"NOOOO! YOU VILE SCUM! YOU LIE!! YOU ARE ALL CORRUPTED! CHAOS HAS PLANTED ITS SEED IN YOUR MINDS! YOU ARE ALL HERETICS! HEEEEREEETIIICS!!!"
— Inquisitor Fyodor, after finding out about The God-Emperor of Mankind's ability to speak again.
- During the Trial To End All Days, AJ of AJCO was confident enough in her victory that she went so far as to insult both the prosecutor and the judge. However, when it became clear that she was going to be pronounced guilty, she revealed that she had planted nukes beneath the courtroom, fled the courts and activated the world-breaking device that then launched them all into a new world. Breaking down with style.
- From Death Note: The Abridged Series (kpts4tv):
- In Dr. Horrible's Sing-Along Blog, the main character is shown as a Technical Pacifist and Ineffectual Sympathetic Villain who states that killing isn't his style. However once his Jerk Jock archnemesis Captain Hammer states that he's going to steal the girl of his dreams just to torture him, he then goes into a Villain Song where he swears to kill him. This is followed in rapid succession by Captain Hammer's own breakdown when he is made to feel pain for the first time in his life (it's hard to call it a Heroic BSOD when he's shown to be just as evil as the protagonist), and a second, deeper one from Dr. Horrible when his victory coincides with the death of his Love Interest.
- Freeza in Dragon Ball Z Abridged goes through this a few times in season 2. Most notably in episode 25.
Oh, I'm sorry. I'm usually far more composed. I'm just a little bit ABSOLUTELY LIVID.
Freeza: You think you're better than me?! Lord Freeza?! *beat* WELL YOU'RE NOT! I own you! I own your planet! I own this planet! In fact - FUCK THIS PLANET!.Goku: Wait, I zoned out there for a second, what?
- He becomes even more so with Goku, not because of his resilience, but his absolute stupidity gets on his nerves.
- His final one is when he learns that Trunks, this mysterious warrior that showed up out of nowhere and made mincemeat out of his men, was a Super Saiyan. Enough was enough.
Freeza: Kill. Murder! Destroy! EXTERMINATE! EXTERMINATE!
- Metal Cooler has this in Cooler 2 not just from Goku and Vegeta overpowering the Big Gete Star's systems after they were thought to have been drained dry, but for Goku and the gang constantly pointing out he's ripping off everything Frieza did.
- Cell in his second form is turned from a Smug Snake into throwing a temper tantrum at being beaten around by Vegeta. It's only until he plays to Vegeta's ego that he recovers quite well.
- Perfect Cell flips his lid when Kenshiro nails him with the Hokuto Hyakuretsu Ken and makes him explode.
- The Evil Overlord List refers to this a few times, most famously #24: "I will maintain a realistic assessment of my strengths and weaknesses. Even though this takes some of the fun out of the job, at least I will never utter the line "No, This Cannot Be! I AM INVINCIBLE!!!" (After that, death is usually instantaneous.)"
- In If the Emperor Had a Text-to-Speech Device, Karamazov breaks down once Custodes surround him, screaming that he's the only one left pure, that everyone else is a heretic and that the text-to-speech device is a lie. He gets over it quickly enough, but loses it ten times as hard when he finds out he's exiled to the Warp with an addled Kaldor Draigo, with what could only be subtitled as [Inquisitorial Angry].
- Dio in JoJo's Bizarre Adventure Abridged has a notable, albeit brief, one when he realizes Jotaro can out-Time Stop him.
No... No... No, no, no, no, NO! MOTHERFUCKER!!! NO!! NO! NO! NO! BULLSHIT!! BULLSHIT!! BULLSHIT!! Okay, okay, okay. Calm down, Dio. Calm down. Calm down.
- Terrence in KateModern — goes from smug, quietly intimidating badass in series 1 to raving, giggling psychopath by the end of "Precious Blood".
- The Shadow and Rupert van Helden have also suffered this by The Last Work.
- In Lost Boys Of The Cascades, Barry suffers a villainous breakdown after his attempt to frame the Klamath Indians for murdering Jennie, Troy, and Dylan falls apart due to Troy surviving and telling the truth.
- In The Spoony Experiment review of Street Fighter 2010, Doctor Insano suffers a breakdown after failing to create the ultimate being (instead producing a cute pink blob thing). He begins crying about how his science never works and nobody loves him before his new "son" cheers him up.
- Survival of the Fittest: Maxwell Lombardi has an epic one (complete with laughter!) in his final fight with Naoko Raidon which he does not survive.
"You... I have to admit, you're not the first guy on this island to seriously piss me off, but if there was a competition going on you'd of just won first fucking prize."
- In To Boldly Flee, Mechakara trembles and screams in incoherent rage when he finds out Terl tricked him into working for him.
Jan De Bont: It's so ingenious! It's so inspired! Hey, I don't care if it was laughed off of The Disney Afternoon! I'M THE ADULT! I'M THE ADULT! I WRITE ADULT THINGS!! (points to the original summary) That...that's stupid! Stupid psychological issues! (spits on and then defecates on it) YES! I'M THE ADULT! I WRITE ADULT THINGS!! YOU'RE DUMB! YOUR DUMB! THIS IS THE REAL STUFF!!! THIS IS THE REAL SCARY STUFF!! ROBERT WISE IS STUPID!!! HE DOESN'T KNOW WHAT HE'S DOING!!! I DON'T CARE IF HE MADE SOME OF THE MOST LIKABLE MOVIES OF ALL TIME!! HE'S DUMB!!! HE'S A DOODOOHEAD!!! IF YOU TOOK POO AND ADDED EVEN MORE POO, THAT'D BE ROBERT WISE!!! HE'S DUMB!!! HE SO DUMB YOU HAVE NO IDEA AT AAAAAAALLLLL!!! LOVE ME!!!! LOVE ME AND DON'T LOVE THAT!!!! THIS IS STUPID!!! lOVE ME!!!! MELOVEMELOVEMELOVEMELOVEME!!!! I'M THE GENIUS!!! I'M THE GENIUS!!! I'M THE GROUNDBREAKING GENIUS!!! ALALA!!! ALALALALALA!!!
- And while we're on the subject of the Nostalgia Critic, in his review of The Haunting (1999) he impersonates Jan De Bont as an ignorant idiot who considers himself and his remake superior to Robert Wise and his original. At the end though, Jan breaks down trying to get people to like his childish and hammy edits to the original ending:
- In Tribe Twelve The Observer has a glorious one (complete with an incoherent roar that has the words 'SHUT THE FUCK UP!) when Firebrand prevents him from abducting Noah.
- When Jotaro is about beat Steely Dan down in Vaguely Recalling JoJo, he becomes very desperate and reenacts Light Yagami's breakdown. It gets worse after Captain Tenille refuses to help Steely Dan.
- The fourth Season of Noob shows the toll that the Mistaken for Badass situation between Dark Avenger and Sparadrap has taken on Dark Avenger, causing him to outright quit the game over the situation by the Season's third episode.
- The killer in Season Two of Where the Bears Are has one when Reggie takes the call from the police and discovers that his alibi has been faked.
- Red vs. Blue:
- C.T. or rather, her Insurrectionist lover, who took her identity after she died, goes from calm and collected secret keeper, to a screaming maniac when Tucker shows up to rescue Sarge, Grif and Caboose. Keep in mind that he kept his cool while facing down both Tex and Carolina.
- In the penultimate episode of Season 12, Felix has been doing what he usually does in his fight against Tucker: Evil Gloating with the usual sociopathic cheer to his demeanor, yammering on in ways that describe his & his partner's plans (which the heroes already know at this point). Ever since his Evil All Along reveal mid-season, he's been cocky and insulting and horribly cruel and just won't shut up. But then, Tucker reveals that Church is inside his armor, using Tucker's helmet-cam to record the entire spiel, and then he sends it to play at the planet Chorus' capital, exposing Felix & Locus' plot to the Federal Army and New Republic that they've been manipulating for so long, bringing the war - which F & L have spent years carefully orchestrating - to a screeching halt. His response? A long stretch of stunned silence, followed by:
"You... You're DEAD!!"
- He goes very, very close to this when he retrieves the key from General Doyle… only to realise that Doyle is the only one who can activate it. When Sharkface admits to not being able to inform him of this Felix immediately threatens to kill him, almost like a child throwing a tantrum.
- He suffers a much longer one before and during his final battle with the Reds and Blues. He screams at Locus when Locus states that they've lost, yells childish insults at the Reds and Blues, is humiliated in his fight against them, and, when Locus pulls a Heel–Face Turn, Felix pathetically tries to get him back on his side.
- From the same episode, the partner in question goes through a much more subtle one. Locus spends his battle against Washington cloaked and taking opportunistic shots at him. But then Washington gives a speech that deconstructs Locus' Consummate Professional image, culminating in him calling Locus a coward. This pisses off Locus enough that he abandons tactics and goes for a straightforward beatdown of Washington. When the scene cuts to him again, he's seen hesitant for the first time in the series, only telling his mooks to follow protocol.
- This Gmod video has a non-verbal example where Painis Cupcake imitation Ass Pancakes becomes visibly unhinged over his inability to bonk Derpy Sonic's skull.
- Those Murderous, Insane and Not Remotely Funny Nazis in The Anglo/American – Nazi War have a pretty spectacular one when D-Day comes around and the Western Allies begin pushing them out of occupied Europe. That is, they begin systematically destroying landmarks and other cultural artifacts, along with salting the earth and poisoning the wells, just generally doing everything in their power to ensure that there's no such thing as a Europe after their defeat. Including a televised destruction of Paris which is so thorough that the post-war capital of France has to be moved to Lyon.
- Similarly, in the Alternate History/Nineteen Eighty-Four fanfic America's Stepbrother, America's Enemy V2.0, the Inner Party of Oceania become increasingly high-strung as the reality of their imminent defeat becomes more apparent to them and their ability to use Doublethink to cope becomes compromised.
- Epic Rap Battles of History:
- Adolf Hitler loses what little sanity he had in his final battle with Vader, killing Boba Fett and delivering a final verse composed of nonsensical insults that don't even sort of rhyme.
- Hannibal Lecter has a far more mild one when Jack the Ripper points out that he's a fictional character, but regains his composure by his next verse.
- When Ruby Rose boards the Atlesian cruiser that Roman Torchwick hijacked, he gets very frustrated as this is the third time she's meddled in his fun, but he doesn't go into full breakdown until she's able to take Neo out of the picture and she vows to win the day. He quickly resorts to beating her with his cane, ranting and raving about how her Heroic Spirit doesn't have a place in this cold and unfeeling world, that if she's going to play the part of the hero, then she should just roll over and die already and that he'll keep on going by lying, cheating, stealing and surviving. He's then promptly eaten by a Griffin Grimm.
- In Volume 4, Tyrian (who's already Ax-Crazy), has one when Ruby amputates his scorpion stinger with Crescent Rose, screaming in agony and angrily calling her a bitch. Fortunately, he manages to recover enough to make a retreat and convinces himself that Salem will forgive him for failing his mission. When Salem quietly tells Tyrian that he has disappointed her, this is enough to reduce him to a sobbing wreck, and attracts the attention of a Beowulf. However, he bats it away with his broken tail and pounces on it, still sobbing, and begins angrily carving it up with his wrist-blades, his sobbing turning into mad laughter. This completely unnerves Cinder, who previously enjoyed watching the carnage of the Fall of Beacon taking place.
- In Worm, Emma Barnes is Taylor's biggest tormentor, smugly torturing her for the first couple of arcs. THEN she learns that her punching bag (who she thought "weak") was in fact a powerful super villain and could have wiped her out plenty of times since January. After that she simply shuts down and stammers. Sophia Hess, Taylor's OTHER tormentor, goes completely apeshit and kicks the TV in frustration
