Nobody

Nobody is a masked vigilante who desires justice in the world.

2003 cartoon
Nobody was once a New York cop, who was on the verge of exposing Ruffington as a arms dealer to the black market. But Ruffington claimed he was harassing him and the police fired him. Angered at the loss of his life and his honor, Nobody strove to expose Ruffington.

In the aftermath of the Triceraton invasion, Nobody was on to Ruffington. While chasing one of Ruffington's trucks, he saved Leonardo and Michelangelo from being run over. He wasn't disturbed by their appearance and they worked together to investigate Ruffington, as he was in league with the Shredder, modifying Triceraton weaponry for more powerful uses. Nobody fought Ruffington in his helicopter and managed to get him handcuffed, just as the police arrived.

Nobody later joined the Justice Force.
