History NightmareFuel / FullmetalAlchemist

* Roy Mustang. Episode 53/54. What happens when Envy reveals he's the bastard who killed Hughes? Roy's facial expression immediately changes into '''the DeathGlare to end all {{Death Glare}}s'''. Not to mention his personality does a complete 180, [[UnstoppableRage acting like a demon of unfathomable fury and rage has possessed him to torture and kill Envy in the most brutal, cruel, and frightening ways imaginable]]. Not to mention that after Envy tries to get Mustang to hesitate by ''[[TooDumbToLive imitating Hughes]]'', Mustang's glare actually gets ''worse.'' Then comes a barrage of flames to Envy, making the whole scene as terrifying as watching [[Film/ReturnOfTheJedi The Emperor torture Luke Skywalker]] all over again.

* In episode 14, “Those Who Lurk Underground”, the chimera Martel, who has jumped into Al’s suit of armor body in order to control him, is stabbed to death by Bradley. Granted, it’s not Al’s true body, and presumably he doesn’t feel anything physically, but still—having someone die ‘’’while they’re literally inside of you’’’ is just straight up horrible (and all the more so when you remember that Al is just a young child, despite outward appearances).

* Shou Tucker himself. The very thought that a man could transmute his ''wife'' and later his ''four-year-old daughter'' and her dog Alexander into a chimera is just nauseating in all sorts of ways. From Nina's garbled speech, ''she wasn't even fully aware of what had happened''. Worse yet, remember, the chimera is half-dog. It's hard to tell how much of her understanding is Nina’s or Alexander’s. And then Scar shows up and {{Mercy Kill}}s her.

* Shou Tucker himself. The very thought that a man could transmute his ''wife'' and later his ''five-year-old daughter'' and her dog into a chimera is just nauseating in all sorts of ways. From Nina's garbled speech, ''she wasn't even fully aware of what had happened''. Worse yet, remember, the chimera is half-dog. It's hard to tell how much of her understanding is Nina, or her pet. And then Scar shows up and {{Mercy Kill}}s her.

* The... ''[[BalefulPolymorph thing]]''... which was created from Pride using the Gold-Toothed Doctor as 'raw materials' for the transmutation. Sure, he deserved it, but ''still''...

** The characters' reactions to the sight of this says all that needs to be said about it: they're horrified at the sight before them, the absolute extreme of the UncannyValley, and Alphonse says aloud that everything about this is completely and utterly '''''wrong'''''.
