"Yes he can, his X-gene made him a Telepath, his disability was a side effect of the same cause."
Nah thats wrong. Xavier originally lost his ability to walk fighting a powerful enemy of the xmen sorry i cant remember his name i'll get bk 2ya on that one lol, after he regained this ability to walk thanks to shiar cloning technology(his original body was implanted by a brood egg) he lost it again fighting the shadow king on muir island
