(Grimdark warning. This roleplay group is exceptionally graphic and those who don't enjoy seeing darker sides of the series need to just....scoot now.)

First off, I'm not taking credit for anything. This is all based on a roleplay, which is absed on a parody, which is based on characters creaded and owned by Hasbro and Lauren Faust.

That being said, those familar with the spoof series Friendship is Witchcraft may remember Cult Leader Fluttershy. Well, someone roleplays as her for the Chaos is Magic group, only she's a tad darker than in the parody. Her goals remain the same; resurrect Lord Smooze and bring about the end of the world. She's managed to remain a reoccurring opponent for the Mane Six from the Equestria we all know, and the Smooze has proven to live up to its title of being nearly unstoppable for even causing Discord trouble.

Currently, the Smooze has to regenerate after it was separated from its cult by Twilight Sparkle, but Fluttershy managed to keep a portion of it and has allowed it to grow by consuming parts of her, to the point where she is reliant on it to stay alive. When it has devoured enough, it will return and bring about the "Smoozepocalypse" she is always talking about in the parody.

She has her own faction in the roleplay and is actually not associated with Discord or any other antagonist in any way aside from Researcher Twilight Sparkle (who is based on the tumblr) and has aided Fluttershy by modifying the Smooze and furthering its nigh invincibility for the sake of science.

Her battle theme is "At the Very Beginning" from the Rebuild of Evangelion series. A befitting title since the Smooze is an enemy that dates back to the original My Little Pony cartoon. So in a sense, they're fighting a battle that began at the very beginning of the franchise.

Lyrics:
At the very beginning, we were created
To live together but soon, we hated
In greed and selfishness we could never prosper
Created enemies against God's will

Almost fits the storyline, if you consider that Queen Faust is God in the storyline, and the living together but becoming hateful is just what Discord and Smooze-ridden Fluttershy has done to Equestria. Food for thought.
