Liza

"He could've done anything to me...but he didn't."

-Liza talking about how sweet Hulk has been to her. Liza  is a singer who auditioned for Fish Mooney's Nightclub before meeting Hulk. Fish hired her because of her close resemblance to Carmine Falcone's deceased mother. She eventually discovers that she is a Meta-human and calls herself The Canary.

History
After auditioning for a job in Fish Mooney's territory, she was asked if she wanted to be powerful and respected like Fish, to which Liza agreed that she did. Afterward, when asked by Mooney to seduce her as the final part of the audition, Liza kissed her, albeit reluctantly, though she admits to Hulk on a stakeout that she liked kissing Fish. Later, when Mooney made the decision to have Liza and another singer fight to see who would get the position, Liza quickly beat the other girl into submission, earning her place at Mooney's side.

After Liza met Hulk, Fish started Liza's 'training'.

Over the course of several weeks, Fish taught Liza how to be seductive, as well as kind and motherly toward Carmine Falcone. Whenever Liza fails to meet Fish's expectations, Fish slaps her across the face in frustration.

Secret Weapon
Fish then began teaching Liza opera notes and chords. She disguised her to look exactly like Falcone's mother and planted her on the crime lord. Liza listened to opera with Falcone in the park, and began completing tasks for Fish and getting close to Falcone. Liza's bodyguard was later gunned down and she was hooded and kidnapped. Terrified, she found herself a hostage, but breathed a sigh of relief when she realized it was actually Fish who had her taken. Ms. Mooney had decided to make her move against Falcone, and Liza was her lever to Carmine's fall.

In exchange for Liza's safe return, Falcone would have to agree to leave Gotham permanently, and go live in the country. Falcone himself saw merit in this, but a combination of Victor Zsasz's unwillingness to let him give up, Hulk telling Carmine that he cares about Liza as well, as well as Penguin's revelation that Liza had been planted in Falcone's life by Mooney changed his mind.

Falcone arrives at the nightclub with Hulk, apparently resigned to the quiet life, but once he spoke to Liza himself, and saw from her reactions that Cobblepot's accusations were true, Zsasz and his henchwomen shot and killed Mooney's goons. Deploring the way he had been manipulated with the image of his mother, Falcone has Hulk escort Liza to his car, and takes her out of Gotham. Carmine then told Zsasz to take away Mooney and Butch Gilzean. Penguin was, however, given the opportunity for one last gloat, before his nemesis was dragged away.

Liza starts off as a shy and somewhat introverted club girl, mostly keeping her head down and accepting her lessons from Fish. But after Hulk comes in, she becomes a little more out going.
