Henry "Hank" McCoy, known as Beast, is a prominent member of the X-Men. He first appeared in X-Men #1 (1963).

Initially possessing superhuman strength, agility, and intelligence, McCoy underwent a transformative experiment, hoping to revert a secondary mutation. This resulted in his now-iconic simian appearance: blue fur, enhanced senses, and larger hands and feet.

Despite his beastly exterior, McCoy remains a brilliant scientist and intellectual, often serving as the X-Men's resident doctor and technical expert. His vast knowledge spans genetics, biochemistry, and other scientific fields. A staunch advocate for mutant rights, he is sometimes conflicted by his scientific curiosity and the ethical implications of his work.
