Know Man was originally a prehistoric man who happened to be in the vicinity of an alien ship landed on Earth thousands upon thousands of years ago. The craft's pilot, a member of the Controllers, had been assigned to Earth's space sector to prepare for the coming of a great cosmic threat, and was thus looking for a means of creating an "ultimate anti-war weapon". The Controller granted a primitive human male advanced mental capacities as well as immortality, thus turning him into Know Man. Accessing the Controllers' database, Know Man learned of humanity's fate and started to make preparations.

In the present day, he finally put his efforts to save Earth and its inhabitants in motion. Using Doctor Destiny, he gave an increasing number of ordinary humans superpowers, referred to by the media as a "genetic spark". At the same time, all previously existing metahumans and other super-powered individuals were given ordinary lives, with all recollections of their existence as non-ordinary citizens wiped from mankind's collective memory.

However, Doctor Destiny rebelled against being used by Know Man, and influenced events so seven former superheroes - Superman, Batman, Wonder Woman, Flash (Wally West), Green Lantern (Kyle Rayner), Aquaman, Martian Manhunter - would ultimately regain their memories of their superhero identities. Together, the seven thwart Know Man's plans and revert everything back to normal. Subsequently, they would form a new incarnation of the Justice League of America. Prior to his defeat, Know Man explained to the heroes that all he was trying to do was to prepare Earth for the coming of an "ultimate warbringer"

Later, when the JLA faced the threat of Mageddon, Batman recalled Know Man's warnings. Subsequently, part of the JLA's strategy to fight Mageddon consisted of temporarily providing the Earth's entire human population with superpowers, thereby repeating Know Man's strategy.
