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. 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.

In Tatsunoko vs. Capcom, players engage in combat with a team of two characters or with a single giant character and attempt to knock out their opponents. It is the seventh Capcom-designed installment in their Vs. fighting game series, which includes the Marvel vs. Capcom and Capcom vs. SNK series, and the first to be fully rendered in 3D graphics. The game is set in a 2.5D environment; characters fight in a two-dimensional arena, but character models and backgrounds are rendered in three-dimensional graphics. The game is designed around a simplified three-button attack system, which was inspired by the simplistic control schemes commonly used by both the Vs. series and the Wii.
