Episode Title:For the Man Who Has Everything.Episode Description:Batman and Wonder Woman find Superman held captive by Mongul in the Fortress of Solitude and dreaming of an idyllic life on Krypton, courtesy of a wish-fulfilling parasitic plant known as the Black Mercy. This episode is adapted from a popular story written by Alan Moore and illustrated by Dave Gibbons for Superman Annual #11 in 1985. This also marks the first, and only appearance by Joe Chill in the DCAU[citation needed], as Batman's idyll is revealed to be watching his father beat the thug senseless over and over.
