Bender Bending Rodríguez (designated in-universe as Bending Unit 22, unit number 1,729, serial number 2716057) is a main character in the animated television series Futurama. He was created by series creators Matt Groening and David X. Cohen, and is voiced by John DiMaggio. He fulfills a comic, antihero-type role in Futurama and is described by fellow character Leela as an "alcoholic, whore-mongering, chain-smoking gambler".
According to the character's backstory, Bender was built in Tijuana, Mexico (the other characters refer to his "swarthy Latin charm"). Viewers are informed, through his own testimony, of Bender's prejudice against non-robots: His dialogue often contains anti-human expressions such as "kill all humans". Exceptions who are not subject to Bender's prejudicial attitude are those individuals on his "Do Not Kill" list, which seems to comprise only his best friend Fry and his colleague Hermes (Hermes is added after the episode "Lethal Inspection"). However, Bender is also occasionally portrayed as possessing a sympathetic side, suggesting that he is not as belligerent as he claims, a view often echoed by his friends.
The name "Bender" was chosen by series creator Matt Groening in homage to the character John Bender from The Breakfast Club.
Bender's visual design went through multiple changes before reaching its final state. One of the decisions which Matt Groening found to be particularly difficult was whether Bender's head should be square or round. Initially he worked under the idea that all robots would have square heads in the year 3000; however, it was later decided that Bender's head should be round, a visual play on the idea that Bender is a "round peg in a square hole".
