Good news for Mega Man fans!  I recently finished a video walkthrough for Mega Man II, the Gameboy game. Watch as Mega Man goes up against four bosses from the NES Mega Man 2 game: Wood Man, Metal Man, Air Man, and Clash Man (who is apparently related to Crash Man).  Then, watch as Mega Man fights four bosses from the NES Mega Man 3 game: Magnet Man, Hard Man, Top Man and Needle Man.

There's also a plotline about Mega Man fighting an evil version of himself from the future, but unless you have the booklet that came with the game, you won't know about it.
