Las Plagas refers to a fictional parasitic organism featured in the Resident Evil video game series. These parasites infect hosts, leading to violent behavior and loss of control. They are primarily associated with the Los Illuminados cult in the game, which uses them to create powerful bio-organic weapons. The most notable type of Las Plagas is the Plaga, which can be transmitted through bites or other forms of contact. Infected individuals, known as Ganados, exhibit enhanced strength and agility, making them formidable enemies. The presence of Las Plagas adds a layer of horror and challenge to the gameplay experience.
