Ever since appearing in Metropolis, Superman has gotten quite a bit of fame, and with that fame, he's also acquired enemies. One such enemy is Lex Luthor of LexCorp. After John Corben, a soldier, and ex of Lois Lane, who joined the military for validation and attention and saw that attention be stolen by Superman, is approached by Lex Luthor with a proposition to turn him into a soldier strong enough to stop Superman, he accepts without hesitation. Luthor funds, and controls, an operation that turns John Corben's body into a metal skeleton. Now Metallo, Corben is instructed to kill Superman, for the good of Metropolis. Meanwhile, Rudy Jones, a family man and worker at a chemical plant owned by LexCorp, is involved in a work accident that causes his body to meld with radioactive materials, transforming him into a purple, parasitic entity that needs constant absorption of life energy to survive. Superman’s presence on Earth has even garnered attention from off-world threats as the intergalactic bounty hunter Lobo enters, searching for Kryptonian prey. Alone, Superman might fall under the insurmountable odds, but Superman is not alone. He’s never been alone.
