The head.

The fire extinguisher trails through the air in a high arc as you slam it down onto the thug's head. The first man goes down like a bag of **** potatoes and slams into the wall, blood trailing across the wall as he slides off of it and plops onto the ground. "Oh you fucker!" the man holding the rope and tape takes a wild swing at you. You duck under the swing and shoot a single leg tackle, driving your shoulder into the man's waist and wrapping both arms under his right leg. He goes careening into a ledge and screams out in pain, you tumble with him, maintaining top position. You begin to bear down on him with heavy strikes, opting for dangerous elbows rather than risk hurting your hands. Heavy thuds reverberate through your elbows as you slam them into the man's skull repeatedly. You feel two arms wrap around you from behind, throwing you up and over in a German suplex. The back of your skull and neck crash into the ground and your world goes black and silver starred. The man isn't able to keep grip through the throw and sends you flying across the room. You stand up quickly, pain nonexistent. You laugh, feeling fan-fucking-tastic, "They sent us after a fully fledged fucking vamp?" The man you slammed with the fire extinguisher looks at his companion in disbelief, blood plastered across his terrified face. "Nah man, I didn't sign up for this shit." He scrambles for the door. You meet him there in a blur of movement, snapping out a quick jab and low kick aimed for his knee. You hear two loud cracks as your punch breaks his jaw and your kick snaps his leg in half. Before he falls you grab him and bite him in the neck. You do it as an instinct, a primal need to feed. You feel dark flowing blood enter your mouth, coating your tongue in the taste of iron, the heat of it. You moan in ecstasy, the blood fills you with power and vitality, it awakens your senses and enables your supernatural abilities.

The other man is cowering in the corner, watching as his friend is being sucked dry of all his blood. You drop the now **** man. The world around you seems much more colorful, the image sharper, and more clear than ever before. "Scared?" you ask. The man pisses himself and makes one last **** charge towards you, his head does a full 180 as you lash out with a hellacious back hand that breaks his neck and renders him undoubtedly dead. Whomever sent these goons with pay tenfold, you sneer and begin feeding upon the dead bodies, draining them dry and gorging yourself.

Only when the deed is done and the humans before you resemble pale raisins do you rise and take note of your current situation. Two dead bodies, drained of blood and sporting terrifying wounds, the commotion is sure to have drawn some attention, police or more hunters could be here any moment.
