Stan

Stan is a hallucination frequently seen by those diagnosed with schizophrenia. He was also claimed to be removed in the April Fools 2021 Update, though it is unknown whether he has actually ever existed.

Behavior
Stan will appear at night, whether it be 0:00 AM or 3:00 AM, it will stare at you for a short time, it will be disappeared for a half minute. However, it doesn't kill you.

Stan can uncommonly be found on Earthlike, Some Starters get afraid as Stan stares at them and stalk them. Stan can very rarely be found on Terra, Tundra, Forest, Exotic, Desert, Barren and Ocean (sometimes). Stan cannot appear on Gas Giant, Space, and Non-Oxygen Planets.

Description
Patients who claim to have seen Stan often describe him as a black humanoid figure with glowing eyes. He is frequently compared to the creature in the Roblox game "Identity Fraud", which seems to accurately match the description by the patients.
