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.

Celestia decides that Big Mac's barn is an excellent place to sneak off to, to take naps on her days off.
Big Mac decides that Celestia is a welcome guest.
Neither Princess nor farmer ever speak to one another, but the silence sings between them.

Celestia likes her routine. Tax reforms, grants, laws and construction projects are all a princess needs to be content.

It's just her luck that for Pinkie Pie, "content" is not nearly enough.

Twilight and Spike grew up and did everything together since forever. But following the events of Magical Mystery Cure, Twilight is now a princess. She grew up first. Spike realizes he needs to catch up, and so makes a choice to do the same.

All the while, there is a secret, one that involves Princess Celestia, our favorite little dragon, and a certain sense of heritage.

When Rarity writes to Princess Celestia inquiring after how dragons age, she gets a plea for help in reply. A war is brewing, and Princess Celestia thinks Rarity's the one to stop it. Now, still completely uncertain what her feelings for Spike are or if they're even plausible, she's off to meet with his distant relatives to negotiate a truce between the dragons and the sea serpents before the world gets caught up in their destructive clash.

(Post-Mass Effect 3)(FemShep)
When the Reapers were defeated, the galaxy believed that Shepard and Anderson were both lost in the final battle. However, the two long-time friends were also known for not letting death stand in their way.

Waking up, in the middle of a desert, on an uncharted planet they both embark on their strangest mission yet. Attempting to find their way back to the Human Alliance, a place called Canterlot may hold the answers they seek. But first, they had to get there while trying not to draw too much attention to themselves.

Too bad for Anderson since massive explosions and collateral damage followed Shepard wherever she went, without fail.

Crossover of My Little Pony and Mass Effect.
