Mega Man: The Power Battle and Mega Man 2: The Power Fighters first appeared in Japanese arcades before being ported to the Neo Geo Pocket Color and eventually the PS2 and GameCube as part of the Mega Man Anniversary Collection in 2004. The first game follows the events of Mega Man 7 while the second follows on the heels of Mega Man 8.
In Mega Man: The Power Battle, players choose between three characters: Mega Man, Proto Man, and Bass, and then select a story and stage. Though the controls were largely similar to standard Mega Man gameplay, there was no action-platforming level to traverse. Instead, players jumped straight to a battle against a Robot Master, earning a weapon that would then make the next fight a bit easier.
The sequel added Duo to the mix as a fourth playable character. Completing the game with each of the characters revealed a different ending.
