Gelmud prided himself as a high-class Majin. He was the type of person who would hide his true intentions behinds the language of a polite gentleman.
For 300 years, he had been planning a species war. However, Veldora's disappearance caused his plans to spiral out of control, so he gave up on inciting a war between the named monsters born from the goblins, lizardmen, and other such races.

He is clearly above an A-rank and has a regeneration skill.
