This kind of talk Kyuubi's talking
The deep red fur of the gigantic fox ripples indignantly. His furious eyes glare down into the impassive blue eyes of the small figure blocking his path. "Kyuubi, this is a bad idea," the man states, his arms crossed over his chest.
The giant fox roars, "Get out of my way, Guardian! I will not allow this to go unpunished!" His roar blows the man's blue cloak back but his hood remains in place, shadowing his face.
"You'll regret it if you go, Kyuubi," the man says calmly, not intimidated at all by the raging demon fox. "But I won't stop you if you refuse to listen to reason."
A dark chuckle erupts from the massive beast. "Just watch as I decimate that puny village, Guardian. You'll see nothing like this ever again."
The man raises an eyebrow and says with just a hint of concern in his voice, "Yes, I'm quite sure neither of us shall see anything like it again in our lives." The man slowly walks out of the demon's way and holds his arm out to gesture him forward. "Do as you will, but you're making a mistake."
The red fox demon rumbles, "The only mistake made was made by those arrogant mortals."
The man mutters darkly, "Yes, pride comes before the fall; a lesson I wish you all would learn."
The nine-tailed demon stomps past him, tails smashing trees and crumbling mountains in passing. The man stares after the demon for a few minutes before shrugging, "Well, might as well see what happens!" He trots after the huge fox, following the trail of destruction.
A Few Days Later:
"Send out the next wave!" a ninja orders with deep scars covering his face. Miles away the legendary Kyuubi the Nine Tailed Fox snarls, swatting at the annoying ninja attacking him with hopes of slowing him down.
The fox mutters, though it sounds like growling to the humans, "Foolish gnats, hardly worth my time." Hundreds of small elemental blasts pelt his fur from the surrounding ninja. His tail smashes a battalion, a second tail sending trees flying several miles towards the village, barely missing the wall.
"Belay that order, Ibiki," the Hokage says with his blonde spiky hair visible without his ceremonial hat on. "There is no use in sacrificing more lives to that beast." He carries a small baby in his arms. The blonde baby is a mirror image of the Hokage. The Hokage jumps from the wall and breaks into a sprint through the trees.
The blue-clad man chews on an apple as he watches from a distance as the Kyuubi tears apart the Leaf Ninja effortlessly. "You're wasting time, Kyuubi, stop playing around before they come up with a way to beat you," he mutters to himself between bites. "Humans are too resourceful to be underestimated."
A large cloud of smoke erupts a mile from the Kyuubi's location leaving a giant toad as it dissipates. The Hokage stands on the toad's head with the baby in one arm. "The Kyuubi, eh, Minato? Looks like you bit off a little more than you can chew this time," Gamabunta comments, smoking his pipe.
Minato looks down at the toad solemnly, "We don't know why it's attacking, but this will be our last battle together." The toad notices the baby and sighs.
"You're going to do That," he grumbles. "That not a thing that should be done to your own son."
"He'll be seen as the hero of the village," says Minato confidently, dabbing a paintbrush against the baby's stomach writing a small seal. The baby gurgles happily.
The toad croaks, "You have too much faith in that village of yours." He pulls out a building sized flask of sake and gulps it down. Wiping his lips, the toad puts the flask away. "But, let's get this over with."
"Thanks, Gamabunta. I just need you to keep it busy for a little longer. I'm almost ready," he explains.
An older white-haired man leaps from a tree onto the toad boss's back. "Jiraiya!" Gamabunta says harshly, "Talk your student out of this insane plan of his."
Jiraiya shakes his head slowly, "If there was another way, he would have thought of it. Hello, Minato."
"Take care of my son, Pervy Sage," Minato says as he stares at the nearing fox. The toad Sannin nods at the last request. "Tell Sarutobi that I'm sorry he has to come out of retirement," the young Hokage says, handing the baby to his old teacher.
Jiraiya takes the baby and notices the seal. "Does he have a name?"
Minato thinks about it for a few seconds than shouts over his shoulder, "Naruto! His name is Naruto. Make sure he's seen as a hero, okay?"
The Sannin jumps from Gamabunta's back and waves goodbye, "You got it, kid."
"Now, Gamabunta," Minato says seriously. He begins the long string of hand signs. The toad sighs as he draws his short katana. Without another word the colossal toad leaps at the fox. He twirls and jumps over the multiple tails, protecting the man on his back.
Kyuubi roars and lashes out at the toad, leaving a large scar over his eye. "Hurry up, Minato!" Gamabunta calls. He twirls his sword and stabs Kyuubi's paw before leaping into the air, sheathing his short blade. The toad makes a hand sign and hits his stomach, water missiles launching from his mouth at the fox. The approaching tails are slapped away by the water missiles. The fox demon lets out a low growl, jumping at the toad, meeting him in midair.
Minato continues the hand signs faster, his hands a blur. He uses chakra to stick to the toad's back as the two titans clash. Surrounding ninja shoot their tiny jutsu at the humungous beast, distracting him enough for Gamabunta to get in a few good strikes with his short sword. The angry fox drives Gamabunta back towards Konoha, the boss toad's blade barely blocking the multiple tail strikes. "Hold him, Gamabunta!" the Hokage yells as his flurry of hand signs comes to a close.
The boss summons plunges his sword into the Kyuubi's left shoulder and holds back his snapping teeth with his feet. "Hurry up before he gets toad legs for lunch!" Gamabunta grunts, struggling to keep the beast still.
Minato glares down into the Kyuubi's eyes and shouts, "Eight Divination Signs Seal Style!" The Kyuubi's eyes go wide as his body weakens. Gamabunta pushes him down onto his back, digging into his shoulder harder with the sword. The red chakra flows like a stream from the giant demon and flows into the seal on Naruto's stomach as Jiraiya holds him from a safe distance away. The Kyuubi lets out a final ground shaking roar and goes still, his body fading into nothingness as the last of his chakra is sucked into the glowing seal.
Minato glances over his shoulder weakly as the Shinigami slowly drags the Kyuubi's soul to the seal and pulling on Minato's in the process. He whispers, "Goodbye, son. Forgive me." His body collapses on Gamabunta's back, his soul devoured by the voracious god of death.
Hopping down from his perch in a tree, Guardian sighs loudly. "Stupid mistake. He should have known better," he says angrily. "Now I have to clean up his mess as usual. I don't know why I still help him."
The Kyuubi roars as he slams against the thick bars on his new prison. "You won't keep me locked in here forever! I will break free!" His eyes glow in the dark sewer as he lies down on the cold floor. "It's only a matter of time. When it happens, I will be ready." The Kitsune King curls into a ball, closes his eyes, and falls into a deep slumber.
Konoha ninja rush around the village with their wounded and supplies for repairs. Nobody notices when a blue-eyed stranger enters the village, covered in a dark blue cloak. The man watches the Hokage Tower's window to see Jiraiya handing the newborn baby over to the Third Hokage, shaking his head sadly.
"How the mighty have fallen," he whispers as he watches. Glancing around at the panicked village, the man says with a smile, "Well, someone has to keep an eye on the old furball. It might as well be me!" He disappears into an alley unnoticed.
