On an alternate Earth in the DC Multiverse, Thomas and Martha Wayne discover a crashed rocket with an alien baby inside, and raise him as their son, Bruce. Years later, on one fatal night, the Wayne family are walking through an alley when a lone criminal stops them. Bruce watches as his parents are gunned down, but the vicious attack activates Bruce's Kryptonian powers, causing him to lose control and burn the criminal with his heat vision. For years after his parents' deaths, Bruce chose to hide away in Wayne Manor, hating violence, until a group of robbers invades his home, prompting him to face the world with a new identity—the Batman.
