"Harriet Pratt might have spent her whole life as a small-time grifter and swindler if she hadn’t been recruited to join the Mad Hatter’s Wonderland Gang. Now she gets to dress up like a rabbit and commit crimes with a way higher profile. She may not have any special powers of her own, but this hare-raising villain is still a crack shot with a tommy gun!" —LEGO.com
Harriet Pratt was a small-time grifter and part-time "escort" operating out of Gotham City before she was enlisted by Tweedledum and Tweedledee to join their Wonderland Gang. She was one of the first members besides the brainwashed Mad Hatter, and functions as the group's "March Hare."
