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 Omi, Raimundo, Kimiko, and Clay, four young Xiaolin warriors in training who, alongside their dragon companion Dojo, battle the Heylin forces of evil, especially series antagonists Jack Spicer, Wuya, and Chase Young. The Xiaolin warriors set to accomplish this by protecting Shen Gong Wu, a set of ancient artifacts that have great magical powers, from villains who could use them to conquer the world. Typical episodes revolve around a specific Shen Gong Wu and the resulting race on both sides to find it. Episodes often climax with one good and one evil character challenging one another to a magical duel called a Xiaolin Showdown for possession of the artifact.

The series won a Daytime Emmy Award in 2005 and was nominated for three additional Daytime Emmy Awards, one Annie Award, and one Golden Reel Award.
