Yes, that's right- IRON PATRIOT IN THE HOUSE!!! THIS IS HUGE! I mean, you're basically looking at another Iron Man armor, but still- it's just so amazing to see, especially when the Iron Patriot was a fairly recent character. I'm assuming this is to keep up with the movie number as well. If you haven't caught on, Iron Man 1 had one Iron Man armor, Iron Man 2 added a second Iron Man armor in Warmachine, and now Iron Man 3 will add the third in the Iron Patriot.
Ok, ok, so maybe you don't know anything about the Iron Patriot. Allow me to fill you in. The Iron Patriot was the main antagonist of the "Dark Reign" arc for Marvel comics. This is why we "assume" the suit to be the villain in the movie. The suit is Norman Osborn's way of taking a psychological jab at the Avengers, sporting the armor with his own team of Dark Avengers. It has been confirmed that Norman Osborn is not behind this armor however. So no, of course we won't have any worries of Dafoe wearing this armor. In this run through, we have James Badge Dale instead. Take a look at this:
So what will James be doing? Well, he'll be playing the role of Eric Savin. This character is better known as "Coldblood", if he's known at all. Not a major Marvel character, but it's important to note that Coldblood is a cyborg. So where this plot will take us is almost guaranteed not to be Comic-book Accurate, but hey- if you wanted those stories just go pick up the comics. It's what makes these movies so good; you get to see things that aren't already in print. Given Marvel's trends, we can almost expect a comic title or two to bring back the Iron Patriot, and it wouldn't surprise me if Coldblood came back as well from his now seven-year hiatus from simply "missing in action" after Marvel's Civil War. We're most excited to see how they'll make this movie, including the Iron Patriot with the other hints and jabs at comic nostalgia in Fin Fang Foom and The Mandarin.
