King is a young, bipedal titan with a small stature, short limbs, a round body and stomach, and a bushy, fox-like tail. Almost all of his head is a horned, canine-esque skull.

King is loud, feisty, self-centered, expressive, lazy, comedic, and constantly laughing at anything that gives him enjoyment. Befitting his name, he often acts like a monarch, treating people and objects as minions, ordering others around, and acting bigger than he is. King hates being called cute and being treated like a baby, yet due to his small size, he has to rely on accessories made for infants, such as high chairs and baby carriers. He also has a tremendous love for food like cupcakes and often lies around for naps instead of working.
