Ship
Inside he learned of the Celestials and their technology and came to master it. He eventually brought the vessel to New York to use as a staging platform from which he launched his Four Horsemen's attack on the city. The original X-Factor was there to oppose him, but they were captured and brought on board. At the point the ship was still cloaked. While the mutants fought inside, Beast damaged some machinery that de-cloaked the ship and destroyed the navigation system, and the ship began to crash. Through a valiant effort, X-Factor managed to get the Ship to fall right along the river, and ironically, the only building it damaged was their own old headquarters. As the ship had a protective field that only allowed mutants to enter it, X-Factor took up residence in the ship.
Unfortunately, the 2,000 foot-long vessel was booby-trapped, but when the AI running the ship revealed itself and offered to help X-Factor, the traps were neutralized. The AI, which they called "Ship," had complete control over every part of its structure and could fashion rooms, weapons and vehicles as needed from various storehouses and parts it had. It was able to design and run training programs for X-Factor, as well as make living quarters and workshop areas for them. It wasn't a bad cook, either. Ship at times floated in the harbor, and actually took off to another world following a signal from the Celestials, whom X-Factor met as the Judged a distant world.
On that voyage Ship met one of his creators and learned more about his true nature; however, he opted to stay with his friends in X-Factor. Ship then returned to Earth and set down in lower Manhattan, where it dawrfed the Twin Towers and plunged a good chunk of the city into shadow for most of the day. Ship's AI was almost as sophisticated as a living being, as it was disrupted by Wipeout's touch during Genosha's raid on X-Factor (looking for Jenny Ransome). Soon after, however, Apocalypse sent his Dark Riders to attack X-Factor. While the invading force was rebuffed, they made off with Nathan Christopher Summers, and infected Ship with a techno-organic virus that overwrote its systems. Ship lost control of itself and in order to prevent more damage to the city it blasted off into space, where it exploded.
Fortunately, Ship was able to download its program into an energy matrix which protected the mutants long enough for them to reach the Blue Area of the Moon and the Inhumans, who were themselves under attack from Apocalypse. Soon, X-Factor found the Summers baby, who was himself infected with a T-O virus. Even after defeating Apocalypse, it seemed that there was no hope for the child. However, the time-travelling Askani appeared and offered to take Chris into the future, where he could be saved. Ship, whose matrix was already destabilizing, offered to spend the rest of his energy to protect Chris on the journey and to monitor his life signs. Upon arriving 2000 years later, Ship's matrix was nowhere to be found. It wasn't till about 16 years later when Blaquesmith sensed another presence inside young Nate Dayspring (as Chris Summers was known then) and removed a shining energy sphere that Nate called "Professor." Professor helped Nate survive and control his T-O infection, and taught him over time to "bodyslide," a means of teleportation.
Years later the Professor was incorporated into the space station Graymalkin. The station came with Cable (Nate's codename) back to our time.
