Batgirl & Azrael (DC Universe)
As the adopted daughter of Gotham City's police commissioner, Barbara Gordon was raised in a household filled with cops and their stories. Barbara wanted nothing more than to follow in her father's footsteps, but the elder Gordon refused to allow it. As a jibe against her father, Barbara wore a ""Batgirl"" costume to a masquerade ball and wound up saving billionaire Bruce Wayne from a kidnapping attempt. Deciding that this was how she could serve the cause of justice, Barbara Gordon elected to keep her new costumed identity.
