Roberto

Roberto is a criminal robot, serial bank robber, and an old friend of Bender. 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. 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 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.
