Somewhere in the depths of space, a United States space shuttle collided with a mysterious rock and the reminant energy created by the Scarlet Witch's recent alteration of reality. When the shuttle crashed to earth, a powerful mutant emerged and was subsequently detected by Emma Frost and Cerebro, in the process overloading Emma with psychic feedback. A team of X-Men were dispatched to the crash site, and the mutant attacked them upon arrival. After incapacitating Wolverine, the mutant absconded with Cyclops and Marvel Girl (Rachel Summers) to an old research facility used by Moira MacTaggart. The mutant seemed to have some knowledge of past X-Men and their history,in that he was able to recognize Cyclops but did not know later members such as Wolverine and mistook Marvel Girl for her mother, Jean Grey.
Using Sway's powers in combination with Marvel Girl's, the mutant began taunting the captured X-Men with images of the past. Meanwhile, Banshee uncovered the location of a secret tape with information about the new mutant but was killed by the Blackbird while delivering the tape to the X-Men. The Beast was, however, able to retrieve the tape, and the X-Men which contained revelations that the mutant, under the codename "Kid Vulcan" was part of a forgotten team of MacTaggart's students conscripted to help rescue a group of X-Men trapped by Krakoa, some years ago. The mutant, now using the code name "Vulcan," also revealed to Cyclops that he is his youngest brother.
