Relics of Demons Past (S05E01)

Drago escapes from Section 13 with the goal of harnessing the demon chi stored in the original artifacts that once defeated the demons. He encounters the Enforcers at a petting zoo and morphs them into dragon-human hybrids. Drago soon discovers the fan containing the chi of the Wind Demon. Meanwhile, Jade picks up an unpleasant habit of burping. Jackie and Captain Black track Drago to a Chinese-themed car wash, where the fan is hidden. Unbeknownst to them, Jade has absorbed the demon chi, causing her burps to unleash powerful wind storms and triggering a transformation into a frog. When Drago confronts Jade at school to claim the chi, Uncle and Tohru arrive just in time to intervene. After realizing the Enforcers are too weak, Drago dismisses them and reverts them back to their human forms.
