History NightmareFuel / TheInfiniteLoops

** Goetia, mentioned further down in this list, always responds to Billy's appearance by teleporting into Chaldea the second he shows up, killing him and them immediately destroying the planet and crushing the loop while claiming that "destroying this timeline is a mercy."

* The Wiki/SCPFoundation is Looping. That alone should be enough for panic, as many of the things that come from that place are enough to make even a hardened Looper shudder.

* The implication that the Anchors of ''Manga/AttackOnTitan'' [[spoiler:are starting to succumb to Sakura Syndrome. Three Anchors, almost soul-bound from their devotion to each other, succumbing to Sakura Syndrome is very, ''very'' bad]].
* During a cross Loop between ''VisualNovel/AceAttorney'' and ''VideoGame/FiveNightsAtFreddys'', the Purple Man gives an utterly creepy MotiveRant, with lights flickering as he speaks with a [[FauxAffablyEvil smile]] on his face, [[spoiler:right before he jumpscares the courthouse in Springtrap]].
** [[spoiler:And then he suffers an [[IronicDeath ironic]] CruelAndUnusualDeath.]]

** And yes, the Anchor is the security guard, making it so that the Fazbear Crew, when you Loop into their restaurant, can be their old, homicidal selves without any forewarning. [[spoiler:And quite a few have met death at their hands.]]
*** [[spoiler:During the above ''VisualNovel/AceAttorney'' snip, it was hinted that The Puppet was looping through a BlinkAndYouMissIt moment. If you casually read through it, it doesn't seem all that important, but actually analyzing it reveals the implications.]]

* [[ComicBook/PaperinikNewAdventures The Evronians]]. A nigh-unstoppable race of {{Emotion Eater}}s numbering in the billions, going around space on a PlanetSpaceship and [[spoiler:making a new one out of a planet every time their numbers become too great on one of the already existing ones]], going around space to turn every sentient into an emotionless slave and armed with weapons that do that in one shot. That's their basic description from their series, but the Loops turned it up to eleven when DIO Brando (an MLE) mentioned in passing that they once drained ''him''.

* Rottytops' Awakening ends up taking an extremely dark turn. Her, Bolo, and Sky are in Shantae's mind and find an area of the Mermaid Factory they haven't seen before. Upon entering, however, they quickly discover [[spoiler:it's a brutal slaughterhouse. Both mermaid and human alike are forcibly moved into various machines to kill them in Techno Baron's cruel scheme]]. It proves to be so horrifying that Bolo and Sky can no longer go on.
** What makes it worse is that this is Shantae's memory of the place. Meaning that, most likely, she was [[spoiler:unable to save a lot of those people]]. Bolo even points this out to Rottytops when he bails out with Sky.
