Beast (Marvel Comics)

Beast is a superhero appearing in American comic books published by Marvel Comics and is a founding member of the X-Men. The character was introduced as a mutant possessing ape-like superhuman physical strength and agility, oversized hands and feet, a genius-level intellect, and otherwise normal appearance and speech. Eventually being referred to simply as "Beast", Dr. Henry Philip "Hank" McCoy underwent progressive physiological transformations, gaining animalistic physical characteristics. These include blue fur, both simian and feline facial features, pointed ears, fangs, and claws. Beast's physical strength and senses increased to even greater levels.
Despite Hank McCoy's feral appearance, he is depicted as a brilliant, well-educated man in the arts and sciences, known for his witty sense of humor, and characteristically uses barbed witticisms with long words and intellectual references to distract his foes. He is a world authority on biochemistry and genetics, the X-Men's medical doctor, and the science and mathematics instructor at the Xavier Institute (the X-Men's headquarters and school for young mutants). He is also a mutant political activist, campaigning against society's bigotry and discrimination against mutants. While fighting his own bestial instincts and fears of social rejection, Beast dedicates his physical and mental gifts to the creation of a better world for man and mutant.
One of the original X-Men, Beast has appeared regularly in X-Men-related comics since his debut. He has also been a member of the Avengers and Defenders. Various storylines over the years have hinted that Beast has capacity to become a supervillain; his alternative universe counterpart Dark Beast was a recurring character in 2000s and 2010s comics. During the Krakoan Age 2020s X-Men storylines, Beast assumes an antagonistic role to the other X-Men, becoming an outright villain. At the end of the Krakoan Age, the original Beast dies in an act of last minute redemption, and is replaced by his younger clone whose memories stop short of the events which corrupted the original Beast.
The character has also appeared in media adaptations, including animated TV series and feature films. Beast has been a cast member in all X-Men animated series, most notably in X-Men: The Animated Series (1992–97), voiced by George Buza, a role he reprised in the cartoon's revival X-Men '97 (2024–present). Kelsey Grammer played the Beast in X-Men: The Last Stand (2006), while Nicholas Hoult portrayed a younger version of the character in X-Men: First Class (2011). Both Hoult and Grammer reprised their roles in X-Men: Days of Future Past (2014). Hoult reprised the role in X-Men: Apocalypse (2016), Deadpool 2 (2018) and Dark Phoenix (2019), while Grammer reprised the role in the Marvel Cinematic Universe (MCU) films The Marvels (2023) and Avengers: Doomsday (2026).
Created by writer Stan Lee and artist and co-writer Jack Kirby, the character first appeared in X-Men #1 (September 1963). Stan Lee writes in the foreword to X-Men: The Ultimate Guide that he made Beast the most articulate, eloquent, and well-read of the X-Men to contrast with his brutish exterior. Further, the book opines that the Werner Roth–Roy Thomas team garnered admiration for their "appealing and sensitive characterizations of the original X-Men". Roth, under the alias Jay Gavin, had taken over for Kirby fully by issue #18, and Thomas was a new talent. Beast was given an individualized, colorful new costume, along with the rest of the X-Men by issue #39 to attract new readers. During Jim Steranko's tenure, which added "exciting art", Roth returned, working with Neal Adams who blended Kirby's style with "realism, idealized beauty, and epic grandeur".
In Amazing Adventures vol. 2 #11 (March 1972), written by Gerry Conway and drawn by Tom Sutton, Beast underwent a radical change and mutated into his now familiar furry, blue (originally grey) appearance. The concept originated with Roy Thomas, an effort to make the character more visibly striking, and Beast also became more werewolf-like to capitalize on the success of Werewolf by Night. Steve Englehart, who wrote the remainder of the Beast's short-lived spotlight in Amazing Adventures, emphasized the character's wit rather than the tragedy of his transformation into a more monstrous form, reasoning that the Beast's intelligence and sense of humor would allow him to see his misfortune in perspective. Over the next decade the Beast would appear on the roster of several teams in titles ranging from The Avengers to The Defenders to X-Factor. It was not until 1991, in X-Factor #70/X-Men #1, that the Beast finally returned to the X-Men.
Englehart later said that he added the Beast to the Avengers roster because he wanted to write the character again and thought his funny, down-to-earth personality would make him a good foil for Moondragon. Succeeding writers of The Avengers similarly found that the character's lightheartedness made a good balance to the team's generally serious tone, resulting in the Beast's run in The Avengers outlasting his earlier run in X-Men. His friendship with fellow Avenger Wonder Man would likewise come to eclipse his friendship with X-Man Iceman for the comics fandom. The Avengers #137 (July 1975) debuted the Beast's catchphrase, "Oh, my stars and garters," and The Avengers #164 (October 1977) was the first to depict him as a sex symbol, a take which writer Jim Shooter said resulted in very positive mail from female readers in particular.
Beast cured the Legacy Virus in The Uncanny X-Men #390 (2001), and in X-Treme X-Men #3 (2001) he experienced a further mutation into a feline being, first shown in the introduction to New X-Men (June, 2001), by Frank Quitely and Grant Morrison. As evidenced on the back cover of X-Treme X-Men Chris Claremont, writer of that series in addition to both The Uncanny X-Men (for sixteen consecutive years) and X-Factor, contributed much to the Beast's characterization. Citing Claremont as inspiration for his run on New X-Men, Morrison explains Beast as a "brilliant, witty bipolar scientist". Morrison continues, "I saw Henry McCoy as an incredibly clever, witty, cultured, well-traveled, experienced, well-read character so I brought out those parts of his personality which seemed to me to fit the profiles of the smartest and most worldly people I know—his sense of humor is dark and oblique. He's obviously quite clearly bipolar and swings between manic excitement and ghastly self-doubt. He has no dark secrets, however, and nothing to hide."
Joss Whedon's "Astonishing X-Men: Gifted" story arc featured a "mutant cure" designed by Indian Benetech scientist Dr. Kavita Rao, and the prospect of "real" humanity arouses the interest of a heavily mutated Beast, who visits Rao only to discover that the drug is the product of illegal human experimentation on an unknown victim. The idea of a mutant cure, which had previously appeared in the 1992 animated series, was also the basis of the X-Men: The Last Stand movie plot and the series was even made into a motion comic. IGN called the arc focusing on Beast "best X-Men run in a decade" and lauded Whedon for flawless character dynamics. According to BusinessWeek, Beast is listed as one of the top ten most intelligent fictional characters in American comics.
Beast appeared as a regular character throughout the 2010–2013 Secret Avengers series, from issue #1 (July 2010) through its final issue #37 (March 2013).
In X-Men Legends Vol. 2 #1-2 (2022), taking place between The Incredible Hulk #181 - 182 and Giant Size X-Men #1 starring Wolverine, it is revealed that Beast was responsible for the existence of Wolverine's will-be iconic X-Men mask, when Beast was manipulated by Mesmero into his amnesiac masked servant, Wildlife.
Henry Philip "Hank" McCoy was born in Dundee, Illinois, in the United States, to Norton and Edna McCoy. His father, Norton McCoy, is employed at a local nuclear power plant before Henry's birth and was once exposed to intense nuclear radiation, which appears to have caused his son's mutation. Hank is born with a vast intellect, unusually long arms and legs, and unusually large hands and feet—a rare although not unique case of mutant powers manifesting before puberty. His bodily proportions are comparable to those of a gorilla, and later stories reveal his nickname in school was "Magilla Gorilla".
Henry's mutation more fully manifests during adolescence, providing greater strength and agility, and although his powers allow him to briefly excel in athletics during his remaining time at school, he soon attracts the animosity of his fellow students and other non-mutant humans. After defeating the villain Conquistador with the assistance of some X-Men, Hank joins the group and begins studying at Professor Charles Xavier's Xavier's School for Gifted Youngsters.
Henry recognizes the opportunities such an institution can offer him and accepts the invitation. He finds the school both a fountain of scientific knowledge and a place of sanctuary. There he is introduced to the X-Men, who accept him into their ranks and give him the codename Beast. Alongside workouts in the Danger Room, under Xavier's tutelage, he studies subjects ranging from differential equations to Proust.
With the rest of the X-Men on their first field mission, he battles Magneto for the first time, and later Magneto's Brotherhood of Evil Mutants. He became stressed because he had to keep a secret identity while in the X-Men team, so he briefly left the team to become a professional wrestler. While he was a professional wrestler he met Unus the Untouchable, and helped the X-Men build a directed-energy weapon to make Unus completely untouchable, resulting in Unus not being able to feed himself. Beast then rejoined the X-Men team. With the team, he also visits the Savage Land, and meets Ka-Zar. Beast battles the Juggernaut, but he is badly hurt. He subsequently fights the Sentinels with the X-Men, and he and Iceman battle the Maha Yogi.
Hank is the first to leave the X-Men. He becomes a research scientist at the Brand Corporation, a genetics research facility. His assistant, Linda Donaldson, becomes his girlfriend. Hank isolates a "hormonal extract" allowing anyone to become a mutant for a short period of time, and uses the mutagenic serum on himself to disguise his appearance while foiling an attempt to steal his research. He waits too long to reverse the process, leaving him permanently transformed. He grows grey fur, which later turns blue, all over his body and acquires pointed ears, elongated canine teeth, claws, the ability to run on walls and ceilings like a spider, enhanced senses, an accelerated healing factor, and a feral side he struggles to control. He briefly joins the Brotherhood of Evil Mutants when Mastermind wipes out his memory, but quickly recovers. When Beast is wounded, he is aided by Patsy Walker, and then reunited with his old girlfriend, Vera Cantor. He fears that his furry form will repulse others, but finds that many women are attracted to his hirsuteness. Back at Brand Laboratories, he discovers his girlfriend Linda Donaldson is an agent of the criminal Secret Empire, and they break up.
Not long after this transformation, Beast is recruited to join the Avengers as a provisional member. He is later granted full Avengers membership and remains a member for many years, becoming a close friend of Wonder Man. He leaves the team periodically to rejoin the X-Men during times of need (such as "The Dark Phoenix Saga"). Beast returns to the Avengers each time, but eventually leaves so that the team, which has a six-member limit at the time, can be filled out by new recruits.
He later joins the Defenders, stays with the team to organize as the "new" Defenders, and is one of the final surviving members at the time of its first disbandment as a result of the battle with Moondragon and the Dragon of the Moon. Beast and fellow surviving Defenders members Angel and Iceman are contacted shortly after by Cyclops and Marvel Girl (Jean Grey) to form a new group, X-Factor.
With X-Factor, Beast rejoins the original members of the X-Men, and is again reunited with Vera Cantor. Beast starts out in his furred form, but on their second mission, he is captured by Tower. He is delivered to Carl Maddicks and used in an attempt to develop a cure for mutancy, which has rendered Maddicks' son, Artie, mute. Maddicks develops a serum based on McCoy's original serum, and tests it on Beast. Hank is also subjected to chemotherapy and radiation, and has a cardiac arrest. X-Factor arrives on the scene and saves Hank, but not before he was injected with the serum. When the bandages around his face are removed, he is revealed to have lost his blue fur. This helps in X-Factor's cover as normal humans who are mutant hunters for hire (though they actually help the mutants they capture). When they see the need for their powers, they get new costumes similar to their old X-Men costumes, and call themselves the X-Terminators, posing as renegade mutants. Beast wears a mask as he did originally, since he now looks human again.
Eventually X-Factor clashes with the ancient mutant Apocalypse after Angel loses his wings in a battle and shortly after goes missing. Apocalypse turns Angel into Death, the most powerful of his four Horsemen of Apocalypse. During the battle, Beast is touched by the Horseman Pestilence, whose touch usually causes incredible pain and viral infection. The infection interacts with the recent serum treatment of Maddicks, and instead of killing him, Hank is affected in such a way that every time he uses his superhuman strength, his intelligence decreases. Though the battle is won, it comes at the cost of Hank's decreasing intelligence and Angel's humanity, which would not return for a time. Hank's condition worsens for weeks. He even openly talks to Trish Tilby, a reporter, not realizing she might use the information on TV. Out of respect for Hank's situation, Trish does not mention his name when she reports about X-Factor's recent battles, only that one of them lost his intellect while heroically defending New York. Beast is still hurt by her using the information at all, but she is able to convince him that she meant well.
X-Factor finally ends their charade and are hailed as heroes, and they then don costumes similar to their previous X-Terminator costumes. When Hank's mind is nothing more than that of a child, he intercepts a mutant called Infectia who is trying to kiss Iceman. Infectia has the ability to manipulate molecular structures through touch, creating mutated "monsters". When she kisses Beast, he becomes feverish and begins switching back and forth between his normal and furred forms. Finally, he stabilizes in his furry appearance, keeps his intelligence, and has more strength than ever.
Hank soon resumes wearing his old costume, but now no longer has need for a mask. During the events of Inferno, Beast, along with the rest of X-Factor team up with the X-Men and various other heroes to fight the evil forces invading the city; eventually, they manage to stop a portal between Limbo and Earth from remaining open and peace returns for the survivors. Soon after Inferno ends, the X-Tinction Agenda takes place where Genosha wants to punish various mutants for war crimes on their island. Here, Beast plays yet another key role. Shortly after the crisis ends, X-Factor switches costumes once more; Cyclops, Jean, and Iceman all wear identical costumes, while Beast returns to wearing trunks, and Archangel sticks to his old costume he received from Apocalypse.
Towards the end of this iteration of X-Factor, they battle the Shadow King during the Muir Island Saga. The final battle leaves Professor Xavier disabled again, which results in X-Factor rejoining the X-Men.
One of Beast's greatest challenges emerges with Stryfe's fatal Legacy Virus. Hank is already despondent, as he is turning thirty and questions his life accomplishments. His frustrations are further compounded when Professor Xavier and Moira MacTaggert did not ask for his assistance with the Legacy research, but it turns out Xavier is just giving him his privacy. Perusing their data, Hank learns the problem is more difficult than he had initially imagined. Hank has always believed that, given time, he could solve any problem; the Legacy Virus becomes his obsession. He goes as far as making an unethical decision in giving Mister Sinister information on the virus, since he has more resources and fewer morals to inhibit him.
A turning point comes when Dark Beast finishes some of the formula, occasionally prying more information from Hank whom he imprisoned and replaces for a while. The most critical step toward a solution (other than when Beast individually finds the cure without acknowledgement) comes when Dr. MacTaggert discovers Mystique's irresponsible manipulation of virus strains. The cure is incomplete and it takes Beast to design the final cure. Based on Moira's notes, Beast concocts the anti-virus to much elation, but when it is revealed that its use requires a mutant to die, Colossus chooses to sacrifice his life to release the remedy.
After mourning the loss of a teammate, Hank briefly leaves the school with Storm and her X-Treme X-Men team in search of Destiny's diaries. After an attack by Vargas that leaves Psylocke dead, Beast is gravely injured and returns to the institute.
As the world experiences a mutant baby boom, much of the mutant community seemingly begins experiencing "secondary mutations", often taking the form of additional or enhanced abilities. In the aftermath of Vargas' attack, Beast's secondary mutation is "jumpstarted" due to the powers of teammate Sage. The further mutation causes Beast to develop a more feline physique, to which he initially has some trouble adapting. A psychic attack by the genocidal Cassandra Nova leaves Beast humiliated, badly beaten (by the controlled body of his friend Beak) and haunted by the possibility that his new form is simply a step in a continuous state of devolution. Additionally, the alteration in form causes his long-time girlfriend, Trish Tilby, to break up with him after being accused of bestiality in the media. Over time, Beast strikes up a strong friendship with Emma Frost, in one incident bringing her flowers to cheer her up. He finds her diamond form shattered into thousands of pieces and spends some time putting her back together. With a final jolt of psionic energy from Jean Grey, Frost returns to life.
Beast later uncovers what seems to be a female mutant with feline features, like his situation. This raises hopes for him, until he discovers it is not a mutant human that looks like a cat, it is a mutant cat who looks like a human. Either way, the creature is at the limit of her life and Beast allows her to leave the X-Mansion to die quietly in a spot she finds comfortable.
When news of a "cure" that would reverse mutations suddenly arises, Beast finds himself seriously considering taking it so he can once again appear human. Hank eventually decides against it after vigorous "urging" by fellow team member Wolverine, as it would send out a negative message to other mutants if an X-Man were to take the cure. After learning that the cure was developed by fellow geneticist Kavita Rao through experimentation on mutant corpses—as well as on the revived X-Man Colossus—Beast helps take down Rao's operation. When the villainous Hellfire Club attacks the X-Men, Cassandra Nova telepathically strips away Beast's higher human consciousness, leaving him with only his animal instincts. After he hunts Wolverine around campus (and even eats his leg), a student named Blindfold faces him down with a device he and Xavier had built in case his consciousness was ever lost. The device is a high-powered sensory stimulant in the form of a ball of string, which Beast had alluded to as being his greatest fear. Once restored, he is quick to put on a suit and tie and help Wolverine with a hyper-magnetic device. He, along with his teammates, are taken from the Mansion by the government agency S.W.O.R.D. and airlifted to the alien Breakworld.
When a Civil War breaks out among Marvel's superheroes, Beast, along with the other X-Men, assumes a neutral stance. Beast was not a particular fan of the policy and secretly violates his stance by providing Spider-Man with a holographic disguise to enable him to continue teaching at Midtown High after his secret identity has been exposed. Despite his personal feelings about the Superhuman Registration Act, Beast enlists his services to the Initiative program after the war's end, to assist in the training of the next generation of superheroes.
The X-Men and various other mutants attend the funeral of a young mutant boy named Matt Landru who has been killed in a road traffic accident and muse on what this means for mutant-kind. Beast plans to find a way to reverse M-Day. Despite the 'aid' of his other self (the Dark Beast), along with exploring such diverse avenues of investigation as analysis of alternate timelines or an attempt to track down the Scarlet Witch, he is unsuccessful in his research, but the final part shows him holding a child wearing a three-eyed smiley face shirt saying "Evolution" on it as a promotion of the Messiah Complex.
Beast is shown helping Professor X repair Cerebro when the X-Men are tracking down the child with the X-Gene. Beast is later seen at the Mansion when it is attacked by the Sentinels, who have been taken over by an unknown person. When Iceman arrives at the school with the New X-Men, Beast works with Prodigy and is able to stabilize the mortally wounded Hellion, as well as the other New X-Men and X-Men injured in their battles with the Purifiers and the Marauders, respectively. He is later present during the battle on Muir Island and is among the first to reach Professor Xavier after he is accidentally shot by Bishop. Xavier's body soon disappears.
In the aftermath, Cyclops has sent Beast to search for Professor Xavier, whose status is unknown by the X-Men. Beast is also seen closing down the ruins of the X-Mansion and taking Martha Johansson with him.
Beast is seen as part of the team setting up a new X-Men headquarters in San Francisco, California. He is working closely with Cyclops, Emma Frost, and the rookie X-Man, Armor. He is also still seeing Abigail Brand, who requests that he take a weekend off from the X-Men so that she can 'tamper with him extensively'. He helps Tabitha Smith, teaching the young and flippant woman to use research instead of brutal strength to fight her enemy, a mutant with sedation powers called Nuwa. He and Warren go to Buenos Aires to recruit Doctor Nemesis to help the X-Men save the Mutant race. Only after they stop tube-grown super Nazis, does Nemesis agree. They also recruit Madison Jeffries. Together, they created a time travel device so that they could travel into the future and retrieve the mutant Messiah. However, because they created a device for time travel in so little time, the side-effect of the device is that the user's biology breaks down upon entering the future, so it will automatically bring the person back in thirty-two and a half hours.
Beast discovers that the Super-Skrulls with X-Men abilities can be infected with the Legacy Virus. Despite his ethical protests to the contrary, Cyclops decides to use it on them, offering the antidote in return for the Skrulls' retreat.
To save mutantkind from the effects of M-Day, Beast and Angel had to gather a team of specialists to help them. They gathered Madison Jeffries, Yuriko Takiguchi, and Doctor Nemesis. They then returned to Graymalkin Industries to meet their final member Dr. Kavita Rao (who was formerly trying to cure mutation). Beast and the X-Club traveled back to 1906 to find Doctor Nemesis's parents and discover the origins of modern mutation. During the mission, they also fought an early version of a Sentinel created by the Hellfire Club, and inadvertently caused the San Francisco earthquake. When they returned to the present, they found that their DNA evidence had been buried beneath where the Dreaming Celestial was standing in the park.
After being captured, Beast became a test subject for the Omega Machine (designed by Dark Beast to eradicate mutant powers and place them in Weapon Omega) while being held prisoner on Alcatraz Island by Norman Osborn, along with Professor X. Beast is shown getting weaker and mentions losing his claws while hooked up to the machine. Beast was rescued by the X-Men, and later recuperated from his injuries. Later, he spoke at the funeral of Yuriko Takiguchi when Magneto had arrived. Beast seemed increasingly disillusioned with Cyclops' leadership and methods, such as allowing Magneto to become a member to his time under torture under the Dark Beast. This resulted in Beast leaving the X-Men.
After leaving the X-Men, Beast opted to join his current girlfriend Agent Abigail Brand as a member of S.W.O.R.D. However, shortly after joining her in space, Brand's co-commander, Henry Peter Gyrich (hired by Norman Osborn) begins to round-up the aliens residing on Earth, in a xenophobic attempt at avoiding another Secret Invasion. As a result of Henry's plan, he has even made moves against Brand, resulting in her, Beast, and the dragon Lockheed, becoming fugitives from S.W.O.R.D. and attempting to overthrow Gyrich.
Beast later returns in an issue of Uncanny X-Men to attend the funeral of his friend and teammate, Kurt Wagner (Nightcrawler) where he confronts Scott Summers and blames Kurt's death on Scott's increasingly militant and extremist attitude to protecting the mutant species at all costs (even at the cost of sacrificing his friends to do so). Despite his issues with Cyclops, Beast remains on Utopia to help deal with the attacks being made by Bastion. Following Bastion's defeat at the hands of Hope Summers, Henry again departs Utopia.
Hank appears as part of Steve Rogers' Secret Avengers team. He goes with the covert ops squad on their mission to Mars, and assisted the team in helping Shang-Chi. He also played a crucial part in the capture, interrogation, and "un-brainwashing" of John Steele.
After the separation of the X-Men into two teams, Beast is in the team that goes with Wolverine to open The Jean Grey School for Higher Learning in Westchester County, New York.
During the Avengers vs. X-Men mini-series, Beast sides with the Avengers to investigate and stop the Phoenix Force's return to Earth. Hank joins the team of Avengers sent to halt the Phoenix Force's return to Earth, but later temporarily resigns from the Avengers in protest against their efforts to stop the 'Phoenix Five'—the five X-Men who have received the power of the Phoenix Force—as their actions appear to initially be benevolent. He returns to aid the Avengers and the X-Men when Cyclops and Emma Frost begin to be corrupted by the Phoenix's power.
In the aftermath of the Phoenix War, Cyclops now actively strikes out at government organizations and holds mutants prisoner, with the X-Men unwilling to actively fight him as they fear the subsequent mutant civil war that might result. Beast, who is apparently dying due to side-effects of his secondary artificially-accelerated mutation, stumbles upon a solution after a chance comment from Iceman to the effect that the Cyclops they knew when they were young would not tolerate his present self's actions. Beast travels back in time to the early days of the Xavier Institute to bring the original five X-Men from that period into the future, hoping that Scott's past self will be able to convince his present self to stand down.
Beast lapses into a coma shortly after bringing the team into the present, and Jean's telepathy, which is artificially accelerated by the trauma of her trip to the future and witnessing what Scott has become, manages to connect the minds of the two Hanks. This allows the younger Hank to spot a mistake in his future self's calculations and stabilize his physiology by reverting to a blue-furred ape-like state again where this form is bald and has no head hair aside from the blue fur covering his whole body. The young X-Men decide to stay in the present and become the All-New X-Men, except for Angel, who joins Cyclops' Uncanny X-Men.
After Cyclops goes to Muir Island and discovers that all of the mutants died painful deaths, he calls Beast to do a diagnosis and Beast discovers that somehow that the Terrigen cloud, the substance that gives Inhumans their powers, has become toxic towards mutants after mixing with the atmosphere changed its structure. Hoping to bridge Inhuman and Mutant relations in light of this new conflict, Beast works with the Inhumans to find a way to make the Terrigen cloud safe for mutants while making sure it remains suitable for Inhuman powers. He becomes a trusted ally to the Inhumans and joins their counsel.
When the present Beast realizes that he cannot find a cure for the Terrigen cloud, he visits the rest of the mutants and advises them that the best course of action is for all mutants to leave Earth, but his teammates object and imprison him before he can warn the Inhumans that war is coming. However, after learning what the cloud will do to mutants, Medusa activates a generator to destroy the Terrigen cloud, leaving Emma to be branded a traitor for her false claims inform about Cyclops's true death to manipulate the X-Men into destroying the Inhumans. Havok helps Emma to escape for the sake of his brother's memory, while Beast and his remaining teammates make up, all regretting what their lives have come to ever since discovering that the Terrigen could kill them.
During the "Empyre" storyline, Magik brings Opal of Hordeculture to Krakoa and gives her to Beast so that they can work on a potion containing the toxic material from the black walnut tree. Beast and Opal succeed in making the formula. Using Hordeculture's technology, Beast revives Explodey Boy so that he can confront his zombie counterpart.
It is possible that Beast's mutation is a result of genetic atavism. However, he also possesses neotenous characteristics, which may explain him having a genius-level intellect despite his animal physique. He also possesses superhuman strength, speed and agility. He is an excellent hand-to-hand combatant, employing a unique style of acrobatic combat, from combat training he received at Professor Xavier's and coaching from Captain America.
Originally, Hank McCoy retains the basic features of a normal human alongside a generally simian physiology (e.g., elongated limbs and enlarged extremities) equivalent to that of a great ape. This mutation gives him superhuman strength, speed, reflexes, agility, flexibility, dexterity, coordination, balance, and endurance. Hank is equally dexterous with all four limbs; able to perform tasks with his feet or hands with equal ease. Because of his talents and training, Beast can outperform any Olympic-level athlete, contorting his body and performing aerial feats gracefully. His strength and dexterity allow him to climb vertical surfaces with just his hands or feet, jump great distances and survive falls that would kill any ordinary person. He also possesses enhanced senses and can track people for great distances over open terrain and his feet are sensitive enough to detect electronic signals (from bombs, listening devices, etc.) through solid walls and floors. Later, he drank an experimental solution of his own making and mutated further through the growth of grey fur covering his entire body and the enhancement of all of his existing abilities, especially his strength, and Hank also gained a nearly instantaneous healing factor. The psychological impact of this first transformation caused Beast to experience short-term amnesia and also made it difficult for him to control his animalistic instincts, which would cause him to slip into an uncontrollable berserker rage during combat. However, his body suddenly mutated again after a short time, changing his fur color from grey to black (although comic book printing technology depicted it as blue), returning his strength to previous levels, and losing his healing factor. He was also able to more easily control his animal instincts after this second mutation. Beast gained the ability to emit mood-altering pheromones, causing sexual attraction in women. Hank McCoy briefly returned to his human form with his hair color now being depicted as black, not reddish brown. During this time he was occasionally depicted with claws and fangs, but these were not a part of his original mutation. However, as a result of being touched by Pestilence his strength began to increase exponentially while his intellect began to decrease.
After Infectia's kiss restored Hank to his simian physique, his intellect had stabilized and returned to his previous genius-level, and his strength had increased to superhuman proportions. Beast's fangs and claws became a consistent part of his appearance after this return to his "blue and furry" form.
Beast would later be stabilized to a more human/ape-like form with pointy ears, fangs, and no hair except for the fur on his head.
After being critically wounded, Hank's body undergoes a secondary mutation, jump-started by Sage. The result is a more feline appearance equivalent to that of a big cat with a cat-like head and feet. His strength, speed, stamina, sturdiness, and senses increase further with this change. He gains catlike agility, flexibility, coordination, and balance, and all his senses are enhanced to twenty times that of a normal human being. In addition, Beast develops an accelerated healing factor that allows him to repair mild to moderate injuries within the span of a few hours. However, as his hands and feet change from simian to feline (going from a normal human set of four fingers to just three, retaining the opposable thumb), he loses his superhuman dexterity, once admitting that he used to play the guitar, but is now learning to play the drums instead. Following the X-Men's relocation to San Francisco, Beast discovers that he had regained some of his old manual dexterity. In the first issue of Warren Ellis' Astonishing X-Men run, Beast also comments he no longer needs full sleep.
It is later discovered that his secondary feline mutation is still detrimental to his health: as such, with the combined efforts of past versions of Jean Grey and himself, Beast's condition was stabilized in a more human/ape-like form, possessing blue fur and larger than the average human male but otherwise fairly human.
Hank possesses a brilliant intellect. He is a world-renowned biochemist, having earned PhDs in Biophysics and Genetics, and is the man who cured the Legacy Virus. He frequently functions as both field medic and in-house physician for the X-Men, despite not technically having a medical degree. His intelligence and expertise in genetics rival that of Professor X, Moira MacTaggert, and Kavita Rao. Despite this, he has never received a Nobel Prize or been elected to the United States National Academy of Sciences. A Renaissance man, McCoy is well versed in many fields including linguistics (fluent in English, German, French, Latin, Spanish, Japanese, Arabic, and Russian as well as the fictional language Latverian), literature, philosophy, psychology, sociology, history, art and art history, anthropology, music, political science and economics with a special affinity for science and technology and a penchant for quoting literary classics including Shakespeare's plays. His vast scientific knowledge ranges from theoretical physics, quantum mechanics, differential equations, nanotechnology, anatomy, biomedicine, analytical chemistry, electrical engineering, and mechanical engineering to the construction of a hyper-magnetic device. An electronics expert, he often repairs Cerebro and makes upgrades to the Danger Room settings. He has made several deus ex machina devices on par with Reed Richards, including a device that strips entities of cosmic powers. While not a medical doctor, he was able to perform brain surgery on the Red Skull to extract the fragment of Charles Xavier's brain that the Skull had grafted onto himself, removing the Skull's telepathic abilities while leaving the villain otherwise apparently healthy.
After a meeting with Doctor Strange, the displaced younger Beast has mastered a combination of science and magic, allowing him to return himself and his four teammates to the past for a few minutes, although he notes that it took a great deal of effort to send them back for that long and it merely confirmed that history has been 'reset' so that the displaced X-Men are no longer 'needed' in the past. He has also mastered a mystical portal that allowed him to send the Juggernaut to Siberia after passing through Hell.
According to writer Will Murray, a possible inspiration for the Beast was Andrew Blodgett "Monk" Mayfair, a companion of pulp hero Doc Savage. Both are possessed of an apelike appearance and are brilliant scientists. Before becoming more erudite in later issues, McCoy also used a great deal of slang in his early appearances much like Monk.
The younger Hank and All-New X-Men defect to Cyclops's school, after the events of the Battle of the Atom unfold. Young Hank is later transported to the Ultimate Marvel universe, where he is captured by that world's version of Doctor Doom, then teams up with the Guardians of the Galaxy in finding the Black Vortex.
The time-displaced Jean Grey accidentally reads the mind of the present Beast and finds out that he regrets never telling her his true feeling. Jean then confronts the time-displaced Hank and gives him a kiss. They do not have time to develop their relationship since Dr. Octopus attacks them in New York City,
Following the reconstruction of reality after the Battleworld crisis, the displaced X-Men remain in the future, travelling the world as they try to find their place, while the 'present' Beast works with the Inhumans to find a means of resolving the recent release of Terrigenesis crystals that have proven dangerous to mutants. Increasingly frustrated with his inability to find a way back to their time through science, the young Beast contacts Doctor Strange for advice on using magic, but although Strange cannot help due to his currently weakened powers, when Hank is able to help him find a solution to a dimensional rift he was investigating, Strange reassures Hank that he is smart enough to find a solution to the current dilemma. After the conflict with the Inhumans is concluded, the younger Beast reveals to his teammates that he has determined, through a combination of science and magic, that the younger X-Men cannot return to the past as they are already there, leaving them free to travel the world and find their own place.
The young Beast finds himself working alongside Magneto along with the rest of the time-displaced X-Men doing whatever it takes to preserve Xavier's dream. Beast begins to use magic more freely on their missions, something that greatly distresses Cyclops. Whenever they are at X-Men HQ Beast spends most of his time on his own to continue study magic and becomes increasingly reclusive in the process.
In Marvel 1602, Beast is known as Hal McCoy and retains his original appearance of a human with lengthy arms and legs and enormous hands and feet. He is well spoken and eloquent, and a member of Carlos Javier's (Professor X) group of "witchbreeds", though he tends to not give others a chance to speak when he is talking. When several soldiers stare at him, he glowers and attributes his appearance to his origin as an Orkneyman. He also tells of his mother's humiliation when he was born, her cruel neighbours having suggested that Hal's father was an ape.
He reappears in Spider-Man 1602. Between the two appearances he was working with Henri Le Pym, a natural philosopher employed by Baron Octavius to create a potion that will counteract the effects an octopus based serum have had on his physiology. Testing some of the potions on himself, Hal becomes more bestial in appearance. When he first appears in Spider-Man 1602 #1, he is imprisoned in Le Pym's laboratory, treated as a source of mutagenic blood rather than a fellow scientist.
He is not shown clearly until he is released from the cage by Peter Parquagh in #3. He resembles a gorilla to a greater extent than the main universe Beast, with only a slight blue tinge to his fur.

He was seemingly killed while fighting MODOK, but was in fact taken to join the Exiles. It was revealed that this version of Beast lost most of his intelligence due to his mutation, however he regained his mind after he was briefly connected to the Crystal Palace. Also this version of Beast was in a romantic relationship with Wonder-Man. At the end if the series, Beast was given the option to return to his home, but seeing that Wonder-Man was killed in battle shortly after, decided he had nothing to go back to and remained with the team.
During the "X-Men: Endangered Species" storyline after House of M, Beast tried to ask Doctor Strange for help fixing the problem. Dr. Strange not only demonstrated that he could not help, but showed Beast a number of alternative reality versions of him who were facing equal failure, including but not limited to: a version of Beast in the raiment of a Catholic hierarch, a red-furred gun-toting version seeking a cure with Bishop, a version with a cyborg arm, a wheelchair-using version using a synthesis of magic and technology, a version who looked like Beast's original human form, and a caped Beast in a snowy landscape.
In the Here Comes Tomorrow story arc (set 150 years in the X-Men's future), Beast takes on the role of Headmaster of the Xavier Institute after the death of Jean Grey and the retirement of Charles Xavier and Scott Summers. Unable to cope with the pressures of this position and trying to find a cure for the looming extinction of the human race, Beast turns to the power-enhancing drug Kick. Unbeknownst to him, Kick is an aerosol form of an entity known as Sublime. Sublime takes over Beast's body, relegating him to a passenger in his own form. 150 years after the death of Jean Grey, Sublime is finally purged from the aged, white-furred Beast, who is seconds later beheaded by Sublime's champion Appolyon.
In the House of M reality, Beast appears as a scientist working alongside Hank Pym and Forge, all of whom work for Tony Stark. Here, he retains his human appearance similar to when he first joined X-Men and Beast assumes he is superior to humans, simply because of his mutations.

In X-Men: Misfits, Beast is portrayed as always in a blue bear humanoid like form with a short tail, he wears glasses and a tie with the X-Men symbol on it. He is a professor at the school, and is strangely never referred to as Hank or Beast by name in the story.
In the Mutant X universe, Hank McCoy is a member of the Six, a team of mutant heroes led by Havok. Instead of a furry simian-like form, McCoy's experiments mutated him into a green, amphibious form with childlike intelligence, codenamed the Brute. As well as having his usual acrobatic and athletic ability, Hank has webbed extremities and can breathe underwater. He becomes further mutated during the Inferno crisis, when he makes a deal with the demons S'ym and N'astirh. This mutation gives him hooves instead of feet.
When the Goblyn Queen first ascends to power, she brainwashes the Brute into serving her purpose. Scotty Summers, the child of Havok and the Goblyn Queen, unknowingly frees the Brute from her control. After the Goblyn Queen is defeated, the Brute chooses to remain with the Six.
Later, Brute jumps in front of a psychic blast from Professor X that was meant for Havok. This has the unexpected effect of restoring his intellect, and the Brute tries to find a way to return Havok to his reality, to cure Bloodstorm and Gambit of their vampirism, and to restore Ice-Man. Brute succeeds in all, but Havok opts not to return to the main Marvel Universe. The Brute's intelligence is lost again as the after-effects of Xavier's blast wear off.

He was later killed by Sage.
One notable crossover in which Beast appeared was the Star Trek/X-Men crossover, in which the X-Men traveled to the 23rd Century to team up with the original crew of the U.S.S. Enterprise. During the encounter, Beast met his Star Trek counterpart, Dr. Leonard McCoy. (When a nurse calls out, "Dr. McCoy!" both Beast and Dr. Leonard McCoy answer, "What?") The story also featured Beast teaming up with Mr. Spock to stop an inter-dimensional rift caused by the villain Proteus. In a one-page drawing included at the end of the issue in the artist pin-up gallery, we see Beast and Mr. Spock engaged in a game of 3D chess, with Beast intently studying the chessboard while perched on the headrest of a chair.
In the Ultimate X-Men, Ultimate Henry "Hank" McCoy was born with hands instead of feet, he tried to make a substance that would cure his mutation but instead it only made it worse. With his own parents denouncing him throughout his childhood for his genetic status, he chooses to hide his immense intelligence to avoid further complications. Hank becomes a founding member of the Ultimate X-Men taking the codename Beast. He also takes on the role of the team's elite engineer, frequently upgrading the X-Men's Blackbird X-Jet and Danger Room sequences.
When the team is kidnapped by Weapon X, they operate on him, causing him to take on his blue furry appearance and gain additional, strengthened senses, such as smell and hearing.
Beast begins an on again/off again relationship with Storm. Storm loves him because of his intelligence, but Beast's inferiority complex often gets in the way of their relationship. He becomes convinced that Storm only loves him because Professor X is using mind control on her. Beast starts an online relationship that eventually leads to the Ultimate War debacle, when he lets it slip that Magneto is still alive (the supposed mutant "supermodel" Naomi he is chatting with is actually the Blob fishing for information).
Beast is killed after being crushed under the rubble of a Sentinel attack. While his death is felt by all of the X-Men, it has had the greatest impact upon Storm. However, it is revealed that the Beast is revived at the hospital. Xavier and Nick Fury keep his survival a secret, Xavier making Beast believe he is regularly visiting his family and the X-Men to keep him occupied. Having reversed himself back to his normal human appearance (maintaining the blue hair from his former kangaroo kidney transplant, which was independent of Weapon X's modifications), Hank is now working on a cure to a "Legacy Virus", created by an anti-mutant government conspiracy led by Admiral Stryker, that threatens mutants. The apparent death of Xavier (actually time travel) breaks the mental holds on him so he knows that everyone thinks he is dead and is not happy being forced to work for S.H.I.E.L.D. Beast escapes S.H.I.E.L.D. custody and heads towards Xavier's Institute. He later rescues Pyro, and shocks his former teammates by revealing that he is still alive. After being proved to be the real Beast by Psylocke and Wolverine, he is allowed to join Bishop's new X-Men and continues his relationship with Storm. After Bishop's death, Xavier is revealed to be alive and Beast returns to his life at the Xavier Institute.
In Issue #1 of Ultimatum, Beast, among Dazzler, Angel and Nightcrawler are overwhelmed in Magneto's flooding of New York (via Thor's hammer). Angel survives the flood and recovers the bodies of Dazzler and Beast, who drowned. As Scott mourns over his dead friend's corpse, he sorrowfully comments that he honestly cannot believe that "that size 16-wearing dweeb" would borrow his best tie and then die with it on.
Hank has a genius level IQ. His mutation grants him a simian physiology with superhuman strength, speed, stamina, reflexes, agility, flexibility, coordination, balance, and manual and pedal dexterity so great he can write with all his hands and feet at once and tie knots equally well with both his fingers and toes. The Weapon X program mutates Hank further, causing him to evolve into a more animalistic form with claws, fangs, pointed ears, enhanced senses, and thick, blue fur covering his entire body. Since then, he is like this continuously throughout the comics until his own modifications are made.
An issue of What If? asked "What If Beast Had Truly Become a Beast." As Hank McCoy has isolated a catalyst for a mutation in a hormone extract, industrial spies attacked and he drank the extract. He then turned into a beast when the catalyst was too well concentrated. As he escaped into the night looking for meat, Professor X telepathically contacted Beast to ask if he was OK. Beast savagely responded that he was no longer an X-Man and refused to accept his help. Professor X sent the X-Men to retrieve him before any harm can come to people. Beast managed to take Angel down before being scared away by Jean's telepathic scream. When Jean Grey and Cyclops caught up with him, Beast attacked, throwing rocks at them. With his optic beam, Cyclops destroyed most of the stones but one is able to knock out Jean Grey. When Beast was about to claim Jean as a meal, Professor X used his telepathy to calm Beast down. In his final human words, Beast told Professor X not to let him become an animal. To keep humans safe from him, the X-Men released Beast into the Savage Land where he became Ka-Zar and Zabu's hunting companion.
Beast appears in the What If? story "What If the X-Men Died on their First Mission?" as the leader of a newly formed X-Men team following his former teammates' demise on Krakoa, consisting of Theresa Cassidy (who named herself Banshee in honor of her late father), Rahne Sinclair, Namorita, and James Proudstar, the brother of the original Thunderbird.
Beast appears as the monkey, Aoi (Japanese for blue). Aoi appears younger and more monkey-like than the 616 version of Beast, although he retains his blue fur. Unlike the studious and intellectual Beast, Aoi is playful and mischievous. After being outwitted, Aoi joins Hitome (Cyclops). He also shows an ability to change into a larger stronger form.
In this alternative reality of X-Men: Forever (with a history identical to 616) that begins after Chris Claremont's X-Men 1–3, Beast retains his blue-furred ape-like appearance, and is the X-Men's chief-scientist. Beast is responsible for checking for blood-work of two Storms (one who is an evil adult and the other who is a teenager) and discovers that they are identical. After the death of Logan, who Jean was having an affair with behind Cyclops' back, Beast becomes Jean's closest friend and confidant, trying to help her over-come her loss, and her newly re-awakened Phoenix power. Recently, Jean has admitted to knowing about Hank's long-time crush on her, and the two begin a relationship.

In the possible future witnessed in Battle of the Atom, Beast has mutated further, with one side of his head notably more feral than the other, including a horn. He has also defected to the Brotherhood, having apparently become disillusioned with the X-Men's goal while blaming himself for causing some unspecified catastrophe by bringing his past self into the present. He is apparently killed in the final confrontation between the various time-displaced X-Men teams, with the past and present Hank vowing that they will never accept that they become what they have just witnessed. However, he later appears alive during the future Brotherhood's new attack on Cyclops' base, during which the X-Men discover that the entire Brotherhood (With the exception of Raze, the son of Wolverine and Mystique) were under the control of Charles Xavier II (The apparent son of Xavier and Mystique), with Hank's future self being allowed just enough freedom to be horrified at what Xavier II was making him do as the telepath blames the X-Men for failing to live up to Charles Xavier's dream. At the conclusion of the fight, Hank and others are freed from Xavier II's control and allowed to return to their home time, with Hank still blaming himself for some past mistake but committed to making up for it by returning to the X-Men.
