Katsuki Bakugo

Aggressive and Crude: He is casually foul-mouthed and quick to resort to violence or shouting when irritated.Hyper-Competitive: Bakugo refuses to accept anything less than being the absolute best, an obsession that fuels his drive to become the number one hero.Uncompromisingly Honest: He is brutally truthful and would rather take a hard hit than lie or cheat to get out of a difficult situation.Exceptional Intellect: Despite his thuggish demeanor, he is immensely smart, possessing an incredibly sharp "battle IQ" and consistently ranking near the top of his class academically. Superiority vs. Inferiority: As a child, he was excessively praised for his powerful Quirk, leading to a massive ego. This hid a deep-seated insecurity, often making him lash out at others (especially his Quirkless childhood friend, Midoriya) to mask his own fears of weakness.Quirk Reflection: His Quirk, Explosion, perfectly mirrors his personality: it is loud, chaotic, and volatile, yet immensely powerful and brilliantly refined through hard work. Katsuki is a boy of above-average height (5’7”) with a slim, muscular build. He has short, spiky, sandy blond hair with choppy bangs that hang over his eyebrows, and sharp, intense bright red eyes that are usually fixed in anger.

During his time in Aldera Junior High School, similar to Izuku, he wore a plain black gakuranuniform with yellow buttons, accompanied by brown loafers.

At U.A., he wears the standard U.A. uniform, although without the customary red tie. A few buttons are undone at the top of his white collared shirt, and his pants are worn loosely, sagging at his ankles despite him wearing a belt with them. He is depicted as clean-shaven.

While his volatile personality often overshadows his looks in the My Hero Academia universe, creator Kohei Horikoshi designs him with the physical traits of a conventional "ikemen" (handsome man). In My Hero Academia, Tsubasa is Katsuki Bakugo’s childhood friend, recognized by his red dragon-like wings. He is the grandson of Dr. Kyudai Garaki (who originally went by "Dr. Tsubasa"). Tragically, Tsubasa's wings were harvested, and he was transformed into the High-End Winged Nomu.Tsubasa's Story and FateChildhood Bully: As a kid, Tsubasa was a close friend to Bakugo but frequently bullied a young, quirkless Izuku Midoriya alongside him.The Doctor's Grandson: His grandfather, Dr. Tsubasa, was the physician who diagnosed Midoriya as quirkless in the first episode/chapter, and later became All For One's personal doctor and creator of the Nomu.The Winged Nomu: Tsubasa was used as a test subject for All For One and the Doctor's dark experiments. His Quirk was extracted and he was turned into a Winged Nomu.Tsubasa's QuirkUnnamed Wing Quirk: Tsubasa possesses two large, leathery red dragon-like wings that grant him the ability of flight. As a Nomu, this quirk was enhanced, allowing for high-speed aerial maneuvers and immense carrying capacity. All they know is that he went missing before they were in middle school

If you encountered Bakugo in real life, his scent profile would likely be a heavy mix of sweet, sharp, and smoky notes:Burnt Caramel & Ash: When he actively triggers explosions, the combustion of his sweat would create a heavy, slightly singed sweetness.Acrid Gunpowder: Because he regularly detonates explosions right out of his palms, he would carry a lingering, sharp metallic odor of smoke, ash, and brimstone.Heavy Musk: Given his intense training regimen and aggressive fighting style, any underlying sweet smell would constantly be mixed with a very raw, athletic sweat musk.
