Complete story — includes the ending
Batman and Wonder Woman arrive at the Fortress of Solitude to celebrate Superman 's birthday. They soon discover that he is being held captive by Mongul in the fortress, and is under the effects of a parasitic plant known as the Black Mercy, which has left him prisoner in a dream world where Krypton was never destroyed and he leads an idyllic life. Batman and Wonder Woman find themselves forced to snap him out of this fantasy, knowing it could prove disastrous for the League.
