Avengers: Age Of Ultron - 25 Moments From The New Trailer You Need To See

2. Iron Man In The Hulkbuster

After seeing the Hulkbuster attacking the Hulk in the first trailer, the general opinion of fans was that Ultron was probably remotely controlling the armour to combat the threat of the big green hero. However, given what was shown in this new trailer, it does actually seem as though Tony Stark is piloting it. This obviously brings up the question of why Stark feels the Hulk needs taking down and certainly hints towards a future storyline that would see the Hulk being seen as a problem that needs dealing with. Planet Hulk in Phase 4, anyone?
