Bluebird

Harper grew up in the Narrows, a rough part of Gotham City. Still in high school, she lives with and supports her younger brother, Cullen Row. Harper and Cullen had a rough upbringing which included an abusive father who also had a tendency to break things around the house. Harper developed a knack for fixing things while trying to keep the family electronics functional. This experience helped her get a job with the Gotham City as an electrical engineer.

One day when she and her brother were walking home alone, they were confronted by a group of local thugs who started beating her brother because he is gay. Harper attempted to defend Cullen with a tazer-styled weapon, but was unsuccessful and was disarmed. Batman appeared then and saved them, making a great impression on Harper and Cullen who had never been able to depend on anyone but each other.
