Who Is He? Captain America has The Red Skull. Batman has The Joker. Superman has Lex Luthor. So who is Iron Man's archenemy? That would be The Mandarin. In the comics the character is a true genius and a sociopathic megalomaniac who wishes to rule the world. He was also originally designed with a sci-fi/fantasy element, wearing ten magic rings that grant him powers.
How Does He Fit? The Mandarin, as portrayed by Sir Ben Kingsley, is the inscrutable leader of The Ten Rings, an extremely powerful terrorist organization known for causing mayhem around the world (but more on them in a minute). He’s drawn into Iron Man’s world when he is goaded by the hero, and chooses to make a special project out of ruining Tony Stark’s life.
The Ten Rings
What Is It? The long and short: The Ten Rings is a terrorist organization run by The Mandarin. The name of the organization comes from the rings that the leader wears on his hands.
How Does It Fit? The Ten Rings has actually been a part of the Marvel Cinematic Universe since the beginning. The crew that kidnaps Tony in Iron Man is part of the organization (as indicated by the flag hanging on the wall during the ransom video), and in Iron Man 2 the character that delivers a fake passport to Anton Vanko (Mickey Rourke) is credited as “10 Rings Gangster.” Obviously, with The Mandarin as the main villain of Iron Man 3, The Ten Rings has a role in the plot.
