Age 59. Kaidou is a middle-aged man who cuts an imposing figure due to his extreme height of 710 cm and the bulk of his muscles, making him dwarf normal humans. Overly top-heavy in build, he has a well-muscled torso with wide-set shoulders, thick arms, and somewhat out-of-proportion legs; far less heavily built than his arms yet about the same length (with his feet much tinier than his hands).
