Mega Man Universe is based on Mega Man 2

Mega Man Universe, we surmised from the very beginning, is an amalgamation of familiar elements in a new presentation. According to producer Akiko Ito, it'll contain even more familiar elements than we've seen: the levels and bosses of Mega Man 2.

Ito told Joystiq during an interview, "The base story and the base game is taken from Mega Man 2, so players can experience Mega Man 2 through this game." She explained that these "default" stages don't have to remain in their original form, as well: "Basically, we're going to create the stages from Mega Man 2 faithfully in this new style, and you can play them as is, or you can customize different sections of them, or you can customize all of it if you want to, so pretty much you can do whatever you'd like with the stages."

We're calling it right now: the most popular player-created stage will be "Quick Man, but without those laser things."
