When you have a CrisisCrossover or a MassiveMultiplayerCrossover, you'll need something in order to motivate the heroes into action. While having the {{Big Bad}}s of the series [[VillainTeamUp team]] [[LegionOfDoom up]] can work, sometimes you want an even BiggerBad. One that requires a such a massive team up of heroism.

And then, why stop there? Why not go the full way and make a new Hero for this crossover? That way you can have a central conflict for the entire story. Plus, since you'll have a character tied to this story instead of the differing canons of the other series, you'll be able to have more character development for the main character all in all.

The Bigger Bad variety is somewhat more common than the new Hero variety. Crossovers with new Heroes, however, have a tendency to become a series in their own right, a SpinOff that just happens to have crossover origins.

Oddly enough, ''rare'' in FanFic, likely due to the fear of them becoming {{Mary Sue}}s -- but see OriginalCharacter.

!!Examples:

[[foldercontrol]]

[[folder:Anime & Manga]]
* Fai, Kurogane, and Fei Wang Reed are the only new main characters in ''Manga/TsubasaReservoirChronicle'', the rest being AlternateUniverse versions of characters from other Creator/{{CLAMP}} works, or from XXXHolic, a sister manga by all intents and purposes, being the stories simultaneous ([[TimeyWimeyBall as much as the setting allows]]) and deeply intertwined.
* Ayumi Sakagami, the first movie-only active ''heroic'' Pretty Cure, in ''PrettyCureAllStars New Stage''.
** The ''Anime/YesPrecure5'' movie and ''Anime/HeartcatchPrecure'' movie both had original Cures, but the ones from ''Yes!'' were evil and the one in ''Heartcatch'' was just to set up a bit of backstory.
[[/folder]]

[[folder:Comic Books]]
* A well known BiggerBad example is the Anti-Monitor from DC's ''ComicBook/CrisisOnInfiniteEarths''. There were some new heroes as well--Pariah, Harbinger, the Monitor, Alex Luthor, Superboy-Prime, Lady Quark, and Doctor Light--but, with the exception of Doctor Light, they faded quickly after the event ended, only brought up when the writer wished to remind the readers of ''Crisis''. Or in the case of Superboy-Prime, to make a FaceHeelTurn and become a recurring BigBad in his own right.
** Similiar with 90's Bigger Bads - DC's [[OurWorldsAtWar Imperiex]] and Marvel's {{Onslaught}}.
* The ''[[http://en.wikipedia.org/wiki/DC_vs._Marvel DC vs. Marvel/Marvel vs. DC]]'' crossover had a new character named [[http://en.wikipedia.org/wiki/Access_%28comics%29 Access]]. As he's co-owned by the two companies, he isn't used very often.
* Another villainous Creator/MarvelComics example is The Beyonder, from ''ComicBook/SecretWars'' and ''ComicBook/SecretWarsII''.
* Lampshaded in Marvel's anthology ''Wha... huh?'''s ''Identity Crisis'' parody - Identity Girl says she was created just because of that one.
* Neron of DC's ''ComicBook/UnderworldUnleashed''. And the new hero is -- Trickster. Yes, the reform of a longstanding villain. On one hand, outwitting a devil is probably the best stunt he could have pulled of; on the other hand, he doesn't want to go somewhere warm after he dies, after pulling that off. And Neron, despite being an obvious plot device to beef up lack-lustre villains, has since made several appearances.
* In ComicBook/FinalCrisis by DC, the hero is Nix Uotan, a [[BroughtDownToNormal depowered]] [[PhysicalGod Monitor]].
[[/folder]]

[[folder:Fanfiction]]
* Aileen, Emperor Vakudos, Princess Lotora, Field Marshal Lackey, the Trashtors, General Doom, Dr. Beesano, Minion King, Tad With Lemon, [[MonsterHigh Draculaura's]] cousin, Fredward Skullen and more from FanFic/Hottie3TheBestFanFicInTheWorld.
* Kamen Rider Aka from [[http://alaxr274.deviantart.com/gallery/33810717# Super Milestone Wars]], he's the ''Franchise/KamenRider'' equivalent of [=AkaRed=] from ''Series/GogoSentaiBoukenger vs. Franchise/SuperSentai'' and ''Series/KaizokuSentaiGokaiger''. There's also Ultraman Aka, the ''Franchise/UltraSeries'' equivalent.
** The Autobot, Go-onimus.
** Becca and Danya, natives of the AKindOfMagic universe.
** The SpacePirate, Kasaku Sagi.
* General Hand, The Biggest Bad, Crushinator, Ominion, the Voidspace Army {{Mooks}} and Captain Tovasco da Bolokia from [[http://alaxr274.deviantart.com/gallery/36864527 Super Milestone Wars 2]]
** Princess Cecilia, Matt Keene AKA Captain Wii, Space Sheriff Aka, Watchman and Diendman who are the good guys
** OhWhite and Thaddeus C. Magnum AKA Decademan
** King Dyce, General Reppir and the Terlaemen.
** Don Tyrano, General Insecta, Fishtor & the Mechanoids (the bad guys) and Go-Tron (the good guy) in [[http://fav.me/d5f2u52 Super Milestone Wars: Year One]]
** Kamen Rider Erin in [[http://fav.me/d5fkhe3 Super Milestone Wars: Birthday Fic]]
** Super Great Leader, Machine Dopant and the Beeswax-Bots in [[http://fav.me/d5kqh6t Supetastic 6: Year Two]]
* The main character, Kit, from ''Fanfic/ASmallCrime'' fits into this.
* ''FanFic/TheCaptainOfTheVirtualConsole'' has Gancena and Selene, heroes, and the Thoughtless, who serve as villains.
* Rizki Al-Ibrahim, Endah Heinz (German-Indonesian student at PCA,) and Dominic Harrison from ''FanFic/{{Spongebob 2019}}''.
[[/folder]]

[[folder:Film]]
* The trope is OlderThanTheyThink, being featured in countless Godfrey Ho films (as highlighted on WebVideo/TheCinemaSnob) where incomplete or unreleased films would have additional plots and characters included with many featuring ninjas.
* Walter from ''Film/TheMuppets'' is a Muppet made for this movie. He is an interesting case for this trope as he was created for a single franchise (albeit jumping the Muppet Show continuity to the silver screen) rather than a crossover.
* Franchise/{{Godzilla}}, Film/{{Mothra}}, and Film/{{Rodan}} all originally appeared by themselves in their own separate Creator/{{Toho}} films. The former two would fight in the {{Crossover}} film ''Film/MothraVsGodzilla'', but when Toho decided to bring all three together in ''Film/GhidorahTheThreeHeadedMonster'', they were pitted against a new monster, King Ghidorah. This would lead to Toho's later {{Kaiju}} movies all more or less existing in the same universe.
[[/folder]]

[[folder:Literature]]
* Jason and Theatre/{{Medea}} from ''The {{Argonautica}}'' by Apollonius of Rhodes, which makes this OlderThanFeudalism. New character, Jason, leads a team of {{Crossover}} characters from across GreekMythology, yet in the end needs to be bailed out by another new character, Medea.
* Dante and Beatrice from the DivineComedy. A SelfInsert of the author meets the souls of [[HistoricalDomainCharacter historical people]] and [[PublicDomainCharacter fictional characters]] and eventually meets his UnrequitedLove.
* Roger Rabbit interacted with various comic strip characters in the novel ''WhoCensoredRogerRabbit'', which loosely inspired a [[Film/WhoFramedRogerRabbit film]].
[[/folder]]

[[folder:Live Action TV]]
* The lead Rider of ''Series/KamenRiderDecade'' is this. He's the original character that serves to cross over elements of the nine series before him, partially by being able to [[MegaManning make use of all their powers]]. His primary enemy, Narutaki, brings random enemies from the crossover elements to combat him. Diend, the second original Rider, serves as a rival who is less concerned with fighting Decade and more with [[{{Kaitou}} stealing]] and {{troll}}ing, but has the ability to send clones of crossover heroes ''or'' villains into battle for him. [[spoiler:The major enemy group Dai-Shocker later appears, which is basically one or two people who got the smart idea to have all previous enemy groups in the ''Franchise/KamenRider'' series stop fooling around and join forces.]]
** The GrandFinale [[TheMovie Movie]] is a bit more open about this: [[spoiler:Wataru Kurenai, the original universe ''Series/KamenRiderKiva'', tells the cast that Decade exists solely to be whatever the Rider worlds need him to be: hero or villain, savior or destroyer. He has no home and no story of his own, and therefore after he presses the ResetButton through SuicideByCop, there's supposedly no way to bring him back.]]
** Ayakashi Rakider Chinomanako Diend Form is this in Kamen Rider Decade's IntercontinuityCrossover with Series/SamuraiSentaiShinkenger. A monster of Shinkenger's world with powers stolen from Kamen Rider Diend, with the Diend Driver in its possession.
** Bonus point. When BandaiNamco revived ''The Great Battle'' crossover franchise with ''[[http://compati.channel.or.jp/fullblast/ The Great Battle Full Blast]]'', they don't even bother with creating new originals. They simply have Decade travel to the worlds of Franchise/{{Gundam}} and ''Franchise/UltraSeries''.
** The ''Franchise/KamenRider'' franchise's ''Movie Wars'' films, which bring together the current and previous Rider casts, tend to make use of these. The most unusual examples come from ''Film/KamenRiderXKamenRiderWizardAndFourzeMovieWarUltimatum'', which introduces modernized versions of several Creator/ShotaroIshinomori characters including Inazuman (as Series/KamenRiderFourze's student), Series/BishoujoKamenPoitrine (as [[spoiler:the Donut shop owner's "inner self"]] from ''Series/KamenRiderWizard''), and the Akumaizer 3 (the film's {{Big Bad}}s).
* Another toku crossover example is ''Series/GoGoSentaiBoukenger vs. Franchise/SuperSentai'''s [=AkaRed=]. He carries with him the powers of all the previous Red Rangers, and demonstrates as such by turning into [[Series/HyakujuuSentaiGaoranger GaoRed]] and [[Series/MahouSentaiMagiranger MagiRed]], as well as summoning weapons from other heroes.
** All six rangers in ''Series/KaizokuSentaiGokaiger'' can become any other Super Sentai hero. An enemy named Basco can summon them similar to how Diend did. As the extra cherry on top, [=AkaRed=] returns in a limited capacity, having served as TheMentor for Gokai Red.
* ''Film/KaizokuSentaiGokaigerVsSpaceSheriffGavanTheMovie'' has Gavan Bootleg. A robot built by Zangyack prison chief Ashrada with the combined technologies of the Space Police and the Zangyack empire. A pirated version of Gavan's Space Sheriff combat suit.
[[/folder]]

[[folder:Theatre]]
* ''Theatre/TwiceCharmed'' gives Lady Tremaine a Wicked Fairy Godfather who helps her plan revenge on Cinderella.
[[/folder]]

[[folder:Video Games]]
* TropeNamer and [[TropeCodifier probably the example that stands out the most in fiction]], [[LoadsAndLoadsOfCharacters due to sheer numbers]], are the various characters that Banpresto made for their ''VideoGame/SuperRobotWars'' series, as well as other crossover games (''The Great Battle'' and ''VideoGame/AnotherCenturysEpisode'', for example). Each game (excluding the first game and ''VideoGame/SuperRobotWarsCompact'') since ''VideoGame/SuperRobotWars2'' has added in new original heroes and villains, known as "[[FanNickname Banpresto Orginals]]", whose stories tend to link together the various licensed series in the game. The originals gained such a fandom that Banpresto made a SpinOff series consisting of nothing ''but'' their original characters, called ''VideoGame/SuperRobotWarsOriginalGeneration''. This was convenient, as the lack of licensing issues made it possible to finally bring the series to international audiences for the first time.
** The Original Generation games decidedly goes recursive, as a number of original characters were created ''just for'' these games.
** And now the ''VideoGame/SuperRobotWarsOriginalGeneration'' characters (At least Ryusei, Kyouske, and Masaki) have shown up in ''Another Century's Episode R'', where they ''aren't'' treated as originals. Banpresto has found a way to make it go full circle.
** Technically, the first Original Generation game was ''VideoGame/SuperRobotWarsGaiden'', which ''[[UrExample predates]]'' ''VideoGame/SuperRobotWarsOriginalGeneration'' by eight years. Unfortunately, its rather racy, risque dialogue sadly made this a NoExportForYou, though with a NintendoDS VideoGameRemake recently released, it might get a second chance.
** A NintendoDS ActionRPG, ''[[EndlessFrontier Super Robot Wars OG Saga: Endless Frontier]]'', stars AlternateUniverse versions of ''VideoGame/SuperRobotWars'' originals...along with the ''VideoGame/NamcoXCapcom'' originals mentioned below and KOS-MOS from ''VideoGame/{{Xenosaga}}''. Crazy, isn't it? The latter three are characters created by Monolith Soft, a co-developer with Banpresto for the game.
** They also have a tendancy to create new mechs and upgrades for already existing series. Among these are [[HadesProjectZeorymer Great Zeorymer]], [[{{Dancougar}} Final Dancougar]], and {{Mazinkaiser}} (the only one to become a CanonImmigrant).
** In fact the [[spoiler: Devil Gundam]]'s third TrueFinalBoss form is an original design for ''VideoGame/ShinSuperRobotWars''.
* In ''VideoGame/KingdomHearts'', you have Sora and his friends to make the Heroes. There are a few other side characters, and then the Bigger Bads: the various incarnations of Xehanort, Organization XIII, and of course in general, TheHeartless.
* ''VideoGame/TheKingOfFighters'' started as a MassiveMultiplayerCrossover with a handful of original characters, but has slowly evolved to the point that the originals nearly outnumber the crossover characters. To the point that what most fans complain about is not that the ''VideoGame/FatalFury'' cast have been downplayed in what used to be their tournament, but that one original character (Ash Crimson) has stolen the spotlight from ''another'' original (Kyo Kusanagi).
** Kyo Kusanagi actually had the spotlight stolen from him years earlier in KOF '99, with K'Dash, who in turn got it stolen by Ash Crimson It seems that every major story arc has a different protagonist, though Ash Crimson is definitely a VillainProtagonist, as well as rather effeminate, which would explain his unpopularity. [[spoiler: Until it was revealed that Ash was always on the side of the heroes, but had a very risky plan that ''relied on him pretending to be a VillainProtagonist'' and on ultimately ''causing his own death''. [[AlasPoorScrappy A good part of the fandom forgave him]].]]
*** The 3D Maximum Impact Series take this further by having different protagonists, Alba and Soiree Meira.
* ''VideoGame/NeoGeoBattleColiseum'' introduced two protagonists named Yuki and Ai, as well as an antagonist named Goodman. The [[TheKingOfFighters Orochi]] clone Mizuchi may also count.
* Most of [[CapcomVsWhatever the Capcom vs. series]] avoided this trope, except for:
** The Japanese version of ''VideoGame/MarvelSuperHeroesVsStreetFighter'' which had Norimaro, an InkSuitActor version of comedian Noritake Kinashi.
*** And in the same game, Cyber-Akuma, [[ExactlyWhatItSaysOnTheTin a cyborg version of Akuma]].
*** Not to mention Shadow, Metal Zangief, and Sunburned Sakura. ''Marvel vs. Capcom'' also had Shadow Lady and Lilith-style Morrigan.
** ''VideoGame/MarvelVsCapcom2'', where we got Ruby Heart, Amingo, Son-Son's granddaughter (also named Son-Son), and the boss Abyss.
** ''VideoGame/CapcomVsSNK2MarkOfTheMillennium'' with Shin Akuma (as in "God Akuma", not "True Akuma") and God Rugal. These were slight twists on existing characters (Shin Akuma and Omega Rugal), but could only exist as part of the crossover, since their existence involves Rugal absorbing the Dark Hadou or forcing his Orochi power into Akuma.
** ''VideoGame/SNKVsCapcomSVCChaos'' introduced Serious Mr. Karate and Violent Ken. The latter is based on the brainwashed Ken from ''The Animated Movie''.
** ''VideoGame/NamcoXCapcom'', starring Reiji Arisu and Xiaomu, as well as Reiji's arch-nemesis Saya, all tied together by dimension-hopping shenanigans that gave an excuse for all the game settings (ranging from ''VideoGame/GhostsNGoblins'' to ''StreetFighter'' to ''[[SoulSeries Soulcalibur]]'' to ''VideoGame/{{Xenosaga}}'' and even more) to be stitched together without too much scarring.
** ''VideoGame/CrossEdge'' hosts a whole slew of new characters that are not from any of the games of the five companies that "Cross" it, including lead characters Kannagi Yuuto/York Neely and Aiba Mikoto/Miko Aiba. There's also Toya/Troy, Anesha, Judas, Lazarus, Augustine, Raizen, Vivi, Eruma/Mimi, and Iruma/Cece, who all seem to be part of a greater plot of gathering different "Souls" from different worlds, thus explaining why you see characters from ''VideoGame/{{Darkstalkers}}'', ''ArTonelico'', the ''AtelierSeries'', ''VideoGame/SpectralSouls'', and ''Franchise/{{Disgaea}}''.
** Ingrid from ''Capcom Fighting Jam'', although she was eventually added into the {{PSP}} version of ''VideoGame/StreetFighterAlpha 3''. She was supposed to debut in the canceled 3D fighting game ''Capcom Fighting All-Stars'' with two other characters: D.D. and Rook.
** Shin from ''Street Fighter Online: Mouse Generation'' is the only character in the game who isn't from a prior Capcom game or another license.
** ''VideoGame/ProjectXZone'', SpiritualSuccessor to ''VideoGame/NamcoXCapcom'', features Kogoro Tenzai and Mii Kouryuji, as well as the originals from the latter game and a couple originals from ''VideoGame/SuperRobotWars'' and the ''EndlessFrontier'' spinoff.
* The ''VideoGame/SuperSmashBros'' series had a few; Master Hand and Crazy Hand, most of the bosses and the Fighting Polygons/Wire Frames/Alloys. ''Brawl'' brought in the all-original Subspace Army with its leader [[spoiler: Tabuu]]. Notably, most of the ''playable'' characters are still entirely crossovers. (Although some, like Mr. Game & Watch, does not exist in the games. He is a CompositeCharacter of all the various games.)
** Also of note, Master Hand crossed over into the Kirby Games and gives Kirby [[MythologyGag his Smash Bros. Move set when copied]].
** The Subspace Emissary also brought us the Ancient Minister, [[spoiler:who's actually a subversion. He's really [[NintendoEntertainmentSystem R.O.B.]]]]
* ''[[Franchise/TalesSeries Tales]]'' has the crossover series ''VideoGame/TalesOfTheWorld: Narikiri Dungeon''. The first game, on the GameBoyColor, had Mel and Dio, an [[MoeMoe entirely too cute]] matched set of silver-haired chibis with the ability to dress up as classes or monsters. When the series made the jump to the [[GameBoyAdvance GBA]], the new protagonists were given the ability to assume generic classes... or to go the whole way and become ''the other characters'' they were fighting alongside. These also included villains, spirits, and cameos like [[TaikoNoTatsujin Wada Don]] and Mr. Driller. Oddly, Pac-Man has not been a costume yet.
** The first one was not a crossover, it was a sequel to ''VideoGame/TalesOfPhantasia'' (and the title was even Tales of Phantasia: Narikiri Dungeon). The crossover began with Narikiri Dungeon 2, and was when the ''TalesOfTheWorld'' title started being used.
** And with the ''VideoGame/TalesOfTheWorld: Radiant Mythology'' series, the three Kanonnos and the three flying creatures (Mormo, Paneer, and Rockspring), among other original characters.
* ''VideoGame/MarvelNemesisRiseOfTheImperfects'' has half the cast as originals, the title Imperfects, who were also to become {{Canon Immigrant}}s. They didn't work out so well.
* ''VideoGame/MortalKombatVsDCUniverse'' has Dark Khan, a Bigger Bad who could only be created due to the crossover, being the result of {{Darkseid}} and Shao Kahn being struck down by {{Superman}} and Raiden respectively as they were going to escape into dimensional portals while the universes were seperate. All this happening at ''the exact same spot in time and space'', thus merging them ''and'' the two universes.
* ''Dengeki Gakuen RPG: Cross of Venus'' has a rare case of an unnamed original protagonist (and his (named) classmate), tying the various light novel series taken from the Dengeki magazine (including ''ShakuganNoShana, LightNovel/BludgeoningAngelDokurochan, LightNovel/{{Toradora}}, ''LightNovel/KinosJourney'', ToAruMajutsuNoIndex'' and ''NogizakaHarukaNoHimitsu'' among others) by forming a rag-tag party with their heroines in order to battle the BigBad's CanonDefilement.
* [[TheDragon Ruru]], and [[BigBad Nowel]] from ''MagicalBattleArena'', a doujin 3D battle game featuring the {{Magical Girl}}s and female mages from ''MagicalGirlLyricalNanoha'', ''Manga/CardcaptorSakura'', ''{{Slayers}}'', and ''MahoujinGuruGuru''. Kirara And Sarara are somewhere in between, coming from ''Magical Girl Kirara And Sarara'', an H-game that's related to this.
* The ''NicktoonsUnite'' series has the Wise Old Crab as a rare case of a ''supporting'' original character (all of the playable characters are crossovers) and the Mawgu and Globulous Maximus as Big Bads (the other villains in the series are crossovers).
* Takumi and Haruna of the Shin'i Organization and villainess Kuu in ''BattleMoonWars''.
* The DS version of ''[[VideoGame/MarioAndSonicAtTheOlympicGames Mario and Sonic at the Olympic Winter Games]]'' has the Snow Spirits as a rare case of ''MacGuffin'' original characters. No such things are present in the Wii version.
* The upcoming ''.hack'' game ''.hack//Link'' features characters from many previous entries in the series (Kite, Pi, Haseo, Midori, Albreio and so on) due to the fact that this is a 3rd version of the The World. The main character and villains however are entirely new.
* ''MarvelUltimateAlliance 2'' follows the rough plot of ''Comicbook/CivilWar'' but eventually split offs into an original storyline when [[spoiler:the nanites go rogue, creating a new villainous, [[TheVirus viral]] HiveMind intelligence known as the Fold. An evil cyborg Nick Fury being the closest thing the infection has for a figurehead effectively means they're more of a Original Generation '''concept''']].
* ''VideoGame/SDGundamGGeneration'' has a variety of original units which are Mobile Suit Variations (Prototypes which are handwaved to not exist in the anime). But the most prominent one is the Phoenix series of mobile suits which the Phoenix Gundam is said to be the strongest Gundam even in comparison to Anime/TurnAGundam. Along with that is a set of original pilots which either is just meant to be filler or is part of a side story plot.
** ''G Generation Wars'' play with this trope. You won't even aware of its existence until you unlock an EX mission, and it only appear in last two missions. Yet it turn out that events in the game was controled by ''Generation System'' super computer.
** And the GundamVSSeries gives us the two Extreme Gundams, the pilot of one of which is voiced by {{Gackt}}.
* ''DissidiaFinalFantasy'' has Cosmos as the BigGood and the guiding force driving the heroes to defeat Chaos. Chaos himself ''sorta'' counts as this too, as he's from ''Final Fantasy I'' originally, but has been [[AdaptationalBadass reinvented]] [[SuddenlyVoiced to]] [[AdaptationExpansion the]] [[BiggerBad point]] the only real similarities between his original incarnation and his ''Dissidia'' incarnation is their physical appearances and name. The ''Final Fantasy I'' Chaos was a generic demon OneWingedAngel transformation for Garland--''Dissidia's'' Chaos is a PhysicalGod and the BiggerBad to all previous Big Bads.
** Note that it's still implied that he is in fact the Chaos from ''VideoGame/FinalFantasyI'' seeing as rigorous time-and-dimension travel is explained to come into play through the reports in 012.
** Garland says that he and Chaos are the same thing in a cutsceen anyway. Despite Garland being TheDragon to Chaos in this game.
* While he's arguably an {{Expy}} of [[VideoGame/CastlevaniaCurseOfDarkness St. Germain]], newcomer Aeon is responsible for the events of ''VideoGame/CastlevaniaJudgment''.
* The ''Videogame/MarioGolf'' and ''MarioTennis'' series included original characters in the N64 Mario Golf, GBC Mario Golf and Tennis, and the GBA Mario Golf and Tennis versions, so that players would have a decent selection of characters to choose between in the former, and enough rivals and opponents, as well as as Playable {{OC Stand In}}s, in the latter four. Both GBC games can [[OneGameForThePriceOfTwo transfer their playable characters and their stats]] to their respective N64 versions, and the GBA and GC Mario Golf games follow in their footsteps.
* The Compati Hero Series, a Banpresto video game series which crossed SuperDeformed versions of Series/{{Ultraman}}, Franchise/KamenRider and [[MobileSuitGundam Gundam]], introduced a fourth hero in ''The Great Battle'' action game series called Fighter Roar. Roar is not a hero from any previous franchise, but a new character meant to represent Banpresto.
* The ''VideoGame/{{Parodius}}'' games have always had a greater or lesser number of {{Konami}} charaters in their player character roster. In the initial games the only character unique to the series was the octopus known as Takosuke in later games, but from ''Gokujou Parodius'' onward the number of original characters, not counting {{Expy}}s and {{Palette Swap}}s, grew steadily larger.
* ''Rockman Xover'', an [=iOS=] social game developed to commemorate the [=25th=] anniversary of the [[Franchise/MegaMan Rockman]] franchise, centers around a new Rockman named Over-1 who must rescue the other seven Rockman heroes.
* ''[[VideoGame/SegaSuperstars Sonic & All-Stars Racing Transformed]]'' has a small example, one of the secret characters is [[spoiler: a living {{Dreamcast}} VMU that morphs into vehicles from Sega's games]].
* ''VideoGame/DisneyPrincessEnchantedJourney'' has the heroine, the pixie, the Bogs, and the BigBad, [[spoiler:Zara]].
* Lord Fuse and Planet Fusion were created for ''FusionFall''.
* In ''VideoGame/PersonaQShadowOfTheLabyrinth'', Despite most of the cast being from ''VideoGame/{{Persona 3}}'' and ''VideoGame/{{Persona 4}}'', Zen and Rei are brand new character who debuted in ''Q''.
** And on a similar note, the UpdatedRerelease of ''VideoGame/Persona4Arena'', ''Persona 4: Arena Ultimax'' features the new character Sho Minazuki, who is the supposed BigBad of the game, and can be selected with or without a Persona.
* HyruleWarriors, a [[XMeetsY crossover spinoff of]] LegendOfZelda and DynastyWarriors, has already revealed multiple characters from the Zelda series that will either be playable or appear as a boss (if not both). However, there have also been three original characters revealed so far that will serve as the primary villains; Cia, a sorceress with a VillainousCrush on Link, Wizzro, an evil ring that was reborn into a sorcerer of darkness, and Valga, a BloodKnight who [[DealWithTheDevil sold his soul to Cia in order to gain power]]. Also, among the playable characters, we have Lana, a CuteWitch who apparently has some history with Cia.
* ''VideoGame/FightersMegamix'' has Deku the anthropormorphic Mexican jumping bean(!), Sibe, URA Bahn, a fighting chunk of meat on the bone, and the [=AM2=] palm tree amidst its roster of characters hailing from ''VideoGame/VirtuaFighter'', ''VideoGame/FightingVipers'', ''VideoGame/SonicTheFighters'', ''VideoGame/VirtuaCop'', ''VideoGame/RentAHero'', and even ''VideoGame/DaytonaUSA''.

[[folder:Western Animation]]
* Princess Lana and Kevin of ''WesternAnimation/CaptainNTheGameMaster'' serve two purposes. Princess Lana's storyline exists to create a single universe for all the crossovers to take place in along with a central plotline for the series to follow. Kevin exists to make sure that A) none of the other franchise characters is the star (which could piss off a licensee) and B) To make sure someone appealed to the target audience of game buying kids. Normally he would also be there to ensure nobody's character got derailed, but... well...
* (The Villain Whose Name Isn't) Shirley was ''literally'' created (in the most literal case of CreateYourOwnVillain ''ever'') in the third [[TheAdventuresOfJimmyNeutronBoyGenius Jimmy]] [[TheFairlyOddParents Timmy]] [[JimmyTimmyPowerHour Power Hour]].
* Reptil from ''TheSuperHeroSquadShow'', who later [[CanonImmigrant immigrated]] to the mainstream Marvel universe.
* Similar to Reptil, Evan Daniels/Spyke and Kaldur/Aqualad in their [[WesternAnimation/{{X-Men Evolution}} respective]] [[WesternAnimation/{{YoungJustice}} shows]] are series original characters, both with a number of similarities. They're both African Americans with blond hair, that were indirectly brought into the comics later but recived voal hatred from sections of the fanbase for reasons other than being series original. And, before all of them, Firestar in ''SpiderManAndHisAmazingFriends'', created because they couldn't get the copyright to use Johnny Storm.
* [[http://www.psychoandy.com/write/warriorking/index.html The Warrior King]] was a character created for a {{crossover}} event that spanned all four shows in USANetwork's "Xtreme Action Team" Saturday morning block: ''WesternAnimation/StreetFighter'', ''TheSavageDragon'', ''WesternAnimation/MortalKombat'' and ''WesternAnimation/WingCommander''.
* When RankinBassProductions [[CanonWelding welded]] several of its {{Christmas Special}}s to create ''Rudolph and Frosty's Christmas in July'' they wound up creating several new characters. Most notable is a BigBad named [[AnIcePerson Winterbolt]], a wizard who ruled the North Pole before Santa arrived. He worked with two lesser villains, a JerkAss businessman and an EvilCounterpart for Rudolph who had [[RememberTheNewGuy not actually existed in his previous specials]].
