Percy Jackson and Annabeth Chase have gone through a lot. They fought the Minotaur, Medusa, a Manticore, the Chimera, Kronos, and even Arachne, the Spider Queen. It was during this last fight that they recovered the Athena Parthenos, a sacred statue that would help secure the demigods' victory over Gaea and the Giants, but the unexpected happened: the floor gave away, and the pair fell all the way down to Tartarus. The first thing they noticed, was that a large mirror, that no monster would approach, not even for some tasty demigod blood. They were trapped, and the only way to save themselves, was through that mirror. What was on the other side, however, was even wilder than they ever thought possible.

(Added romance tag and made story "Teen" for planning on future chapters, and romance mostly in post-story Extras section.)

(Being a big Percy Jackson & The Olympians fan, I couldn't help but notice that Tartarus existed in Equestria, according to Twilight. This story recounts the events of Percy and Annabeth's journey into the other side of the Pit, and beyond.)

The Sky Army leaders have a talent for getting into trouble,but now they've really done it. An accident leaves them stuck in a world of pastel colored equines, and they find that the only way out is through an ancient ponytale that no one can even confirm is true. Reluctantly, they agree to stay and see what will happen, and new friendships are born. But soon, a terrible accident occurs, and the group finds themselves in the heart of the blame. Taking a path that no one could have predicted, they discover a traitor, solve an ancient conflict, and go on a journey that will take them all across Equestria-and maybe even the beyond.

Phineas and Ferb create a new invention: A portal to travel to another dimension. Little did they know that it was a world full of ponies...with happy lives and sunshine almost everyday. They meet the mane six and explore Equestria, not realizing their portal has been destroyed. Will they ever return home?

I do not own My Little Pony: Friendship is Magic or Phineas and Ferb...I wish I did though.

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.

When Wreck-it-Ralph finds a villain character who seems to have gone Turbo, he finds more than a handful in the handful sized sprite.
For one thing, she has no idea what game she comes from.
For another, her code seems completely foreign to the Arcade.
For a third...she's absolutely adorable.
Having only just finished cleaning up after King Candy's mess, this little Nightmare could be a problem...or the greatest blessing Ralph has ever received.
And shadows from the past move behind the scenes...

It is recommended you read this story in one of the Dark formats in order to better distinguish the colored text of the 'other voices'.

Yup!
Oh, and for those who don't know yet, this story is part of the PWNY-verse. It's not all about us - even if it should be - but you'll probably enjoy it to-Oh, stop making me a shill already!

Oh, by the way, it's recommended you read this story in Dark or Ultra Dark. Some of the colored text doesn't show up clearly otherwise. Not necessary, but just a suggestion.

After a month of being missing after a magical mishap, Spike has returned to Ponyville. However, he's not the adorable baby dragon everyone remembers.

Now a well fleshed out drake, and garbed in armor the likes of which ponies have never seen, he walks with caution, grace, and absolute confidence. His eyes show wisdom beyond his years, but he has trouble remembering details about his friends. But he returned with a purpose.

He also didn't return alone.

One thing is certain though...he has a story to tell. That is this story.

MLP/Metroid crossover.

Edit: Now with cover art by DavieRocket.

Kratos...the Ghost of Sparta...

Under the domination of Ares, the God of War, he committed horrid atrocities, including the slaughter of his own wife and daughter...

Visions of what he had done would haunt him all his days...until it brought his days - and his world - to an end...

At least, that's what the fates have decreed await him and Olympus.

But Fate changes sometimes. Some things can't be predicted, even by gods. And this time around, one of those things has found her way to Kratos at the very beginning of his Nightmares.
