Dinah Drake

Dinah Drake, known undercover as Tina Boland, is a meta-human vigilante and a former police detective of the Central City Police Department. She was eventually recruited into the ranks of Team Arrow by Oliver Queen, who was searching for a successor to the Canary mantle. Later, on John Diggle's advice, she set her roots down in Star City by getting an apartment and a job in the Star City Police Department.

Early life
Dinah was born and raised in Central City, where she later joined the CCPD, becoming a detective, and specializing in undercover jobs. Her first undercover assignment was with the street gang called the Pilgrims, where she used bo-staff fighting.

Becoming a meta-human
In 2013, Dinah was an undercover cop going by the name Tina Boland in order to go after Sean Sonus. Sonus discovered that Tina was an undercover cop and he tortured her for 2 weeks. Sonus captured her partner Vincent Sobel and killed him. The S.T.A.R. Labs particle accelerator exploded subsequently, which give both Sonus and Dinah their powers. In her grief over Vincent's death she used a sonic scream, attacking Sonus.

She handed in her badge after her partner's funeral and went rogue becoming a vigilante all across America never settling down her roots. Although she always kept track of Sonus's movement.

Recruited in Team Arrow
In late 2016 to early 2017 knowing Sonus was in Hub City she indirectly got the attention of Team Arrow when Curtis showed them video footage of her fighting and using her sonic scream against the bad guys. Agreeing that she was perfect to be the next Canary. Curtis, Rene along with Oliver went to recruit her.

Personality
Before being subjected to inhumane torture and witnessing Vincent's death, Dinah was presumably a happy and carefree individual who cared deeply for the ones she loved. She even went far to legally change her name to keep her family safe as she went undercover in Sonus's gang. Dinah never revealed to anyone she was a meta-human following the particle accelerator's explosion and cut all ties with her former life the day following Vince's funeral.

Unable to understand herself and the powers she gained. Dinah started to travel all over the USA protecting those who needed. Still wired like a detective she kept track of Sonus's movement which paid off in killing him. However she admitted to Oliver that killing him didn't give her closure despite making sure that one less killer was on the street.
