A living pool of black ooze that is postulated to formerly be a human male. It appears to be pollutant based. Specializes in stealth. Modus Operandi appears to be suffocation of its victims by blocking air passages and filling the lungs with the black ooze that makes up its body. Speaks in thick German accent. Has demonstrated the ability to fling its murky form at potential victims, and has been seen turning into a gaseous form to escape. Its insubstantial form makes it an excellent infiltrator. An known agent of The Cadre of Gentlemen.
