"My currency is pain. I don't trust you to do the right thing unless I threaten to break your spine. My name is Black Canary, and if you want what's best for this city, you work for me now."
Dinah Lance is the Black Canary, a vigilante with the distinctive sonic scream superpower known as the Canary Cry, which she uses to fight crime with the Birds of Prey and Team Arrow. Her superpower is derived from a metagene that allows her to produce a powerful sonic attack capable of damaging, disorienting, and stunning anyone she uses it on. Her Canary Cry is powerful enough to be capable of shattering metals and even a human's skull if used directly on them.
