Mario X Street Fighter

Mario X Street Fighter is a cross-over fighting game between the Mario and Street Fighter franchises.

Plot
While Mario was fighting Bowser in the Pipe Maze, trying to save Princess Peach, something happened. In another dimension, Chun-Li had finally confronted her enemy, M. Bison, in the sewers, where they were having their final battle. She kicked Bison, sending him into a hidden Warp Pipe, while at that same time Mario kicked Bowser, sending him into the other end of that same Warp Pipe. Both Bison and Bowser were sucked through the Pipe at once, and were fused together into M. Koopa! M. Koopa decided to use his power to destroy both universes at once and take over the multiverse, forcing both the Mario universe characters and the Street Fighter universe characters to work together!
