Chaugnar Faugn appears as a "statue" made from an unidentifiable element of a disgusting humanoid hybrid creature which combines the very worst aspects of the octopus, elephant and human being. His proboscoid trunk sports a horrible lamprey-like mouth at the tip, which Chaugnar uses to drain his prey of their essence. This process also causes the victim to slowly transform into the likeness of The Elephant God himself.
Chaugnar Faugn is also said to have five "brothers," but evidence would suggest that these beings are actually all avatars of the same interdimensional entity.
Originally from a dimension very different from our own, Chaugnar Faugn travelled to Earth in its far distant past. Discovering that the dominant indigenous life was in the form of primitive amphibians, he proceeded to create a race of humanoid servant beings, naming them the Miri Nigri. Much later in Earth's prehistory, these Miri Nigri would eventually interbreed with early Man to create the horrible, cannibalistic Tcho-Tcho race.
In the mid-twentieth century, an archaeological expedition sent by the Manhattan Museum of Fine Arts to Asia returned with what was assumed to be a statue of Chaugnar Faugn. Not realising what it really was, Chaugnar killed several people clandestinely in the night before embarking on a rampage across the city, killing and feeding upon many more.
After tracking Chaugnar to the shore where it became trapped in mud by the river, a group of scientists and a mystic were eventually able to employ an experimental "anti-entropy ray" on the beast, which reduced it to the primeval components from which it was formed, although whether this would be enough to permanently banish Chaugnar from the Earth remains to be seen.
