9. War Machine
While he won't have a starring role in Avengers: Age Of Ultron, it's believed that War Machine will have become an official member of The Avengers since the events of Iron Man 3 (The Falcon will also be in the movie, but likely on the hunt for Bucky while Cap is busy). However, does the team really need this armed up former Iron Patriot ally on the roster? Rhodey has proven himself a number of times now to be fair, and the fire power his suit has will no doubt come in handy when the Avengers are squaring off with an almost endless wave of Ultron's drones. However, his lack of experience with the team and the fact that his armour isn't anywhere near the level of Tony Stark's puts him at a disadvantage.
