Marvel vs. Capcom

Marvel vs. Capcom is a series of fighting games created by Capcom in which characters created by Marvel Comics and Capcom's own characters appear together. While it was the first vs. series involving Capcom, the name Marvel exists to distinguish it from Capcom's other vs. series with SNK (Capcom vs. SNK) and Namco's crossover RPG with Capcom (Namco x Capcom).

The Marvel characters depicted in these games were often based on their incarnations in various early 1990s animated series (particularly X-Men), and were often voiced by the same voice actors.

Many of the characters and fighting mechanics used in these games were first developed and refined in two other fighting games Capcom had developed earlier, serving as precursors to the series: X-Men: Children of the Atom, which featured characters strictly from the X-Men universe, and Marvel Super Heroes, which gleaned characters from Marvel's entire roster (X-Men included).

Although the tag-team fighting concept was not new, it was refined with this series (although fans would argue whether this was for better or for worse). New fighting game terminology, such as "Aerial Rave" (the act of performing a combo on an opponent while the opponent remains airborne) and "Variable Combination" (the act of having two or more characters on the same team to perform their hyper combos at the same time) were added to the fighting game vernacular with this series.
