Threat Assessment: 8. Everything a regular vampire is ramped up to ten. Meth head vampires that are berserkers, incredibly hard to kill, and have long sucker mouths. Definite nightmare fuel.
Limitation: Daylight, ultraviolet light, penetrate the heart if you can get through the natural body armor. With the exception of the leader they don't seem to exhibit too much intelligence and have a junkie mentality.
