Lord Xavier

Lord Xavier is an alternate reality Charles Xavier and a tyrant ruler of a dimension in which sword and sorcery rule, similar to the Lord of the Rings or other high-fantasy fiction - however when his reality was infiltrated by the X-Men the two would clash and the X-Men would fight against the "Witch King of Gha-No-Shah".
