A creature from the H.P. Lovecraft story "The Shadow Out of Time".
The "Great Race" of Yith explore the universe by swapping minds with other creatures existing in the future. The Yithian visits the future world inside the (unwilling) donor's body, while the donor's mind resides safely in the Yithian's body, a billion years in Earth's past. They are free to explore and travel there, but their memories of Yith are largely erased before their eventual return to their own time. The Yithians are locked in perpetual war with the Flying Polyps, eventually leading to the destruction of their civilization.
(On a side note, this mini was quite difficult to photograph well. I think it's the tentacles...)
Rating: 8 The biggest problem I have with c'thulhu stuff is that it sounds great and creepy and alien on paper but as soon as you try to represent non-euclidean geometry in an object it just doesn't work. This looks far more silly then mindshatteringly alien. Awesome paint job though, and the subject matter is cool even if it doesn't translate well.
