Jenna Duffy is a thief and con artist who joined Tweedledum and Tweedledee's Wonderland Gang as The Carpenter. She is highly skilled with tools and uses her abilities to pick locks and break into vaults.
She more recently was hired by Catwoman and the Gotham City Sirens to repair the damage to their headquarters. Because she is actually doing legal work, she demands extra money for everything she does for Catwoman. She was later hired by a man calling himself The Director who planned to kill Batman on camera. She was to design the set, but later discovered that she was to be killed off as well.
