Iron Man 3 win from ActionFigurePics.com were these two 'Assemblers:' War Machine and the Mark 42 Iron Man armor. The first thing I noticed when I got these two next to each other was that War Machine is much bulkier than Mark 42. I'm surprised they did that, especially since interchangeability is the theme for this line.
The Assemblers gimmick is clever and well executed, but I don't think they are making enough armors in this line to make it truly worthwhile. If there were ten or more armors you could make zillions of cool creations, but to my knowledge there are only three: War Machine, Mark 42 and Iron Patriot.
But I'm not complaining, free toys are free toys, and if you're an Iron Man fan you could have been treated a lot worse by the toy companies. In my experience the third film in a trilogy usually gets the worst of it when it comes to toys, be it through repaints or rushed, lazy product. At least these are new and nice representations of the on film armors!
