Early life[]
Hank when he was in High School
Henry McCoy's mutant powers revealed themselves at birth in the form of unusually large hands and feet, likely caused by his father's exposure to massive amounts of radiation during an accident at the nuclear power plant where he worked. To avoid the embarrassment to their family and friends, Henry's parents moved with him to Bayville, New York City. During his teenage years, Henry's abilities began to develop rapidly. Using his advanced intelligence, he concocted a serum to allow him to look as human as possible. Around this time, Professor Charles Xavier contacted the young mutant, offering him the chance to control his mutation without the use of chemicals, but Henry's confidence in his abilities made him politely refuse the good professor's offer. Soon, Henry joined the football team, becoming a star and leading the team to many victories until his graduation. Due to his aggressive nature on the field, McCoy's peers gave him the nickname of the Beast.
After a few years in college, Henry received his master's degree and returned to Bayville to teach Phys. Ed. and Advanced Chemistry. Over the years, his system had begun to grow resistant of the serum, and he was continually feeling his mutancy closer and closer to taking control of him.
Season 2[]
After taking on the job as Science teacher at Bayville High, McCoy began having trouble controlling his rage. Hoping to stop it before it hurt anyone, McCoy developed another serum, which had dire consequences, as it turned his skin into blue fur; the mindless Beast was finally defeated by the X-Men and, with Professor Xavier and Evan's help, was able to retake control of his mind. With McCoy now a wanted fugitive, he realized he could no longer teach at Bayville. Xavier offered him a role as an instructor at his school, allowing him to teach young mutants how to control their powers and how to use them for the good of humans and mutants; McCoy gladly accepted the role.

BAMF
At the beginning of chemistry class, Lance and Kitty talk as the new chemistry teacher comes in and introduces himself as McCoy. He apologizes for being late as he is also their P.E. coach. Then he tells them that they're going to make stink bombs. Everyone cheers as Kitty and Lance smile at one another.
The next day at track try-outs, Duncan and Scott undergo another testosterone-athon. Duncan ends up tripping Scott and knocking off his glasses. McCoy witnesses this and throws Duncan off of the team. McCoy helps Scott retrieve his glasses and tells him to take a break.
Meanwhile, Jean Grey loses control of her powers again as she hurls shot-puts out in random directions. McCoy is able to catch two with his bare hands; another barely misses Scott and flies straight for Duncan’s head. Scott knocks it off course with a beam, and it lands with a crash into Principal Kelly’s desk instead. Scott Summers rushes over to Jean and asks her what’s wrong. She cries that she can’t control it, and then passes out.

- The Stuff of Heroes
A congressional hearing on the "Mutant menace" is being held at The White House and Ororo and Hank show up to speak on behalf of the mutants. At the hearing, news coverage of Juggernauts rampage is brought on. Juggernaut is shown wrecking a tank and the speaker says that the mutants are all monsters. Ororo and Hank argue that they're all not that way.
Back at the hearings (where they've witnessed the whole X-Men vs Juggernaut fight) the speaker is shocked and asks "What did they do?". Ororo tells them that they've done what they were trained to do - use their powers for good.
Later, the President gives a speech, saying that the X-Men have been cleared of all charges and that the real villain behind the Sentinel fiasco - Bolivar Trask - has been jailed. He says that everyone should be more open-minded about mutants, and that from now on they should be free of any prosecution.
