Kinda exotic supervillain concept, would like some help

[FuelDrop]

Okay, so this is a bit of a high concept kind of villain, but here it is:
It's a sentient mind controlling hive mind demon virus. It infects people and uses the infected as puppets. Everyone in the hive mind has access to the skills and knowledge of everyone else in the hivemind, but if anyone removed from the hive mind (such as by being cured) then they don't retain anyone else's skills or memories and the hive mind loses access to their skills.

Infection vector should be fluid transfer, since otherwise this epidemic could get seriously out of hand very quickly (the PCs will need to find patient 0 to get a pure sample and work out the cure, then work out a way to track down the victims before the water supply can be contaminated).

I am just REALLY not sure how to represent this in game stats. I mean Dominance is obvious, and maybe some kind of Affliction, but beyond that...
