Here is my headcanon for the proxies in my Creepypasta/Slenderverse/SCPFoundation/Horror universe "Your Darkest Fears".
Note: I just want to remind people that what you see here only applies to MY universe. This is just how I see the proxies in my universe. Please, don't shove other headcanons down my throat. I just want to be faraway from other universes and to just have fun. I hope you understand. If you like my headcanon, I appreciates the likes.
