History NightmareFuel / FateStayNight

* Bad End 20, "Hazy": Caster turns Shirou into a living wand for projection magic and Rin ends up mercy-killing him.

*** Even the implication that Shirou has to kill both Ilya and Rin makes this ending even worse, for both girls, but possibly more horrible for Rin:

** Bad End 30 "Stone Coffin": On Day 9, if Shirou decides to close his eyes and attack Rider, he finds out that this ''doesn't work'' -- he gets petrified by looking at Rider's eyes in his imagination. [[TakenForGranite His stone body falls]] and [[LiterallyShatteredLives breaks into pieces]].

* The Makiri parasitic worms. Don't think about how, if you've had the comparative good fortune to be born male, they'll simply kill and eat you as that is exactly what happened to Kariya at the end of LightNovel/FateZero . And ''especially'' don't think about how, if you're unlucky enough to be female, they'll eat you alive (ovaries first) while essentially raping you at the same time. Even more, don't think about how poor Sakura has had to spend practically every night for the last ''eleven years'' stuck in a room full of these horrible things.... And this is JUST the backstory! These worms are ''PENISES with'' ''MoreTeethThanTheOsmondFamily''.

** While doing this is very much an insane and suicidal move, ''not'' doing this gets you Bad End 2, "Girl Rhapsody". In this Bad End, Shirou gets the hell away from Berserker, only to lose Rin to the rampaging beast, head to the church, and then get severely wounded by Berserker, whereas Illya decides to torture him in place of his father Kiritsugu.

* Caster has three Bad Ends alone, two of which involve the use of Rule Breaker. Rule Breaker acts to destroy and nullify any kind of Magecraft, and in particular allows Caster to sever the contract between Servant and Master, essentially allowing Caster to steal control of a Servant from said Master, which Caster uses to turn Saber against Shirou. The other Bad End involves Caster cutting off Shirou's arm for his Command Spells after transporting him into her clutches with a transference spell.

* The final confrontation with Illya starts off with her kidnapping Shirou, knocking him out with her HypnoticEyes. When he wakes up, he finds he's tied to a chair in Illya's castle and she tells Shirou to "be mine." While she is sitting on his lap enthusiastically, [[NoYay with the implication she's going to rape him]], and in fact there was a sex scene planned that was thankfully dropped. The player has the option of saying no or giving an insincere "yes", while Shirou is scarred out of his wits, knowing that Illya is likely to kill him if she doesn't like his answer. Saying no continues the route, where Illya gets jealous and leaves to kill Rin and Saber. If Shirou says "yes" just to buy time to weasel his way out of danger, Illya's reaction is cute at first, [[WomanScorned until she realizes that Shirou was lying]]. [[OhCrap Shirou learns the hard way that question was a magic where agreeing to Illya's request gave her control over him]], and despite not meaning his answer, she got enough control over him to force him to agree to be hers and actually mean it. After this she has his soul taken from his body and is implied to have been used as either Illya's boytoy or a disposable pawn to win the Grail War with.
