XS stands for Xiaolin Showdown. Originally airing on the Kids WB! block of programming on WB Network in 2003, the series ran for 3 seasons and 52 episodes. 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.
