In a case of mistaken identity, the entire city turns against Captain Extraordinary when an evil super-villain virtually identical to X begins to strip superheroes of their powers. Can Captain X stop the mysterious Dark Matter, save the city and restore his name? Things have gotten complicated at home too with the Aliens morphing into some kind of hibernation pod and Ben's mother, Laura, being hospitalized with a strange illness. Not to mention it's Ben's first day at City Central Polytech, where he meets beautiful student Wendy Choo.
