Albert Wily

Doctor Albert Wily is a German scientist who grew jealous of his partner's (Dr. Thomas Light) talent and praise from all, and decided to hijack robots from Light to take over the world. Needless to say, his plans failed due to one robot: MegaMan. Well, mostly. He has built robots of his own, and is a skilled enough engineer to be able to not only build his own robots from scratch, like Bass, Treble, and Zero, but turn something innocuous, like a yo-yo, into something deadly, like a spinning blade. Real example there, y'all. Anyway, point is, he's really smart, but always ends up with the same strategy.
