25. He Created the Fantastic Four in 1961
DC Comics successfully launched the Justice League of America in March of 1960, which featured Superman, Batman, Wonder Woman, The Flash, the Green Lantern, et al. Stan Lee’s superiors at Marvel asked him to create a comic that could compete with the Justice League, so he came up with a collection of four characters – the Thing, Mister Fantastic, Invisible Girl, and the Human Torch – who together formed a team known as the Fantastic Four.
