9. Arkham Asylum
The fact that critically acclaimed video game Batman: Arkham Asylum was set in said asylum obviously resulted in Harley Quinn getting a very stylised look, with a nurse's costume incorporated into her sexy appearance. This one emphasises the character's cleavage, but updated Harley in a way which could easily be brought to life in convincing fashion on the big screen. Even the white painted face and domino mask work really well in this instance. Interestingly, this version left Harley with just regular blonde hair, dropping the red and black which has often been added to it after the character lost her headpiece in the comic books. Perhaps that will translate into live-action a little better, and, as she's among those taken to Belle Reve by Amanda Waller to be part of the Suicide Squad, a prison uniform could potentially replace the nurse's outfit that Harley can be seen wearing above.
