Intercompany crossovers in comics

Intercompany crossovers in comic books consist of comics in which characters and other elements owned by one publisher appear together and interact with ones owned by another. Such occurrences within the medium of comics as opposed to other types of media are notable, given the regularity of canonical crossovers between characters and series under a single publisher, particularly in DC Comics and Marvel Comics, where they constantly affect mainstream continuity for the parties involved. As a result, intercompany comics crossovers are less common, and usually take the form of one-shots or miniseries that are not canonical to the history of the characters that are featured.

Notable crossovers between Marvel and DC include 1976's Superman vs. The Amazing Spider-Man,^[1] 1996's DC vs. Marvel, 2003's JLA/Avengers and the Amalgam Comics imprint, which featured original characters conceived as amalgamations of famous DC and Marvel characters. Examples of crossovers between the "big two" and smaller publishers include Batman/Teenage Mutant Ninja Turtles and Archie Meets the Punisher. Other collaborations between comic publishers might not consist of conventional crossovers and instead feature original characters or ones from other media, such as WildStorm (a subsidiary of DC Comics) and Dynamite Entertainment's 2007 miniseries Freddy vs. Jason vs. Ash.^[2] In 2025, Ian Flynn wrote the five-issue miniseries DC X Sonic the Hedgehog.^[3]
