The X-Men are one of the most beloved superhero teams in the Marvel Universe, but Stan Lee's reason behind the creation of the team stemmed not from a desire to tell a unique story, but out of sheer laziness. The famed comic creator is known for his many contributions to comics: Iron Man, the Incredible Hulk, and perhaps his most famous creation Spider-Man.

The Incredible Hulk didn't have control over his abilities, Iron Man was an arms dealer looking to atone for his past sins, and Spider-Man was the first teenage superhero who notably wasn't a sidekick. But the origins were beginning to appear distressingly similar. Cosmic rays (for the Fantastic Four), gamma bombs and radioactive spider bites could only satisfy readers for so long before they realized the were all essentially the same origin: powers from a rapidly-introduced plot device. Lee needed something more and he found it in the genesis of the X-Men.
