{{Crossover}}s occur any time characters from one work "cross over" into another. Any time characters from one work interact with another work, you have a crossover.

This is extremely common in FanFic, where the authors take someone else's characters and play with them, often introducing a new setting or new characters in order to better facilitate the story they want to write.

This is an index of the varying types of crossovers; RuleFifty may apply to some of these.
----

* '''{{Crossover}}''' (main trope)
* AdaptationAmalgamation: A crossover that's an adaptation of both/all the works being crossed.
* BatFamilyCrossover: A crossover that only affects people in one immediate in-story location.
* CanonWelding: An author takes two previously-unrelated works they made and fuses them together into one universe.
* CharacterOverlap: When certain characters have a tendency to do the crossing over.
* CommonCrossover: When two works have a tendency to be crossed over in FanFiction.
* CompanyCrossReferences: Two works owned by the same company [[ShoutOut reference]] each other, or one references another, in-story but they don't actually cross over except for occasions when a character briefly appears.
* CrisisCrossover: A crossover between all the works within a SharedUniverse.
** CrossThrough: Similar to a CrisisCrossover, but without inter-work character interaction; a storyline starts like an installment of one work, then switches to different works within that universe.
** RedSkiesCrossover: Similar to a CrisisCrossover, but while all the ''works'' in a universe are affected, the ''characters'' don't all meet each other.
* CrossoverAlternateUniverse: An AlternateUniverse that exists solely for the purpose of making a crossover.
* CrossoverComboVillain: When a crossover creates a new villain by combining elements from both stories.
* CrossoverCosmology: A crossover between different religious mythologies (e.g. [[Myth/NorseMythology Thor]] hanging out with [[Myth/ClassicalMythology Zeus]]).
* CrossoverCouple: Two characters from different works fall in love.
** CrossoverShip: Like a CrossoverCouple but [[{{fanon}} non-canon]]; {{shipping}} two characters from different works together.
* CrossoverExclusiveVillain: A villain exclusively created for a {{crossover}}, with often no relation to previous canon.
* CrossoverFinale: The [[GrandFinale final installment of the story]] is also a crossover with another work.
** FullyAbsorbedFinale: When a show's finale ''isn't'' grand, because it's wrapped up in an episode of a different show set in the same universe.
* CrossoverPunchline: A crossover that's just a brief joke.
* CrossoverVillainInChief: When universes collide, one villain rises up to lead the others.
* DeconstructionCrossover: Lots of works in one genre are crossed over in order to {{deconstruct|ion}} (or {{reconstruct|ion}}) the genre.
* DoppelgangerCrossover: A FanFiction that crosses two works that feature the same actor playing different characters.
* FairyTaleFreeForAll: A crossover between a lot of different FairyTales.
* FakeCrossover: A crossover that is not FanFiction, but is not officially canon either.
* FusionFic: A {{fanfic|tion}} where the characters in one work replace the characters in another.

* IntercontinuityCrossover: A crossover between two stories that are not set in the same universe.
* IntraFranchiseCrossover: A crossover between different adaptations of the same work.
* LawyerFriendlyCameo: It's legal to have a crossover without permission, if you make it so that [[{{expy}} technically they're a different character]], or you censor the character a bit.
* MassiveMultiplayerCrossover: A crossover between more than two works (often ''many'' works).
* ModularFranchise: Two media franchises created by the same company become one.

* RequiredSpinoffCrossover: A spin-off and its parent show do a crossover.
* SharedUniverse: Multiple works of fiction are set in the same overall continuity, which allows for occasional (fully canon) crossovers.
* SidelinedProtagonistCrossover: When crossovers don't revolve around the main hero from one or more of the involved stories, or {{demote|dToExtra}}s them to supporting characters.
* SirCameosALot: A character who appears in more cameos and crossovers than they do in their own original works.
* StoryBreakerTeamUp: A crossover that doesn't work very well.
* SpiritualCrossover: A crossover that uses a bunch of CaptainErsatz characters instead of the originals.
