Ever since Black Canary showed up on Arrow in the form of Sara Lance, we've always wondered when the character would get her "cry" abilities from the comics. Sara had a device that could emit loud screeching sounds that could break glass and disorient enemies, but nothing compared to the real thing.
Well, that could all change in The Flash episode "All Star Team Up." From what we can tell from the latest promo images, Joe and Cisco will make their way to Starling City in hopes to find the dirty deeds on Dr. Harrison Wells. There, the group will meet the likes of Laurel Lance, who will end up getting a device from Cisco that is designed to give the character her long overdue canary cry.
The device is something Laurel will wear around her neck, possibly to increase the wave of her voice. We're just speculating here because we have no idea how it works. However, we've always suspected that this would be the way Black Canary would get her canary cry.
