Synopsis/Details
Jack Kirby is in Stan Lee's office, they're brainstorming, trying to come up with a new story for their comic. The story is set in the late 1950s, shortly after the Justice League of American had debuted in DC Comics. Stan Lee is trying to figure out a team which would rival the amazing Justice League.
Apparently, the two have been at it for a couple of days now and have come up with nothing. Lee suggests that they go out into the streets for a walk, citing that they may be inspired by something they see outside.
Kirby is skeptical. In that moment, a man enters the room, a man looking like a younger version of Stan Lee, telling them of their purpose. He tells them that they need to create the comics to facilitate the mental evolution of the younger generation, otherwise Mankind will not survive an enemy which will be borne of the Earth in the 22nd Century. The superhero stories will prepare the minds of generations and eventually lead to the physical evolution to deal with such enemies.
Stan Lee's doppleganger tells them this, giving them a showcase of the possible future. Then, he gives them access to a pool of knowledge which will inspire them to create the iconic characters we know of today.
