I just read a few scary MLP ファン fiction. I have decided to write my own. Any ideas on who and what it should be about

(Oh dear Celestia...)
Twilight ponynapping the mane 6, cutting off their skin. Making fake ponies of them to be better フレンズ after they had a bad fight. Then using the new mane 6 to every night kill a ポニー (in a gorey way) from Ponyville and so on.

Do a black humor story. Sombras ロスト episode. I have so many ideas, but no plot

... O_o Emmy... あなた should be a ファン fic writer, I 愛 that idea!

あなた want an idea for a scary story? Like a creepypasta?

Well, あなた could always write a story based on "Luna Game" または a sequel または prequel to "The Story of the Blanks."

Twilight could be interesting. I can see her going insane like in Lesson Zero, only this time X10.
または maybe Fluttershy, it could have something to do with her animals.
