to reunite with Figure Four, but was killed by a doll bomb planted by Nova, who had survived decapitation by having a second brain-ship installed into his abdomen. However, Nova then transports Alita's remains to Tiphares and resurrects her with a new "Imaginos Body" with a neuronal accelerator which gives her unlimited potential. In the original series, Nova guides Alita to confront the Melchizedek – the supercomputer ruler of Tiphares – about the truth of Tiphares and Ketheres' history. Nova provokes Melchizedek too far, causing it to go haywire and self-destruct. To save Tiphares from falling and colliding with Scrapyard below, Alita takes an Imaginos trigger given by Nova and sacrificed herself to secure the Sky Hook by fusing with it. Nova immediately regrets giving Alita the trigger, as he cannot bear being saved by her selflessness, and goes completely mad.

However, it is later revealed that Nova has already invented the Stereotomy process, which allows him to create reincarnations of himself, making him effectively an immortal presence. Going into space with new and old companions alike, to look for her lost friend Lou Collins and to find out more about her forgotten past, Alita is caught up in an interplanetary struggle between the major powers of the colonized solar system. Along the way, she forms an alliance with three of the Alita Replicas who have now begun to think for themselves, an unsavory superhacker, and Nova himself when she enters the Zenith of Things Tournament (Z.O.T.T.), a fighting competition held every ten years. Later on, Super Nova (one of reborn versions of Nova) reveals that the Alita in the story is actually a replica
