This SCP, the Parasee is usually passive. If in a group of 6 or more people, it will become hostile, then infect the nearest victim with the neurotoxin Substance-128, turning them into a fellow Parasee. If in a group of 6 or more monsters or fellow Parasees, it will remain passive. The more people near Parasee, the more hostile Parasee will tend to get if agitated. Please stay in a group of 1-5 people around Parasee whenever possible. 964; EUCLID
