This paper toy is Robotboy, a robot built by Professor Moshimo, and designed to resemble a real boy, the character is from the same named British animated television series. The papercraft was created by LordBruco.
Robotboy has three activation modes: deactivation, where he resembles a doll; normal, where he is roughly Tommy Turnbull's height; and super activated, where he is twice Tommy's height, and has a plethora of machine guns and rockets. During the opening, it's stated that Robotboy was given to Tommy for Robotboy to learn how to be more like a human boy, but it is not stated how long he had been activated or why Tommy was his chosen guardian. Robotboy is roughly eighteen inches tall in normal mode, twelve in toy mode, and six foot in super activation.
Roboyboy is naive, and is very easily led. However, when things come down to the wire, he's often the first to react and has a fair understanding of his surroundings and circumstances.
Robotboy is over-protective of Tommy and his friends. On more than one occation, he's been openly willing to do anything to keep each of them safe. If Tommy orders him to stop though, Robotboy will stop almost instantly. Robotboy's overprotectiveness is more blatant in the beginning episodes of the first season, then again near the end of the season. This cycles throughout the first three seasons that were aired.
He is shown not to like dishonesty, and has a fair bit of respect for those around him. He appears to like having fun with Tommy and, on occasion, Lola. [Source: wikia]
