Info Black Canary:
At her Golden Age debut, Black Canary was the alter ego of Dinah Drake and participated in crime-fighting adventures with her love interest (and eventual husband), Gotham City detective Larry Lance. Initially, the character was a hand-to-hand fighter without superpowers who often posed as a criminal to infiltrate criminal gangs. Later stories depicted her as a world-class martial artist with a superpower: the "Canary Cry", a high-powered sonic scream which could shatter objects and incapacitate enemies. When DC Comics adjusted its continuity, Black Canary was established as two separate entities: mother and daughter, Dinah Drake and Dinah Laurel Lance. Stories since the Silver Age have focused on the younger Black Canary, ascribing her superhuman abilities to a genetic mutation. In 2011, DC Comics again reset its continuity, establishing Black Canary as a singular super-powered heroine and former Team 7 agent, Dinah Lance (née Drake).
