Jason

From the White Wolf Wiki, the most complete White Wolf reference

Jasons are one of the most dangerous and misunderstood breeds of Spectres. Jasons are creatures that specialize in taking over weak-willed or empty bodies and using them to commit atrocities beyond belief. Other than the death they leave in their path, a Jason embodied can be identified by looking at the eyes, which retain a reflection of the Oblivion that spawned it. A Jason was responsible for Terrel and Squib’s famous Forest Hills incident.
