After some time of turning over a new leaf, Sunset was happy with her life. She gained new friends, slowly winning over the students at CHS and became the protector of the human world alongside her friends against any rouge magic and creatures. She wanted to give back to everyone by becoming the head director of the Christmas party and Toys for Kids Festival at the school on Christmas Eve.

But when the events of the party and festival went wrong due to her past, Sunset was down on her dumps after she was blamed for the disaster and felt like she had ruined her friends lives because of her. Just when she was about to give up on everything, a mysterious teenaged girl, who claimed to be her guardian angel, showed Sunset what the world and her friends would be like without her.

This is an Equestria Girls take of an ever so beloved classic Christmas film, It's a Wonderful Life!

FEATURED: 3/20/20 - Wow! Thank you all so much!

Raven of the Teen Titans has long been a closet pegasister. She was introduced to Friendship is Magic by Beast Boy and Starfire and - although she is loathe to admit it - she enjoyed it. She especially identified with the character of Twilight Sparkle. What with Twilight's enjoyment of reading, talent in magic, and unexpected but life changing friendships, it felt like Raven's own life mirrored and sugarcoated onto a world of pastel colored ponies. Even Twilight's friends reminded Raven of her own to a certain extent.
When she wakes up one morning in Twilight Sparkle's body with no idea how this happened or how to fix it, she begins to think she identified with her a little too well.
Now trapped in the plot of the series from the beginning, she has to find away to fix this, find out what happened to the real Twilight, and at the same time save all of Equestria. At least she has some friends to help, right?

Crossover idea inspired by the fact that these two characters share the same voice actor, Tara Strong. Originally, it was just an idea I played with for fun, but I have a serious - and frightening - plot for it. Dark for later chapters.

Being a unicorn pony, a high school student, a magical girl that fights with the power of friendship, and an artist, Sunset Shimmer thought she was ready for anything the world could throw at her.

What she never expected was to be called by the principal, saying that her mother was looking for her.

Written for A Most Delightful Ponidox.

Not even a day and it already got featured! Hurray!

Note: If you're a reader of my story, Seeking My Purpose In The World, consider this an alternate timeline where Sunset went through the mirror to the human world.
If you haven't read the story, don't worry it's not necessary

Following Twilight's coronation, Starlight suddenly finds herself owner of the Friendship Castle, and has to figure out what that means, for herself and her friends. And then an unusual changeling comes knocking at her door...

This story is a sequel to My Little Universe: Season 8

The Elements of Harmony and the Crystal Gems had come a very long way. Earth: a colony planet for a renegade Diamond, now in watch and care by a 16 year old Human boy and his team of Polymorphic Sentient Rocks. And Equus: a planet right from a storybook in charge by the Princess of the Sun, now in watch by her most faithful student along with her closest friends of all three Races. A princess of Friendship, and a Prodigy of Care.

They've done so much to get to this point, and they're so close to being finished. Corruption still needs to be healed, old quarrels still need to be mended, and still looming is an army that is bent on ruining everything they've built up to this point. Can they make it to that Happily Ever After?

This story is a sequel to My Little Universe: Supernova

The Everstorm had left it's mark on history once again. In the wake of the fallout, and perhaps afterwards, the worlds we know had been given a whole new era to deal with. And time, as we all know, doesn't stop for anypony, and new things can happen all the time. And in these changes, a whole new princess of Equestria, Twilight Sparkle, has now been passed as the true successor to Celestia. Not to mention too, about the big events following Steven Universe's true identity as a noble and royal member of the diamond Authority! Will this make life easier for them?
Well, every new change isn't without its catch, and new changes are also being put underway: A visit back home reveals old customs far too enforced, and new creatures are guaranteed to make things just a little bit more bothersome. You know, as always with life. It's time to test the durability of the Harmony Gems, as they stand up to the tasks ahead in loyalty, and adapting.

Harmony Gems unite!

This story is a sequel to Tantabus Communication Protocol

What started with laziness and a tiny slip-up in arcane intelligence creation has blossomed into its own being. With Luna's blessing, the second Tantabus is free to flit around the dreamscape as it pleases, unburdened by oversight. And what pleases it is making good dreams. Who couldn't be happy by making others happy?

As the Tantabus settles into its life, its horizons keep expanding, forever revealing more of the world and of ponies. There's always new things to learn. New dreams to spice up. New nightmares to beat down. New ponies to help. New ponies to annoy.

Don't tell Luna about that last part.
