John Dee was a low-level LexCorp employee who was found guarding smuggled weapons in a company's warehouse, after a sweep by the Justice League. He was arrested and sent to Stryker's Island. There, he volunteered as a test subject for an experimental ESP machine dubbed the Materioptikon.Though he was outwardly a model prisoner, on good terms with the warden and guards, Dee harbored an inferiority complex and developed a strong desire to become powerful enough to defeat the Justice League and win the admiration of every super-villain. When his parole was denied and his wife Penny announced she had found someone else, Dee was pushed over the edge. During a prison mutiny, Dee sneaked into the doctor's lab and exposed himself to the full power of the ESP machine. At first, it drove him into a catatonic state, but when he woke up, it gave him full extra-sensory power. Then, he escaped prison and went after Penny. He got inside her dreams and dubbed himself Doctor Destiny, right before mentally torturing her into insanity (which ended up killing her). Then, Dr. Destiny pierced the dreams of Flash, Superman, John Stewart and Hawkgirl. He trapped each once of them in their dreams, playing out their deepest fears. J'onn J'onzz telepathically rescued his teammates one by one (except for Hawkgirl), and together they sparred Doctor Destiny in their dreamscapes. Meanwhile, John Dee was tracked down by Batman in the same LexCorp warehouse where he had been caught before. When he found himself unable to overpower Batman's mind, Dee attempted to inject him with a sedative. Instead, he accidentally injected himself with an overdose and was trapped in his own dreams. Dr. Destiny later seemingly recovered from his spar with the League, as he became a member of the Legion of Doom. He sided with Lex Luthor's faction when the Legion split, and survived the fight, but he was killed in the blast when Darkseid blew up the ship.
