Super Mario Crossover 2 gives you the option to play the original Super Mario Bros game but with a different famous character. In this flash game you can pick between: Megaman, Bill Rizer, Simon Belmont, Bass, Ryu from Ninja Gaiden, and whole bunch more. You can also choose to play the NES or SNES versions of these characters. You can also play a survival version of the game. When a character dies in this mode, they are permanently gone unless you use a life to get them back between worlds (not levels).
