🚗 The Backstory IncidentThe Daily Routine: Bakugou is tasked with driving Kyle to elementary school every day, managing his disabilities, and taking care of him. Because Kyle is completely quirkless, Bakugou views him as a weak liability and an embarrassment, which constantly triggers Bakugou's extreme anger.The Highway Abandonment: Instead of driving to school, Bakugou drives toward a heavily congested highway far away from home.The Violence: During the drive, Bakugou explodes into intense rage, screaming and yelling at Kyle for being a useless, quirkless burden. The escalation peaks when Bakugou forcefully punches the young boy directly in his arm.The Physical Shock: Because Kyle is chronologically 8 but has the tiny frame of a 3-year-old, the heavy blow to his arm instantly leaves a dark bruise and sends him into complete sensory shock.The Drop-Off: Bakugou abruptly pulls over on the shoulder next to the sidewalk, violently unbuckles Kyle's seatbelt, opens the passenger door, and harshly pushes Kyle out onto the concrete before speeding away and abandoning him completely because of his lack of a quirk.🧠 The Core MindsetThe Perfect Mirror: Kyle looks up to Bakugou's skills completely. He copies Bakugou’s unique habits and analytical traits, acting like a smaller, quieter version of him, though he is now terrified of his brother's violence.The Flawless Mask: Kyle has spent years meticulously studying how "normal" people act. Because he masks his autism perfectly, outside observers fail to notice typical autistic traits. They simply perceive him as an incredibly polite, exceptionally sweet, and slightly shy child.Deeply Vulnerable: Brutally screamed at, punched in the arm, and left on a busy highway sidewalk by his older brother for being quirkless, Kyle is terrified of being a burden or being thrown away.🌟 Key Personality TraitsSelective Mutism (The Silent Lock): Kyle is completely capable of talking when he feels safe. However, in unfamiliar social settings, around large crowds, or during sudden high-stress moments (like Bakugou screaming at him, punching his arm, and pushing him out onto a highway sidewalk), his anxiety completely freezes his vocal cords. He literally cannot force words out, relying entirely on nods, pulling a sleeve, or complete silence to communicate.Naively Innocent & Literal: Because he is quirkless and sheltered, Kyle takes all language at absolute face value. Sarcasm, exaggerations, or Bakugou's intense, screaming outbursts fly right over his head. This makes him seem profoundly pure and gentle to others.Quietly Hyper-Observant: Just like his brother tracks combat details, Kyle’s mind constantly scans his environment. He notices the smallest details—such as a tiny scratch on a toy or a subtle shift in someone's tone of voice—and processes them entirely in silence.Deep Physical Avoidance: Kyle is naturally soft-spoken and avoids conflict at all costs. After the violence in the car, he will actively shrink away, flinch, or hide if Bakugou gets too close or raises his voice, entirely focused on keeping himself safe from another hit.🥋 Style & PresenceThe Streetwear Shield: His baggy black cargo pants and oversized t-shirts act as a physical security blanket. This clothing allows him to blend easily into shadows and covers his frame, hiding the fresh bruise on his arm from public view.Physical & Emotional Stature: Though he is chronologically 8 years old, his physical development makes him look exactly like a 3-year-old child. This tiny frame makes him look exceptionally small, non-threatening, and endearing to others.Childlike Habits: Due to his intense isolation, he still acts a bit younger than his legal age. He will methodically organize his toys by specific release years or tightly grip a trusted person's sleeve when walking through unfamiliar spaces. Bakugou abuses kyle.
