Re: So Cap's Shield is tattooed on Mandarin's neck. Anyone care to explain?
I think the "Captain Anarchy" theory is the closest to being accurate, sort of a satirical jab at the hero/symbol.
Otherwise it could be like they said-- he has a collection of warrior iconography, from the samurai hair to the Osama beard, to... a Captain America tattoo. It'd be kind of an interesting twist if he actually admired Cap. But I like the Anarchy idea people are offering up.
