Wisper

You may not see me, but am there at your every move, stalking you until... I kill you.

Whisper
He is a faceless figure. He stalks his victims before killing them. His voice is said to be like a wisper. If he's stalking for you, you and only you will here him, see him or die from him.

Origins
Makar Yermolayev was a quiet man, often mumbled to himself. He generally talked very quietly. Makar was on a Swedish research team studying invisibility tech. Makar voted for human volunteers. He himself would be the first. After the tests, he said he felt strange. Twenty minutes after the test, he became pale and others scientists noticed loss in facial feature. Suddenly he dissapeared. They could still hear him, but see or feel him. He reported a mass of voices were in his head... controlling his thoughts and actions. Then he was gone. No one could hear, see or feel him. Days later over half the research team had been murdered. His current warabouts are unknown. His current warabouts don't want to be known.
