Origin

Harriet Pratt and her girlfriend, Lily, were small-time con artists. They would also do odd side jobs. One night they did a gig where they were animal themed hostesses. Harriet had donned a rabbit costume. When they were hiding from some of the aggressive hooting, they saw their employer pitching some new hypnosis inventions to some investors. They knew they would be a pretty penny and decided to steal them as soon as they left. While they were grabbing the merchandise, Mad Hatter walked in making them pause. Security came in soon after. Mad Hatter was able to escape but Harriet and Lily weren't so lucky. They put up a fight but Harriet got shot and Lily was struck in the back of the head. Both were then tossed in the river. When they washed up on shore, Mad hatter pulled Harriet out of the water. The icy water had kept her conscious, but her girlfriend had died. Jarvis helped nurse Harriet's gun wound. She remade her rabbit outfit into her villain suit. Mad Hatter fixed the tech he had stolen, and together they had become Mad Hatter and March Harriet.
