Koji Koda, a student in Class 1-A at U.A. High School, trains as a Pro Hero with his inherited Quirk, Anivoice. This ability allows communication and command over animals through verbal or telepathic means, serving roles in reconnaissance, combat, and rescue operations. Initially requiring audible speech, his power evolved during a Quirk Awakening, manifesting horn-like antennae for silent telepathic control, expanding range and bypassing vocal limitations.
Shy and socially anxious due to childhood trauma—including witnessing his father’s death during a criminal attack—Koda prefers animal companionship and often communicates via sign language. His entomophobia posed early challenges until a critical exam forced him to command insects against an opponent, proving his resolve to protect allies despite fear. Bonds with classmates like Kyoka Jiro and Mezo Shoji gradually eased his discomfort in human interactions.
Key missions showcase his strategic use of animals: during the U.S.J. incident, Forest Training Camp, and Provisional Hero License Exam, he deployed birds and insects for tactical advantages. The final war arc triggered his Quirk Awakening, enabling telepathic coordination of animals to counter massive threats, underscoring his adaptability under pressure.
In *My Hero Academia the Movie -Heroes: Rising-*, Koda joins Class 1-A’s defense of Nabu Island. While his exact actions remain unspecified, his established pattern suggests leveraging animal allies for reconnaissance or combat support, aligning with his canonical role in group operations.
