The Canary Cry is the ability used by the superhero vigilante Black Canary in the DC Universe. Dinah Laurel Lance possesses a metagene that gives her a potent sonic scream, able to damage and stun foes or objects, to the point of shattering metal. In the Pre-Crisis Multiverse, Dinah's Canary Cry was the result of her being cursed by the criminal William Zard during her childhood.
The Canary Cry has been able to reach 300 decibels, which is enough to make a person's ears start bleeding even if they're not the attack target. During the time Dinah was without her actual Canary Cry, she carried round Canary Cry Bombs that would emit a similar sonic attack.
The Canary Cry was created by Dennis O'Neil and Dick Dillin, first appearing in Justice League of America #75 (1969).
