Batman: Arkham Knight - 10 Awesome Villains Who'll Steal The Show

10. Harley Quinn

Harley Quinn's role in Arkham Knight is going to be very interesting - not only is she confirmed as appearing as a foe in the game, she also has her own challenge maps (available through pre-ordering the game), making her a playable character for the first time in the series. Does this mean Harley will see reason and join Batman's fight then? Unlikely. An add-on to Arkham City (entitled Harley Quinn's Revenge) saw Batman dealing with a mourning Harley who was hellbent on avenging the recently deceased Joker; despite saving her life at the end of the add-on, Harley still blames Batman for his role in the Joker's death. This storyline is definitely going to be key going forward in the Arkham series. Even if the Joker doesn't actually appear, he will continue to have a haunting role on the series and even Batman will struggle to accept that he really is dead - Harley Quinn's extended mourning period will definitely cause trouble for the Dark Knight. Harley's larger-than-life demeanour and obsessive nature (backed by the incredible vocal talents of Tara Strong) have ensured she is a vital part of Batman's rogue gallery; Rocksteady will definitely give her a key role in their farewell to the series.
