Black Canary is best known for two things: being a tenacious martial artist and all-round athlete, and touting a devastating sonic scream known as the Canary Cry, which she can also use to glide.
She's appeared as a front-line member of both the Justice League and the Birds of Prey in the comics, but the character has become even more popular in recent years with her numerous iterations on The CW's TV series Arrow.
Needless to say, with the character's neat abilities, awesome look and considerable popularity with both comic and TV audiences, a feature film could be a real blast.
How Likely Is It?: It's pretty unlikely we'll get a Black Canary movie while Arrow is still on the air, for though the DCEU and Arrowverse versions of The Flash can co-exist, that's largely because the Justice League couldn't really exist without him, and the character is ludicrously popular.
Black Canary can wait, and though it might happen one day, fans will surely be waiting a while. 5/10
