Robotboy 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 and Gus (or “G-Man” as he calls himself), Robotboy learns how to behave and act as if he were a real boy while occasionally battling Dr. Kamikazi and Constantine who sought out to capture him.
