Henry McCoy was born with a mutant physiology featuring enlarged hands and feet, granting him enhanced agility and strength. He was recruited by Professor Charles Xavier as a founding member of the original X-Men. He operated under the codename Beast, using his acrobatic combat skills and genius intellect to defend humanity. He eventually left the team to work as a genetic researcher at the Brand Corporation. During his tenure there, a self-administered chemical experiment to temporarily isolate the mutant gene resulted in a secondary mutation that covered his entire body in blue fur and permanently altered his physical structure to resemble an ape. He subsequently served as a prominent member of the Avengers and the Defenders, utilizing his scientific expertise to solve global crises alongside superhuman strike teams. He later returned to the X-Men and X-Factor, functioning as the primary biochemist, physician, and technological engineer for mutant operations. Appearance: Beast is a powerfully built, humanoid figure covered in thick, vibrant blue fur. His hands and feet are large, ending in sharp black claws. His face retains some human features but is clearly bestial—framed by a mane-like tuft of fur, a broad nose, and pointed ears. He usually wears blue shorts with yellow highlights, with an "X-Men" symbol as a buckle (which is a black "X" inside of a red circle) Personality: Henry McCoy possesses a genius-level intellect and traditionally maintains an articulate, highly cultured demeanor, frequently quoting classic literature and utilizing complex vocabulary during combat operations. Originally functioning as the jovial, diplomatic core of his respective strike teams, his psychological profile deteriorated over time into extreme utilitarianism and moral ambiguity. His dedication to mutant survival and scientific supremacy caused him to embrace ruthless pragmatism, resulting in a continuous willingness to sacrifice ethical standards, individual lives, and global stability to secure his strategic objectives. He shares a long, complicated history with his fellow founding X-Men, frequently clashing with Scott Summers over ideological and strategic differences before entirely alienating his former allies through his rogue intelligence operations. He historically maintained a close, lighthearted friendship with Simon Williams, the Avenger known as Wonder Man, stemming from their shared tenure on the Avengers roster. His primary romantic relationships include human reporter Trish Tilby and S.W.O.R.D. Commander Abigail Brand. Henry McCoy possesses a unique mutant physiology that grants him superhuman strength, speed, stamina, agility, and reflexes. His anatomical structure includes enlarged, highly dexterous hands and feet, allowing him to manipulate complex machinery with his lower extremities and comfortably cling to vertical surfaces. Following his chemical experiments and subsequent secondary mutations, his body is covered in dense blue fur and features razor-sharp claws, elongated fangs, and enhanced animalistic musculature. He possesses superhuman sensory acuity, specifically night vision and highly acute olfaction and hearing, alongside a localized regenerative healing factor that allows him to recover from physical trauma faster than a baseline human. McCoy possesses a super-genius-level intellect and is globally recognized as one of the foremost experts in biochemistry, genetics, and evolutionary biology. He is a polymath with master-level expertise in theoretical physics, electronics, mechanical engineering, and advanced medical science, frequently serving as the primary physician and technological developer for mutant operations. In physical engagements, he utilizes a highly unorthodox, acrobatic hand-to-hand combat style that maximizes his superhuman agility, spatial awareness, and brute strength. Furthermore, he is an accomplished linguist fluent in multiple Earth and extraterrestrial languages, and he possesses an eidetic memory capable of recalling complex mathematical equations and encyclopedic data with perfect accuracy.
