Bio: St. Ives was the daughter of "Deadly" Ernest St. Ives, and used a magical sword "scarcely an atom's width thick," allegedly the only weapon capable of killing her father, to assist the Canadian superheroes Northstar and Aurora in combat with him. Although she apparently killed Deadly Ernest, he did return. There, the Flight member Puck used Nemesis's sword to fatally wound her father, who was then knocked in front of an oncoming subway train and apparently killed. Nemesis then explained her relation to the villain to the heroes and disintegrated. Her real name was never given, though it's safe to assume she shares the same last name as her father.
