunglasses in a dark cave.
** Because he's an American! And Americans always wear sunglasses!
*** In America!
* SuperpoweredEvilSide: Various characters' Yami versions, including the early appearances of Yami himself.
* {{Synchronization}}: Between the duelists and their cards, to some extent. Showcased when Yugi's grandfather Sugoroku actually has a heart attack when he loses.
* TakeOverTheWorld: Both Marik and Yami Bakura want to do this by usurping the pharaoh position from Yami Yugi, mostly as {{revenge}} for [[ItsPersonal personal]] beefs they have with him.
** [[spoiler: This is further complicated by Zorc's entanglement with Bakura, as Zorc has no beef with Yami, but only uses Bakura's.]]
** Subverted by both Marik/Yami Marik and [[spoiler:Zorc]] in the Japanese versions. Marik merely wants to torment the Pharaoh's spirit as part of revenge and Yami Marik wishes to torture and kill every living thing on the planet. [[spoiler:Zorc is just an evil demon fueled by the rage of the people sacrificed to create him, making him want to destroy everything]]. Even Yami Bakura's motives were unclear and didn't really seem to involve wanting to take over the world in the Japanese version. It eventually becomes clear that he really just seemed to subconsciously desire to collect the Items throughout the manga so he can [[spoiler:revive Zorc]].
* TakingTheBullet: Kisara, [[spoiler: who dies to save Seto.]]
** Earlier in the series, Yami saves Mai and Joey from Marik's Winged Dragon Of Ra by diving in front of a ''fireball'' and blocking it with his body until it dissipates. He promptly collapses.
* TankGoodness
* TheTapeKnewYouWouldSayThat: Is it crazy? No, it's magic.
** For the newcomers, Pegasus duels Yugi in the second episode via prerecorded video tape sent to Yugi's house. Pegasus wins.
*** Actually, he didn't duel through the tape. The tape was enchanted to pull Yugi into a Shadow Game, where the actual Pegasus was waiting. The recording only made the announcement and activated the spell. Straighter in the manga where Yugi doesn't get pulled anywhere (unless the whole living room with his friends and Grandpa got pulled in too and it wasn't noted in any way).
* TattooedCrook: BigBad Marik Ishtar has a large tattoo covering his back and he is the leader of his own criminal organization. [[InvertedTrope However]], it was his reception of the tattoo that had originally caused him to turn to evil, not the other way around with him getting the tattoo after turning evil. The tattoo was carved into his back in the Japanese version, though itís similar, and the dub changes it to a tattoo.
* ThemeDeck: Trope Namer
* ThereAreNoTherapists: Several characters would be better off with professional help. Most notably the villains.
* TheyWereHoldingYouBack: Dartz' recruitment method.
* ThirdEye: The card "Goddess with the Third Eye", and most Millennium Item holders when using their item.
* TookALevelInBadass: Joey/Jounouchi. As early as the Duelist Kingdom arc, he spammed monster after monster without any regard of strategy, because he relied too much on the idea of beating things to death even though the attack stat was too low. It became apparent in the second episode of the show that he lost to [[TheChick Tea/Anzu]], probably the least competitive players of all, because she knew a thing or two about magic and traps. It took a lot of encouragement and guidance on the Pharaoh's part to help him, but by Battle City he grew into a very competent duelist and became a finalist, managing to go toe to toe against [[BigBad Marik]].
* TooManyMouths: Slifer the Sky Dragon has two.
* {{Toon}}: Pegasus' Toon Monsters.
* ToonTown: Pegasus' Toon World.
* TournamentArc: And how. The only arc two arcs that ''weren't'' tournaments were Waking the Dragons and Dawn of the Duel.
** Only with the second series anime, of course.
* {{Tsundere}}: Mai Kujaku/Valentine and Jou/Joey.
* TraintopBattle: Or blimp-top in this case. Played straight in Season 4 when Yami Yugi duels Weevil.
** Also, in Season 5, a ferris wheel-top one.
* TraumaCongaLine: Happens several different times, to several different characters.
* TroubledButCute: Early childhood Seto Kaiba. Also early childhood Malik.
* TruthInTelevision: Pegasus's Toon cards are said by Yugi to be kept out of circulation for being too powerful, but Pegasus is the creator of the game so he kept them for himself. The Seal of Orichalcos, a GameBreaker if there ever was one, exists in real life and is limited to a few copies that were used by members of Upper Deck's R&D department in a special tournament.
** Until years later, when it got an official release to the public!
* UngratefulBastard: Kaiba, after several rescues from Yugi and co.
** He does show some limited thanks for Yugi, and only Yugi, at times, such as freeing him from Pegasus and the Big Five.
* UnstoppableRage: Specifically, after Yugi's soul is taken by the Orichalchos, and Insector Haga ''[[BullyingADragon taunts]]'' the now rather unstable Yami by tearing up a card in front of him after claiming it was Yugi's, just "[[MoralEventHorizon as a joke]]", Yami... well, he goes totally and utterly apeshit, really. He defeats Haga using a card that grants extra attacks by drawing and discarding monsters, and then he continues bashing at him by trashing more monsters long after Haga's lifepoints have hit zero. He would've kept going too, if Anzu hadn't stopped him. [[http://www.youtube.com/watch?v=uYx_sJRmgeY Here's the scene]]... Not pretty.
** There's (possibly deliberately) an added MeaningfulEcho -- the last card in his hand (the one he would have tossed next if Anzu hadn't stopped him) was Dark Magician Girl. Not only was she the card spirit who had asked him for help at the start of this arc, she quite frankly has seen enough of the Orichalcos effect to last a lifetime and could do without watching her master going nuts about it again.
* UtopiaJustifiesTheMeans: Dartz.
* VendorTrash: When the rules got more defined, a lot of the worse cards didn't have DeusExMachina powers anymore and were pruned. Though some of them got updated versions that are useful.
* ViewersAreGoldfish: Hey Yugi, remind me again, what does Pot of Greed do? Or how about flashing back to that play that happened one minute ago for those who missed it? Even if you have no idea how the card game actually works, you can follow every single duel in the later seasons because every single card will have at least ten seconds spent explaining its effect. Even if the card is used every single duel, its effect will be explained. This continued into ''Anime/YuGiOhGX'', right up until Pot of Greed got put on the real-life banned list [[RealLifeWritesThePlot and the anime suddenly stopped using it]].
* VoiceOfTheLegion: Marik.
** Also the [[WebVideo/YuGiOhTheAbridgedSeries Steves]] under his control.
* WaterfallShower: First season has this.
* WeCanRuleTogether: Noah makes this offer to Yugi in the Japanese version of episode 118, after Yugi managed a formidable counterattack and after Noah turned some of Yugi's Nakama to [[TakenForGranite stone:]]
-->'''Noah''': Seriously though, that was ''splendid'', Yugi! You possess both the skill and judgement necessary to catch your enemies off guard the second they lose focus. When you think about it, you and I have no reason to be enemies. If you swear your loyalty to me, I'll save all your friends from hell this very instant!
* WarriorTherapist: Mai during her duel with Yugi in the Duelist Kingdom finals. She manages to talk Yugi out of his funk so that he can duel her with a clear and focused head. And it works! Definitely one of her most brilliant moments.
* WelcomeToCorneria: Both virtual realities suffered from this, despite how fleshed-out everything else in them was. {{Deconstructed|Trope}} in the latter, since Noah had spent ''years'' trapped in his world and was driven mad by this.
* WhamLine: From episode 52:
--> '''Ishizu Ishtar''': And the young man who stands behind the pharaoh... Above his head is [[spoiler: the Blue Eyes White Dragon.]]
* WhatHappenedToTheMouse: Gurimo from the first two episodes of the Waking the Dragons arc. Once he's finished being MrExposition: everybody forgets about him, including his cohorts, even when all of the souls are being restored and only the battle is referenced briefly during Raphael's last fight, prior to his HeelFaceTurn:
* WhatTheHellHero: Rebecca does this to Yami when his reckless use of the Seal of Orichalchos results in Yugi losing his soul. Heck, even WEEVIL does this effectively, pointing out that while he might be an asshole, at least he didn't knowingly endanger his friend simply to win.
* WhiteHairBlackHeart: Bakura and Marik - or, at least, their evil alter egos.
* WineIsClassy: In the original, there's a scene where Pegasus is drinking a glass of wine. For the dub, this got changed to [[FrothyMugsOfWater "the world's finest fruit juices"]].[[note]]Funny enough, this could still allude to it being wine. After all, wine is often made from fruit and would be considered the "world's greatest fruit juice" by some.[[/note]]
* WithFriendsLikeThese: [[http://ygocanonshuffle.wordpress.com/page/3/ Anzu and Honda are complete assholes to Jonouchi in the anime]].
* WokFu: Yugi faces off against Vivian Wong inside a Chinese restaurant. His friends get distracted from their usual PowerOfFriendship cheerleading routine by all the food.
* TheWorfBarrage: Kaiba's Crush Card. Number of times he tries to use it? Seven. Number of times it actually works? Three. And of those three times, Yugi found ways to work around it and lost for entirely unrelated reasons, and Ishizu made its effect work to her advantage and turned it back on Kaiba. So really, of the seven times he uses it the Crush Card only works the way he plans it to ''once''. Though, the one time he couldn't get it off normally, he was able to [[spoiler:combine it with the Fang of Critias]] and win that way.
* TheWorfEffect: The 2nd anime series added several duels for Joey, most of which he lost. The most offensive example being in the final filler arc where he loses disgracefully to the effeminate German FillerVillain.
** Mai Valentine/Kujaku. No, seriously. Top-notch duelist who gets seeded off against the most dangerous opponents, eventually becoming {{deconstructed|Trope}} in Season 4: Despite being a very skilled duelist; she keeps going up against super-powerful opponents to show the viewers how hard it'll be for the other heroes to win. On top of [[TraumaCongaLine what Marik does to her]], she starts to have a breakdown over it (to the point of destroying a first-place trophy she just won), and Dartz is able to [[HeelFaceBrainwashing brainwash her over to the villain side]] because of it.
* WorldOfHam: Especially when two [[HamToHamCombat hams duel against each other]]. The Kaiba/Yami matches go UpToEleven compared to others because of their rivalry.
** If you watch the first few episodes, the ham isn't as big. But the bigger that rivalry got, the bigger the [[IncomingHam ham]] really got.
* YouCantFightFate: Somewhat. Averted in Kaiba's duel with Ishizu.
* YouGottaHaveBlueHair: Some minor characters, and Kaiba in the first anime.
** Although Kaiba's hair is technically green.
* YouMonster: See the trope page quote.
* YouWouldMakeAGreatModel: Happens to Anzu/Tea, who is promised a chance to be a dancer like she's always wanted.
* ZenosRace: Inverted with the pharaoh's backstory, seeing how more information is revealed from the early manga, to Duelist Kingdom, to Battle City, to the Millennium World.
* ZergRush: At one point, Yugi uses Monster Multiply, which causes Kuriboh to multiply each turn, in conjunction with Kuriboh's special ability allows it to nullify the damage done by one enemy monster. Due to there being no limit on how many monsters can be summoned with one magic card in the anime's version of the game, this allows him to create a virtually impenetrable barrier of the little guys.
* ZettaiRyouiki: Rebecca Hawkins manages to pull off a grade-A in her initial appearance. Also, she's twelve years old.
