Equestria is growing, and magical savant Twilight Sparkle is disgusted by the crime and corruption this change has brought. Her life is changed forever when she discovers the Death Note, a notebook with inexplicable and deadly powers. She uses this book to pass judgement on those she deems unworthy of life, aiming to create a perfect world free of crime. But when the two Princesses put their best pony on the case, a mysterious detective known only as L, a psychological game of cat and mouse erupts between the two.

Red Team had been given an assignment. It wasn't the usual sort of assignment. They were assigned to defend their base 'until further notice'...and then never received notice. All announcements sounded pre-recorded, and enemy assaults were few and far between. The enforced inactivity was slowly fraying the bonds of the team...

...until something unexpected arrived. A tiny creature appears one day in their fortress, in need of compassion and care. Somehow, she finds that in this group of strange individuals, as she becomes their baby.

Crossover with Team Fortress 2.
Part of the PWNY-verse.

Kuzan had no idea where he is, how he got here, or any idea on how to return home. All he remembered was taking a nap on Camel and waking up in the middle of a forest when he was pretty sure he was in the middle of the sea.

Well the good news is that he found a native, hopefully one that will tell him where he's at. The bad news? Neither of them can understand each other due to a language barrier, not to mention that said native is a blue unicorn that he saved from death... Actually, compare to the things he have seen in life, that doesn't even phase him.

Still he has to find a way home... after a quick nap.

After discovering that Cadence is not who she appears to be, Twilight is sent to another world entirely by the disguised Changeling Queen to avoid her plan being disrupted.
When Twilight lands, she discovers that not only have Spike, Owlowiscious and Peewee followed her, but that they've arrived in a world where the main sentient species is human.
There's still a place where they teach magic, though.
Crossover with Harry Potter. Twilight will be effectively taking the role of Hermione.

I've marked this story as cancelled to reflect the unlikelihood of it continuing. If I do come back to it I'll revert that.

Applejack is known for a lot of things: being honest, being strong, loving her family... apples. But the thing she's most known for is having a really incredible set of eyebrows. It's for this reason that Celestia has seen fit to bestow upon Applejack that highest of honors. She's going to make her a princess... of eyebrows.

It takes less than 24 hours before Ponyville is literally on fire.

You can thank the last Seattle's Angels Podcast this time.

Usually when a file says that one of the elements have died, the devil usually thinks its just another pony (or other creature) that is trying to get to heaven. So he burns the file and sends the so called element bearer to his place.
This time its different. Very different.

This used to be a paradise, now it's become something else in its entirety. Soaked Bandage, an off white earth pony stallion wakes up to find that everything he knew has changed, and not for the better. This land has become estranged as a rather curious and deadly disease has spread throughout the land. One that so far no magic or science has been able to cure. The only ones who occupy the land now are the survivors and the dead.
This story is based off of a combination of the world of My little Pony: Friendship is Magic, and the graphic novels/ comics of The Walking Dead.
I own neither and this is purely a work of the imagination.

About a month before the Season 4 finale, Applejack challenges Discord to a day of doing physical work around the farm. It goes about as well as you'd expect.

This whole thing started as a silly little RP me and my good chum Castoro Chiaro started one day, which slowly grew into a rather massive story. She wrote all of Discord's parts, and I took control of Applejack. I hope you all like it!

Did the ponies really forgive Discord, or had they just said so?

Of course they did, but Discord has his doubts. How could they forgive him like that, after all of the awful things he did to them? To find answers, Discord seeks out one that he'd rather not seek out: Twilight Sparkle.

After Rainbow Dash sincerely apologizes to the Spirit of Chaos, they start to bond as good friends. However, after a long chat, Rainbow starts to feel an unusual pain in her heart she can't fight. Who knew how much she actually could feel for somepony- or some draconequus- she'd used to hate?
