Xiaolin Showdown - Season 2 Episode 18

Upon seeing the rare Heylin comet circling the Earth, Master Fung orders the Warriors to not use any Shen-Gong-Wu for three days. The comet makes the Wu have a mind of their own if used by anyone. Wuya sees this as an opportunity to tempt the Warriors to use the Wu. After using the Golden Tiger Claws and Sword of the Storm to save his hometown from a volcano eruption caused by Jack and Wuya, Raimundo literally becomes attached to the Claws. The Shen-Gong-Wu begin to have a mind of their own and attach to Raimundo, making him 'monster-like'. Once Raimundo loses all his self control, Wuya plans to take over his body and finally carry out her plans to rule the world.
