First things first, these don't really exist. At the moment these are conceptual, and given Marvel's continued insistence that their properties are kid friendly, I wouldn't ever expect these to see the light of day in any real capacity. Nevertheless, these are fairly creative works of art by Hungarian artist Balazs Sarmai and are worth admiring. Let's do that, shall we?
So Hulk is the only one I take issue with. That thing should be huge. Like huge, huge...
Yeah, like that. But in green.
Also, not to rain on this guy's parade, but Doc Johnson beat them to the unlicensed versions already, so he'd better hope that Marvel loosens up.
