The planet of Chikyu is pretty odd, from an outsider perspective. There are anthromorphic sapients of every stripe and sort, the world president is a dog, its greatest warriors are alien monkeys, the average IQ (outside genius scientists or children) is somewhere below 50, and magic orbs raise the dead. How much difference would adding a pony that barely talks really make?
...quite a lot, apparently. Just ask Mr. Popo...if you dare.

When Equestria appeared on Earth and discovered the MLP fandom, the initial reaction was of interest. Then they discovered the terrors of The Conversion Bureau, and there was only one way for them to react...

Humanity is dead.
It's members have been converted and brainwashed. Its homeworld has been absorbed, and its culture has been eradicated.
Princess Celestia couldnt' be happier.

Unfortunately for Celestia, there are beings out there who don't look too kindly on xenocide. Beings much more powerful than her...

Inspired by Rush's "The Conversion Bureau: Celestia's Silly Plan"

Author's note: For the record, I don't hate all TCB fics. My problem is with the ones that depict humans as irredeemable bastards whose only hope for salvation is to convert themselves into talking horses. They piss me off. They really piss me off.

Let's summarize a bit shall we? First guy named Ghost (not real name you can think of a name of you want) goes to a con dressed as the Courier. Second he has multiple weapons with infinite ammunition of each type, like .50 explosive rounds. Finally he is OP as all fuck and probably cannot die.

Complete supplies list
Anti-Material Rifle (GRA)
A Light Shining in the Darkness
Maria
Riot shotgun
Survivalist's Rifle
This Machine
Sprtel-Wood 9700
Stimpack
Rad Away
Med + Rad x
Doctor's bag

Infinite ammo for each weapon
Infinite ammo types for each

Things were good in New Vegas. The Courier had secured New Vegas as it's own territory under the NCR, Raider activity had plummeted, and Cesare's Legion was on the run. However, Mr House had left 1 last trick, a teleportation device to send the Lucky 38, and everyone within it, somewhere that they would be unable to enjoy their rewards.

A little place called Equestria.

Inspired by Wasteland to Wonderland by Dragonman461, give it a read.

Batman has defeated many foes in his life. The Joker, Two Face, The Riddler, Poison Ivy...just to name a few. However, no matter how hard he tries, there was one foe he could never defeat...Time.

Finally beaten, he admits defeat, ready to give up...

But a tiny white unicorn might have something to say about that. A single word that gives him hope. A legacy. A way for Batman to conquer time itself, even if Bruce Wayne cannot.

That word...is "Father".

Part of the PWNY-verse.

Many people have many theories about Scootaloo. Some think she's an orphan. Some think she's part of an abusive household. Others still worry that she's somepony's illegitimate offspring that's hidden away.

However, the truth is far from that. She has a loving mother and father, and she means the world to them both. They've gone to great lengths all for her.

However...they're just a little...strange. Especially since neither one is comfortable with coming out except at night.

Rated Teen for some adult language.

Partially inspired by this story by Colonel J.

Edit 2: And G_Haze has decided to update the cover art, and damn does it look good.

He was an alien raised by humans, torn between two worlds and belonging to neither. His efforts thwarted, he found himself descending into madness, destined to be consumed by the nightmare he was becoming.

She was a loner, withdrawn and anti-social. When one whose regard she valued above all others turned away, she sank into darkness and despair. The madness waited.

The madness drove him to decide that if the world could not accept his enlightenment, it would suffer his madness.

The madness drove her to decide that if the world had no place for her, then it could do without her.

Sometimes, it takes another broken soul to help put your pieces back together.

Edit 2: Since everyone keeps asking, this is a crossover with the 'Mother' game series. Look it up.

Scootaloo's life has always been shrouded in mystery. She lives in her house in Ponyville alone. She often disappears with no explanation. And no one's ever seen her parents.
She keeps it that way deliberately. She likes her normal life in Ponyville, and has held on to it as much as she can.
However, a personal tragedy brings family responsibility down on her shoulders, and her life is about to spiral out of control.
Thankfully, she has quite a bit of help keeping both her lives stable - and separate - as much as possible...
...a dragon chef who can't make a salad without making it flambe...
...a cripplingly far-sighted ex-assassin hippogryph maid...
...a slim built minotaur gardener who is as innocent as he is unexpectedly strong...
...a mechanical golem head servant whose brain runs - badly - on hot tea...
...and one devil of a butler.

This story is a sequel to Melody of the Future

Two friends separated by circumstances and eras...

Both return to the same time and place, back to their own world, their old lives.

But both have changed greatly, and they did not return alone. And both carry scars of what happened to them, inside and out.

Can these two pick up the pieces of their old lives, and go back to where they were? Or will they perhaps become something more?
