Leviathan of the Maelstrom

Disclaimer: I do NOT own Naruto.

Summary: Demonic chakra can sometimes have some unpredictable side effects on Jutsu. So, when Naruto used it to summon a Toad, he got something else instead. To be specific, a seemingly infinitely long sea monster that thinks Toads are useless and that Jiraiya is a child molester. Bijuu, Summons, make way for a real monster! Pairing Undecided.

Demonic or Animalistic Thoughts

Between meeting the Kyuubi face to face, digging up the courage to yell at it and demand its chakra, and being a little freaked out when he finally got it, Naruto had kind of forgotten the exact direness of his current situation: Falling to certain death if he didn't summon a fucking toad. He began running through the hand signs for the summoning Jutsu as he fell further and further into the ravine, pouring demonic chakra into it, 'Please don't be a tadpole, please don't be a tadpole, please don't be a fucking tadpole!' He mentally prayed as he finished the Jutsu, "Summoning Jutsu!" He yelled before being engulfed in a cloud of smoke.

The next thing Naruto knew was that he was standing on something hard, followed by the noise of rocks breaking and cracking off the wall as whatever he summoned stopped its descent, "Wow! I think I actually did it that time!" Naruto cheered as the smoke started to clear, blinking as he looked down at the rough, dark-blue scales he was standing on, "Huh? Do toads have scales like this?" He asked curiously as he knelt down to examine them. They weren't smooth or leathery like he was expecting. They were keeled scales, rough with ridges.

Getting a bit nervous, Naruto stood up and looked around, trying to get a better look at this thing. He slowly paled as the smoke cleared, "This...is not...a toad," He said slowly as he realized several things. One was that this creature had no arms or legs that he could see. It was keeping itself up by keeping its long body zigzagged and stiff, the turns of its body pressed against the walls. This also brought Naruto to his second realization. This thing, whatever it was, was long as hell! Its body zigzagged between the canyon walls many times, stretching back for what looked like a mile, at least, before fading out of view.

Naruto slowly looked over the edge and gulped. Not at the height, mind you, but at the fact that he could see the tail going down into the blackness and he still couldn't see the end of the tail. Feeling the giant muscles twitch and move a bit under him, Naruto quickly got back up on his feet and looked towards where he believed was the front of the creature. It only zigzagged against the walls a few times this way before tipping downwards, out of view.

"Umm, hey! Can you hear me...giant snake-thing?" Naruto called, feeling as lame as he sounded for saying that.

All at once, the front of the beast began to move upward, it's craned down head out of view as it adjusted itself in the relatively narrow space. Towering Naruto, it slowly turned its head, making Naruto almost step back in shock. It had horns; it could have been two, or more, because they were covered in sharp coral and rocks, looking almost like a crown with a gap down the middle. Its jaw was long, with two pronounced lines leading towards the nostrils, ending in an almost hook-like fashion. From said nose, thick smoke billowed, flames flaring when it breathed through them. Its mouth was filled with teeth that were several feet long each. But its eyes were perhaps the most intimidating sight. They glowed with an unearthly light, like two suns rising over the morning dawn. Naruto couldn't even make out any eye color behind those lights.

While a snake couldn't blink, this one seemed to gain a surprised and confused look before a vertical, semi-transparent lens slid over and covered the eyes, giving it a milky appearance, but also showing that the creature had golden whites, and slit pupils in its neon green eyes.

Naruto and the serpent stared at each other for the longest time before one of them got either too curious or too annoyed, "Mi ata?" The serpent said, tilting his -or at least it sounded male- enormous head questioningly.

"Huh?" Naruto said in confusion, not understanding what that word was, if it even was a word.

"Poios e sai?" The giant tried, saying it a bit more slowly this time.

"I...I don't understand?" Naruto tried again.

The snake's head perked up for a moment as if trying to think on something before gaining a new look of hopefulness, "Ni sh sh i?" He asked.

"What language are you even speaking!?" Naruto yelled, getting a bit frustrated.

"Well forgive me for not expecting to show up so suddenly in your lands, you little shit-stain! It's not like I can recognize Japanese from every other language off the tip of my tail!" The snake yelled back, shaking the walls and making Naruto fall backwards...clutching his nose.

"Ohhh, gods the smell! Snake, your breath is lethal!" Naruto hollered through his jumpsuit, using it to cover his nose as he rolled on the back of the enormous beast, who gained a tick mark at that.

"I am not some garden snake!" The Not-Snake retorted in outrage before taking a calming breath, "And I'm sorry about the breath, that whale I ate yesterday is leaving a worse odor than normal," He said in annoyance at his oral health issue.

Naruto took a few moments to fill his lungs with fresh air, "S-sorry about that, and yelling at you...what were you saying?" Naruto asked, trying to be somewhat civil with the giant ...serpent, 'Great, not only do I meet a giant fox with anger issues today, but I also meet a giant snake with identity issues. Somehow, I know the Kyuubi did this on purpose,' He thought in worry.

"I was trying to ask who you are, Human," The scaly creature answered evenly.

"Naruto Uzumaki, Next Hokage," Naruto answered cheekily.

"...Naruto Uzu-what? Yahweh, why did I have to get sent to a land that has one of the only language I never got a full grasp on...," The beast groaned, shaking its head in exasperation, "Speaking of which, how in Gehenna did I get here?" He asked curiously.

"I...well, I was trying to use a Summoning Jutsu, but for some reason, you showed up," Naruto said sheepishly.

"Summoning Jut- Okay, now I think you humans are just making these words up as you go," The creature said in annoyance.

"How do you NOT know what a Jutsu is!?" Naruto asked in disbelief.

"How do you summon something like ME by mistake?!" He responded in kind.

"I don't know, ask the perverted sage!" Naruto answered with a 'humph'.

"Perverted...sage. Two words that should have never been used together to describe someone," The creature said blankly with a sigh, "So, what, a Jutsu is a ritual basically?" He asked for clarification.

"Yeah, kind of," Naruto said with a shrug, "By the way, I never got your name?"

"...Seriously? You don't have a name for me?" The summoned beast asked, sounding oddly surprised.

"Eh? Whatcha mean?" Naruto asked curiously.

How a limbless reptile could do a shrugging motion, Naruto didn't know, but this one pulled it off, "Every place I go to, everyone already has some legend and name about me, or something like me," He admitted, "I just got used to everyone assuming they already knew my name."

Naruto shrugged in return, "Eh, I've heard about lots of giant animals before, but I didn't catch all of their names," He said offhandedly.

"Hmm, well, my name is Leviathan. Nice to meet you," The now christened Leviathan answered.

"Nice to meet you too, Leviathan," Naruto greeted with a grin, "Umm, sorry about summoning you though. Something...went wrong I suppose. That or I over did it," Naruto apologized with a chuckle, 'Well, on the upside, at least he doesn't want to eat me.'

"Guess I can't fault a kid that is messing with magic, that's bound to cause a mess," Leviathan muttered to himself, getting a sweat-drop from Naruto, "But what were you trying to summon anyway- and why the Gehenna hasn't my tail found the bottom of this damn canyon!?" The reptile yelled in disbelief, flaring his flaming nostril in frustration as it looked down for a moment.

"Yeah, it's pretty deep. Good thing too, or I might have hit the bottom before I summoned you," Naruto said with a grin, "I was about to ask if you were getting tired holding yourself up like this anyway,." He added on, looking over his shoulder at the zigzagging body.

"I've done a lot more strenuous stuff than this, I'm fine for now. Still a bit in climate shock after going from swimming on a nice deep-sea current, to what feels like summer in the tropics!" Leviathan ranted a bit, panting a bit at the end.

"...You okay?" Naruto asked curiously.

"Yeah, yeah, just give me a second. I haven't been surprised like this in a LONG time...somehow, I just know that Behemoth and Ziz have something to do with this," He muttered to himself, "So...what were you trying to summon?" He asked again, wanting to change the subject.

"A toad," Naruto answered simply.

"...A toad?" Leviathan repeated.

"Yeah, kept getting tadpoles for the longest times," Naruto answered with a nod.

"...Why?" Leviathan asked, scrunching its brow.

"I don't know, something about not putting enough chakra into the Jutsu or something," Naruto explained with a sigh, honestly not really remembering at this point.

"No, I mean why would you WANT to summon a toad in the first place?" Leviathan asked blankly.

"What do you mean?" Naruto asked.

"It's a jumping, slimy nuisance you can find in almost any swamp! Why would you NEED to summon one at all?! What would be the point?" Leviathan asked in confusion.

"Well it was supposed to be a giant toad...," Naruto answered a bit lamely, kind of seeing the Leviathan's point.

"Big whoopty fucking do, you'd get a giant jumping, slimy nuisance. Seriously, the only thing I can think of that would make a giant toad useful is if it was dropped on top of something or if it was poisonous on the skin, and that would just make almost any situation worse…maybe if you had a giant fly problem, it might be useful! A giant toad is more useless that a giant worm! At least the worm could constrict and dig underground. Of all the beasts to walk the earth, you pick one of the few that has to be the most useless. At least pick something that has fangs, or claws, or something redeemable!" The Leviathan ranted, his nostrils crackling in irritation.

"Okay, I get it; I wasn't too fond of the idea either. But the Pervy Sage only has a toad contract, and I need all the help I can get," Naruto answered, trying to placate the enormous beast.

"That's the second time you've mentioned this Pervy Sage...I'm assuming he's a teacher of sorts?" Leviathan asked curiously, 'A bad one by the sounds of it...'

"Yeah, kind of. He's teaching me to summon toads since my other teacher was pretty much useless," Naruto said with a sigh at the thought of Ebisu, "And while toads aren't the coolest thing around, they're better than nothing."

"Still...his teaching methods involve you jumping into the gorge while you were still summoning baby frogs?" The great whale eater asked skeptically as he looked at the long way up.

"Actually, he didn't tell me to do that. He just threw me off it to make me get it right, more or less, after we spent the day trying," Naruto said with a sigh, almost losing his balance as the Leviathan stiffened. The serpent slowly looked at Naruto, than back up, than back at Naruto, and back up once more before settling on Naruto, "...What?"

"It sounds more like he was trying to kill you!" Leviathan roared in shock, "Wha-what the actual shit!? You don't put a kid into a do-or-die situation just because he couldn't get it right in a single day! That's...That's not impatient, that's not bad teaching, that's damn retarded! Not to mention child endangerment! How did your parents ever let you learn from a guy like this?!" He asked in disbelief.

"Actually...I'm an orphan," Naruto pointed out awkwardly, having no other way around that question.

"...Kid, I take back every bad thing I said or thought about you up until now. Because that is just...that's just wrong on so many levels, taking advantage of a kid without a family to watch his back...wait, you keep calling him a pervert- IS THIS ASSHOLE A CHILD MOLESTER!?"Leviathan roared, making towers of flames shoot from his nostrils as his eyes blazed behind the protective lens.

"No, no nothing like that! I just call him that because he writes pervy books and peeps on women!" Naruto assured quickly.

"Are you sure...?" Leviathan asked in concern.

"Ye-...Well...he did want me to use my sexy Jutsu all the time when training with him, but I only had to use it make him focus on training me rather peeping on the girls," Naruto answered uneasily.

"...Sexy Jutsu...?" Leviathan asked in dread.

"It's...It's a Jutsu I use to make me look like a naked sexy girl version of myself," Naruto answered sheepishly.

Leviathan went blank face at that, 'Must. Kill. Perverted. Sage,' He thought darkly as he sighed and regained his composure, "Well, my tail found the bottom. I can get us out of here safely...," He said offhandedly as his body began to relax against the walls, "You may want to grab onto something," He instructed as his body began to straighten out and head upwards.

"How fucking long are you?!" Naruto yelled as he crouched down and gripped onto the scaly hind with chakra as Leviathan headed straight upwards, on his own muscle power.

Leviathan just chuckled to himself as he rose to the surface.

Meanwhile

Jiraiya was officially getting a bit worried. He had seen Naruto preform the Jutsu and the large cloud of smoke that followed. After hearing the summon stop the very rapid descent it and its summoner were in, he had grinned in pride that his plan had paid off. So, he sat down by a tree and waited for Naruto, and whatever toad he made appear, to jump out of the gorge. But after several long minutes, nothing happened. Not even the sound of something large hitting the bottom or the 'poof' of a large summon dispersing.

'What hell is taking them so long? Did they decide to have a nice chat in a ravine?' He wondered to himself as he stood up and approached the large crack in the ground. Now, Jiraiya admitted to himself, he wasn't sure what demon chakra would do to a summoning Jutsu. But in all honesty, the most he was expecting was a fox summon instead of a toad. Or even a demonic toad. A frog would have even been unsurprising.

He did not, however, think he would see the head and body of a creature that seemed more fitting for his traitorous teammate to shoot out of the ravine, right as Jiraiya himself reached it. Jiraiya jumped back with a gasp he watched the beast rise several dozen feet into the air before coming back down and resting its head on the ledge, "Hey, Uzu-whatisit? You climbing up or do I need to do everything for you?" Leviathan called, looking back out of the corner of its eye.

"Yeah, yeah, I'm coming!" Naruto called back in annoyance as he used his chakra to climb up the Leviathan's back. If said sea monster had eyes in the back of his head, he might have commented on Naruto walking up a near vertical ascent the way he was. As it was, he just waited for the human to reach his head, "Is there something etched in your horns?" Naruto asked in surprise, rubbing away some of the loose coral and rock as he reached it.

"Oh, yeah, some asshole carved some things on it. Everyone tells me it's all compliments, like how 'I am one of the greatest creatures that inhabit the sea.' and 'I am three hundred miles in length,''" Leviathan answered gruffly, "I'm sure there's more than one insult in there and no one wants to tell me." He grumbled.

"Sorry, but I don't understand whatever langua-DID YOU JUST SAY YOU'RE THREE HUNDRED MILES LONG?!" Naruto yelled in disbelief as that line registered.

Jiraiya, still unnoticed by the pair, staggered backwards as he eavesdropped on the conversation. He quickly looked over the edge and found that the body of the Leviathan seemed to go on forever and ever, 'Holy shit, did Naruto summon a snake God or something?!' Jiraiya wondered in growing dread.

"YOU'RE RIGHT NEXT TO MY EARHOLE, YOU HOWLER MONKEY!" Leviathan roared in anger, "And as for how long I am, I have no fucking idea! You think I memorized and grasp your human measuring systems at my size?! You could say I was three centimeters and I couldn't refute you in complete certainty!" He elaborated, still very annoyed.

"Jeeze, jeeze, Okay!" Naruto said in verbal surrender as he jumped off the head, "Still, if you're anywhere close to that size, you're way too big to have this close to the village." Naruto said, rubbing his chin thoughtfully.

"Oh please," Leviathan said with a roll of his eyes, his body glowing light as it rapidly shrunk down. In his place, there was a forty foot version of himself, his body about as thick as an adult human thigh, curled up in front of Naruto into a large cone-shaped pile of flesh, "You think I don't know how to change size, Kid? Give me SOME credit," He said, feigning arrogance.

"Sweet! Still, you're going to scare any non-ninja shitless on sight," Naruto warned with a grin.

"I'm the Goddamn Leviathan! I'd be insulted if I didn't scare people!" Leviathan reminded with a small glare.

"Umm, not to interrupt this riveting conversation...?" Jiraiya spoke up tentatively, getting both of their attention.

"Oh, hey Pervy Sage, didn't see you there," Naruto greeted over his shoulder.

"Naruto, how exactly did you su-AH!" Jiraiya screamed as the tail to Leviathan's still seemingly infinite form swung out and tried to grab him. Luckily, being one of the Sannin, Jiraiya was able to dodge it, "What the hell was that for?!" Jiraiya yelled in annoyance as Leviathan leered at him.

"For being a pedophile, you creep," Leviathan answered scathingly, making Jiraiya face-fault.

"Naruto, what have you been telling him?!" Jiraiya asked in alarm and dismay at his student.

"Yeah...Leviathan here doesn't know our language perfectly. I told him about how I had to use the sexy Jutsu to get you to help me...and I think he misunderstood something along the way," Naruto answered with a sheepish chuckle.

"Ohh, I didn't misunderstand anything," Leviathan retorted tonelessly as his lenses retracted, releasing the unholy lights of his eyes upon the world, and flaring his nostrils for good effect.

"What the hell is th-AH!" Jiraiya started, only for Leviathan to take advantage of his surprise and slam his tail down on him, "Okay, you got that out of your sy-AH," The Toad Sage hit the ground again, so hard this time that he bounced back up and got flicked back down Leviathan, repeating the process with loud thuds echoing through the air, waves going through his tail for each hit.

"Umm, Leviathan?" Naruto asked tentatively after several long seconds, hoping to make him stop.

"I'm almost done," He assured evenly, hitting Jiraiya for the thirtieth time, leaving the supposedly great ninja lying in a crater as a heap of bruises and cracked bones, "Okay, I'm good," He said plainly, recovering his eyes again.

"Thanks, I probably might need him for training still," Naruto reminded sheepishly.

"Training in what? How to be a creep? We've already covered that Toads are pointless for summoning, even in giant form. Besides, even if I wasn't sure this guy wasn't a pedo, I'm not about to leave you alone with a guy that throws impressionable kids off cliffs when he gets impatient," Leviathan countered, still very annoyed with those topics.

"But without him, how am I supposed to train?!" Naruto pointed out, "I don't exactly have a lot of options in teachers here!"

"Naruto, "I" will teach you ancient arcane rituals LONG before I leave you alone with him." Leviathan said evenly.

"You know a Jutsu?" Naruto asked in surprise.

"I've been around since before mankind existed, I picked up on a few things," Leviathan said flatly.

"Wow...you're old," Naruto quipped with a chuckle.

"Tell a goldfish that you're over ten years old, and it'll say the same thing," Leviathan countered gruffly.

"So...are you going to disperse soon?" Naruto asked curiously.

"Disperse?" Leviathan asked blankly.

"Umm, yeah. The Pervy Sage said that after so long, the summon goes back where it came from," Naruto explained with a shrug.

"...Have no idea how to do that, don't really want to either," Leviathan said after a moment of thought, "Besides, I may not know measuring systems, but I do know I can swim around the world and be back in a week, assuming I don't get a little lost," He pointed out.

"Don't you want to go home?" Naruto asked curiously.

"Nah. The only ones that'll probably miss me are Ziz and Behemoth, and they probably won't notice I'm gone for a long while. And a century or two vacation could do me good," Leviathan answered easily, rubbing his head with his tail.

"Okay...well, I think the pervert is going to be useless for the rest of today, after that beating you gave him," Naruto stated awkwardly/ "I guess we head home...you think you can shrink down again?" Naruto asked, looking over at the horned sea monster...only to find he had already shrunken to the size of garden snake. A really long one, but still just as thin.

"Will this do?" Leviathan asked with an incredibly high pitched, squeaky voice.

"..." Naruto just stared down at him for a moment, taking in the image.

"What?" Leviathan asked cluelessly.

"BWHAHAH!' Naruto hollered, rolling on the ground ,clutching his stomach, "You-your voice!" He tried to get out between laughs.

"Huh? What about my voice?" Leviathan asked in confusion, "Do I have something stuck in my throat? Did somethink not shrink down with me?"

"You...you sound like a goddamn chipmunk!" Naruto roared with laughter.

"Screw you, Uzu! And what the fuck does a chipmunk have to do with my voice?!" Leviathan protested, his voice even higher when yelling, making Naruto laugh even harder, "STOP LAUGHING OR I'LL BURP MY TOXIC BREATHE ON YOU!" Leviathan yelled in warning, fumes coming from his mouth ominously, still not getting what was so funny.

"Okay, okay, I'll stop!" Naruto said in surrender, getting a few giggles out of his system. Leviathan just huffed as he slithered up Naruto's arm sleeve, curling loosing around his neck under the high collar, "Try not to squeeze," Naruto requested, blinking as he felt Leviathan go very lax on him, "Hmm, must be a fast sleeper...," He mused before heading home.

Meanwhile

Kurama, aka the Nine-Tailed Fox, watched the meeting between Naruto and the Leviathan with a sweat-drop of his own, "Who and what the Makai did we summon?" He asked in confusion before shrugging, "Oh well, at least I don't have to worry about the brat dying on me any time soon. Huh..I wonder what would pop up the next time he tries to summon with my chakra..." He said, rubbing his chin in thought before shrugging and going back to sleep.

End of Chapter

This was originally going to be part of another fic, but Leviathan's character grew, pun intended, to the point where it was simpler to give 'Naruto Summons Levaithan' its own story. And yes, this is the biblical Leviathan- which is either 300 miles long or is something enoguh to swallow something 300 miles long, the passage is a bit vague on that detail.

Still, yes, Naruto has summoned the Primordial Sea Monster, due to Kurama's chakra screwing with the jutsu. While Kurama and Jiraiya were both aware that could happen, neither of them expected sometihng this crazy to happen.

And, as you can all plainly seen, Leviathan is very much out of touch with Naruto's era/world. And while he is ancient and full of knowledge, that doesn't mean his memory and knowldge is perfect.

And funnily enough, he not only has taken a liking to Naruto, or is just really curious about him and this place, but is also convinced that Jiraiya is a pedophile that takes advantage of parentless children...and as I wrote Leviathan's reactions, I realized just how sketchy Jiraiya and his actions sound out of context.

Also, I forget, to be honest, how the nature of the returning aspect of the Summoning jutsu goes- do they just run out of the chakra that is keeping them there or do they just return when they want to? Either way, I have an explaination prepared for Leviathan's prolonged pressence.

Pairings, at the moment, are undecided. However, this fic is more humorous than anything, so don't feel afraid to make suggestions for future things to happen. Like Behemoth and Ziz showing up, or other creatures that may or may not be related to Christianity, Judaism, or Islam.

Until next time, I hope you've all enjoyed this, and hope to see your comments, reactions, an d suggetions in the reviews.

Now Review before Leviathan breaths on you!
