Alec Holland – who has lived a normal life as a human for nearly a year, with Ruth Monroe as his girlfriend – finds himself beginning to slowly change back to his Swamp Thing form, so he begins creating an active bio-restorative formula once more in an effort to reverse the change. Dustin Clayburne recruits Alec to help the Challengers of the Unknown against the minions of M'nagalah, but as he does so, he rapidly changes back into Swamp Thing, this time irreversably. Shortly after, Swamp Thing's mind is taken over by Multi-Man, who uses him to break him out of jail. The Challengers and Deadman free Swamp Thing, who joins the team for a short while as they search for a cure for his condition.

Meanwhile, the Challengers recruit the Justice League of America and various heroes to defeat the time-monsters in the present.
