CallumBot

Callum (also known as "Callum bot 2.0") is one of the core members on the Nerdinatiors. It is widely speculated and generally accepted that he is a robot, however, his is unconfirmed at the moment

Roboticism
Due to his adept skills at mathematics and memorisation, and his undue obsession with spare wires, it is assumed that Callum is a robot or into robotics. Indeed, when faced with the robotic army in the alternate dimension plagued by a Cyborg War, Callum was able to seamlessly blend in and become a medic for six months whilst waiting to be rescued by the rest of the gang.
