Blown apart in an attack by the Luphomoid Zorr, Xandar is saved from complete destruction by the timely intervention of Uatu the Watcher, who assists the Xandarians in creating a network of interconnected domed cities out of the largest remaining pieces of the planet. The planet is later nearly destroyed by the Skrulls. Later still, Nebula destroyed the planet and the Nova Corps. The Nova Corps were resurrected by Richard Rider who used the Nova Force power to reboot the Xandarian Worldmind computer which proceeded to clone the dead Xandarians including Queen Adora. The war-torn planet is, once again, completely destroyed, and the Nova Corps decimated at the hands of Annihilus. Rider stands as the last surviving Nova Corps member following the massacre. The collective hive mind which resided in Xandar's core, an entity known as the Xandarian Worldmind, also survived and is now housed within Rider's newly modified uniform, which has also been enhanced to assist him in containing the full measure of the Nova Force. For a short time, Ego the Living Planet became a temporary home for the corps, known as "New Xandar." This was short lived as it was revealed Ego's intelligence was gradually returning and was attempting to corrupt the newly re-formed Nova Corps.
