Superman: New Krypton #1

In the wake of Superman’s battle with Atlas, Jimmy Olsen follows a mysterious lead that pulls him into a hidden past tied to Jonathan Drew and the enigmatic Codename: Assassin. As the trail unfolds through Cadmus, a dying Dubbilex, and the forgotten legacy of the Guardian’s clone, Jimmy must piece together a truth buried beneath secrets and loss—before the past catches up with him.

In "The Worst Night of His Life," Jimmy Olsen reconnects with a man claiming to be his old friend Jim Harper—only to learn the truth behind the man's origins and the tragic past that haunts him. Flashbacks reveal Harper’s encounter with the alien Tellus, the death of the original Jim Harper, and a chilling discovery at a Cadmus cloning facility, where he faced clones of himself and Paul Kirk. Though he destroyed the others, a single female clone—Gwendoline—was spared, and now Harper must decide what comes next.

In the wake of Jonathan Kent’s funeral, Superman grapples with grief and rage, his thoughts turning to Brainiac—captured and under interrogation by a mysterious general. Meanwhile, Clark reconnects with his extended family in the newly expanded Kandor, meeting Zor-El and Alura, while Lois finds quiet solace at her father’s grave, sharing a moment with Lucy. As secrets unravel, a shocking revelation ties the general to Lois and Lucy’s past—and even Lex Luthor, imprisoned and scheming, is drawn into a new game.

In "Strange Meetings and Chance Encounters," Superman navigates the delicate balance between Earth's leaders and the newly arrived Kryptonians, from Kandor, as he prepares to introduce them to Metropolis. With the Justice Society of America, Wonder Woman, and even a cameo from Lois Lane and Jimmy Olsen watching closely, the moment takes an unexpected turn when a fireball crashes into the city—revealing the unmistakable presence of Doomsday.

In "Beyond Doomsday," Superman faces his most brutal trial yet as Doomsday's rampage escalates—this time with Supergirl, her parents Zor-El and Alura, and the Kandorian survivors joining the fight. With General Lane and Lex Luthor pressing forward on Earth, and Zod’s former soldiers plotting to free their leader from the Phantom Zone, the battle for Earth’s fate reaches a breaking point on the moon, where the Kandorians unite to end Doomsday once and for all.
