So I have been looking around for dark fics and I found one mlp character who has been in plenty of mature stories but not in any grimdark one. I am talking about Fleur de lis (the pony in the image below).

Sadly if you try to look her up in anything dark all you get is either her being in a war story or clopfics. I think she deserves more. I think she could be an excellent grimdark villain or heroine.

I hope this gives you guys some good ideas for your stories.
