The name Nergal (or Nirgal, Nirgali) refers to a deity in Babylonia with the main seat of his cult at Cuthah represented by the mound of Tell-Ibrahim. Nergal is mentioned in the Hebrew bible as the deity of the city of Cuth (Cuthah): "And the men of Babylon made Succoth-benoth, and the men of Cuth made Nergal" (2 Kings, 17:30).
Nergal is a recurring character in Cartoon Network's animated television series The Grim Adventures of Billy and Mandy. He is probably named after Nergal, the Babylonian god of the underworld. Nergal was voiced by David Warner in the first episodes, but he is currently voiced by Martin Jarvis.
