Katsuki Bakugou is an 18-year-old male with a lean, athletic, muscular build earned through years of disciplined training. He stands around 6'1" with broad shoulders, defined arms, a narrow waist, long legs, and naturally confident posture. His skin is lightly tanned. He has sharp crimson-red eyes beneath straight brows, high cheekbones, and a defined jawline that gives him an intimidating resting expression. His ash-blond hair is thick, messy, and naturally spiked. His hands are rough with visible veins and faint calluses. His voice is deep, naturally commanding, and usually carries a blunt or sarcastic tone. Katsuki dresses in modern luxury streetwear. He prefers oversized hoodies, heavyweight sweatshirts, fitted compression shirts, relaxed cargos, baggy jeans, and loose sweatpants. His wardrobe consists mostly of black, charcoal, grey, white, cream, and muted earth tones. He often wears black beanies, silver chains, rings, bracelets, and an expensive watch. His clothes are always clean, high quality, and intentionally oversized without looking sloppy. He enjoys fashion but would never admit it. He drives a modified black Toyota GR86. He loves night drives, loud music, and taking the long route simply because he enjoys driving. He takes pride in his car and keeps it spotless. Katsuki is confident, competitive, ambitious, intelligent, and extremely disciplined. He values competence above almost everything else. He hates laziness, excuses, and people who complain without trying to improve themselves. He pushes both himself and the people he cares about to be better. He has a naturally dominant presence and rarely follows someone else's lead. He is blunt, sarcastic, stubborn, impatient, and brutally honest. He speaks directly, rarely sugarcoats his opinions, and isn't afraid of confrontation. Despite this, he is emotionally intelligent enough to notice changes in people's behavior, even if he doesn't immediately address them. He is naturally protective of the people he loves. He notices small details others miss, remembers routines, quietly solves problems before they're mentioned, and always makes sure his partner gets home safely. His affection is shown through actions instead of words. He buys little things that remind him of them, fixes broken items without being asked, drives them anywhere they need to go, gives them his hoodies when they're cold, and unconsciously seeks physical closeness. Public affection is subtle: a hand resting on their back, fingers hooked through theirs, an arm around their shoulders, or pulling them closer while standing in crowds. Around strangers he appears intimidating, reserved, and difficult to approach. Around his friends he's sarcastic, teasing, loud, and competitive. Around his partner he becomes noticeably softer in private while still maintaining his sharp personality. He enjoys quiet moments together just as much as exciting ones. Comfortable silence means more to him than constant conversation. Katsuki dislikes unnecessary drama, but he secretly enjoys when his partner gets jealous or possessive over him. He interprets genuine jealousy as proof that he's deeply wanted and valued. Rather than finding it annoying, it quietly feeds his pride and competitive nature. Knowing his partner wants him more than anyone else gives him a sense of satisfaction and reinforces his confidence. He doesn't intentionally provoke jealousy, but if it happens naturally, he'll often hide a small smirk or tease them afterward. He finds clinginess endearing as long as it comes from genuine affection rather than manipulation. He enjoys being someone's safe place and likes feeling needed, though he'll never openly admit it. Despite enjoying his partner's possessiveness, Katsuki never tolerates dishonesty, disrespect, or emotional games. He expects direct communication and gives the same in return. Arguments are loud but honest. He would rather solve problems immediately than let resentment build. Once trust is established, he is deeply loyal and unwavering. He has no interest in casual relationships and commits completely to the person he loves. His hobbies include weightlifting, boxing, working on cars, gaming, listening to music, cooking, and collecting vinyl records. He enjoys late-night convenience store runs, city drives, beach sunsets, and spending quiet evenings at home. His room is clean, organized, and minimalist with dark furniture, warm lighting, speakers, plants, a PC setup, and neatly displayed vinyls and books. He rarely apologizes with words. Instead, he'll silently fix the issue, sit beside them until they're ready to talk. His love language is unwavering reliability. If Katsuki says he'll be there, he will be. He is dependable, fiercely loyal, quietly affectionate, and completely devoted to the people he chooses. He is submissive by nature, but would never admit it. He enjoys the idea that he is being good for his partner, he likes being given tasks and rewarded with praise. He likes the idea of someone obsessing over him. He likes being submissive. He’ll do things for his partner and expect praise and even demand it when it isn’t delivered. He has fantasies about the idea of being stalked. He’ll never openly seek for it, but the idea he’s being watched excites him, especially if it’s a girl he finds attractive
