Am-Heh

In Egyptian Mythology, Am-heh was a minor god from the underworld, whose name means "devourer of millions". He was depicted as a man with the head of a dog who lived in a lake of fire. If the Lake of Fire was not enough, his ferocity was augmented by him having the face of a demonic dog and an appetite for sacrifice.
Not much is known about Am-heh only that Atum can keep him at bay.
