Tom Servo is a fictional character from the American science fiction comedy television show Mystery Science Theater 3000 (MST3K). Tom is one of two wise-cracking, robotic main characters of the show, built by Joel Robinson to act as a companion and help stave off madness as he was forced to watch low-quality films (ironically, he, along with the other bots, is made from the parts that would have otherwise allowed Joel to actually control the film). At least during the Comedy Central era, he was somewhat more mature and cynical than his companion Crow T. Robot. Tom, more often than the others, signals the need to exit the theater to perform host segments.
