A/N - I don't like doing the movies so I'll take a few filled arcs with my own twist to cover this time gap
Looking down in horror, Anko Mitarashi, Fox Kitsune's mother had received multiple injuries as she laid in his arms.
"Mom! What happened?" Fox cried out.
"Naruto... Why? Why did you attack me?" Anko muttered out with all of her strength.
"No, mom! I didn't mean to! It wasn't my fault!" Naruto cried out as he held his mother close until a black figure appeared around him.
"Who are you?" Naruto asked.
"I'm you." The figure said as it revealed to be an exact replica of the red head.
"That does make any sense. I'm right here." Naruto called out.
"No, I am you. At least, I'm the darkest bit of you. The hatred that was created by the people of Konoha. I simply eradicated everything and everyone you held dear. This was the only way to eliminate your weakness." The fake Naruto said.
Naruto started yelling as he held his mother tightly in his arms. Forming around him, a massive crimson aura took over as his body changed into a fox-like creature. He was yelling and destroying everything in sight.
"Fox!" Yelled a familiar voice.
Sitting up almost immediately, Fox's body was covered in sweet along with the tears running down his face.
"Where am I?" Fox asked as he looked around and saw a few familiar faces.
Sitting and standing in the room was his team, along with a silver haired man known as Kakashi with the code name of Fang, Itachi Uchiha with the code name of Weasel, and Yamato with the code name of Dog.
"Fox, you had a nightmare, is everything okay?" Yugao asked.
"I saw my mother. She was dying and I killed her." Fox said as he started to break down crying.
Yugao came to comfort her teammate and though he was an Anbu, he was still a kid. Everyone watched with a look of sadness at seeing the normally emotionless boy cry over the loss of losing his mother.
"Fox, before we left, I spoke with your mother. She is perfectly fine and once we complete this mission, we will return." Said Kakashi.
Fox gave a nod and proceeded to the bathroom where he cleaned himself up and prepared to complete the mission.
After fifteen minutes, Fox exited the bathroom and appeared as a completely different person. His eyes remained their slit and crimson color along with his darker whiskers and nails. Deciding to change his Anbu outfit, he wore two black arm sleeves that went up to his elbows along with removing his vest.
"Fox, are you alright?" Yugao asked.
Fox gave her a nod and strapped his sword to his back and the six Anbu members proceeded to raid the castle. Unlike before, Koto had called for his Snow ninja to stand guard. He was aware they would get through, he just wanted to tire them out a bit.
"Alright, I will take the lead and strike with my Chidori." Fang declared.
"Weasel and I will clear the way with our twin Uchiha Release - Fire Raging Dragons." Dragon said.
"I will remain as a supporter and when we encounter Koto, I'll capture him." Dog said.
"Great, then Fox and I will begin our own slaughter against these guys." Cat said.
The six Anbu nodded and had begun. Without any hesitation, Fox drew his sword and began his own attack which surprisingly, became in sync with Cat.
Fang wasn't holding anything back either as he charged at the multiple snow ninja and pierced through their chest with his jab of lightning.
Inside of his underground sector, Koto chuckled at seeing the Konoha ninja eliminate his soldiers. "You fools. They are a dime a dozen." Koto said.
The two fire dragons were burning through the different hallways of the castle to cover more ground instead of the team splitting up. Dog made sure to strike anyone that were able to avoid the initial attack.
When the six Anbu finished their invasion, Fox pointed out the stairs and before anyone could stop him, he charged downward.
"Come on, let's follow him." Car declared and everyone proceeded to chase after their red head.
Everyone arrived to find Koto sitting on his thrown with a glass of wine in his hand.
"I'm glad you could all come." Said Koto in his taunting tone.
Without hesitation, Fox charged at the man but was sent flying by his Ice Release - Icicle Wave which planted the boy into the wall. Both Cat and Shisui charged in with this down swords. Koto ducked the first slash from Shisui and kicked him across hi Ann stomach which sent him flying. Yugao proceeded to slash down. However, Koto side stepped and swept her feet before landing his elbow into her chest.
Using his teammates as a direction, Fanf charged at Koto with his Chidori though the Snow dictator was able to create a wall of ice that stopped the Chidori and punch Fang away. Even Weasel's Grand Fireball jutsu wasn't enough to damage the man.
"Don't you all see? I've absorbed chakra that has enhanced my body. I'm the perfect shinobi." Koto declared.
"kotoamatsukami!" Shisui yelled but was shocked to see it had no effect on Koto.
"Even the powers of the Mangekyou Sharingan fail to affect me!" Koto declared as he fired off a barrage of ice needles.
"Earth Release - Mud wall!" Fang roared and his team was protected by the barrage of needles.
"Haha! I remember now, you're Kakashi Hatske. The man who has copied over one thousand jutsu!" Koto exclaimed.
"This is looking messy. He's able to take on all six of us at once." Yamato said.
"We don't let up. Every shinobi has his weakness." Kakashi declared.
"Let's all strike at once. It might be our best bet." Yugao declared.
Yugao prepared her strikes by charging fire chakra into her blades. Both Weasel and Shisui prepared to launch a massive Grand Fireball. Kakashi was powering up his third and final Chidori. Yamato prepared to strike with all his might. Fox had currently been knocked out.
At once, the five Anbu struck together. Koto was sent flying into the ground which created a massive crater in his special area.
"We did it." Yamato said but found that Koto was walking back up to the group while laughing.
"Not bad Konoha. However, you'll need more than that if you wish to take me down." Koto said.
"Damn it, I've used about all my chakra." Kakashi muttered.
"Not me." Yamato declared as he began fighting with his Wood release though it proved to be no match for Koto's ice release.
"Itachi, summon one of your crows to inform the Hokage. This guy is on an entirely different level." Shisui ordered and at once, Itachi followed the commands.
"Come on! I want a challenge!" Koto shouted as he charged at Kakashi.
"Damnit it." Kakashi said as he drew a kunai and took his White fang defensive stance.
Kakashi managed to block one of the punches but before he could prepare a counter attack, Koto fired a barrage of ice needles into his chest which sent the copy ninja flying.
Shisui charged in with his body flicker and performed his Fire Release - Solar Dragon Bomb. In that moment, Koto was able to absorb the jutsu. While it further increased his power, Itachi and Yamato noticed and ordered everyone to attack at once. Koto laughed and welcomed the on coming attack. As he absorbed Shisui's fire ball, Yugao's fire slash, Yamato struck him hard with his Wood Dragon and Itachi with his Fireball jutsu which had somehow injured the man.
"That's it! When he absorbs chakra, he is defenseless! We need to keep up the pressure!" Yamato ordered.
"Haha! You fools! It's over! Ice Release - Glacial Explosion!" Koto yelled in the entire castle blew to pieces and they were brought outside where the snow covered everything. "It's over! I now have unlimited chakra! Even if you damage me, I can restore myself with ease!" Koto yelled.
"He's a monster..." Kakashi muttered.
"A monster? No, I am a demon!" Koto yelled as he continued with his sinister laugh until someone stood up.
"No, you aren't a demon." Fox said as he glared at the man.
"Oh no?" Asked Koto in a mocking tone.
Having crimson chakra surround his body with two tails sticking out, Fox informed him that he was a true demon. In a flash of crimson light, Fox appeared in front of Koto and delivered a punch to his chest which knocked the man back. Before Koto could respond, Fox appeared behind him and struck him in the back.
"Damn you kid. It's all for nothing! I can't be defeated!" Koto declared.
Fox chuckled as he charged once more and when Koto tried to use his Ice Release - Blizzard Wave, Fox appeared in front of him and delivered a massive uppercut that was followed by a heel to the top of his head.
Koto coughed up a small bit of blood "Not bad, but it's still not enough." Koto remarked while wiping his mouth.
"Kyuubi, I need more chakra." Fox mentally said.
"I don't think your body can handle it. It's very possible that it will kill you." Kyuubi explained.
"If I don't use it, we will all die here anyway. We need to use everything we have." Fox explained. Kyuubi agreed and began giving Fox more of his chakra.
Unlike before, Fox got down on all fours as the third tail was forming. This concerned everyone but knew it was their only hopes of beating this monster until reinforcements arrived. Fox's body became fully covered in crimson chakra and had given him a sadistic glare that was similar to Anko.
"Bring it on demon!" Koto yelled but before he could blink, Fox sent him flying away. The barrage of punches, kicks, and paralyzing roars that were given had heavily damaged the man. Even with his endless supply of chakra, he lacked the speed to react.
"Brat, I need you to perform the Tailed Beast Sphere." Kyuubi told his Jinchuriki who was busy with inflicting massive amounts of damage.
"Not yet. I need him to suffer and feel the pain he's caused others." Fox said.
Koto could only curse at his misfortune. A mere six year old boy with the powers of the strongest Tailed Beast of all had completely overpowered him and has inflicted massive amounts of damage.
Even Shisui's Sharingan had difficulties with keeping up with Fox's speed. "This is like nothing I've ever seen." Shisui commented.
Fox let out a roar before back flipping away before placing his hands together. Forming in the center of his hands, a black sphere with purple, red, blue chakra had appeared.
"You think that jutsu will work? I'll just absorb it!" Koto shouted as he prepared his absorbing jutsu only to be stuck absorbing Shisui's fire release along with Itachi's jutsu. Yamato jumped in as well and began releasing his wood release. Though it was powering Koto up, he was unable to protect himself.
Fox took the sphere in his left hand as he charged at the Snow dictator and connected the ball into his stomach which caused a massive explosion which could be seen everywhere in the Land of Snow. Yamato was forced to use his Wood Release - Wooden Statue Barrier to protect his fellow teammates from the blast.
Koto was yelling in pain as his body had begun to. Real apart. Apparently, he failed to realize that demonic chakra was toxic and while he only absorbed a bit, it was enough to start destroying him on the inside while Fox's sphere was destroying him on the outside.
Eventually, the jutsu ended and Koto's body had turned to ashes from being destroyed. Fox glared down at him with his murdeorus crimson eyes. Before Yamato could release the jutsu, Fox passed out. The others rushed over towards him as he laid down on the ground unconscious.
The many citizens of Snow country quickly came out to see what had happened and were surprised to see that Koto had been killed. The villagers began cheering with excitement that their suffering had finished but soon, they were ordered to get their best medical staff.
Fox was placed in a hospital bed where the chakra fusion was occurring Ali with the medical ninjutsu that was being used to heal both his internal and external wounds from Kyuubi's chakra.
Yugao, Shisui, Yamato, Kakashi, and Itachi were sitting in a room outside of Fox's surgery plaza as they waited for the news from the doctor. Nobody could believe the amount of power and chakra Fox had produced along with using a jutsu that was similar to the fourth Hokage's Rasengan.
"Yugao, Shisui, where did he learn that jutsu?" Kakashi asked as he was reading his make out paradise book.
Glaring at the silver haired man who was reading his perverted book, Yugao sighed. "I'm not sure Kakashi. I've never seen him perform the way he did." Yugao commented.
"Fox produced three tails worth of Kyuubi's chakra. To think the boy was able to maintain control like that. I can only imagine how strong he will be when all nine tails are at his command. Yamato said while flinching at the thought.
"The Galki is going to go far." Shisui said while spinning a kunai around his finger.
Entering the room, the doctor informed everyone that Fox has been stabilized but ordered him not to use any chakra along with only 1 person in at a time. When the doctor exited the room, Yugao entered first and couldn't believe that he was rotating a ball of chakra in his hand.
"What are you going?" Yugao asked.
"Kyuubi informed me that the Rasengan was based off the failed beast bomb. So because I was able to create the real thing, Kyuubi explained the process in more detail and since I can only perform it while using his chakra, I was messing around with the Rasengan." Fox explained.
"Didn't the doctor tell you not to use any chakra?" Yugao asked in a stern tone.
"When has my body not recovered from over exerting myself. I'll be fine though I would like to learn Kakaahi's Chidori. It would perfect for me to use." Fox declared.
After the two spoke for awhile, Yamato, Itachi, and Shisui came to congratulate and praise him for his fear. Kakashi was the last who greeted the boy with a single eye smile.
"How are you feeling?" Kakashi asked the red head in front of him.
"Great. I could go another round."Dix declared with a confident smirk.
"So, who taught you the Rasengan?" Kakashi asked as he got straight to the point.
"Oh the tailed beast sphere? It was Kyuubi who gave me a basic understanding of it. Though I would like to learn you Chidori." Fox said.
"You communicate with it?" Kakashi asked as he began to tense up.
"Yeah, but no worries. He is kind of like my guide. His knowledge and power has been the reason we're alive." Fox explained.
"If I know my knowledge of animals, Foxes are usually ones to be known for having a catch and being sneaky." Kakashi lazily told Fox.
"In exchange, I agreed to help him kill the man who is going by the name of Madara Uchiha. He was the one who summoned Kyuubi to attack years ago." Fox explained.
Kakashi eyes went wide. "I just want you to be careful. Why not work on developing your own personal skills?" Kakashi asked.
"Why? Isn't it the same thing as boosting his?" Fox asked curiously.
"Look at it like this. If you were to ever have Kyuubi's chakra sealed off or were in a position to rely on your own abilities, wouldn't you think that your power would need to be up to par? Consider it the same as a person only relying on their Kekkei Genkai until they are unable to use it." Kakashi thoroughly explained.
"I see... Yes, that does make sense. Okay, yes. I will start training my body to not rely on Kyuubi so much." Fox declared.
"Good." Kakashi said with his wide eye smile. " la, about Chidori. Your Rasengan is far better than assassination jutsu. However, if you do wish to learn it, I will teach it to you on one condition." Kakashi said.
Fox looked at Kakashi with a curious glare. "What is your condition?" Fox asked.
"You take the chunin exams next year." Kakashi said before vanishing in a leaf shun shin.
Fox chuckled. "Here I was thinking that he would ask permission to date my mom." Fox said before he growled at the idea of any pervert dating his mother.
Fox, Weasel, Cat, Fang, Bird, and Dragon. Oared the ship that Hiruzen sent which consisted of Ibiki Moroni, Inoichi Yamanama, and Anko Mitarashi. Since the ship would only take them three days to return, Hiruzen decided it would be fine to send them. To everyone's surprise, Fox ran up and hugged Anko tightly. This made everyone, including the Sadist, Ibiki smile at the young boy before them.
"How did the mission go?" Inoichi asked as he looked at Shisui.
"Great, the Lamd of Snow has been freed and Koto has been killed. We never could find Princess Yukie though I'm sure she will be happy Rick ow her uncle is dead." Shisui said.
"I see. I'm really interested in reading those mission reports." Ibiki said with a smirk.
"It will be one hell of a report. Even I'm still shaken up by what I saw." Kakashi admitted.
Everyone's eyes glanced at Fox who was telling his mother about how much he wanted some dango and ramen and that her training sessions weren't nowhere as bad as he originally thought since they saved his life. Anko smiled brightly at her son and though everyone was concerned about the red head, they couldn't help but smile at a young boy being reunited with his mother.
The three days passed and the two Anbu squads had reported to the Hokage about everything that happened. He was intrigued with Fox's ability to produce not only three tails of demon chakra but to have performed the fourth homage's second most famous jutsu.
"Well it seems this mission has been completed and Fox, as of today, you are an official member of the Anbu Black Ops." Hiruzen said with a smile.
"What do you mean by officially?" Fox asked.
"All new Anbu who were recruited under special circumstances are given a mission exam. By you having this mission successfully completed, you're officially apart of my elite unit." Hiruzen said with a smile.
"Thank you Lord Hokage. I promise, I will protect you and this village with my life." Fox said.
"I look forward to seeing your growth. Now, we have another topic to discuss. Technically, you are still a genin and the first genin to have ever been placed into the Anbu Black Ops. Next year, you will take the chunin exams." Hiruzen declared.
"Yes lord Hokage. Captain Kakashi informed me of that." Fox said in his professional tone.
"I'm aware. The main point and we will go over this when it comes time, but the point of the chunin exams are to promote a villages strength. I believe the rotation while be taking place in Kumo. So it's important that from now until then, you step your training up." The Hokage said as he looked at Naruto with complete seriousness.
Fox gave a bow. "I will not disappoint you Lord Hokage." Fox said and when he was dismissed, he vanished using his body flicker.
Fox had returned home where he noticed his mother had gone off to work. Deciding that he would use this free time to begin his trainigg N, Fox began writing an exercise routine that would push his body passed his limits.
"I see you are taking the cyclops' idea about strengthening your own abilities." Kyuubi muttered.
"That's right. We are a team, the two of us. It's only fair that I pull my own weight, especially if we are going to defeat Madara Uchiha." Fox said.
Fox finished his routine and it revealed to have him run thirty miles a day at top speed, spare with Itachi, Shisui, Anko, or Kakashi. Work on chakra control for a few hours. Perform one thousand push ups, sit ups, squats, and pull ups. Kenjutsu practice with Yugao. Work on wind release and lightning release jutsu. Perform another thirty mile sprint and then finally, practice on conditioning his body with Kyuubi's chakra.
"I can't tell if you are trying to get strivv N we or kill yourself." Kyuubi said with a chuckle.
"I've got an advantage by having my body basically heal itself. This will insure that I'm more than capable to completing this work out. After about six months, I'm going to see if the old man can put together a tougher program." Fox said.
" Be careful what you wish for Gaki. You might just get it." Kyuubi said as Fox exited the apartment and proceeded to go off and train.
