DC Comics has been teasing a big event coming in October, tying into the ongoing DC All In story and the mystery of what, exactly, happened to the big baddie Darkseid. And now we know what that event is: DC K.O., a “knock-down, drag-out fight” between the DC super heroes to save the universe from Darkseid.
Written by Scott Snyder and Joshua Williamson with art by Javi Fernández, as revealed over at The Hollywood Reporter, the event will include 36 fighters in a tournament of champions type situation. The video-game style plot finds Earth separated into a five-level gladiatorial arena, with winners generating Omega Energy in order to be crowned the champion, King Omega, a being with enough power to take on Darkseid himself.
The series will run five issues starting on October 8, and will continue through 2026 (so presumably, monthly). Front and center in the story will be Superman, who Snyder teases will be “looking into his own heart of darkness.” And while that seems to indicate the Man of Steel will come out the winner, Williamson notes that “unexpected heroes” will win the challenges and go farther in the tournament in surprising ways.
Alongside a main cover featuring an acetate overlay (the full cover will be revealed at DC’s panel at San Diego Comic Con on July 25), there will be variant covers by Jim Lee, Daniel Warren Johnson, Frank Cho, Scott Koblish, Jae Lee, Mike Del Mundo, Ben Oliver, Noobovich, Dan Mora, Mark Spears, and a foil variant by Fernández.
But wait, there’s more! Before the main series will be a prelude story, Justice League: The Omega Act #1, written by Williamson with art by Yasmine Putri, that will hit stores on October 1. And the tie-ins will continue to pummel shelves throughout the months to come, including in Titans #28, Superman #31, and Justice League Unlimited #12.
Then in The Flash #26, Mark Waid returns to the Scarlet Speedster for a tie-in issue, taking over from Si Spurrier, who is leaving with The Flash #25. Vasco Georgiev will provide art for that issue.
There are likely more tie-ins to come, and all will be revealed on the DC All In: What’s Next panel at SDCC. You can check out the October solicits for the issues, below, per PR from DC Comics.
