Disclaimer: I do not own Naruto except for a few things that was not created by Masashi Kishimoto.

This fanfic was inspired by "Demonkid"'s 'Kireki tenshu' and Yuyu hakusho of Yusuke and Raizen and fanfics where Naruto transform into a 100 feet creature.

Chapter 1: A dorment thunder god awakens!

-----------------------------------------------------------------------------------------------------------------------------------------------

Jiraiya dropped Naruto onto the ground. Slowly, Naruto began to regain his consciousness. He began to get up.

Naruto woke up groggily and looked around his surroundings. Where was he anyway!? Before fainting, he was trying to summon a frog but instead he kept summoning tadpoles! He kept Summoning and summoning and soon he collapsed from chakra exhaustion.

"Get up!" Naruto jerked around to see his recent mentor Jirayia.

"Huh? Where are we?" Naruto asked. Looking around, there was what seemed to be a line of bushes. There were a few trees here and there. He took a look at Jiraiya's face. It was one of seriousness.

"Get up." There was no humor or behind it. Naruto quickly obeyed, knowing that Jiraiya wasn't a man to cross. He began to speak. "The training ends today... If you don't want to die then figure it out yourself."

"Wh-what?" Naruto was perplexed. He had just been taught the summoning jutsu, which he still needed to perfect. Why was Jiraiya ending the training now? His teacher slowly raised his hand and, using his finger, gave a poke to Naruto's forehead. Then he flew through the line of bushes and saw what was on the other side...

Nothing. It was simply a gorge...One of the last place Naruto wanted to fall.

"AAAAHHHHHHHHH!!!!"

And fall he did. "AAAAHHHHHHHHH!!!!" Jiraiya simply listened, hearing his pupil's scream slowly fade away.

'Now...We'll find out shortly whether Kyuubi's power that was granted to you is really a blessing...or a curse!' Jiraiya thought.

"AAAAAAAAHHHHHHHHHH!!!!" Naruto was still falling. Seeing a rock ledge come into view, he summoned some chakra into his hands. He grabbed it, but to his dismay, he slipped and continued to fall.

'It's useless Naruto...The rocks are too slippery from the waterfalls. In addition of your falling, you're not going to stick with a little bit of chakra...' Jiraiya thought after seeing Naruto's incorrect methods of saving himself. 'Naruto... You have no choice... You have to rely on the Kyuubi-s chakra. Use the key... this time from your end!'

'At this rate... At this rate... I'll surely die!!!' Naruto was in a full panic. He was hurtling down a waterfall and would soon meet his demise when he reached the bottom of it. He was sweating at the thought of him dying. All of a sudden, he remembers something about his summoning training.

(Flashback!)

He removed hand, only to reveal a summoned tadpole. A useless, tiny tadpole that flopped in front of him. 'Kuso, not again...'

"NO!!! HOW MANY TIMES DO I HAVE TO TELL YOU, YOU IDIOT!!!" Jirayia scolded him. "RELEASE ALL OF THE CHAKRA IN YOUR BODY AS IF YOU'RE ABOUT TO DIE!!!"

(End Flashback!)

"Die..." Naruto said.

'Die...'

'D...'

All of a sudden, time seemed to stop for him. Everything slowed down and he felt as if he was being pulled into another world.

Kyuubi's Cell

"Huh!?" Naruto swore that it looked like he was in Konoha's sewer. He was kneeling down. 'Where the hell am I? And how did I get here?'

"OOOOOO" A sound emanated from somewhere down the hall. Naruto stood up and followed the noise.

'This feeling... It's that chakra...' When he went through a passage, he looked up and saw a barred gate. On the gate was a piece of paper with the kanji 'Seal' seal written on it. Slowly, a pair of red eyes opened.

"Ugh!!!" 'Huge... What is it...?' Naruto thought. But the beast inside the gates thought differently.

"Kid... Come... Closer..." Naruto felt like he was pulled in but mostly letting curiosity get the better of him, slowly approached the gates, the gates that kept the beast from breaking free and escaping. Suddenly, several large claws went through openings between the gates.

"WAAAAH!"Naruto quickly backed away, intent on keeping himself from getting slashed into many pieces. The creature scowled.

"Damn you...I want to devour you human but... this blasted seal..."

The answer then dawned upon Naruto. Behind the gates was the demon that was sealed inside of him. It was behind these gates that the creature that kept the children from playing with him lived. Behind these gates was where all of his misery started.

"Y...You're... the Kyuubi!" 'I get it now... That red chakra... It was his...' Naruto was standing in front of the very demon that could have destroyed Konoha, the place that barely scraped by his standards as a home.

"Brat...What business do YOU have here?" Kyuubi demanded. Naruto, remembering that, in the outside of...well, whatever this place is!, he was hurtling down a waterfall!

Naruto looked into the eyes of the fox, donned with face of determination.

"Hey fox!! I'm letting you stay in my body, so... instead of paying me imaginary money, lend me your chakra!" There was silence. Silence so quiet it was unnerving. Then the booming voice of the Kyuubi shattered the fragile silence.

"GWAHAHAHAHA!!! If you die, then I die too eh? To threaten me like this... You got some nerve!"swirl around Naruto's "Alright, I'll lend you my chakra." The Kyuubi gave off an evil grin. "But for coming this far and having the guts to threaten me, so in the process I'll awaken something dorment that has been your vain, in generations after generations, power that hasn't been seen for thousands of years"

Naruto stared at the fox with confusedness

"Hey, what do you mean your going to "awaken" my hidden power? is it a Kekki genkai?"

"Well...It has been more then a thousand years and the more your ancestors mated, the more his blood started to dissipate and two...", He grinned mischievously. "... I think its much better then just an old reguler bloodline..."

Enjoying the confusment and interest in the blond's face he continued."Heh...Be thankful that I'm here...Boy..." At this Naruto scowled in distaste. "...Or else the "The Atavism of the Hiraishin"(1) will be gone for good."

"The atav...er...wha?" Kyuubi sweat dropped and growled at the boys idiotic nature.

"Grrrr...I'll tell you after your transformation!" He snarled/roared at the blond. His demonic chakra spiked with killing intent that made Naruto shut up.

'Wait, what 'transformation?' Pondered Naruto and soon fear started to cloud his mind. 'Is he going to make me a fox demon?' Naruto prayed not. Memories of the villagers calling him "Demon" or "Hell spawn." still haunted him.

Noticing fear flashing in the child's eyes he explained. "Don't worry, I won't turn you into a weak version of me..." At this Naruto sighed in relief. "...Instead..." Kyuubi gave him a foxy grin and slowly began to inject his foul red chakra to the orange wearing lad. "...You'll become something greater or less then me, now go and take the chakra"

The red chakra began to legs. Slowly, it wrapped around Naruto's body. But as the chakra seeped within him, PAIN and volts of lightning started to erupt within, and out of him.

"AAAAAAAGGGHHHH!!!!" He bends over in pain. The pain was EXCRUICIATING!!

"W...What...WHAT WAS THAT?" He gasped out in anguish.

"Eeerr...Oops?" Naruto sweat dropped and glared at the demon with his pain-wrecked eyes. "Damn it Kyuubi! WHAT-DID-YOU- DOOO!?!?"

The fox grinned cheekily at him. "Don't worry brat, this is just the first sequence of your rebirth, you'll thank me for this later"

Naruto glared at him for the last time before screaming out his agony.

Kyuubi watched in interest as the boy's body began to pulse, twitch, grow, convulse and then exploded with tremendous amounts of chakra and lightning..

"Rise Naruto...Rise" He mystically called out to him, his demon edged voice was filled with dark foreboding. "...Rise and show the world of the diabolical power that resides within you..." He stopped and thought for a moment.

"And don't forget to mention me, the Kyuubi no youko!! The guy who actually bothered to release your fucking...!" But his demonic voice was drowned out by the sound of intense thunder and lightning.

---------------(Real World)-------------

Jiraiya was getting worried as he waited patiently for a kind of explosion or a loud booming voice of a frog.

'Come on...It's been at least 3 minutes or so, Why haven't he summoned a frog like Gamabunta, who was large enough to stop his fall?' Deciding to take action, shaking, he walked to the gorge edge and peered at the abyss for a full minute before taking his head back in.

'Oh no...Please don't tell me...' His heart began to beat fast with guilt and fear. "Minato...Kushina..." He whispered as a single tear started to form around his eyes, a welting feeling was clenching his chest. "Please tell me...that I did not just kill your only son..." He whispered.

'...And my only godson...'

Another minute passed by...

"Sarutobi-Sensei is not going to happy about this...not happy at all." He gulped at the idea of his teacher choking his neck screaming in outrage. Accepting this, he got up and started to walk to where his old mentor should be.

But an earthquake ended his guilt trip.

A massive earthquake that was strong enough to make mountains and buildings to crumple

Quickly using chakra to attach himself to the ground to prevent falling, he franticly whipped his head around to see if the girls from the waterfall were injured.

Sighing in relief as he saw them whole and well, only screaming and grabbing their equipment and away from the sudden danger.

Suddenly a sound of a massive explosion reached his ears, and it was coming from the gorge.

'Is it the Kyuubi!?' He thought in horror, if Kyuubi were to be free because of the boy's death it would mean two things. Not only the Kyuubi will destroy...stuff, but also he, the toad sage Jiraiya, would have a lot of beatings in heaven or hell.

'NOOOOO!! Come come paradise must live on!'

Recovering from his worries and regaining his confidence back, he slowly walked to the cliff and was about to take a peak of what's accruing down...

"WOOOOOAAAAH!!!!"

...If it wasn't for a pillar of gold/yellow light that shot out of the seemingly endless pit and into the sunny blue sky.

Jiraiya stared at the pillar with fascination and terror, he could actually feel the power that was within it!

And he was sure that the others had felt it as well.

(Konoha)

Almost everyone was screaming. The earthquake caused most civilians to be frantic, children outside or inside the academy were all crying. But what really caused the Shinobi's and other ninjas to freeze as a powerful flare of chakra, and it washed over them like an ocean wave.

Sarutobi, the 3rd Hokage was shaken, his brow was already forming sweat bullets. He wasn't just worried about his people, but the sudden flare of a terrifying force.

'Hmm...This is...truly terrifying indeed.' Thought a quivering Sandaime.

KONOHA BORDERS, UKNOWN MOUNTAIN AREA,

Two figures were facing each other; both of their right hands were emitting lightning and sounds of one thousand birds.

One figure was 4'11; he had black/dark blue hair that ended in duck ass style spikes. He wore a chin high T-shirt with a red/white fan on the back. His pants were white shorts that reached to his knees and had black leather straps on his shins(You know how Sasuke looks)

In front of him was a tall man at the height of 181 cm (roughly 6 ft. Dunno how tall Kakashi is...)

They stood there, unmoving and silent. They were planning to strike each other before a tremendous pillar of chakra erupted through the sky.

Sasuke, who was so focused in his training, almost missed the sudden chakra and tried to stop his assault.

"AAAAAH!!" Kakashi screamed in pain as his own student and jutsu has grazed his side. Oh the irony of being hit by your own original jutsu...

"Uh, Kakashi! I didn't mean to-" But he was interrupted by a hiss "I'm fine" from his injured teacher who was holding his bleeding ribs.

Kakashi and his prodijy student just gazed at the pillar with worry and said nothing else.

(-----Border between Suna and Konoha------)

A Kazekage lay dead in the sand along with his guards. Two figures above them were now staring at the pillar, ignoring their victims

Insane yellow eyes with slits stared at the gold/yellow tower of chakra and couldn't help but to shiver at the pressure it was giving.

Orochimaru held his sleeve just so that the blinding light was shield from his slightly insane gold eyes.

Licking his lips in a disgusting way, he said one word...

'...magnificent...'

(Back to Jiraiya)

The massive pillar of light, or rather, the pillar of gold chakra continued to flare it's energies to the heavens for minutes, before it started to shrink into small wisps of the spectaculer tease.

Jiraiya stood still for a moment, his eyes were in shock. But slowly and shaking, he got up...only to be knocked down by a sudden pour of wind and rain.

"Aaaaaah!!" He tried to get back up, only to be hit by a stronger pour of rain and wind.

'Kami-Sama! Where the heck did this storm come from!?' He ponderedas he look around his surroundings. Due to the massive combo amount of rain, wind and lightning, it was making it difficult for him to see and hear. Back and forth was the Gama-Senin movement as the storm kept knocking him down.

The sky maelstrom continued for minutes, but much to delight, the storm faltered for a bit so he can see the damage and gaped.

Many trees were decimated, many were now bended in strange angles, some were burnt from the lightning and others were knocked to the roots by the wind. Seeing this, he was now a bit scared to see what's above him.

And he tilted his head up and gasped in shock as he saw the sky.

Just through the endless rain and lightning was a large dark hole in the sky. (Like in DBGT where android 17(s) open up a portal in the sky, which connects to hell and earth)

The dark, cloudy hole in the sky was at least a 100 miles wide and 100 miles of...well, just a perfect 100 mile circle in the sky.

But to Jiraiya's relief, the dark abyss of a hole started to shrink and a small light started to appear in the middle. The storm was slowly dissipating leaving a dark, wet, destroyed atmosphere along the wake.

But his worries were not finished as an inhuman roar echoed from above. A soggy, irritated Jiraiya had enough as a dark shadow loomed above him. He prayed in silence and tilted his head backwards. His aged face was calm and neutral, then slowly molded to a expression of shock, amazement and a slight hint of "WTF!?".

"Oh...Kami...Sama..."

Just hovering above him was a unmoving and hulking creature, a MASSIVE creature. It has to be a height of a mountain at least!

The Beast stared at him with pupiless gold eyes and said two words that made Jiraiya stare at him with disbelief.

"Ero-Sennin..." It grumbled. gruff, but still bearable.

The toad sage stared back.

"Naruto...?"

The two beings continued to stare at each other, until...

"Ero...Sennin...Ero...Teme...ERO-TEME!!!!" A look of rage crossed the creature's face and let out an ungodly roar as it swooped back down to the earths crust.

"OH SHIT!! Bad Naruto! Bad boy! Bad, bad little-I mean big boy...!" He quiet down as the Earth trembled beneath him as the beast landed in front of him.

He found himself staring at his new student...who was not himself at the moment

"Ero-Sennin!" The behemoth said without opening it's mouth. The voice was of a 12 year old with a demonic edge to it.

Jiraiya kept staring and staring until he pinched his nose in fierce annoyance.

"Oh fuck me sideways..."

(Unknown dimension)

A man in spiderweb bed filled bed has finally opened his eyes from a thousand years worth of sleep. Groggily, sleepy eyes narrowed amusingly. Thin mouth forming to a odd, dark smirk

"So...After thousand of years a Hiraishin has awakened..." The man chuckled as he went back to sleep, but not before thinking.

'Don't disappoint me...grandson..."

A/N Sorry if it's crude, but I had this idea recently and had to write it

(1) "The Atavism of the Hiraishin" originally supposed to be "The Atavism of Raijin" but i decided against it.

This new fanfic is kinda like Raizen and Yusuke of YU YU HAKUSHO.

An atavism is a real or supposed evolutionary throwback, such as traits reappearing, which had disappeared generations ago. Atavisms occur because genes for previously existing phenotypical features are often preserved in DNA, even though the genes are not expressed in some or most of the organisms possessing them.

Kinda like Yusuke and Raizen's sort of sequence.

Sorry for the fans of "Hiraishin No Naruto" but i really had no ideas to how to continue

REVIEW PLEASE
