History

  Suffering from mental illness after being brainwashed, Doc Magnus was manipulated into continuing his robot program for the U.S. Army even though he was not fit for the task. The result was the destructive Plutonium Man. Programmed with Magnus' disturbed thought patterns, the robot went berserk. Like Magnus at the time, it hated the Metal Men, and beat them all before reaching critical mass and self-destructing. However, nothing in nature is destroyed, just transformed from one state into another. As one entity, the Plutonium Man could no longer survive so he split into two creatures, each below critical mass. The Master, the Plutonuim Man's consciousness, appeared as a twisted duplicate of Doc Magnus, while the unthinking Drone could transform into any element the Master desired. While the Master sought revenge on Magnus, the Drone fought the Metal Men. However, the Metal Men defeated both threats by plunging them both together into a fissure. This apparently meant the ultimate end of the Plutonium Man.
