Star Crash

Star Crash (スタークラッシュ) is Star Man's Special Weapon. This weapon creates a star-shaped barrier around Mega Man for protection, and it can be fired at enemies in the direction he is facing. Star Crash can resist only one hit, and excluding shots fired by Dark Man 4, it can protect against every enemy bullet in the game.

In Mega Man 5, Star Crash is Gravity Man's weakness. It is also slightly effective against Dark Man 4 and Wily Press.
