The Man of Steel and the Dark Knight have arrived at the compound of Niles Caulder-the Chief in charge of that strange band of misfits known as the Doom Patrol-but all is not as it seems. While Batman works with Niles to cure Superman of his freakish transformations, a side mission to track a mysterious figure known as "the Demon" attracts the Dark Knight's attention-and moreover, it could have some connection to Superman's poisoning at the hands of Metallo! It's danger, intrigue, and the surprise appearance of Deadman in chapter two of World's Finest!
