It is the 300-year anniversary for the town of Tremorton. Queen Vexus and her Cluster drones are again fighting Jenny. Vexus is beaten, but escapes, leaving her teleporter behind. Jenny accidentally ruins everybody's day and the ceremony by causing massive collateral damage to the town. Fed up with her, everyone in town, except for Brad, Tuck, and Sheldon, shuns her very presence and label her as nothing but an irreverent troublemaker, even her own mother, Dr. Wakeman. Jenny is upset by the townspeople's attitude and is overall fed up with being unappreciated by humans. While wandering the wreck site, Jenny stumbles onto the teleporter that Vexus used to escape and is transported to Cluster Prime. Cluster Prime is actually a robotic paradise where Jenny fits in and can be a normal teenager, even forming a group of friends who are robotic counterparts to her human friends, besides the friendly and popular Vega. Jenny soon learns that the Cluster people have been lied to through the government's propaganda; they are being told that Jenny is responsible for stealing the people's golden chips which grants them powers like fighting or flight. When Jenny sees that the Cluster citizens need help when there is trouble, she disguises herself with a helmet and Cluster flag so she can perform her heroic deeds without revealing herself to be the hated XJ-9. However, her deeds soon draw attention from Cluster forces loyal to Vexus, who put a bounty out on her head and attempt to lure her into a trap. Cluster forces led by Vexus and Smytus invade Earth and enslave the people; all the while, the citizens find themselves in an extremely ironic predicament when they beg for Jenny to come and save them and she doesn't show up because of their earlier ridicule, while Vexus also grows impatient as to why Jenny hasn't shown up to stop the invasion. Brad is determined to be a revolutionary leader and actually succeeds with childish pranks, while Dr. Wakeman, revealing herself to be a former member of the Skyway Patrol, takes Sheldon to confront Vexus. Jenny is soon exposed on Cluster Prime and is forced to flee from the Cluster authorities, but discovers that Vexus has stolen and hid the citizens' golden chips while scapegoating Jenny for the theft and that Vega is Vexus' daughter, making her Crown Princess of Cluster Prime. The chips are returned to the citizens, who learn the truth and realize Vexus had deceived them and call for her removal from the throne. Jenny is forced into a fight with Vexus with Vega coming in to save her. Vexus is forced to flee and Vega becomes queen, liberating Cluster Prime. Jenny returns to Earth, defeats Smytus, and is welcomed back with cheers.
