Decapitron is one of the puppets featured in both Puppet Master 4 and Puppet Master 5: The Final Chapter.
Its appearance is modeled after André Toulon's outfit from Puppet Master III: Toulon's Revenge. It wears a brown jacket with a black undershirt, a black belt, and black gloves. Its regular head has indented eyes and nose, and the base of its head seems to resemble the base of a light bulb. Its name seems to reflect the fact he has interchangeable heads, when taking them off would make him decapitate himself.
Not much is known about Decapitron's background, other than the fact he was an unfinished puppet André Toulon worked on while he was alive. Decapitron's height and weight are also not revealed in the films as well. Decapitron has the soul of André Toulon, the namesake and creator of the puppets in the "Puppet Master" franchise. Unlike the other puppet creations of André Toulon's, Decapitron cannot be activated by having the formula injected directly through a needle. Rather, it has to be activated by the formula combined with an electric current.
