Just Saw Iron Man 3

[Newt]

Also the lack of War Machine annoyed me, I mean isn't the Iron Patriot a
suit worn by the guy who is the Green Goblin? Or have I got that
completely wrong?

Yes, Norman Osborn and Obidiah Stane's son keep messing with Stark Industries and they got a hold of the Iron Patriot armor. Iron Patriot was used for the Dark Avengers, which was somewhat amusing.

I don't know enough about Marvel for you to take the above as anything more than a grain of salt.

Phoenix, if you'd like to read comics(Like Extremis) an easy place to start is Barnes and Noble. They have a comic section, and if they don't have what you want, you can ask them to order it for you. Extremis is collected in a nice paperback, making it easy to gain access to and read.
