The Unidentified Alien was one of three alien beings who decided to visit Earth in the year 2340 after receiving the message of peace sent by Professor Von Ziflin using his Radio Spectrum Voltage Pacifier. Before the Unidentified Alien and his traveling companions Zorgon and Nexor arrived, their Alien Spaceship encountered Prime Evil, who managed to take control of the space vehicle and marooned all three of them on a dangerous, uninhabited Asteroid.
