- "You know, kid, not every day is gonna be like this. You just gotta hang in there."
- ―Black Canary to Cassandra Cain[src]
Dinah Lance, also known by her alias Black Canary, is the former resident chanteuse at the Black Mask Club and personal chauffeur for Roman Sionis. She is currently a member of the vigilante team Birds of Prey.
Losing her mother
While growing up, Dinah Lance's mother worked alongside the Gotham City Police Department, utilizing her metahuman ability to produce supersonic vibrations through screaming. At some point, however, she was killed and as a result, Dinah was left on her own on the streets of Gotham. As such, Lance harbored a resentment towards GCPD, and was reluctant to use her powers for good like her mother.
At one point, Lance began working as a singer in the club of crime lord Roman Sionis, which allowed her to move off of the streets. She entertained guests with her powerful performing abilities and repertoire, which included the song "It's a Man's Man's Man's World"; although as noted by Harley Quinn, no one ever seemed to pay attention to her performances.
While she did not aspire to anything more, after Sionis observed her using her powerful martial arts skills to ward off people attacking Harley Quinn, he decided to hire her as his new driver. In her role as his driver, Lance was approached by GCPD detective Renee Montoya to work as a mole, and was present when the pickpocket Cassandra Cain stole the Bertinelli Diamond from Sionis' right-hand man, Victor Zsasz.
Betrayal and siege at the Booby Trap
After witnessing Sionis intimidate and humiliate a woman whom he thought had laughed him, Lance became disillusioned with his whole operation, and resolved to work against him. Lance told Detective Montoya the location of the Bertinelli Diamond after Sionis sent her and Zsasz to retrieve it at the Booby Trap; however, unbeknownst to her, Zsasz discovered her betrayal and resolved to take her down once at the abandoned fun house.
After fighting off Zsasz with Quinn, Montoya, and Helena Bertinelli at the Booby Trap, she banded together with them to protect Cassandra Cain from Roman Sionis and his goons. It was towards the end of this fight that she used her sonic scream to knock out the remaining men, in order for Quinn and Huntress to chase down Sionis and Cain. 
Birds of Prey
After successfully defeating Sionis and saving Cain, she celebrated with the others at a Mexican restaurant before realizing that Quinn and Cain had stolen her car and made off with the diamond. Quinn returned the information stored within the diamond to Bertinelli, however, who then used her restored family's money to form the crime-fighting group known as the Birds of Prey.
Dinah seems to be a reluctant hero with a strong moral compass that guides her even when she is hesitant to help. While the death of her mother initially left her jaded about using her sonic scream and fighting crime, Lance tried to do good in her neighborhood and when she could. Despite her reservations, she still stands up for people when they cannot defend themselves, such as when Harley Quinn was heavily intoxicated and being kidnapped. Likewise, she seems to hold a fair amount of empathy for those who remind her of herself, as when she gave money to Cassandra Cain so she could avoid her stressful home environment. Despite her tendency to help, however, Lance still has a certain edge and easily sees through others' pretenses.
While working for Sionis, she was rather subdued and submissive in an effort to not cause much trouble; not minding when people ignored her performances or readily agreeing to be his driver. After witnessing his brutality against women, however, she realized that she could no longer simply stand by and found the courage within her to betray him.
Powers and abilities
- Sonic scream: Inheriting the meta-gene from her mother, Dinah can produce high-frequency shockwaves through her scream. Lance's sonic scream is highly potent in combat situations against numerous attackers, as she is capable of dispatching opponents by hurtling them backward through the air with concussive force alone. However, using this power for a prolonged period will exhaust her to the point of fainting. The very nadir of her ability is shattering glass, as seen when she performed on stage.
