MLP/Undertale crossover.
Not a PWNY-verse story.

Long ago, the Monsters and Humans fought a great war. The Monsters lost, and were sealed in the Underground. It would take the power of seven human souls to break the barrier that kept them imprisoned. They only had six. And so the Monsters waited and hoped, praying that another human would find their way to the Underground. Some thought the seventh soul would give their King the strength to break the barrier. Some dreamed of a human who would be their friend, and save them all...or had nightmares of one who would bring back the war.

...but nobody came.

...but somepony did.

Eons after the war, with no way to tell how much time had passed above, a tiny blue filly with wings and horn fell into the underground, calling for her Mama. None knew the poor creature's nature or origins...but her soul was powerful with magic, even more so than a human soul.

None can know what will come...of this little 'Woona'.

After committing a series of crimes that he may or may not have actually done, Bob is turned into a statue, sentenced to fours days of endless nightmares...

If you can call watching ponies doing weird, gross, adorable, and uncalled for things to each other nightmarish.

Which Bob does...

Warning:

Contains inappropriate jokes, statue humor, science, fo-dangales, and polly-winks.

A fic in which I'm surprised that no ones ever done :/

NOTICE: This is an unofficial and highly expanded story adaptation of the "PWaaMLPfim" Youtube Video Series: Phoenix Wright / My Little Pony FIM - Turnabout Storm! The videos came first, NOT this story!!!!

A quiet summer night in Ponyville takes a violent turn when two pegasus ponies enter the Everfree Forest and only one comes out alive, leaving the second accused of murder, on trial for her life. Ace Attorney Phoenix Wright finds himself dragged from his own world, magically summoned to Equestria by Twilight Sparkle to defend Rainbow Dash from charges of killing Ace Swift, a superstar pegasus athlete and champion racer.

Trapped in an unfamiliar world ruled by magical talking ponies, Phoenix must draw on all his wits and experience to solve the crime and uncover the conspiracy behind it... before Rainbow Dash is banished to the sun for a murder she didn't commit.

The dark tag is for the implications of the story.

An entry for the April 2015 write-off event, with the prompt “Great Expectations.”

It has been one of the closest guarded secrets of Canterlot's royalty. Deep in a specially constructed dungeon, surrounded by warding spells and powerful magic barriers, exists an enigma. Within a cage that could only be described as something out of a nightmare, it waits and watches all of Equestria. A creature that cannot age, is immune to disease, does not thirst nor hunger, and resists all injury. But, it also holds secrets and knowledge that could safeguard the kingdom. Its powers are frightening, but it is civil enough for debate when patience permits.

Princess Celestia has sought counsel with the creature before, enduring it making deal after deal for its services. The Princess walks a fine line when dealing with it, knowing full well anything could give it an advantage despite its imprisonment. She has had to go back on her word in these dealings, and from this a deep animosity between them has been born. It is a necessary evil as she is convinced this is a being capable of untold evil far and above anything Equestria has ever dreamed of. So long as it remains within the confines of its cell, her kingdom is made safe. So much magic has been woven to ensure that, there is little chance of escape.

So long as the magic holds, there is no danger. So long as the cage remains strong, the nameless creature stays enthralled in his cavernous dwelling. If that were to change--if the magic failed--not even the wisest could say. But one thing is assured, it does not bode well for Equestria.

With Crimson Storm and his friends stationed in Ponyville, the guild members must successfully balance their work and personal lives in order to survive. Family secrets will be revealed, friends become enemies, enemies will become friends and foces will clash as everything Crimson holds dear is threatened. Powers in the world are starting to move and all Crimson can do is wait for the oncoming storm.

Sequel to 'The Ranger's Journey'

There are consequences to every action, but we can't always predict what they will be. I stay up at night wondering what I could have done differently, but I've already paid the price for my actions. All I can do now is deal with the consequences, and I've got several great friends to help me do it.

This story is a sequel to Dash of Humanity

I'm stuck in Equestria, which reminds me of the dark ages. Instead of internet and fast-food, I have Rainbow Dash. She's been asked to help me learn to fit in... I'd like a refund.

I suppose we got off to a good start, aside from being told that after all I'd done I'd never see Earth again. So long as I can look on the bright side of life, and not get arrested for running pranks on everypony with Dash, I might just survive long enough to find my purpose in Equestria. So help me, however, if I get any vegetable related cutie marks I will choke a Princess.
