Noise Crush (Mega Man)

Noise Crush, also known as Crash Noise and Crush Noise (クラッシュノイズ Kurasshu Noizu), is Shade Man's special weapon. It fires a powerful sound wave to damage enemies. If the wave hits a wall, it will bounce off it. If it comes in contact with Mega Man, he will charge automatically, and he can then discharge a powerful wave. The charged wave is larger and will do more damage to enemies.

In Mega Man 7, this weapon is Turbo Man's primary weakness and hitting him with repeated Noise Crush waves will prevent him from using his Scorch Wheel.[1]  If Noise Crush is fired as soon as the player enters the boss room, it will kill Turbo Man instantly. This bug also affects Spring Man and Cloud Man (with the Danger Wrap), although in Cloud Man's case, it destroys the entire room and instantly kills the player.[2]
