De acordo com o site , ele superou o bloqueio mental (suas pernas foram consertadas algum tempo antes ) nas questões antes das Guerras Secretas.
Although Professor X theoretically has had the ability to walk for some time now, it was only in the issues of X-Men and New Mutants that took place directly before Secret Wars that he was able to overcome the mental blocks and actually start walking without pain. Additionally, while Storm has been the leader of the field team, the X-Men's first and greatest field leader Cyclops is back in the picture for this series. So there's a lot of debate about who should be leading the team.
De acordo com a entrada da wiki da Marvel , seu corpo foi restaurado (a mente foi transferida para um novo, mais jovem, clone body) em Uncanny X-Men # 167 . Entre 171-175, ele tentou andar, mas sentiu uma dor intensa quando tentou usar as pernas.
Novos Mutantes # 14 é onde ele é mostrado pela primeira vez caminhando, com a revelação aparentemente sendo ele se levantando para dançar com Illyana depois que ela derrotou S'ym. 
Em Edição # 180 , nós o vemos andar e jogar basquete antes é raptado para o Mundo da Batalha no final.
After months of practice, Charles Xavier has managed to beat the psychosomatic feedback his mental powers had created preventing him from walking in his new body. He decides to enjoy this newly acquired ability to playing basket ball.
