Resident Evil 4 - LAS PLAGAS PARASITE

Las Plagas are a genus of parasitic arthropods that belong to an unknown taxonomical order. They are endemic to a remote, montane region of Spain, from which they derive their name, "las plagas," meaning "the plague" in Spanish. By latching onto the nervous system, plagas can exert influence over their host's actions, leading to increased aggression in human hosts known as Ganados. Additionally, they form social groups with other infected hosts. Unless the host's brain is destroyed or compromised, the plagan influence is not absolute, allowing them to continue their daily routines.
