Walter Pilgrim was bored since he was in decent shape he came to this convention as one of his favorite characters, Volthoom from DC comics.

He made his costume from a dark gray full body suit that covers everything except his face, which he painted gray, and he used optic fiber spread throughout the external surface of the suit in a nervous system like pattern coming out of the of a black circle on his chest, which hid a small battery and a set of LEDs connected to the fiber.

Walter walked around for awhile before he saw a stall that was selling many items of varying franchises, he approached the stall and he saw a merchant cosplaying as the Merchant from Resident Evil 4.

“Greetings, Volthoom the First Lantern,” said the Merchant.

“Hello,” said Walter as he looked around until he saw a box with two rings, not just any rings but the Phantom Lantern Ring and a Black Lantern Ring and beside them was a metallic gray railroad lantern, it was the Travel Lantern, the lantern that was the base for all Power Core of all Lantern Corps.

“How much for the pair of rings and the lantern?” asked Walter.

“How about 300 bucks?” asked the Merchant.

“Well, it’s really well made and it’s the best thing I could find so far, so why not?” said Walter as he paid the Merchant.

“Pleasure doing business with you,” said the Merchant while Walter was putting the Phantom Ring on his right middle finger and the Black Ring on the left middle finger.

After picking the Travel Lantern Walter was about to see if he could find something else to buy in this convention when he tripped and everything went blank.

Thousands of years later beneath Canterlot in the Crystal Caves

Inside a chamber carved from the crystal inside the mountain where the city of Canterlot was located was a box with many runes etched on its surface.

The walls of the chamber have the same runes carved on them, these runes existed to seal the power of a certain ring that was inside the box and inside the ring was Volthoom. This was actually the second time he was sealed, the first time was after the fight against the late King and Queen while this time was after the fight against their daughter.

Volthoom was bored, he managed to watch his memories, from his first memory to the moment he was Displaced, and the memories of the original Volthoom, from his first memory to the moment he died in “Wrath of the First Lantern”, including all of his 10 billion years chained in the Chamber of Shadows but at this point it was like reading a book or watching a movie and he knew it wasn't him so he wasn't affected by it, to be frank, it’s like watching a movie multiple times, a movie with a 10 billion years duration.

You must be thinking, how it was possible to scroll through 10 billion years of memories multiple times in just a few thousand years? It’s pretty easy to do this if you can think in the speed of light.

In fact, he had to keep series of mental blocks to be able to think at normal speed, a.k.a. the speed of most beings on this planet and he could remove these blocks if he wanted.

Regardless of the speed of his thoughts he was stuck inside the Phantom Ring and unable to get out without the help from someone from the outside, never mind the fact he was Displaced in the version of Equestria in which its inhabitants were of the anthro variety.

Yes, anthro as in ponies that walk on two hooves with hands and the general figure of a human just like in those fanfictions on the internet.

It started right after his encounter with the Merchant…

Thousands of years ago outside of the Equus atmosphere

Walter woke up falling, he panicked and started to freak out.

After a few minutes freaking out he started to calm down and after calming down he noticed that all around him looked like outer space.

Looking “up” he saw a rapidly approaching planet, he raised his arm in a futile attempt to protect himself and with the speed of a meteor he crashed on the ground creating a very wide crater.

Instead of being hurt he noticed he was fine and inside of a white sphere made of light. He looked at the sphere and noted that it was made of a hard white material, at least he was unharmed, now how he will get out?

Not a moment later the sphere slowly disappeared, then he looked at his right hand, more specifically at his ring and saw the ring glowing, if that was a hard light construct than that meant only one thing.

He pointed right hand forward in a fist before he concentrated and a group of floating swords made of white light appeared.

“Wow, awesome,” said Walter noticed a change while the swords dissipated.

“What happened to my voice,” said Walter in a deeper and older voice as he brought his left hand to his forehead.

Looking at his hand he saw glowing veins/nerves inside his arms, which was an almost see through gray in color, he looked at the rest of his body and he saw the same change and inside his chest was a black orb from which the veins/nerves come out.

He needed to find a mirror or something similar, then he started to float up but if he was right he could control this ability. He concentrated and he manages to control his position in the air. So he looked around the crater he eventually found the Travel Lantern.

Picking up the Lantern he contemplated how to transport it with him, but then he remembered the comics, so he lifted the lantern to his chest and phased the Lantern inside the black sphere inside his rib cage.

Slowly he flew out of the crater by going upward and stopped when he could see a fair amount of land, it was a forested area. When he spotted a lake not far from where he fell he flew over there and landed on its edge before leaning forward to see his reflection.

If there was doubt in his mind before, they were gone when he saw that he was in the body of Volthoom the First Lantern but unlike Volthoom he didn't have a face, his head was blank except for his glowing eyes, eyes that glowed the same colors as his veins/nerves in his body.

Hearing the sound of multiple people approaching he turned around and saw people, granted they weren't humans but considering that he just became Volthoom the fact that they weren't human was the least absurd. Their height ranged from 4ft to 6ft, they possessed sexual dimorphism, the females had breasts on her chests, wider hips and narrower waists while the males had broader shoulders and narrower hips and no breasts and they had a biped configuration with two arms, all in all, similar to humans.

But unlike humans their legs ended in hooves instead of feet, they had three fingers and a thumb, they had eyes with a variety of colors, while they are all covered in fur that also came in a variety of colors they wore clothes and all of them had either butterfly or dragonfly-like wings on their back and lastly their faces had equid features including muzzle and ears in a higher position than humans.

All of this was analyzed by Walter in a fraction of a second, it seems he can accelerate his thought to match the speed of light if he concentrated enough. He returned his thoughts to normal speed, then he saw one of them approach him while the others whispered to each other. The one that was approaching is a 5ft 6in tall female with butterfly-like wings, light blue fur, light pink flowing hair and tail and magenta eyes while wearing a simple red sundress.

“Greetings stranger, can you understand me?” asked the colorful female winged anthro equine.

“Yes I can understand you,” said Walter using his new deep and old voice, he noticed that it had a slight echo in it.

“By the gods, that's a relief, would you mind answering a few questions?” asked the female.

“I don’t mind, but I also have a few questions as well. How about we trade questions? Seems reasonable enough,” said Walter.

“That is agreeable, by the way, my name is Wind Drifter,” said Wind Drifter as she motioned that it was safe to get closer.

Wind Drifter sat on the grassy meadow at the margin of the lake, the others followed suit, sitting around Walter like a group that was about to hear a story.

Walter sat in the lotus position and just stared at the group, it was difficult for them to guess where he was looking because he didn’t have visible pupils, some of them probably thought he was blind.

“Would you mind telling us your name?” asked Wind Drifter.

In the second after she asked that question, he thought on many scenarios of how things might go and considering everything he managed to learn just by observing he made a decision.

“My name is Volthoom,” said Walter as he embraced his new name.

“Greetings Volthoom, my first question is why are you here?” asked Drifter.

“It wasn’t my intention to be here, wherever here is,” said Volthoom.

“You don’t know where you are?” asked Drifter and Volthoom nodded.

“You are in Flutter Valley the home of flutter ponies, just south of the newly formed nation of Equestria,” said Drifter.

The moment Wind Drifter said “Equestria” everything around Volthoom slowed down. He was in a world with anthropomorphic ponies in front of him and in the body of a fictional character, he concluded that he somehow ended up in the setting of MLP: FIM.

The Merchant could have sent Volthoom anywhere both on the world and on the timeline, at least he established that is south of Equestria, which is good but the only place south of Equestria in the “present” of the show that he knows of was the Badlands.

So he was either in the ancient past before whatever event made Flutter Valley into the Badlands or in a distant future where the Badlands became a lush green forest, for all he knew this flutter ponies might be the changelings’ descendants.

He relaxed and the world around him resumed its normal speed, he needed to confirm one of the two possibilities, his entire freak out episode happened too fast for Wind Drifter and the other to notice that something was wrong, to them he just moved slightly from his original position.

“Who rules this ‘Equestria’?” asked Volthoom feigning ignorance.

“That would be King Luminous Sky and Queen Lush Meadow,” said Drifter.

Volthoom pondered that fact still not knowing where he was on the timeline but at least he knew that this Equestria was vastly different than the one he saw in the show.

“My turn, where do you come from?” asked Drifter.

“I come from a faraway world called Earth or Terra, I was sent here against my will when I fell into your world,” said Volthoom unaware of the effect his words had on them as they started to talk among themselves.

“Do the rules of Equestria have any offspring?,” asked Volthoom hoping to confirm one of the two possibilities.

“Yes two fillies, Celestia and Luna who was born recently,” said Wind Drifter clearly nervous to be in his presence after he said that he fell from the sky.

Now Volthoom knew he was in the distant past if Luna was just born.

“Are you a god?” asked Drifter nervously, which surprised Volthoom. He had to answer this question very carefully because his answer can have far-reaching repercussion.

“It depends on your definition of god,” said Volthoom trying to not give a clear answer because with Volthoom's power he might as well be a god.

This seems to have the opposite effect on them as all of them immediately got on their knees and bowed before him, despite having a body made of mostly light he could feel a headache coming.

Present day

Volthoom, who perceived the world outside of the box in a manner similar to a sonar but with energies of the Spectrum instead of sound, was jolted out of his flashback by a very strong knock on the sealed door. This continued until the door was broken and a group of changelings entered the chamber followed by a changeling queen.

The changelings were about 5ft~6ft tall and had an androgynous figure as they didn't have a fixed gender, also they were on their “battle form” with thick black chitin covering their bodies almost completely, with the exception of their abdomen and lumbar, it was dark green instead of black, blue “lenses” over their eyes, which was in fact a second eyelid, shells on their backs like beetles to protect their wings and their tails were as long as they are tall, segmented with spiked thick rings of chitin and a blade on its end.

The Queen, on the other hand, was 9ft tall and has thinner and more flexible chitin that appearance-wise looked just like black skin, except on her abdomen and lumbar, the “skin” was dark green making her look as if she was wearing a corset made of bands or belts arranged horizontally.

The only additional cover she had were the layers of black silk that were around her breasts acting as a strapless bra and a long black skirt made of the same silk with a hole in the back just above her butt for her tail, which was without the rings of chitin showing smooth black “skin” before ending in a thin blade.

Both the Queen and the warriors not only had holes in their arms and legs, plus the exposed wings in the Queen's case, but there were also thinner than normal, the latter was more visible on the Queen who was without armor, clear signs of starvation and malnourishment.

“At last, we found you, my lord, soon we will release you of your prison, just wait a little longer,” said the changeling queen while she gently held and caressed the box Volthoom's ring was in.

Carefully she handed the box to one of the changeling warriors before giving the order, “Make sure this reaches the summit, while I keep my cover.”

“It will be done Lady Chrysalis,” said the warrior that received the box.

That was interesting, changelings normally say “my queen” to their leader, they only use “Lady” when addressing to the queen of another hive, this told him that this operation was the combined effort of at least two hives.

Before the warrior left, a green fire engulfed the Queen changing her appearance, now she was an alicorn mare with pink coat, magenta eyes and a mane and tail with hues of dark pink, purple and pale gold that ended in curls, she was also wearing a wedding dress and was a little over 6 and a half feet tall.

“This day is going to be perfect~~,” he heard the singing voice of the disguised Queen before being carried outside of the mountain for the first time in who knows how long.

Author's Notes:

Volthoom will have his power reduced for the simple fact that for him to achieve the level of power he has in the comic he has to feel emotions so strongly that leaves him mentally unstable.

He will only be able to create hard light constructs of any color and use their properties also he can use the White Light of Life to connect himself with the elemental forces like The Green, The Red, The Gray and The Blue.

If he blocks his emotions completely he becomes able to use the Black Power Ring and connect himself with The Black, otherwise, the Black Ring is just an accessory that will corrupt anyone but Volthoom.

Lastly, the bladed tails of the changelings are similar to the xenomorph tails in their "battle form". In their default form their tails are smooth chitin with the blade, in the end, the blade, however, is dull and smaller in their default form.

If, you are having difficulty visualizing Chrysalis here are some pictures to help, they were also partially what inspired me:
