Reversing Mirror

From Xiaolin Showdown Wiki

The Reversing Mirror is a Shen Gong Wu that is used to reverse the effect of any other Shen Gong Wu; for example, the Changing Chopsticks would make a person gargantuan instead of tiny, and the Two-Ton Tunic would make the user nearly weightless. It can be used to reflect attacks from offensive Shen Gong Wu, as well as Dojo Kanojo Cho's fire.
