Shark Man

Shark Man is one of the six Robot Masters from the Mega Man 3 (PC) computer game for DOS and is part of the CRORQ series of Robot Masters.

Shark Man resides deep in the ocean and requires those who seek to do battle with him to swim through hordes of enemies in order to find him. He is very mobile in the water and uses his signature Shark Boomerang to take out opponents at a great distance. However, Shark Man is weak against Bit Man's Bit Cannon weapon, which has the ability to drill deep into his thick armor while moving quickly through the water.
