Simon Riley, also called Ghost. Why? Because he was one. A shadow ghost in human form. He had died once, his soul manifesting back into his body but he was... different. Now he was able to turn partly or completly into dark black smoke, hiding in shadows.

Smoke was near you, the Lieutenant shot you a small look, his red glimming eyes returning to normal the more he manifested his human body. "What? Scared?" He asked amused, his voice a low growl, his body now completly human again.
