It didn't come with any. Also, the Mega Man 3 DOS port has several ripoffs of the other Masters. "Wave Man" is just Air Man with water jets in place of a fan, for instance.
There's also Megaman 3 DOS, the sequel. There was never a Megaman 2 DOS. Now, Megaman 3 DOS is really strange. The enemies are mostly weird mix-and match animals and guys in hazmat suits, nevermind Megaman followed the first rule of robotics, and all of the levels seemed to take place in modern times in places like oil refineries and oceans, not in futuristic bases. It was almost as if the designers just put Megaman over some scrapped Eco-Garbage game. But yeah, that game sucks. Which is why I love it.
