Judge 724

Judge 724 is a Robot who, as his name suggests, works as a judge, presumably at the New New York Court. He presided over the Donbot's trial, replacing Judge 723, who was shot almost immediately after entering the court house.

He is identified by a label on the front of his body, which reads 724.

Production
Judge 724 was first seen in the storyboard to the episode "The Silence of the Clamps".
