Legato Bluesummers from Trigun
With a sinister fashion sense and the ability to screw with both your mind and your body, he exists only to kill you and all your loved ones. He takes a perverse joy in torturing Vash, from planting violent images of children being killed in his mind to forcing Vash to shoot him in the head, thus ending Vash's pledge to never take a life. If you annoy him, he'll make you kill yourself and everyone you hold dear with your own hands, all while he enjoys a nice sundae or tiramisu. You are vermin, and Legato is determined to obliterate all vermin.
