We’re talking of course about The Mandarin. Created by Stan Lee and Don Heck back in 1964 in “Tales of Suspense,” in the comics he’s a descendant of Genghis Khan and a member of one of pre-communist China’s richest families. Raised from birth to be an amazing warrior and scientist, he creates 10 rings made from re-purposed alien technology that give him superpowers. Naturally, he wants to take over the world, and Iron Man is one of his biggest obstacles to achieving that goal.
In the movies, things are of course completely different. Ten Rings is the name of a terrorist organization, not magical jewelry.
