8. Iron Man 3
A lot of different suit designs ended up in Iron Man 3, including some heavy-duty versions and ones with new paintjobs. Most of the film was spent with the Mk 47, though that malfunctioning suit with lots of shiny gold plates down the front of it. One suit that didnt make it into the movie, and which is far cooler than the Mk 47, is the Grapple Suit designed by Josh Nizzi during the concept art phase. Not only would this version allow Tony to grapple around like hes playing Arkham Asylum, but it also has unique visual touches which could have looked great up on the big screen. The grubby grey and brown look of the suit makes it look battle-worn, while the green touches around the eye slits and the arc reactor add a slightly ominous touch. It looks like a suit worthy of gritty urban warfare, which is infinitely more interesting than a shiny suit that barely works.
