Jailbot is a robot made to guard Superjail, where he serves as both a guard and a servant to The Warden. He is portrayed as being almost invincible in combat, and filled with more weapons taht should logically eb able to fit into his body.
Jailbot is seen at the beginning of every episode capturing Jackknife (a characetr who can be seen escaping in ever episode). He will usually apprehend him an an unneceserilly violent fashion, and usually causes more harm than good. Jailbot does, however, show an affinity for children, often giving them sweets when he apprehends Jackknife. It is possible that his affinity for children stems from his own self-identity as a young child, as shown from Jailbot's dream in "Dream Machine", where Jailbot dreams of himself as The Warden's son.
