Koji Koda, the Petting Hero Anima, evolves from a timid U.A. High student into a professional hero, balancing a towering, muscular frame with a gentle demeanor. His distinct rock-shaped head, peach-toned skin, and horn-like protrusions—inherited from his mother—gradually lengthen, later unlocking telepathic animal communication. Costume changes mirror his growth: a yellow bodysuit with crimson accents transitions to a duck-bill mask during the Provisional License Exam, eventually streamlined post-graduation. Profoundly shy, Koji favors sign language and shuns confrontation, yet his bond with animals defines him. He houses a pet rabbit and surrounds himself with animal-themed decor, contrasting his imposing exterior. A crippling fear of insects tests his resolve, but he conquers it during the Joint Training Battle, collaborating with Eijiro Kirishima against Jurota Shishida by strategically deploying arthropods. His Quirk, Anivoice, begins as vocal commands to creatures, expanding through rigorous vocal training to amplify range. Post-Final War, his horns enable silent telepathy, circumventing vocal strain. Tactics like summoning bird swarms ("Hitchcock Birds") for aerial strikes or insect hordes ("Bugging Out") to disorient foes prove vital in missions, from rescuing Mahoro and Katsuma on Nabu Island to aiding Mezo Shoji against Nine. Growth arcs highlight resilience: Kyoka Jiro’s encouragement spurs him to defeat Present Mic using insects in the First Term Final Exam. At the Provisional License Exam, he directs bird flocks to outmaneuver rival schools. By the Final War, he orchestrates animal-coordinated strategies, showcasing tactical leadership. Post-U.A., he supports Tentacole as a sidekick, leveraging his Quirk for reconnaissance and rescue. Though physically robust (4/5 strength rating), evidenced by breaking Shishida’s grip, urban environments limit his animal-dependent tactics. Internships with Pro Hero Wash hone his communication versatility. A defining moment sees him confidently conveying Principal Nezu’s message to Izuku Midoriya, symbolizing his shift from reticence to assertive teamwork. Koji’s journey—marked by overcoming phobias, refining Quirk mastery, and embracing supportive roles—cements him as a hero who thrives through empathy and adaptability.
