While scientist Alec Holland was working on a formula to grow plant life where there is none, a rival organization vying for the formula, set off a bomb that covered Alec in his bio-restorative serum. To escape the flames of the explosion, he stumbled into a nearby swamp where he mutated into the strange hero known as Swamp Thing! Swamp Thing has superhuman strength and the ability to regenerate any portion of his body. He can also command plants to do his bidding and change locations instantly by inhabiting vegetation anywhere in the world.
