1. Savage Hulk
A Funko Pop! advertisement seemingly revealed a gigantic spoiler from Avengers: Age Of Ultron, and while some fans argued that the grey 'Savage Hulk' pictured above was likely just a variant, the fact that Marvel recalled the comic books it was featured on the back of obviously means it shouldn't have been seen. Only the green version of the iconic character has been featured on the big screen so far, but it looks like he'll undergo a transformation. Based on those red eyes and the fact that he also had them in the trailer while battling Iron Man's Hulkbuster, the Hulk becoming the grey Savage Hulk will likely come as a result of the Scarlet Witch's sorcery. Just how much it will change the character remains to be seen - will he be grey for only a moment, or will this create an entirely new Hulk? Maybe he's so out of control, Iron Man sends him into outer space. If so, that would perfectly set up that long rumoured Planet Hulk movie anyway...
