Roberto (Futurama)

Roberto (b. 3001) is a recurring character in Futurama. He is a mentally unstable robot who enjoys stabbing people and objects, as well as robbing banks. He is regarded as being mentally unstable and has been seen in the Hal Institute for Criminally Insane Robots multiple times, threatening both patients and doctors with knives, as well as escaping at least once. His insanity had been cured momentarily in "Bender's Game", but suffered a concussion and returned to his previous madness seconds later.
