As the Man of Steel prepares to reveal himself to the world and declare his longstanding love for "Daily Planet" reporter Lois Lane, an old nemesis teams with a foe of unlimited power to wreak havoc over Metropolis in this animated adventure that pits Superman against a villain the likes of which the world has never seen. A powerful computer with a special strain of kryptonite infused to his body and a hunger for world domination, Brainiac forges an unholy alliance with the dreaded Lex Luthor that aims to bring the world's most famous superhero to his knees. When a force beam originally intended to take out Superman instead blasts Lane, the race is on for the desperate hero to enter the dreaded Phantom Zone and find the cure that will restore her health. The nefarious partnership between Luthor and Brainiac takes a turn for the worse, however, when, believing The Man of Steel to have buckled under the pressure of his powerful blast, Brainiac betrays his one-time partner to strike terror into the very heart of Metropolis.
