Cover Art of Swamp Thing (1986) #121.
*Now, Swamp Thing is alone. Abby has left to pursue a normal life after years of tolerating the weirdness and violence that attach themselves to the life of an Elemental. Tefe is secluded in a remote corner of the world with Lady Jane, a Parliament-appointed guardian and teacher. Now free of the trappings of human life, Swamp Thing's curiousity - and some powerful outside agency - lead him through a series of phantasmagoric tests. As these dangerous trials reveal Swamp Thing's hidden potentials, they bring him ever closer to his ultimate destiny. *Source: Back of card
