Amy is an honest cop in the rampantly corrupt city of Bludhaven. Amy is assigned a rookie partner named Dick Grayson, secretly the vigilante known as Nightwing. She worked alongside him as he worked to rid the Bludhaven Police Department of corruption from the inside. At first, Amy assumes that Grayson, like almost every other cop in Bludhaven, is corrupt. But when he proves himself, she reveals that she and several other cops on the force are working to do the same. Her trust in Grayson growing, Amy introduces him to her family at a barbeque she invites him to. Amy would soon face danger outside of her duties as an officer, as when the assassin Deathstroke was paid to kill her. Nightwing struggled to protect her, eventually paying him off for Amy's life.
The group along with Grayson finally made progress following Chief Redhorn's murder. After which, Grayson protects his wife throughout Europe and gains the evidence Mary Redhorn had kept over the years. After this evidence was given to the feds, Amy was made Captain. Amy would once again find herself, as well as her family, being put in danger following this event, as when a group of corrupt Bludhaven officers attempted to gain revenge on her. Only for Nightwing to once again come to her aid, with her discovering his true identity through a shoulder wound. After learning the truth, she forced Grayson to turn in his badge as she strongly felt it interfered too much with his duties as an officer. After Nightwing left the city, she passed along information to Robin and Batgirl, when they moved to fill the void.
Amy was soon the first to discover Nightwing had been present at the death of Blockbuster, but hid this fact to protect him and concocted a story of Grayson having to work undercover at the time. When it finally seemed that Bludhaven had slowly started to heal, the society dropped Chemo on the city in retaliation for Nightwing's actions, costing Deathstroke his daughter Ravager. However Amy, as well as her family, escaped with Nightwing's aid.
