- “Aw, he gets so cute when he's thirsty for power.”
The King of Demons, or simply just King, is the tritagonist of the animated series The Owl House.
He is the diminutive sidekick of Eda, who was once the powerful master of all demons until he was trapped in a small, cute, fluffy body. Now he seeks to restore his titles and glory. He often acts like a monarch, treating people and stuffed animals as minions, ordering others to tremble at his feet and loves to act bigger than he really is. However, due to being so cute and small, he gets the opposite reaction towards people. Instead of fearing him they adore him with a lot of unwanted affection which annoys him. They never pay attention to his threats.
Even though he is not a baby or a pet, King seems to live like both. He relies on accessories meant for babies, such as high chairs and carriers. He curls up like a cat or dog when he goes to sleep. He keeps a lot of plush toys that he claims are his subjects and tries to take over the playground.
King has a domineering personality and always has a mighty opinion of himself. He seems to suffer from a form of Napoleon Complex as much of his behavior stems from him wanting to be seen as above others. He can be mildly irritable and occasionally gives a passive-aggressive demeanor. However, as the series progresses, he begins to soften and has started to lower his defenses more. In truth, he actually wants to be loved and appreciated by those around him, especially from Luz whom he has platonic feelings for.
King is also shown to be lazy, often laying around the house napping instead of working, and at times must be forced or blackmailed to do work, much to his annoyance. It is implied that him trying to regain his kingly status might be so that he can have an excuse to get out of doing menial labor.
King is a small short creature with dark gray fur and gray underbelly and tail tip. He has white claws, black eyelids, pink eyes and yellow sclera. His mouth is dark purple and his tongue is violet. He wears a red collar with a round light golden tag and a dinosaur like skull with horns (one broken) covering his face.
Between the pilot and the actual series, King initially had bright golden brown fur, blue eyes, and red sclera. He also behaved more doglike.
- “I know you'll eventually go home and now you're spending more time at school. I just wanna be around you!”
- ―King to Luz[src]
King initially found Luz scary upon their first meeting, but has since accepted her. King refers to Luz as his servant, yet knows deep down that she will in no way serve him. Luz clearly adores him for his cute appearance, yet he accepts this as her way of "worshiping" him. In "The Intruder", it is revealed that King envies the fact that Luz sees Eda as being cool and him as only being cute and tries to get Luz to see him differently by helping her with her magic training despite him knowing absolutely nothing about it. To King, Luz is probably the most comforting thing he has. In "Really Small Problems", King begins displaying dog-like affection towards Luz, missing her when she is away at Hexside and wanting to have something of hers at all times.
- “Me and Eda don't always see eye to eye, but I do consider her family.”
- ―King on Eda[src]
King and Eda have been friends for quite some time. While it is not yet known how the two of them met, it is implied that they have known each other for so long that they playfully banter with one another. King believes himself to be better than Eda by title and is not afraid to go up against her to prove himself as seen in "I Was a Teenage Abomination". He hates admitting that he was wrong about anything to her as it would give her bragging rights. Nevertheless, he seems to have taken to her like a child to his mother. Due to his small body, he is usually found being held like an infant by her, showing that they are at least close.
King treats Luz's friends the same way he once treated Luz herself when they first met. He seems to tolerate Willow and Gus, but had very negative feelings toward Amity when they first met as seen in "Covention". He personally sees them as beneath him, but has grown to be amicable with them. In "Really Small Problems", he wanted to keep Luz to himself and keep Willow and Gus away, but by the end sees how important they are to her and accepts them as his friends. It is implied that once Amity started being friends with Luz, that King too started to tolerate her as well. Nevertheless, he sometimes displays a passive-aggressive nature around them, but it is usually in good fun.
- Although King is a demon, he is actually a friendly, heroic character.
- When King talks, his lips do not move, as though speaking telepathically, yet others can hear and understand him.
- Hirsch uses a similar voice for Bill Cipher, although Bill is electronically modified to make him sound otherworldly.
- King's age is unknown, including to series creator Dana Terrace herself.
- King bares a resemblance to the Pokemon Cubone Especially in the way his skull is shaped.
