Next week's "Justice League" #24 reveals the origin of Ultraman, the evil Superman from Earth 3 -- and here's an exclusive peek at the opening pages.

We've seen the final days of Superman's Krypton many times before -- but what about the doomed home planet of Ultraman, the alternate-universe evil Superman from DC Entertainment's Forever Evil event? Our exclusive preview of next week's Justice League #24 reveals all.

The issue, by Geoff Johns, Ivan Reis and Joe Prado, gives readers some background into the leader of the Crime Syndicate, the parallel Justice League from Earth 3 that turned up at the end of the "Trinity War" storyline and immediately set about taking over the world. What is he really doing on Earth -- and does his origin offer clues to how he can be stopped? (Spoilers: Kryptonite isn't going to be any use; that just makes him stronger.)
