Ring Boomerang (Mega Man)

Ring Boomerang (リングブーメラン Ringu Būmeran) is Ring Man's Special Weapon. It has a somewhat limited range and, as its name implies, boomerangs back, but it can do multiple hits if aimed correctly. It's Dust Man's weakness, but Dust Man is immune to the Ring Boomerang when he has his vacuum on. It is also the weakness of Mothraya, Tako Trash, and the first form of Wily Machine 4. The Ring Boomerang can also pierce some shielded enemies, like Shield Attacker and Skull Man's Skull Barrier. In Mega Man IV, the Ring Boomerang can take items and pull them to Mega Man. Ring Boomerang can also destroy Garyobies.

The Ring Boomerang is also used by the "Bridge" in Mega Man IV and the Weapons Archive in Mega Man 10.

Ring Boomerang is the only weapon besides the Dust Crusher and Mega Buster to be able to damage the Cossack Catcher.
