The lone pony stood atop of the former guardian of Tartarus, the three-headed dog's middle head was completely removed. The one on the right was suffering from a case of cranial trauma that would make even the most experienced doctors lose hope. The right one had it's neck slit.

"Was this a joke? Well haha it was hilariously easy to pull off."

Death stood at the portal to the underworld, smiling at his general's work. "Well done. I knew he would stand a chance against the price of death."

The stallion let out an overconfident laugh. "One day, I will take your place you old workhorse."

Death's expression didn't change, or maybe it did, but the lack of any muscle, tissue, or hair made it difficult to decipher his emotions. "Don't get carried away boy. You may have earned your freedom from my domain, but you owe me a debt that has yet to be paid."

The stallion rolled his eyes. "Yeah yeah, but first I need to pay a visit to an old friend."

"Why?"

"He needs to learn what happens when you cross my path."

"Very well, but make sure he suffers first. Souls are easier to work with if you take the fight out of them."

The stallion nodded before proceeding through the portal that separated the land of the living and damned. The first thing he noticed was air. It filled his hollow body with a vigor that once was lost to him. The cool evening breeze went through his grayed mane. His eyes, once filled with life, now scanned over the landscape. It looked like the area had been recently burned of all life. Not even the birds sang in this desolate land.

Once We finish our business with our friend, we will find the one responsible for our death.

Yes, yes we will.

The pony focused his magic into his horn for a long-range teleport. This would tire him, but it would get him out of this land. He didn't want to spend another moment this close to his damnation.

You still remember where it is right?

Of course, how could I forget?

In a flash, the pony was gone, leaving only a scorch mark where he once was.

In another nanosecond, he reappeared in front of a huge cave complex. The caves were not natural, one look said that. They were hexagonal in nature and if you listened carefully, you could hear a faint buzzing. The pony started his trek into the caves with a small smile adorning his battered face.

Why is it that whenever were about to do something, you smile?

I don't know, but it's what I do.

Cool story bro.

The first signs of life he had was that of the faint glow of magically crafted rocks that sat on the walls.

Funny, I thought that changelings didn't need these.

They usually don't.

He continued down the hallway until he found his target, the changeling central hive. What was strange was that they didn't mind him much. Normally they would have already tried to kill him.

The strange gets stranger.

Lets get to work.

Should we assume our full form?

We better, these are airborne targets.

One cue, the stallion grunted as his back opened up and a pair of skeletal wings showed themselves.

Why does that hurt?

Probably because were fusing magic into bone and making it grow spontaneously.

Probably.

This seemed to get the attention of the changelings. The pony chuckled "Well then, let me show you all why I am the most powerful being in this dimension."

He flapped his wings, causing him to rise into the air.

Destroy?

He started to charge up his magic. Some of the changelings decided that this asshat was about to throw down and rushed him, only to be incapacitated by a magical shield.

Hmm, you didn't use the lethal one.

I'm going to kill them anyway, might as well use something that doesn't require a huge amount of magic.

More changelings threw themselves at him, only to be shocked violently and fall to the ground. Opening his now glowing eyes, the pony smiled as he cast his spell "Burn bitches burn."

The spell made the heat of the room heat up to about 600 degrees Fahrenheit for a split second, flash cooking the changelings in their shells.

Ha, I love that smell.

How could you? It smells like a gym locker that had an orgy from the shit people from the land of Uranus in it.

Exactly

The pony landed, winded from the amount of magic he just used. "My master would've been proud of me to see this kind of carnage."

What he didn't know was that he had just killed 90% of all the changelings in a five hundred mile radius, putting them on the endangered species list.

Only one survived the initial attack. A changeling who had only gotten luck from the blast. He shot a magic blast at the unicorn, but it didn't even phase him. "I won't let this atrocity go unanswered for. I will kill you."

The changeling rushed the unicorn, hoping to actually do something against him. As he reached the unicorn, the pony immediately vanished from his vision and the changeling felt himself loose control of his wings. He hit the ground hard. It took him a second to realize that his wings were now missing, but that second cost him his life. With a swing of his wing, the pony removed the changelings head.

Such a waste of life

He chose his end, an honorable one even if it wasn't a smart move.

I'm not detecting anything living in this hive except the queen.

That's bullshit. My attack wouldn't have killed him.

Maybe the queen knows.

The queen as it turns out had a hidden panic room that was unknown to all other changelings and couldn't be breached by any conventional means. So it was completely insane to find out that a pony, not even an alicorn, teleported into the middle of the room.

The unicorn shook his head. "I hate teleportation. I can't keep this up. I'm tired." He looked over at the queen. "Chrysalis is still the queen here? Well then, lets make this a pleasent visit between friends."

Chrysalis was not amused. This pony had single hoofedly exterminated her hive, their screams still echoing in her mind, and was now staring at her and using her name. "H-how do you know name?"

"You should know me. Now, if you would be so kind as to tell me where Mirrors Edge is so I can congradulate him on a job well done."

"I refuse to tell you."

The pony sighed. "Wrong answer."

He dashed forward and in the blink of an eye was in front of Chrysalis. Even faster, he brought is right forehoof under her and into her stomach. He then proceeded to slam her into the wall of the panic room.

"Now then, why don't you tell me where my friend is before I get mad."

"I-I can't find him. H-he isn't part of my hive mind."

"Bummer." The unicorn brought his hindleg into a kick into the queen's chest, breaking the chitin and letting a lot of green ooze leak onto the floor. "Now I have to kill you."

Chrysalis wasn't having any of this had fired a small, but powerful beam of magic through the area where the unicorn's heart should be.

"A for effort, B on execution, F on effect. I'm undead, you would have to destroy my brain in order to kill me."

"Impossible."

The unicorn sighed, and used his demonic wing to cut off Chrysalis's horn. The queen screamed in agony as her world was fading from view. He then shoved his forehooves through her chitin and ripped her in half horizontally, so that she was still alive, but barely.

"I shall tell you my name before I kill you."

The unicorn lied and used his forehooves to smash Chrysalis's skull in.

"My name is Sigma."
