Following Professor X's death at the hands of Cyclops in the pages of Avengers Vs. X-Men, Charles Xavier's brain was picked apart by the Red Skull and he's remained dead and gone ever since. Recently, we learned that his consciousness has been imprisoned on the Astral Plane for hundreds of years alongside The Shadow King and the two have spent that time battling each other for supremacy.
Well, the X-Men recently made their way to the Astral Plane to free Xavier but how could he possibly return to the land of the living with no body? Well, Astonishing X-Men #6 took things in a very unexpected direction by revealing that Charles and Fantomex had some sort of agreement and that's led to the former leader of the X-Men now taking control of the French mutant's entire body!
The fact his speech bubbles are the same colour as the Shadow King's may be quite telling as this does seem rather out of character for the good professor! It's feasible he may have gone insane while trapped in the Astral Plane but "X" is clearly very different to Professor X and it remains to be seen whether he'll still be psychic or will just have Fantomex's abilities. What do you guys think of this?
