* In ''[[https://www.fanfiction.net/s/11817327/1/Worlds-Collide Worlds Collide]]'', [[Franchise/TeenageMutantNinjaTurles Shedder]] quickly establishes himself as the more formidable villain. This especially becomes apparent in chapter 13, when he [[spoiler: exterminates Long Feng and the Dai Li]]. And on the day of the black sun [[spoiler: he kills Ozai.]] Even [[TheDragon Azula]] is terrified by him.

* In ''Fanfic/ShatteredSkiesTheMorningLights'', [[Manga/SailorMoon Chaos]] is the force behind Dead End, but as it can't take physical form, it uses [[Anime/SmilePrettyCure Joker]] as its [[TheDragon Dragon]] and public face.

* While she isn't the GreaterScopeVillain of the ''Franchise/KingdomHearts'' series, [[Disney/SleepingBeauty Maleficent]] certainly fills this role at various points throughout the series. [[VideoGame/KingdomHeartsI In the original game]], she's leading [[Disney/{{Hercules}} Hades]], [[Disney/{{Aladdin}} Jafar]], [[Disney/TheLittleMermaid Ursula]], [[WesternAnimation/TheNightmareBeforeChristmas Oogie Boogie]], [[Disney/PeterPan Captain Hook]], and WesternAnimation/{{Pete}} in an effort to find the Seven Princesses of Heart and unlock the gate to Kingdom Hearts, a vast repository of knowledge and power.

* Creator/MarvelComics 12-issue crossover series ''ComicBook/SecretWars'' has the godlike Beyonder abduct many of Earth's mightiest heroes (Fantastic Four, Avengers, the X-Men, Spider Man) and likewise Earth's most dangerous villains (Absorbing Man, Ultron, Galactus, Enchantress).

Sister trope of CrossoverComboVillain, which takes all of the villains (or elements thereof) and rolls them into one character. Related tropes include VillainTeamUp, LegionOfDoom, and MonsterMash. See GreaterScopeVillain for cases where the head villain is a new character created specifically for the crossover.

Contrast OriginalGeneration when the writers choose to create a new character (in this case, as the main villain).

[[{{Crossover}} Crossovers]], more than almost any other kind of story, can get audiences excited based on little more than the idea alone. While that may be a good thing for publicity, a really good crossover can be extremely hard to write. Since you're already working with established characters that have their own stables of fans, you're already dealing with the baggage of fan expectations, and the pressure to get each of their beloved characters ''just right''.

However, the Crossover Villain-In-Chief need not be [[GreaterScopeVillain ultimate evil entity]] of the overall story; they only need to be the leader of a group of other villains. It's not unheard of for the Villain-In-Chief to be controlled, manipulated, or otherwise employed by a greater malevolent force, be it knowingly and willingly or not.

[[spoiler:Unbeknownst to him, All For One doesn't see him as an equal at all, and [[UnwittingPawn just wants to use him]] to further Shigaraki's ascension.]]
