5) Black Canary
The Black Canary is a character who TV audiences have seen quite a lot of through Arrow, with its two separate versions of the character in the Lance sisters. However, they are both quite different from the comics’ iteration, so DC should definitely look at bringing her into the movies as well.
[zergpaid]One of DC’s oldest female heroes, Dinah Lance is also the longest-serving member of the Birds of Prey. So if the team does make an appearance in the movie in some form, it can be expected that Black Canary will turn up as well. An expert martial artist with the ability to emit a super-sonic scream, she could easily hold her own alongside the likes of Harley Quinn.
