of the Zn'rx was found dead in the restroom and Noh-Varr becomes a suspect after attacking the Skrull subaltern Val-Korr, Nova calls in the Guardians of the Galaxy to investigate Emperor Stote's murder. During the "Judgment Day" storyline, Nova appears at Port Prometheus to protect the evacuees from the attackers at the time when Uranos the Undying was attacking. Powers and abilities Nova derives his powers from an energy source called the Nova Force which all Nova Corps Centurions wield. This energy was transferred to Rider by the Nova Centurion Rhomann Dey. The Nova Force affords Rider superhuman powers including flight, superhuman strength, speed, and durability, as well as the power to absorb energy directed against him and release it as gravimetric pulses and beams, either from specific parts of his body or from his entire body.

Nova's uniform is not only extremely malleable, but contains specific functions to aid Rider in his role as a Nova Corps Centurion. Among these features are an electromagnetic discharge that can nullify gravity and an interface to stargates that allow him to enter hyperspace, where he can move at velocities exceeding the speed of light. Rider can also alter the appearance and nature of his uniform to suit his needs. However, as Rider learns the hard way, the Nova Corps keeps a strict dress code. When he makes major cosmetic changes to his uniform after rejoining the New Warriors, Nova is summarily ordered to conform to standard. During Annihilation, Rider's uniform is altered and enhanced to house the Xandarian Worldmind as well as the entire Nova Force, which
