The Owl House Wiki

Professor Hermonculus is a minor character of The Owl House. He is a teacher at Hexside School of Magic and Demonics who teaches students in the abomination track. He originally awarded Amity as top student until he later promoted Willow to the position.


Professor Hermonculus is a stubby and short humanoid creature with pointed ears, a round beak-like mouth with two fangs on the top row of his teeth, and two claws on each foot. He has green, chin-length hair with a large bald spot on the top of his head. He has inward-facing green eyebrows and a small green beard. He wears orange tinted circular glasses with no temples and narrow, slanted eyes. He has defined cheekbones as well.

As for his outfit, Professor Hermonculus wears a black shirt and pants with an oversized purple coat with a red lining. He wears a light silver bow tie around his neck. He is carried by a mauve-colored abomination with a sad and drooping face.


Professor Hermonculus is shown to be a strict teacher with high standards. He seems to be only satisfied with a few students who show great potential in their magic, such as Amity Blight. He also holds grudges against students who leave his class. He seems to be an egotist, as he is almost always shown being carried by one of his (presumably) abominations, despite shown to be perfectly able to walk in "Any Sport in a Storm".

In addition to his strict nature, Professor Hermonculus also tends to behave unfairly towards students, especially those who have aroused his envy. This is seen when he wanted to ban Willow from managing a Flyer Derby team simply because of his grudges. He also has a slightly sneaky side, throwing Willow off her wand during the flyer derby match, although he was already eliminated by that point, a rule violation that also earned him the disapproval of his own team.


When he was younger, Professor Hermonculus played flyer derby with Principal Bump.

In "I Was a Teenage Abomination", upon seeing the class' poor presentation of abominations, Professor Hermonculus warns his students that they will receive extra homework should they keep failing like this. Amity wishes to present her abomination, but he tells her to wait until she is last, instead calling on Willow to present. Unbeknownst to him and the entire class, Willow's "abomination" is actually a human disguised as one - Luz Noceda. Impressed with Luz's performance, Professor Hermonculus strips Amity of her top student badge, giving it to Willow as well as boosting her grade, much to Amity's ire. Later, during lunchtime, Amity catches Luz eating a sandwich, something which abominations are unable to do. Furious, she demands an explanation, shaking the human violently. At that moment, Professor Hermonculus walks in, and seeing his student, reprimands her for her behavior. Despite Amity's protests, Professor Hermonculus orders her to head to Principal Bump's office immediately.

In "Covention", Professor Hermonculus is among the crowd attending Bonesborough's annual covention. Later, Professor Hermonculus glances at Luz as she attempts to apologize for what happened during her last visit to Hexside in "Something Ventured, Someone Framed". In "Enchanting Grom Fright", Professor Hermonculus is part of the many guests attending Grom.

In "Any Sport in a Storm", Professor Hermonculus attends the club fair, expressing his grudge against Willow for leaving his class and feeling skeptical that she can defeat his team in flyer derby, let alone lead one. Despite his words, Willow remains convinced and leads her team against Professor Hermonculus' team at the grudgby fields. They win, and bitter, Professor Hermonculus finally registers her team, named the Emerald Entrails by Hunter.
