Deborahbot 5000

Deborahbot 5000 is a damaged robot who uses deadpan humor while trying to pass as a human.

Throughout The Mitchells vs. The Machines
Before Deborahbot 5000 malfunctioned He was like the other Pal MAX bots, Him and other Pal MAX bots attack the Mitchells at a Dinosaur themed Gas station but eventually him and Eric get crushed by a Dinosaur statue and Malfunctioned.

Personality
Preceding his malfunction, he acted like the rest of the robots, ruthless. After a giant object fell on him and Eric, he appears to have malfunctioned, causing him first to glitch out and act kinder / more helpful, and eventually act as a part of the family.

Physical appearance
Deborahbot appears to be a robot with a rather messy red marker face and a black white colored body with black in some parts

Trivia

 * Deborahbot 5000 is one of the two Pal Max bots to not have been destroyed after Pal had short circuited.
 * He appears to not short circuit after seeing Monchi, presumably because he had already figured out what creature Monchi is.
 * At the end of the movie, you can see them in the Mitchell's Household during a call between Katie and her parents.
