Swearing vengeance, Dominus telepathically entered Superman's mind and preyed on one of the Man of Steel's greatest weaknesses; his fear of failing the people of Earth. Using mind control, Dominus convinced Superman to take control of Earth and build the Superman robots to police the planet 24 hours a day, seven days a week forever. In another battle, Dominus used his reality-warping powers to become Superman, using the Superman robots to search for Kismet while Superman was disguised as one of his own robots and later as Dominus. During his captivity in these other forms Superman improved on his use of Torquasm Vo, an ancient Kryptonian warrior discipline technique where the warrior can control what they think. Superman and Dominus then engaged in a mental-physical battle with Dominus using any stray thought of Superman to reshape reality. The battle ends with Superman banishing Dominus to the Phantom Zone. Doomsday Double Down Double Down aka Jeremy Tall was introduced in The Flash: Iron Heights by Geoff Johns and Ethan Van Sciver. A con man and compulsive gambler, Jeremy Tell gained his powers following a card game in which he lost. Incensed, he attacked and killed the man who had beaten him. The man had in his possession a cursed deck of cards, which cleaved to Tell's flesh and burned off much of his skin. The cards now act as the top layer of his skin, and can be wielded as weapons. During his time in prison, the serial killer Murmur released the Frenzy virus at Iron Heights. Tell tried to escape in the ensuing mass breakout, but was stopped by Pied Piper. He was taken back to solitary confinement. A later attempt to break out was successful. After escaping Iron Heights, he and Girder were both hired by Penguin to help him establish a crime ring in Keystone City, but was stopped by Flash and Nightwing.
