Batman y Superman: Colección Novelas Gráficas #43

In "null," the alien refugees Zelkot Iylar and the warring Volkir arrive on Earth, each with their own stakes in a desperate bid to alter the past. With The Flash drawn into Iylar’s timeline-hopping quest and Superman caught between preventing catastrophe and preserving history, the fate of Earth—and the course of time itself—hangs in the balance.

In the 25th century, Superman and Flash race across time to intercept Iylar, a Zelkot refugee trying to prevent an ancient alien war before it begins—each hero driven by a different vision for Earth’s future. As they track him through pivotal moments in history, the stakes grow higher, not just for the planet’s survival, but for the very timeline they’re trying to protect.

In "null," Superman's unintended release of Killer Frost sets off a chain of events that brings Firestorm back to life—reformed and ready to fight. As the two heroes confront the icy threat, Superman extends an invitation to Firestorm to join the Justice League of America, marking a pivotal moment in their shared mission.

In "null," Dick Grayson finds his day at the circus unraveling when he encounters Waldo the clown—only to realize Waldo doesn’t remember him. As Robin digs deeper, he uncovers a web of hypnotic control gripping the circus performers, with the shocking twist that Superman himself is under the same influence.
