The Cobalt Robot was created by Ralph Roberts who was a prisoner
Romulus Augustulus (Earth-616), Ralph Roberts (Earth-616), and Cobalt-Robot (Earth-616) from X-Men Vol 1 34 0001
of Tyrannus at the time. The robot's mission was to destroy the Mole Man's robot made of diamond. The robot was successful in destroying Mole Man's robot, but the robot was then destroyed by the X-Men by knocking it into a lava pit when they arrived to rescue Roberts. Tyrannus couldn't understand how the Cobalt-Robot could lose, unaware that Roberts had sabotaged the robot.[1]
