Ensemble Darkhorse / Mega Man

    Mega Man Classic 

    Mega Man X Series 

    Mega Man Zero Series 
  • Harpuia became a huge Ensemble Darkhorse during the run of the Mega Man Zero series because he was likable Anti-Villain that ultimately showed himself to be a Hero Antagonist and later full blown hero
  • The Zero series spawned a few minor/temporary ones, like Chilldre Inarabitta and Leviathon.
  • Omega. This Ax-Crazy psychopath was popular enough that he came back as a bonus boss in ZX. Of course, he's Zero, so this shouldn't come as any surprise.

    Mega Man ZX Series 

    Mega Man Legends Series 

    Mega Man Battle Network / Star Force Series 
  • Colonel.EXE, Protoman.EXE, Tomahawkman.EXE, Searchman.EXE, and Bass.EXE—freaking INCREDIBLY popular from the Mega Man Battle Network game/Mega Man NT Warrior anime-manga series.
  • Hyde became somewhat subject to this to those who watched the Tribe season of the Mega Man Star Force anime, as he was changed from a sycophant quasi-Dragon in the game to an out-there, comic relief artist in the anime. It didn't hurt that his crowning moment of villainy was kidnapping the hero's mother and throwing her off buildings and bridges Green Goblin-style just for the lulz.
