Professor X (Charles Francis Xavier) is a mutant with powerful telepathic abilities. He founded and occasionally led the X-Men, sheltering, and training mutants at the X-Mansion in New York. Xavier promotes peaceful coexistence between humans and mutants, though he later focuses on establishing a mutant nation on Krakoa. His scientific genius led to inventions like Cerebro for tracking mutants. Xavier’s ideology contrasts with that of Magneto, another mutant leader.
