You know what makes this even funnier? Apparently, Iron Man's full name is Anthony Edward Stark. (He doesn't like it, though.) (Although I could imagine the guy would cause some confusion and /or diplomatic incidents: he's wearing Lannister colors, while his hero name suggests Ironborn, and his last name is Stark... he'd be in trouble wherever he went, probably.)
"And still, despite the fact that the stranger was clad in the strangest armor he had ever seen, and even if he was as old as Ned and bore no resemblance at all to the head of the house, Jon could feel that Tony was better received by the family in ways he never was.
'Goddamnit.' the bastard muttered viciously under his breath.
'I'm sorry did you say something?' Tony asked, raising a perfectly shaped eyebrow at the tousle-haired young man behind him.
'Nothing,' Jon said casually, all the while praying to the old gods and the new for a wildling to appear and devour the foreign stark alive."
