The Super-Humanoid was a robot created by the Leader. The robot was activated to assist him in his plot to take over the USA’s nuclear missiles and start a nuclear holocaust. The Super-Humanoid was destroyed by the Hulk, who threw it into an active volcano.
A later Super-Humanoid was built by the Leader to release the Rhino from prison so the Leader could use the Rhino in a plot. As a test of his strength, and with the Leader's blessing the Rhino destroyed the Super-Humanoid with a single blow.
