After getting clearance from his superiors, Ro-Nan contacted Admiral Kalxor and tried to negotiate a temporary ceasefire in order to deal with Gah Lak Tus, who was heading directly for the armada, but Kalxor refused to ally himself with Ro-Nan even as Kalxor's own science officer confirmed the truth. When the Gah Lak Tus swarm arrived and began to devour their armadas, Ro-Nan and Kalxor were forced to join forces in order to save their people.
Rick Jones, who had been observing them with a Watcher, joined in on the fight and helped them fight Gah Lak Tus but things quickly went downhill when the aftershock of Ultron's defeat on Earth-616 permanently shattered the entire space-time continuum and pulled Galactus to the Ultimate Universe, who ripped open a hole in reality and emerged into their universe.
While Gah Lak Tus and Galactus merged into a single being, Rick Jones helped Ro-Nan and Kalxor's forces retreat to planet 3.14 in the Raela system where a triage facility was set up. Unfortunately, Galactus followed them all to the planet and unleashed a swarm of tiny Gah Lak Tus drones upon the wounded, but thanks to Rick Jones and the Silver Searcher, Ro-Nan and his soldiers were able to return to the Kree flagship.
When Rick Jones noticed that the Kree flagship seemed to be making a run for it, he appeared before Ro-Nan demanding an explanation for the Admiral's actions. After formally introducing himself, Ro-Nan revealed that was going to destroy the Raelan sun using a doomsday device in order to destroy Gah Lak Tus and Galactus and that even if the first attempt failed he would continue destroying stars until the world-devourers were no more.
By the time Rick Jones pleaded for Ro-Nan to reconsider, he had already launched the weapon into the Raelan sun and ignited a massive supernova that Galactus consumed along with the billions of innocent people who were being burned alive by the explosion.
