Sure, the Infinite Loops are all fun and games. Until the fun stops and the screaming starts.
This page is for directly stated horrors. For more indirect ones, see The Infinite Loops
The Setting in General
- Sakura Syndrome. Imagine a nigh-unstoppable being with knowledge spanning several universes, who doesn't care about anyone else and just does whatever they want, because it's not like anything will stick when the universe resets.
- And its counterpart, Setsuna Syndrome, though on a much lesser scale. It's when a Looper is determined to make sure everything follows a "predestined" path. Apparently some of them can get very violent about making sure this happens.
- The Loop That Never Was, and the implications of its destruction. It's gone, completely and utterly, from time and space, forever. No-one, not even the Admins can remember it, and Yggdrasil can't restore it. And it's implied other universes have gone the same way before.
- Eiken is this in-universe for pretty much every Looper, due to how it's set up as a crash-recovery loop. No pocket and no loop-powers. The mind crushing boredom is absolute AGONY for Loopers, and will avoid it at all costs.
- Except for Naoki, who can be a normal human, not an Unwitting Pawn of Lucifer and the Great Will, and doesn't have to hurt his friends. Indeed, he considers the place paradise.
- Billy is also unaffected by Eiken, and in fact quite enjoys it. With the exception of Naoki, actually enjoying Eiken is a sign of a diseased mind and a potential MLE.
- Most Rv B loopers enjoy Eiken, with Sarge regularly marrying 'Sensei Sensei'.
- As funny as they can be, the idea of the Elevator Saga snips (being trapped in an elevator for extended periods of time as time and space bend in strange ways around you) is absolutely terrifying, even without claustrophobia. That is not even getting into the Mind Screw and reality warping that results.
- Any Malicious Looping Entities. Some are merely insane and bring that along with them, causing irreparable mental damage to even the most stable Loopers. Others actively seek to ascend to the same status as the Admins — which necessitates the destruction of their own branch.
Loops With Their Own Folders
- The attempts by Hephaestus to get the universe Looping can get incredibly unsettling, but worst of all is the one when Roll is made the Anchor. Her brother goes off to fight Wily, same as usual, and then disappears without a trace. Some time later, Wily reappears, and reveals he's killed Rock and put his remains on display.
- Reverend Dark, a devout robot supporter who shows up in some Loops. From Roll's point of view, even Xander Payne would be better than him. And then there's his habit of having his brain placed in a robot body.
- The thing that apparently possesses Dr. Light in one of Blues' failed Loops. We never learn exactly what it is, but it's pretty clear whatever it is, it's not supposed to exist. And by the time Blues realises he's in danger, it's too late. It's practically a relief when the Loop fails seconds later, otherwise god only knows what would've been done to him.
- It counts as in-universe nightmare fuel, since Blues is still traumatised by it for a long time after.
- And then, come chapter 11, it returns, and gets inside Blues.
- The Crash, already disturbing in its effects and implications, gets expanded on in the last failed Loop. It starts off dark and goes from there. Dr. Wily doesn't show up, but someone's producing various robots labelled "Model-(designation)", ultimately reaching Models X and Z, all but outright stated to be X and Zero themselves, who abduct the Anchor from the Loop That Never Was. After defeating Model V (also known as Vile), Rock, Roll and Blues are knocked out and abducted. And then they meet the mastermind behind everything so far: Dr. Wily, Sigma, Weil, and Dr. Albert, all apparently merged into one being, with the thing that Blues encounter beforehand at the wheel. And it knows about the Loops, and it wants to spread. And now that it has the Loopers, it's going to do just that, with a creepy-ass machine of some king that all four Anchors happen to be attached to. But something goes hideously wrong, and the last thing Blues can recall before everything goes dark is reality itself screaming. And then? Crash.
- Waltz. Sweet mother of mercy, Waltz. Imagine a dangerous, unstable version of Roll. Now give her the ability to copy her enemies' weapons just by being near them. Then give her the ability to Loop. She's completely insane and ruthless, willing to kill anyone she sees, and near-impossible to keep down.
- Even worse is the hint that she's not completely crazy, but that this fact just makes her angrier.
- Waltz states, in chapter/page 39 that she can hear her Unawake self, quite a decent person for a change, in the back of her head, asking who she is and pleading for her to stop. All that, because Roll grabbed her hand.
- Naoki's breakdown. Already ground up by countless Conceptions, losing his friends every single time, forever unable to change anything, alone with a demonic Split Personality, his Pixie, Black Frost, and sometimes the Fiends to talk to (who really don't seem very healthy company), then placed in the Sugar Bowl that is MLP after a particularly horrifying Bureau Loop (which apparently, had very little, if any, effect, other than making him innately mistrust Equestria, just to underscore how brutal and violent he'd become in the end), confronted with the fact the ponies, the monsters who wrought such sheer madness, live in a relatively quiet, peaceful Loop where villains can be defeated - and redeemed - with The Power of Friendship, and infected with the Delphinus Parasite? He explodes with sheer, utter insane wrath. Eons after eons of Sanity Slippage... breaking in a single instant.
- The rationale behind the responsible entity, Naoki's Shadow. Normal Shadows want the original to die so they can take their place. This thing is a Loop-aware Shadow - an aberration that understands the idea behind the Loops, and has adapted. Since it can't kill Naoki, it seeks to have him labeled as a MLE by specifically targeting Equestria, one of the most influential Loops, ensuring every Looper's response when confronted with him will be violence, meaning no one will help him, ever. And it's smarter and more ruthless than normal Shadows, capable of outright memory editing and sensory tampering. While it later gets stopped, by that time it has nearly driven Naoki to outright attempt Ascension and collapse the entire timeline just to make it STOP.
- The Conception is made agonizingly worse. As one of the most corrupted Loops, so far, it has not demonstrated a single Variant, and only a minuscule amount of Fused Loops. The bitter knowledge there are better worlds beyond while stuck in a vicious Bleak Death World where all other humans are dragged into murderous insanity with no way to change it makes it look Naoki's rampage was more of a when than an if issue.
- And yet, Naoki is painfully aware he's better off than Aleph.
- The White talk to the recently-looping Sovereign, and taking advantage of his lack of understanding of what's going on, talk him into unleashing a destructive blast by simultaneously destroying the Catalyst and the Yamato Perpetual Reactor. While it would allow Sovereign and the Reapers to Ascend to Yggdrasil's level, it would also completely wipe out the Mass Effect timeline. Sovereign, terrified, is fully aware this is pure insanity, but he's so crazy and desperate, it overwhelms his reservations and starts following the White's orders.
- And apparently, the White managed to talk a bit with Naoki before being defeated. His quiet breakdown at the victory party implies they managed to get some good barbs in, indirectly and eventually pushing him into the outright crash he suffered at Equestria.
- Flynn and Isabeau are constantly trying to get their friends Walter and Jonathan to loop... only to fail each and every time because their friends somehow die. Every. Single. Time.
- The Junkyard. Anyone who loops there is infected with Atma, which immedietely forces them into a cannibalistic rampage. It is noted that most people who loop there need therapy in MLP afterwards.
- First of all, any fused loop with the Junkyard leads in a societal collapse.
- There was one time when Lady from Devil May Cry looped in there. Her breakdown was so bad that the local loopers had to get Naoki Kashima to help comfort her.
- There was also that fused loop with Persona 4. Yu - who was replacing Serph - was suddenly consumed by his Persona almost immediately among awakening and when he came to the first thing he found out was that the leader of an opposing tribe had been replaced by his uncle. A character from the brightest Persona game having DDS as their Formative Loop...
- Normally, the Doctor's Loops are generally light and fluffy (the normal horrors of that universe aside), but then comes a horrific variant of the Reality Bomb. It's not a Reality Bomb, and it's builders aren't Daleks. They're ponies. It's a conversions bomb, designed to turn every living thing in every universe into a mindless pony. All topped off with a ponified version of Davros' speech... given by Twilight Sparkle.
- The explanation for why the ponies took living beings from the twenty seven worlds as well: They needed a control group.
- The Doctor describing one of his failed attempts to save Donna, by making her a Fact like Jack Harkness. It didn't work, and just meant Donna kept coming back to life and dying, over and over and over again, until all the Doctor could do was crash the Loop to avoid hearing her screams.
- Darth Charybdis, AKA Sith Jar Jar. Imagine Jar Jar Binks, but one who breaths fire, speaks in a demonic Voice of the Legion style a la the Son, and has deadly mastery of a four bladed lightsaber. The scariest part is, this variant loop has happened more than once. Any Jar Jar you meet could very well by Darth Charybdis, playing the fool before he guts and sears you alive.
- The destruction of the Puella Magi Madoka Magica universe, by Kyubey's manipulations. Even worse is that there were at least some Loopers inside it at the time, and Madoka herself had genuinely thought that she was doing the right thing. And worst of all is that Kyubey not only survives, but escapes into the rest of the Loops, free to try his plan again on every other world.
- The fact that Kid Miracleman could beat down Loopers like Edward and Alphonse, and that they could only beat him through trickery and playing at his childish feelings of wanting to prove himself. If they didn't then it was likely that Kid would have gone on his canonical rampage through London right then and there...
- Яeverse The Loops - An error when activating the Cardfight! Vanguard loop that allowed the forces of Link Joker to start trying to take over the multiverse, and affect currently-running loops. It was bad enough that activating Cardfight! Vanguard (a quarantined loop!) was the best possible solution. Even after it was dealt with, the fallout ended up traumatizing the Admin of the Transformers loops, Pandora, when her loopers considered genocide to be the best option available to them.
- Hurricane Billy. Imagine something so ineffably stupid, so thoroughly dumb that their stupidity is contagious. Once a Billy began looping, he crashed multiple safe loops, pissed off Caboose, succeeded in killing Han Solo, Anakin Skywalker and Twilight Sparkle ''twice'', terrified two experienced Amalaverse Anchors by replacing every single person in the Loop with copies of himself, drove Kyubey to drink in public and is solely responsible for Gendo Ikari looping, amongst other crimes. A unanimous vote decreed that Billy would be labeled an MLE.
- When the Fire Emblem loops start destabilizing, the admins start looking for the reason. It's Morgan. Their solution? Rewrite the entire baseline, so that Morgan ceases to be. And the worst part is, they didn't even look for a solution beyond this.
- Thankfully, it has ceased to be canon to the mainstream Fire Emblem Loops, but it has become one of Robin's recurring nightmares.
- The implication that the Anchors of Attack on Titan 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 Ace Attorney and Five Nights at Freddy's, the Purple Man gives an utterly creepy Motive Rant, with lights flickering as he speaks with a smile on his face, right before he jumpscares the courthouse in Springtrap.
- While they downplay it...Five Nights at Freddy's is looping. It can show up in crossovers EVERYWHERE.
- 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. And quite a few have met death at their hands.
- For a short time Roxanne became this for Blue and the Admins, after a bad argument with Godzilla Roxy became noticably twitchy and less rational. This was shrugged off for a time till a loop with only Her, Blue and Tim awake on the Island happened and Roxy when crazy rampaging through half the park killing innocent people and children. Even worse is that while she was torturing the I-Rex to death Blue honestly couldn't tell the difference between the Rex and the Big One from Jurassic Park.
On the Admin side of things Roxy's mental and spiritual stability was tanking (Due to the fact Godzilla helped shape her personality and mind) and if they couldn't find a way to stabilize her soon they would find out what happens to a Looper once their ability to loop was gone.
- Aisha once killed the Black Circle Wizards by filling them with Morphix until they exploded.
- Jurassic Park can prove to be this if it's the Telltale Game version of the Loop. AKA the version of cannon with the Psychotic Troodons with a paralyzing venom that drives you insane and immobile....So that they can rip open your chest cavity and lay their eggs in you leaving you to be eaten alive by the soon to hatch babies....ALL of the native Loopers hate the Troodons, possibly even more then the Indominus.
- The Evronians. A nigh-unstoppable race of Emotion Eaters numbering in the billions, going around space on a Planet Spaceship and 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 (one of the most dangerous Loopers around) mentioned in passing that they once drained him.
- The SCP Foundation 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.
- SCP-682 itself ended up facing Naoki Kashima... and 682 laughed him off. Note, Naoki was molded to kill YHVH, so 682 laughing him off makes one wonder what kind of threats 682 laughs off as well.
- The Koprulu Sector is looping. While Raynor is the Anchor, Sarah Kerrigan is a looper. And by extension, the Zerg as a whole.
- The Xenogears loops are considered hell loops because the baseline is brutally unforgiving and soul-crushing, and prone to null loops. Which means if the local anchor is not present, the plot cannot be derailed.
