Doctor Destiny (John Dee) is a supervillain appearing in American comic books published by DC Comics. Jeremy Davies played the character in his live-action debut on the Arrowverse crossover "Elseworlds". David Thewlis plays a version of the character in the television series The Sandman. Publication history Doctor Destiny first appeared in Justice League of America #5 (June 1961), and was created by Gardner Fox and Mike Sekowsky. Fictional character biography Doctor Destiny was once a petty criminal scientist who used his genius to create astounding devices for crime. He first encountered the Justice League of America shortly after he invented an anti-gravity device and will-deadener beam that allowed him to capture Green Lantern by luring him into his base by using anti-gravity discs to fly over the city as Green Lantern to impersonate and infiltrate the JLA. Before Destiny could further his criminal ends, the League discovered his treachery as Green Arrow had heard from an underworld informant that a member of the League had been captured and was being impersonated. The League was captured by his will-deadening beam which also had kryptonite as an element. Destiny then revealed he planned to send his ship into space, thus getting rid of the JLA.

Green Lantern was able to free himself during the drain and promptly imprisoned Destiny and his two henchmen.

He manipulated the Dreamstone, forcing flaws and adding circuitry, until it was attuned to him and not the Dream King. Morpheus was imprisoned by Alex Burgess at the time, unaware of what Destiny was doing and unable to stop or prevent it. Doctor Destiny's power was so great that the Justice League resorted to drastic measures to stop him. They hypnotized him and manipulated his psyche to prevent him from dreaming; this kept him from using the Materioptikon for criminal purposes but caused him to lose his mind and shrivel to a skeletal wreck of a man. He was then sent to Arkham Asylum, where his sanity eroded further. He escaped
