Also known as, The Beast, and a member of the X-Men.
Dr. Henry "Hank" McCoy, also known as Beast, was created by Stan Lee and Jack Kirby and first appeared in the X-Men #1 comic book. Hank is a brilliant scientist and serves both as the X-Men's doctor as well as reference and political liaison due to his intelligence. Hank's powers is to transform into an ape like animal with immense physical strength, this transformation eventually becomes more and more permanent, Hank still retains his previous self.
The X-Men first appeared in animated television shows as the Marvel brand of superheroes became more and more popular. The first was called The Marvel Super Heroes which aired an adventure of the Marvel heroes, once per day, following a different superhero each day. The original X-Men team, Beast included, appeared as guests.
It wasn't until 1992 that the X-Men got their own animated series called X-Men: The Animated Series. Beast was voiced by George Buza throughout the series. In the very first season Beast was detained after the X-Men raided the Mutant Control Agency. Beast refused to be broken out and stood in court like any other person would to prove that mutants could be treated like everyone else. Beast and the X-Men are able to eventually convince the right people that mutants can be good and Beast gets a full pardon. The X-Men also were apart of a crossover briefly with the Spider-Man animated season which was also popular at the time.
The next major installment of the X-Men was the animated series called X-Men Evolution. The series focuses on the X-Men before they were adults and even as Professor Xavier gathered them into the team. Beast was voiced by Michael Kopsa and was not serving the X-Men at the time, despite being approached by Xavier to join Beast continued with his life to be a chemistry and gym teacher. Beast was able to create his own serum that assisted in his management of his mutation preventing any sudden transformations. Eventually the serum wasn't enough and Hank would transform suddenly into Beast which would eventually become permanent. Unable to return to his previous life as a teacher, Beast joined Xavier's school and would teach new students there.
In the newest series, Wolverine and the X-Men, Beats is voiced by Fred Tatasciore. In this version is a much bigger part of the series. After an explosion destroys the X-Mansion and Xavier disappears, Beast spends his time in the basement researching the cause of the explosion and the possible whereabouts of Xavier. Beast is completely unable to transform into his human form and stays Beast throughout.
Beast was originally going to appear in the first X-Men movie but after problems with the effects and make-up was taken out. George Buza, who was his voice in the animated series, makes a brief cameo in the movie.
Beast was again supposed to make an appearance in the second X-Men movie, X2: X-Men United, but was again taken out because the filmmakers already had too many characters. Hank McCoy on the other hand is seen, played by Steve Bacic, and is shown as an authority about human mutations.
Finally in X-Men: The Last Stand, Kelsey Grammer plays Beast and is established as one of the original X-Men. He is though to have graduated from the Xavier Institute and moved on to become involved in mutant politics eventually becoming the Secretary on Mutant Affairs in the presidential cabinet.
Hank is apart of the forefront of the possible formation of a cure from the mutant Leech, who is able to permanently take other mutants powers, similar to Rogue's powers. Little to Beast's knowledge, the cure has been fully weaponized. Once Beast realizes this he resigns his post and falls in line with the X-Men once again. When Magneto and his brotherhood of mutants assault Alcatraz Island, where the cure is being made, Beast goes along with the X-Men in order to protect the island.
The X-Men are able to fight off the brotherhood and even save Leech, Beast is the one who stops Magneto by injecting him with several doses of the cure. After the attack Beast is offered the position of US ambassador to the UN but turns it down and returns to the Institute t be a teacher.
In the newest X-Men movie, X-Men: First Class, Beast was portrayed by Nicholas Hoult. He begins as the young Dr Henry McCoy whom is outed as a mutant by Charles Xavier when he meets him at Division X. McCoy's mutation has so far only manifested itself in the form of superior intellect and prehensile feet but after he goes to live at the mutant academy Xavier teaches him to use his feet to run at high speed. McCoy is ashamed of his appearance and uses his intelligence to work on a cure that would allow him to maintain his powers without being physically deformed. When the cure is completed McCoy injects it, only to find that it in fact spreads the deformation that affects his feet across his entire body, leaving him in his more familiar beat form. McCoy is upset about his appearance and takes offense at Erik Lensherr's compliments. Despite his problems with his appearance, the fact that he designed the plane means he is the only one who can fly it and so he pilots it and the other mutants to cuba to fight Sebastian Shaw. He uses his newly acquired physical strength to help defeat Azazel and as such is crucial in the final battle. After Xavier is shot by Lensherr he returns to the academy where he will live out the rest of his life.
Dr. McCoy is a brilliant and even wise scientist, with his intellect he spent a lot of his life fighting for mutant rights and as an example that mutants could be tame. As Beast he retained his genius especially as the change between Hank and Beats became more and more permanent. He is best recognized by his blue fur and ape-like stature as well as glasses because eyesight problems are forever.
