Some societies worshipped masters of thunder, who wielded mighty hammers. Some societies worshipped those who had the head of a crocodile. And then, there were those deities that were a bit more, well, colourful. A bit more fun-loving. A bit unpredictable. But they were caring also, and for them, the world was big, beautiful and was to be handled with tremendous responsibility.

...Oh, and it was also a massive playground for them to do pretty much whatever they wanted. But hey, work hard and play hard, right?

This is a parody of avatar the last airbender, using ponies! Read as the avatar, Twilight Sparkle, travels on a journey to stop the water nation's war against the world.

Twilight was always fated to be the savior of Equestria, along with her friends. But fate can be so easily altered. What happens in one alternate realm when instead of marrying a unicorn, Twilight's mother had instead married an earth pony, resulting in her daughter being hornless? Without her magic, Twilight's future and destiny are far less certain, as is the destiny of all of Equestria.

However, destiny is not so easily set off course. When the princess of the night returns, can one little earth pony hope to be the one to help her damaged heart?

This story is a sequel to Dexter's Lab: Equestria

He was so sure Nightmare Moon wasn't real. He was so sure all the stories about Nightmare Moon were merely fabrications meant to induce fear in the ponies of Equestria, and insure their loyalty to the alicorns upon the throne. In fact, he was so sure Nightmare Moon didn't exist, he built a time machine to go back 1000 years and prove it.

Needless to say, this time-travelling colt genius bit off more than he could chew.

Now the 8-yr-old must survive the chaos of Nightmare Moon's uprising, forging unexpected alliances while learning to trust in the word of others. But unfortunately for him, Nightmare Moon isn't the only surprise in store for this colt.

This fic is a side-story to Dexter's Lab: Equestria. As requested by you readers, this story will be expand upon darker themes surrounding Luna's original descent into Nightmare Moon and the following events. - But expect a twist or two. This story was made separate to Dexter's Lab: Equestria because of it's darker themes and atmosphere. Reading of Dexter's Lab: Equestria (to chapter 11) is not required to enjoy this story, however it is strongly recommended as it will explain a lot (especially if you've never seen the Dexter's Lab TV show.)

Deciding to pay her old friend, Princess Twilight, a visit, Sunset Shimmer returns to find Equestria no longer the “friendly” kingdom she remembered.

Looking for answers, she joins a rag tag team of young ponies, who hope to make Equestria the kingdom it once was.

Based on the movie: Sonic the Hedgehog, but with some changes.

After fleeing to planet Earth, Sonic the Hedgehog has been secretly living in Canterlot City as his new home for the past decade along with his incredible power of super speed. Things went well for him, until he accidentally knocks out the power grid, getting the attention of the military organization, G.U.N., along with the evil genius, Dr. Robotnik.

Meanwhile, the Equestria Girls was preparing for their upcoming graduation, leaving Sunset Shimmer unsure of her future. When the power grid near their school was knocked down, CHS was in suspicion by G.U.N., sending in a special agent to investigate as a result.

When the two groups meet up due to circumstances, Sonic and The Equestria Girls must team up to retrieve Sonic's rings and stop Robotnik from using Sonic's power for world domination while fleeing from the government.

Sequel: Left Behind: Sunny Disposition
Apparently it was scouted and is on EqD too

Nightmare Moon was meant to be released after a thousand years. A momentous occasion for her but terrifying for all the ponies on her day of freedom. She would get revenge on her sister and cover the world in darkness and shape everything to fit it.

That was the plan, at least. Instead, something went awry with the spell and she wasn't released when she was supposed to be. The mare-in-the-moon is brought into a world with stagnated technology, giant cities, and no sign of her sister or any of the other immortals. In fact, ponies don't seem terrified of her at all, and the stay within the core of her powers infused and changed the alicorn's body drastically.

The alicorn had no obstacles left! But...she was also a relic of the past. A past everyone seemed to have forgotten. A past she could no longer look upon.

Big thanks to Kryostase for helping spot errors I've missed.

The day of Princess Twilight Sparkle's coronation, her ascension to ruler of all Equestria, has arrived! But what was meant to be a beautiful day of celebration turns into the greatest disaster in Equestrian history. Chrysalis, Tirek, Cozy Glow and the shadow of a past enemy have been hard at work turning pony against pony and studying the ultimate power of Grogar's Bewitching Bell. Grogar himself has acquired an artifact once thought to be kept away from the wrong hands (or hooves) forever, hoping to use it for an important purpose, but is blissfully unaware of the evil tetrad's deception. Or so they think...

With the Horses of the Apocalypse attacking everywhere, the world's mightiest defenders, including the Council of Friendship, will have to step up and protect the people. Will their rainbow lasers light the sky and win the battle like they always have, or will the diplomacy of their non-combatant allies be the key to restoring unity to the broken equine societies and saving all creaturekind?

2024 EDIT: The TV Tropes page!

Author's note: I know this has been done before, and i'm super late to doing it, but it took me a while to realize what I actually thought of the final two-part episode, and you can probably tell the conclusion I drew by the fact this rewrite exists. This envisions what the 24th and 25th episodes of Season 9 (The Ending of the End) would be if they were instead a four-part, feature-length, apocalyptic epic. Imagine an alternate universe where Season 9 was still 26 episodes long, but two episodes had to go (i'd personally axe 15 and 16, sorry fans of those) to make room for extra parts of the finale. It also takes everything that has happened in the season as canon, but with two differences.

1: I treat Grogar as if he was the genuine article, because in my opinion, if they were going to put him in G4 at all, they really should've made the effort to utilize the guy somehow beyond a powerful item. It was his first appearance in 3 decades, he was a popular G1 villain among fans, and the Season 9 premiere introduced him as an interesting expansion on one of the show's longest established elements. Also, with the way the show was written, changing him to the real thing feels quite easy.

2: I have slightly rewritten the past events involving the villains to add my own little touch to the story. Something that gives a little retroactive significance to both the events of the 13th episode of Season 8 and a fanservice-y thing they did in the 8th episode of Season 9. Before you get started, let me tell you that it's not going to be what you're expecting.

Just to be clear, despite my opinion on the official version, this has not been made with any ill will towards Big Jim Miller, Nicole Dubuc, Michael Vogel or any of the storyboard artists and animators that put the finale together over at WildBrain (formerly DHX Media). This is just something I did to pay tribute to a series i've loved for a long time, do a little writing exercise, show what I personally would've liked to see in the finale, and of course, have some fun. I know a lot of people love the original episode, and I don't intend for this rewrite to replace it. It can never be replaced, or erased, or redone. However, I do hope it can be a fine alternative for both fans and non-fans of the version we got on television. I'd even like to respect what the creators were going for, but tweak their ideas a bit (because there are things I enjoy).

One last thing: I want to highlight StarlightisVERYcute and SuperPinkBrony12 for inspiring me to do this. They've done exceptional rewrite jobs that I highly recommend you give a look.
