The villain of Iron Man 4 is Lord Manchu, no, the real one

There's no Lord Mangan in the Iron Man movies, that's a fake. You can check out "Long Live the King", which states that the real Lord Mangan and his gang, the Ten Commandments, will settle the score with the fake Lord Mangan. In the comics, Lord Manchu is the Chinese version of Tony Stark (who is very rich) (and has a lot of scientific achievements). He wears a ring on each of his ten fingers and has different abilities. In the back, he lost ten rings and built a unicorn arm (dragon arm). Lord Manchu himself has great Chinese Kung Fu. As for whether there are superpowers, it depends on how you interpret "superpowers".
