Xiaolin Showdown S02 E03 The Shard of Lightning

"Gong Yi Tanpai!"

After Katnappé releases Wuya from the puzzle box, the two form an unhealthy alliance. Jack builds another robot, but this time, it's a clone of himself, who is much quicker, smarter, and gets all the good jokes. Jack and his clone use the newest Shen-Gong-Wu, Shard of Lightning, to freeze time and quickly steal most of the Warriors' Shen-Gong-Wu. The Warriors must think of a plan to stop them, while Wuya starts to regret teaming up with Katnappé.
