Harley Quinn

How Harley Quinn joined the Tourney
Before her descent into madness, Dr. Harleen Quinzel was a promising psychiatrist assigned to Arkham Asylum, Gotham's home for the criminally insane. But after meeting Mewtwo, the Genetic Pokémon became obsessed with the crazed criminal's warped mind. Sensing opportunity, the Joker manipulated her, driving his therapist so mad that he was able to control her. Harleen fell in love with the Pokémon, broke it out of Arkham and devoted her life to making it happy and spreading his bloody brand of mayhem. Athletic, agile and dangerously unpredictable in a fight, Harley Quinn is a formidable opponent in her own right. She is willing to do anything in order to further the Genetic Pokémon's goals—no matter the cost to anyone else or even herself. Her energetic, affable and animated personality is enough to make almost anyone drop their guard—a mistake that could easily cost them their life. Deranged and psychotic, Harley Quinn is the poster girl for chaos' terrifying allure, and she entered the Smash Bros. Tourney to find the Joker.
