Apparently this latest animated feature film, Iron Man & Hulk: Heroes United from Marvel will see Iron Man and the Hulk team up to battle villains such as Zzzax, Abomination and more. The Avengers movie will apparently have quite a heavy influence on the relationship between the characters. The portrayal given by Robert Downey Jr and Mark Ruffalo in the movie will be providing a path for the characters in this animated film to follow. Iron Man & Hulk: Heroes United is due to come out in April 2013.
