Guys. You are talking about fan scenarios meant to take advantage of the character development offered by the show to not have to create their own characters which they would have to develop to create an enticing story. Specifically, the fanfics described here take advantage of the innocence implied by the origin of these characters and then breaking said innocence. This is the slapstick of fanfiction. The only thing worse would be actual slapstick fanfiction,
I tried reading it but knowing what it was about made it hard for me to finish it. I just couldn't stand the thought of someone being mutilated as they begged for their life. Yeah, it's about friggin' ponies but stuff like that can still happen. Stories and movies like that just kind of mess with me.
