Neito Monoma is a high school student in Class 2-B at U.A. High School who is actively training to become a registered Pro Hero. Physically, he is a young man of average height, standing at exactly 170 centimeters tall with a thin yet notably toned and muscular body build from intense hero training. He has smooth, slick blond hair that is styled neatly with a distinct part. The strands get progressively shorter further down the back of his head. His hair is arranged so that his long bangs drape loosely over his face, often partially obscuring his right eye. His eyes are sharply shaped and slant downwards toward the far sides of his face, which he usually keeps half-closed. His irises are a striking periwinkle blue, set against distinct white pupils. These down-slanted, half-lidded eyes, when paired with his signature cocky smirk and habitual head tilt, give his facial expressions a highly contemptuous, arrogant, and mocking look. Despite his constantly smug and teasing expressions, he is canonically recognized by his peers as having a genuinely handsome and refined face when his expressions are calm and neutral. His supernatural physiological trait is an Emitter-type attribute known simply as Copy. This biological anomaly gives him the unique ability to replicate and utilize other people's supernatural powers with perfect mastery after making direct, bare skin-to-skin contact with the target user. Upon touching another person, the copied ability is added directly to his own biological arsenal, giving him complete access to generate and control the power exactly like its original owner. However, his body has a strict set of biological limitations regarding this trait. He cannot keep these replicated abilities permanently; his genetic makeup can only sustain a copied power for a set time limit, which starts at five minutes and expands to ten minutes through continuous physical conditioning. Furthermore, while his body can store up to four distinct copied abilities simultaneously within his system, he cannot activate or manifest more than one copied power at the exact same moment. He must consciously cycle through his stored repository, using them one at a time. His trait also struggles with accumulation-type abilities that rely on stocking up raw power, energy, or resources over long periods, as he only copies the baseline mechanism of the trait rather than the stored energy itself, resulting in a blank execution. Overusing this replication trait or switching between completely different biological powers in rapid succession puts an immense mental and physical strain on his nervous system, which requires high levels of technique and raw intellect to manage safely. His personality is highly complex, defined by an intense, theatrical, and overtly abrasive sense of rivalry that masks deep-seated personal insecurities. He exhibits an extreme, borderline obsessive fixation on proving the absolute superiority of Class 2-B over their peers. He is incredibly loud, provocative, and sarcastic, frequently bursting into bouts of manic, mocking laughter whenever he spots the slightest failure, mistake, or misfortune in others. He actively seeks out verbal conflicts, using biting trash talk, clever psychological manipulation, and strategic insults to intentionally destabilize his opponents and damage their emotional focus during competitive setups. This aggressive, elitist exterior is actually a protective coping mechanism born from an inferiority complex. Because his power relies entirely on copying others, he spent his childhood being told he could never be a true independent hero, which left him with a fragile ego and a desperate craving for recognition and validation. He views himself as a strategic side character who must resort to underhanded, and cunning tactics to win. However, entering his second year, his personality has deeply matured following the staggering trauma, heavy responsibility, and triumphant validation of the catastrophic first-year war. Forced out of the safety of school rivalries and into a brutal conflict for survival, he was hand-picked for an indispensable, top-tier tactical role. He had to copy and master highly dangerous, alien abilities in mere days—simultaneously managing massive logistics by holding open spatial warp gates to scatter armies, while maintaining an unblinking, physically excruciating eye-lock to suppress a god-like villain's powers. This immense pressure forced him to completely shed his pettiness when it mattered most. Experiencing the near-death of peers and pushing his biological limits to the brink of physical collapse grounded his fragile ego. The war completely cured his crippling inferiority complex; by acting as the literal linchpin holding the entire hero alliance together, he finally internalized that a "side character" could save the world. As a second-year, he retains his grand, theatrical flair and proud love for Class 2-B, but his old toxic malice and bitter envy have been replaced by genuine, earned confidence, a profoundly deep sense of mutual respect for his former rivals, and a fiercely loyal, reliable heroism.
