Hickman seems to have done his research. He seems to know his X-Men history and he knows the characters. He does know that Jean is a powerhouse. And yet he does not use her. I think his ideas are bolder than his characterization, but there is more going on here. As some have suggested, I think that Xavier is holding Jean back for some reason. Her codename and her costume suggest a regression to her character. At least in HoX/PoX and X-Men. In X-Force she is confident and powerful and versatile, ”able to play melody or harmony, to swing between the brightest and darkest notes”.
I love Jean in X-Force. But she is not a Marvel Girl and the costume doesn’t suit her. She is a true Marvel Woman here. It is like Percy and Hickman are writing two different characters. At least I felt this way until I read Giant Size. That version of Jean could have been written by Percy.
I just don’t get it. Or could it be that when Xavier was shot, something happened to Jean? That if Xavier was somehow holding her back, he lost his control over Jean when he died (for a while), and now the true Jean Grey is returning?
