SPOILER WARNING: If you don't wish to know about a possible future plot events for the Marvel Cinematic Universe don't keep reading

One of the big mysteries left in the Marvel Universe is, "What happens to Hulk at the end of Avengers?" Unlike Iron Man, Thor and Captain America, all of whom have solo movies as part of Marvel Studios' Phase Two plans, the story of what happens between Avengers and Avengers 2 won't be chronicled in a film. So what is going on next with the giant green beast and Mark Ruffalo?A source close to the studio has reportedly told Latino-Review that the current plans are to have The Avengers 2 end with the Hulk being launched into space by the cinematic version of the Illuminati and begin the classic Planet Hulk storyline from the comics. For those unaware, the arc begins with Hulk being banished from Earth for being too much of a destructive force. After a journey he crashes on to an alien planet, is enslaved, becomes a gladiator, and then eventually, a hero. What makes the situation interesting is that the story is actually very similar to plot of John Carter, which was a notable flop for Disney last year. The story was previously adapted as a direct-to-video animated film that was released in 2010 (you can watch it on Netflix Streaming now).What's more, the site says that Hulk will return to Earth in The Avengers 3 and the plot of the movie will follow the arc of World War Hulk, which has the character coming back to get revenge on those that sent him away to begin with. Both stories were originally written by Greg Pak.Using Hulk as a main character has been a sincere challenge in the world of live-action films, but Planet Hulk is one of the most celebrated recent Hulk storilines. Can they pull it off? Should they try to pull it off? Let us know your thoughts and feelings about the rumor in the comments section below.
