Harley Quinn was a psychiatric resident of Arkham Asylum where she met the Joker who had been imprisoned. Harley Quinn became in love with her patient and conspired to break him out of jail, eventually becoming his lover and loyal sidekick.

Does Harley have “powers.”

Harley had no real powers to start with. However, her friend Poison Ivy gave her a “potion” after a failed attempt by the Joker to blow her up in a rocket. This enhanced her strength, speed, and agility, giving her immunity to toxins and a small healing factor (although it seems to vary — she was later shown in her solo series.

 In a matter of seconds to be able to heal from gunshot wounds once the bullet has been removed). Also, she is an impressive fighter, often using acrobatics as a young woman in whom she had trained. She uses a lot of weird and unique gadgets and weapons, like her traditional mallet, or a big pistol with a big cork in it. They both use surprising efficiency and end up being more useful than they would appear to be on the outside. Poison Ivy gave a weird brew to Harley, which increases her strength and speed. She’s not far beyond mortal man’s powers, but she has more physical strength than any Olympic athlete. She can put any man in just two punches or a kick to the floor. Her legs seem powerful, she succeeds in jumping very high – this without effort, coupled with her prodigious gymnastic skills, making her an incredibly acrobatic and “bouncy” fighting threat, adding to her momentum pendulous weapons like her hammer.

Furthermore, as part of her crimes, Harley is a master of disguise and often employs elaborate disguises. She has disguised herself on various occasions as a member of the entourage of a rocker, the columnist named Dr. Holly Chance and later took the identity of Dr. Jessica Seabron’s when she decided to become a therapist again.
