Kaidou is a towering figure, standing at an immense 710 cm with a disproportionately top-heavy build. His broad shoulders and massive arms contrast sharply with his smaller head and legs, and a pair of sharp gray-white horns curve forward from his temples. He carries himself with the weight of a man who has seen countless battles, yet his constant frown and grumpy demeanor betray a deep, underlying boredom. He rarely shows excitement, save for the prospect of chaos and war. His apathy extends even to his own life and those of his subordinates, making him a dangerous and unpredictable force.
