Yuga Aoyama is a flamboyant and vain student in Class 1-A at U.A. High School in My Hero Academia, known as the "Shining Hero: Can't Stop Twinkling," whose Quirk is the "Navel Laser," a powerful beam he shoots from his navel. He was revealed to be the "U.A. Traitor," forced to spy for All For One, but ultimately renounced his allegiance to help the heroes, eventually becoming a Pro Hero after graduating. His Quirk, originally given to him by All For One, causes him pain, but he uses a special belt to channel the energy and has trained to control it, even awakening it for greater power. Key aspects of Yuga Aoyama: Hero Name: Shining Hero: Can't Stop Twinkling. Quirk: Navel Laser, a powerful beam that can be fired from his navel and, with his support gear, from other parts of his body like his shoulders and knees. Origin of Quirk: He was born Quirkless and received his power from All For One, making his body incompatible with it, which caused him pain and led to his role as a spy. Role as Traitor: He was coerced into working for All For One, providing information to the League of Villains, but eventually chose to help the heroes in the Final War. Support Gear: He wears a special belt and other equipment to help channel his laser and manage the side effects, which he initially disguised as a birth defect. Flamboyant & Vain (The Façade): Aoyama loves being the center of attention. He strikes dramatic poses, spouts French phrases, and boasts about his Navel Laser quirk. This dramatic exterior is his way of trying to stand out and feel special. Deeply Insecure: Beneath the sparkle, Aoyama struggles with heavy self-doubt. He was born quirkless and was granted his quirk by All For One through his parents. Because his body isn't biologically adapted to the quirk, he suffers severe intestinal distress if he fires his laser for too long, a defect that makes him feel inferior to his peers. Compassionate & Empathetic: Aoyama deeply cares for his classmates. Because he and Izuku Midoriya both struggled with highly taxing, uncontrollable quirks early on, he felt a deep kinship with him. He is also highly observant of other people's feelings and relationships. Burdened with Guilt: He was forced to act as an unwilling spy for the villains to protect his parents. Despite his outward bravado, he is wracked with remorse over this betrayal, viewing himself as a "despicable villain" but consistently attempts to make up for it through quiet, selfless acts of heroism.
