Kanigance

Kanigance (カニガンス) is the giant crab mid-boss in Mega Man 7, and it appears in Burst Man's stage and in Wily Stage 3 if the player took the lower route. It shoots energy from its claws, spits damaging bubbles, and tries to ram Mega Man. When destroyed, it makes the fluid that's around to change such that Mega Man will float, which is dangerous especially in Wily Stage 3 because he runs the risk of hitting instant-death spikes. He is weak to Junk Shield and Slash Claw.
