Prologue
EX: Hello everyone, welcome to a multi-crossover, from my other fanfic, called 'Saiyandimension Neptunia' This is a spin-off of that story, where Zack is trapped in the Highschool DxD dimension as a saiyan. I don't want to spoil anything, so on with the prologue!
NOTE: Keep in mind, if you have read Saiyandimension Neptunia, then this won't happen during the arc portrayed here. It will go normally, like the actual arc in DBS.
NOTE #2: Also my Saiyan OC's name is Zackary Xylax, it might seem like a weird name, and it is considering at first I didn't know that saiyan's names were derived from vegetables when I made his name. It was before the summer of 2017, and I have watched DBZ, DB GT, and all the series, but I was so stupid that I didn't realize that. Please bear with it. A lot of the characters in this story, will not say his full name, but I don't know, it depends on you guys, if his name is odd. Anyways onto the prologue.
3rd Person POV, World of Void, Tournament of Power
Lord Beerus was frustrated, that one of his best fighters and also one of his students, more so Whis' student, was gone. He was nowhere to be found. After he threw a spirit bomb at Jiren, but the Universe 11 fighter, threw it back at him. He disappeared. Lord Beerus clenched his fists, gritting his teeth.
'Is this truly the end of you?" Beerus asked himself, when he shouted "ZACKARY!"
"No no no no! Zackary! You can't be dead!" Purple Sister said, about to cry.
"There there, Nep Jr." Purple Heart said, comforting her.
When all of the sudden, the tournament stage, started to shake, and rumble, but it wasn't just that the whole world of void began to shake.
"What's going on?" Purple Heart asked.
"What is this shaking?" Toppo asked.
"The whole world of void, is being shook by a wild flow of power." Elder Kai said.
"Yes, but what could have done this? No wait, is it!?" Shin asked.
"Of course, it has to be Zack!" IF answered him, with sparkly eyes.
Beerus gained a smile on his face, and his attendant Whis noticed it.
"My lord, do you have anything to say?" Whis asked Beerus, as he closed his eyes, and opened them...
"He's coming!" Beerus said.
A beacon of white light appeared in the crater the spirit bomb made, as Zack rose up, struggling to move at first, but closed his eyes and his posture went back to normal. The light began to suck in rocks, and pebbles alike. It disappeared showing Zack in a new form. He turned towards Jiren and Universe 11, with silver eyes.
But then all of a sudden, Zack vanished, again...
"Wait! What happened to Zack?" IF asked.
"Hmm... Whis." Beerus asked for his attendant.
"Yes my lord?"
"Check for any signs of Zack in our universe." Beerus said, and Whis nodded, checking his scepter for Zack, but he was also nowhere to be found.
"My lord, Zack is nowhere to be found." Whis said.
"What? Are you certain?" Beerus asked.
"Yes my lord, I am positive, but I am sure wherever he is, he's alive." Whis answered.
"HEH! Won't matter now, since one of your best fighters, brother is gone. Your UNIVERSE is history!" Champa said, smirking.
"HEY! It doesn't mean we are out yet, we have Goku and Vegeta! Come on, you two! Win the Tournament!" Beerus said, as Goku stopped fighting Caulifia and Kale. While Vegeta stopped fighting Ribrianne. They both nodded, staying in their base forms as they charged towards their opponents.
Meanwhile, where Zack is...
Zack was now floating around, in his new form. In a never-ending world, that he has never seen before. Although, it had colorful skies then the World of Void, where he was just at. All of a sudden, a large red dragon appeared, in front of him.
"Who has disturbed me?" The dragon asked, his voice echoing across the gap.
The dragon's head faced Zack, with a roar, that released a gale, that did nothing to Zack.
Zack gave his own roar towards the dragon, as the heat and aura around him started to shoot up like a beacon. The heat, knocked the dragon on his back. It started to shake all three worlds, from the dimensional gap.
"Your power... it's shaking the whole universe... What kind of power is this?" The dragon asked...
Heaven...
While Zack was releasing his heat, unconsciously. Heaven was being shaken by the immense power, he was releasing.
"Michael-sama!? W-what is this power?" One of the angels asked him.
"I... do... not know..." Michael told everyone, as all of them were laying on their chests, with the pressure pushing them down.
The pressure was nothing they have ever felt before, not even the dragon god Great Red, could do this.
'This power I have never felt anything like it, and what ever it is... is extremely powerful. Way more than Ophis and Great Red, combined... What is this?' Michael thought, shocked by the current happening in Heaven.
Hell...
The underworld, was also being shaken by the flow of power, that Zack sent, like a tremor.
"Who... has this kind of power?" One of the devils asked.
"I do not know that answer..." The one known as Grayfia said.
"Whatever it is, we must find it..." Sirzechs told everyone, as they were on their knees as well due to the power, the saiyan released.
Back to where Zack is, 3rd Person POV
As Zack, released his power even further, his eyes started to lose some of it's silver color. This new form he gained was about to give out...
That's when he stopped charging his aura, and focused all of his energy into one attack, he cocked his fist back, and went forward, but as soon as that happened, his new form gave out, and he was now back to his base state, conscious, with several bruises on his body. The wave of air, blew against the dragon like nothing.
Zack was laying on the ground barely able to get up, while breathing heavily.
"So that form finally went away huh? And from the looks of it, you look tired. If you don't mind me asking, what was that?"
"I...do not know much about it, myself." Zack was able to speak, again.
"So you don't know what that was? Huh interesting, what is your name, young one?" The dragon asked.
"My name is... Zackary... Zackary Xylax... and yours?"
"Mine is Great Red, or I am known as the Apocalypse Dragon. But enough about that, I can sense that you are much stronger than you look, since you knocked me over on my back."
"Wait... I did?" Zack asked, surprised.
"I am assuming that you didn't know that you did that." Great Red said, curious.
"Yeah, I was unconscious, but I didn't know I was actually awake." Zack said, sitting up, as he was resting his body.
"Wait you weren't awake? It looked like you were, since you had silver eyes."
"Huh, still I am pretty sure I was unconscious." Zack told the dragon.
"Anyways Big Red, will it be okay for me to rest here for a couple hours? I mean I know I am invading your space, but it won't be for that long, promise." Zack asked.
"Sure Zackary, but if you don't mind me asking, why?"
"Well cause right now, I am exhausted from using that form, what I am saying is this, my stamina has run out, and I need some time to rest." The saiyan said.
"So that's why, it gave out. Hmm alright, but just for a couple hours. And don't stare at me!" Great Red said.
"Okay! Jeez... I wasn't going to do that anyways." Zack said, before putting his two index fingers on his forehead, trying to find Goku's ki signature, but nothing. He couldn't find it.
"What were you doing?" Great Red asked.
"Oh! I was using a skill that someone taught to me a long time ago, called Instant Transmission." Zack said, making the dragon curious.
"What does it do?"
"Well as my mentor told me, it gives you the ability to lock on to an energy signature and it takes you there. It can go over long distances, like I am right here, and I could get to Mars and back in a couple seconds." Zack explained.
"That is incredibly useful! You are full of surprises! Anyways you stopped using it, why?"
"I couldn't teleport back to the person I know, and he is one of my best friends. His name is Son Goku, he taught me most of the moves I know right now, and he was more nicer, and less strict than the prince of our race was." Zack stopped, realizing the dragon looked like he was getting tired.
"Oh I apologize for rambling. It's just that my story is long, and you might not want to hear it." Zack said.
"Zackary, that's not it. It's just that I haven't slept for a while."
"Okay, but would you still like to hear my story? I mean it might interest you, and it will probably be done before I am rested."
"Okay sure, besides it will be something for you to do anyways. I mean there is nothing in here, to do except sit around or nap."
"Alright! So it all started, with..." Zack told the story of how he came to the Hyperdimension, and helped his friend defend their nations, from several enemies. Including Frieza, Broly and some new enemies that he faced. As well as the last bit, where he was taken away from the Tournament of Power.
"And that's about it." Zack finished.
"Wow that did keep me awake, and it's interesting to see someone such as yourself, have power like that. Even more than a god? How is that possible?"
"Well probably not more than a god of destruction in mine, but probably more than an actual god in your universe. And since, all of my stamina is back..." Zack said, before standing up in the dimensional gap. He clenched his fists, screaming to turn to his full power.
A blue light appeared, and faded, as blue ice cracked to reveal Zack in his blue form.
"Super saiyan blue... this is the form I gained, training with Whis, Lord Beerus' trainer."
"Amazing... so what will you do now?" Zack turned back to his base state, pondering for a couple seconds.
"I...I don't know. I know that I can't go home now, so that is out of the picture." Zack said, still thinking.
"But the question is, where could I go? And where would I live?" Zack asked, when he got an idea.
"I got an idea, Great Red! I need you to do me a favor." Zack said, with a smirk on his face.
"Sure, why not? Besides not many people have been able to knock me over like you have. What is it?"
"I need you to transport me somewhere in this universe, please just this once."
Great Red opened up a portal to a supposed dimension, that Zack didn't recognize at all.
"All right, but before you go, here take this. It will help you fight. Use it well."
Great Red, had his claw out to reveal a sword, with a sheathe that said 'Destruction' in Japanese.
"I have never had any use for it, I called it Apocalypse, the sword that brings destruction. So bye, but if ever want to train with me, I could gladly help with that." Great Red, told me, before I flew into the portal, and started to plummet down towards the ground.
"Well that's that! Here WE GOO!" Zack said, before going faster.
EX: Well, I never thought I would come this far as an author, what I mean by that, is making a Highschool DxD crossover fanfic! Keep in mind, I will try to make these chapters longer, but Prologues to me are always short, sweet and to the point. I always have a tendency to make smaller chapters, so please bear with that. Now onto questions you might be having, and explanations!
A/N 1: Okay so this OC you have Zackary, attained Ultra Instinct, and for some reason Goku & Vegeta didn't gain it yet. Why? Well Zack is my main OP Saiyan OC, otherwise he is the protagonist of every story I make with him in it. If that's not a good enough reason for you, then I will say if it doesn't focus on Zack, then he won't be the main protagonist of the story.
A/N 2: This is a spin-off from Saiyandimension Neptunia your other story, why did you do this? Because why not? I mean I never did any that actually did a great job, and one of them is being remade still. But this is one of the first spin-offs I actually plan to make fully.
A/N 3: So Zack has attained Ultra Instinct, and the form was still there when he got to the dimensional gap, why? Because the form didn't reach it's limit yet, and I thought since I have seen the episodes where Goku has earned the form and also where he has lost the form, he becomes exhausted.
A/N 4: So Great Red had a sword to give to Zack? How and why? Well for how, he made it himself, and the reason why, is cause Zack, has way more power in his UI state than Great Red does, and was able to tip him over, which I guess is a weird way to put it.
Power Levels:
Zack(Base Form): 600,000,000
Zack(SSJB): 120,000,000,000,000,000 (I know it kinda seems like a lot, but I am trying to look it up to make it as accurate as possible)
Great Red: 100,000,000,000,000,000 (I don't want a god dragon's PL to be too low, and also I didn't want Great Red to be too OP)
Zack(UI): 240,000,000,000,000,000
Well I tried to keep them as accurate as possible minus Great Red's PL, that was to balance the powers out. Although maybe I shouldn't do PL at all. Cause this does seem ridiculous doesn't it?
Now the next Chapter preview!
