"A Breed Apart," the first-season finale of Mutant X, introduces Patient Zero, who figures to be a big player in the show.
"He's the most powerful new mutant," Howard Chaykin, executive story consultant of Mutant X, told The Continuum. "He's an interesting new character and a lot of fun. He's a seductive, dark character who is a one-man match for all of Mutant X."
