The surname Bender derives from both British and German origin.
In England, it derives from old Benden or Benbow. In Germany, it is a form of Fassbinder (Cooper). It is an occupational name in both English and German forms.
According to the character's back story, Bender was built in 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.
