Formally known as The Rainboom Heard Around the World.

Twilight witnessed something as a filly. Something that changed her life, and eventually led to the strong friendships she has now forged. A sonic rainboom. But due to a mistake she made, Twilight can't remember it, nor does she know it ever existed. On the other hand, Rainbow Dash's life was thrown into turmoil soon after the sonic rainboom. And although she has mostly recovered now, the painful memories continue to lie just below the surface.

It's now the day of the Best Young Flyers competition. What's the worst that could possibly happen?

Rainbow Dash. Best flyer in Equestria, 20% cooler and the most awesome mare in Ponyville.

...But none of those traits can win over the heart of a local librarian...

This is one of the hardest challenges she faced so far...

Thanks to the amazing Cynical for the edits.

Rainbow Dash was the greatest flier in all of Equestria—or, at least, she was until she lost her wing. Luckily though, she quickly learned that flying wasn't the only thing that could bring her happiness and comfort.

Thanks to the amazing Cynical and bats for the edits.

Danny Fenton was a normal boy, but when his DNA is fused with ectoplasm, he is turned into a half boy/half ghost hybrid. What does he have to thank for that? The Ghost Portal his ghost-busting parents had created, which they had originally deemed a failure.

Danny had kept his secret for a little while from everyone except his best friends, Tucker Foley, a tech-nerd with a passion for meat, and Samantha Manson, a gothic girl who happens to be a hardcore vegetarian. He's been keeping the world safe since from ghosts hell-bent on wreaking havoc on the world under the alias of "Danny Phantom".

He's had his share of fights, but for the most part, life was turning out...alright, albeit repetitive.

However, one day, the Ghost Portal malfunctions, and instead of bringing them into the Ghost World, Danny, along with his two best friends, are transported into the distant land of Equestria with seemingly no way out.

Will Danny, Sam, and Tucker find a way to get back home? Or will they be stuck in Equestria forever?

Somehow Wheatley manages to come down from space and land in the strange and brightly-colored world of Equestria. He has no idea what happened, but his plans for dumbing everything down has yet to come to mind. He is picked up by Twilight and her plans for Wheatley are much, much different. Of course, after being turned into one of them, they slowly work him into being used to a body that's not his, and far from being GLaDOS.

Rainbow Dash learns responsibility the hard way after one night with Soarin' changes her life forever.

An ongoing series of slice-of-life snapshots, family friendly - or rather, clop-free.

Velocity - Rainbow Dash is never late. Today she's very late, in a way she never expected.

Home Away - Dash takes flight with the one pony who means means more to her than any other.

Skywriting - Sometimes you just can't speak all the words you need to say, and a letter is all you can manage.

We Few, We Happy Few - Don't ever tell this filly what she can and can't be.

Somewhere to Be - A storm rolls out of the Everfree on Dash's day off. She's got a game to get to, and there's no way this'll slow her down!

All chapters originally written as separate entries for flash-fic blog Thirty Minute Ponies (TMP). I highly recommend a visit to TMP if you're looking for some of the best 1000-word gems in pony fiction. Many thanks to TMP for inspiring me to write!

NOTE: Not related to the Luna's Librarian / Rustic & Romantic / If the Flight Suit Fits continuity. Originally this was an Alternate Universe fork from Egghead and Featherbrain, but is now a separate story entirely.

My life in Hollow Shades wasn't too bad, but I wanted to start a new life somewhere else, so one day I packed my things and moved to a town called Ponyville. A place where I could start a new life, make some friends and get a job. What I never expected was to find the mare of my dreams...

Now in TvTropes.

The leader of a successful rock band in Equestria has everything he could want- the money, the fame, the power, the fans. But, despite having the lifestyle of his dreams, something is strangely amiss; when he's offstage, he feels empty inside, and he's not sure if this lifestyle can fill the void... until he meets a cyan pegasus with a multi-colored mane.
