Flash Sentry has come to accept that in a world now full of magic, someone like him is nothing more than a side character despite how much they want to help. He's sent to live a life of boring mediocrity, until one unexpectedly strange day. From out of nowhere, a pod comes crashing down to earth. And inside is a device that will change Flash's life forever. The Omnitrix.

-In Loving Memory of Kevin Conroy-

The Riddler has gone into hiding somewhere in Canterlot City, working on some type of new technology that could be dangerous in the wrong hands. The Dark Knight: Batman, has traveled to Canterlot City to stop Riddler before he has the chance to use this tech for his own gain.

Things are made complicated when Princess Twilight comes through the portal to visit Sunset Shimmer and her friends for the weekend. The involvement of these High Schoolers makes the situation a whole lot worse.

Batman, against his better judgement, must work with The Equestria Girls to stop Riddler and save not only Canterlot City, but Gotham as well. But that may be difficult since Vengeance and Friendship don’t exactly make a good combination.

The superhero Ben Tennyson was chilling at his home until he was called to Plumber HQ by his grandfather Max. When he gets there, he is told that Aggregor and some other enemies of Tennyson's have broken out of the Null Void and vanished into another dimension. Ben is instructed to go into the new world and find them. When he gets to this new dimension, he finds himself in a new form....a Pony!

In this new form, he will search the land of Equestria to find his foes. And with the help of Twilight Sparkle and her friends, what could possibly go wrong?

When a pirate named Captain Jack Silver steals the Elements of Harmony and kidnaps the Cutie Mark Crusaders, it's up to Twilight and the rest of the Mane Six who now must take to the high seas in order to get them back. When the Mane Six finally find them, they all soon find themselves joining Jack and his crew on a swashbuckling adventure filled with challenging spirits, terrible storms and demonic pirates, all of which act as obstacles that stand in their way of finding the SEVENTH Element of Harmony.

when Sunset Shimmer applies for a job as a Night Guard for the Canterlot Mall, she soon discovers tiny robots in disguise live inside the mall, hiding as anything, objects, technology, even food! Now she becomes friends with a group known as The Lost Bots and helps to keep the Botbots existence a secret.

An entry in the Bloodlines Continuity

It isn't always easy putting up with family. Some of them are embarrassing, some try to tell you how to run your life, and some try to invade the capital city of Equestria. Queen Chrysalis may be gone, but for the owner and employees of the Metamorphosis spa and massage parlor, their work has just begun.

In the meantime, Chrysalis is in for a lot of angry letters...

Just as earth ponies, pegasi, and unicorns have mastered their special magic, tragedy strikes at the Crystal Bright House. The Unity Crystal has been stolen by a mysterious dark alicorn!

What most concerns Sunny Starscout and friends, is what exactly this mysterious alicorn plans on doing with the Unity Crystal. Can Sunny Starscout, Hitch Trailblazer, Izzy Moonbow, Zipp Storm, and Pipp Petals bring the evil alicorn Opaline to justice before the worst comes to fruition?

After an urgent summon from Fancy Pants, both Celestia and Luna attend Day court. However, a new precedent is set when Fancy Pants presents a male alicorn to the two princessess, one he found dumpster diving behind his house.

Not much else to say without spoiling a lot of the story. Just jump in and heave a read!

It all comes to a head...will the elements of harmony be able to stop Grogar and his associates? It'll be quite the battle, and it won't be easy...
This is a slightly more logical version of how the show ended, replacing unnecessary dead-end plot threads like the Windigoes and Twilight running off to the Crystal Empire with focusing on intelligent character choices and more emotion, while also trying to be a little more varied between full-on humor and seriousness.

Gather 'round, you ponies fair,
And here the tale of how one little mare
Came across a rare find
That had placed her quaint home in the biggest bind.

Avarice is stranger to nopony at all
Not even Rarity can avoid its call
And the worst part is that anything goes
Which could only fill Ponyville with woes.

Now this is a story all about how
Their lives get flipped turned upside-down
And I'd like to take a minute, just sit right there
As I tell you how this is the fault of one mare...
