According to Latino Review on Feb. 4, a revelation has been made that Hulk will be parting ways in the Marvel cinematic universe. The spoiler indicates that in “Avengers 2” he’ll be making his way into space and in “Avengers 3”, Hulk will be taking revenge when he returns to Earth.
Marvel’s recruitment process
Marvel is making strategic strides in mapping out its universe. Their agenda even started with “Iron Man” when Nick Fury approaches Tony Stark about The Avengers Initiative.
Also, the recruitment process continues at the end of “The Incredible Hulk” when Stark approaches General Ross about forming a team. Nick Fury continues further with the unfrozen Captain America as well and even Agent Coulson meets up with Thor after the encounter with Destroyer.
Hulk leaves Earth at the end of “Avengers 2”
Even if "Planet Hulk" or something similar is possible, there's no such movie coming any time soon. "Do I think Hulk can carry a movie and be as entertaining as he was in 'Avengers'? I do believe that. I do believe he absolutely could. We certainly are not even going to attempt that until 'Avengers 2,'" said Feige. "So there's a lot of time to think about it."
Now, with Mark Ruffalo having been lured into signing a six movie deal, he had sealed his career and future for years to come with the ability to star in his own franchise. So it sounds like Ruffalo will be making a smash for the long haul.
The future of Hulk
For those who don’t know where this story will go in the Marvel cinematic universe, phase two is based off the “Planet Hulk” story line where Hulk is fooled by the Illuminati into taking on a mission in space, but was extracted by a worm hole where he finds himself on a planet inhabited by aliens. In phase three, Hulk becomes king of said planet and then returns to Earth in “Avengers 3” to take revenge on the heroes who had exiled him based on comic book story arc of “World War Hulk”.
According to investigative reporter of Latino Review, El Mayimbe, there are no copies of these story arcs to be found anywhere in Manhattan. This just gives an idea how hot Hulk is prior to even having another movie.
