Rise Of HellHunter

Rainbow Dash POV

“Ugh my head… what happened?” I sat on my flank and rubbed my head. “Oh right… high speed crash with Lightning Dust… I should be dead but it looks like I’m…” my eyes adjusted and I saw imps walking towards me. “Dead… I’m Dead, and I’m in Hell{1}. I think that they think of me as a tasty snack…” the imp closest to me stepped out if the way to let a giant muscly bipedal skeleton figure with a giant… WAIT IS THAT A LASER AXE?!?!?! OH I’M SO DOOMED!!! I closed my eyes and waited for the inevitable… but I opened my eyes after I heard a series of loud bangs. What I saw was easily the scariest and most awesome thing I’ve seen in my life… or is it afterlife now that I’m dead?

Anyways the giant laser axe wielding skeleton was fighting a green metal golem with an array of long ranged weaponry, that was easily tearing apart the imps with it’s bare hands, which is AWESOME!!! Anyways the skeleton brought down the axe and the golem got out of the way… that’s when I noticed that it wasn’t a golem, but a human{2}! I could tell it was a human by the tan skin that was exposed, I met a mythical creature in Hell! If we were anywhere else I would’ve passed it off as a prank, but I was in Hell, so it wasn’t too surprising. The human ripped off the giant skeleton’s head and looked at me. He then marched towards me, forcing me to back up until I was pressed against a wall. After he was over me, he extended a hand towards me, and after accepting the fact he wasn’t going to hurt me, I took it. He pulled me up to my hind legs, and then I got back to standing normally.

“What’s your name?” He said, I replied and he chuckled a bit. “I’m the Doomslayer… and if you want to scare the ever living shit out of the demons down here, you’re going to need to adopt a better name. Sure you can use it for normal occasions but when ripping and tearing, you’ve gotta get a new name.” I took it in and acknowledged it. “Good. Now let’s get you some armor and teach you how to use a gun…”

Doomslayer’s POV

We walked into the stronghold guns at the ready. I held my trusty double barreled shotgun, and she had her trusty ballista ready. Her ballista was connected to her back in between her wing joints. It was high enough above her to be able to shoot normally, but it also allowed her enough mobility to keep up with me. Plus she could be used as a little ballista cart, which is nice. I also gave her augmented strength, speed, perception, yadda yadda yadda. Point is, we were taking back the stronghold and reviving the Night Sentinels.

Her Invictus suit{3}, protected her from a fireball an imp threw, who was quickly snuffed out by me. She sped ahead of me and fired a bolt into a baron of hell, who promptly exploded. I pulled out my updated Chaingun and switched it to Mobile Turret Form (MTF) and wreaked havoc among the demons while she switched to her plasma rifle and dive bombed the demons. The two of us kept going, wiping out demons and fortifying the rooms we cleared. Eventually all of the rooms that didn’t really serve any real purpose but for travel were cleared and fortified, locking demons in rooms and denying the demons on the lowest floor access to the top floor.

We cleared out every room except for the bottom one and I thrashed an old lady, who would then get her vocal cords cut by Dash. The only room left would be the throne room but we decided to clear out the bottom floor. Soon afterwards the prison floor was cleared and all that was left was the throne room. We opened the door and a few Night Sentinels{4} attacked us. Here we resorted to incapacitation, so we knocked out the ones attacking us as Dash stepped up to the throne.

“Why are you here?” A raspy voice said. She opened her mouth to speak but nothing came out of it. I grunted and no sound escaped my lips… the room was getting rid of all sound except for the speaker. A pale blue man then sat on the throne and spoke.

“What you interfere with now is bigger than you can imagine.” Rainbow looked like he wanted to strangle him, but couldn’t. “If you continue, you will bring down the heaven’s WRATH!” Images of equestria on fire flashed through Rainbow’s head and mine. “It is Written.” I saw Rainbow being chopped up and turned into a cupcake by her friend. “It is their time to give penance.” Rainbow was in obvious distress, and that pissed me off, I tried to move but couldn’t, we were stuck. “You are but one man and mare.” She screamed but nothing came out of it, she was screaming in fear and anger. “THEY are no longer your people to save.” With that he disappeared and all sound resumed, alongside our movement.

She rushed at the throne, which was no empty, with a rage filled yell emanating from her throat. She slammed into it as the Night Sentinels awoke. They looked at Rainbow and rushed to her. I was about to kill them when I saw them applying first aid to her wounds. After explaining what happened, they thanked us for clearing the stronghold, not killing them, and expressed their rage at the Heavens setting fire to Rainbow Dash’s home. They swore their allegiance to us and when I asked where the other Night Sentinels were, they said they didn’t know, but would go out to find them. I suggested they get equipped with guns and said me and Rainbow would assist if there were any home defense systems in place for the stronghold.

“Well there sure are mate, but we could use a few more.” This Night Sentinel’s name was Charlie, and he had an Australian accent. He was apparently the medic of the tiny group of the Sentinels that were left, and the one who felt the most rage at the heavens for their heinous crimes. “Just press the console in the room next to this one and that’ll activate the Stone Sentinels{5}.”

I did exactly that and they rumbled to life. I then got healed up thanks to Charlie while Rainbow helped Dimitri, the engineer, make the escape pod able to hold five people and make it space worthy. After that we got in and we were ready to fly. “Let’s do this…”

Author's Note

Despite the rapid progression in this chapter, this story WILL be longer. Anyways Footnotes!

{1}: Tartarus is not the Equestrian Hell, but a complex prison built by Celestia and Luna named after the Greek version of Hell due to the amount of monsters it could hold in its walls. Ponies who have done bad things in life still go to Hell when they die.

{2}: Like how talking Ponies, Unicorns, Pegasi, and Alicorns are mythical in our dimension, Humans are mythical in theirs, hence why the Doomslayer was called a mythical creature.

{3}: The Invictus suit, AKA the Unconquerable suit, allows Rainbow to switch between weapons and it still keeps her agility, by being aero dynamic and having boosters on the wing tips.

{4}: a few Night Sentinels did survive the massacre by hiding out in the throne room, but when the Heavens interfered, they were brainwashed into destroying anyone who enters the throne room. The sentinels consist of Charlie, a Night Sentinel medic with an Australian accent, Dimitri, a Night Sentinel Engineer with a Russian accent, and Peterman, a Night Sentinel scout with a Bostonian accent.

{5}: The Stone Sentinels are statues of the Night Sentinels imbued with Argent Energy. When not active they just act like statues but when activated, they will act like golems and protect the stronghold.

Rainbow Dash’s Log: UAC Space Station

Rainbow Dash’s POV

The pod flew quite nicely, and I was still confused on how Dimitri got the necessary materials for updating the pod… I think I remember pinkie telling me about something called plot exposition… certainly would explain a lot. I still can’t get over the fact that my home is burning… and that it’s the Heaven’s fault. Why would they do such a thing? It’s horrible, I just hope my friends are ok.

“Vis place is in lots of disrepair. Vis place would take millennia to fix.” Dimitri said as we flew past a red barrel. Dimitri turned the pod around and docked it in the spot it was originally launched from. We came out of the fucking pod like it was a clown car, and while it looked small on the outside, it was as large as 500 company warehouses on the inside… gonna chalk that up to plot exposition. I remember asking Dimitri about it and he said something along the lines of “Don’t question it or you tiny little pony brain will explode.” Although it was much more… Russian.

“Still can’t get over the fact that this tiny little pod is as big as 500 warehouses on the inside yet it can fit in this pod bay.” Apparently I wasn’t the only one. Peterman was confused too, but after deciding to forget about it, we started ripping up the station. We took an entire chunk of the space station and put it inside the “escape pod” for updating the stronghold’s defenses. In fact we just decide to TAKE THE WHOLE STATION WITH US which we ACTUALLY MANAGED TO FIT IN OUR POD!!! I mean I’m not complaining about all the new defenses and base materials but what I AM complaining about is how the out the station INSIDE THE POD. I should probably stop thinking before my head explodes…

Anyways we fixed up the space station while on our way back to the fortress and decided to connect it to the base VIA magic or something. Look what I’m trying to say is that they’re gonna stick the station onto the stronghold and fuse them together… god damn it I sound like Pinkie Pie. Is this what she’s always so excited about because I seriously don’t know. Is this why Violentlycan? Yes I can break the fourth wall get over it. Anyways they’re talking about some shit I don’t understand so I’m going to take a nap, I’ll see you at the Stronghold. Also author sends his condolences about the very short chapter, he’s just doing finals right now as he’s writing this so yeah… get over it. Peace.

Author's Note

Yes I am taking finals and she CAN break the fourth wall. No joke. Anyways gotta go. See ya in the next chapter, which will be considerably longer to make up for the short one.

Third Person (No POV):

The Doomslayer finished loading all the weapons and giving them to the Sentinels. It has been five days since he found Rainbow Dash, four since they retook Sentinel Prime, and three since they merged the space station to Sentinel Prime. He then got a blip on his radar. Something entered Sentinel Prime. He cocked his shotgun and rallied everyone to his location. Within an instant, Charlie, Dimitri, Peterman, and Rainbow Dash were ready to handle the intruders. After a few instructions, they went to fight the intruder… oblivious to what was going to happen…

Doomslayer’s POV:

I fired my chaingun wildly towards the horde of Flood spores and Flood Infected Sombra forces. The automatic turrets did their jobs with frightening accuracy, but the two combined opposing forces were overwhelming. All of the Night Sentinels that arrived after merging the space station to Sentinel Prime and were revived kept firing their plasma rifles, while some snipers tried to take out the leader of the assault. The leader looked like Rainbow Dash but with King Sombra’s eyes and the teeth of the Gravemind. Juggernauts lurked behind her, their footsteps thundering on the main bridge of Sentinel Prime. Soon I pulled out the BFG9000 and fired it, causing considerable damage, but not enough. Sentinel Prime was going to fall again… and It’s all my fault…

“THEY are no longer YOUR people to save.” NO!!! SENTINEL PRIME WILL NOT FALL TODAY!!! NOT WHILE I’M ALIVE AND KICKING!!! I run into the horde rip through their forces, determined that to find the source of their unlimited troops and put an end to it. Soon enough, I see two portals leading to two different Equestrias… I have to end this… ONCE AND FOR ALL!!!

I jump through the portal where the Flood spores are coming from and appear in a flood infested Hive of sorts. Changeling combat forms spot me and run at me, flood infection forms following. One infection form jumps onto the exposed part of my arm and tries to infect me from their, but the argent energy barrier around me vaporizes the infection form. I continue to rip through the hive when I spot Rainbow Dash about to be infected by a flood infection form. I whip out my plasma gun and vaporize it, pull her up, give her the plasma gun, the mark of the Doomslayer, and an argent barrier to protect her. “GO!!! RUN THROUGH A PORTAL AND INTO A GIANT STONE TEMPLE WHERE PLASMA AND BULLETS ARE ERUPTING FROM IT AND GIANT STONE STATUES ARE SMASHING JUGGERNAUTS!!! I’LL GET YOUR FRIENDS TO DO THE SAME AND I’LL GET RID OF THESE BASTARDS, THE FOLLOW YOU!!!”

She didn’t say a word and just ran, plasma erupting from the gun’s barrel vaporizing the flood forms. I run through the giant mass of flood and run nonstop, determined to get her friends through the portal and blow the flood to bits.

Third Person (No POV):

Twilight sat at her desk with a picture of Rainbow Dash on it. She wept as she remembered the sacrifice she made when Celestia yelled to Twilight that they have company. Twilight growled and bursted from the door, ready to shoot any flood form, when the Doomslayer arrived, equipped the Mane Six, Starlight, Trixie, the the royal sisters with guns, a mark, and a barrier of sorts. He then instructed them to follow him.

When Twilight, halfway through the trip stopped the Doomslayer, and accused him of trying to get them killed, he explained that Rainbow Dash was alive, and being protected by his people. He also said he was going to destroy the flood. At that they got energized again and ran towards the hive, Doomslayer leading the charge.

Doomslayer’s POV:

I lead the charge as the hive quickly fell as we ran through the halls, leaving behind destruction in our wake. I pulled out my BFG9000 after everyone was through and fired it at the core, wiping the flood out from Equestria. I ran through the portal and it closed, after a while only the Sombra forces remained, and I ran at the portal leading there.

After a while I came back to all the Equestrias I freed and returned their inhabitants after they helped me build a dimensional rift creator and helped me take out the leader. I sent them home and was about to call it a day when three celestial objects crashed on the bridge. One was a battle worn Princess Celestia, and another was a battle worn Princess Luna. I helped them up and got them inside when I heard a roar. I spun around to see a white heavenly metal angel with orange wings rise up and fly. This was going to be a long fight…
