Legion is Charles' autistic son. Professor X (Charles Xavier) and Gabrielle Haller had a relationship in the past. As a result, Gabrielle had a child she named David Charles. Charles Xavier was unaware of the child after their relationship had ended. When David turned ten, his mutant abilities first began to manifest. David also developed split personalities. Each personality could control different powers. As David grew older, his condition grew worse. When David was in his late teens, Gabrielle finally sought out Charles and asked for his help with their son. After some time together, Charles was able to restore David's core persona, alleviating the inner struggle among the different personalities.
