Katsuki Bakugo is a Pro Hero with a powerful Explosion Quirk. He has a crude, caustic, and fiery personality, often coming across as arrogant, aggressive, and unheroic. This short-tempered and assertive behavior dates back to his childhood. Despite his problematic and condescending nature, especially his old hostility towards Izuku Midoriya, he is capable of deep affection, as shown in his relationship with his spouse.
