Acoustic Blaster

Acoustic Blaster is the Special Weapon used by the Roboticized Master Vector Man in the crossover Worlds Collide. The weapon fires a large blast of sound in the shape of a musical note. After subduing Vector Man and restoring him to his original identity, Vector the Crocodile, Mega Man copied the Acoustic Blaster and then proceeded to use it on Charmy Man, significantly weakening him due to it being Charmy Man's weakness. Mega Man later tried using it on Knuckles Man, but the Roboticized Master shattered the ammo with a single punch. In the Wily Egg, Mega Man used this weapon to shoot Bass in the face.

Mega Man's colors when using this weapon are green and lime.
