Death POV

'Come on, just a little bit faster, almost there', I knew it was gonna be close, I couldn't quite tell what was fighting the dragon, but I could tell they were about to die since that last attack just wasn't gonna cut it.

I was almost there, 'Closer, closer... NOW!!!' as I caused a sonic boom I shifted my position to deliver a hard kick to the dragon's face.

"HEY FUCKFACE" I hit him with a resounding crack knocking it back down the street, it appeared that for the most part the village was empty save for those last warriors that were just fighting the dragon.

I land in front of what I realized are fucking PONIES, I've avoided this dimension for nearly 3000 years now, and now I'm fucking stuck here, god fucking dammit, nevermind, more important issues to attend after all, can panic later, save this lot now.

I held my scythe horizontally behind me and said "let's see how you handle a real challenge shall we"

Now
3rd Person POV

The Dragon rapidly rose and charged straight at Death and struck him in the side with a claw, only for Death to catch the claw with one hand, shocking the ponies behind him as they stare awestruck at the sheer strength he possesses. With his left hand occupied he released the scythe to the ground and punched the dragon claw to make him let go, the hit had so much force the dragon growled in pain and tried to bite him, Death leaped onto the dragon's snout just before it got him and then stomped on the snout to force it to the ground.

The dragon recovered quickly and launched his left claw towards Death, who wasn't expecting a counter-attack so quickly and was launched into a building and was doused in Shadow Flames as the building melted from the sheer heat of the fire, the mane 6 watch in horror as their hope burns away.

The girls saw as the dragon turned back to them and fired more flames at them, they closed their eyes and flinched as they felt... nothing? They opened their eyes and saw a dark barrier separating the flames from them, they look around to see which unicorn was protecting them, but found no-one, the dragon looks confused until a boulder smashes into the side of his face, he roars in pain and turns to see who threw the rock.

"Ok, so clearly you haven't got the message quite clear, 'YOU... ARE... FUCKED'"

Death walks of the building, with the only damage being that his robe is in tatters.
"This was my favorite robe, and now it is ruined, I was going to painlessly rip your fucking head off in an instant, but instead I'll go with the option of purifying you, my own special brand of kindness"

Death launches at the dragon, smashing into the side of it's face, he then dives to the ground and delivers a massive uppercut to its underbelly launching it straight up, he then flew past it and started gathering immense amounts of lightning from the surrounding atmosphere into a giant ball of lighting 20 feet wide.

"Purifying Light" as Death spoke those words the ball of electricity glowed a golden hue and he launched it into the dragon, forcing into the ground kicking up massive amounts of dust and earth.

When the dust cleared all anyone could see was the dragon screaming in agony as death pumped it full of pure lightning.

10 minutes later
Twilight POV

For the past ten minutes the strange being has been hitting that Shadow Dragon with continuous lightning, it's screaming is painful just to listen to, fluttershy tried to get the being to stop causing it so much pain, but the lightning has formed a bubble of sorts around him and the dragon that shocks anyone to close, I'd try a shield spell to get close, but my horn is going to be useless for anything other than simple levitation for at least a week. We also tried shouting to the being, but it's either ignoring us, or it can't hear us.

I watch as Celestia and Luna, along with my brother Shining Armour and 50 royal guards land in both chariots and from flying.

"Twilight, what's happening here, what is that thing and what is it doing to that dragon?" Celestia asks

"I don't know, I wish I could tell you, but all I know is that that dragon attacked, used strange shadow flames, was fast enough to swat rainbow from the sky, withstood me using all of my power in one blast, which has damaged my horn by the way, and just as it was about to fry us all, that strange thing flew into it and kicked it hard enough to knock it away and then he withstood a direct blast of its flames, used a shield spell to protect us when the dragon attacked us again, launched it into the sky, and has been hitting it with strange gold lightning for the past ten minutes, and we can't get close because of the lightning, and he either can't hear us or is ign-" I'm cut of as an explosion drags our attention to the dragon, as a yellow dragon half the size of the shadow dragon is launched from the body of the bigger dragon.

The smaller dragon falls unconscious and the lightning dissipates, the shadow part of the shadow dragon collapses to the floor, and the strange being falls to the ground, seemingly exhausted.

Death POV

'Fuck me sideways that hurt' I stand up and crack my neck, I look around and see dozens of ponies, clearly guards of royalty surround me on all sides, spears in ha- hoof, I see three alicorns a few feet behind the guards to my left, there's a small one, probably a new alicorn since she's only the size of the average pony, she's purple and has a mane that is dark blueish and a lighter color as stripes in it, she has a star as her butt tattoo... I refuse to us the pony name for those things unless it applies to chil- foals, the next alicorn is larger than the first and her colour is dark blue with a flowing mane and tail that looks like space and the stars, it's awesome, her butt tattoo is a crescent moon on a blotch of black, next is the largest of the three and is clearly a fully grown alicorn, she is pure white with a flowing multi-colored mane and tail, green blue and pink, rather boring compared to the stars, but it does radiate power... well, compared to the regular ponies at least, she has a sun for a butt tattoo. Let's see how this plays out shall we.

I walk towards the alicorns and one of the earth pony guards says "Halt creature, you will step no closer to the princesses"

Oh now it's fun "or what little one, what will you, a tiny little pony do to me, the being who took down a dragon by his lonesome, hmm?"

"THIS" and he stabbed me, no fucking joke, the dude stabbed me with a spear. The alicorns look sickened by what he did, half the guards don't seem bothered, the other half clearly think he overreacted, personally I'm pissed off.

I look down at the spear and then pull it out of my gut, I spin it around in a show of skill, then smash it into his side launching him 20 feet away.

"You pathetic little rat, you would allow fear to control you to attack an unknown being, you are not worthy of being a guard."

The others look ready to attack when one of them, clearly a leader among them, a unicorn, he's white with a mane of blue and a lighter blue, he's bigger than the average pony, and he commands them "STOP, all of you, whoever this being is, he saved the princess of friendship and the rest of the elements of harmony, as well as cleared that dragon of shadow corruption"

He walks up to me and holds a hoof for me to shake, which is kinda awkward given how short they are, he comes up to the middle of my stomach, "The names Shining Armour, Prince of the Crystal Empire, as well as former Captain of the Royal Guard"

I shake his hand and announce loudly enough for them to hear "Death, the Angel Of Death, as well as the Angel Of Wisdom"

The look on their faces is priceless and I just smirk at them.

"You're the Angel Of Death?"

"Yep"

*Ahem* we both turn towards the full grown alicorn, she looks familiar, but I can't place it.

"Hello Angel of Wisdom and Death, my name is Celes-"

I cut her off "OH MY GOD, TIA, you actually became an ALICORN, HA, I fucking knew you'd become one, and does that make you over there Wittle Woona?" I tease with a massive smirk on my face. The guards just stand with their jaws dropped.

Looking to the small alicorn and the rest of the 'Elements Of Harmony', one of them, a unicorn looks immaculate with her white fur and purple mane and tail curled stylishly, her butt tattoo is 3 diamonds , the next is an earth pony, she's orange and has a blond mane and tail in a... pony tail... ugh, anyway she's also wearing a cowboy hat, she's probably a farmer, her butt tattoo is 3 apples, next one is another earth pony and well... pink... so much pink, her body is light pink, and her mane and tail are dark pink... they look like candy floss, her butt tattoo is a few balloons, next one is a pegasus looks like a gay pride flag, I guarantee she is at the very least bi, her body is blue and her mane and tail are fucking rainbow coloured, her butt tattoo is a rainbow lightning bolt over a cloud, and finally the most adorable thing I've ever seen, a pegasus and she's hiding behind her mane behind the orange one, she's yellow and has a light pink mane and tail, I already like her, I can't see her... y'know what, she's cute, I'm gonna call her's a cutie mark, but yeah, I can't see it.

The elements have different reactions to my words, the purple alicorn's mane seems to be springing about, the white unicorn has her jaw dropped like the guards, the orange earth pony, rainbow pegasus and the pink one all seem to be stifling laughs, and the adorable pegasus let's out an 'eep', I'm not sure my heart can stand her cuteness.

"HOW DO YOU KNOW THOSE NAMES" fuck me, I thought Faust used to scream loud.
