X-Men: Covert / Instinct / Ranged
Charles Francis Xavier was born the son of nuclear researcher Brian Xavier and his wife, Sharon. Following her husband’s accidental death, Sharon married Brian’s colleague, Kurt Marko. Cain, Kurt’s son by a previous marriage, came to live at the Xavier’s Westchester mansion shortly thereafter. A cruel and spiteful boy, he bullied his new stepbrother. As punishment, his father secretly beat him – and young Charles felt his sibling’s pain firsthand thanks to the emergence of his mutant telepathic powers. Following their mother’s death, a fire in the family home took Kurt’s life, leaving the stepbrothers alone.
