Proteus

Kevin MacTaggert, best known as Proteus and also called Mutant X, is a character appearing in American comic books published by Marvel Comics. The character is commonly associated with the X-Men. Kevin was the mutant son of Scottish genetic researcher Moira MacTaggert and politician Joseph MacTaggert. Kevin had reality-warping and possession powers and lived most of his life in forced seclusion at his mother's Muir Island research facility. His attempt to break free and find his father made up a classic 1979–80 The Uncanny X-Men storyline that was adapted in the 1990s X-Men animated series. In 2009, Proteus was ranked as IGN's 77th-greatest villain of all time.
