Dubbed Mr. Fly and alternately known as Chablis or Chabris, this mutated entity lurks within the Old School Building. First appearing as a spectral presence haunting the school’s bathrooms, it manifests as a diminutive fly-like creature sprouting writhing tendrils. Though no larger than a common housefly, it wields unnerving physical strength far exceeding its size. Its lethal touch delivers instant death, while its capacity to warp the environment allows indirect assaults—toppling structures, dislodging debris, or triggering collapses without direct contact.

Born from an ordinary insect twisted by unknown forces, it evolves into a terror so potent it evokes dread even among fellow supernatural entities. Driven by primal urges to destroy and consume, it particularly savors the taste of human flesh. This ravenous predator becomes a persistent thorn in the protagonists’ mission, deliberately sabotaging their efforts through calculated ambushes and manufactured environmental dangers.

As a secondary antagonist, it heightens narrative tension through erratic violence and displays of otherworldly power. Visualized through body horror elements, its form blends grotesque mutations—bulging compound eyes, distorted limbs—with disturbingly recognizable insectile features. Its origins remain shrouded in mystery, existing solely as an apex predator within the school’s concealed supernatural hierarchy. The creature’s documented existence remains confined to the primary film’s events.
