Comic Book Terms – Crossover
What is a Crossover? A Crossover is a story where one character or more characters appear prominently in a story with another character or characters. (also called “x-over”).
Crossovers can be both internal and between different universes and companies. At their most basic level, a crossover can refer simply to a character making a guest appearance in a different comic, but typically a “crossover” implies more than a simple appearance, and denotes a cohesive storyline spanning more than one title, often as part of an event. Typically, crossovers are more than two-issues in length, and often span multiple titles, rather than just two. Most crossovers occur within the confines of a shared universe, although crossovers between universes also occur.
