named Zheng Zu, Master of the Ten Rings, a martial arts school that uses mystical powers and techniques based on the powers of his 10 rings from the mainstream continuity. Like his namesake, he is the father of Shang-Chi, who is wanted for the murder of Lord Tuan, the master of the Iron Fist school, the main rival of the Ten Rings school. It is later revealed Zu sent his assassin, Red Sai of the Red Hand school, to assassinate Tuan, but she ultimately failed. To spare his lover and her students from the Emperor's wrath, Shang-Chi killed Tuan; Zu had his son implicated and exiled for the murder to cover his own involvement. Representing the Ten Rings, Emperor Zu hosts a tournament held every 13 years to decide who the next ruler of K'un-Lun should be, a position he has held for 100 years. When Shang-Chi returns from his exile to represent his own school, the Lowest Caste, Zu allows him to participate, but alters the rules so that Shang-Chi would have to defeat every representative before facing him in the Thirteen Chambers. During their fight, Zu attempts to kill his son with the Spectral Touch technique, only for the move to pass through him due to Shang-Chi having learned how to become intangible. Shang-Chi proceeds to use nine of the 10 techniques against his father and ultimately defeats him with the Gorgon's Eye, which turns him into stone. With Zu's defeat, Shang-Chi becomes the new emperor of K'un-Lun. In other media Television The Mandarin appeared in The Marvel Super Heroes, voiced by Henry Ramer.
