Mother of Gotham, and the Jokers Queen

Harley left the joker after falling for dead shot. the break up sent Joker into depression. he became blinded with hate, loneliness, hurt, betrayal, and heartbreak. He was so blinded that he had not seen the rising of a new criminal that has now become greater than himself.......

Mel Mountbatten, short for Melpomene, was once a normal happily married woman. That was untill her husban got greedy for her money. So he attempted to kill her by tossing her into a chemical bath. Instead of killing her; it had changed her DNA. With a new body and a sharper mind she took on the a new life of crime and grew to be one of the most feared and respected, even suppressing the joker himeself.
