Bio: Marcy was an old friend of Hawkeye's from back in his carnival act days. After her father handed the business to her, the carnival was taken over by the Taskmaster. He was using the carnival as a training ground to take small-time hoods, train them and then rent them out to rich criminals as muscle. It was the perfect cover as Taskmaster blended in perfectly with the crowds at a carnival.
Marcy was able to sneak Hawkeye onto the carnival's mailing list and send a message for help. Hawkeye arrived and battled with the Taskmaster. Ant-Man (Scott Lang), who had taken his daughter Cassie to the carnival that day, joined in and together they were able to defeat Taskmaster and his gang. Unfortunately, Taskmaster was able to escape, but Marcy got her business back free and clear.
