History FanFic / TheInfiniteLoops

* AmbiguouslyHuman: Many Loopers, due to repeated species swaps, shapeshifting and other looping randomness, have been so many different things that ''they'' aren't even sure what they are anymore. Exacerbated in some cases due to these changes being permanent outside of Null Loops (i.e. absolutely Baseline loops where a Looper is back to their default form), leaving some to become an EldritchAbomination with a thin veneer of humanity.

** The ''VideoGame/FateGrandOrder'' loops can be found [[https://m.fanfiction.net/s/13938347/1/The-Grand-Order-Loops here]].

* AlternateRealityGame: In a sense. The 'Hub' universe is suppose to be ''our'' universe, and isn't looping because it was the only universe not damaged by what supposedly caused the loops in the first place (aside from ''[[Main/CoolAndUnusualPunishment Eiken]]'', of course). While rarely ever brought up, there ''is'' mention that loop compilers and writers are supposedly seers who are able to see the shenanigans the characters get up to in the loops and are compelled to write about it as part of Yggdrasil's system of backing up data.
** It's also possibly for loopers to loop into something called a 'near-Hub' loop for a brief time, which is essentially a copied, one-off loop version of our world where the Loops fan-fiction itself doesn't exist, to prevent Loopers accessing the main backups. Not many writers actually ''do'' anything with this outside of the characters talking to their original creators or taking items from the Hub loop, but it's there, technically making the loops this trope.

** An event known as The Crash involves the highest level of destruction happening to an entire branch, that is a universe and its directly related multiversal variants, of Yggdrasil. It has been completely and [[RetGone retroactively wiped from existence]]; loopers that once knew whatever branch it was simply ''do not'' anymore, even the Admins only ''suspect'' that the Anchor for that branch had an instrument of some kind.

** The Gods trying to repair Yggdrasil being referred to as 'Admins'. This was because, originally, the Admins from ''Anime/AhMyGoddess'' were the ones repairing the multiverse. As the loops continued to grow and more deities based on actual mythical deities began popping up, ''actual'' Admins from that particular anime started becoming rarer and rarer, to the point they almost never pop up at all.

* BeyondTheImpossible: Yggdrasil is like a computer and if loopers force it to do things that its not programmed for or doesn't have the capacity to perform, the result is an error. Errors mean more work for admins and [[AnythingButThat Eiken loops for loopers]].

** And of course, a lot of authors are not above sporking [[FandomSpecificPlot common fandom plots]] or clichés, be they {{Mary Sue}}s, {{Copy Cat Sue}}s, TrappedInTVLand variants, or common RonTheDeathEater targets. Pretty much if it's a common fandom plot element, it's been parodied or picked at in the loops at ''some'' point.

* The VideoGame/{{Xenoblade}} loops are located [[http://forums.spacebattles.com/threads/xenoloops-now-its-infinite-loops-time.313278/ here.]]

* ApocalypseHow: Actions that result in ''Eiken'' Loops or extremely messed-up Loops often fall somewhere in here. In addition, the Loops themselves are a last-ditch effort by the gods that run reality to stave off the absolute highest level of this, i.e. the complete annihilation and cessation of all reality throughout the infinite multiverses.

* BlackHoleSue: InUniverse, [[Literature/{{Twilight}} Leah]] [[LampshadeHanging complains]] how no matter ''what'' she or anyone else does, "Everything seems to revolve around those two idiots (Bella and Edward) and their relationship, whether it wants to or not." It's a fact that most loopers, even from said universe, [[TakeThat cannot stand Bella and Edward, and it's why those two are the most wildly hated two non-loopers both in and out of universe because of it.]] Regardless, it doesn't stop loopers from causing them hell every chance they get, no matter how much they eat up baselines they loop into.

* CoolAndUnusualPunishment: Loopers who manage to crash a Loop by pulling too many shenanigans (creating extra work for the admin responsible for it) get punishment loops in unpleasant settings, the most notorious being the [[AnythingButThat Eiken loops]]. The rare few that enjoy Eiken loops get sent to places that they personally hate instead.
* CosmicFlaw: Yggdrasil, the world tree, is actually a gigantic computer and each of its branches is a different reality, and it so happens that that computer has crashed; so badly that the gods - better known as Admins - are trying to fix it and the only way to buy time is to have people in the various settings repeat their lives over and over and over again. And yes, the system is susceptible to viruses.

* HatedByAll: All [=MLEs=] (Malicious Looping Entities) and many malicious non-loopers such as Umbridge. [[spoiler:Hence, when Gendo Ikari starts looping when it was thought he never would, he finds himself at the mercy of an entire ''multiverse'' that hates his guts. Most of the loopers have met his baseline self (due to ''Evangelion'' being one of the seven oldest looping universes), and most (if not all) of them are '''not''' happy to see him looping.]]

* ZeroPercentApprovalRating: All [=MLEs=] (Malicious Looping Entities) and many malicious non-loopers such as Umbridge. [[spoiler:Hence, when Gendo Ikari starts looping when it was thought he never would, he finds himself at the mercy of an entire ''multiverse'' that hates his guts.

* MesACrowd: Among the many powers loopers can learn like [[Manga/{{Naruto}} Shadow Clones]], the Misaka glitch can cause this as well, accidentally making an undetermined amount of same, ''awake'' loopers during a single loop. While it's not advised that they should get in into fights with their copies when this glitch occurs, since the duplicates end up merging back to the 'real' one once the loop ends and they get all their memories from it, naturally, for many loopers, ThereCanOnlyBeOne...

* GenderBender: According to [[MyLittlePonyFriendshipIsMagic Twilight]], this happens roughly two percent of the time. Some Loopers can have this a lot more often, however.

* WithGreatPowerComesGreatInsanity: This is a given. It's even explicitly stated by [[MyLittlePonyFriendshipIsMagic Twilight Sparkle:]]

** [[Anime/DeathNote Death Notes]] have been altered to where they can't work outside of pure baseline runs or their fused loop of origin, since even non-loopers or [=MLE=]s would be able to kill even the most powerful of Loopers and Anchors due to it being an even bigger StoryBreakerPower than what even the most powerful of loopers can posses. (And unlike the [[DepopulationBomb deplorable word]], Death Notes could be activated from ''anywhere'' in the universe they're currently in before the nerf was applied, are divine in nature instead of magical, making countering them difficult, can be used before the looper is even aware they're in they're in the same loop as one and could reasonably react to counter it, and allows the user to pick and choose who they want to kill. This would allow [=MLEs=] to remove any problematic loopers to their goal while keeping certain characters they need alive for whatever their goal may be.)

** While it's entirely possible for a looper to become [[TabletopGame/{{Exalted}} Exalted]], those powers are then generally removed by the admins at the first available opportunity, in part because if they hit a limit break, the character is likely to [[GodOfHumanOrigin ascend]] and become a very, ''very'' dangerous [=MLE=].

** We never really ''see'' the ''Eiken'' loops, only hear them referred to, probably because ''Eiken'' is actually quite dull once the novelty of the physiological implausibilities and incessant fanservice wear off... which is the entire point – for Loopers, boredom is actually the worst punishment of all.

** [[WesternAnimation/TheGrimAdventuresOfBillyAndMandy When the Grim Reaper]] is the only viable Anchor candidate for your universe, you know there's something seriously wrong up there. Granted, [[SubvertedTrope he's actually not that bad of a guy]], even in comparison to more "normal" looper settings. Doesn't stop Billy and Mandy from eventually becoming Loopers, though. Ironically, ''Billy'' is the one who became labeled the MLE of the two, due to being literally LethallyStupid, to the point where he regularly crashes Loops and kills Anchors ''on accident'', or making loopers crash the current loop to get away from the hell he accidentally made. A number of loopers start killing him on sight just to avoid any further madness.

** Artemis, who was among other things a goddess of wild animals, is in charge of the ''Franchise/JurassicPark'' and Series/PrehistoricPark Loops.

* ContinuityDrift: In universe, the loops can sometimes have certain details vary between them.

* CrapsackWorld: Not only are examples of these settings caught up in the loops, some realities are labeled as Quarantined either because they are filled with malicious malware and viruses, manifesting as a [[MindRape mind raping]] EldritchAbomination to Loopers, or because there are things in their baseline which are flat out dangerous to the multiverse as a whole. [[{{Manga/Uzumaki}} Uzumaki]] is an example of the former and [[Webcomic/{{Homestuck}} the Skaia protocol]] used to be an example of the latter.
** Also the Lovecraft Mythos, albeit due to a nonstandard cause:

** The ''Literature/{{Twilight}}'' universe isn't highly regarded by visiting Loopers. It almost drove its Anchor, Leah, to despair and madness, and Loopers forced to go there tend to raise hell or kill those responsible for the setting's condition.

* DarkerAndEdgier: And LighterAndSofter. Gets [[ZigZaggedTrope zig zagged]] pretty frequently. While generally light hearted, some writers will often write darker and more serious snips for several reasons, be it for character development reasons, plot reasons, or just because. Likewise, more serious in nature loop series will often have sillier snips that fall more in line with usual loops shenanigans. And some loops are, thanks to Yggdrasil's sickness, far more darker and worse off than the baseline of a given branch, such as when an Anchor's friends and family turn on them or the world was [[VillainWorld conquered by the villain]] before they woke up.

* TheDreaded: Malicious Looping Entities ([=MLEs=]) by and large, but while Kyubey, the Tick, and even Dio Brando are considered horrifying, even they pale compared to the [[LethallyStupid black hole of idiocy]] known simply as ''[[WesternAnimation/TheGrimAdventuresOfBillyAndMandy Billy]]''. Mandy, who was ''aiming'' to become TheDreaded, was slightly less than thrilled at being upstaged by her idiotic friend.

** Not that some of the Loopers are much better.

* ExpendableAlternateUniverse: Generally averted. Crashing a Loop is regarded as a Bad Thing, and even doing horrible things that'll 'reset' when a loop does is not smiled upon. In fact, having this viewpoint is a critical component of [[GoMadFromTheRevelation Sakura Syndrome.]]

*** ''WesternAnimation/TheRenAndStimpyShow'' was a looping world commissioned late in the game to act as a punishment when Eiken wasn't enough.
** More seriously, ascending past a certain power level can cause a universe to potentially [[RetGone cease to have ever existed]].

* GodIsFlawed: The Admins; they're even stronger than the Loopers, older as well, and generally just the same mentally as the Loopers are.

** Pretty much the only reason Ryuk ended up anchoring the ''Anime/DeathNote'' universe is because of this. Not only does being a Shinigami make him immune to [[ArtifactOfDoom Death Notes]] (so the Anchor doesn't randomly die and crash the Loop), he quite frankly doesn't give a crap about the vast majority of the people from his verse, making smaller room for MLE potential. (And considering he's one of the few people from the DN verse who ''isn't'' a raging psychopath...)

** [[WesternAnimation/TheGrimAdventuresOfBillyAndMandy When the Grim Reaper]] is the only viable Anchor candidate for your universe, you know there's something seriously wrong up there. Granted, [[SubvertedTrope he's actually not that bad of a guy]], even in comparison to more "normal" looper settings. [[spoiler: Doesn't stop Billy and Mandy from eventually becoming Loopers, though.

A number of loopers start killing him on sight just to avoid any further madness]].

* MultipleChoicePast: Those suffering under Dissociative Loop Identity Disorder experience this, much to their dismay as after a while, even ''they'' aren't sure who the 'real' them is. It's caused when a Looper has many different variants based on how many [[AlternateContinuity Alternate Continuities]] their loop's universe has, where they have different roles and personality in almost every one of them. The most extreme cases are [[Franchise/TeenageMutantNinjaTurtles April 'O Neil]] (who has no less than ''ten'' possible 'real' hers and personalities) and [[WesternAnimation/MyLittlePonyFriendshipIsMagic Lyra Heartstrings]], who has four based on common fandom interpretations of her due to her being a side character in baseline (though, unlike April, she's embraced her [[SplitPersonality split personalities]] and frequently [[TalkingToThemself talks to them in her mind when she has to make important decisions]]).

** Aphrodite, goddess of Beauty, gets roped into administrating the Eiken loops, mostly to keep up appearances. (Considering [[BrainlessBeauty what she's like]], most admins consider this to be a win/win: she's one of the very few who ''likes'' that branch.)

* ObstructiveBureaucrat: This is the main reason the ''Franchise/StarTrek'' Anchors never ''really'' act on their foreknowledge (to the point where the vast majority of visitors don't know ''who'' the Anchors are), as they'd have to explain themselves to their branch's Department of Temporal Investigations in ''every'' Loop. Since they cannot stomach the idea of literally endless paperwork, every ''Star Trek'' looper deliberately choose to be stealth loopers.

** Anyone's reaction to meeting an Malevolent Looping Entity.

* OmniscientDatabase: Yggdrasil, as per ''Manga/AhMyGoddess'' canon. Except right now it's on the fritz.

* TomatoInTheMirror: Those suffering from Chrysalis Syndrome (AKA: First awaking after a non-baseline run where they have a different role, and thus keeping their memories from that instead of their usual baseline) go through a brief bout of this. Thankfully, it's not as bad as [[MultipleChoicePast Dissassociative Loop Identity Disorder]] because after the first initial loop, they have a solid baseline to get used to, but they do have a hard time accepting it depending on what their role was. (''Especially'' if they're normally a villain, which usually results in MyGodWhatHaveIDone.)

** The Crash was a wham episode for every single Loop. An entire universe was wiped out, completely and utterly, damaging several other universes, and jumpstarting new Loopers in the process.

* WillfullyWeak: No Looper is allowed to ascend to the same level of godhood as the admins, as it will cause the destruction of their home loop. Experienced Loopers normally use a mixture of GuileHero, PowerLimiter, ManipulativeBastard, and [[HyperspaceArsenal the tools in their subspace pockets]] to avert VictoryIsBoring.

* YankTheDogsChain: Attempts to end the loops have happened way too many times, and it's [[FailureIsTheOnlyOption always resulted in a reset]]. The anchors have long since stopped caring.

** One Loop had Carmen steal [[Franchise/SlyCooper The Cooper Gang's]] jobs, forcing them to be Interpol agents chasing her. A later Loop had them [[LaserGuidedKarma turn the tables on her]].

* LetUsNeverSpeakOfThisAgain: Many Loopers run into common Variant Loops that they all agree to never mention again. Some examples include the ponies' [[Fanfic/TheConversionBureau Bureau Loops]], Marvel's ComicBook/{{Marville}} variants, and the Pokeverse's Fanfic/PokeWars worlds.

* LoopholeAbuse: [[VideoGame/FireEmblemAwakening Grima]] manages to bypass the "no villain looping" rule due to SharingABody with Robin, who is the anchor for that universe.
** [[spoiler: Anti-Villain Paradox from the Yu-Gi-Oh loops seems to have managed to avert this rule.]]

* LivingEmotionalCrutch: Stealth Looper [[spoiler:Ozpin]] from the ''WebAnimation/{{RWBY}}'' Loops considers other Loopers this for the Anchors. As they put it, "No one being could ever survive eternity alone." The Loopers give the Anchors companionship to keep their sanity and thus their lives intact.

* MultipleChoicePast: Those suffering under Dissassociative Loop Identity Disorder experience this, much to their dismay as after a while, even ''they'' aren't sure who the 'real' them is. It's caused when a Looper has many different variants based on how many [[AlternateContinuity Alternate Continuities]] their loops universe has, where they have different roles and personality in almost every one of them. The most extreme cases are [[Franchise/TeenageMutantNinjaTurtles April 'O Neil]] (who has no less than ''ten'' possible 'real' hers and personalities) and [[WesternAnimation/MyLittlePonyFriendshipIsMagic Lyra Heartstrings]], who has four based on common fandom interpretations of her. (Though, unlike April, she's embraced her [[SplitPersonality split personalities]] and frequently [[TalkingToThemself talks to them in her mind when she has to make important decisions.]])

** Bishamonten, god of righteous warriors and punisher of evildoers, runs the collective Gundam loops.
** Clio, the Muse of History and Zeus' daughter, coded the Assassin's Creed loops.
** Epona, Celtic goddess of horses and fertility, is in charge of the Legend of Zelda loops and, on at least one occasion, has looped in as Epona. She's also Sleipnir's girlfriend.
** Ganesha, god of learning and education, helms the terminally confusing, inconsistent and incomplete Attack on Titan loops.
** Hephaestus, god of technology, is responsible for the multitude of Mega Man Loops, as well as Ratchet and Clank and Thomas the Tank Engine.
** Hades, god of the underworld (the place where souls reside), being the admin for Manga/SoulEater, WesternAnimation/DannyPhantom and ''Manga/BlueExorcist''.
** Janus, a god of passageways, manages the Portal Loops. [[spoiler: Also, he became Admin for Disney / Kingdom Hearts loops, but eventually needed to have other Minor Gods help out to lift some of the burden.]]
** Loki, the Norse god of trickery, is the Admin for WesternAnimation/HowToTrainYourDragon.
** Maat, responsible for judging the deceased, manages the Ace Attorney Loops.
** Masakado, local deity of Tokyo, manages the Shin Megami Tensei and Persona Loops.
** Nut, a Egyptian goddess of the heavens (i.e. space), is in charge of the Star Wars and Star Trek Loops.

** Sleipnir, who is a horse, happens to be in charge of the My Little Pony Loops.
** Thor, who had a chariot pulled by two goats, is (partially) responsible for the Goat Simulator Loops.
** Zurvan, the one who got the Doctor Who universe Loops going, was a god of what else but time and space.
** Tu Di Gong, a Chinese god of wealth and and merit, handles Total Drama.

** [[Anime/DeathNote Death Notes]] have been altered to where they can't work outside of pure baseline runs or their fused loop of origin, since even non-loopers or [=MLE=]s would be able to kill even the most powerful of loopers and anchors due to it being an even bigger StoryBreakerPower than what even the most powerful of loopers can posses. (And unlike the [[DepopulationBomb deplorable word]], Death Notes could be activated from ''anywhere'' in the universe they're currently in before the nerf was applied, are divine in nature instead of magical, making countering them difficult, can be used before the looper is even aware they're in they're in the same loop as one and could reasonably react to counter it, and allows the user to pick and choose who they want to kill. This would allow [=MLEs=] to remove any problematic loopers to their goal while keeping certain characters they need alive for whatever their goal may be.)

** We never really ''see'' the Eiken loops, only hear them referred to, probably because Eiken is actually quite dull once the novelty of the physiological implausibilities and incessant fanservice wear off. (Which is the point – for Loopers, boredom is actually the worst punishment of all).

* ObstructiveBureaucrat: This is the main reason the ''Franchise/StarTrek'' Anchors never ''really'' act on their foreknowledge (to the point where visitors don't know ''who'' the Anchors are), as they'd have to explain themselves to the Department of Temporal Investigations in ''every'' Loop.

** [[TabletopGame/SentinelsOfTheMultiverse Absolute Zero]] seems to have one of these moments. During said loop he installed an [=MP3=] player and spekaers in his armor, then started to liberally play [[WesternAnimation/Frozen2013 "Let it Go"]] when he felt like it. He however failed to check to see who else was Awake, so Argent Adept recorded the whole thing and uses it to annoy Absolute Zero.
** [[WesternAnimation/MyLittlePonyFriendshipIsMagic Applejack]] will never live down the time she tried to make an alcoholic beverage out of potatoes (explanation: their name in French means 'apples of the earth', so she tried to make cider out of them) and ended up creating what has since been dubbed "potato acid", which blinded Twilight (who had to ascend to alicorn form to fix it), and set Discord on fire. This has been brought up several times since, with Applejack complaining about not being allowed to live it down.

* {{Railroading}}: Safe-Mode Servers, such as Eiken, railroad loopers onto the canon plot. On a personal level, Setsuna Syndrome is characterized by seeing the events of the baseline (or in some cases, a 'perfect timeline') as sacrosanct and attempting to railroad events to happen like they would in canon. This is usually because the sufferer believes that doing so will end the time loop.

** Loops based around other fanfiction universes also tend to pop up pretty frequently too. Notably, even a few characters from Fanfiction universes have ended up becoming loopers too. These include Fanfic/NobodyDies Rei and [[Fanfic/PastSins Nyx]].

** What happens if this happens to a Looper (at least in-universe) is explained in a Mega Man loop. It won't get rid of the Looper for good, but as Sonic explains it, getting hit with the Ultimate Annihilator (essentially a RetGone ''weapon'') tends to end the Loop really fast.

* StealthExpert: Every Star Trek Looper manages to keep themselves hidden incredibly well, to the extent that only two have been discovered by other Loopers so far, Captain Kirk and Captain Picard. The reason for this is because if the Department of Temporal Investigations found out, the Trek Loopers would be buried in paperwork.

** The fact that Fanfic/TheConversionBureau variants are often treated with by disdain from the [=FiM=] loopers, and the multiverse at large, can be see as a TakeThat to its setting.
** While not treated as AFateWorseThanDeath territory, they're often not particularly fond of pre-Gen IV MLP loops either.
** Literature/{{Twilight}} is often treated as a FateWorseThanDeath loop for a good portion of the Multiverse, its Anchor (Leah) included!
** Eiken loops, being used as the most common punishment loop, is in the same boat too.
** The Star Wars loopers aren't particularly fond of the more MerchandiseDriven spin-offs of their loops, the Christmas special being a very common target.

** The Crash, which happens when something went [[NoodleIncident horribly wrong]] in a fused Mega Man Loop, resulting in the total erasure of the unknown loop. It had knock-on effects through-out the other universes, even causing several new loopers to activate.
** Another one happens later on, this time because of a human-obsessed [[WesternAnimation/MyLittlePonyFriendshipIsMagic Lyra Heartstrings]], [[WesternAnimation/MyLittlePonyEquestriaGirls a magical portal]], and a poorly thought-out plan, which according to Twilight Sparkle prematurely ended at least three separate loops, and set the loops back by a few thousand years.
* TimeyWimeyBall: The loops hate this, resulting in the Series/DoctorWho universe being Read-Only for a long time. This is because causing a TemporalParadox while in a Loop causes it to crash, something a bit more severe than simple premature termination of a Loop.
