A Carbot who speaks like a stylish gentleman. A self-proclaimed 'world's best spy,' he always mutters about grand conspiracies whenever something happens. He sometimes fails because he tries too hard to look cool, but he possesses excellent skills like 007.

The mentor of the Carbots. He is an old friend of Guest's grandfather and the one who introduced the Carbots to Guest. Though he sometimes groans due to his old age, he is a true teacher who wisely leads Guest and the Carbots.
