Xavier in the X-Men film series, and for his prolific stage roles with the Royal Shakespeare Company. Stewart's character, Charles Xavier, is very similar to Picard and himself, "a grand, deep-voiced, bald English guy" aka Professor X, the leader and founder of the X-Men.
Throughout most of his comic book history, Xavier
is paraplegic, although his body houses one of the world's
most powerful mutant minds. As a high-level telepath, Xavier
can read, control, and influence human minds. Stewart has
also since voiced that role as Xavier in 4 video games
including: X-Men Legends, X-Men Legends II, and X-Men: Next
Dimension. Truly he is one of the most powerful telepaths in
the Marvel Universe.
