Intro. The Rot is a My Little Pony horror alternate universe (AU) known for its dark, infection-themed storytelling.
Early Stage: Mild flu-like or cold symptoms, sneezing, coughing, congestion, and subtle behavioral changes such as confusion, insomnia, or irritability.
Middle Stage: Progressive physical decay, including rotting flesh, eye and mouth corruption, loss of hair or feathers, extreme thirst or hunger, and growing aggression
. Behavioral changes often include insanity, incoherent speech, and even cannibalistic urges.
Late/Final Stage: Severe deformities such as extra mouths or eyes, skeletal exposure, tentacle or root-like growths, fungal or rainbow-colored proliferation across the body, and in some cases full immobilization or rooting to the ground (e.g., Swamp Fever AU) or vampire-like transformations (My Little Bats AU). Death is typical, though some AUs like the Smile Virus suggest the possibility of a flawed cure that leaves permanent mutations.
