Beast (Henry Philip "Hank" McCoy) is a fictional superhero appearing in American comic books published by Marvel Comics and is a founding member of the X-Men. Originally called "The Beast", the character was introduced as a mutant possessing ape-like superhuman physical strength and agility, oversize hands and feet, a genius-level intellect, and an otherwise normal appearance. Eventually being referred to simply as "Beast", Hank McCoy underwent progressive physiological transformations, permanently gaining animalistic physical characteristics. These include blue fur, feline facial features, pointed ears, fangs, and claws. Beast's physical strength and senses increased to even greater levels.
