Hey, had the idea for this fic rattling in my head for a while, so I decided to just get it out.

Naruto will be from the Frozen universe, and will have a power of his own, but not fire. I have no problem with it, but I wanted to do something different and there are a lot of Fire power Naruto/Frozen fics.

I couldn't find out how old Elsa is supposed to be, so in this fic she is 10 when the whole Anna incident happens and 21 in the movie, and Anna is 7 at the tart and 18 later. Naruto will start at 8 then be 19 and Kristoff is the same age as Elsa.

Enjoy:)

Desperate, the King returns to the Trolls looking for help, only to return with a very special young boy with an amazing power.

Chapter 1- The Emotion Eater

XXX

Dismounting his horse as carefully as he could, King Agdar of Arendelle looked around the 'Valley of Living Rock' with a worried expression on his face. It had only been about two months since his last visit, and he only wished his reason for returning so soon was for a less urgent reason, but he needed the Trolls help.

Elsa's powers were getting more and more out of control by the day, and nothing they tried seemed to work, not even the gloves he and his wife had given to her. It got to the point now that his daughter couldn't even leave her room for fear of losing control and someone seeing her use her powers, and it was breaking his heart to see her so alone and scared.

He slowly walking to the centre of the clearing, being careful not to stand on any of the round stones littering the ground, before stopping and looking around.

"Please, I am in need of your help once again, I need to talk with Grand Pabbie right away."

For a moment nothing happened, and although he knew the stones around him weren't actually stones, he was starting to get worried that they wouldn't answer him. Then, without warning they all started to shack and twitch, before unrolling to reveal the small, round creatures that they really were.

He heard them all muttering to themselves, the word King reaching his ears several times, before a small path was cleared so a slightly larger boulder could come rolling towards him, before revealing itself to be Grand Pabbie, the oldest and wisest of the Trolls. He gave a small bow, leaning heavily on his walking stick as he did, before standing back up and addressing the King.

"My King, what brings you back to us so soon, I hope all is well with little Anna?"

Still nervous about leaving his wife and daughters in the castle for too long, Agdar kept looking around as if expecting something to attack him, rubbing his hand together and twitching slightly.

"Anna is fine, Grand Pabbie, but that's not why I am here. Its Elsa, her powers are getting more and more out of control by the day, nothing helps anymore."

Frowning at the Kings words, the elder Troll let out a small sigh, shaking his head slightly before turning to one of his family stood next to him.

"I was afraid it may come to this, please, bring the boy…"

Agdar watched as, without argument the Troll quickly rolled off, disappearing between the trees on the other side of the valley. His attention was brought back to Pabbie when he started speaking again.

"Elsa's powers are closely linked to her emotions, meaning that the more fearful she is, the harder it will be for her to control them. But there is something that might help her, though it could be risky, and it will be little more than a crutch until she is able to learn to truly control her powers."

Giving him a moment to take in what he had said, the old Troll quickly continued.

"About a year ago a young boy wandered into our valley, half-starved and barely conscious, we took him in and nursed him back to health. From what we were able to gather from him, he had stowed away on a merchant ship from a different land, before making his way into the woods. It was while he was recovering that we discovered he, not unlike your daughter, possesses a power…"

Eyes widening at his words, the King was about to ask something, but before he could Pabbie started talking again.

"Unlike Elsa, whose power is over the element of ice, the boy has the ability to both feel and control others emotions, and in some ways…eat them."

"…He eats emotions?"

Seeing the worried look on the Kings face, Pabbie quickly continued before he got the wrong idea.

"Do not rush to judgment, your Majesty, it is not as simple as you may believe. The boy is able to feel a person's emotions, and if he so wishes, change them, but it only lasts for as long as he concentrates and if the person's emotion are too strong he cannot affect them without skin contact. But his most powerful, and dangerous ability, is that he draws power by absorbing the emotions of those around him."

"H-how will you telling me this help my daughter?"

Moving forwards slightly, the elder Troll locked eyes with the King, worried green staring into serious black.

"As I told you before, Elsa's powers are connected to her emotions, emotions that he is able to control…but you must be careful. If he were to absorb too much negative emotion, over balancing the positive if you will, it would lead to disastrous consequences..."

Reaching into an unseen pocket, Pabbie pulled out a handful of the same powered he had used the last time Agdar had been there, before throwing it into the air in front of him. The powered turned into blue smoke, forming into the shape of a small boy playing with kids, before it turned red. Agdar watched in morbid fascination as the other kids that were playing around the first turned red and stopped running around, seeming to get smaller while the fist got bigger. The images ended when the boy was suddenly replaced by a blurry image of some kind of monster, letting out a roar, before the smoke vanished as suddenly as he appeared.

Before he could comment, the Troll Pabbie had sent away before rolled back into the clearing, a small boy following behind him. The moment he saw the small boy, Agdar felt all his worries disappear, as if a great weight had been lifted off of his shoulders, and a small smile spread across his lips. He knew it was the boy controlling his emotions, but for some reason he just couldn't bring himself to care.

Kneeling down in front of him, the smile still on his face, Agdar rested a hand on the boys shoulder.

"Hello, Grand Pabbie says you might be able to help my daughter…"

Elsa was sat on her bed, knees pulled up to her chest as she cried, ice slowly creeping alone the floor and up the walls. The curtains were open, allowing moonlight to flood into the otherwise dark room, making the ice caught in it glow and sparkle. Her father had left to ask the Trolls for help hours ago, and with every passing moment the fear that they wouldn't be able to help crawled deeper and deeper into her heart, which only made the ice form faster.

Standing next to the door, with worried expression on her face was her mother, Queen Idun, watching helplessly as her oldest daughter cried. She wanted so much to run over and hug her, but with Elsa's powers going out of control it was just too dangerous to get any closer, and it was breaking her heart.

"Elsa, please you need to calm down, please stop crying."

"B-but what if they can't help!"

"We'll think of something, please calm-"

"But father's been gone for hours, he should have been back by now!"

At the word now, a small burst of energy exploded out from Elsa's body, leaving ice wherever it touched as the room got colder and colder. Idun took a step back, her back pressing against the wall, her eyes closed as she sent a silent prayer that her husband would return soon.

Apparently someone had been listening, because not a moment later the door opened and he came into the room. The moment she saw her father Elsa let out a small sob, her watery eyes looking to him with such hope it almost hurt, before quickly hugging her legs closer to her body when the ice spread quicker.

"Father!"

Pausing when he saw the state of the room, Agdar gestured to something outside the door, stepping to one side as a small cloaked figure entered, before closing the door behind him. Both Elsa and Idun stared at the person the King had brought into her room, who despite being small, was still too tall to be a Troll. He was covered from head to toe in a dark grey cloak that was much too big for him, one that the Queen recognised as the one her Husband had been wearing when he left earlier, which only confused her more.

"Agdar, why would you bring a stranger to our daughters room, her powers were supposed to be a secr-"

"It's ok Idun…please Naruto, help her…"

For a moment the cloaked figure, now named Naruto, just stood there without moving. Then, slowly, he brought his hands up and pulled the cloak off, revealing himself to the three royals as the cloak fell to the floor.

He looked to be only about a year younger then Elsa, with sun kissed blonde hair and dark blue eyes, wearing nothing but a plain white shirt and brown pants. But what caught their attention the most were the six scars on his face, three on each cheek giving him the appearance of having whiskers, and the fact the boy showed absolutely no emotion on his face. He also had a pair of black leather gloves on his hands, not unlike the ones they had tried to use to control Elsa's powers.

Without making a sound, the young blonde took a step forward, not even pausing when the floor in front of him froze as Elsa moved to the other side of her bed in an attempt to get away.

"Stay away, I don't want to hurt you!"

He didn't listen, just walked towards the young princess, slowly removing his right glove, as she got off the bed and started backing away, Naruto following her step for step until her back hit the wall.

"I said stay AWAY!"

Both the King and Queen flinched as Elsa released another, larger burst of power, both being knocked back slightly from the force. It took a few second for them to regain their senses, and when they did both felt their eyes widen in shock at what they were seeing. The room was now covered in ice, the moonlight making it glow a pale blue, with the exception of a clear line on either side of Naruto. The blonde had managed to close the distance between himself and Elsa in the confusion after the burst of energy, his now un-gloved hand closed around her wrist, and his eyes fixed on hers.

For a moment nothing happened, no one knowing what to say, then Elsa's fear filled face eased into a calm expression and the ice around them stared to melt, much to the shock of the Queen.

"It worked."

Turning to look at her husband, Idun made sure she had his full attention before speaking, her voice barely above a whisper.

"Agar…what is going on?"

The moment his hand touched her skin, Elsa was overcome with a feeling of calm and relaxation, her whole body loosening and her power slowly began to be drawn back into her. Somewhere in the back of her mind, she knew something wasn't right, that this mysterious boy was doing something to her, but at the moment she didn't care. Whatever he was doing, it was helping her control her powers, and that was all she needed to know.

She didn't break eye contact, didn't see the ice melting around them or hear her parents talking across the room, all she saw were his dark blue eyes. Eyes that held nothing, no happiness, no sadness, just stone cold emotionless eyes. It was while she was staring into his eyes that a thought crossed her mind, too quick for her to even realise she had had it before it was gone.

"I could look at his eyes forever…"

Then he was gone, stepping away from her, his hand leaving her skin cold where they had been touching, and the room without a spec of ice to be seen. The moment his hand was no longer touching her, the calm feeling faded, giving way to nervousness. Her mind became a while of questions. Who was this boy, what had be done to make her feel calm, had her father brought him to help her control her powers, and most importantly, did he have powers too?

Then it suddenly hit her that she had been standing with a boy with less than a foot between them, and her face turned a bright red, much to the amusement of her Parents, who were now watching the two children from across the room.

Looking down so she wasn't looking at his face, her previous fear about losing control of her powers momentarily forgotten, Elsa brushed a lock of hair out of her face as she addressed the boy in front of her in barely a whisper.

"Hello…I-I'm Elsa…"

"…Naruto"

She let out a small 'eep' when she heard his voice, which was a lot softer than any boy she had ever heard before, almost like his voice was made of silk.

"What did you do to me...how…?"

After a few seconds passed and Elsa didn't get an answer, she finally looked up to see Naruto with his head tilted slightly to the side, making her blush even more at just how cute he looked, as he stared at her with the same blank expression.

"I eat it…"

"Eat what?"

"Your fear…I could feel it in both you and the ice…so I eat it."

"Y-you're like me, aren't you? You have powers too?"

Again, it took a few second before she got an answer, as if he was thinking over every possible outcome before speaking. But it still came, a small nod of the head, and that was all it took.

Throwing herself forward, closing the distance between her and her fellow blonde, Elsa pulled him into a bone crushing hug as she cried into his chest, more happy then she had been in a long time at finally meeting someone like her.

She wasn't alone anymore.

Things moved quickly after their first meeting, both the King and Queen wanting to help their daughter as quickly as possible. They had the only two remaining servant, Kai and Gerda, move a second bed into Elsa's room for Naruto to sleep in, wanting to keep the two together as much a possible so that the whiskered boy would be there if she lost control again. They also spread the news that Naruto was to be her personal servant/bodyguard from now on, that way no one would ask why the two were always together, and arranged for him to start taking lessons from the Captain of the Guard.

They arranged for him to have a whole new wardrobe, seeing as the only clothes he had were the one he arrived in, and the Queen started teaching him things like manners and how to read and write. Naruto took to it all like a fish in water, seeming to soak up everything they taught him at an amazing speed, but the thing he most excelled in were his combat lesson with the Captain. The only strange thing was that the boy refused to wear any of the armour they tried to give him, preferring to fight in normal cloths.

When asked why he didn't want to wear any armour, the boy had simple said he didn't find it practical for what he was being trained to do, and that it only slowed him down. At first the Captain had tried to argue, but after the first few lessons passed and he saw the blonde's raw talent, he reluctantly agreed.

Naruto soon fell into a routine for his life in the castle, he would get up, clean himself and get dressed, and then he would go fetch Elsa's breakfast from the kitchen. After she had finished he would make her bed while she got cleaned and dressed, before heading down to the caught yard for his training. When that was done, he would return to his and Elsa's room to get changed, then the Queen would come and start to give him lessons, the young Princess helping however she could.

Whenever they were in the same room, Elsa made an effort to always be within touching distance of Naruto, just encase anything happened, and when they were alone she would often find herself talking to him constantly. He was a good listener, hardly ever speaking unless he needed to, Naruto would just sit and listen to whatever she needed to get off her chest, which apparently was a lot.

He also didn't miss the pained expression that would crossed her face every time a particular voice would reach them from the other side of the usually locked door, a voice that obviously belonged to a little girl, that would constantly ask her to come and play. Naruto hadn't actually met her face to face yet, but Elsa did tell him she was her sister, but knew that he would run into her one day.

The only negative about living in the castle for Naruto was that he missed the Trolls, along with Kristoff and Sven, and often wondered how they were doing.

Surprisingly it took two weeks before Naruto would run into Princess Anna, he had been returning with Elsa's launch when he paused at the sight of a small red headed girl looking practically in tears as she turned away from the locked door. He was dressed in one of the outfits the King and Queen had given him, a black suit with a white shirt, and the same black gloves the Trolls had given him when they found out about his powers.

The moment her large, blue eyes turned to him they seemed to widen even more, and before he knew what was happening she was stood in front of him with a large smile on her face. Naruto was forced to move the silver tray in his hands out of the way just to stop her knocking it out of his hands, the food barley staying on, but his emotionless expression never wavered.

"Hi, I'm Anna!"

"…Naruto"

"Who are? Why are you here? Is that for Elsa? Do you want to play?"

While inwardly his head was spinning at the rapid fire questions being shot at him, on the outside the only reaction Naruto had was to blink and stare at the young Princess in front of him, who seemed to realise she was talking to fast and got a sheepish expression on her face.

"Sorry, I was just so excited to see someone my own age, guess I over reacted…"

Not liking the negative emotion he could feel coming off of her, Naruto shook his head and waited for her to look at him again before speaking.

"…its fine, I don't mind, but I am afraid I don't have time to play with you. Now if you will excuse me, Elsa is waiting for her lunch."

Still feeling her negativity, Naruto focused for a moment and like a switch Anna gave him a large smile as she took a step back so he could get to the door, her attitude changing instantly.

"Oh ok, maybe some other time? We could build a snowman!"

Before he had a chance to answer, the little redhead ran off down the corridor, leaving a still emotionless Naruto standing outside his and Elsa's room.

When he entered the room, Naruto found Elsa leaning against the wall next to the door with a sad look on her face, which instantly changed the moment she saw her fellow blonde.

"Thank you, for making Anna feel better, it means a lot to me that you did that."

Nodding in her direction, Naruto made his way over to the table and set the tray down, slowly placing the food on either side for them both to eat. Normally a servant wouldn't eat with the princess, but Elsa insisted he join her for her meals, and that he was only a servant in name so he had an excuse to be around her. It didn't make much difference to him, but it was a nice gesture all the same.

After they were finished, Naruto collected the plates and was about to leave, but stopped when he felt a shift in Elsa's emotions and turned to look at her. From the expression on her face, and the ice slowly creeping along the floor at her feet, he knew there was something bothering her, so he waited a moment until she spoke.

"Am I doing the right thing, distancing myself from Anna I mean?"

"…it's not my place to say if you are right or wrong."

Frowning slightly, Elsa locked her eyes on her friend, because that was what he was, her friend, not a servant.

"How many times do I have to tell you Naruto, you're not actually my servant, you can say anything to my."

"I am aware of that, Elsa, but you misunderstood. What I meant was that it wasn't my place to say if what you are doing is right or wrong, because whether you distance yourself from your sister or not, both option have different positives and negatives."

Blushing slightly at her mistake, Elsa took a moment to think about what Naruto was saying, before letting out a deep sigh and slumping in her chair.

"I guess you're right, but until I can control my powers without you, I can't put Anna at risk like that. Its better I wait, then make up for lost time when it's safe for me to be around her again…"

By the end of her little rant, Naruto knew she was talking to herself more than him, and the moment the ice on the ground started spreading faster he made her calm down. It was a feeling Elsa was getting used to, Naruto changing, or as he called it, eating her emotions, and one she was glad to be feeling at the moment.

Smiling, the blonde princess looked over to her friend, who was making his way to the door with the dirty dishes placed on the try in his hands.

"You know having you around is better than a warm bath any day."

She said it without thinking, and the moment she realised what she said her face turned bright red and she looked away before he could see it, forgetting for a moment that he could feel her embarrassment with his powers.

The moment Naruto was alone, he let out a slightly pained sigh and leaned against a wall, his breathing slightly laboured and eyes screwed shut in pain. if anyone had been present when he opened his eyes again, they would have been shocked to find his normally dark blue eyes changed into a deep, blood red with a slit pupil. Then suddenly his hands, which were still holding the silver tray, were covered in red energy.

Before he had time to pull it back in, the metal where his hands were holding the tray turned to liquid in his hands, falling to the floor with a slight hiss before being followed by the rest of the tray. Within seconds it was nothing but a melted pile of sludge, even the dirty dishes melting and mixing with the metal.

His breathing picking up slightly, Naruto focus his mind on happy thoughts, trying to counter the negative emotions he had been absorbing with positive ones of his own. It took several minutes, but eventually he was able to rain in the energy, leaving him in a hall with a pile of melted silver sludge and a strong acidic smell crawling up his nose.

Letting out a sigh, Naruto wiped the sweat off his forehead, returned his face to its usual blank expression, and went to find something to clean up the mess he made before someone found it.
