Danny Phantom is an American animated superhero action adventure television series created by Butch Hartman for Nickelodeon. The series follows Danny Fenton, a teenage boy who, after an accident with an unpredictable portal between the human world and the "Ghost Zone", becomes a human-ghost hybrid and takes on the task of saving his town (and the world) from subsequent ghost attacks using an evolving variety of supernatural powers. Danny is aided in his quest by his two best friends Sam Manson and Tucker Foley, and later, his older sister Jazz, who for most of the series' run are among the only people who know of his double life.
