Shortly after Marie's birth, her parents accepted Vought's offer to inject her with Compound V, subsequently transforming her into a Supe and granting her superhuman powers and abilities.
When Marie was 10, her powers of blood control manifested during her first period. Unable to control her powers, Marie accidentally killed both of her parents, leaving herself and her sister, Annabeth, the only survivors of the accident. As a result of this, Marie was separated from her sister and relocated to the Red River Institute.
Marie enrolled at Godolkin University to become a hero, trying to atone her tragic past and make her sister change the way she saw her.
Nothing works out as it might.
Marie and male Jordan have a one night stand, but she and female Jordan still have feelings for each other.
