First off, let me say that this is not my design. The original maker of this alien is Drakar006. I copied him entirely. But I've spoken with him, he said it was okay, plus I don't think he ever submitted it to the Realm. So I'll do it, since it's such an awesome design. (To be clear, I made this figure with my aliens, painted it and everything, but the credit goes to Drakar006 for designing it.)

Now for the figure: I believe it's from one of the AVP games for PC, with a few modifications to the game's design.

It was made by combining a NECA dog alien with a warrior alien, some fodder pieces, and a complete re-paint.
