Harley Quinn is a character that appeared in LEGO Batman: The Videogame. In the break-out, she jumps onto The Joker's Helicopter and joins Joker's Group. She is in love with The Joker so much that her prison cell is decorated with posters of him. She is even a boss with him in To the Top of the Tower. She uses her acrobatics to help her evade capture at the end of Little Fun at the Big Top.
