Koji Koda, a student in U.A. High School’s Class 1-A, stands out with his rock-like visage and muscular frame. His rugged, horn-like cranial protrusions, inherited from his mother, amplify during the Final War, boosting his Quirk’s telepathic reach. Initially clad in a yellow suit with red accents and a duck-bill mask, his hero costume evolves post-graduation into a streamlined design with a strap mask. Hailing from Iwate Prefecture, Koji attended Fueshia Middle School before U.A. His Quirk, Anivoice—a genetic gift from his mother—grants communication and command over animals. Though gentle and reserved, his entomophobia, rooted in a childhood trauma involving insects and a carcass, once limited his combat effectiveness. He conquers this fear during the Joint Training Battle, collaborating with Eijiro Kirishima to deploy swarms against adversaries. Koji’s Quirk matures from vocal-dependent animal control to telepathic mastery as his horns lengthen in the Final War, eliminating the need for speech. Key techniques like "Hitchcock Birds" and "Bugging Out" prove pivotal, aiding missions such as rescuing Mahoro and Katsuma Shimano on Nabu Island through avian reconnaissance and assisting Mezo Shoji. He contributes to critical U.A. events—the U.S.J. attack, Sports Festival, and Provisional Hero License Exam, where bird flocks disrupt rivals to secure victory. Partnering with Kyoka Jiro against Present Mic in the Final Exams, he leverages insects to ambush the teacher, showcasing his growth. Post-graduation, he serves as Tentacole’s pro hero sidekick, specializing in animal rescue and ecological initiatives. Despite his intimidating build, Koji’s shyness leads him to favor sign language, though his loyalty shines in crises. His dorm room hosts his pet rabbit Yuwai and nature-themed decor, reflecting his affinity for wildlife. Bonds with classmates like Fumikage Tokoyami and Rikido Sato form through shared trials, such as the Sports Festival cavalry battle. Statistically, his high physical strength offsets lower speed and combat ratings, cementing his role as a strategic support specialist. By harmonizing Quirk versatility with hard-won confidence, Koji emerges from obscurity to a dependable hero addressing human and animal emergencies. His journey epitomizes triumph over fear and the application of unique talents for collective good, driving his mission to safeguard ecosystems and champion animal rights.
