Disclaimer: I Do Not Own Naruto Or Dragonball Z
"So this it." Floating in the expanse of space or maybe it was the afterlife, Naruto Uzumaki knuckle headed ninja of the leaf, Ex-container of the Nine-Tailed Demon Fox closed his eyes too tired to do anything else. He had given everything he had in the final fight against Kaguya; the war had been won and his friends safe back home. He could go peacefully knowing he had accomplished what he needed. "Hopefully I can meet Mom and Dad in the afterlife."
Unbeknownst to Naruto as his unconscious body drifted further into the dark expanse he began to change. Bones and muscles grew smaller, old scars shortened as his body shrunk and a brown furry appendage sprouted from his lower back.
Far away on an Unknown Planet in Other World, the Supreme Kai felt an unknown energy signature appear. "Kibito do you feel that Power?"
Kibito loyal assistant to the Supreme Kai focused his senses searching out what this master felt. "The one that suddenly appeared? Yes, I do master, but I don't see how a Power level like that warrants your attention."
"Don't just focus on his Power level Kibito. Feel his life force." The Supreme Kai instructed his assistant. As Kais, they could feel the life energy from all beings in the universe. From the smallest insect to the strongest warrior if they concentrated their senses.
"Life Force? I can feel it fading, but I don't understand Sir. What does that have to do with why it should matter to us?" Kibito asked confused. There were millions of lifeforms died a day in the universe. Why would his master care about this one?
"The age Kibito. Can't you feel it's age? So young yet so strong." The Supreme Kai said still focusing on the strange new life. Standing from his chair, Supreme Kai began gathering his energy for a teleportation. "Kibito we are going to see what this energy is following me."
"B...But master!" Teleporting seconds after the Supreme Kai Kibito appeared beside his master in the vast expanse of space. Staring down at the small black and blonde hair boy drifting through nothingness he frowned. "Master he's a Saiyan. Look at his tail."
Just as shocked as his assistant Supreme Kai reached down and grabbed the brown appendage. It was true, the black hair, the tail, and even the power level felt similar to what the Saiyans had when they were still alive. "How Peculiar. Where did you come from young one?" The strongest Kai asked the child rhetorically. "A power level so high for such a new life. I've only seen this once before Kibito."
Kibito nodded a hardened look crossing his face. Reaching for the boy he hardened his resolve."I remember Supreme Kai. The King made the right choice a boy with that strength could have wreaked incredible amounts of damage upon the Universe. We must do the right thing here as well."
"What! No, Kibito that is not what I meant. What happened years ago was the result of one man's fear. With the right training, this boy could be one of the greatest fighters to live." Picking up the Saiyan child Supreme Kai smiled at the small humanoid alien. So many years of feeling countless lives be snuffed out and lost to the sands of time. Helping one grow would be quite the change. "Kibito let's go we are returning to Planet Kai."
"Master!" Kibito exclaimed aghast. "Supreme Kai Sir, the Sacred World of Kai's is just that sacred. We can't bring a mere mortal there it would be complete sacrilege. This boy while powerful is still not a Kai."
"That may be Kibito, but I feel that one day this young Saiyan will be special."
The Supreme Kai teleported along with Naruto back to the Sacred World Of Kai's. Creating clothes and a crib for the small boy Supreme Kai set Naruto in the crib after dressing him in simple shirt and pants. "Kibito will be here any second and won't give in too quickly about you being here young one."
Placing a hand on Naruto's head, Supreme Kai looked into the young boys' mind. Removing it seconds later Supreme Kai frowned "Naruto that is your name, fitting yet that is all I can see."
Popping into existence Kibito frowned at the sleeping boy. Turning to his master, he stayed silent upon seeing the Supreme Kai in thought.
"Kibito meet Naruto. I know you disagree, but he will be staying with us. When the time comes, we will train him ourselves as well as find another Saiyan to help."
"Master the only Saiyans left work under Frieza and the one on Planet Earth thinks he is a human. You are the Strongest of all Kai's what makes this mortal worth your training. A power level that high as an infant is quite the feat, but that still doesn't justify."
"Silence! He will stay Kibito it is what I wish." Supreme Kai levitated the small crib moving it to sit in the shade underneath one of the trees. "As I said before, one day this child will be special, Why I do not know yet. Now please would you make some tea."
Watching from his crib, Naruto smiled in his mind at the kind stranger who helped him. He didn't know why he was an infant once more but Kaguya last words resonated through his mind. "The war may be over, but I know better than to leave someone of my blood in a world like this." Reaching a hand out he grabbed the shorter light purple stranger. "She must have sent me to a new world or even universe. Kaguya was crazy enough to do it.
"Oh, you are up Naruto. You may not understand me now little one, but you are quite the special young fellow."
(4-Years Later)
"Hmm, his power level grew once again." Supreme Kai thought watching as Naruto sparred with Kibito. The once infant Saiyan boy was now an unusually strong five-year-old even for the Saiyan race. Watching as the young boy's power grew with each punch and kick thrown. "The same as every other spar, His power grows with each passing second."
"Come on Kibito stay still no fair." Growling Naruto sped up the speed of his punches beginning to swing wildly at the larger fighter.
"Naruto calm down you're attacks are getting sloppy," Kibito Commanded grabbing both Naruto's hands kneeing the child warrior in the stomach. Gasping Naruto dropped to the floor clutching his ribs. He hadn't even seen Kibito move. "You do this every time, boy."
"I'm sorry Kibito." Naruto apologized once he got his breath back. He didn't mean to lose control like that it just happened. He would be fighting, and then he would get faster and stronger but lose focus. "I can't control it. I don't know why."
"Control it? Control what Naruto?" Supreme Kai asked reaching out to feel Naruto's power level, not finding any irregularities just the slight rise that always accompanied Naruto's spars. "What is he talking about?"
Hesitating to answer Naruto looked away. His ninja mindset not comfortable revealing such weakness even to his allies. "No stop, I'm not a ninja anymore." Looking back at Supreme Kai and Kibito who were both staring expectantly but patiently Naruto sighed. Maybe these two could help him figure it out. They were strong or at least Kibito was he hadn't sparred with Supreme Kai yet. "When I'm fighting I start to feel more powerful and my stength rises but the higher it gets, the more control of myself I lose. It's as the power goes right to my head and all sense flies out the door."
"It seems your mind cannot cope with the amount of strength you have Naruto." Supreme Kai explained. "Mediation will help, go home and shower then come back we will begin today's training early."
Nodding Naruto flew away to the small hut Supreme Kai had created when he was old enough to live by himself. Stripping out of his blue and purple training Gi Naruto entered the small shower. It was weird being an eighteen-year-old man in mind but a child in body. Baths and going to the bathroom since being sent to this world was a complete embarrassment for him.
"Supreme Kai Sir, what do make of this development?" Kibito questioned his master. He had noticed since Naruto training began the Saiyan child grew leaps and bounds in power. "If he keeps this up."
"He might grow to be the strongest fighter in the universe. Even rivaling the beast I sealed so many years ago," Supreme Kai said giving a moment of silence to his fellow Kai's who perished in the fight.
"You really think he could become that powerful Master. No one in millions of years has come close to that monster power." Kibito knew Naruto had potential but for Supreme Kai to compare him to that monster. Eyes widening in terror Kibito turned to where Naruto flew.
"Don't even think those thoughts Kibito!" Supreme Kai snapped glaring at his assistant. "Naruto is kind hearted to a fault. While he may have Saiyan blood and Pride, he could never become what Buu was."
"Right Master."
Closing his eyes, Supreme Kai felt out two distinct energies. "We need to push forward his training. If he has this much potential, then it is our job as his caretakers to help him grow into the great man he is destined to be. Even if we need outside help."
Catching onto what his master was hinting at Kibito shook his head. "I said before the two Saiyans left would be no help. One still doesn't know who he really is and the other works for the evil Frieza. Neither would be a very smart choice to help train young Naruto."
"That is true Kibito, but I never said the Saiyan we would enlist had to be alive."
