GCPD Officer Michaels

GCPD Officer Michaels was an undercover Officer within Arkham City.

Batman: Arkham City
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 Michaels.

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. Alongside his fellow officers Tom Miller and GCPD Officer Sanchez, he was held hostage by a five-man group of the Penguin's goons inside the torture chamber. After Batman neutralized the goons, he was ordered by Tom Miller to grab a weapon and begin patrol over the area to hole up the area.
