In the Convergence crossover, when the alternate Brainiac miniaturized the universe of the New Earth, Ryan appears to be alive and confronts Ray Palmer, who was battling the Angor universe's Barracuda. Ryan reveals that after his death, his consciousness had survived in the universe where the Atoms' masses are shifted to whenever they change size. He later returns to the realm of the living after appropriating the flesh from Ray's severed hand to create a new body for himself. After Barracuda is defeated, the two Atoms work together to defeat Deathstroke, avenging Ryan's murder.
