Harley Quinn

Harley Quinn started her life as a normal teenage girl, she had a normal life with a mother and a father and two brothers and she had a passion for reading, even if she did have a few hobbies outside the norm such as lighting the corpses of dead animals on fire, she was still a pretty normal girl at first. As she grew up she knew right away what she wanted to do with her life, she wanted to study the minds of serial killers. Due to odd obsession with the criminal mind she found herself distanced from many of her class mates but there was one who stood out to her, Berny Bash. Now Berny, he was a troubled boy and at the Halloween party where they met he asked Harley, “If you could kill anyone in this room, who would it be?” and Harley thought long and hard and she decided it would be Bonnie- the popular girl in school her turned Harley’s life into a living hell. A few days later Berny showed his love for Harley by throwing Bonnie out of his car into oncoming traffic, killing her. Harley thought it was the most romantic gesture ever and as Berny was sentenced to juvenile detention Harley shed her first tear over heartache. She snuck into his room and stole a memento to remember him by, a stuffed beaver he kept by his bed. 
Berny and Harley wrote back and forth for a while, while Harley moved on with her life but eventually Berny died in prison, stabbed to death over a side of mash potatoes. Harley was saddened by Berny’s death but time moved on as it always did and Harley graduated from Gotham University and went to work in one of the many hospitals of Gotham. However, Harley’s true passion remained the criminal mind and because of this she decided to take a job at Arkham Asylum. She considered the broken and unfixable patients of Arkham Asylum her ultimate challenge and after studying them through the cameras, she decided that she couldn’t get close to people that were this paranoid unless she became one of them. Harley wanted to conduct her own experiment, so she dyed her hair blue and red and had the warden admit her as a patient. While plenty of the prisoners wanted to talk to Harley, one inmate was on the top of her list, the exiled prince of Gotham, the Joker. He knew right away who she was and the two of them fell in love, well Harley fell in love with the Joker, while he remained undecided. Meanwhile, an inmate killed the warden which sparked a new warden to start an investigation, where he found out about Harley’s experiment. She was dubbed irresponsible, certifiably insane and a risk to those around her, because of this the guards tried to escort her out of the building but she had no plans to leave without the love of her life. Harley took the guards gun and broke the two of them out of the Asylum. The two of them spent some time together and the joker showed his love for her in his own special way, by throwing her into the vat that bleached his own skin, bleaching her skin. This gave her that pasty pail appearance that she’d become known for. 
As time went on Harley began to realise what the Joker wanted from his girl and she was willing to give him anything, anything he wanted she was willing to do but what he really liked was the ditz, so she became his ditz and started calling him mister J. One day the joker became bored of Harley and he sent her out on her own. While Harley was torn up at first it worked out for her as she was able to find herself and become her own person.
