Dinah Lance a.ka Black Canary is a former resident chanteuse at the Black Mask Club and personal chauffeur for Gotham City crime lord Roman Sionis. Canary is also a powerful metahuman, inheriting her distinctive sonic scream ability from her late mother. After becoming disillusioned with Sionis due to his cruelty towards others, she eventually fought back against him with the assistance of Harley Quinn, Huntress, and GCPD detective Renee Montoya in order to protect Cassandra Cain when the latter stole the Bertinelli Diamond from him.
