Which Street Fighter Alpha mode has Ryu and Ken fight M. Bison together?

Street Fighter Alpha’s Dramatic Battle mode has Ryu and Ken fight M. Bison together. It is a secret two-on-one mode that lets two players cooperate against the game’s principal villain.

The mode was inspired by the climactic battle in Street Fighter II: The Animated Movie, in which Ryu and Ken confront Bison. That connection gives Dramatic Battle a cinematic feel unusual for a mid-1990s arcade fighting game: two fighters share the screen and can attack the same opponent as a team.

In the original arcade version of Alpha, the matchup is specifically Ryu and Ken against Bison. Later versions and compilations broadened the idea. For example, Street Fighter Alpha Anthology includes a Dramatic Battle variant that allows players to select different character pairs and face a sequence of opponents.

This is why the mode can be confused with Arcade or Survival. Arcade is the standard single-player ladder, Survival tests how long a fighter can last, and Dramatic Battle is the cooperative format built around a team fight.
