In one of the first trailers for Suicide Squad, Harley Quinn proudly proclaims that she is "known to be quite vexing," and with one look at her, it's not hard to see why. With her pale white skin, her bleached hair, and her wild eyes, Harley certainly doesn't look like the kind of woman you want to mess with. In other trailers, she's seen shooting a gun and wielding a bat not unlike Beyoncé's Hot Sauce, but as for powers, like El Diablo's fire or Killer Croc's crocodile teeth, Harley seems lacking. Harley Quinn's powers in Suicide Squad might be a bit less clear than that of the other characters, but that doesn't mean they don't exist.
As a fairly new comic book character, Harley Quinn's powers aren't really well known, or set in stone, for that matter. Her most defining superpower is, arguably, her insanity — I mean, a person has got to be insane to keep up with The Joker, right? But her mental state isn't her only supervillain asset. Since her inception in 1992, Harley Quinn has acquired superhuman strength, and agility. She is also known for being one of the smarter characters out there, starting off as a psychiatrist before being turned into a supervillain in the Batman world.
Harley's mental powers are her biggest asset in Suicide Squad, as actor Margot Robbie revealed during interviews at Comic-Con. "She's definitely one of the more unpredictable members of the squad," she told reporters backstage, via LA Times . "She's always picking someone to be dissecting and playing off and messing with." But Harley's mind isn't the only dangerous feature she has. Like in the comics, Robbie's version of Harley was trained as a gymnast when she was younger, accounting for her flexibility and agility in battle. "She used to be a gymnast — that's her skill set when fighting," Robbie told Vanity Fair . (It also explains those brief clips of Harley doing acrobatics in her jail cell shown in various trailers.)
In some comics, Harley Quinn also had the power to heal herself thanks to her relationship with Poison Ivy. The other famous Batman villain gave her a potion that made her immune to poisons and gave her enhanced healing powers. However, it's unclear whether or not Harley will have this superpower when we meet her in Suicide Squad. Poison Ivy is, as far as we know, not appearing in the film, which means that Harley's invincibility might be a story for another day.
Healing power or not, you don't want to mess with this crazy girl, that's for sure.
