Robotboy is the main protagonist of the show of the same name. He is the latest creation of the world renowned scientist Professor Moshimo. Due to fears that Robotboy would be stolen by his arch-enemy Dr. Kamikazi and his main henchman Constantine to be used to take over the world, Professor Moshimo entrusts Robotboy to 10-year-old Tommy Turnbull, his biggest fan. While being protected by Tommy and his two friends Lola Mbola and Gus Turner, or "G-man" as he calls himself, Robotboy learns how to behave and act as if he were a real boy.
Robotboy resemble to a real boy, He has a round head with blue ears, More of his body is white, but his hands and feet are blue. He also has light blue eyes, His eyes also turn red when he going to use super activation.
In deactivate mode, He is small and resemble to a doll, His ears are close and his eye are blue.
In super activation mode, He is taller and has medium silver body instead of white, His ears, hand, and feet are dark blue and his ears are also taller. He has a dark blue mask-like face with red outlining.
Robotboy is very naive almost to a fault, and is very easily led (most often by Gus, and into certain negative situations). 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 overprotective of Tommy and his friends (and Robotgirl during their brief encounter) On more than one occasion, 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 over-protectiveness 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 (except for Gus). He appears to like having fun with Tommy and on occasion Lola.
