Donna returns to the now-barren New Cronus where she shares a joyful reunion with Wonder Woman. Donna, charged with the guardianship of the Universe Orb containing the Multiverse Chronicles collected by Harbinger, makes the startling discovery that an impending doom is facing the DC Universe, a doom she cannot avert alone. Leaving Nightwing behind on Earth, Donna brings several heroes to New Cronus, including Animal Man; Cyborg; Firestorm; Herald; Bumblebee; Red Tornado; Shift; Green Lanterns Alan Scott, Kyle Rayner, and Kilowog; Jade; Starfire; Supergirl and Captain Marvel Junior (in Outsiders 30). The heroes confront a mysterious and menacing rip in space caused by Alexander Luthor, Jr. (as a part of his plan), which has sparked an intergalactic war. Donna's team contributes to the resolution of the conflict, but things take a dangerous turn when Alexander uses the inter-dimensional tear to recreate Earth-Two and, later, the Multiverse. Donna, along with Kyle Rayner (now called Ion), leads the team to attack Alexander Luthor through his space rift, giving Nightwing, Superboy, and Wonder Girl the time needed to destroy Alexander's device, and save the two Supermen and Wonder Woman from being merged with their Earth-Three counterparts. Though most of the team vanishes when they attempt to leave via the portal opened by Mal Duncan and Adam Strange, she returns to Earth shortly after the Battle of Metropolis, and provides a "junior red-sun eater" to the Green Lantern Corps in which to imprison Superboy-Prime at the end of the battle on Mogo.
