He once saved the earth from the demonic clutches of hell, this mysterious being now finds himself on a very different version of earth, with its own invaders...

(A Doom Eternal/ Conversion bureau crossover)

One million years ago, in the year 2017 A.D., humanity discovered two new types of radiation that were being emitted from an unknown region up in space. Using the Hubble space telescope, scientists were able to discover that the radiation was being emitted from an asteroid, which was on a direct collision path with Earth. 

These two newly discovered radiation types were dubbed Keifer's radiation (later nicknamed harmonic radiation) and Chaotic radiation. Keifer's radiation was found to be completely harmless to humans and animals, although it was later discovered that Keifer's radiation tended to be attracted to certain animals. Chaotic radiation, on the other hand, was found to be extremely harmful to humans in large amounts, causing fatal mutations to humans. 

The discovered asteroid was found to be over twice as big as the asteroid that wiped out the dinosaurs. In the year 2018, scientists predicted that the radiation was expected to reach fatal, critical levels by the year 2027. The asteroid itself was estimated to only crash into Earth one thousand years later, long after the rest of humanity would be wiped out by the lethal Chaotic radiation.

As a result of this, world leaders got together and began construction of Utopia, a large underground bunker, capable of housing four hundred thousand people, two thousand from each country. The chosen few were gathered together within Utopia and would be the last of humanity.

However, the radiation was estimated to have a half life of at least 1,000,000 years. This led world governments to invest heavily in suspended animation and cryogenic technology. And finally, in the year 2024, the first cryogenic pod was invented, capable of freezing someone for an infinite amount of time, without the need for sustenance, as long as there was a power supply.

Exactly one million years later, the humans reemerged to begin recolonisation... only to find several sentient species currently inhabiting the planet that they once had absolute, unchallenged authority over. 

One of them was humanity, which was able to recolonise and repopulate the planet from the few members of the human race that managed to survive the Second Flood, long before the Utopians woke up. But there was something wrong, humanity was being used as slaves by the ponies and several other species.

How will humanity answer to the fact that Planet Earth (now renamed Equus) is no longer theirs? Will they make peace with the locals, or will they attempt to wipe them off the face of the planet with their stockpile of nuclear weapons, that were there for the very purpose of reinstating human rule if another creature evolved to their level?

This is the old version of this story. The rebooted version is available here:

Beyond Earth Phoenix Rising

To the far east across the vast sea is the forgotten homeland of the diamond dogs. A land once full of poverty, sickness, and famine has become an industrial super power that threatens Equestrias economic dominance/standing. Can Equestria survive as countless ponies are put out of work from the influx of cheaper and higher quality goods from Britannia or will they be forced into an war against a technologically superior foe? And just who is the Emperor and is every thing they know a lie?

This will be an anthology series focusing on the various individuals who have been effected by the Conversion Wars. Actions can have far reaching consequences that effect even those you wouldn’t expect. (Critiques and ideas are more then welcome for this story.)

On July 17th, 2023, satellites around the world began to pick up a strange radiation source coming from the North Pacific, just above Hawaii. Just as the US, Japan, Australia and other such nations along the Pacific begin to investigate, something covers the entire North Pacific in blinding light, a loud crack rippling through the air. When the light finally died down and humanity rubbed it's eyes in shock, they saw none other than Equestria.

The first contact had gone well enough, with pony and human delegations meeting in New York, Celestia herself showing up for a moment. They claimed that the appearance of Equestria was purely accidental, a 'magical mishap' as they put it. They established 'Conversion Bureaus' around the globe, establishments for the sole purpose of permanently changing a human into a pony.

As it turned out, this was all a ruse. Shortly after the final conversion bureau was built, Celestia herself declared humanity to be a 'vile' and 'unfit' species, citing examples such as their wars, their pollution, and so on. All at once, the Conversion Centers released hordes of Pegasi and Unicorns, bent on forcibly turning all of humanity into 'peace-loving' ponies.

All at once, millions of humans were transformed. Military bases sabotaged. The world couldn't even get a missile out of the ground in time, much less perform a coordinated counter-assault. Humanity simply wasn't prepared for this.

But as it turned out, there were other players in the game. Humanity had gotten out of fixes much worse than this before, and they didn't even realize it. Organizations, unknown to even the world elite, sat beneath the surface of the Earth or disguised as ordinary facilities, prepared to do everything in their power to prevent the extinction of humanity.

As humanity panics, the SCP Foundation takes action.

A Prequel to Negotiations

Please Help Out The NegotiationsVerse TV Tropes Page

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.

Many years after her dethronement, Chrysalis has returned to her kingdom, but not in the way her people had secretly feared. Chrysalis appears to have changed the same way the others have, although some believe she is using her shapeshifting powers to do so, something that is believed impossible. While Thorax is willing to give her a chance to prove she's changed, Pharynx is not convinced of her reform. The King of Changelings calls his closest friend Spike in order to aid him, but will that be enough? And has Chrysalis truly reformed?

When the ponies came, they tried to convert humanity with words and kindness, saying that they were misguided beings and the princesses would help them on the path to Harmony. When that failed, the ponies tried the potion, only for it's magic to be countered by humanity's science. Then they tried force and failed completely at that.
Finally they decided to let the Barrier defeat humanity and it seemed to work! Nearly 50% of the planet was covered with humanity doing it's best to find a solution.
Unfortunately, the ponies of Equestria are about to learn a harsh lesson that humanity learnt long ago. The Earth can be paradise for those who tame it, but to others it is hell.

Smolder’s going to the Dragon Lands for the Feast of Fire.

I really don’t want her to.
