Sasuke's Weapon of Victory

Omnitrix

Sasuke Uchiha and Naruto Uzumaki were at the Final Valley, standing on the top of their respective incarnations. Sasuke on the top of Madara Uchiha, while Naruto was on top of Hashirama Senju.

They were done with the war against the revived shinobis, the Jinchurikis, the Tailed Beasts, Obito, 10 Tails, Madara and even Kaguya Ootsutsuki, and now they were standing to see who will win and who will prevail at the final battle as they had their little discussion at how both of them will change the world. 

Sasuke would do it by force, eliminating the 5 Kage and shouldering all of the hate of the Shinobi World, creating peace in his mind, while Naruto would do it by uniting the 5 Great Nations in peace. 

He knew that this wasn't going to be easy, and the fact that he had his Rinnegan + an Enternal Mangekyou Sharingan, with the combination of Hagoromo's chakra while sealing the 8 tailed beasts, and a half of Kurama. 

But before they could go at it, Sasuke looked at Naruto, "Naruto, before we start, I have something to tell you. Something that will give me the win of this battle." he said as Naruto raised an eyebrow at that. 

Naruto didn't like the sound of that as he looked at him in interest, "What is it?" He was expecting to do something bad, like him having even a Byakugan, but he highly doubts he could have something like that. 

Sasuke looked at his right hand, "It is something that I didn't know that I had, until I was on death's door, like you Naruto, something that has been in my possession ever since I was born when I was Indra Ootsutsuki." Naruto raised an eyebrow. 

"Uh... say what?" asked Naruto as Sasuke began taking off the black bracelet. 

"It is something that the Sage Of The Six Paths told me during my past life as his son, as he told me that it also came to our world with Kaguya, a small device that fits around my wrist, coming from space from a different life form in order to create peace around the world." he said as he took the bracelet off. 

Naruto looked at him, dumbfounded by what the Last Uchiha told him, "Okay, you lost me. What are you talking about?" 

Sasuke sighed, of course the loser doesn't know what he is talking about. He could've known if he had his memories when he was Ashura when he fought him while they were young. 

He raised his wrist to reveal a small watch of some sort, that had green lining on the top of it that was like an X in half with a black colouring below, as they went down with everything around it being white. 

Naruto looked at it and widened his eyes, but not for the reason he might think, "You are going to win... WITH A WATCH?!" he said shocked that he would be so confident with using a watch of all things to win a fight. 

Sasuke sighed. "No, you idiot. What I have is the most powerful weapon in the Galaxy, a weapon that I got from The Sage Of The Six Paths while I was dying, a one that changes my DNA temporarily. It is called... the Omnitrix." he said. 

"The Omni-wha? How does that thing even change your DNA?" asked Naruto as Sasuke darkly chuckled. 

"How about I show you?" he said as he pressed on the dial, making a small disc showing all of the aliens he had as he stopped at a specific one, making the dial open up to reveal a button of some sorts and he then slammed it, making him turn into Four Arms. 

Naruto realized what this meant. He looked astonished by the look of it and even the thought of him having more than that both terrified and excited him. 

"So?" asked Four Arms as he cracked his knuckles, "Ready for the Final Battle?" he asked as Naruto grinned. 

"You betcha!" he said as both of them jumped from the heads of Hashirama and Madara. 

It was a one sided duel. Naruto was outclassed in everything he could've done. Four Arms was slow, but dealt massive damage for every hit he made, making it better for him to just dodge the attacks rather than block it, Kickin Hawk was a master of Taijutsu, countering every move he would've made with Taijutsu, and even dodged a barrage of Shadow Clones while using the Rasengan at the same time. 

When he was getting his ass kicked on the ground, in the air, it was the same thing. Astrodactyl was flying around with Naruto with his whips, smacking him all over the place as he threw him as hard as he could, while then transforming into Jetray, catching him in the air, but then slamming him into the ground as fast as possible. 

Not to mention, he was outclassed in long ranged attacks. Heatblast was quick enough to create fire hotter than his Magma style: Rasengan, Big Chill created massive pillars of ice, Diamond Head was making sure that he didn't get even the slightest bit of damage even with him using the Rasengan. 

Even when he could hit him with a Rasengan, it was useless. Chromastone and Feedback were able to absorb the Rasengans and even shot them back, with Upchuck even eating a Rasenshuriken and throwing it back towards him, making him dodge it. 

When he brought out his Sage Jutsu, the same one that he used against Pain, it didn't even matter as Humangasour grew 6 times his size and was trading blows with Naruto. Even Chakra Mode form wasn't enough as Gravattack was using his abilities to throw Naruto around, making him unable to try even the slightest move. 

When he finally brought out his Ashura Mode, he thought that nothing, nothing can go against this, but he was wrong about that as Sasuke turned into Way Big which was the same size as the Ashura Mode, and they began throwing blows and after another, as after a few minutes later, Naruto got out enough Sage Jutsu from a clone, as he created 2 Tailed Beast Bombs Rasenshurikens, but Way Big created a beam of light as he crossed his arms together, clashing with the Rasenshurikens, creating a massive explosion, destroying the Madara and Hashirama statues. 

Kakashi Hataka and Sakura Haruno could only watch in disbelief from the explosion as they could hear only one voice from the explosion which was Naruto's scream as Sasuke turned into a Celestial Body that was that of a god, Alien X, not without a single scratch on him. 

Alien X floated towards a down Naruto as he didn't have the strength to even move his arm. He stared at Alien X's face and could see nothing, but pity for the poor soul that went against him in this battle. Alien X could only stare as he thought about killing his one and only friend he ever had. 

He then blinked, making Naruto feel like he was turning into ashes as he could only stare at Alien X with a weak smile. 

Sasuke de-transformed from Alien X as he could only stare at the ash of his one and only friend. He looked at the Omnitrix and covered it up, only using it when he doesn't have enough Chakra to finish the job and for real threats. He looked at the sealed Tailed Beasts and smiled. 

The time for his revolution has begun. 

A/N: Yeeeaaaahhhh, I created this only because Sasuke shares the same VA as Ben Tennyson, and I just had to create this. I hope you enjoyed the fic.
