Yes he is in a designated Spot and you need beat bass SP, first fight it in Undernet Zero, then go to the Graveyard, you�ll need the 200 Standars to pass a door then he is there, when you beat it he go and left a "Bass F" Chip, after that go to Underground, remember when you beat Megaman posesed by Gragar, there, Save before get there, when you beat MegaGragar again you�ll fight BASSFX the most dificult battle ever done.
I don´t use action replay to get *insert rare item, shiny poke, rare chip, etc.* i got it legally and right.
