For those of you, which is apparently all of you, who do not know your comic hero history:
Swamp Thing.
He once invaded Gotham (they arrested his girlfriend on trumped up charges) and turned the entire city into a mangrove swamp. When Batman tried to stop him, he beat Batman within an inch of his life.
