The main villain in Shang-Chi is the main character’s own father, Wenwu, who is also known as the Mandarin. Unlike in the comics, neither Zheng Zu nor Fu Manchu will be the name of the titular hero’s dad.
Wenwu leads the terrorist organization the Ten Rings. Those who watched Iron Man 3 may recognize the Mandarin’s name as a villain from that movie, but unfortunately, this wasn’t a reference to the upcoming film.
In fact, the Mandarin in Iron Man 3 wasn’t really the Mandarin at all. He was really Trevor Slattery, an actor hired to pretend to be the Mandarin by Aldrich Killian. But we learned from the short film All Hail the King that a real Mandarin was still out there and that the Ten Rings have quite a bit of power.
A deleted scene from the first Ant-Man movie would also reintroduce the Ten Rings. According to Polygon, in the scene, a Ten Rings member is present when bad guy Darren Cross is trying to sell his Yellowjacket armor. It’s a small but meaningful representation that the organization has been around all along.
Shang-Chi and the Legend of the Ten Rings hits theaters Sept. 3, 2021.
