To change the future of Equestria

“What do you mean you're gonna kill him?!” yelled Rainbow Dash while they began to go into the Everfree Forest.

“This is, you can't be, darling, you can't be our Fluttershy.” exclaimed Rarity.

“She's being honest.” said AppleJack sternly. “I can tell.”

“But, but...” stuttered Rainbow Dash till the Future Fluttershy interrupted her.

“It's okay AppleJack, except for my name, I'm not really Fluttershy anymore anyways.”

“Why? What happened to you, er, me?” questioned Present Fluttershy.

“Well, Dark Eater successfully obtained the full power of the Tree of Harmony and the Crystal Heart of the Crystal Empire with the Gem of Keys. He then killed everyone here except me and Twilight.”

The Mane Six and Celestia all gasped at the same time. Then Future Fluttershy continued.

“The next five years were hell, granted not everyone died here immediately but over those five years, only me and Twilight were left. Twilight successfully found a new method of time travel with the help of Sunset Shimmer and Trixie Lulamoon.”

“Sunset Shimmer and Trixie helped me do this?” asked Twilight.

“Yeah, when we get to Dark Eater, Sunset Shimmer will be there with him.”

“Why, why is Sunset with her?” asked Celestia.

“He has probably already brainwashed her, Princess Celestia. We spent over two years after we saved her to put her back together.”

“So, you mean Dark Eater is from... the Equestria High world?” asked Twilight.

“Yeah.”

“But it's not another several moons before someone can go thru the mirror.”

“He found another method, he will be on his way here now.”

They then reached the Tree of Harmony but no one was there.

“Looks like we made it in time. Thank goodness.” said Future Fluttershy happily.

Meanwhile on the outskirts on the Everfree Forest...

“This must be the place.” said Dark Eater with a grin.

“Yes Master.” said Sunset in a monotone voice.

“You know, I know I hypnotized you Sunset, but you could show some more enthusiasm.”

“Sorry Master.”

“.....Ugh, Nevermind. You're no fun. Now, let's gets us some power. This is gonna fun.”

He then proceeded thru the forest and eventually got to the Tree of Harmony only to quickly stop right before getting there.

“Why are there other ponies here?” said Dark Eater silently.

“I do not know Master.” said Sunset.

“Did you warn them before I hypnotized you Sunset?” he said silently with a glare.

“No, I did not even know of your plan.”

“Oh, right, hmmmmm.... Well okay, Can you identify who's down there?”

“Yes, there are the elements of harmony down there along with Princess Celestia and a hooded pony that I do not know.”

“Celestia?! Which one is Celestia?! Wait... its that Rainbow Haired pony isn't it?!”

“Yes Master”

“That blasted hag, I can't believe it. She always tries to get in my way, no matter what alternate world it is...” said Dark Eater and then he began to sit there and think. “Now, how am I gonna win this? Maybe....No that won't work....Hmmmm......Ah that could work.”

He had Sunset take off her pack on her back and began to shuffle thru her bag, “Here we go, I'm glad I brought some gear for plan B.”

He pulled some smoke bombs out and commanded Sunset to get ready. He then threw the smoke down on the Mane Six and rushed into the Tree of Harmony. The ponies immediately started coughing and wheezing.

“What's *cough* *cough* going on?”

“He's *cough* here!”

“I *cough* can't see! *cough*”

“Sunset, put up a barrier now!”

“Yes Master.”

Dark Eater was now in front of the Tree of Harmony while a magic barrier blocked in front of the Mane Six. Then the glowing red stone on the necklace Dark Eater was wearing began to shine. “Gem of Keys! Give me the power I want!”

The gem began to shine as red energy poured out and connected to the tree. “Yes! Yes! Hahahahahahaha! Give it to me, give me everything!!!” Dark Eater said menacing with a huge grin on his face.

Then a huge fan made of magic appeared from Twilight and sent the smoke away and then they all saw what was happening. “Girls, we need to stop him now!”

Celestia, Twilight and Rarity immediately poured magic from their horns on Sunset's barrier and it began to crack. “Pour it on!”

“No! Just open a small hole!” yelled Future Fluttershy.

They quickly did and Future Fluttershy jumped thru and immediately tackled Dark Eater.

“What are you doing?!” yelled Dark Eater and then he saw what was under the hood. He then immediately shot magic at her. “How are you?” He then turn his head to the Present Fluttershy and then suddenly realized. “So that's how you knew I was coming.”

“How did you know?!” Future Fluttershy yelled.

“You being here means only one thing....heh heh heh.. HAHAHAHAHA!!!!! I won didn't I?!”

“No. You won't win today.” said Future Fluttershy and then pulled a small blade with gem on its handle from her hood and the blade was glowing. “This ends right now.”

“What is that?!” he yelled and then Future Fluttershy rammed into him before he could act. She then slammed the blade into the gem.

“Goodbye Monster!”

“What have you done?!” he yelled as the gem kept glowing brighter and brighter and then it exploded.

BOOM!!!!!

The explosion sent Sunset Shimmer, Dark Eater, and Future Fluttershy flying.

Present Fluttershy quickly went to her Future self and she saw the wounds the explosion gave her.

“Are you okay?!”

“No.... *cough* *cough* My time's up, I've lived to long anyways.”

“No! No! You can't die! You're me!” yelled Fluttershy while constantly crying.

“Fluttershy, it's okay *cough* *cough* just promise me something, never lose your kindness Fluttershy.” and then she died.

The Main Six all sat there crying as they all saw Future Fluttershy die. They then buried her by the Tree of Harmony and took Sunset Shimmer and Dark Eater to Canterlot as both were still unconscious and filled with bruises and wounds.

A Few days later....

In the hospital at Canterlot, Sunset Shimmer woke up and saw everyone there. “Princess Celestia?!” she said slowly.

“Yes, we are all here Sunset.”

“If I'm *cough* *cough* here then....oh no! Where is Dark Eater?!”

“He's in the dungeon here.”

“Oh no, no no no no no!!!!”

“What's wrong?! He was evil and we beat him. What's wrong?!” Rainbow Dash said sarcastically.

“Dark Eater lost.... I have to get back to Equestria High immediately!”

“Why?” everyone asked.

“Because, the one who wields the true Gem of Keys is going to destroy it!”
