Robot Santa (voiced by John Goodman in the first appearance, John DiMaggio in later appearances) is a robot created in 2801 by The Friendly Robot Company to judge beings as naughty or nice and distribute presents or punishments accordingly. Due to a programming error, his standards are too high and he judges everyone to be naughty (with the one-time exception of Dr. Zoidberg, who got a Pogo-Stick as a present). In the event that he judges himself naughty, Robot Santa can regenerate his head when it explodes. This leads him to go on destructive rampages across Earth every Christmas using Christmas-themed weapons, such as grenades shaped like Christmas ornaments, bicycle guns, and T.O.W. missile launchers to punish "naughty" beings. He resides in a death fortress on Neptune along with a number of Neptunians that act as slave labor for the toy factory.
