This is simply what you think is the (not some of the, the) best example of any trope (an objective trope, not subjective, since this already is subjective). The "Crowning Example" if you will.
There could be several reasons you think an example is the best.
You think it's the best in terms of illustrating the trope.
You think it's the most well done.
It's your favorite play in that trope.
You just really like the source material.
Oh, several things before you list examples:
Each troper gets one example per trope, no more.
Don't go "no, this is," or phrases like that. This is about our own personal favorites.
NBC's continued refusal to allow U.S viewers to access a legit livestream of Olympic opening ceremonies "so our producers can provide context" (translation: they think the incessant, inane blathering of the Today Show hosts is helping. ~ Nlpnt
Freiza from Dragon Ball Z. He had the longest fight in the entire series with Goku. He comes back to life in the 12th movie and is killed by Gohan in one hit. How can it POSSIBLY BE WORSE THAN THAT? ~ Ericho
Apollo Justice'sKristoph Gavin. For an idea of this, he gets so mad that as he raises his fist to bang on the witness stand in frustration, the dishes that had previously fallen on the ground behind him rise up into the air and fall down as he slams his fist on the witness stand. Please note: this man has no magic powers. ~Darkurai
Same game series, different perp: Damon Gant. How many villains do you know that have a breakdown speech where they stand there laughing and clapping maniacally for an entire minute? ~ Willy Four Eyes
Same series (notice a trend?), different villain: Manfred von Karma. After he spends hours grinning smugly at you, the guy snaps like a twig on slow-motion and bangs his head against the wall after screaming at the top of his lungs. ~ vicnog
Really, pretty much any villain in this series. Redd White with his strange headdesking thing, Dahlia Hawthorne in 3-1 AND 3-5. The Tiger's seizure-inducing breakdown, and Daryan Cresend and his hair. Going everywhere.
Gotta give it to Matt Engarde clawing his face out, although all of the breakdowns in the series are great. Considering it's kind of a once an episode type thing, the whole SERIES deserves to be the Most Triumphant Example, although this troper is tempted by Light Yagami and Marlo Stanfield. ~rickdakirb
Dukat in Star Trek: Deep Space Nine to the point of getting plastic surgery to make him look like a Bajoran and seducing the head of the Bajoran religion. One might say his breakdown turned him into a Magnificent Bastard. ~ EvaLilith
Kratos. Non-stop. The games never try to hide from you the fact that the guy is a monster, and after the events of the first game you can cross off the Hero in Anti-Hero in regards to him. ~ The Jerk with No Name, Dracosummoner, todbot1
The Nazis from Das Boot. No other story I know of can so consistently make you root for them and feel for them before slapping yourself once more and reminding yourself of who they are. That ending alone seals the deal. -Ziggy Zag
Doctor Steel. Many, since he's a musical supervillain. But "Dr. Steel" is probably the crowner. "I have become the man with a plan / With an army of toys and a mechanical band / Ruling the world making everything real / I’m Dr. Steel, Dr. Steel!" ~ Jonny B
Terumi Yuuki. Yes, he may look like a magnificent Troll in plain eyes, but dig in deep and you'll see he pretty much out-sues all entries above. ~ Chris X
Unquestionably Uchiha Madara. Overpowered when he was nothing more than an offhand reference to a character thought long dead, his eventual appearance in the manga has become a stream of ever more nauseating sue-ness until he reaches the stage where he can basically do whatever the hell he wants to anything he wants any time he wants. None of the rules or precendents of the setting apply to him, he summons up New Powers as the Plot Demands practically without thinking, No Sells absolutely everything, he's a God-Mode Sue so absurd he makes the most amateurish efforts by the most uncreative fanfiction writers look weak by comparison. And he's not even a remotely well written villain either, which just rubs salt into the wound. ~ Arcane Azmadi
Americans. Most of them are not loud, boorish, fat, lazy, uncultured, stupid, etc. Shocking, isn't it. ~ Gundamforce
Straw Feminists. So vocal and so triumphant that even many tropers on this very wiki seem to believe that feminism is synonymous with misandry. ~ Gfrequency
Conspiracy theorists in general. You'll be surprised to find out that most conspiracy theories actually had less adherents that it seems. ~ CounterBlitzkrieg
Avatar-bashers, even now, well over a year after the film's release. For the want of good things said about the film on the internet by anyone anywhere (or even new jokes made about the same few perceived flaws by the haters), it is extremely difficult to consider the film's good reputation anything but mythical. Will it never end?! - ZuulMF
You haven't seen walls of text until you've read the (Ultimate) Warrior's comic book. Seriously...every page of that damn thing is like that. I think this, more than anything, is what qualifies the man as beyond batshit insane. ~ Willy Four Eyes
Thor's Hammer/The Mana Cannon from Tales of Symphonia and Tales of Phantasia. A Wave Motion Gun so big that if you power it with the world's mana - which is what it was designed for - it kills the World Tree producing that mana. The only time we know of that it was ever safely fired was at a lower capacity, and powered by the Summon Spirits instead of drawing from the local mana pool directly. ~ Sylvia Viridian
Commander Kubrik Chenkov, whose favored tactic is to mire the enemy in melee combat with his troops... and then call in an artillery strike on them. His special rule, "Send In the Next Wave!", literally allows him to call in unlimited conscripts. After the last batch has been utterly obliterated of course. ~ Petro
The Doctor: No, Amy, you're not here. And you haven't been here for a long, long time...
When you're playing a game that requires everyone to have a secret position (Mafia, the Battlestar Galactica board game, etc.), and you are sure that one person isn't an antagonist...but then comes their turn, and they say a line that just makes you realize that the protagonists' mission is about to be severely boned. ~ King of the Mime Swing
Seconded! That was one of the best psychotic ramblings I've ever heard, and I've heard a lot of psychotic rambling. "Do you know who I am? I'm the man who's gonna burn your house down! WITH THE LEMONS!" ~Takwin
Thirded! "I'm going to get my engineers to invent a COMBUSTIBLE LEMON, that BURNS YOUR HOUSE DOWN!" ~ Zfish9
Thirded; Are we allowed to change our votes when something more batshit insane comes up? - The Albino Primid
Fourthed, and I believe you can, so long as you delete your previous vote. ~ Zfish9
Fifthed. And it's interesting how this bizarre mess is a Weird Japanese Thing in disguise as a Weird American Thing. It manages to exponentially sum up all the weirdness of both universes, so much that the only reason Season 2 was not yet made is because the sheer accumulated density of its weirdness would create a black hole on Earth and cause The End of the World as We Know It. ~ Electric Boogaloo
Twilight: Jacob realizes Renesmee is his soulmate mere minutes after she is born. He will be like her uncle and protector until she is seven but physically seventeen at which point they will commence the baby making. -Limelightqueen
Marvin the Paranoid Android.Let me count the ways. First, he's a Flawed Prototype that's chronically depressed and has constant severe pain down his left diodes. That's how he starts. Over the course of the series, thanks to a great deal of time travel and an even greater deal of taking The Slow Path, he lives to be 37 times older than the Universe itself. Since he has a brain the size of a planet, he remembers all of it. Almost every part of his body has been replaced, often with inferior or even useless parts, save for his aching left diodes. He's so miserable that other artificial intelligences are Driven to Suicide just by being connected to him. The only time that he's ever felt even slightly happy is right before his death, when he reads God's Final Message ("We apologize for the inconvenience"). ~ mysterykcad
One Piece... just One Piece. If the author one day decides to add romances to all the sheer emotions in this series it will surely make its universe implode into a gigantic Black Hole Ham. ~ Spatial Temporal
Heath Ledger as The Joker. It was the oddest choice, almost nobody (including myself) believed in it, and it turned out to be one of the best instances of a "so crazy it just might work" idea actually working in the history of filmmaking. ~ Ziggy Zag
