Swamp Thing (1985-) #166

A year has passed since the Swamp Thing was last seen, and the U.S. government sends Jason Woodrue, the man who discovered Swamp Thing's true nature, to navigate the now-unearthly landscape of the Louisiana bayou in search of the Earth Elemental. But Swamp Thing may be as altered as his environment…and John Constantine and the Phantom Stranger have their own plans for dealing with what he's become.
