Swamp Thing is a character created by Len Wein and Bernie Wrightson. When the scientist Alec Holland was killed in an explosion, the chemicals he was covered with spilled on the plant life of the local swamp, creating the Swamp Thing, an humanoid being made of plants. The cosmic entity knows as the Green gave Swamp Thing superhuman strength, invulnerability, the ability to control plant life, and the ability to control the weather, abilities that Swamp thing uses to protect the innocent and fight the forces of evil.
