Kung Fu Dugong is a minor but memorable animal character in One Piece. He is a dugong trained in martial arts by the Kung Fu Dugong group and later appears on Rusukaina, where he serves as a comic yet capable creature. He can fight using kung fu techniques and is shown as a loyal, disciplined animal rather than a simple background gag. In the story, he mainly adds humor and flavor to the world while also demonstrating the series’ playful habit of giving unusual creatures distinct personalities and skills.
