Mega Man & Bass

Mega Man & Bass is an entry in the classic Mega Man series, with option for controlling either Mega Man or Bass, due to Dr. Wily and Dr. Light making a truce to fight against King. The game was originally released only in Japan, but a later Game Boy Advance port had an international release.

After Mega Man 8, Dr. Wily's whereabouts were still unknown, and he built a new castle to prepare his comeback. But a robot calling himself King appeared planning to conquer the Earth, believed that robots were not meant to simply serve humans, but rather that they were superior and therefore should rule the Earth.
