Doom Slayer Reborn: Fall of Equestria

Prologue: A Wish and A Slayer is Born

Far from the prying eyes of the dreadful Caribou, a lone princess from Equestria, Princess Twilight Sparkle and the faithful captain of her Dusk Guard and friend, Tempest Shadow, stood over a set of seven orbs of unknown origin. But the only one of the two mares who knew of the orbs' real purpose and what they could do was Twilight. Long ago, shortly after she became a princess but before the Caribou came, she had saved the life of a young human male on a world completely different from the one she had been to three times. This world was riddled with war and strife amongst the human population, but she saved the life of the young man once before, then met him again, though she was invisible to him and everyone else around him. But he always knew she was right there, and he would talk with her. And whenever he was upset, she would comfort him with her mind, and it was as if he could hear what she was saying. But shortly after she had to return, and because of this she was sad of leaving a friend behind. But he swore a promise that one day he would come to Equestria under his own power someday to see her in person. But to this day, he has not arrived, and she was becoming desperate, not because she wanted to see him again, but because of the war against the Caribou and their sick and twisted views on the dominion of their race. They have been using the females of the kingdoms they have subjugated as breeding stock, the males raping the females, whether they were family, spouses, or random strangers.

“Are you sure this is gonna work, Princess?” Tempest asked, unsure that these orbs would work, which had from one star in one orb numbering in numerical order to seven stars in the last orb. “We don't even know what these orbs can do, let alone where they came from. How can you be sure about what they'll do once you've activated them?”

“Because I know what they are and what they can do, Tempest.” Twilight said, replying to her faithful captain and friend since after the invasion of the Storm King. Tempest became captain after Flash Sentry died in the defense of Ponyville after he was transferred from Canterlot, and she had helped immensely with organizing the refugees to the safezone where the Castle of the Two Sisters still stands in the ruins. “As hard as it is to do so, just trust me on this. It's no coincidence that they appeared out of nowhere in the refugee safezone as if they were meant to be found by us, and a voice told me to use them away from prying eyes. But from what I can sense of their magic, there is only enough power for one use, after which they will be gone forever. Like whatever is inside them knows what the Caribou have done, and doesn't want the power of these orbs to fall into their hands. Please, Tempest, if you've ever trusted me before, trust me now.” Twilight looked into Tempest's eyes, a pleading look in them. Tempest had that same look before, when she saved Twilight and her friends from the final ditch attack of the Storm King which resulted in his ultimate demise. Tempest looked determined before nodding.

“Alright, Princess, I trust you.” Tempest said, placing a hand on her friend's shoulder. “Let's get this over with before they disappear without using them.”

“Right. Here goes nothing.” Twilight said, with a smile, turning back to the orbs, which began to glow brighter and pulse with light faster as if in anticipation of the words that Twilight spoke next. “Eternal Dragon. By your name I summon you forth to grant my wish. SHENRON!”

As if the chant Twilight said were the magic words, the orbs began to glow brighter and brighter until there was an explosion of light and a massive roar that Twilight and Tempest needed to close their eyes and cover their ears. When the roaring was gone and the light had died down save for what still emitted from the orbs, Twilight and Tempest stood there in complete awe and slack-jawed in shock.

Right above them and looking down right at the two of them, rising out of the orbs themselves, and coiling about in the sky, was a massive green dragon, with green scales, a yellow underbelly, and two brown horns coming out of it's head. But the feature that was drawing the mares' attention were it's glowing red eyes. But Twilight felt no evil, no malice coming from the dragon, just a no-nonsense type of feeling from this dragon.

“I AM THE ETERNAL DRAGON SHENRON! I WILL GRANT ONLY ONE WISH TO THIS WORLD AS I WAS TOLD TO DO WHEN SUMMONED BY A PRINCESS OF EQUESTRIA! SPEAK YOUR WISH NOW SO I MAY DEPART THIS WORLD FOR MY OWN AWAY FROM THE EVIL THAT PERMEATES HERE!”

Clearing her throat and standing in a regal manner like her former mentor and fellow Princess, Celestia, would, despite the fear she felt, Twilight stood in front of Shenron and looked him in the eyes, saying, “Almighty Shenron, please help us. Our world has been ravaged by the Caribou, the evil you mentioned that permeates my home.” Twilight said, her emotions started to break free and tears falling. “They have taken everything from us, subjugated every kingdom that they have conquered and have enslaved and killed countless innocents.” Twilight stopped and stood silent for a few moments, crying from the bottled up emotions she had held back since the beginning of the war. When she calmed down enough, she looked back at Shenron and said, “So I make this wish. Give us a strong ally, somepony with the kind of power to help us defeat the Caribou and help us defend Equestria and our allies who have been subjugated. This wish I ask of you, Almighty Shenron!”

Shenron just looked at Twilight with an unchanging look as he ‘hmmmm’d’ while he thought about the wish she had just asked. Twilight and Tempest stood there, anxious at what Shenron would do as to what Twilight asked for the wish. Then, to their relief, he finally spoke.

“THERE IS NO ONE FROM YOUR WORLD, PAST OR PRESENT, WHO IS STRONG ENOUGH TO FACE OFF AGAINST THESE CARIBOU OF WHICH YOU SPEAK,” Shenron said, causing both Twilight and Tempest to look down in sadness, thinking that this was all for nothing. “BUT I KNOW OF SOMEONE FROM A DIFFERENT VERSION OF MY WORLD WHO WOULD BE MORE THAN WILLING TO HELP. AND I BELIEVE YOU KNOW THIS YOUNG WARRIOR, PRINCESS.” When Twilight heard that last sentence from Shenron, she had a hopeful look in her eyes, knowing full well whom Shenron Spoke of. “HOWEVER, TO BE ABLE TO HELP YOUR WORLD COMBAT THE CARIBOU, HE WILL HAVE TO BE DIFFERENT, CHANGED, IN A WAY THAT MIRRORS SOMEONE FROM AN ALTERNATE VERSION OF HIS WORLD THAT HE HAS ALWAYS ADMIRED FROM A VIDEO GAME, DUE TO WHAT I SENSE OF HIM BEING REINCARNATED FROM A POWERFUL WARRIOR. BUT WHO HE IS AND HIS MEMORIES, INCLUDING HIS PROMISE HE MADE TO YOU, WILL REMAIN INTACT. ARE YOU CERTAIN OF YOUR WISH STILL?”

“Yes, Shenron, please. Anything that would help him to help us defeat the Caribou, as long as he remembers everything, like you said.” Twilight said, becoming anxious, but also hopeful for the first time since the war.

“VERY WELL, YOUR WISH IS GRANTED!” Shenron bellowed as his red eyes began to glow even more red.

While Shenron was granting the wish made by Twilight, both Twilight and Tempest were both grabbed from behind by Caribou slavers. They both tried to scream until rags were placed over their mouths, after which they passed out. The Caribou slavers used chloroform to knock them out, after which they placed inhibitor rings on both Twilight’s and Tempest’s horns. After they were both tied up and gagged, the leader of the slavers walked up and looked at the orbs with glee, chuckling with a maniacal chuckle that would make anyone get chills.

“Great work boys,” The leader said. “Our spy in the safezone did good for us, especially with the info on these wish orbs.” The leader then outright laughed maniacally and said, “With these, we can ensure the dominion of our race for eternity all in the name of King Dainn and the Crystal Cock.”

But before the slaver leader could utter a single word for the wish he mentioned, a bright white light on the ground blinds them…

When they uncovered their eyes, nothing was there. But what happened next shocked them to their core, as they were too late.

“YOU HAVE MADE YOUR WISH! I SHALL NOW LEAVE BACK FOR MY WORLD. FAREWELL AND GOOD LUCK TO YOU, PLANET EQUIS!” Shenron said as he retreated back into the Dragon Balls, after which they just shot into the sky and disappeared, never to be seen again.

The leader of the slavers was seething in anger until he stormed up to the bound Twilight and grabbed her by the hair on her head, yanking her up to her feet. The forceful action jolted her back to consciousness and she looked around, scared out of her mind. The slaver leader was in her face right at that moment.

“What did you wish for, slut?” The leader asked, barely holding his anger in check. When Twilight just looked at the slaver leader in defiance, he screamed, shaking her violently, “ANSWER ME!”

Despite her fear, Twilight still held her defiant look. When the slaver saw he was getting nowhere, he pulled a knife out and held it to her neck, this time causing Twilight’s look to falter dramatically, knowing what was about to happen. Yet she still held firm, not saying a word, despite her fear now evident on her muzzle.

“Fine then,” the slaver said, “if you won’t tell me, then I’ll kill you after I’m done toying with you for ruining our plans for those orbs.”

Before the slaver could begin doing anything, he was stopped by a voice filled with such rage, it made him nearly mess himself right there in fear.

“I wouldn’t do that if I were you.”

When the entire squad of Caribou looked out to the source of the voice, they saw a green armored biped, with a helmet on. On the helmet was a blue visor that was barely see-through, spikes on the forearms of the armor, what looked like a retractable blade on the right wrist, and a tubular device on the left shoulder. The entire squad of Caribou stood shaking in fear at the predatory feeling coming off this unknown person and the air of dread that was radiating off of him.

“Wh-who are you?” the leader of the slavers asked, definitely messing himself in fear right then and there.

The unknown creature, whose face they couldn’t see, just cracked his neck to the left and right. Then he cracked his left knuckles and then his right. The next seven words he said made all the Caribou in the squad soil themselves as they knew that what happened next, they brought upon themselves.

“Rip and tear, until it is done!”

Author's Note

I know Shenron appears, but his reason for appearing will be explained, as I plan this as a Doom/MLP crossover. I hope you all enjoy.
