Charles Xavier II was born to Mystique at the Addenbrooke's Hospital in Cambridge, England, following his father's death at the hands of a Phoenix Force-powered Cyclops. Soon after his delivery, Charles Xavier II was given away by his mother, who was impersonating Moira MacTaggert at the time, as she believed she was unfit to raise him.^[1]

• According to Raze, Charles Xavier II would be one-year-old by the time the Brotherhood attacked the X-Men in the past.^[2]
