After Laurel Lance approached Cisco Ramon, he refitted her sister's sonic device to work in a collar, though more powerful; Cisco quadrupled the range of the sonic blast and tripled the resonance. In return, Laurel gave him a picture of him and the Black Canary together.
After Laurel's death, the Canary Cry was stolen by an orphaned teenager named Evelyn Sharp, who modified it so that she would be able to use it and so that it would produce deadlier sonic waves. Evelyn also began dressing up as Black Canary and using the device to help her in attempting kill anyone affiliated with H.I.V.E. in order to avenge her parents.
After Green Arrow talked her out of killing Ruvé Adams Evelyn dropped the Black Canary moniker and stopped using the Canary Cry. However, it's not clear if she's still in possession of it.
- Sonic scream: Like the Sonic device, the user can utilize the cry to generate a sonic wave. Laurel attaches it onto her neck to produce a high frequency. The wave has proved to be potent enough to shatter glass and powerful enough to blast an adult male several feet through the air. It appears to be activated by the wearer's shriek (making it look like a sonic scream).
- Canary Cry is the ability used by Black Canary in DC comic books and was showcased in various other media. Generally the Canary Cry is portrayed in the comics as initially a magically induced and later genetic ability that Black Canary was born with. However, after having her throat slit during a mission gone wrong with Green Arrow, Black Canary lost her meta-human ability due to the damage to her throat. Afterwards, Canary was given a technological sonic devise that could mimic her original abilities. Eventually, Black Canary's powers were restored after she was given access to a Lazarus Pit by Ra's al Ghul.
Behind the scenes
- The design of the Canary Cry weapon as a choker is a nod to Black Canary's classic costume.
