AN: Here, in this chapter, a battle will happen that many were surely expecting, whether in these circumstances or not. Anyway, I hope you enjoy it.

Mako, Bolin, Asami were worried. They had known Naruto for only a few days and now he was going to face their dear friend/girlfriend, who had been brainwashed into thinking they were enemies. They were very worried for both of them, but they knew there was no other alternative to stop their friend/girlfriend.

Meanwhile, Kuvira stood to the side, intently watching the combat that would happen. Unlike the others, she knew nothing of the ninja or his abilities and was going to use that fight to be able to witness it. Deep down, she hoped that neither of them would die.

"You? You must be crazy if you think that." said Korra.

"News flash, they usually tell me that!" said Naruto before gesturing with his hands. "Shadow Clone Jutsu!" shouted Naruto getting engulfed in several smoke explosions around him.

Out of the smoke, several Naruto clones came running out. Korra was taken aback for a moment before she acted and set about quickly throwing multiple rocks.

Some managed to hit most of the clones, but those that dodged the attack continued on their way until they reached the Avatar. One clone tried to punch her in the face, but Korra dodged to the side to dodge it, which left her open for another clone to kick her in the chest, knocking her back before taking another punch from a clone.

Tired of that, Korra spun and sent out a wave of fire that hit the clones around her, making them explode, but then, the real Naruto came out of the smoke caused by the disappearance of his clones and tried to throw a punch, but Korra blocked the attack with her own arms before releasing a blast of wind that sent the ninja flying.

While in mid-air, Naruto threw a kunai at the Avatar, but she used metalbending to spin it around her before throwing it back at the ninja, who, even while in mid-air, leaned to the side to dodge the kunai, though it ended up causing a cut on her cheek.

Shortly after landing, he wiped away the blood coming from the wound.

"Crap. I forgot I could bend the metal too." thought Naruto.

"That's why I told you not to underestimate her." said Kurama.

"True, but she underestimates me too." thought Naruto throwing another kunai.

Korra proceeded to do the same trick as before, but then, she discovered that there was some sort of note attached to the kunai and before she could react, the note caused a loud explosion that pushed Korra to the side.

It was then that a Naruto clone ran towards her and punched her in the face, sending her flying backwards. Right in the area where she was going to land, three Naruto clones positioned themselves there and kicked the Avatar which sent her upwards while Naruto used the first clone as a platform to jump high.

When Korra opened her eyes, she ran into Naruto, who had managed to reach higher than her and before she could react, Naruto came down towards her with his leg extended.

"Naruto Uzumaki Barrage!" shouted Naruto giving her an axe kick in the face, sending her crashing to the ground.

Meanwhile, the four viewers were watching the fight in amazement, but the most surprised was Kuvira. She had seen many things and even had a small visit to the spirit world, but she had never seen such skills.

"Who is that person?" asked Kuvira.

"It's a long story." said Mako not wanting to tell her the story of Naruto's world at the moment.

"Unbelievable. He's hitting Korra hard." said Bolin in amazement.

"I admit it, none of us would have been able to hit her at that level." said Asami.

Naruto landed on the ground without taking his eyes off the Avatar who was getting up after such a blow.

"It seems I have underestimated you. I have no need to hold back anymore." said Korra in a monotone voice.

"Gee, I was wondering when you'd go for real." said Naruto.

"You'll regret not finishing me off." said Korra.

"I'm sorry, but I made a promise and I never break my promises." said Naruto.

Korra proceeded to draw all the water out of her canteen and formed a water platform over the area where Naruto was standing. She then turned the water platform into multiple icicles of ice pointing downward.

Before Naruto could react, Korra sent all the icicles falling. Naruto scrambled quickly from side to side, but unfortunately, some icicles got stuck on his shoulders and some even scraped him. By the time the rain of icicles was over, Naruto brushed off the ones that got stuck on him and then ran off towards Korra.

During the race, Naruto made a gesture with his hands and made several clones appear around him.

Korra was prepared for this and started throwing fireballs, managing to destroy some of the clones. When one clone managed to get close, Korra threw a blast of wind at him that sent him crashing into another clone before she launched a wave of cutting wind that took them both out.

Another clone approached her to hit her, but Korra reacted quickly and erected a pillar from the ground that hit him in the stomach hard, making him disappear.

Then, Naruto stepped through the smoke from the clone to try to kick Korra, but she dodged the kick and gave the ninja a fire-wrapped punch to the face. For a second, she thought she had hit the original, but in the next instant, he disappeared, revealing himself to be a clone.

Korra looked around through the smoke created by the eliminated clones, searching for the original. It was then, when she heard a strange sound and used airbending to push all the smoke away, revealing Naruto approaching her with his hand outstretched towards a clone that was ripping the air over the open hand, forming, in the process, a sphere of blue energy before the clone disappeared.

"Rasengan!" shouted Naruto slamming the sphere into the Avatar's chest, sending her backwards as she went spinning like a top until she impacted against a rock wall, leaving a crater in the process.

"Uuhh. That must have hurt." said Bolin wincing at the blow the Avatar had taken.

"That was a powerful technique." said Kuvira in amazement.

"I hope it didn't hurt her too much." said Mako.

"It won't. He promised." said Asami trusting Naruto's word.

Naruto cautiously approached Korra, who had fallen unconscious to the ground.

"Korra, are you okay?" asked Naruto leaning slightly towards her.

Suddenly, Korra opened her eyes, revealing that she was faking and quickly used earthbending to erect from the ground a pillar that struck Naruto in the chin, sending him flying.

Taking advantage of that, Korra positioned herself on top of him and slapped his chest, thus shooting, a blast of wind that sent the ninja crashing to the ground.

Naruto was groaning from the pain as he was still lying on the ground.

"That's what you get for letting your guard down." said Kurama.

"What do you want me to do? I can't kill her. If there was a way to get her out of that brainwashing, it would all be over." thought Naruto as he started to get up.

"Maybe there is." said Kurama with an idea in mind.

"Really? Which one?" asked Naruto.

"Raava, the spirit that dwells inside Korra should be able to release her from her state." said Kurama.

"Then why hasn't she done it yet?" asked Naruto.

"Maybe it's because she doesn't have enough energy. So, if I give her some of my energy..." began Kurama.

"She might have enough to free Korra. Good idea, Kurama!" thought Naruto.

"Don't claim victory. In order to do that, you have to be in contact with her for quite a while." said Kurama.

"I see. Then there's no choice but to move on to the next level." thought Naruto.

Gesturing with his hands, Naruto created several clones and he and they all launched themselves towards the Avatar.

Korra set about launching attacks from all the elements, thus eliminating most of the clones and when they approached her to hit her, she would dodge the attack before countering with her own blows, managing to eliminate the rest of the clones.

"That trick isn't going to work on me anymore." said Korra.

"I know, but let's see what you say about this trick." said Naruto gesturing with his hands, wrapping himself in a burst of smoke.

Korra braced herself for whatever was going to come out of the smoke, but then...

"Sexy Jutsu!" shouted Naruto coming out of the smoke turned into a woman and completely naked.

Korra was so shocked and, for some reason she didn't know, flushed, that she couldn't react before Naruto punched her hard in the face, sending her backwards.

Meanwhile, the others had various reactions to what the ninja had just done.

Bolin covered his eyes while his face was reddened.

Mako was speechless, as he had known that technique before, but he hadn't expected him to use it in that way.

Kuvira was wide-eyed and petrified, as she had never seen a technique like that before.

Asami was in shock and, without her realizing it, a line of blood ran down her nose.

"We all agreed not to talk about this, right?" asked Mako.

"Yes." said the others in unison as Asami wiped the blood from her nose.

"Wait, why is one of the clones standing there as if meditating?" asked Bolin pointing to a clone who, instead of throwing himself into battle like the others, was sitting in the lotus position and meditating, which was confusing to them.

Korra stood up as she wiped a line of blood coming from her mouth.

"That was a dirty move." said Korra.

"I know, but I would also consider it a distraction." said Naruto who had returned to his old self after hitting the Avatar.

"Distraction for what?" asked Korra.

"For this." said Naruto closing his eyes just as the clone he was meditating on disappeared.

At that moment, when Naruto opened his eyes, they were different, as he had a yellow iris with a toad pupil, as well as orange pigmentation around his eyes.

Naruto had gone into Sage Mode.

"Now I'm going to get serious!" declared Naruto before charging towards her. He threw a punch forward, but Korra dodged it. However, the force of the punch caught up with her and threw her until she slammed into the rocky wall.

Korra was shocked, wondering how that was possible, but then, she saw Naruto running towards her and quickly set about throwing huge fireballs, but Naruto easily dodged them.

Then then, she threw a huge rock, but then, Naruto grabbed the rock with his hands and threw it to the other side, to the surprise of the Avatar who threw several waves of cutting wind, but Naruto also dodged them.

Suddenly, a whip of water wrapped around his leg and lifted him up before sending him crashing to the ground hard.

She thought that with that, she had knocked him down long enough to deliver the final blow, so she quickly jumped towards where he was, but then, she heard a noise and looked over to see Naruto jumping towards her with a clone at his side, but what caught her attention was the huge energy sphere that the two were holding in their hands.

"Odama Rasengan!" the two Naruto shouted before impacting the huge sphere into the Avatar, sending her towards the ground before a loud explosion happened.

The viewers were in shock at what they had seen. They knew Naruto was strong, but seeing him like that showed that he was much stronger than they thought.

"What did he do?" asked Kuvira.

"I don't know, but I'm sure that thing he did with his eyes has something to do with it." said Mako.

"Did you see that? He hit her even though she dodged the attack. How is that possible?" asked Bolin with excitement and surprise.

While Asami was also wondering where Naruto had gotten those skills from, she was worried about a certain person who was the target of those attacks.

"Korra, please come back with us. Come back with me." thought Asami praying that her girlfriend is okay and free from the mind control.

When the smoke cleared, Korra could be seen lying on the ground with Naruto standing in front of her.

Korra let out a groan as she tried to get up, willing herself not to give up, but then, Naruto grabbed her face and pushed her head into the ground with one impact.

"I'm sorry, Korra, but this is necessary." said Naruto. "Kurama, is that enough?"

"Yes, keep her like this for a while." said Kurama.

It was then that Naruto was enveloped in some sort of dark orange energy that then passed towards Korra, covering her with that same energy.

"Raava, if you hear me, I'm giving you Kurama's energy so you can release Korra from her state. I hope that's enough." thought Naruto.

A few seconds passed and nothing happened, much to Naruto's concern until...

"Thank you… Naruto."

Suddenly, Korra's eyes opened, appearing to be bright white while the rest of her body was covered in a blue light.

Before Naruto could react, there was an explosion of light that forced the viewers to cover their eyes.

When the light dissipated, Naruto, who had snapped out of his Sage Mode, turned his gaze to Korra who was lying unconscious on the ground.

"Has… Has it worked?" thought Naruto.

"I'm not sure. All we can do is wait for her to wake up." said Kurama.

"I guess you're right." thought Naruto before grabbing the Avatar in bridal style and heading back to the airship.

When he was at the foot of the entrance ramp, the others rushed down to meet him.

"Korra!" exclaimed Asami as she saw her unconscious bride.

"She's fine. She just needs to rest." said Naruto.

"What was that light earlier?" asked Kuvira.

"Oh, let's just say it was a method to get her out of the brainwashing." said Naruto.

"And did it work?" asked Mako.

"At the moment, I don't know. We'll have to wait to find out." said Naruto.

"Well, at least it all ended well, didn't it?" asked Bolin being optimistic.

Naruto turned his gaze to the engineer.

"What do you think? I kept my word, didn't I?" asked Naruto with a toothy grin.

"Yes, you did. Thank you, Naruto." said Asami with a smile.

AN: Okay, we all knew the clear winner was Naruto, right? It's just that I wanted to drag this out and lower the fighting power a bit, since it was about saving Korra, not killing her.

Anyway, I hope you liked this fight. There will be more in the future with certain guests. Who? Wait and see.
