BassDespite what Capcom's press releases state, Bass is not (and never will be) Mega Man's partner. The main reason why Bass is a playable character is because he wants to prove to Dr. Wily that he's the strongest robot ever, and he'll destroy anything, even Wily's own Robot Masters, to prove it.
Japan¶ This was the last game in cartridge format released for the Super Famicom in Japan.¶
Platform differencesThe GBA version has Bass' dash accessible by double tapping left or right, while on the SNES it was activated with the A button.
