GCPD Officer Best 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 GCPD Officer Best.
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. When Batman arrived at the Gladiator Pit inside Cyrus Pinkney's Institute Natural History (Penguin's hideout within Arkham City), Best, clutching his chest in pain, weakly tries to beg for Batman's help. Unfortunately for him, Batman wasn't able to get the chance to help him as the Penguin shot him in the back with one of his umbrellas immediately afterward, killing him. Batman managed to avenge him after apprehending the Penguin.
- Ironically enough, Best was the only member of the squad to die during their undercover operation.
