The Robot Devil appears in the film series on several occasions, most notably The Beast with a Billion Backs, where Bender makes a deal with the Robot Devil exchanging his first-born son for the Armies of Hell. Bender more than happily locates his son and kicks the child into a vat of lava, causing the Robot Devil to comment, "That was pretty brutal, even by my standards." Bender simply replies, "No backsies!" In Bender's Big Score, he conducts the band at Lars and Leela's wedding.
