With this being a [[LongRunner long-running franchise]] about [[FanNickname a children's card game]], it was only a matter of time before they had just activated the dethroning card.

''[[AC: Anime/YuGiOh]]''
* Tropers/{{Demetrios}}: While I [[GuiltyPleasures admittedly enjoyed]] the [[{{Filler}} unpopular]] DOMA/Atlantis arc of ''Anime/YuGiOh'', there was one part I wouldn't blame my fellow fans fans for not liking. When Mai was corrupted by the [[ArtifactOfDoom Orichalcos]] and Joey was understandably heartbroken about it, Tristan basically told Joey to, pardon my French, [[NoSympathy go fuck himself]]. Well, actually, he didn't quite say it that way, but he seemed to be trying to convince Joey as if Mai was pure evil [[TheFarmerAndTheViper and thus not worth saving]]. Note that under the circumstances, that isn't quite the same as [[SomeAnvilsNeedToBeDropped telling your friend something important without sugarcoating it]]. That's just nasty and mean-spirited. I know people weren't too keen on Tea's friendship speeches, but isn't that going a little too far?
* Tropers/{{LLSmoothJ}}: Speaking of Joey, the [[{{Filler}} KaibaCorp Grand Prix]] treats him even worse as he becomes the butt of a joke based on a card in Yugi's deck (which even [[WithFriendsLikeThese his friends]] laugh about). Even worse, in the tournament, his [[CantCatchUp decline]] continues as he loses within the second round (I know it was to the BigBad of this arc, but still, Joey was supposed to have become incredibly strong post Battle City, and the arc's BigBad wasn't the kind of person who should be flooring him that easily) of the tournament (he won the first round against Yugi's Grandpa, which may bring up a debate whether he let him win or not). It's bad enough he was already made into [[OvershadowedByAwesome the]] [[Franchise/DragonBall Krillin]] of ''Yu-Gi-Oh'', but now the [[ButtMonkey Ya]][[FailureHero mc]][[TheWorfEffect ha]] as well? Make you wonder if Joey's treatment is to [[PanderingToTheBase pander to Kaiba's fanbase]]. Protip, writers: When you make a character into the second-most important person in the series, you must treat him accordingly. You don't give him second chair to fucking Seto.
* Tropers/{{Dashguy}}: On the topic of CharacterDerailment in the DOMA arc, there's Yami Yugi's duel against Raphael. To make it short: Raphael gets the upper hand, gives the "Seal of Orichalcos" card to Yami Yugi and [[HannibalLecture tells him that since he's "evil" he has to use that card]]. Note that, at this point, the only danger in dueling came from the above mentioned "Seal of Orichalcos" card which would drain the soul of the loser; so you would expect Yami Yugi to tell Raphael to fuck off and keep playing right? Nope. He uses the card, loses and Little Yugi ends up sacrificing his soul in his place. This is a case of AesopAmnesia, with reference to the lesson Yami learned about winning at all costs back in Duelist Kingdom.
* Tropers/{{Ciel12}}: Same moment, but for a slightly different reason. Not only is the AesopAmnesia, but it's out of character and character derailment. When Yami was going to want to go through with potentially killing Kaiba, he was doing it because he felt under pressure to save Yugi's grandfather - in other words, most of his freakouts about losing tend to happen because he takes responsibility and has to fight for something or to protect someone. This also happens way after he grew out of his more gung-ho/illogical tendencies towards winning. But that isn't the case here - in fact, by playing the Seal he's putting his friends in danger, since whoever's soul is taken will powerup the Leviathan. This just doesn't make sense as something he would do, and while the English dub has him saying that he must do it, because otherwise 'two worlds will be in peril', there's no clarification of why and no clearly established stakes. What could have been great character development for an invincible character dealing with losing is squandered as his reason for playing the Seal is never clarified, and unlike the moment in Battle City where he spared Bakura there's no definitive growth/resolution/progression. The Japanese implies he does it to prove that he doesn't have darkness in his heart and wasn't an evil Pharaoh, but this goes against earlier characterisation since he hasn't denied the possibility that he could have been a bad person in the past in previous episodes. When Marik confronts him about his family, he immediately assumes it's his fault and he did something bad to Marik's family in the past based on little evidence. A lot of my problem here is the Japanese making out like Yami is on the edge of being a villain because of his arrogance, when it's blatantly obvious that he is, at heart, an anti-''hero''. He has taken responsibility for things he didn't have to previously, and while he can be overconfident and push his beliefs on others, he doesn't have Kaiba levels of arrogance or refuse to admit wrongdoing on his part. It's filler cheating its characters (as it does with Mai) for the sake of melodrama pathos.
* RAZ: Speaking of the DOMA story, the one real Dethroning Moment for me is the ending battle against the Leviathan. Okay, so Yami Yugi's awakened the three Legendary Knights, the ones that are supposed to be able to destroy the beast, right? Wrong! They get completely curbstomped and eventually destroyed so the Egyptian Gods can come in for the final battle instead, meaning the entire purpose of the Knights was utterly friggin pointless! Oh, but it gets better: right before the battle, both Kaiba and Joey had their souls recovered after previously losing them and return to aid Yami Yugi. So awesome moment of them delivering some payback for nearly being absorbed like the other duelists all were? Not so much, because the attacks from their own monsters get shrugged off and they both eventually wind up getting absorbed by the Leviathan anyway! So... what the hell was the point of reviving them in the first place if that's all they were going to amount to?!
* Tropers/{{EDP}}: For me Kaiba's dethroning moment comes during his duel with Yugi at the Duelist Kingdom: when Yugi was about to defeat him, Kaiba declared he'd take a step back for any 100 HP he'd lose to try and convince Yugi to not attack and gain the turn he needed to win... But he had the [[http://yugioh.wikia.com/wiki/Negate_Attack Negate Attack]] card deployed, meaning he could have [[ExactlyWhatItSaysOnTheTin negated Celtic Guardian's attack]] and get his turn to attack ''without playing drama queen''.
* Loekman3: For me it's how the narrative treats Yami's decision to tribute his monsters for Catapult Turtle's effect damage against Rafael. It's somehow treated as an evil move when he does it but the thing is, no matter how much the series tries to treat it, Duel Monsters is still just a card game and in real life, it's a legitimate tactic if you want to inflict the last amount of life points to your opponent. Furthermore, what could Yami do during the three turns of no attacking aside from the method in the duel? Sit down and do nothing while his opponent has three free turns of doing anything he wants? Chances are by the time those turns passed Rafael would potentially drew a winning card that would have caused the Pharaoh to lose his soul. He only lost because of a lucky draw that somehow manages to turn the Pharaoh's strategy against him. There may be other moments of ProtagonistCenteredMorality but none are as blatant as this one.

''[[AC: Anime/YuGiOhGX]]''
* Tropers/LilyNadesico: The ending of Season 3, where [[StalkerWithACrush Yubel]] pulls a complete KarmaHoudini and gets to be reunited with Judai, and Judai promises to only love him/her for all time - [[TheBadGuyWins which is exactly what Yubel wanted]]. Well, isn't this the greatest EsotericHappyEnding I've ever seen? Screw the FreudianExcuse, in my mind Yubel is an unsympathetic villain and Judai should have rejected him/her with no question asked, perhaps even throwing a ShutUpHannibal at him/her.

''[[AC: Anime/YuGiOh5Ds]]''
* Retloclive: Yusei vs. Kalin (Kiryu)'s first duel ending because Yusei's D-Wheel falls apart before Kalin's winning attack was as lame as it gets to make sure that the hero can't lose a duel involved with the main story. This should have easily been Yusei's first legitimate loss, but ends up counting as an unfinished duel even though it was so bloody obvious that the duel was on the verge of concluding...PlotArmor at its worst.
* Tropers/{{Valkir}}: Despite the other problems in the series, the finale to the Team Unicorn duel tainted 5Ds beyond all recognition. Yusei is down to no cards in his deck and all Jean needs to do is end his turn for a win, delivering the first true loss to an otherwise InvincibleHero. All this time, Jean's team has been all about using team strategy for the good of everyone. But Jean is suddenly...er...[[HoYay passionate]] about his duel with Yusei and suddenly feels the need to attack him, which his team inexplicably supports. He runs into a defensive monster that Yusei boosts with Fortress Warrior and Yusei pulls away with a win despite deserving to lose in every single way. We're supposed to believe that team victory between three people that are extremely cohesive and genuinely care about one another is less important than one superstar flexing for his friends, despite that the former resonates with the themes of the franchise far more than the latter. Yusei's plot armor actually hypnotized Jean into losing. "End your damn turn, Jean" has become synonymous with "jumping the shark" in the fandom. The worst part? It wasn't singles elimination, so Yusei's team had no story requirement to win at all...they could've won their next match and still stayed in the plot.
** Tropers/JediMasterYusei: To say nothing of [[TheyWastedAPerfectlyGoodCharacter what happened to Aki/Akiza in that duel]]. She finally gets a chance to shine again after being DemotedToExtra for the majority of the season...[[CurbStompBattle only to lose to Andore/Andre in 2 turns]]. [[FlatWhat Seriously?!?]] She's the goddamn Black Rose! I could think of at least 5 different ways she could've schooled his ass! But no, she gets [[TheWorfEffect tossed aside just to so how "unstoppable" these guys are]] (even though they already did the same with Jack) so that [[InvincibleHero the almighty Yusei]] can swoop in and look awesome by single-handedly annihilating all three of them. Look, I admit Yusei is my favorite Yu-Gi-Oh! protagonist aside from Yugi himself ([[CaptainObvious just look at my user name for Christ's sake]]). But there's badass, and then there's CanonSue. And you're treading dangerously close to the latter here, guys. At least let the lady take down one of them.

''[[AC: Anime/YuGiOhArcV]]''
* Tropers/{{bubblesishot46853}}: The Arc League Championship is about to begin, and the kid trio are participating in their own division! Surely, we can expect lots of character development from them and see what cards they run. Oh look, Frederick won his duel easily, and now it's Ally's turn, and she's going up against a new character we know nothing about...what? She lost? Well, ain't that dandy. Not only did another favorite character of mine lose right when a tournament begins again, but she lost to a character with no buildup other than a mention that he's Declan's younger brother. To make matters worse, he ends up winning the Youth Division, being selected for the Lancers, and continues to floor every duelist who comes his way. It's like Riley is a bad fanfiction's Mary Sue Self-Insert come to life, and is the reason why he is my most hated character in Arc-V. I hope that he suffers a crushing defeat, and maybe get turned into a card, because that's what he deserves. The only plus side is that at least this pitiful first duel brought Ally's cards to the real game. Besides that, I just wanna comfort poor Ally and tell her she'll win next time.
* Tropers/{{Awesomekid42}}: In episode 45, Sora and Kurosaki begin their rematch duel. This was something to be hyped for, being an opportunity to see new cards from both of them, and have a good follow up duel. What happens in it? After the two turns shown in episode 45, the writers skip to the final turn in episode 47 with Sora winning, with no other parts of the duel being shown. This is a major disappointment. We did get to see some new cards from both of them, but this not only came off as incredibly lazy, but a duel that many have been looking forward to was completely denied. To rub more salt in the wound, both Sora and Shun are panting in exhaustion before the final turn telling us that it must have been much more difficult for Shun than the last duel was.

''[[AC: Anime/YuGiOhVRAINS]]''
* Tropers/{{Arabian-Knight}}: Blue Angel losing to Spectre. It feels like a dishonor done to a fan favorite character. Especially because Spectre's cards don't exist in the real game (at least, not yet), and seem to be made specifically to defeat Blue Angel.
