Xiaolin Showdown - Season 2 Episode 1
Days Past

After learning none of the Shen-Gong-Wu can stop Wuya, the Xiaolin Apprentices team up with Jack. They figure out the only way they can put an end to Wuyas reign is to travel back in time 1500 years, where Grandmaster Dashi first defeated her. Omi goes through Jacks time machine alone with only one Shen-Gong-Wu, leaving the rest with the other three to protect themselves. Omis plan is to find Dashi and receive another puzzlebox to trap Wuya in.
