Suicide Squad's Harley Quinn: Everything You Need to Know

Harley Quinn is making her big-screen debut in Warner Bros' Suicide Squad. Despite being created back in 1993, many see her as simply the Joker's girlfriend. Since making the jump from Batman: The Animated Series to monthly comics, Harley has come a long way. Here's everything you need to know about her.

Harleen Quinzel had a pretty typical childhood. At a young age, she became the victim of bullying by some mean girls. She decided to take matters into her own hands after being inspired by Wonder Woman.

Putting on a Halloween costume, she took care of the bullies. She got in a little trouble and promised something like this wouldn't happen again.

As a teenager, she earned a gymnastics scholarship at Gotham State University. She used this opportunity to pursue a degree in psychology.

When she struggled with her grades, she found other ways to get by.

She managed to get a job interning as a psychiatrist at Arkham Asylum. She admitted she had an attraction to extreme personalities, finding them exciting and challenging with a hint of glamour.

Upon first laying eyes on the Joker, it was apparent she was smitten.

The attraction may have been mutual. Joker managed to place a flower and note in Harley's office, inviting her to see him.

Joker seemed to be flirting and even offered to tell her his secrets. He told her a story about how his father beat him. He also mentioned being abused by people like Batman.

After Joker managed to escape and was returned to Arkham after being beaten, Harley snapped.

She rushed out to the store, stole weapons and supplies, and returned to Arkham, reborn as Harley Quinn.

Later it was shown how Joker further helped in Harley's transformation. Joker brought her to the chemical plant where he went through his change.

Without giving her a choice, he pushed her in and her skin and hair were altered.

Simply put, Harley was in an abusive relationship with Joker. When she tried making some special time with him, he grabbed her by the nose and threw her out.

When he found out she captured Batman and feared the other villains would chide him for being the guy whose girlfriend killed Batman, his first reaction was to smack her. He even knocked her out the window of a four-story building. Harley felt it was her fault and she was to blame.

Eventually Harley was able to move away from the Joker. He often was locked up or simply did his own thing. In a recent encounter, she made it clear where she stands with him. When using his mind games on her, things quickly turned violent.

Harley let Joker know she was tired of the physical and emotional fighting and that she was done with him.

Harley spends time with Poison Ivy and other friends, but is also forced to take part in missions with the Suicide Squad. It's never clear what Harley may do next. Whether she's on her own or working with others, you can bet she'll manage to liven things up.
