jailbot
is a tombstone-shaped levitating robot that performs tasks in and around Superjail, such as piloting vehicles and transporting prisoners. He essentially acts as the Warden's gofer. Jailbot is mute, with a dot-matrix screen that displays a simple expressive face. He is gratuitously vicious in most things, often killing numerous people in attempting to accomplish his task. Christy Karacas described him as a "red headed stepchild... seeking approval."
Jailbot, you are the only one I can trust these days.
