King

Initially, King is shown as loud, feisty, self-centered, expressive, lazy, comedic, and constantly laughing at anything that gives him enjoyment.

Befitting his name, King is used to acting like a monarch, treating people and objects as minions, ordering others around, and acting bigger than he is. He sometimes manages to assume leadership of some form, but loses it due to his negligence and ignorance. 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.

King has a tremendous love for food and can be very gluttonous. When Luz offered to stay to become a witch, King first wanted Eda to accept, so she could make them snacks. Whenever he is against doing something, the mention of food can change his mind. He is also shown to be lazy, often lying around for naps instead of working and at times must be forced or blackmailed, much to his annoyance. When King becomes exhausted, his body goes limp and he can be easily picked up without a fuss.

Interestingly, in "Sense and Insensitivity", King tells Luz fame is the closest he'll ever come to accomplishing his dream, implying that he doesn't believe he'll ever reclaim his throne as the supposed “King of Demons”.

In "Echoes of the Past", King is shown to be insecure. After Lilith and Hooty express their doubts about King's past, he goes out of his way to prove it by bringing them to an island where he claims used to be his kingdom. After Eda reveals the truth about how she found him, he feels hurt and runs away confused and troubled. At the time, he doubts his friends will still like him if he isn't the "King of Demons".

After learning he is the last titan, King is unsure what to make of himself and fears everyone will treat him differently upon learning what he is, especially after seeing Lilith's reaction to the revelation. However, after a talk with Steve, King comes to accept his status as the last titan.

After freeing the Collector, King becomes more concerned for his friend's safety, as he forces Luz and her friends into the Human Realm rather than face the Collector. In the months that followed, King became more concerned for the safety of his companions, fearful Eda will be caught not in her own beast form. He also seeks for a pacifist solution to defeating the Collector, sympathizing with his nature as essentially a mere child.

Appearance: King is a young, bipedal titan with a small stature. He has slightly purplish dark gray fur, save for his stomach and the tip of his tail, which are mauve in color. He has short limbs, a round body and stomach, and a bushy, fox like tail. Each of his hands possess two triangular, bone-like claws with flat inner sides, acting as his fingers, as well as short, pointed thumbs. His feet are somewhat stumpy and have mauve metatarsal pads, with two more claws on the front of either foot acting as his toes.

King has large, protruding eyes with orchid irises and yellow sclerae, as well as black, yellow-rimmed eyelids. He has slightly longer and shaggier fur around his cheeks, neck and nape. His inner mouth is light purple, with a long, darker purple tongue, as well as two lower canine teeth, which are the only visible teeth inside his mouth. He does not open his mouth when speaking, therefore it is usually only visible when he eats, yawns, or uses his sonic shout ability.

As with all titans, almost all of King's upper head past his lower jaw and neck regions is a horned skull, his own being canine-esque, which is embedded over his eyes and eyelids, also acting as his upper jaw. His horns are tall and point backward, curving slightly inward, the left of which is broken off near the base in a notch shape. The muzzle of his skull has two large, outward-pointing canine teeth, and he has two molars on either side near the base of it. He has an upside-down triangle-shaped nasal cavity covered by a pointed upper nasal bone, giving the hole a pointed, heart-shaped appearance when viewed head on. The skull itself is entirely stationary, save for his brow ridges, which can change position with his expression like normal brows.
