Professor Charles Xavier, also known as Professor X, is a fictional character in the Marvel Comics universe, and his abilities are subject to the creative decisions made by the writers and creators of the stories. That being said, there are a few reasons why Professor X might not have full control over his own body despite possessing powerful telepathic abilities:
Limitations of his powers: In various comic storylines, it is established that telepathy is an intricate and challenging ability to master. While Professor X is an incredibly powerful telepath, even he has limitations. Controlling one's own mind and body can be much more complex than influencing the thoughts of others, as it requires a deep understanding of one's own consciousness and subconscious.
Mental defenses: To protect themselves from psychic intrusion, individuals in the Marvel Universe can develop mental defenses and barriers. These defenses can make it difficult for telepaths to directly manipulate their own minds, as well as the minds of others.
Ethical considerations: Professor X is depicted as an ethical character who respects the free will and autonomy of others. He may refrain from using his powers to control his own mind and body because he believes in personal agency and the importance of self-control.
Mental health and emotional struggles: Throughout the comics, Professor X is portrayed as a complex character with his own internal conflicts and emotional struggles. His personal experiences, including physical disabilities (such as being paralyzed from the waist down), may contribute to his inability or reluctance to fully control his own body through telepathy.
Plot and character development: The limitations of Professor X's powers serve to create tension and challenges in the storytelling. Writers often use these limitations to develop character arcs and drive the plot forward, making the narrative more compelling.
It's important to remember that comic book characters, including Professor X, are fictional creations designed to tell captivating stories. As such, their abilities, weaknesses, and struggles are shaped by the creative vision of the writers and the broader narrative context within the Marvel Universe.
