The plane she escaped in crashed and Whitney's face was badly scarred, but she was saved by the criminal Mordecai Midas and started to work for him. Midas is obsessed with gold and gave Whitney a golden mask to conceal her disfigured face. She also starts using the alias of "Madame Masque." Madame Masque meets Tony Stark (Iron Man's alter ego) and the latter shows concern for her despite her scarred face. She turns on Midas to save Stark, but leaves him because of her criminal past. Unable to forget her feelings, she assumes the identity of Krissy Longfellow, Stark's personal secretary. Both come to know each other's true identity and start a romantic relationship. Their happiness is short-lived as Count Nefaria is dying due to a failed attempt to gain superhuman powers. Whitney hires the Ani-Men to bring her father to her and then asks Stark to find a cure for her father. Count Nefaria threatens Stark, and he is forced to fight the Ani-Men as Iron Man. Whitney is unable to choose between her father and her lover, and when Nefaria's life-support system is damaged in the fight, she goes insane with guilt and grief. Whitney returns to the Nefaria family and regains her former position as leader. She resumes her vendetta against Iron Man and his friends. At one point, Frost becomes paranoid and starts to create physical copies of herself, known as bio-duplicates. One of her bio-duplicates, who is simply referred to as "Masque", turns on her creator and becomes an ally of the Avengers. She also creates robotic servants known as the Inner Guard and names them individually after notable historical traitors: Benedict, Brutus, Fawkes, Quisling, Monmouth (based on Benedict Arnold, Marcus Junius Brutus, Guy Fawkes, Vidkun Quisling, and the Duke of Monmouth) and two other, unnamed members. Benedict successfully recaptures Masque for Whitney. Masque tries to convince her the Avengers are benevolent and that she should reach out to Stark again, but Whitney is still too fearful to do so. She continues to be a criminal figure of importance, until her father returns from the dead, now with superhuman abilities, and destroys her base. She reluctantly assists the Avengers and the Thunderbolts against the Count, but she secretly plans to betray and destroy both sides, her increased paranoia causing her to believe that she can trust no one but herself, despite moments of doubt
