The Hollywood Reporter announced DC K.O., a five-issue event series by writers Scott Snyder (Absolute Batman) and Joshua Williamson (Superman), with art by Javi Fernández (Batman & Robin, King Spawn). DC K.O. debuts in early 2026 and features 36 fighters who are recruited for a tournament of champions as Earth is transformed into a massive five-level fighting arena. As heroes win, they move up in the brackets, and each descending stage tests the heroes in brutal and symbolic ways. The goal is to generate enough Omega Energy to rival Darkseid and crown a new King Omega, a celestial being toward whom the universe bends.

“DC K.O. is a knock-down, drag-out fight between all your favorite DC super heroes in a cosmic tournament to save the universe from Darkseid,” Snyder said in a statement.

Since this is the Summer of Superman, and James Gunn’s Superman film is now in theaters, it’s only right that the Man of Steel is the main protagonist of DC K.O. Snyder spoke about what made Superman the right hero to focus the event’s story on.

“I wanted to tell a story about Superman looking into his own heart of darkness,” he said. “It’s a very personal story wrapped in nine layers of candy exploding in your face.”

“Each level is a new challenge,” stated Williamson. “And the tournament will reveal unexpected heroes—some you won’t believe will go really far in the fights.”
