Swamp Thing

Swamp Thing may not have the good looks of your typical superhero, but this humanoid mass of vegetable matter is dedicated to protecting his swamp home, the environment in general, and even humanity — though he is feared and rejected by most people. His powers include being able to take on the form of surrounding plants and to control the growth and movement of plant life.
