Ring Boomerang

Ring Boomerang is Ring Man's power. It has a somewhat limited range and, as its name implies, boomerangs back. But it can do multiple hits if aimed correctly. The Ring Boomerang can also pierce Skull Man's Skull Barrier, causing normal damage to the robot even when he's shielded. The Weapons Archive in Mega Man 10 also uses the Ring Boomerang.
