James Gordon (Earth-4678)

"I keep asking myself why I didn't bring him in. And I now know, the truth is I let him go because of you. Because you believe in him. I don't know... They put me in charge of a station full of rotten cops. And I can't change them - any more than I can change this damn city... Or at least that's what I used to think. But maybe, maybe I can give them something to believe in. Maybe HE can give them something to believe in."

- James Gordon

Police Commissioner James Gordon dedicated his career to cleaning up the corruption in the Gotham City Police Department, a goal he came a long way toward accomplishing. Gordon was equally tough on crime, and in the pursuit of making Gotham City safe for all its citizens, he forged an uneasy alliance with Gotham's other top crime fighter, the mysterious vigilante known as Batman.

With Batman's help, Gordon had a successful war on crime for over a decade, turning Gotham from a city where getting mugged was a part of daily life to a city where everyone felt safe. As the Knightfall Protocol began, Gordon retired from his job and became Mayor of Gotham.
