A rewrite is coming soon. Please don't read this how it stands, it's bad.

T for Teen. Violence, and Major swearing. Fallout 3 crossover, because it hasn't been done before.

After the events of the Canterlot Wedding, the Changelings regroup and plot a return. Upon their comeback, they successfully imprison every live equine in Equestria into cocoons within the span of a year. Nesting in the mountain next to Canterlot, the Changelings feed off of the thousands of ponies' love, claiming Equestria as their own.

Many years after their triumph, one pony escapes her cocoon prison through sheer luck, discovering Equestria to be a dark and barren wasteland of dead trees and no existing plant-life. Searching for any means of survival that she can find, the individual pony seeks a safe place to hide from the Changelings hot on her tail, knowing that if she gets captured again, they will put her back in her cocoon where she will be trapped for the rest of her life, dooming her kind forever.

Beyond Earth and beyond the Universe within which Earth exists there is a place full of love; the richest mine of love that can be found, as it is seen by those capable of utilizing it...

Within that place, specifically a part of it called the Everfree Forest, awakes one such creature: a Changeling; specifically, a Changeling who had been a human on Earth the day before. How will he survive in a body that literally needs love for nourishment, while in a world that is now wise to the Changelings' tricks and has branded them evil? Better question: Will he be able to change more than his physical appearance?

These questions are not the only thing that will plague him, for the hows and whys of his arrival and transformation are in a hurry to reveal themselves, and Equestria's heart will stop as it waits for its fate to be decided.

Now with a side story (with more to come) from other characters' POV!
POV: MANE SIX

Doppel Ganger is an outlaw changeling who has been living in the Everfree Forest for more than a year. Far from all the ruckus his Queen caused with the invasion, he spends a quiet life stealing love from Ponyvillians with his two friends, Camouflage and Mimic. But an encounter with a manticore will give him the worst thing he could catch, a cold.

This seemingly mild illness has terrible effects on changeling's physiology. At each sneeze, the changeling will either lose his disguise, or get a new one without any control over it. Now, it's harder to feed on ponies’ love unnoticed.

Doppel will have to feed on love in Ponyville during the duration of his sickness.

Jack is different. Not from just his age group, but from others as well. Cold, calculating, and tactical are but a few of the words used to describe him.

But when he is thrust into a new world, when he is attacked and nearly left to die by those who stand for love, tolerance, and friendship, what will happen from there?

Plans, power, corruption, and the seeds of a dark new age will be sewn. For such schemes are the ways of those who hide behind masks. Follow the story of Jack, and learn the Markings of a King.

This story is a sequel to A New Friend

It has been more than a month since the events in the changeling hive took place in the last story, "A New Friend". Chrysalis, now left without her changing ability and magic, has gathered her changeling swarm with the help of her daughter, Princess Naractia. Now she plans to get revenge on the ponies that caused her to lose her power.

However, Naractia hears her plans and flees to Ponyville to warn everypony about Chrysalis. But once she leaves the hive, Queen Chrysalis sends a group of changelings to kill her daughter. Now the only one who can help Naractia is Rowan, a unicorn from a different world, student to Princess Luna, and wielder of the Element of Courage.

Vanilla Torte lives an unassuming life outside of Canterlot, never thinking much about the huge city above.

Then something lands with a thunderous crash in his garden.

Third installment of the Leech series - you'll need to read the other two first to understand this. I apologize for this in advance.

After months of being worshipped as heroes, Trixie and Leech must finally face normal life as Canterlot citizens - it seems in the superficial culture of Canterlot, even heroism has a shelf-life. After the furor has died down, Trixie has begun working the cabaret circuit with her magic shows - but can she compete amid Equestria's most talented and powerful unicorns? Her discovery of a new power may help her...

Meanwhile, just how does a changeling with the IQ of an empty potato sack get by in a society with such incredibly high standards?
