Xiaolin Showdown
Wu Got the Power
S3 E10:
The young monks must use their Wudai powers in order to master and absorb their Elemental SGW. Omi is so anxious to prove himself that he decides to learn not only his own Elemental SGW, but the others also. As a result, he "short-circuits," overloading himself with powers that he has no way of controlling. His energy force is so extreme that he becomes a menace to anyone near him and is forced to leave the Temple until the others can figure out how to bring him back to his old self.
