Naruto Xenoverse

Prologue

Unknown dimension:

Trunks was exhausted. He returned to Tokitoki-City from his latest mission, where he could recollect his mind. How did he get into this situation again? Oh yeah, he traveled through time to warn the Z-Warriors from the past from the incoming danger named Jinzoningen. His intention were pure, but the time-travel caused so much chaos in the time-space continuum .

So who is Trunks? He wore a long dark coat, has purple hair and has a sword equipped. Borned as son of the last Saiyan warrior and Saiyan Prince Vegeta and genius Bulma, trained as a warrior and coming from a apocalyptical past, he was a stoic person. Now his current preoccupation was this of a Time Patrol Warrior or "Time Patrol Ranger", like she liked to call her warriors affectionately. Not that he minds it, though, but Time Patrol Ranger sounded like something out from a Sentai Show. He was defacto the leader of the Time Patrol Warrior and after rebuilding the Earth, he was kinda bored. Who knew, that time-travel would cause such a chaos and would put him into this situation?

According to her, there were now 5 different timelines. In one timeline Goku died due a heart virus and Trunks travelled through the past to warn the past about Goku's heart virus and the Jinzoningen and to destroy the Jinzoningen in both timelines. He succeeded, but unfortunately after his triumph against them in his timeline, Trunks got killed by an artificial lifeform named Cell, who stole his time machine. This resulted the Earth of having no warrior to protect it in this timeline.

In another timeline, Trunks came to the past, when Freeza planned to destroy the earth. In this timeline, Trunks and the Z-Warriors fought and destroyed the Jinzoningen. Trunks killed Freeza instead of Goku, which resulted the timelines to split. After the destruction of the Jinzoningen, Trunks returns to his timeline. Goku continued to live in this time and also got a second son named Goten. Vegeta mellowed out in this timeline and his son Trunks became a pride, but brattish little boy in this timeline. But the story of this universe should be told on another occasion.

There was also this timeline, where Cell arrived after stealing the time-machine, just months before Freeza and his father attempted to invade the Earth. In this timeline, Cell absorbed the Jinzoningen #17 and #18 and became the strongest warrior. Goku died due the heart virus, because in this timeline, Trunks never arrived with the time-machine. It is assumed, that Cell is travelling through space, bored and looking for worthy opponents due having the cells of Saiyan warriors such like Goku and Vegeta in him. Well, there was encounter with this weird Magician Babidi, and Cell dared to say, that this encounter was pretty interesting. But we are getting off topic.

Then there was this one special timeline. Why is this timeline special you ask? Well, in this timeline, Cell arrived months prior Freeza's invasion and Trunks also arrived on this timeline. Trunks was also asking himself, how he ended up in this timeline. Not that he was complaining, it's just doesn't add up. She explained, that this was one of the consequences of time-traveling. Well, Trunks just accepted this explanation, it was not like he was that well versed in the theory of time-space continuum. In this timeline, Goku died, but not because of the heart-virus, he died because he sacrificed himself to save the earth from Cell, who got into his Perfect Form by absorbing #17 and #18, from an explosion. Luckily Gohan killed Cell, but Goku stayed dead for another 7 years. But I think the story of this timeline should be all familiar with everyone.

This results us to observing the 5th timeline, the timeline, where our Time Patrol Warrior Trunks is coming from. He remembered, that he got killed and revived in the 4th timeline. After he returned to his own timeline, he killed #17, #18 and Cell effortlessly. He also thought about the Jinzoningen, #17 and #18 especially. They were normal humans, who got kidnapped by Dr. Gero, but somehow it made their mind twisted with evil things. He was grateful, that the Jinzoningen in the 4th timeline were more peaceful, he was pretty interested, what the differences of the Jinzoningen in both timelines were. Well, it was no use to think about it. He was in this whole Time Patrol business, because he broke the rule of time-travel. The rule regarding time-travel? Well, the rule was, that time-travel was forbidden. How was Trunks supposed to know that? It was not like that the gods were writing the rules in some sort of rulebook or that there were even some laws during the apocalyptical state of his Earth. She explained, that creating too many timelines would destroy the universe and Trunks created 4 extra timelines, which was triggered by one innocent time-travel.

"Crap baskets", Trunks muttered. He returned to the mainhall, where he could report his latest mission to her.

A litte girl with red hair, pink skin and pointy ears with earrings saw Trunks and happily greeted: "Heya, Trunks-kun! How was your last assignment? Was it any fun? Was it, was it, was it?"

"There were no problems during my last missions. The bases of the Red Pants army are scouted, but the security in these bases would be probably too much of our current forces to handle. Also it seems, that Mira is assisting various malicious forces on this Earth, one of them being the Red Pants army and he is receiving support not from this universe, possible from the rumored the Khaos Brigade. I think, that I saw Shalba Beelzebub from the DxD universe during one of my espionage missions", Trunks replied.

The girl suddenly took a serious tone. "Well, if this henchman of this guy is assisting various parties there and also get support from the criminals of the Dragon of Dragons realm, I would need some assistance, then. How about I ask Hagoromo-chan for some assistance from his realm? His world seems so interesting. I wanna be a ninja! Ninjas are so cool!" 'Well, this was short', Trunks thought with a sweatdrop. She was being childish again, but he couldn't blame her.

"I would like to leave. Is the meal ready? I'm hungry at the moment and I want to dine", Trunks said.

"Dinner is ready, Trunks-kun. You know where you can find it. I know that stomach of yours, even if you don't want to admit it. You can eat quite a lot. You can't deny your Saiyan appetite. I bet you super hungry and can't wait to eat!", she teased. At the same time Trunks stomach growled loudly and he couldn't hold back a small blush. Despite being a Saiyan and having a big appetite as a result, Trunks prided himself with having excellent table manners, unlike his late sensei Gohan. Well, not that it mattered now.

"I will take my leave now and get to the dining hall, I think my subordinates are eagerly waiting for me to dine with them, Kaioshin-sama", Trunks responded and bowed slightly. After that he left to welcome the other Time Patrol Warrios with his presence.

Yes, the little girl was a Kaioshin, the Kaioshin of Time to be exactly. She has red hair, pink skin and Kaioshin features like pointy ears, earrings and a Kaioshin robe. As a Kaioshin, you can her expect to be older then she looks, millions of years to be exact. She had some powers, yes, but she was not the warrior type. She knew some basic self defence, but for a Kaioshin, she was not on the same scale as other Kaioshins, if you compare their strength. She has unique powers also owned a pet named Tokitoki, who can create time, but only she and Tokitoki knew how this power worked.

"Oh well", she giggled. "I might seek out Hagoromo-chan to assist me in this matter. I hope this grumpy old fart doesn't go all philosophy on me." With this, she planned to visit Ootsutsuki Hagoromo on the next day with Trunks.

Author Note:
This is my first fanfiction and I always wanted to write something about Naruto and DragonBall Online. Well, let's be said that my original idea was much more complicated and I had no plan how to write it. DragonBall Xenoverse came along and I just went with it.
Regarding pairings, NaruHina and SasuSaku for the main cast. ShikaTema and some other minor pairings for the rest.
I also needed an evil party from an universe not being DragonBall and Naruto, originally I wanted Aizen to be the evil dude, but changed it into the Khaos Brigade of the DxD universe. Despite having Highschool DxD in this crossover, I plan to keep the DxD stuff minimal as possible. And no, Naruto and Sasuke won't get a Harem. Also expect cameos from other franchises in this story.
