S5·E1 Relics of Demon Past

Drago breaks out of Section 13 on a mission to absorb the demon chi that is held in the original artifacts used to defeat the demons so many years ago. He finds the Enforcers at a petting zoo and transforms them into dragon-human hybrids. Drago locates the fan that holds the chi of the Wind Demon. Meanwhile, Jade gets into the nasty habit of burping. Jackie and Captain Black hunt Drago down to a Chinese-themed car wash, where the fan is located. Unbeknownst to everyone, Jade absorbs the demon chi. At school, her burps create powerful wind storms, and she begins to transform into a frog. Drago attacks Jade at school in order to absorb the chi, but Uncle and Tohru arrive to capture it instead. Drago fires the Enforcers and turns them back into their old human selves after they prove that they are weak and useless.
