Re: Iron Man 3 confirmed
Fing Fang Foom was never mystical, as I recall. There's nothing magic about him. He's an alien who happens to resemble a chinese dragon(maybe the source of legends about dragons in china, for all I know). And the components of his downed ship's hyperdrive is what the Mandarin uses to make his rings.
