Professor X (Charles Xavier) (voiced by Cedric Smith) - The founder of the X-Men, Professor Xavier is very similar to his comic book counterpart, and his friendship with Magneto is explored in greater detail during this series. Differing slightly from the comics, Xavier is stated to have lost the use of his legs "battling Magneto" in the episode "Sanctuary" and instead of a wheelchair, he uses an orange hover-chair. He is shown at times to be a lonely man, such as when he sadly watches Moira MacTaggart and Banshee embrace. In the "Phoenix Saga," Xavier's dark side briefly manifests itself.
- Powers: Charles possesses supremely powerful telepathic abilities, allowing him to see peoples' minds or to control their thoughts or actions, though the latter is not used for his personal gain.
