I just had a thought for an SCP that would be kinda interesting.
What if where is a person who has no special properties, other than the ability to convince others she somehow has unexplained dangerous supernatural powers. These would constantly affect her whether she would like them to or not, and she would have no control over her power to create this effect whatsoever. So despite the fact that she's an unextraordinary human being, everyone is super afraid of her.
I'm wondering about how I might actually pull something like that off though. Either it would have to be a mental effect or things would just have to somehow line up so everyone is convince she's an SCP, perhaps through some causality or luck effect.
