4. Rocket Raccoon
Marvel StudiosThis might seem crazy, but Rocket Raccoon could quite easily become the flagship character of the Marvel Cinematic Universe. The bizarrely cute and cuddly little mammal - who also happens to possess the skills of a hardened mercenary - already appears to be everyones favourite Guardians of the Galaxy character before the movie has even been released - and it's hard to see that changing any time soon. Hes huggable, but hes also as tough as old boots and he doesnt give a sh*t about anything. He has a giant walking tree as his muscle, he has a tendency to bite and, if hes anything like the comic book version of the character, hes going to be very funny as well. The key factor in his popularity is the fact that kids are going to love him. In spite of the fact that hes an intergalactic mercenary, hes still furry with whiskers and a cute little nose. Consequently, soft toy versions of the character are going to shoot off the shelves of toy stores around the world like hot cakes. Also, don't underestimate the likeability of Bradley Cooper as an actor. He is hot property in Hollywood right now and, even though only his voice and facial movements will be evident in the final movie, fans are undoubtedly going to want more from the star of "The Hangover" franchise.
