Marinette's great uncle, the world-renowned Chinese chef Wang Cheng, visits Paris to participate in a cooking show called The Greatest Chef in the World. Before the competition begins, Marinette and Adrien run into Chloé, who is on the judges' panel. Chloé mocks Cheng for being a foreigner, and in retaliation, Marinette fires back with her own insults. Chloé sabotages Cheng's famous Celestial Soup, causing him to get poor results in front of the judges. Confused and upset, Cheng becomes influenced by Hawk Moth and turns into Kung Food, a villain who enslaves those who had eaten his ruined soup and who plans to cook Chloé in the soup.
