Orcus - Demon Prince of the Undead

I drew this image to supplement an AD&D adventure that I was creating. The being is from Monster Manual I, Gary Gygax: "Orcus appears as a grossly fat demon some 15 feet tall. His gray body is covered with goatish hair, and his head is goat-like, although his horns are similar to those of a ram. His great legs are also goat-like, but his arms are human. Vast bat-like wings sprout from his back, and his long snaky tail is tipped with a razor sharp poisonous tip."
