Marvel vs. Capcom is a series of crossover fighting games developed and published by Capcom, featuring characters from their own video game franchises and comic book series published by Marvel Comics. The series originated as coin-operated arcade games, though later releases would be specifically developed for home consoles, handhelds, and personal computers.

A fighting game is a genre of video game that involves combat between two or more characters. Fighting game combat often features mechanics such as blocking, grappling, counter-attacking, and chaining attacks together into "combos". Characters generally engage in battle using hand-to-hand combat—often some form of martial arts. The fighting game genre is related to, but distinct from, the beat 'em up genre, which pits large numbers of computer-controlled enemies against one or more player characters.
