Xiaolin Showdown is an American animated television series that aired on Kids' WB and was created by Christy Hui. Set in a world where martial arts battles and Eastern magic are commonplace, the series follows four young Xiaolin warriors in training who battle the Heylin forces of evil. They do this by protecting Shen Gong Wu (ancient artifacts that have great magical powers) from villains that would use them to conquer the world. Typical episodes revolve around a specific Shen Gong Wu being revealed which results in both sides racing to find it. Episodes usually reach a head when one good and one evil character must challenge each other to a magical duel called a Xiaolin Showdown for possession of the artifact.
Originally airing on the Kids' WB block of programming on WB Network from 2003 to 2006, the series ran for 3 seasons and 52 episodes. Reruns also aired on Cartoon Network from 2006 to 2007. Xiaolin Chronicles, a direct sequel of the series was previewed on August 26, 2013 on Disney XD. It began its long-term run on September 14 the same year.
