Fan Casting Crimson Cowl in Edgar Wright's Astonishing Ant-Man

Very little is known about the origins of the woman known as the Crimson Cowl. She has made reference to her father not approving of her lifestyle choice, though whether this comment was in relation to her criminal career or her orientation is unknown. The Crimson Cowl first appeared in Chicago performing a number of corporate espionage heists, only to encounter Ant-Man and Wasp when she attempted to infiltrate the Dynatechnics lab to obtain notes on a new material they were researching. Although forced to flee, she managed to complete her mission and teleported out with a flash drive containing the information. Following that altercation, the Cowl approached Nathan Garrett, a genius civil engineer who had racked up several large gambling debts. The Cowl agreed to pay off his debts in exchange for him creating several new technologies for her. Disobeying the Crimson Cowl's orders, Garrett donned the guise of the Black Knight in order to "field test" the equipment. This first outing brought him into conflict with Ant-Man and Wasp, and he was arrested. The Cowl arranged for Garrett to be freed on bail, but he insisted on going out again to "settle the score" with the Diminutive Duo. Once again, he was defeated and sent to jail. This time, however, the Cowl refused to post his bail, essentially firing him. Despite this setback, the Crimson Cowl used several of his technologies to form the second incarnation of the Lethal Legion, filling the ranks with various other criminals, including several that were on the original team. The Cowl's Legion faced off against the Avengers, but were defeated. Once again, however, the Cowl teleported out before she could be captured. She later freed several of the other Lethal Legionnaires using her teleportation cloak. The Crimson Cowl's current whereabouts are unknown.
