“Twilight’s Twinlight” belongs to Autumn Breeze and “Halo: Celestium” belongs to Free shavacado. Check out their stories and know these stories I’m referencing are NOT MINE, and they are NOT OFFICIAL, they’re just references that will introduce new characters and will begin the Doomslayer’s mission to save ALL Equestrias.

Celestial Justice

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…
