Tracey was a high-ranking officer in The Penguin's Gang, alongside Candy. She acted as an enforcer and was onboard the Final Offer, protecting Penguin's safe room from Batman. She also appeared at the Boiler Deck, where she oversaw the Boiler Deck's Death Matches.
Tracey had a Cockney style British accent. She had short blonde hair, and wore a short miniskirt with white/grey and an aqua tint to it. She had two earings, bracelets and a necklace that hung down to her ample cleavage. Tracey's lovely legs were accented with fishnet stockings and black high heals.
When Batman arrived, she served as the fight promoter who sent the Electrocutioner to fight him in the arena. After the Electrocutioner was taken down, Tracey sent some of Penguin's thugs to fight Batman in the Boiler Deck. Then she went to the casino while he was busy fighting. Tracey tried to send more men in after Batman in order to stop him. Tracey got a message for Batman from the Electrocutioner that claimed that he would be back.
Tracey was next seen in the casino and sent more thugs to finish Batman. Before having a conversation, Batman snuke up behind Tracey and she reached out for her wooden baseball bat to attack him. However, she was imprisoned by him in a cell in one of the rooms not long after trying to talk to Candy. Tracey protested her imprisonment due to her being claustorphobic.
Tracey somehow managed to escape for her cell and was next seen after Batman's fight with Deathstroke, with Candy and Penguin. She presumably spent the night with the Penguin.
It was assumed that Tracey later guit Penguin's gang or was killed for some reason, as she was never seen or heard from again in the later Arkham games.
