Trevor Slattery is a character portrayed by Ben Kingsley in the Marvel Cinematic Universe (MCU). An actor hired to portray the legendary terrorist leader of the Ten Rings dubbed "the Mandarin", he first appeared in the film Iron Man 3 (2013) and reprised the role in the Marvel One-Shot All Hail the King (2014) and in the film Shang-Chi and the Legend of the Ten Rings (2021), which features the real leader of the Ten Rings, Wenwu. He will also appear in the upcoming Wonder Man series. General response to the character was mixed, with many comic fans criticizing the character and how his reveal affected the film's Mandarin portrayal, while others defended the twist by noting its social commentary and how it avoided the racist caricature of the comics' Mandarin.
