In the 1970s, Marvel Comics used Fu Manchu as the principal foe of his son, Shang-Chi, Master of Kung Fu. As the result of Marvel Comics later losing the rights to the Fu Manchu name, his later appearances give him the real name of Zheng Zu. The upcoming Marvel Cinematic Universe film adaptation, "Shang-Chi and the Legend of the Ten Rings" (2021), will replace Fu Manchu with the "real" Mandarin (Tony Leung); thus downplaying yellow peril implications since the Mandarin is opposed by an Asian superhero, Shang-Chi (Simu Liu), while omitting references to the Fu Manchu character.
