Every so often, Marvel will do variant covers on a lot of their comics, usually in relation to a movie release. They will soon have a series of variant covers which re imagines Marvel characters as animals. They have not released all the covers but for the ones they have released, there are a couple that feature the Hulk, specifically for Avengers and Avengers World plus the Thunderbolts. I am hoping that the Hulk gets his own also. I also included the Ghost Rider cover because the Ghost Rider as a hamster in a flaming wheel is just too awesome to pass up.
