No one knows what to make of the mysterious new NetNavi Bass, but everyone is intruiged when it seems that he alone can resist the CyberBeast that's slowly destroying the entire Cyber Network! What will he do with that kind of power? What does he want? And whose side is he on: MegaMan's? Grave's? Taking no chances, Kid Grave sends FreezeMan to delete Bass. Then Bass makes off with an unconscious MegaMan, launching Lan and his friends on a desparate search to find him. And worst of all: Mr. Wily has returned.
