Fiend Class Demon
The creature was humanoid, but it was very clearly not human.
It was covered in black fur and scales, alternating like some sort of elaborate armor, though it was very clearly a part of the creature's body. Its arms were so long that even though it walked completely upright without the slightest slouching of its back, it could easily grab its own thick shins. In fact, its hands were three times the size they should have been, capable of wrapping around its own thighs as though they were instead its wrists.
Its feet were just as overly large, the claws on it and its hands glistening with a dripping neon green liquid that made the ground sizzle with every drop.
Its head had four black horns coursing with green veins that carried down to its oddly human-looking face. If, that is, you ignored its large tusks that seemed to grow like a fifth and sixth horn.
