dont ask why this guy reminds you like john doe from forsaken- This guy just appears near the front door of the current room for a split second before despawning, this guy is basically docile, so if you encounter this guy, you can just walk up to the next room cuz this guy only was added to scare players like you. Image origin: Nothing, Just nothing, It's literally made out of scratch. Sound origin: Another static noise which is used for the original B-60 and the IR E-60.
Fun fact: this entity actually used to be an person, but he somewhat died to A-60, causing him to act and look like this, one of the proofs are in the title / his name. This guy has a chance to spawn after A-000 if your wondering. But its an EXTREMELY RARE CHANCE to encounter him at the lobby. Another fun fact, before he looked like this, his dead body might look like this: https://scratch.mit.edu/projects/1090270463/ (credits to @peter_colorbox)
