Dokku is a 36-year-old, rather portly man with short brown hair and a receding hairline. He wears square-framed glasses and has a short mustache and pointed beard. He has the complex tattoo of the Tonika village militia on his right hand. As heard in the episode, Leo calls him fat, while Miina objects. As a young man he was very thin. He has many large scars on his body. He usually wears casual clothes that contain a light yellow t-shirt and dark blue pants with brown crocodiles.
