Mara Grace was enrolled in a public academy where future Legionnaire Lyle Norg (Invisible Kid) and Jacques Foccart (Invisible Kid II) were her classmates. Mara's mutant pheromone power emerged in school, turning her skin color. She quickly learned that she could make any boy in the academy unconditionally love her and do anything she asked. She donned a dominatrix costume and began calling herself 'Charma' to reflect her power over men. Lyle, a biochemical genius, eventually figured out how to defeat her by creating a protective 'second skin' for himself that blocked out pheromones.
