In present-day stories beginning in the 1990s, it was explained that Mason had been bestowed her powers by the wizard Merlin in order to produce a champion to aid the Allied Forces during World War II. She and several other heroes of that era volunteered to enter suspended animated sleep at a classified vault to be summoned again when the world needed them. During the "Shroud Wars" storyline of "Femforce", these heroes were awakened and were initially referred to as the "Vault Champions".
