This Harley is known to break the fourth wall on occasion and has a more positive and good-natured demeanor.
It should be noted that she’s never been affiliated with the Birds of Prey team before, expect for Huntress being the one to bring her to Amanda Waller.
Based off the Birds of Prey trailer, this is the Harley we’ll meet.
At one point after serving time in Arkham Asylum, she came back to Gotham with a whole new attitude that led her to become the landlord of her apartment building, joining a roller derby team, leading her own traveling sideshow, and all while remaining a Suicide Squad member.
