Danny Phantom is an American superhero animated series created by Butch Hartman for Nickelodeon. It was produced by Billionfold Studios and distributed in Canada by Nelvana, a Canadian animation company. The series follows 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. He is aided in his quest by his two best friends, and later, his older sister, who for most of the series' run are among the only people who know of his double life.
The series premiered on April 3, 2004, its first episode airing after the 2004 Kids' Choice Awards, and ended on August 24, 2007, totalling 53 episodes over three seasons. Danny Phantom has received critical and audience acclaim, with praise primarily directed at its ensemble cast and comic book-influenced themes and storyline. Hartman himself has noted that the series is arguably his most popular and acclaimed work, despite its relatively short production life compared to The Fairly OddParents. Danny Phantom has spawned video games, home video releases, as well as toys and various other merchandise.
