Robert Downey Jr.'s Tony Stark and Chris Evans' Steve Rogers are heading towards a major fallout in Avengers: Age of Ultron, which will undoubtedly split their team right down the middle. This was evident on two official Avengers 2 posters released yesterday, with Captain America leading his avenging warriors on the first one-sheet, and Iron Man taking charge on the alternate design that arrived later in the day. Now, Marvel and Disney are releasing individual character posters, with the debut one-sheet featuring new art of Robert Downey Jr. as an unmasked hero about to face his greatest challenge.

In Avengers: Age of Ultron, Tony Stark attempts to jumpstart a dormant peacekeeping program. Things soon go awry and Earth's Mightiest Heroes, including Iron Man, Captain America, Thor, The Incredible Hulk, Black Widow and Hawkeye, are put to the ultimate test as the fate of the planet hangs in the balance. As the villainous Ultron emerges, it is up to The Avengers to stop him from enacting his terrible plans, and soon uneasy alliances and unexpected action pave the way for an epic and unique global adventure.

Check it out Iron Man prepares to face two of his greatest enemies: The evil Ultron, which he created. And Steve Rogers, a man out of time with a moral sense Stark will never quite understand. This summer, Marvel promises to deliver the biggest superhero epic of all times. Stay tuned as more character posters are released throughout the week...Who will be unmasked next?
