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.
