(Y/N pov)

You stood in your armor at the front of Korra. You smiled darkly under your helmet while Bolin and Rivin where on their knees trying to get up. You looked at Korra your eyes glowed blood red.

Y/N:*Demonic* I....I..now have over ten thousand lifetimes of Knowledge now within me...I Now see how our species crawled out of the mud...How it was vaatu who broke the divide That separated the spirits from the Mortal world...Now...to hate me is to give me breath...To fight me is to give me strength...Now prepare to face your destruction!!!

Korra: I'm not going to let that happen y/n.

Y/N: You are powerless avatar. You don't have your bending and now you will watch everything you love be destroyed!! *Steps and raises fists and bursts black fire at korra*

Korra: *Tries to block with water but fails. She gets burned badly* Gahh!!

Korra got blasted and hit her back on a large rock. She had burns on the side of her arms.

Korra: Ah...

You walked away from her and headed towards the spirit portals to get back to the mortal world.

Y/N: I am Superior to you in every possible way Avatar.

While you where walking something hit the back of your helmet. You turned and looked it was Bolin he was throwing rocks at you.

Y/N: *Annoyed* What are you doing now.

Bolin: I'm not done with you!! You are going to give me back my brother!! He's still in you!!

Y/N: Then you will die In denial. *charged directly at him*

Bolin took a stance and raised some massive boulders to try and hit you with them. You jumped and had flames shoot from the bottoms of your feet at Bolin.

Bolin surrounded earth around his body to protect himself from the flames.

Y/N: Your friends can't help you now. Humanity will be slaughtered and upgraded by me. And three will die here. You. Are all. Alone.

Bolin: No! I'm not alone!! My brother is still in you!! He will help me!!

You looked annoyed under your helmet but something happened that completely shocked you. Mako took control for a split second.

Y/N: *Mako* Bolin!! Stay strong!!

You then stopped him and took back control.

Y/N: *Pissed off* Fools!! You can not stop me!!

Bolin charged at you and kicked you in the stomach sending you back.

Bolin: I can try!! *Threw several boulders*

Y/N: *Raised hands and shattered boulders to pieces* *Darkly chuckles* Ha-Ha-Ha-Ha.

Bolin raises up the ground you where standing on and continued to through boulders at you.

Bolin: *pleading* Fright mako!!!

Mako then managed to take control again

Y/N: *Mako* Bolin!!....

Bolin: *Throws boulders* Fight him!!

Mako continues to manage to get stronger. You keep on trying to fight him.

Y/N: *Mako* You..will not take!!!....

Bolin: Fight him!!!

Y/N: *Mako* My....Brother!!!...

You got filled with rage and in your subconscious you grabbed mako and erased him from existence silencing him once me for all.

Y/N: Your....Brother is.......GONE.

You then summoned all the rage with in you and blasted Bolin completely back with your flames. He grunted in pain and passed out.

Y/N: *walks away darkly chuckling*

You walked over to the spirit portal and raised your hand up. The portal then sucked you in and carried you back to the mortal world. Leaving Korra, Bolin, And Rivin behind.

(Meanwhile)

Azula was fighting against troops outside of the spirit portal, while she was kicking ass like usual she looked up and saw a large energy mass leave the spirit portal and to somewhere else.

Azula: He's Done it, return to the ships! We no longer have business here.

Marist: *Inside his mech he had Kai in his hands about to rip him in half* Awww....Do we have to right now?...

Azula: NOW!!

Marist: *Mech* Fine. *He throws Kai off into the snow*

With everyone taken care of Azula and the others head back to the ship to return to Republic city

(Y/N pov)

You stood at the edge of the ice near the ocean water, your face looked cold and inexpressive under your helmet. You turned your body as you stared at your troops and Azula.

Y/N: Today is the end of republic city. The end of a regime that acquiesces to disorder. At this very moment the four nations lie to the citizens! While secretly planning to build armies once again to over throw each other! This fierce army where we stand untied together will bring an end to the governments, to there cherished armies. All remaining nations will bow to the Foot Clan! And will remember this as the last day of the four nations!

The soldiers then held there arms out to cheer you as you tired your body and raised your right arm shooting energy from it forming several portals in the sea that would lead them to Republic city.

Y/N: Go fourth and conquer! Leave every part of the city to ashes and kill anyone who crosses your path.

You then clenched your fists as you exhaled fire from your fists using them as a jet engine of sorts to make you fly, normally only sozins comet could make firebenders fly. But with the fusion of vaatu and raava this fusion strengthened your bending allowing you to become stronger than you could have ever imagined.

You flew into the largest portal as you had finally arrived in republic city on the doc's where other ships where at. Soon after a few minutes your fleet of war ships appeared behind you. You walked on the doc's in your armor as you began to change. You began to cough up dark colored blood and your limbs started to stretch out in painful ways.

Your arms and legs stretched out and your torso began to grow much larger and your body armor began to grow larger but started to weld into your bodies skin. The armor's color turned from dark silver to ink black and the blades turned blood red, then tendrils began to burst out of your back and form into blades. The final touch to your new form was a large red and orange symbol that being similar to vaatu's symbol. You stood up and looked down at republic city.

*STOMP!!*

*STOMP!*

Y/n then began laughing Demonically

Y/N: I was trapped in that pathetic mortal body....Then I was trapped in the digital universe! Now...I am free! Bow! To your Lord and Master!

A/N: I have to thank my good friend Riddler478 for making this artwork for me. Thank you Amigo.

(No one's Pov)

Y/n then walked through republic city as he began to set everything up in flames, He opened his mouth pieces in the bottom part of his helmet and began to spew out black flames of death across the city. He Began to wrap his tendrils around buildings and ripped them apart to pieces.

While Y/n was doing his own thing on the north side of Republic city his troops walked through the streets in there Mech's evacuating people out of the city, Marist leaded his troops of Equalists in there Iron Monger suits. Taking people out of there homes and putting them on boats in the shore and pushing them out into the ocean. Marist was having the time of his life just shooting people and using the mechs strength to rip some peoples heads off.

While Azula wasn't happy with Marists tactics she just let him do his own thing while she burned homes and buildings. Y/n then looked out and saw Aang's statue on his memorial.

Y/N: *Raises right arm* Peace has died with you Avatar Aang.

He then blasts an enormous amount of black fire towards the islands statue and completely blew up/melted the entire statue to the ground. As soon as the son was setting down on the ruins of Republic city, Y/n watched up from his height from a far the amount of destruction that he has caused across the world. He smiled mischievously under his helmet as he watched the city burn up in flames.

Y/N: Such...Beauty in chaos.

*Time skip*

(Marist Pov)

As I was walking up a hill in my mech where I was trying to look for y/n since he hasn't been seen in a few hours and his angry bitch of a wife was yelling at me to find him. As soon I reached the top of the hill I saw that it was a cemetery, not a single flame was seen in cite around the cemetery and it looked untouched. I then activated my rocket launcher on my right arm and aimed it.

Marist: Might as well.

Before I could pull the trigger and fire the mechs arm then got completely blasted off by a ball of fire. Seeing this I completely freaked out.

Marist: What the hell?! Who the hell did that?! Who the f*ck do you think you are?!

I looked around and saw someone in the middle of the cemetery wearing armor, I then inspected closer and saw it was Y/n. He had his helmet off and I saw his skin was now completely pale like, He almost looked like a corpse with red eyes.

(No one's Pov)

Y/N: Don't.

Marist: *Rolls eyes in mech and opened it and hopped out* Yesh, your so judgey. Whats with you? Why aren't you giant anymore.

Y/N: I turned back normal. Being that large made me very tired. I can only stay in that form for so long from now on.

Marist: *Mot caring to much* Uh-Huh...Good to know. Why are you here in this cemetery anyway?

Y/N: I'm visiting an old friend.

I then looked down at the grave that y/n was standing in front of, it had the name Dredge on it, Aka y/n's dead step brother.

Marist: Ohhh. Huh, when did they put this in?

Y/N: A few months ago. His family doesn't know it but I came to the funeral to pay my respects. Despite our differences...I feel like dredge was the only thing I could call as a friend.

Marist: Hm. I was hoping for something a little more juicy than that, now with republic city basically destroyed at this point it looks like all the excitement is over.

As I looked down at the Grave and me and Y/n sat in silence I was about to leave until I started to hear a small chuckle.

Marist: *Turns head to look at y/n* Hm?

Y/N: *Starts to insanely laugh* Heh...Ha...Ha..HAHAHAHA!!! Now everything in my way is gone! No Dredge, No Avatar, No Republic forces! And everyone still believes in me...It's only a matter of time before I get rid of Korra and the others!

Marist then saw y/n get on all fours and crawled on top of Dredge's grave as y/n laughed more insanely.

Y/N: What do you think of that Dredgey boy?!?! This is my perfect victory!! That's right!! I WIN!!

Y/N's psychotic smile then stopped as it then turned into a cold and angered frown. Y/N then stood up and looked at Marist.

Y/N: Did you say you have nothing excited to look forward to Marist? Well...I Promise that won't be the case. From now on...*He then picks his helmet up* I'm going to show you the creation of a new world.

Y/N then put his helmet back on and then left Marist alone in the cemetery. Y/n then returned to his tower at the center of the city where he spent his entire night alone with his Wife/dark mistress where they spent the night together and had spent hours of having sex with each other to "Celebrate" There great victory.

(Meanwhile)

While it did seem impossible Korra and the others managed to escape the southern water tribe just barely with there lives. Bolin, Korra, and Rivin where in the medical center underneath the ship. Tenzin was above the ship outside with Kai as they began to look out trying to think what they should do now.

Kai: So...have we heard any news from republic city.

Tenzin: No, it went dark a few hours ago. The last transmission said that they where under attack. We can only guess that y/n succeeded in his plans.

Kai: If that's the case...where do we go now exactly. What do we do?

Tenzin: I....I..Don't know. We are just going to find somewhere to get Korra and the others to medical attention. That's at all that matters after that then we can come up with a plan. With what I'm guessing y/n did to republic city...we can no longer go there.

Kai: *Nods* Tenzin...are you saying that we lost the battle.

Tenzin: *He pauses and then looks out at the sea* No...at this point. We have lost the war.

Tenzin and Kai then staid silent to each other for the rest of the night.

To be continued...
