When Flint kills Ruby in Bunnykill 4, Snowball proceeds to flip out in a manner that can only be described as Super Saiyan meets frenzied Mimiga. And in 5, Dust does Snowball one better after killing him under the influence of the Psycho Serum that Smoke had injected into him by completely devastating Smoke's army of mooks, wrecking his helicopter gunship as he tries to get away and then sending the bastard right through its rotor blades. Flippy of Happy Tree Friends goes into this whenever anyone does something that reminds him of the war he fought in. Subverted in "Remains To Be Seen", "Class Act", "Autopsy Turvy", and "By The Seat Of Your Pants" when he is killed while in his flipped-out state. In "A Vicious Cycle" his rampage continues even after his death. In If the Emperor Had a Text-to-Speech Device, the Emperor is prone to do this when he hears about something particularly wrath-inspiring about the Empire, such as the Inquisition, senseless waste of resources or Traitor Legions. As he's immobile, this mostly manifests by him spawning warp storms. Millie in Helluva Boss is a very competent Cute But Psycho Professional Killer at normal times. Threaten her husband Moxxie and she goes into deadly Mama Bear mode. But (as seen in season 2 episode 3) try to get her out of the way and force Moxxie to marry a really annoying guy who's both her and his ex... words don't begin to describe it, and eighteen or so mafia goons trying to stop her are little more than something to vent her emotions on. Things she does during this battle include biting someone's heart out, kicking a bullet out of mid-air, and pulling someone's skull out of their head. Mystery Skulls Animated: When Lewis stops his rampage and seems to be connecting with Vivi, Arthur (understandably) takes the opportunity to grab Vivi and run, Lewis and Vivi lose their moment to reconcile, breaking Lewis' heart (literally). As a result, Lewis becomes enraged and cuts loose with his power. SMG4: In the episode "Princess Capturing Simulator", after Bowser cheats, Mario gets so angry that he teleports to where Bowser is and shoots him once for all. Fazbear and Friends (ZAMination): Opila Bird reacts this way when Scottie forgets the last egg and starts chasing him with a horrible rage that makes Scottie run away screaming, still trying to find the last egg.
