Dr. 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 that allowed him to capture Green Lantern, impersonate him, and infiltrate the JLA. Before Dr. Destiny could further his criminal ends, however, the Leaguers discovered his treachery and promptly imprisoned him.

He then created the Materioptikon, a device which allowed him to create reality from the fabric of dreams. In a later retcon, his mother, Ethel (the former mistress of Roderick Burgess), gave him Morpheus' Dreamstone, which powered the device. He manipulated the Dreamstone, forcing flaws and adding circuitry, until it was attuned to him and not the Dream King. Morpheus was imprisoned by the Burgess at the time, unaware of what Dr. Destiny was doing and unable to stop or prevent it.

Dr. 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.

When his mother died, Dr. Destiny escaped Arkham, reclaimed the Ruby, and used it to initiate a rampage where he killed dozens of people. The Sandman, recently freed and searching for his stolen tokens of power, could not stop Dr. Destiny until the villain decided to leech all of the Sandman's power into the Ruby and destroy the gem. The destruction of the Dreamstone returned all of its power back to the Sandman, including power the Lord of Dreams had been without for millennia. Morpheus then returned Dr. Destiny to Arkham and returned his ability to dream. Although he is able to dream once again, Dr. Destiny's sanity is still extremely shaky.

Dr. Destiny later learnt that continued use of the Materioptikon meant he still had some dream manipulation powers even without the Dreamstone. He warped the Atom's dreams of the original Justice League into a world where the superheroes were fascist bullies, as part of a plan to trap the then-current Justice League there. He was defeated when the comatose Blue Beetle was able to enter the dream world. Later, Dr. Destiny threatened the JLA once again by bringing his "dream self" into the real world and attacking them with bizarre and irrational dream-logic. He was defeated and returned to his cell in Arkham.

Over the years, Dr. Destiny has proven one of the Justice League's most persistent foes. In his earliest appearances, before he lost his sanity, his goals were more rational: to acquire wealth and personal power, to eliminate all his enemies, and so on. All of these schemes revolved around the creative and liberal use of the Materioptikon, a strategy which often caught his opponents off-guard. One can assume that Dr. Destiny is still interested in attaining all of his former goals: the elimination of the Justice League, the restoration of his human appearance, and the reconstruction of the Materioptikon.
