Roboto is a robot Heroic Warrior.[40] He was introduced into the Masters of the Universe toy line in 1985. His first appearance is in the Mattel mini-comic "The Battle of Roboto", in which he is built by Man-At-Arms, who gives him a cybernetically-enhanced heart, which enables him to feel human emotions and interact with his comrades as a human rather than as a machine.[41] He was an exceptionally brave fighter, even to the point of taking on Hordak in single combat in one issue.
