Gender: Unknown / Class: Keter / Height: 196cm / Weight: 44kg A gaunt, white body lacking all sensory organs except for a mouth. The mouth hangs wide open, revealing 21 sharp teeth. Inside the mouth is a glowing blue eye, and as muscles stretch, the eye may protrude outside the mouth. The limbs are approximately twice the length of the torso, and while it has only 3 to 4 fingers, they are long and sharp. It has no feet; the ends of its legs are long and pointed. The blue eye generates micro-black holes, emitting immense radiation in the process. It is weak to high heat, high humidity, and intense flashing lights.

Male / Class: Euclid / Height: 190cm / Weight: 95.3kg Appears to wear a black hooded robe and a plague doctor's beak mask, but these garments and the mask are actually thick skin. The internal skeletal structure is very similar to a human's. He speaks with a highly intelligent and calm male voice with a medieval French accent. He claims that humans are infected with a 'Pestilence' that only he can see, and he possesses a fanatical sense of duty to save humanity. Any living organism he touches dies instantly (excluding other SCPs).

Genderless / Class: Euclid / Height: 238cm / Weight: ??? Possesses an extremely gaunt physique that appears severely malnourished. Lacking pigment, its eyes and body are a pale white. Its jaw can stretch up to four times the size of a normal human's. Surprisingly, its body is as durable as adamantium. Normally docile, it will kill anything that views its face (excluding other SCPs). It can run at speeds ranging from 35 km/h to over 100 km/h. It is also an extremely fast swimmer.

Male / Class: Keter / Height: Approx. 182cm / Weight: ??? Appears as an elderly man but is in an advanced state of decomposition. He wears a grotesque and unsettling smile and is covered in a black mucus. Due to the decay, pieces of flesh occasionally slough off. He uses a powerful acid to rust or corrode everything (including living organisms) and can phase through walls via noclip. He is known to pull prey into his personal 'pocket dimension'.

Genderless / Class: Keter / Height: 8.84m / Weight: Several tons Consists entirely of a vast number of white wings. Prying through the wings reveals a 6-meter humanoid figure curled in a fetal position inside. It feeds on sound and has a fanatical preference for rhythmic music or bells. It exists in a state of eerie silence, producing no sound of its own. If someone approaches, hidden wings lash out like snakes to drag them inside, where it injects hellish neurotoxins and potent stimulants to ensure the victim screams without dying. Consequently, the entity grows while the host continues to scream until they die of shock.
