Ok this is a fic I just HAD to write, it was eating at my brain and I had to get it out. I'm a big fan of the ReMonster Light Novels and Rou's ability is just awesome, just like its owner.

Obviously this is OP Naruto (the wielder of that ability can be nothing less), not sure as far as relationship goes, smart Naruto, M Rating

Chapter 1

W-what was going on?! His arm! What was happening to his arm?! Was he seeing things, was the hunger getting to him? It was likely since he'd been hungry enough to eat a giant bug earlier, now he was seeing his arm covered in some black stuff that looked like a bug's shell.

Wait it wasn't just his arm it was his entire body! WHAT WAS GOING ON!

Something that sounded like a chiming bell suddenly went off in his head and something clicked

Ability [Exosceleton] learned.

Seriously just what the heck was happening?

Ok he'd found out he could make the uh, exo bug thingy, vanish and appear at will, he also found out that things didn't hurt as much when it was there, likehe was wearing armor even if it didn't feel like he was wearing anything other than his normal clothes, but when he used it to keep the orphanage lady from hurting him, she'd started screaming something about demonic powers and kicked him out. So here he was in the same place he'd first found the big beetle, he had been scared to come here since last time since he'd barely survived and had killed it by luck, but he was tougher now that he had his armor right? and he was so hungry.

He climbed over the ignoring the sign since no one had taught him how to read anyways and what he'd picked up from watching the orphanage lady teach other kids wasn't enough to understand it.

If he could have understood it though he'd have learned that it read 'Training Ground 44: The Forest of Death'

Ability [Spider Thread Creation] learned

Ability [Thread Wielding Arts] learned

He tilted his head as he heard the same chime as before, instinctively he raised his hand and shot out a line of thread from his finger, without thinking he wove the thread into something like a bag and stored the rest of the giant spider for later.

This time he'd somehow gotten two things instead of one; why was that? Was it something special about what he was eating? Did his strange ability somehow get stronger? Or maybe it was random?

But those thoughts were brushed aside by one resounding thought

If he ate the same thing again would he get whatever he missed?

He turned to the back to face the darkness of the forest and licked his lips

Suddenly he didn't feel quite so full anymore

His face was split into a massive grin even as he walked back into the village that had become his own personal hell, it had worked, he'd managed to kill another beetle (oddly enough as it looked different from the first one and proved to be harder to kill than the it as well, it tore though his threads to), and had gotten some new abilities when he ate it.

[Herculean Strength]and [Insect Wing Generation]

He could feel the strength coursing though his body, hidden just below the surface.

It felt amazing.

And he learned that he loved flying, the feeling of freedom was even more amazing than the strength was.

He'd slept in a cave he'd found after sealing the entrance with a giant web last night and felt like nothing could ruin his day, not even the looks tossed at him by the villagers did anything to remove the smile on his face. Well ok it affected him somewhat but he refused to let them get to him, how was he gonna be a ninja like his awesome jiji if he let a few looks beat him.

He frowned at the thought of his jiji, should he tell him about his new power? He didn't want him to start screaming at him like the old orphanage lady, but this was his jiji, he wouldn't do that.

Would he?

He didn't want to find out.

Right! He'd keep it to himself for now.

He paused and looked down at his bag of spider legs with a pout, he quickly devoured all the legs and tossed away the bag, he knew for a fact that even if people would eat bugs they certainly would't do it raw, so walking into his jijis office with a bag of spiders legs snacks would be bad.

He brushed off the losses, figuring he could always make a new bag and find another spider, and continued on his way to the hokage tower. Mqybe today Jiji would finally let him go to the academy, or at least teach him to use that cha-ka-ra thing that ninjas used.

He'd also him how life at the orphanage was, but he didn't want to trouble the old man, so he lied and said everything was fine, he liked sleeping in the forest anyways.

Naruto pouted to himself, the visit had been a bust, Jiji said teaching him would be showing favoritism or something, and he said he still had to wait another year before he could go to the academy, ah well he had a forest full of stuff to eat and get stronger, on fact he was hunting right now.

He had his wings and armor out right now and was going deeper into the forest than he'd been able to on foot to see if he found something new to snack on. He continued on for a few minutes before he found a river and stopped.

A river.

Rivers had fish right?

He'd never had fish before! The orphanage people would only give him some rice, stale bread and water. He looked around for a bit and then he saw it.

A ginormous fish swimming upstream, it was easily twice as big as even the beetle and spider from before, he licked his lips and wondered how he would get it, along with never teaching him how to read he'd never been taught how to swim either. He folded his arms in thought even as he hovered after the fish, wondering how to catch it.

After a while they came up to a small waterfall in the river, his eyes widened as he saw the fish leap out and over it, before continuing on its way. That was how he'd catch it! He unfolded his arms, waiting for the next time the fish would jump, finally after a while of trailing they came across another fall, he tensed in preparation.

The fish leaped.

NOW!

He swooped down the moment the fish broke the surface and caught it in midair before tossing it onto dry land. His grin was as bug as it had been this morning as he watched his prey flopping helplessly on the ground. A quick kick to the head put it out of its misery and like that lunch was served.

He wasted no time in retracting his exoskeleton and wings and digging in

And it was the best thing he'd ever tasted.

Ability [Swim] learned
Ability [Aquatic] learned

Well that solved his issues with catching fish, sweet.

Picking his teeth with the bones of the fish he cleaned himself in the river and then made his way back into the foliage.

An hour of walking later he'd heard a sound similar to a hiss coming from above him and looked up, over on the a tree was another spider. He frowned at it, like how the two beetles looked different, this spider looked different from the last one, it was a bit smaller, its legs had yellow stripes and its teeth were bigger.

Well whatever, different or not it obviously wanted to make a meal out of him, it would learn the error of its ways soon enough, at least for the short while before it was killed and turned into a meal itself. He focused some of his Herculean strength(not much) to his legs and leapt back as it tried to drop down on him. He landed in a crouch and immediately had to leap out of the way again to dodge the thing's lunge, even so it's fangs managed to scratch his arm. This thing was fast.

He glared at the spider before a feral grin stretched across his face.

He leaped at the spider with enough force to leave a small crater on the ground he'd stood on and tackled his prey before it could react, his exoskeleton forming a black armor on his hands and forearms. The spider managed to sink a fang into his shoulder but he'd simply gritted his teeth and ignored the pain, even at his young age pain was nothing new to him, it couldn't be with how the villagers and orphanage lady treated him.

He reared his arm back, ripping the fang from his shoulder as he did so and punched forward with his full might, his fist ignored the spider's shell as if it wasn't even there and sank into it, the only reason his fist hadn't burst out the other end was because his arm was too short, but it was more than enough, the thing thrashed on his arm, releasing released screeches and hisses of pain and rage before finally becoming still.

Satisfied the spider was dead he ripped his arm free of its carcass and jumped away before he got splashed with its guts and blood, he didn't want to explain to the old man where the stains came from. He relaxed when the corpse fell to the ground in an unmoving heap and felt a sharp pain in his shoulder, he looked to see what it was and blinked in surprise before looking back at the spider, specifically its fangs.

Yep, the one that had bitten into him had been broken off. He reached up and yanked it out of his shoulder with a grunt, idly wondering what that black liquid that leaked from it and was in his shoulder was, but brushing it off as he saw his wound start steaming and closing like all the other wounds he'd ever gotten, in a little while all that would be left was a hole in his shirt with a tiny bit of blood stained on it, something easily passed off as a playground injury he figured, he'd seen that excuse being given to Jiji enough times to know it worked.

He turned his gaze back to the fang in his hand and shrugged before taking a bite out of it.

Mmm crunchy, and with some new flavor he hadn't tasted before.

Ability [Venomous Bite] learned

He tilted his head at the familiar chime and the feel of something suddenly clicking into place in his mind as he suddenly knew what the black liquid and taste was.

Venom? That was another word for poison right?

In that case..

He glanced back at his rapidly healing shoulder, then glanced at the place on his arm where the spider had scratched earlier, already healed completely.

'Why didn't it do anything?' He thought as his face scrunched up in thought, did poison not work on him? Was it another part of his strange ability?

Awesome!

He grinned before finishing of the piece of spider fang and moving on to the rest of the spider

Ability [Enlarged Field of Vision] learned

Woah, the world suddenly seemed to expand around him, no not expand, it was the same size, he was just seeing more.

Alot more.

So this is how spiders saw stuff?

It was weird but at the same time oddly cool.

He decided to leave it on so he'd get used to it.

But now he wanted to test his new bite.

His wings popped out and started to hover, then turned back the way he'd just came from. Maybe he'd find something that wasn't a bug to eat, he hadn't found any so far so they were probably deeper in right?

He wondered what actual meat tasted like.

Naruto crashed hard onto the ground just outside the fence, his shirt shredded off his body which was covered in bloody slashes, even through his exoskeleton.

'Tigers are scary!'

He'd found an animal, oh he'd found an animal, but the thing very nearly killed him, despite being stronger than it it was worthless since the thing seemed to be able to dodge everything, even his powerful lunges, its claws tore through his exoskeleton like it was wet tissue paper and he'd never seen anything fight that viciously before in his life, in the end he'd never been more grateful for his wings than he currently was as he'd flown away the minute he'd had the chance.

Assuming he'd be able to kill everything in the forest had been stupid, it seems the deeper in he went the stronger the beasts were so he'd have to gather strength on the outer edges like he'd been doing, but if something really strong decided to come out he'd be dead wouldn't he?

He needed to be more prepared.

First things first, he needed a weapon.

Well there it is I've created the first ever (to my knowledge) Naruto and ReMonster Crossover, and given Naruto one of the most OP powers I've ever seen in my life to abuse.

Current Abilities List:

Absorbtion(His Eating Ability)

Thread Wielding Arts
Herculean Strength
Insect Wing Generation
Aquatic (I won't be counting swim so don't ever expect it on the list)
Venomous Bite
Enlarged Field of Vision

The creatures in the Forest of Death are pretty much chakra mutations, but there's no reason there wouldn't be others around the world, I plan on bringing in some ReMonster beasts as chakra mutations, nothing like Slimes, Kobolds or Orcs ofcourse but expect somethings like Seven Colored Bat to show up, though in numerous cases it will take a while for Naruto to meet them as they will NOT be in the forest of death, a few low leveled ones might be in there but if you think he'll be finding Hind Bears or God forbid Red Bears in there then forget it.

I might take beasts from other shows as well if I like them, leave me some ideas in the reviews and I'll see if I use it.
