GCPD Officer Jon Forrester was an undercover Officer within Arkham City.
Batman: Arkham CityEdit
When Arkham City was developed, Commissioner James Gordon, due to his attempts to question Sharp about Arkham City either being ignored directly or placed in red tape, sent ten members of the 13th precinct to go undercover into Arkham City, one of them being Forrester.
Unfortunately, as soon as he and his fellow squad arrived in Arkham City, they were exposed via an information leak and captured by the Penguin's men. Shortly after the Penguin murdered fellow police officer Best, Penguin's right hand man, Sickle, carried Forrester by the neck with him facing Batman, while Penguin attempted to taunt him, and later have various psychopaths waiting for initiation try to kill Batman, and later revealing a Titan-laced henchman. Sickle and Penguin escaped in the chaos with Forrester in tow, and then the Penguin began to freeze Forrester's fellow officers Strickland and Whitman with Mr. Freeze's stolen Ice Gun. Forrester attempted to escape Penguin, but before he could reach the exit, one of Penguin's blasts hit him while Batman was watching. After Penguin told Batman to "enjoy his Copsicle," Batman carefully rescued Forrester from his icy prison while avoiding shattering the unstable ice below them. After Forrester explained what happened to Strickland and Whitman before him, he was left to thaw out.
After Batman killed Grundy and brought Penguin over to Mr. Freeze to lock him up in the cabinet designed for Bruce Wayne, Forrester now understands that Penguin was not a joke anymore that the sqwaky villain is truly insane!
