Xiaolin Showdown - Season 2 - Eps 22: The Apprentice
Chase Young is looking for an apprentice. Either Katnappé or Jack will be able to win it. Katnappé has reprogrammed the Warriors' U-bots to be evil. Master Fung informs the Warriors that their new threat is Chase Young, and he must teach the four monks to be deceptive in order to triumph. However, Omi is too trustworthy. After Chase chooses Katnappé to be his apprentice, Jack turns to the Warriors and asks to join the side of good. Omi trains Jack the best he can to release all the evil that is inside of him, but after Katnappé attacks the Temple, Jack takes off with the Warriors' Wu, which tests Omi's trust.
