Roberto

Roberto is a criminally insane manbot, serial bank robber, and an old friend of Bender's. He was built in 3001 by a team of engineers with a desire to build a completely insane robot. According to Roberto, however, "they failed!" However, he is still one of the most unstable and dangerous robots in New New York. He robbed a bank but got away while Bender and Fry were arrested for his crime. After robbing the same bank a second time, he was put in the same robot asylum as Fry and Bender (and unfortunately Fry's new cellmate). After escaping with Bender, he robbed the bank a third time, and took cover in the Planet Express building, holding the employees hostage. After a scuffle with Fry (and the revelation that his mental and emotional problems may have been the result of years of abuse), he jumped out the window and was eventually caught. He later appeared to be upgraded to accept next generation Robots. He was also at Nixon's Big Robot Party where all robots were to be destroyed. Eventually he was sent to jail on Will Riker's Island and seems to have replaced his knife with a sock.

In 3012, Roberto attempted to mug Hermes and LaBarbara, demanding that they hand over their skin. However the mugging was foiled by officers URL and Smitty, and he was taken to the electromagnetic chair to be executed. This execution was broadcast on television.

He was buried in the robot cemetery, but it wasn't long before his grave was robbed by Hermes, Bender, and the Professor who were in search of a robot brain. Roberto's brain was then taken back to Planet Express and was placed in a robotic version of Hermes' body, where then proceeded to attack the crew with a key. Roberto peeled off a piece of Hermes' skin and ate it. However due to the skin absorbing years of LaBarbara's hot cooking, it melted Roberto's body and he changed into a metallic puddle on the floor of the observation deck.

In 3013, Roberto had somehow been reincarnated and attempted to rob Zoidberg's new girlfriend Marianne's flower stand. However, he refused to carry the money in a bag, because he cared about the environment.

In Bender's alternative reality, Cornwood, Roberto was the king.

Trivia

 * Roberto seems to have an interest in stabbing things, and even has his own "Stabbing Knife" almost everywhere he goes. It seems to be a deranged favorite hobby of his.
 * He mentions his "mother" during the only real time he has shown any fear. Who he is referring to may or may not be Mom, the creator of most Robots in the universe. Roberto brings up that she welded him to a wall at one point which seems to be one of the reasons for his insanity. However, in Bender's Game, he implies that he was built as an insane Robot.
 * Roberto is the third Build-a-Bot in the Toynami Futurama figure line. He is also the first to only go through two series instead of three (with two figures a series).
 * The shape of his eyes resembles some sort of mask and his body resembles a tombstone which fits with his personality, being a person who loves to rob and stab things.
