In his fat form, Taishiro is a large, round man, easily towering over other adults. In this form, his mouth is wide, and his nose is smaller, which gives him an odd look alongside his odd body proportions. After burning through his fat, however, it is revealed that he is pretty muscular, and his body adapts to conventional proportions. He is very friendly towards civilians and other heroes, appearing to be a playful and carefree person.
