Is Marvel actually planning to do anything with Nate Grey any time soon? Because he'd probably fit in quite well with the Uncanny X-Men (and would provide yet another layer of bemusement for young Jean) with his unique experience on the whole 'hated and feared' thing. And if nothing else, the cold and sheer mockery his costume would garner would maybe make him actually change the damn thing (I love the character, but he looks ridiculous wandering out shirtless, without shoes, in leather).
I don’t think there are any plans for X-Man at the moment. But only Mike Marts knows for sure.
