Thousands of years ago, a furious battle was waged between the great and noble Xiaolin Dragon Dashi and the evil Heylin witch Wuya. This was the first Xiaolin Showdown. Wuya pitted her dark magic against Dashi and his mystical power objects, the Shen Gong Wu. In the end, Dashi triumphed, and Wuya was forever imprisoned in a simple wooden puzzle box. The threat averted, Dashi spread his Shen Gong Wu around the earth. For generations, they have secretly maintained the balance of good and evil. And a long line of Xiaolin Dragons has stood ready to face evil, should that balance ever shift.
