A young boy who used his mutant powers to control his stepfather, making the man ‘kidnap him’, as his mother would not let Spencer do as he wishes. He presumably did this in order to get his stepfather to let him do whatever it was that he wanted to do. He then used his powers on Forge, trying to make him kill Mystique, however his control was broken when Mystique told Forge that she loved him. Spencer was then killed by Forge.
