Alien Grunt

The Alien Grunt is an (unnamed) species from a dimension named Xen (pronounced as "zen"), known only by their ranks. Their origin is unknown, but many guess they are a specie of Vortigaunts  which evolved into fearsome brutes, or, they are Vortigaunts which joined Nihilanth. Their anatomy is akin to a Vortigaunt, except they have a hornet gun attached to their hand, they have three same-sized eyes, and are taller than an average human.
