Like all Asini, Illusion King has two forms, which he shifts between both freely. As a human, King is a short, childlike Asini, looking even younger than he actually is. Illusion King's features are soft, rounded and very non threatening. His eyes are an unnatural green, but lack the reflective trait many Asini carry in human form. One eye is always covered with a black eye patch, regardless of the fact both of his eyes are perfectly fine. Dark brown hair is unkempt, and falls shortly in waves around ear level. His clothing trends to be dark, wearing jackets and coats that are far too big for his skinny frame. As an Asini King is a bit more human than the average, able to hide his race in public. The traits that stand out are his long furred tail, tipped with a self illuminating whips of green. Illusion King also has feet that end in three toed paws, also trailing with the same green glow. In his more beastly form, King is vaguely dog like, with a high arched back, and long brown fur covering his whole body, spare scaled spots on the top of his arm, leg, belly and tail. These ares are covered in glowing runes. His most stunning feature is a hardened skull like mask that covers his face, this item is a part of his body and not removable. In this form, his green eyes do catch light, and glow along with the runes on his mask.
Reflecting on his overly youthful appearance, King shares the same inner characteristics of being child like in his world views and interactions with others. Illusion King being born after the fall of Asis gives him a very unique, and more innocent view of the world, never having experienced the splendor of how things use to work, this some times comes with much friction with other Asini. Curious, and unafraid of new things, King can also be rather naive at times in regard to the more complex, adult world around him. One can never be sure if he'll approach new situations with childlike curiosity, or a more logical, if not a little cryptic method.
