More HMHVV sub types:
Reaper: Basically a genetically modified HMHVV-II virus which brings out the Harvester genotype to other metahumans. However whoever tweaked this basically meant this as a bio weapon and added the following weaknesses: Self destruct. 1 week after infection, victim burst into flames destroying virus and infected. Virus itself is destroyed 1 week after being released.
Manananggal: Basically a Filipino variant of the HMHVV-1 vampire. Only affects humans. dual form. Basically the victim has two form human and manananggal(which basically the upper half of the body sprouts huge batwings, fangs, claws and seperates from lower half at the stomach. ), the manananggal can switch from the human and manananggal form anytime but it would rather do so at night(due to the manananggal form suffering from allergy: Severe sunlight). It likes to eat metahuman inner organs especially infant fetuses(It regards this as a delicacy). The usual MO is the Mananggal likes to go to the roofs of houses use its thin tongue to slide down a hole in the ceiling and suck up the infant fetus from a pregnant victim...it does not like Troll or Ork infant victims(too much dermal deposits).
So powers are different for each form:
Human: Immunity(age, Pathogens, Toxins), Infection, regeneration, sapience, enhanced senses(hearing, lowlight, thermographic). Weakness: Dietery Requirement(metahuman blood & flesh: inner organs). Essence Loss 6 months).
Manannggal: Every powers and weakness of the human form with addition of: Powers: Flight, Bite, Claws, tongue stinger(used to suck up blood and internal organs). Weakness: Allergy Severe Sunlight, Allergy severe: Salt
