Globgor is a monster with red skin covered in darker red tiger-like stripes, long white hair tied into a topknot, four yellow eyes with slitted pupils, pointy ears and nose, short horns, and fanged teeth. He wears a black boxer-briefs-like garment, gold wristbands, and a ring on his left ring finger.
In portraiture and other dramatized depictions, Globgor stands a little more than twice the size of Eclipsa. In "Conquer", he is shown to be of gigantic size.
According to a passage in "Into the Wand" and trial testimony in "Butterfly Trap", over 300 years prior to the series' present day, Queen Eclipsa Butterfly abandoned her husband, the Mewman king Shastacan, and the kingdom of Mewni, to be with the monster Globgor. They eloped to an ancient monster temple and bore a half-Mewman, half-monster daughter, naming her Meteora.
The Magic High Commission later discovered where Globgor and his family were hiding. Globgor was crystallized and remained imprisoned at the temple, while Eclipsa was imprisoned in the Crystal Dimension for breaking the Mewman taboo of fraternizing with a monster. Their daughter Meteora would later be disowned by King Shastacan, adopted by St. Olga, and replaced with the peasant girl Festivia.
At the end of "Conquer", after Meteora is defeated and reverted to an infant, Eclipsa brings her to the Monster Temple and discovers where Globgor still lies in crystallized stasis.

- Between "Rest in Pudding" and "Conquer", Glossaryck only says the word "Globgor". At the end of "Conquer", it is revealed he was trying to forewarn Star about him.
- Globgor has multiple similarities to the DC Comics villain Trigon, from the red skin, four yellow eyes, horns, imposing size, and having a hybrid child with a mystic. Trigon had a daughter with a human woman who became the superheroine Raven.
