SPOILER: The ending features Mega Man defeating the Wily Alien, uncovering that it was just a projection all along. Wily gets on the floor and begs, like always. Mega Man is then shown walking home, with the four seasons passing. He then runs home, leaving his helmet on a hill. The credits roll follows.
Like many early Capcom games, the staff is credited through aliases, and not their real names. This results in some odd credits, such as "Music by Yuukichan's Papa" and "Special thanks to Fish Man." The only people credited by their real names are the designers of the eight robot masters.
