Bass (フォルテ, Forte) is a character from the Mega Man universe.
Bass is a Robot Master created by Dr. Wily as an arch-nemesis to Mega Man, in an attempt to exceed his power. He debuted in Mega Man 7 alongside his partner Treble (who is much like Mega Man's Rush) as a villainous character, initially gaining Mega Man's trust only to later steal new enhancements from Dr. Light's lab to help Dr. Wily in his attempt at world domination. Bass is fought several times in the game, including at the end of the introductory level. After the final battle against Dr. Wily, he saves his creator from Mega Man's attempt at killing him. Bass is also playable in the game's secret two-player mode. In later games, he has adapted more of an anti-hero role, siding with Mega Man in a few games such as Mega Man: The Power Battle and Mega Man 2: The Power Fighters, and also being playable in games such as Mega Man & Bass and Mega Man 10, where he opposes Dr. Wily.
