Not much about Rhombulus' past is known, but he is part of the Magic High Commision and created by Glossaryck. He also imprisioned Eclipsa, the Queen of Darkness (Star's ninth great-grandmother).
Personality and Traits
Rhombulus has a very short temper and will quickly engage those he thinks have insulted him. Rhombulus' snake hands have minds of their own, and they sometimes act as the voice of reason for Rhombulus' reckless ideas.
Rhombulus is a muscular creature with diamond-shaped crystal for a head and eye, and snake arms. These particular items were all that remained of him after magic was erased at the end of the final episode.
- Rhombulus' name is a portmanteau of "rhombus", a four-sided shape, and Romulus, the legendary founder of Rome.
- According to Star and Marco's Guide to Mastering Every Dimension, Rhombulus was created by Glossaryck to serve as the Magic High Commission's muscle.
