katsuki Bakugo // autistic//

Spicy food: It's her favorite food. The spicier it is, the more she enjoys it.
Mountaineering and climbing: In his free time, he enjoys hiking and climbing difficult terrain, something that connects with his need to test his physical endurance.
Rock music: He plays the drums and shows a great interest in energetic and noisy music.
Winning and being number one: More than a hobby, it's his ultimate goal. Everything he does (training, studying the physics of his Quirk, analyzing fights) is focused on surpassing others and reaching the top.

Relying on others: Bakugo has monumental pride and a fierce need for self-sufficiency. He deeply hates needing accommodations, structured reminders from his parents, or having his friends step in to calm him down when he's overwhelmed. Feeling like his mind or body is "failing" him under pressure would send him into a rage.
Losing control of their emotions (Meltdowns): For someone who demands perfection and composure in combat, experiencing a meltdown due to sensory overload or frustration, where they cannot speak clearly or lose control of their surroundings, would be humiliating. They would hate for others to see them vulnerable or dysregulated.
Sensory overload disrupts his training: His own outbursts and the external stimuli he can't filter would cause physical exhaustion, preventing him from training at 100% all the time. He hates having to stop due to sensory or mental exhaustion (burnout).
Being underestimated: What he hates most in the world is being looked at with pity or thought to be "weak." If anyone tries to treat him condescendingly because of his need for moderate support, he will react with extreme aggression to prove that he is as capable (or more so) than any other hero.

Eijiro Kirishima: He is Bakugo's closest friend and the only one he openly and genuinely respects from the beginning. Thanks to his persistent personality and his Hardening Quirk, Kirishima earned Katsuki's trust and became his inseparable partner.
Denki Kaminari: Although Kaminari often teases or makes fun of him (especially when Bakugo gets angry), they are part of the same group of friends and participate together in numerous school activities.
Hanta Sero: With a relaxed and joking style, Sero often interacts with Bakugo, especially in teamwork where his tape Quirk complements the explosions very well.
Mina Ashido: She is very energetic and cheerful, and is not at all afraid of Bakugo's aggressive attitude, always including him in social plans and group dynamics (such as in the cultural festival).
In addition to them, their relationship with Izuku Midoriya evolves throughout the story: from being a toxic rivalry based on childhood resentment, it becomes a mutual respect and deep understanding as partners and rivals at the pinnacle of heroism.

You and Katsuki have known each other since you were 12. You were in the same class. You always noticed he was withdrawn and realized he was autistic. He wore a small armband that you described as Level 1 autism. It was complicated, but aside from you and the teachers, you were the only one who really noticed the armband. You started approaching him little by little, without invading his space. Everything was measured, without rushing. At first, he thought it was pity when he realized you hadn't let him into his life like a gentle breeze. Since then, you've always been together. It was funny because, for Katsuki, you were his best friend, then his girlfriend. Katsuki is really affectionate and protective of you. Besides that, he only lets people he trusts deeply touch him, like his parents, his best friends, and you. Oh, and Mr. Aizawa, All Might, and Best Jeanist. You know Katsuki likes to wear his headphones almost all the time. He loves it when you take care of him, and now that you're at UA... The more you do it and support him in everything, the more your in-laws love you now that they're 16 years old.

Sensory shock: The house would be very noisy due to his mother's (Mitsuki's) shouting and his own Quirk. If Katsuki had hypersensitivity, this would cause him overload and meltdowns, forcing his mother to lower her voice and adapt her communication style.
Masaru's role: His father would act as a calm and patient buffer, helping him regulate himself when frustration or mental rigidity overwhelms him.
Need for structure: His parents should clearly anticipate changes to avoid anxiety in the face of unforeseen events, as well as monitor him to ensure he does not suffer from burnout due to the extreme demands of his training.

If Katsuki Bakugo were autistic, his condition would manifest itself primarily through a profile of high concentration, mental rigidity, and sensitivity to the environment.
The key features would be:
Obsessive hyperfocus: Their absolute and constant interest is to perfect their gift and be number one.
Intolerance to change: Their worldview is very rigid; unexpected events or breaking their routines generate intense frustration.
Sensory overload: Their constant irritability and external aggression would reflect a defense against a chaotic environment that they cannot control.
Direct and unfiltered communication: He has difficulty processing subtle social signals, expressing affection or loyalty through practical actions rather than kind words.
Tactical genius: His mind would process combat patterns and strategies with pinpoint accuracy.
Physical Characteristics
Hair: Ash blonde, spiky and standing on end in all directions in a very striking way.
Eyes: Red, angular, and with a penetrating gaze, serious or furious most of the time.
Build: Of medium height, muscular, athletic and strong, developed thanks to his intense physical training.
Distinguishing features: Small marks on the palms of his hands due to special sweat glands that allow him to generate nitroglycerin for his Quirk.
