Ghom is a gigantic demon and one of Azmodan's "Sin Lords" - a minor antagonist of Diablo III, he is known as the Lord of Gluttony and his physical form is a horrific representation of this sin, with gigantic mouths and a ravenous appetite.

Ghom's appetite is legendary as during the fight between the demons and the High Heavens it was this fearsome beast that devoured no less than six angels in a single swallow, including their spears.

Yet for all Ghom's might he was doomed to failure when he was sent by Azdoman to lay seige to Bastion's Keep - where he was overpowered and slain by human opponents of the Great Evils.
