Xiaolin Showdown (2003)

S2E4 The Crystal Glasses

Following their successful acquisition of a new Shen-Gong-Wu, a Russian merchant named Vlad becomes part of the Xiaolin Dragons-in-training. When Omi utilizes the newly obtained Shen-Gong-Wu, the Crystal Spectacles, he glimpses a future where he turns to darkness. Disturbed by this vision, Omi rapidly departs from the Xiaolin Temple, convinced that he can no longer pursue his path as a Xiaolin Dragon-in-training.
