Shark Boomerang

Shark Boomerang is a special weapon that Mega Man obtains by defeating Shark Man in Mega Man 3 for the PC. It fires a three-bladed boomerang, presumably sharpened around the edges, straight forward.

It is Blade Man's weakness, as it can go through his fired blades, and hit him quickly. It looks very similar to the Gyro Attack and acts like Rolling Cutter in that it returns to Mega Man.
