Nergal is a former antagonist of the series. He is a demon-like being from the Center of The Earth who has snake like tentacles growing from his back. These tentacles can electrify people and act as extra arms. He wears a red and black business suit. He is named after the Babylonian fire god.

He started out and first appeared as a minor antagonist of Grim and Evil, who was a rather lonely creature who yearned for friends and was something of an adversary of Grim, Billy and Mandy, but starting from his third appearance he became more smoothly affiliated with them and even became a member of Billy's family after marrying Aunt Sis, resulting in him finally making peace with the main characters.


Only in the episode "Love Is EVOL Spelled Backwards" and the video game, Nergal actually had friends (they're also minions). They are called "Nergalings," and are his only friends.

Nergal is often seeking friendship, but is typically unsuccessful. Nergal later married Billy's Aunt Sis. After a string of unsuccessful attempts to woo her, it was Billy's backfired attempt to sabotage Nergal's and Sis's date that won her over, thus making Nergal Billy's paternal uncle by marriage. Nergal settled down into a happy marriage with Sis.


He has black skin, green and purple eyes, green tongue and green teeth. He wears a black and red suit that resembles a business design. His feet are also supported by short heels, giving the appearance of boots.


Nergal can electrify enemies by ensnaring them in his snake-like tentacles, and teleport in a flash of pure white light. His tentacles also function as a method of transportation as seen when he extends them to emerge from underground in a spider-like matter and strong enough to carry people on his back.

  • Nergal's character is most likely based to at least some degree off of the Sumerian God of the same name. Nergal was the Sumerian ruler of the Underworld, war, pestilence, the summer solstice and god of the dark aspects of the Sun [which could take away life, especially since Sumeria was situated in what is today the Middle East, which is a desert region].
  • Nergal's minions, "Nergalings" could be a reference to Warhammer's "Nurglings." Both are dimunitive demons that resemble their masters. In the case of the Nurglings, they resemble Nurgle, the plague god.
