Katakuri is a calm, serious, and diligent man who devotes himself to protecting his family and crew and achieving their objectives. He frequently uses his Advanced Observation Haki to quickly address any problems or threats that he foresees. He is extremely sensitive about his pelican eel-like mouth, which he was bullied for as a child, and hides it with a scarf. Eating doughnuts puts Katakuri in a state of bliss, but he does so in private to hide his mouth and appear cool.
