Author's Note

Pictures belong to their rightful owners, I simply found them on Google Images when I searched for Demons. I own nothing in this chapter except the plot, Dark Angel, and the names I gave the demons Dark Angel knows.

Chapter 1: Demons in Equestria

Demons in Equestria

The Everfree Forest, one of the most dangerous places in Equestria, and also seen to be a home to many dangerous creatures. However, there is a dark evil lurking within this forest, one that is far more powerful then Nightmare Moon, and holds demons from Tartarus itself. They are dangerous, and anypony would tell you the same.

Over near the castle of the royal twin sisters, a lone figure stood on top of the ruins, one that stood up on two legs, held a wingspan that would put Celestia to shame, and also wore robes that covered everything, even the face. He held a long claymore made of unknown, black metal, which seemed to give off both a blue and red aura. There was also a faint glow of red from his left hand, and a blue glow from his right hand.

The being was known as Dark Angel. Half Demon, half God.

Dark Angel stared out across the Everfree Forest, and spun his claymore before he jumped off the top of the ruins, and his wings flapped a couple times before aiding him in gliding across the large gap that held no bridge. He then landed in front of said forest, and spun his sword around before placing it across his back, and walking forward. He appeared to be unnoticed by the creatures of the night, and even managed to pass by a few Manticores with ease.

Just then he heard a low groan, and looked to the sides, seeing demons beginning to surround him.

This made Dark Angel take a step back, and wrapped his right gauntlet around his black claymore, causing the blade to pulse in blue magic, and shine slightly. Dark Angel didn't move, but instead waited for the other demons to move. Playing the cautious card.

A demon then lunged at him, making Dark Angel pull the blade out within moments, and slice downwards, cutting the head and torso in half, while causing blood to splatter everywhere. This made the other demons roar in anger, and all charged at Dark Angel, who had a smirk hidden under his hood.

...

Dark Angel slowly pulled his claymore out of the last demon, revealing the blade to be covered in blood. This made Dark Angel swipe the blade through the air, sending the blood onto one of the corpses, and then sheathed his blade against his back. And with that, he began walking again, as if unaffected by what just happened. Though he appeared to have blood on some of his robe.

Dark Angel continued through the forest, looking around every once in a while to see if there was something nearby. But there was yet to be anything. The forest was quiet, and the animals seem to have stopped back a ways. This made Dark Angel slowly place his gauntlet on his sword as he continued through the night, before he spotted two more demons ahead of him, two that he knew all too well.

Dark Angel stayed silent as one of the two spoke. "Hmph, if it isn't Dark Angel, a mistake between one of our traitorous allies, and your whore of a goddess."

Dark Angel didn't respond, and simply pulled out his claymore, grabbed it with both hands, and made it glow half red, half blue.

"Relax, you disgrace, we have no intentions of fighting you. We came to warn you."

"Yes. You cannot stop us, for we will be filling Equestria with our forces within 36 years... sure, a bit slow, but we'll turn it into our new home."

Dark Angel spoke in a very deep and almost dark voice. "You are telling me this... why?"

They both snickered. "Because none of the residents of this world will believe you about us. We figured there was no harm in telling someone we... have aided once before."

"Agreed. We owed you one, so we are repaying our debt. This land will be covered in darkness, and you won't be able to save it."

Dark Angel placed the claymore against his back as he began walking, pushed past the two, and ignored them as one called out. "There's no point in continuing, Dark Angel! Just give up already!"

Soon they were too far to be heard, making Dark Angel sigh heavily as he kept pushing forward.

Eventually he came up to what appeared to be the borders of the Everfree Forest, and saw a lone town ahead. This made him smile, and walk towards the town. Once there, he could see where demons once stood, and began hunting them down.

...

Doctor Whooves smiled as the Tardis stopped near Ponyville, then stepped out into the night sky, and looked at Derpy who came out. "Well, here we are. 36 years in the past... why did you want to go here again, Derpy?"

She smiled. "I wanted to see myself as a foal!"

Doctor Whooves chuckled lightly, then narrowed his eyes as he heard a loud crash and something that sounded much like a sword being drawn. This caused him to look towards the town, and went wide eyed upon seeing a strange creature, pinning a kind of monster to the ground, before stabbing it's large claymore into said monster's throat, and twisted harshly.

Doctor Whooves stepped back in shock, never seeing this last time he came here. He wasn't sure what it was, but it was dangerous.

Just then the creature looked at the two, making Doctor Whooves go pale, before the creature threw it's claymore. This made Doctor Whooves go wide eyed, before the blade went over his head, and stabbed into something that gave out a long gurgle.

He looked back to see another of the monsters on the ground, the blade deep in it's throat.

The creature then walked over to the two, pulled the blade out of the monster, then simply glanced at Doctor Whooves, before heading back into town, and attacking one of the nearby monsters.

Doctor Whooves then looked at Derpy. "Maybe it's not such a good idea to be here, Derpy."

"Why?"

"Um... I'll explain once we're gone."

"Um... okay."

The two then got into the tardis, and were gone.

...

Dark Angel finished killing the last demon, and let out a soft sigh as he set the blade against his back again. He looked around the town, and was glad that he could protect it, before thinking of something. This could be where his base of operations would be, but he'd need a way to interact with the other ponies and keep anything hidden.

So, with a few second thoughts, he headed for one of the nearby buildings that were empty, and got to work with making his body. Given his power, and the spells he's been taught, this should be easy.

...Next Morning...

Everypony around Ponyville awoke from their good night sleep, and began to do their daily activities. The town was peaceful and everypony seemed to be happy. Perfect harmony.

In one of the largest buildings nearby, Dark Angel finished his spell and looked over his new body.

It was tall, given the other ones he's seen, and had a black coat with white markings running along it's legs. It's mane and tail were balanced with two separate white stripes, and two separate black stripes. It had a cutie mark of devil horns with a halo over them, and had a horn that was pure white. Should do for now. So without a second thought, he entered the body, and made it open it's eyes, revealing a single red iris with the other being a blue iris.

Dark Angel sat up in his body, and had it scratch it's ear a little, before looking into the mirror, slightly displeased that the two eyes didn't fit, but he will have to go with it.

He climbed out of the bed he was working on, and headed downstairs, where he soon found a key to the front door, and headed outside, locking the door behind him, and headed off into the crowd, who all didn't seem to even notice anything strange about him.
