Trevor Slattery is a fictional character created for the Marvel Cinematic Universe movie Iron Man 3, the 2014 Marvel One-Shot All Hail the King, the 2021 movie Shang-Chi and the Legend of the Ten Rings, and the 2026 television series Wonder Man. In the movie, he is hired to pose as the Mandarin for real villain Aldrich Killian, before he is kidnapped to work as entertainment for the Ten Rings. On returning to America, he begins working for Damage Control to investigate Simon Williams, whom he instead befriends. Trevor then becomes the Mandarin for real publicly to take credit for an explosion accidentally caused by Simon. He was played by Ben Kingsley.
Trevor Slattery is a washed-up British actor handpicked by Aldrich Killian to fake the identity of the Mandarin of the Ten Rings.
Trevor Slattery is a fan-favorite but Marvel purists aren't happy that he isn't actually the Mandarin.
