I may change my character to ultimate cable. Tell me what you think of his origins, then I'll decide.
Ultimate Cable would be a direct desendant of Jean and scott born maybe 20 to 25 years in the future of the ultimate time line. During that time they realize that he has the T.O. virus. so they find a way to send him to the future. There he is rasied by apocalyse, after killing jean and scott, who with the help of xaiver had their minds transported to the future to watch over cable) who turns him into the ultimate weapon. Nate's whole body, except for his head, was infected by the T.O virus before apocalyse stopped it. He also can shoot the type of blasts that cycolps can out of his left eye the only thing on his face infected by the T.O virus.
The future apocalypse realizes that the heros of yesterday could possibly put a stop to his plans. So he sends his four horsemen led by Cable to the past. Cable's telekinetic and telepathic powers are greater than anything the X-men have ever faced so they lose the first round. During the fight Cable sees two people that he feels he knows. The X-men face off against the Horsemen again but this time cable betarys his team to find out more about Jean and Scott. All his life Cable felt he was doing the wrong thing and the X-men take him in and he finds out about his origins after Xavier looks through his memories and finds the turth.
