History SailorEarth / AnimeAndManga

** Back before all the Warlords of the Sea were revealed, it was common for some OC villains to be this. This was back when Mihawk and Crocodile were the only ones revealed to be one and actually be made as characters, where Doflamingo and Kuma, while revealed, had little screen time. Other popular positions were Admirals and other high-ranking Marines. Since there were two vacancies among the Warlords [[spoiler:before the system was abolished entirely]] and an unknown number of former Warlords, and one Admiral with no information known other than his/her code name ([[spoiler:at least until his proper introduction at the end of the Wano arc, [[GreenThumb powers]] and [[PoliticallyIncorrectVillain mindset]] included), there remains plenty of room for such characters.

** A good rival for this kind of character would be a mysterious man with a CoolMask who pilots a red Mobile Suit with three times more advanced specs than the standard model. Why not? [[CharClone It's common in canon!]]

** It also lends itself to {{crossover}} fanfiction well, either with original characters or [[PossessionSue reworking a character from another franchise]], usually sci-fi and picking a planet or even just a country or area from the other franchise's lore. This approach grants you a Sailor [[Series/DoctorWho Gallifrey]], Sailor [[Franchise/StarWars Naboo]], or Sailor [[Literature/Dune Arrakis]].

** Want to make a new angel? There are literally dozens of names in biblical canon that the series doesn't use. Azrael and Samael, the angels of death, are particularly common. Sometimes, fans will opt to just add "-iel" to the end of an English word. Case in point: Clockiel, the fan name for the Seventh Angel in Rebuild.

** Although the Guardians' uniforms are shown to be vastly different around the galaxy with the Sailor collar being the only always-present component (compare the Starlights and the Solar System Guardians), many OC creators tend to stick with the Sol Guardian uniform formula despite there being little to no evidence of Guardians elsewhere having similar uniforms; it's probably because it's the easiest to work with. And if FanWorks involve making a Sailor Earth possible, many find themselves pressed for creative ways to take Mamoru and his alter ego Tuxedo Mask out of commission so his Sailor Crystal can be passed to someone else; some others simply make her his sister and/or have their character embody a different aspect of Earth than what Mamoru does.

** Some people like to create new Celestial Spirits for Lucy (or, rarely, for a fan character) to use. As there are literally dozens of unused constellations to choose from, this leaves open a lot of potential. However, instead of being Silver Keys like all non-Zodiac constellations are ''supposed'' to be, these sometimes get hit with super-powerful White Keys or Dark Keys. Common constellations for these super keys include Pegasus, Canis Major, and Draco.

* ''Manga/MyHeroAcademia'' has an extremely fertile setting for [=OCs=], given that it's a world in which 80% of the human population is born with superpowers, ranging from [[WhatKindOfLamePowerIsHeartAnyway near useless]] to [[StoryBreakerPower completely overpowered]], to everything in between, and the main cast are the students of resident SuperheroSchool U.A. Academy; said OC will usually join U.A. as a NewTransferStudent, and will be placed in Class 1-A, presumably filling the vacant spot [[TheScrappy Mineta]] left after the author had him kicked out of U.A.

** SpinOffspring series ''Manga/{{Boruto}}'' made way for a new type of Sailor Earth: next-generation characters. Like a character and they apparently have no kids yet? Make some for them! Most of the Konoha 12 have at least one child, however that leaves room for characters like Kiba and Tenten who don't. There are also OC siblings for the existing characters (such as Sarada receiving a, usually pink-haired, brother or Shikadai gaining a sister).

** Any hypothetical Sailor Guardian, but especially the obviously missing "Sailor Earth". (This role is technically filled by Usagi's boyfriend and future husband Mamoru Chiba.[[note]]Mamoru/Endymion has the Golden Crystal, the Sailor Crystal of Earth; however the rule is that only women can be Sailor Guardians, so this makes his Tuxedo Mask form the closest to a canonical Sailor Earth.[[/note]]) The manga's creator later admits that none of the later Guardians were actually planned out before they appeared, since the series was initially intended to only feature the few girls to follow the FiveManBand rule; once the manga's fourth arc made canon the existence of ''asteroid'' Guardians with Sailors Ceres, Pallas, Vesta, and Juno, the door was flung wide open. As a result, any astronomical object tends to get a Guardian,[[note]]though it's not likely anyone is going to make a Sailor 99942 Apophis or a Sailor 47 Ursae Majoris b[[/note]] and this was going on ''well'' before Pluto was demoted from planetary status. Stars are extremely common targets for fan Guardians, the most prominent continuing to be creating a Sailor Sun (aka Sailor Solaris if you're being technical). Following Pluto's demotion and Ceres's promotion in 2006, Guardians representing the other three dwarf planets, especially Sailor Eris, as well as several of the likely dwarf planets became popular subjects. Not to mention Guardians for planets in our solar system that have been proposed to exist but are generally accepted as fictitious, like Planet X/Nemesis (the supposed tenth planet, which is canonically home to the Black Moon Clan) or Vulcan (Mercury's supposed twin on the other side of the sun). Guardians representing the solar system's other moons are also reasonably popular thanks to the title character, especially since the anime implies that the Sailor Starlights are also lunar Guardians.

** This trope also applies to villains, as the series employed largely gem or mineral based theme names to each villain group, with a slight tweak for themes. Thus, most fanfic villain groups find themselves named after whatever collection of gems or minerals the author thinks is menacing enough. Double points if that gem or mineral ends with "-ite" (common examples being "Quartzite" or "Pyrite") and triple points if they're a missing King (often mislabeled "General") from the first series.

* ''LightNovel/AriaTheScarletAmmo'' focuses on a paramilitary academy where students are taught to use guns, stunt drive, collect information. It's very easy to create a student for that.

* ''LightNovel/{{Overlord|2012}}'' is about a player of a futuristic full immersion MMORPG (called a DMMO-RPG) ending up in a fantasy world unrelated to his game, but with the appearance and skills of his in-game avatar. As an MMO "so popular that whenever the word "DMMO-RPG" was mentioned, listeners would immediately think of [it]," the game would doubtlessly have millions of players. Given the only (known) requirement for being transported to the New World is that the player be logged in when the servers were shut down for the last time, any of these potential millions of players could be a new OC.
