The Iron Man 3 trailer was released recently. In it, there's a villain who seems to be targeting Tony Stark. It seems like he's trying to prove a point about superheroes - that there is "no such thing".
It seems to me like we're meant to understand that the villainous narrator is this guy:
He's got a distinctive tattoo on the back of his neck that almost looks like Captain America's shield:
He's also got some distinctive jewelry (though that isn't visible in the shot where he's taking off his hood, above):
Who is this guy? Are there any hints in the trailer about what existing Marvel villain we might be battling here? Are we going to roughly follow any existing Marvel plots, or are this story and its villain new territory?
What intel do we have on the Iron Man 3 villain?
