King's wanted poster depicts him as a big man with short hair, sideburns, a button nose, and a sneer. Ten years ago, he wore full-body light green armor with a helmet that fits the size of his human form. He wears an enlarged version of the clothes he wears as a fairy, though he can freely change the clothes he wears in this form. In his human form, he looks almost exactly like his wanted poster large, fat and more ragged, perhaps hinting at how humans look to fairies. Despite being a fairy, he has yet to grow visible wings. He also carries a green leopard pattern pillow which is actually a transformation of his spear Chastiefol. He wears a long orange and an aqua sweatshirt with a hood and navy blue sleeves, quarter-length navy blue pants, and short boots with large buttons matching his hoodie.
King's fairy form resembles a young boy with short brown hair, a high forehead, thin eyebrows, and brownish-orange eyes.
