I don't own Naruto or Dragon Ball Z

Naruto Z

Kai's allies

2,000 years before Dragonball

On the guardian lookout a blond haired man with a white cloak and the Kanji for Guardian was quietly meditating "there is a disturbance within the earth; but I can't pinpoint it," said the blond.

A red skinned man about seven feet all muscle runs out to the blond "Master Naruto Namikaze, we have received word from Dai Kaioshin," said the man in a heavy voice. Naruto eyes suddenly "I have a bad feeling about this; what is the message Keno?" asked the blond. The man gives Naruto the letter "it seems the Kai's are fighting a monster; they have already lost North Supreme Kai to death and the South Supreme to being absorbed," said the man.

"Are they on earth?" asked Naruto. He bows "yes sir they are fighting south of a small village; the villagers have fled from the fighting. Naruto nod his head "I will go and assist; I want you to stay here," said Naruto as he disappears in a white flash.

In the small village the three Kais were getting the crap beaten out of them. One was pink and had white hair she had the most injures next to him was a purple skinned man with a white Mohawk and on the other side was a chubby man with orange skinned and he seemed to be faring better than the others.

Fighting them was a bulking pink monster with an appendage coming out of his head. The pink monster charged the three and was heading towards the female Kai. Naruto disappears in a flash then goes through some hand signs "Fire Blitz," said Naruto as he fire a fire beam out of his hand but is rammed by Buu sending him back to the other side.

Naruto struggles to get up "well that could have gone better," said Naruto as he finally manages to stand. Naruto spits out some saliva and blood; he turns his head and sees the female Kai trying to stand. Naruto teleport over to her "are you alright West Kai?" asked Naruto.

The female Kai raised her head "Naruto," she said weakly. Naruto picks her up bridal style and carries her to the purple Kai "Shin you must take West Kai and leave; head to the Lookout," said Naruto.

The Kai takes her "what about you; you can't hold him off by yourself," said Shin

The rotund Kai walks up to Naruto "he won't be alone," said Dai Kaioshin. Shin looks at the two "very well be careful," he said as he flew up with West Kai heading north to the tower.

Buu attacked the two as Dai Kaioshin fire out a beam splitting Buu to about fifty pick cube. Naruto seeing his chance fire at powerful energy wave destroying all the cubes. Naruto lands on the ground breaths hard and tries to sense Buu "did we win?" he asked.

Naruto turns his head upwards "shit we can't beat this thing," he thought as he see pink clouds reforming and Buu finally appears.

Naruto and the leader of the Kai's charge the monster but get beaten back. A pink part of the monster appears behind Naruto and jumps up on him.

Naruto turns his head and jumps away but his friend his comrade was not so lucky as he got absorbed. Buu changes in to a fat pink creature "Buu," it says innocently.

Naruto raises an eyebrow "I have only one choice, I must seal the monster," he thought.

He goes through hand sign "seal jutsu: purity seal," said Naruto as his hands glow pink and part of the earth surround Buu and encases it in rock and earth. The earth turns pink around and a shell is finally encloses with Naruto energy "that will keep him from escaping," thought Naruto as he passes out.

Later Naruto wakes up in a white room "must be on the lookout," he thought. He get out of the bed and walks outside to meet with the others.

He gets there and sees the two Kai and his student Keno looking at him "Naruto you alive," shouted the female kai as she ran up and hugged him.

"Thank you Guardian Namikaze," said Shin.

Naruto has a sad look "the cost was too great," said the Guardian as he turns to his student "Keno come forward," said Naruto.

The tall man walks forward and kneels "master what can I do for you?" he asked.

Naruto smiles "raise my friend; you are no longer my student but my equal raise and take you place as the Sandaime Guardian of the Earth.

The tear come down "thank you my friend," said Keno as Naruto disappears never to be heard from again

Over the centuries war and battle have been fought between good and evil. Watching these events Naruto saw much of the world as a traveler and mystic and his name passed on as a myth.

Current time in the middle of nowhere

Naruto was meditating when he sensed a huge power level descending on the planet. "Looks like the protector Goku is not on planet," thought the blond.

He got up and put on his white and orange cloak with the word Ten Tails on it and flew in the direction of the two high powers.

He got to the location and saw the Z fighter hiding "I guess I will conceal myself," thought Naruto as he merges with the rock face. A circular ship flies over the heroes and lands on the ground.

The ramp opens up and about fifty shoulder walk out in military form and two aliens walk out one was half robot and was shorter then the second one who was taller and had horns coming out of his head "so this is earth," said the taller one.

"Yes I can't wait for that dirty monkey to come home and find his friends and his loved one dead," said the shorter one.

Well let get this genocide started Frieza," said the taller one.

"All of you purge this planet," said the one known as Frieze.

Naruto smirks and revels himself holding a jukebox up to his ear and dancing like a moron making Frieza get a tick mark on his forehead "hello I am Lord Frieza," he said.

Naruto puts down his jukebox "you say something?" he asked laughing inside at Frieza's face of pure rage.

"You pitiful human," he growled.

One of his soldiers check his device on his eye "his power level is fifty," he said causing them to laugh.

Naruto smirks and raises it a little making the number on the scouter to go up destroying it "what so funny," asked Naruto innocently.

The soldier was terrified "sir his level it was 500,000 before my scouter blew up" said the scared fodder.

The soldiers charge him but are destroyed immediately. Frieza steps up "well done warrior but you're still weak," said the tyrant.

Naruto shrugs his shoulder "you know that is a fifth of my power," said Naruto as he bring his power past his enemy's level.

On the cliff the Z fighter eyes widen and they start to shake from the power "what power," said a green alien.

A shots man with black hair sticking up clenches his fist "how is a human so strong; when I am the prince of Saiyan's?" thought the man.

Back on the field Naruto scratched his butt and yawned Frieza charges but can't land a hit "stop moving," said the Tyrant as he launch punch after punch but Naruto dodges "what else you got?" said Naruto acting bored.

Frieza flies up and a giant ball appear from his fingers "die human," he shouts as he launches his attack at Naruto who looks up and his eye change to a ripple pattern and the attack dissipates "that was pitiful," said Naruto.

Naruto disappears and summons a short sword and slices Frieza in half then blasts him with energy wave.

Naruto smiles "that was easy," he said as he flies down to King Cold.

"Well I must say that was impressive would you like to join me?" said the taller alien.

Naruto put a finger to his chin "no I think not," he said.

He puts away his sword and gets into a fighting stance. King Cold fire a beam but misses and falls down with a fist like hole in his chest in his back "how?" asked Cold.

Naruto smiled "simple I saw an opening and I attacked," he said

Naruto raises his hand "die," said the blond as he blasts the alien with nothing remaining.

Naruto turns toward a rock "come on out I know you're there," said the former guardian.

A boy with purple hair going down his head with a sword walks out with a scowl.

"You are you?" asked Naruto.

"I will tell you later but we have to wait for Goku to return," he said. Naruto eyes narrow "very well I will have his friends follow us," said the ninja

Naruto flies off to the Z warrior's position as he landed the warrior got into fighting position "if I wanted to kill you I have done it already; were going to wait for Goku so you guy can come if you want," he said.

The fighter get to a cliff and wait for two hours as a small Saiyan space pod lands a man with black hair and a red and black clothing walks out.

The man sees the fighter "hey guys how did you guy know where I was to land?" he asked.

A woman with blue hair points to the teen "this boy showed us where and this other defeated Frieza with no effort," she said.

Goku looked confused "really he destroyed Frieza like nothing?" he asked.

The mysterious boy turns to Goku "Goku I need to speak to you about something privately" he said.

Goku scratches his head "okay," he said.

The boy flies off followed by Goku a distance away. Naruto eyes narrow "I wonder what they are talking about," asked Naruto.

The blue haired woman looks at Naruto as he is meditating "Who are you?" she asked.

"My name is Naruto Namikaze and that is all you're getting out of me," he said.

With the boy and Goku

Let's get down to business my name is Trunks. I am the son of Vegita so I am half Saiyan and I am from the future; I would like to see your Super Saiyan state," he said.

Goku turned serious "very well," he said as he transforms. With a yell his black hair turns yellow and his onyx eyes turn teal.

"Wow unreal yes this will work," said Trunks. Goku still transformed looks at the boy "what now friend?" asked the hero.

"Now we both will become Super Saiyan," he said as he too transforms and his purple hair sticks up and turns blond and his eyes turns teal.

Back with the Z fighter

"Damn look at them go," said Yamcha.

Naruto looks intently at the two from the distance "interesting these Saiyan could be much stronger than me with time," he thought.

The blue haired girls turns to Naruto once again "were did you come from?" she asked.

Naruto sighs "very well I am from a village in the mountains were we have mastered Ki control," said Naruto.

Piccolo snort "I don't know anything that can stop an energy attack just by looking at it," said the Nemakian.

Naruto turned to the alien Rinnegan full blast "then you know nothing," said Naruto darkly.

Piccolo starts to sweat "what is this I can see my own death," he thought.

Naruto looks away "next time don't question people you don't know," said Naruto

Trunks and Goku

Trunk just put his sword away "good, I am going to warn you right now; three years from now south of South City two beings will attack and everyone you know will be dead," said Trunk.

Goku frown "what's the deal are they aliens?" he asked.

Trunk shakes his head "No their androids created on Earth; their creator is Dr. Gero of the Red Ribbon Army," said the boy.

Goku eyes widen "I faced him; you sure it's the same person?" asked the Saiyan.

Trunks frown "I am sorry but that is a battle you should have fought to the end; I know you are a good person but letting him live would be a decision that will come back to haunt you," said Trunk.

"Are they stronger the Frieza?" asked Goku.

Trunk balls up his fist "much; however it's two against one so I can't do a lot," he said.

"What about the others aren't they helping you?" asked Goku.

Trunk put his head down "they can't; three years the earth's Special Forces get in a horrible battle with these androids they die in that battle," said Trunk.

Goku's eye widen "Vegita, Piccolo, Krillin, Yamcha, Tein, Chaotzu; they all perish; Only my teacher and good friend Gohan survives but thirteen year later they get him too," said Trunks.

Goku eyes narrow "What about me do I die fighting the androids?" he asked.

"No you catch a Heart Virus; you die from that," Trunks explained.

Goku growl "damn I get killed off by a virus; I don't even get to fight darn it," he said.

Trunks looks up suddenly "wait you not scared even after everything I told you?" he asked.

"Well every challenge is scary at first; but we can't let them win," said Goku seriously.

Trunks smiled "Gohan and my mother were right about you; I have a cure for the virus so you can fight," he said

"You said your mother who is she?" asked Goku. Trunks blushes "it's Bulma," he said.

Goku's eyes widen "really, I never though Bulma and Vegita, I thought it would be Yamcha with her," he said shocked.

"Yamcha moves on and my mother falls in love with my father," he said.

Trunks turns his back "I better go and don't tell anyone of my heritage?" he asked.

Goku nod his head "right," he said as Trunk throws a capsule and a machine appears.

He gets in flies off back to his destroyed future as Goku turns to where his friends are "Damn what I am going to say to the others?" he thought to himself as his friends fly to him.

"So what did that boy want?" asked Tein. Goku smiles "nothing important," he said.

Piccolo snort "funny it sounded important," he said.

"You heard us Piccolo?' asked Goku. The Nemakian frown "these ears do more than frame my face," he said.

You better tell them the situation or I will," said big green.

"But you heard what he said," Goku exclaimed. Don't worry I wouldn't say anything to endanger your friend but we all must have a chance of surviving not just you," said Piccolo.

After a lengthy explanation "so that is it; everyone except Gohan dies against these androids. So we have to prepare for their arrival in three years," said the Nemakian.

Naruto sighs "that is the only we can do right now I suppose; I will meet you in South City in three years," said the former ninja.

"Wait come with me, Piccolo and Gohan and train near my house since you're strong I am sure you will make a great sparring partner," said the Saiyan hero.

"Very well if your wife will have me as a guest I can help with the chores," said Naruto. The four fly off to train for the arrival.

End first chapter

A/N: This will replace my ten tails saga. So I haven't figured out the pairings, it is going to be West Kai or Android 18. Next chapter will be the training and the encounter with the Androids. I showed the role Naruto played in Buu's sealing cause I left that plot hole in the last story.

Peace
