Biography
At the beginning of the game, Commissioner Gordon is driving a police truck holding a "special suspect" from Gotham City to Stryker's Island Penitentiary in Metropolis.

While en route, Commissioner Gordon receives word from Detective Renee Montoya that the Joker has broken into Wayne Tech. Commissioner Gordon dismisses this and orders Detective Bullock to look into the break-in, as he proceeds to Metropolis.

Once Commissioner Gordon arrives at Stryker's, he meets with an incarcerated Lex Luthor to ask for his assistance regarding a peculiar suspect apprehended at a lab owned by Luthor's colleague, Professor Ivo, whom he and Luthor were involved in the "Amazo" Project, an android capable of stealing powers from super heroes.

Commissioner Gordon promises Luthor that if he cooperates with the suspect, he would be released of a few decades from his imprisonment sentence. Lex Luthor agrees and the mysterious suspect is brought before him.

However, a security guard in his underwear alerts Commissioner Gordon that an intruder stole his uniform and is impersonating as the security guard present with the Rookie. The false security guard reveals herself as Lex Luthor's personal bodyguard, Mercy Graves.
