Rogue Noise (ブライノイズ Burai Noizu?) is the secret Noise Change of Mega Man, with unique abilities. It can be considered Mega Man empowered with Mu technologies. It has the same encounter rate in both Black Ace and Red Joker, and cannot be stored by the Noism in Astro Wave 1 to revert to. True to Rogue's beliefs, Rogue Noise can only be acquired while the player has no real Brothers, and prevents him from forming any BrotherBands with other players as well. BrotherBands with in-game NPCs are unaffected by this Noise's restrictions.
