What If... Superman Lived in the Marvel Universe?
His story is a familiar one. Born on the doomed planet of Krypton, baby Kal-El is lovingly placed aboard the rocket ship that will be his salvation. After a tearful goodbye, the rocket ship is fired into space mere moments before his home world is destroyed.
The rocket ship is launched into light speed as it heads to space. This causes the journey to become slightly unpredictable as the rocket not only tears through the fabric of time, but this time reality.
The rocket carrying baby Kal-El disappears from one universe and reappears in another.
This baby Kal-El will likely not be raised by the Kents (although not impossible.) He will not become the hero of a city called Metropolis. He will never meet a woman named Lois Lane or his pal Jimmy Olsen, or even have legendary battles against a brilliant criminal mastermind named Lex Luthor. He will never meet Batman, Wonder Woman, and the rest of the Justice League.
The rocket still heads for a planet called Earth, but is a different Earth.. one located in the Marvel Universe...
