Xiaolin Showdown (Seasons 1–3)

Xiaolin Showdown (2003–2006) is an American animated series created by Christy Hui for Kids WB — stream every episode online on iFILM. Three seasons, 52 episodes, and a world where kung fu and ancient magic settle every argument.

Four young warriors-in-training — Omi, Kimiko, Raimundo and Clay — race against villains to collect powerful relics called Shen Gong Wu before they fall into the wrong hands. Most episodes build to the same ritual: a relic surfaces, both sides scramble for it, and the whole thing comes down to a one-on-one magical duel — a Xiaolin Showdown — where the loser forfeits everything they came with. The voice cast includes Tara Strong, Tom Kenny, Grey DeLisle and Jeff Bennett.

What kept the show running wasn't the action — it was the characters. The villains are genuinely funny and weirdly likeable, the heroes spend half their time bickering with each other, and nobody is particularly dignified. A sequel series, Xiaolin Chronicles, followed in 2013. Watch all seasons of Xiaolin Showdown online on iFILM.
