Mutilator
The Mutilators are massive horrible abominations of flash and metal, who live only to RIP AND TEAR. They are often called melee-oriented Obliterators, but though crunch-wise (and model-wise, to the extent of having the exact same torsos and legs) they are practically identical, fluff-wise they are nowhere near. Mutilators were once Terminator champions, who was so obsessed with close combat, that they merged with their weapon into one being. Apparently, spending 90% of your time in the fucked up hell-dimension of the Eye of Terror you can do such things without any daemonic techno-virus help. So now their bodies are covered in grown-in terminator armour, power weapons, chain weapons, lightning claws, and various other sharp objects, as well as their souls, which have merged in all of the machine-spirits of all the weapons they have absorbed. Unlike Obliterators they still can speak non-binary language, but being absolutely batshit-insane butchers they rarely have anything to tell.
