Frost called the child Whitney and raised her as his own. As a young adult, Whitney was a debutante and socialite, and became engaged to politician Roger Vane. Following the Frosts' deaths, Count Nefaria approached Whitney and revealed her true parentage, as he wishes for her to inherit his position as head of the Maggia, a Mafia-like organization based on the East Coast of the United States. Whitney at first refused, but when she tells Roger about her father, Roger ends their relationship out of fear that her connections to a known criminal would hamper his political prospects. Heartbroken, Whitney accepted her father's offer to join the Maggia and was trained by the Count in strategy, criminal activities, and combat. She turned out to be a brilliant student and when her father is imprisoned, she becomes the new "Big M", the leader of the Nefaria family of the Maggia. Her role as Big M brought her into conflict with Iron Man, an old enemy of Count Nefaria.
