Lex Luthor uses a projector ray (reverse camera) to disguise himself and his assistant Orville Gump as SuperFriends in an elaborate plot to destroy them. Luthor aligns himself with evil fire demons who originate from the sun. They aid Luthor in capturing the Superfriends and placing them in death traps. The demons then change the color of the sun from yellow to red which cause Superman's powers to vanish. However, the sun demons double-cross Luthor and he has no choice but to free the Superfriends in an effort to save himself and Earth (so he can continue to take it over, of course!). Superman uses the Super-Mobile to chase the fire demons back into the sun...which causes the sun to return to its natural color...which restores Superman's powers. Luthor and his assistant are sent back to prison. NOTE: Orville Gump is based on Otis, the character played by Ned Beatty in the 1978 Superman movie.
