History Analysis / FusionFic

* The fantastical form of IntercontinuityCrossover that brings together characters from multiple incompatible settings, either handwaving it with an explanation involving interdimensional portals and talk of a [[TheMultiverse multiverse]][[note]]such as ''VideoGame/KingdomHearts''[[/note]], or simply using RuleOfCool to sidestep the obligation to make any sense whatsoever[[note]]such as ''VideoGame/SuperSmashBros''[[/note]].

FusionFic is distinct from other crossover types, in that it blends the very ''premises'' of the works rather than merely putting their characters together. Either it puts the characters from work A into the general plot of work B, but with A's characters ''replacing'' rather than appearing alongside B's, or it blends together two [[TheVerse distinctive worlds]], or both.

There's also sort of a lightweight intermediate form between FusionFic and traditional IntercontinuityCrossover, where work A keeps its setting and premise 100% intact (aka "canon compliant" in fanfic terminology), while guest characters from work B[[note]]who appear in their own right, rather than replacing existing characters as in a straight FusionFic[[/note]] have their backstories altered (sometimes massively) to be compatible.

* {{Crossover}} between multiple works in a SharedUniverse, where it's already canon[[note]]or else [[CanonWelding retconned into being canon]][[/note]] that the characters from other works exist in the same world[[note]]Marvel and DC are especially known for this, with DC providing the TropeNamer for the large-scale version, CrisisCrossover[[/note]].

* The internally consistent form of IntercontinuityCrossover, where the crossover happens for reasons that mostly make sense in one/both universes. In some cases, both universes are generally realistic and could plausibly happen in the same place[[note]]Like when [[Series/EverybodyLovesRaymond Ray Barone]] showed up in a few episodes of ''Series/TheKingOfQueens''[[/note]]. In other cases, one/both already has an embedded concept of traveling to alternate universes, so a crossover is simply just another universe trip[[note]]''Series/Sliders'' crossovers often happen by them simply sliding into the series they're crossing over with[[/note]].

When most people think of a "Crossover", they think either

->'''A)''' {{Crossover}} between multiple works in a SharedUniverse, where it's already canon[[note]]or else [[CanonWelding retconned into being canon]][[/note]] that the characters from other works exist in the same world. Marvel and DC are especially known for this. Particularly large-scale examples of this fall under CrisisCrossover.

->'''B)''' The fantastical form of IntercontinuityCrossover that brings together characters from multiple incompatible settings, either handwaving it with an explanation involving interdimensional portals and talk of a multiverse, or simply using RuleOfCool to sidestep the obligation to make any sense whatsoever.

->'''C)''' The simple, mundane form of IntercontinuityCrossover that relies on both settings being mostly realistic to the point that they don't have mutually incompatible fantastical elements, to make it plausible that they would exist in the same setting without the need for any heavy-duty CanonWelding. Like when [[Series/EverybodyLovesRaymond Ray Barone]] showed up in a few episodes of ''Series/TheKingOfQueens''.
