With all their missions carried out, the duo head back to Kerwan where Qwark goes over a plan to infiltrate the factory Drek Quartu and take him. While Elaris, the support person of the Ranger and Clank think they should think of a plan, the rest decide to go full-on assault. They infiltrate the factory and, after defeating a giant Ms. Zurkon, Ratchet, Clank, and Cora discover the plan of Drek: he plans to use a superweapon called the station Deplanetizer destroy worlds and take their pieces to make Drek own perfect world. They follow the gun to Novalis and Qwark penetrates only trying to “talk” Drek of his madness. Rangers suspect something is wrong and go on the offensive. Ratchet infiltrates the station while Clank fights Victor on their mother ship, the Phoenix, defeat if the use of the sprinkler system. Ratchet tries to close the gun, but Drek incapacitating him. While his guards escorting a rescue capsule, Ratchet finds Qwark betrayed them switch sides to join the Blarg because of his jealousy to the heroism of Ratchet. Ratchet is run away and Novalis is destroyed Qwark giving second thoughts.
Although no one was killed in other attacks, five planets are destroyed. Ratchet, however, be a Ranger leaves and returns to Veldin. Clank convinces him that only they can stop Drek, Qwark and Nefarious. They learn that their next target is Umbris, which has a single core. And it gets worse: there is a rare planetary convergence in place. If Umbris is destroyed, its solar system to match. They therefore include the truth: Nefarious manipulates Drek by destroying worlds for his own gain. Elaris sends the duo Kalebo III, house Gadgetron, acquire a Holo-Guise so they can sneak aboard Deplanitizer. With the Holo-Quise in their possession Elaris reworked so they can look like Qwark and passes over the plan: Ratchet and Clank will infiltrate the weapon and take its nuclear power source while the rest of power Rangers their tractor beams to move the weapon on the orbit of Umbris.
