One of the big questions that has been hanging around the Marvel Cinematic Universe since its first year of existence has been, "What do we do with Hulk?" The Incredible Hulk was viewed as an under-performer compared to other heroes in the Marvel stable, and while the character was certainly a standout in Joss Whedon's The Avengers, there was no substantial role for him found in Phase Two. Stories have been stirring lately about what the studio could be planning for the giant green monster in Phase Three, and now a new interesting bit of speculation has hit the web.
Fair Warning: What lies ahead could be some very big spoilers for The Avengers: Age of Ultron. We're not 100% sure that the rumors and speculation in this story are true - and it very well could not be - but if you don't want to take the risk then I would recommend heading back over here.
