Eternity Comes out tops:

"I think I'm having the same problems as Firest- i mean, omega" Rainbow said as she struggled to get off something

"Why?" Fluttershy asked

"My armour won't come off"

"I've had mine longer than yours, you'll eventually be able to take it off at will"

"I don't really think this situation can get any worse..." Rainbow negatively stated, as a orb of red lightning appeared in the middle of the room, as the magic dispersed, Firestorm stood there in front of them. Rainbow went up to him and looked in his eyes.

"How is that even possible?"

"It can't be him, firestorm is dead" Rarity stated

"He never died, he evolved into Omega" AJ shot back, Firestorm began looking at them, with curiosity and awe. Then, Omega came into the room.

"Firestorm?"

"YOU!" The young red Alicorn Growled, horn blazing.

"Storm, I presume you have many questions, but jumping into the future is no way to answer them!"

"Well what is then Alicorn? Huh?"

"Let time run its course"

"How far in the future am I?"

"Judging by how you look, I'd say two years."

"Gonna explain anything else?"

"Prepare for a great battle, Prepare for your end, and my beginning" The Alicorn said, firestorm then began charging with red lightning, his time jump was running out, he was about to say something before exploding in a blast of red light.

"And what the hell was that?" Rainbow asked

"That was me visiting the future, please don't tell me you said anything..."

"Well um... Rarity said something about his death" Pinkie squeamishly said, he went up to rarity and yelled at her.

"WHAT DID YOU SAY!"

"Nothing! It's just, we havent seen Firestorm for a year or so now..."

"I AM FIRESTORM! I AM HIM REINCARNATED!" He yelled, all the ponies were terrified of the Alicorn

"You aren't, Firestorm wasn't scary like you are"

"Fluttershy, It has been two years if not longer since noctuid killed my sister, and even less since my other siblings were killed in cold blood, I will not rest until she is dead, I'm incredibly hostile, all the elements are damaged, mine are unstable, and she seems to just brush off the most dangerous of magic, I have not found a school of magic more lethal than she is using, so CUT ME SOME SLACK!" he yelled at the Pegasus, she shivered, and went off crying.

"Now, where's noctuid..."

"How dare you yell at Fluttershy like that!" Rarity yelled at Omega

"Rarity... I have been searching for the last two years for an answer to our problems, and now I have it, now WHERE IS NOCTUID!?"

"Well while you were searching, Fenir and Turbo were killed, twilight became an Alicorn, and wasted canterlot, you are dealing with two powerful alicorns, who are nowhere to be found, they kill, then disappear without a trace"

"That helps me in no way..."

"So why did you come back then? And what's with the weird getup?"

"This rainbow dash, is Eternity, the most powerful light weapon ever made, this is what I spent the last two years trying to obtain"

And now you have to deactivate it

"Let me guess..."

You know who this is Doombringer...

Noctuid appeared sat at the throne, surrounded by other dark alicorns, with twilight standing next to her, now a powerful Alicorn.

"I'm not afraid to use these Noctuid, to end the world!" The elements of harmony gasped.

I wouldn't if I were you...

She clapped her hoofs and all the dark alicorns drew blades and put them to every elements throats.

Disable Eternity, or your friends die.

And on order, Omega relaxed and Eternity lost its luster, the master Alicorn cackled evilly

Now, leave, and don't come back!

"Caught this one running outside!" One alicorn shouted, as she walked in Fluttershy, holding a blade to her throat.

"You will never get away with this noctuid"

Oh but I already have, because your friends have one hoof in the grave already

She nodded to the alicorns and they slit all of the elements throats, they all perished in front of him, Loyalty, Generosity, Kindness, Laughter and Honesty, taken out in a flash. The blood trailed across the floor and touched his greaves, and the gold returned to eternity.

"You don't know about eternity do you?" He said, as he raised the five ponies into the air.

"Renewal!" he shouted as his Flankguard glew brighter than all armour pieces, and the gold enveloped his friends, and their cuts sealed and their eyes opened, and they landed on the ground softly.

"Thank you omega" Rainbow said, as she hugged the Alicorn.

"What's the deal with your armour sets?"

"It's a long story, for another day" Rainbow said calmly, Noctuid was starting to get just the slightest bit uncomfortable.

Get them!

"Erasure!" He yelled, and his Sabatons glowed brightly, and the six dark alicorns were bound to the ground with golden chains. He slammed the ground and they were wiped from existence.

Damn you Omega!

"Running out of ideas?" He said, as his Sabatons glew once again, and he locked noctuid in place. Atlantis then ran in, swept up a dark blade, and placed it to noctuid's throat, she winced.

Okay okay! I yield Doombringer! Just don't kill me! You wouldn't want to do that!

"Time!" and his Helmet began to shine like the sun, and he began charging with energy, travelling through time, every event happening around him, till he got to one particular year...

Echoes of the Past:

He stood in a nursery, of a small house, with a young unicorn filly in front of him, he had travelled through noctuid's timestream, back to when she was five years old.

"Hello" he said calmly to the little filly

"Hello mr" she said back

"Do you want to go on a little adventure?"

"What do you mean mister?"

"Come with me" he held his hoof out to the scared unicorn, she took it and he thrust her onto his back, and went back to his present...

"See this noctuid!" he showed her the filly on his back, her eyes widened

"This is what you once were! Now look at you!"

"Who is that scary monster Mr knight?"

"That's you Noctuid" the filly got really scared.

"I never want to become that"

"And you never will" He said, as his Chestplate shone brightly, and his Sabatons too. The filly rose into the air, and disappeared in a wisp

What have you done!

"I've erased your past self from time, you don't exist anymore"

Your evil!

"No noctuid, your evil..." he said, as she began to fade, part by part.

"Master!" Twilight screamed, Omega locked her in place and she writhed and screamed as she watched her master disappear from existence.

"Come back!" She screamed, omega just watched, void of emotion.

"I need you!" She continued to yell at her disappearing master, Omega then went up to her, Flankguard shining like a star, and flooded twilights mind with all the times her and Firestorm had shared...

"I am prince firestorm, and I'm sorry i didn't come through the portal fast enough"

"Um, how would you like to go to that restaraunt sometime?"

"Peace be with you your highness"

"These are dangerous angel, only a Chronomancer should use them"

"Well she says I'm powerful, but I don't think so"

"Course you are! Your the strongest unicorn in equestria!"

"This is who you are twilight, that monster tried to change you, she succeeded, but your lucky I showed you the light, come back to us" Omega said as he pulled away from her, she collapsed onto the floor, the elements rushed to her to see if she was alright.

"She'll recover" He said, as he turned to the dark cloud that was now looming over them

That vessel was only to focus my true power, now, since you were such a fool, I shall destroy this world, and make you watch as everything you love, crumbles under my might!

And the cloud branched off in all directions, cracking the earth, raising volcanoes, causing all manner of natural disasters, many died in seconds, the elements of harmony, Atlantis and omega watched as Equestria crumbled around them.

"Is this it?" Rainbow asked omega

"Yes rainbow, it is" He said calmly, as the golden armour got brighter

"Are you gonna stop this?"

"In this lifetime, we all die, in another, we live, for an eternity" Omega stated, he was now as bright as the sun, which was now burnt out in the sky, a light blue, equestria began to freeze, Atlantis came face to face with the golden Alicorn.

"Save us" She whispered

"I love you Atlantis" he said as he leaned into kiss her one last time

"I love you too Omega" as she kissed him, but was forced back by a burst of energy.

"I take on these elements. For in darkest night, in brightest day, NO evil shall escape my sight, ETERNITY'S LIGHT!"

The golden explosion erupted from the ruined canterlot, and reached all the way out to the ends of the earth,to the gates of Tartarus, to the sky lands, everything was enveloped in a gold light. Time began to rewind and Omega saw his entire life flash before his eyes, as he destroyed this world.
