Taekek: Robotboy British Animated Television Series

Robotboy is a British/French co-produced animated television series which is produced by French production company Alphanim with TV Channels France 3 and Cartoon Network as well as Luxanimation. It was created and designed by Jan Van Rijsselberge and was directed in Alphanim's studio in Paris by Charlie Bean, who worked on other programs such as The Adventures of Jimmy Neutron: Boy Genius for Nickelodeon and Camp Lazlo for Cartoon Network. It was first aired in the United Kingdom on 1 November 2005 on Cartoon Network. The pilot episode premiered in the United States on 28 December 2005 as part of a "sneak peek" preview week for the network's new Saturday morning cartoon lineup that debuted on 14 January 2006.
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.

Most of the time, Robotboy has blue drums protruding diagonally on either side of the head. While Superactivated, they become horns. Deactivated and Activated forms look very much the same, except the deactivated form's head drums are withdrawn into the head, and his limbs are also withdrawn into his body. While activated, Robotboy has mechanical tentacles concealed in his palms and thrusters on the soles of lower part of his leg, enabling him to fly. While Superactivated, Robotboy's fists and feet and head are much larger and now have all kinds of lasers, homing missiles and machine guns. Briefly seen is an ink spray that can identify invisible targets and, of course, dramatically increased physical strength. Robotboy's most common Superactivated weapon is the machine gun arm. Many random weapons appear, and many are rarely seen twice, even in the same episode.
It also seems Robotboy is amphibious. In later episodes robotboy receives an unbreakable metal for his body to be made. This becomes seen as robotboy never takes damage.
The Activation controls for Robotboy are built into a special, orange watch that Tommy wears. The watch is in the shape of Activated Robotboy's head. In the episode "Robot Rebels", Robotboy smashes the watch after being tricked by Kamikazi. It is unknown how Tommy gets another watch, but it is safe to presume that Professor Moshimo had a spare one.
Robotboy, since he is a boy, had many cute designs on him throughout the show. (small voice, sparkle in his teeth, twinkle in his eye, etc.)(wikipedia)
