Swamp Thing

The Swamp Thing (Dr. Alec Holland) is a fictional character and antihero in comic books published by DC Comics. He is a humanoid/plant elemental creature, created by writer Len Wein and artist Bernie Wrightson. Swamp Thing has had several humanoid or monster incarnations in various different storylines. He first appeared in House of Secrets #92 (July 1971) in a stand-alone horror story set in the early 20th century. The character then returned in a solo series, set in the contemporary world and in the general DC continuity. The character is a swamp monster that resembles an anthropomorphic mound of vegetable matter. He fights to protect his swamp home, the environment in general, and humanity from various supernatural or terrorist threats.Swamp Thing can inhabit and animate vegetable matter anywhere, including alien plants, even sentient ones, and construct it into a body for himself. As a result, bodily attacks mean little to him. He can easily regrow damaged or severed body parts, and can even transport himself across the globe by leaving his current form, transferring his consciousness to a new form grown from whatever vegetable matter is present in the location he wishes to reach. He even grew himself a form out of John Constantine's meager tobacco supply on one occasion.

Swamp Thing is normally human-sized or slightly larger than average, but he can grow bodies much larger. He once used Sequoioideae to grow a body the size of an office block. Swamp Thing possesses superhuman strength. While Swamp Thing's strength has never been portrayed as prominently as many of his other abilities, he is arguably one the most powerful beings in the DCU. Swamp Thing can control any form of plant life. He can make it bend to his will or accelerate its growth. This control even extends to alien life, as he once cured Superman of an infection caused by exposure to a Kryptonian plant that was driving Superman mad and causing his body to burn out its own power.
