Originally, the Nova Corps was Xandar's space militia and exploration division. It consisted of over 500 soldiers ranging in rank from Corpsman up to Centurion and its leader, Centurion Nova Prime. The Corps also had a regiment of Syfon Warriors, of which Powerhouse was one. After the reformation of Xandar, the Nova Corps expanded its protective range to include the entire Andromeda Galaxy and Earth. They are also known as the Xandarian StarCorps. Queen Adora (in the role of Prime Commandant) has ultimate authority of the Nova Corps.
The source the Corps' power is called the Nova Force. This is a nearly limitless energy field generated by the a living supercomputer called the Xandarian Worldmind. The energy is then transmitted into the centurions at varying levels depending on their rank. The Worldmind contains the entire record of Xandarian history and civilization.
Recently the Nova Corps were assembled to face an unknown threat that had crossed the Kyln. Unfortunately, during the briefing, the Corps were taken by surprise by the attackers. Despite the fact that the every officer was granted full power by the Worldmind and their strong resistance, the entire Corps was decimated and in the ensuing destruction, Xandar was laid to waste. However, Richard Rider managed to survive and while looking for survivors, came upon the then-offline Xandarian Worldmind. The supercomputer told the last Centurion that if he died, all Xandarian culture and the entire Nova Force would be lost. Reluctantly, Rider let the Worldmind reside in him until it could find a new world to inhabit.
During the Secret Invasion, a new Nova Corps appeared to assist Richard Rider in his defense of the Project P.E.G.A.S.U.S. facility. The Worldmind had recruited them, having taken control of Rider's body while he was sleeping. Unfortunately, Worldmind began a mass recruiting drive, which Rider opposed, fearing of what could happen if they send untrained Novas into battle. Also, he had lobotomized Ego the Living Planet as a base for Nu-Xandar. When the Worldmind asked that Rider download the Nova Force into Nu Xandar, he hesitated. Worldmind, claiming that the Nova Force has taken its toll on Richards sanity, ordered the Corps to restrain him. Forcefully removing the Nova Force, Worldmind "deselects" Richard and returns him to Earth without his powers. Rider, with the help of Project P.E.G.A.S.U.S., learn that Worldmind was using a form of mind control, through use of subliminal messages and endorphins, to control the Corps and make them not want to leave.
When a war ignites between the Kree-led Inhumans and the Shi'ar, the Nova Corps stepped in to stop it. Unfortunately, they take massive casualties and the new Nova Prime, Malik Tarcel, was captured by the Shi'ar Imperial Guard. Richard Rider, who was stripped of his status by Worldmind, reclaimed the title of Nova Prime and decided to train the Corps as a probationary group.
When Rider charged the entire Nova Force in order to stop Thanos and subsequently went missing, the corps was left powerless and presumably disbanded. However, there was still hope in the form of former Black Nova Jesse Alexander's son, Sam Alexander.
Thought to be a covert black ops division within the police force, the Supernovas, or Black Novas, were in actuality an independent organization comprised of thieves and killers. They are named the Black Novas after their black helmets, which are designed to harness the full power of the Nova Force, as opposed to the traditional 'Gold Domes' (regular Novas, due to their gold helmets), which only grant partial access to the Nova Force based on rank. Sam Alexander is the only Supernova left.
- Uniforms: Made of unidentified materials that were highly resistant to damage, heat and cold including the extremes of outer space. The helmets contain advanced circuitry which enables Centurions to monitor and make radio transmissions. The helmets also include a malleable Xandarian alloy which could lower to cover the face by cybernetic command or via sensors in the uniform which could sense changes in pressure and atmosphere and activate automatically. Once activated, the uniform becomes airtight and the helmet connects to an oxygen supply concealed within the uniform which could last up to 6 hours. A Centurion's helmet also provides access to the Nova Prime spaceship and could see through its cloaking shield. When removed, the helmet would collapse into a cloth-like material.
- Other Devices: Xandarian equipment as needed.
- Source of Paraphernalia: All equipment and vehicles are of Xandarian design and manufacture.
Transportation: Flight under own power. Xandarian Starcruisers. Also one-man sky flyers.
Weapons: Other Xandarian weapons as needed.
- No special notes.
- The Corp imposes a strict dress code, as witnessed when Nova (Richard Rider) was ordered to change his uniform back to standard after he had altered it.
