Gillman

The Gillman is fully amphibious, capable of breathing both in and out of the water. It possesses superhuman strength, and large, webbed hands with sharp claws on the tip of each finger. The Gillman's scaly skin is extremely tough, which combined with a fast acting healing factor, allows it to survive wounds which would be fatal to humans, such as gunshots and full immolation.
