Mutilator

A Mutilator is a vile Chaos Space Marine whose intense lust for battle and quest for the simple purity of the blade have warped his physical form until he has fused, body and soul, with his melee weaponry. Mutilators seek not only to commune with powerful war-spirits but to absorb them, assimilating the Warp-spawned power of the various close combat weapons into their own souls and fleshmetal bodies so that they can manifest corrupted versions at will. The exact origins of the servants of Chaos known as Mutilators is not exactly clear. It is generally believed that the first of their number were originally Terminators of the Traitor Legions who specialised in close-quarters fighting, but as with all who harbour an obsession within the Warp, they grew to become the incarnation of the murderous desires in their hearts.
