Nergal is a character in Grim Tales. He is the grandfather of Minimandy, the uncle of Billy, greatuncle of Grim Jr. and father of Nergal Junior. He originates from the Cartoon Network show, The Grim Adventures of Billy & Mandy.

Grim Tales


Nergal was often seeking friendship, but is typically unsuccessful. Nergal later married Billy's Aunt Sis. After a string of unsuccessful attempts to woo Sis, it was Billy's backfired attempt to sabotage Nergal's and Sis' date that won Sis over, thus making Nergal Billy's maternal uncle by marriage. Their marriage eventually resulted into the birth of Nergal Jr.

After Nergal Jr. grew up, Nergal returned to the Center of the Earth where he became the father of all the Nergalings in the Underworld. If Sis was still alive at that point is unknown, as she hasn't been seen in the comic. Nergal lost most of his contact with his son, and only could interact with other Nergalings.

From Down Below

He first appeared in a picture that was inside of the book of Grim as one of the many adventures they have made.

He later appeared when Grim Jr. just recieves his Nergal Demon powers from Minimandy. He explains to Grim Jr. that when a Nergal Demon gave it's right eye to another person, when dying, him or her gets the powers of that Nergal. But, if a Nergel gives another person else their left eye, that it is a sign of marrige, or purposal.

Later, he is seen when Grim and Clockwork entered the belly of the Demon Reaper where Grim had a discussion with him about his family and he revealed that the father of Minnie was actually Nergal Jr. and that Grim only gets childs when he does an abortion. When they saved Junior's soul Nergal leads them to a way out.

Later, when Junior's soul gets eaten by the Demon Reaper he appeared out of Junior's body. He helped Junior and Minnie to escape, but him, himself died. Nergal Jr. saw his dead father lying on the ground, and felt terrible.

What About Mimi?

When Junior was upset and was fighting with his Nergal powers, Nergal's soul came back to talk with Junior about him going up against his mother in order to protect Mimi and that its up to him to protect and help her.
