Tatsunoko vs. Capcom: Ultimate All-Stars is a crossover fighting game developed by Eighting and published by Capcom. The game features characters from both Capcom's video game franchises and various anime series produced by Tatsunoko Production. It was originally released in Japan for arcades and the Wii video game console in December 2008 as Tatsunoko vs. Capcom: Cross Generation of Heroes . Following high demand from international fans, Capcom worked with Tatsunoko to resolve international licensing issues and a second version, Ultimate All-Stars, was released for the Wii in North America, Japan, and Europe in January 2010, featuring additional characters and online multiplayer.

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.
