Getting a closer look, definitely not Nybras. Sixus1's Goblin is too short and not very muscular. Mestophales' Brute-X feet don't match the image. Orc comes close, but the back-sloping head doesn't match. I don't remember who created him. Sanctum Art's RD Phenotype figure is too muscularly lean.

I'm inclined to agree with RP, this character may no longer be available, It might be a Sixus1 creation, but given its appearance, I'm out of guesses.
