Dust Crusher (ダストクラッシャー,Dasuto Kurasshā?) is a worm-like enemy that appears in the junk piles in Junk Man's stage. It normally just goes back and forth, but if Mega Man stands still for too long, a periscope (actually its eye) raises and the Dust Crusher lunges towards him. The Slash Claw can take it out in one hit.
Dust Crusher's Japanese name is the same as that of a Special Weapon, but it can also be translated as "Dust Crasher" or "Dust Clasher".
