James Nob (voiced by Gedde Watanabe) is the tyrant owner of Nob's Arkaid, where Robot Jones and his friends hang out. He keeps telling kids that they're breaking his arcade machines, every time they play with them. This is often caused by Robot Jones exploding causing damage to the nearby machines, or by the arcade games themselves explode. In "Hookie 101", it is revealed that his arcade gives a discount on game tokens during school hours.
