Chaugnar Faugn.

The Elephantine Horror From The Hills, Chaugnar Faugn, is a massive being, easily the size of the Giant Squid, and it is known best for its place in the Tcho-Tcho people's mythology, as a God. Chaugnar Faugn appears as if he is a massive hideous idol, made of material unknown, combining the worst aspects of octopus, elephant, and human being. When Chaugnar Faugn hungers, it can move incredibly quickly for its size and use its lamprey-like "trunk" to drain the blood from any organism it encounters.

Chaugnar Faugn came to the Earth from another dimension eons ago, possibly in a form other than the one it later assumed. Upon arriving, he found the dominant lifeform to be only simple amphibians. From these creatures, he created the Miri Nigri to be his servitors. The Miri Nigri would later mate with early humans to produce hybrids that would eventually evolve into the horrid Tcho-Tcho people.
