Star Crash (スタークラッシュ,Sutā Kurasshu?) 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, the Star Crash does not use Weapon Energy when activated, using 3 weapon energy units if the shield is hit while protecting the user or 2 units if it's thrown, and can still be used if less than the amount of energy required remains. With a full weapon energy gauge, it can be shot 14 times or used as a shield 10 times.
