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 him out in 1 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".
