In "Swamp Thing" (vol. 5) #36, when the Swamp Thing goes in the Rot to warn Abigail about the new realm of machines, she initially assumes that he is there because of Arcane, who has escaped. It is eventually shown that he has returned to Earth, but since he is not the avatar of the Rot, he can only gain strength from consuming rotten items, like corpses and garbage, and as such is terribly weakened. He joins forces with the new realm of Metal, which promises him the power that he lost, and his power does grow greatly in this time. He later poisons the Green from within, when the Swamp Thing is weakened in an attempt to destroy it, but this fails when all the avatars of the Green are awakened and use their power to cleanse the Green to its original state. Abigail challenges Arcane in the final war against Metal, and while she has the upper hand, Arcane eventually escapes.
