Josephine "Josie" Miller was the female assistant of the Joker.
History[]
Josie was a well known gun moll with a reputation for committing heinous crimes. Like most of the Joker's molls, it is unknown how and why she decided to work with the Clown Prince of Crime.
Josie takes part in the Joker's scheme to take over the Gotham National Bank and seems to enjoy herself a lot during all the criminal activities carried out by her boss. Although she looks rather innocent, she shows some true sadistic pleasure as she witnesses Robin's fight for his life after his capture at the hands of the Joker's robotic gang.
Josie play a part during the Joker's attempt to blackmail Bruce Wayne, Batman's alter ego, and even tries to make the millionaire marry her in order to get access to Bruce's riches. Although Batman and Robin have no formal evidence against the Joker and Josie, they manage to lure both criminals into a trap set up for them at the Gotham National Bank: as the Joker thinks his robotic henchmen could be reprogrammed by the Dynamic Duo, he orders them to kill the Caped Crusaders, thus becoming guilty of attempted murder with Josie as his willing accomplice.
After the Joker and his robots being defeated by the Dynamic Duo, Josie gets arrested. As she allows Batman to put the Batcuffs on her, she asks the Caped Crusader if he sees Bruce Wayne to tell him "It could have been fun." Batman promises to tell him and takes her away. She is then sent to prison for her crimes.
