A/N: Hey everyone! This is the start of a brand new story. Actually, this is the first crossover between the Dragon Ball and the Toaru franchises. On another note, today marks the end of Toaru Majutsu no Index III as well as the end of the Old Testament Saga in the series with the conclusion of the World War III arc. As a reminder, Toaru Kagaku no Accelerator is coming this July and Toaru Kagaku no Railgun 3 later this fall or winter (possibly). In other news, I'm temporary taking a break from TRON: Awakening and focusing on this original story, so expect the first chapter of Xeno Warrior coming soon. See ya next time, Space Cowboys!
Prologue
Age 855
Conton City
Universe 7
Fires are raging on the streets of Conton City, home to the Time Patrol. Most of the Patrollers have been slaughtered in a final battle against a dangerous threat to not only all of space-time, but to all of mortal kind. The only ones still standing is a severely injured Future Trunks (DBS) and another hybrid Saiyan, who is almost out of power. The latter has short spiky jet black hair that closely resembles Future Gohan's, black eyes, and wears dark blue and green Battle Armor with dark blue combat pants, long red armbands as well as matching leg warmers (Bardock's Armor from the Father of Goku Special; given to the Future Warrior as a gift). His skin tone is peach colored and surprisingly has no scars on his face. But the most noticeable thing is the red headband that once belonged to a certain badass Saiyan with a scar on his left cheek. Although he resembles to be an 18-year-old, the hybrid Saiyan is technically 14 since he trained in a dimensional space similar to the Hyperbolic Time Chamber for 2 years (inside the chamber, which is 2 days in the real world).
The enemy that they are facing has green skin, gray eyes, and white hair that closely resembles a Super Saiyan but with a long protruding bang over the right side of his face. He wears two green Potara earrings on both of his pointy ears and Supreme Kai clothing but dark grey, including a long-sleeved black undershirt and red sash around his waist. The most noticeable feature is a Time Ring on his right index finger. However, his attire is battle-damaged and had cybernetic implants on his right arm and an eye patch to contain his unstable Half-Corrupted form of his semi-immortal body. His name is Fused Zamasu, the Potara fusion between Goku Black and the immortal Future Zamasu.
Zamasu looks down on the Future Warrior's, who barely could get up and continue the fight against the rogue Kaioshin. "I know what it's like to lose, Saiyan. To feel so desperately that you're right, yet to fail nonetheless. It's frightening, turns the legs to jelly." He shares the times that he lost against his enemies before grabbing the boy by the hair and drags him across the dirt towards the injured Trunks. "I ask you to what end? Dread it. Run from it. Destiny arrives all the same. And now it's here. Or should I say, I am."
The Future Warrior coughs up some blood and rolls his eyes at Zamasu's annoying monologuing. "You really… *coughs* talk too much."
"Honestly, Jason, I agree." The 30-year-old Trunks admits. "Though for him, he only cares about himself and his stupid ideals of justice."
Zamasu then releases his hold on Jason and looks at both of them. "You are all out of options, Saiyans. Your Time Patrollers are dead, and soon the Supreme Kai of Time will die."
Jason then laughs it off, confusing and angering the rogue Kaioshin who responds to it by slamming the Future Warrior's face into the ground. "How dare you laugh at a god, you damn Mortal!"
"What? Did I hurt your feelings?" He mocks him as he slowly gets up and moves away from Zamasu. "All insults aside, you kill her, you end all of space-time and everyone that exists, including yourself!"
"How right you are, Saiyan! Which is why I will make sure she hands over her title to me and once I've dealt with you and Trunks here, I will then use the Time Nest to rewrite history in my own making, ridding the Multiverse of all Mortals and Gods, thus finally creating a perfect utopia that'll never again be stained!"
"How hypocritical, Zamasu. At least learn to take notes from the likes of Thanos for once about the natural balance." Jason roasts before grinning cockily. "Remind me, who was it again that got his ass kicked and let his own arrogance get the better of himself? Let me guess, it wasn't me."
Zamasu has enough of his insults. "ENOUGH!" The rogue Kaioshin then levitates up in the air and prepares to launch his most devastating attack in the form of a sun-like giant Ki blast. "You think you can tell me, a god, what to do?! It's the end for both you and Trunks!"
"Way to piss him off, Jason!" Trunks yells in sarcasm. "Now the multiverse and reality is screwed!"
"Relax, Trunks." He smirks without a hint of panic within him. "It's all under control."
"Relax?!" Trunks angrily yells. "Zamasu's about to kill us both and we don't have any power left!"
Ignoring him, Jason counts down in his head. "Chronoa should've used the Namekian Dragon Balls by now. And it should happen right abouuuuuuutttttt…. now."
And right on cue, both Jason's and Trunks's strength returns to them.
"My strength! I can feel it coming back to me!" Trunks says with joy.
"Don't thank me. Thank Chronoa."
"Jason, Trunks! Can you both hear me?" The telepathic voice of Chronoa, otherwise known as the Supreme Kai of Time, asks.
"Supreme Kai of Time!" Trunks exclaims.
"About Goddamn time!" Jason says in irritation. "What the hell took you so long?"
"Hey, it's not easy to collect all of the Namekian Dragon Balls on Namek you know! Show some respect!" The Supreme Kai of Time's voice yells angrily at him.
Jason sweatdrops at her short temper, scared shit of his boss. "Okay, okay. Sorry I asked. Thanks for bringing most of our strength back, by the way."
"No problem! I've prepared another wish for Porunga to grant us!"
Before Jason could ask on what she's talking about, Zamasu interrupts them. "So the Supreme Kai of Time restored your strength? No matter. This is your end! Holy Wrath!"
He then throws his Holy Wrath at his opponents as it comes crashing down on them. However, Jason powers up to Super Saiyan Blue and Trunks to Super Saiyan Rage. The two then nod at each other and then charges through Zamasu's attack, destroying it.
"I-Impossible!" shocks the evil Kaioshin. Zamasu then tries to deliver a shockwave punch at the two fighters but Jason and Trunks vanish, and the former reappears from above and sledgehammers him with his fists, causing the latter to impact on the ground. As the dust clears, Zamasu recovers quickly but Trunks was already in front of him and delivers a punch so hard that the evil Kaioshin crashes through the buildings sustaining heavy injuries, but instantly heals himself all thanks for being half immortal.
Jason and Trunks then flies down toward their opponent and corners him. "Give it up Zamasu! I won't say it again!"
Zamasu then powers up angrily with a yell, creating a rainbowed white aura around him. "Damn Mortals!"
Suddenly, a bright light covers Zamasu and the two hybrids cover their eyes from the blinding light. When the light has died down, standing in the Fused Zamasu's place is two different people. One has a dark grey tunic with a long-sleeved black undershirt, red sash around his waist, and white Supreme Kai boots. His face and spikey palm tree-like hair is that of Son Goku's but with a skinny body and a Time Ring in his right index finger, including a single green Potara earring on his left ear. This is Goku Black, the Zamasu from alternate present day timeline who stole Goku's body and started the infamous Project Zero Mortals. As for the other, he looks like the Fused counterpart but with a different Supreme Kai color scheme, a green Potara earring on his right ear and a white mohawk with its bang down on the right side of his face. Enter Future Zamasu, Black's counterpart from Trunks's already erased future timeline.
"What just happened?! The Potara fusion should be permanent!" Black says in complete shock and confusion.
"Isn't it obvious? It would seem the Supreme Kai of Time has used the Dragon Balls to separate us. And we can't fuse again for another hour it seems." Future Zamasu quickly deduces.
Black becomes angry at this but calms down and smirks. "Hmph. It matters not, my dear counterpart. We still have enough power left to defeat them."
"Agreed." His future counterpart nods.
"So, Trunks, which one do you want to go up against?" Jason asks with a smirk while he and his partner face against the two versions of the same fighter.
"Black no doubt. I've got a score to settle with him for destroying my old reality." Trunks answers while gritting his teeth in anger at the false Saiyan who killed his mother. "You take Zamasu, Jason."
"Heh, figures." Jason shrugs before frowning in annoyance. "There's still one problem. It's that damn immortality of his. Good thing I had time to master a technique I've been practicing before the mop up we had on Prison Planet and the Core Area Warriors not long after."
"Technique?"
"Yeah. I've been saving it as a last resort against immortal beings. It's the technique that Lord Beerus used to destroy Zamasu from the present day timeline."
Trunks eyes widen. "Did you say Lord Beerus?!"
Jason nods. "That's right. And if we tried to destroy his immortal body the regular way like you did before, he'll end up becoming the multiverse itself again and will try to infect other realities as well. Keep Black off my back till I've eliminated Zamasu for good this time."
"Right. Good luck." Trunks nods before the two get into their fighting stances and charge at their chosen opponents.
Jason and the Future Zamasu traded blows with their kicks and punches, parrying blow by blow. Future Zamasu launches Ki blasts at him as Jason then evades them with acrobatics before flying upwards and the former follows him. Zamasu then tries to finish him off with his God Split Cut energy blade (a field of purple energy around his right hand) from behind, but Jason saw this coming and quickly catches it with one hand. Jason then fires a yellow Ki blast at him and moves back away from the Future Zamasu.
"You honestly think you can defeat me?" He chuckles evilly. "You forget that I'm immortal."
"I know. Which is why I have one move that you'll never survive out of." Jason cryptically smirks.
"Oh really? I can't wait to see what kind of plan you have against an immortal god like myself." He taunts at the Future Warrior.
"You will, alright." Jason promises as he launches a Super Kamehameha at him. Unfortunately, the super attack did no damage to the immortal Zamasu as his body regenerates.
"That's your trump card?" He laughs maniacally. "How disappointing. It's over, Saiyan."
But when the dust clears from the attack, Jason was no longer at the position he fired his Kamehameha at.
"Where did you go?" Zamasu asks out loud to himself as he looks around.
"Right behind you." The Future Warrior answers from behind (via Instant Transmission)
Zamasu quickly spuns around to cut Jason down with his energy blade, but he wasn't fast enough, and the Future Warrior catches and dissipates it. Zamasu tries to escape his strong grip on his hand but Jason held tight on it.
"Lights out, fucker." Jason says before putting the palm of his right hand in front of Zamasu's face and use the technique of the Hakaioshins (Gods of Destruction (G.O.D.S.); Destroyer Gods; Destroyers). "Hakai!"
Just then the evil Kaioshin screams in agony as his immortal body and spirit within him glows purple and is completely disintegrated in the process, and his screaming is silenced. At long last, the immortal Future Zamasu is destroyed… again. For real this time. (No, not kill. As in completely erased from existence)
"Annnnnnd problem solved." He comments before wincing in pain and reverting back to his base form. Jason chuckles to himself. "Gaahhhhh, no wonder the Hakai puts a huge toll on my body. Even with the combined efforts of stamina draining Super Saiyan Blue. Only reason why I'm not a Destroyer God and can't use this technique without killing myself."
Taking out a Sensu Bean, he chews it down, restoring his strength again. Just then, he senses Black's Ki and he's already coming to him.
Meanwhile, Trunks is doing what he can to hold off Black but counters him with his Black Power Ball, sending the former flying through 5 buildings across the city. As he prepares to finish him off, Black could no longer sense his future counterpart's Ki and the only one remaining in the opposite direction is Jason himself.
"Zamasu's Ki… it just vanished. *growls in anger* No doubt he must've got sealed away again with that primitive jar of theirs." Black thinks as he uses his middle and index fingers to perform Instant Transmission, teleporting to Jason's Ki and appears right before the Future Warrior.
"So you sealed away my comrade, Saiyan? Your victory will short lived once I've ended you and release him."
However, Jason still has that smug grin on his face. "Really? Unfortunately, I destroyed him, so now we can have no cheaters involved."
"You what?! I-Impossible! You're not even a Destroyer! No way you could've survived using that technique of theirs, let alone recover from a huge toll!"
"I learned it just by watching Beerus used it." He shrugs. "Honestly, I didn't think it would work, but at least I didn't die from its after effects. Plus, that was the first time I've used it while in my Blue form."
"Why you!" Black growls in rage. "HAAAAAAAAAAAAAAAAAAAAA!" With a godly roar, he transforms into his most powerful form. It resembles that of Super Saiyan and Super Saiyan Blue, but with his spiked up 'pineapple' hair being pastel pink and his eyes light grey like that of Future Zamasu. His divine aura has a very dark shade of red on the outside while the inside of his aura is purplish pink. This is the opposite of Blue: Super Saiyan Rosé.
Jason could only grin at this. "Heh. Looks like I need to step up my game for a change."
The Future Warrior then transforms into SSB again and powers up. Jason is now using his Blue form with the combined might of the Kaio-ken: SSB Kaio-ken! The outer Kaio-ken aura manifests as violently fluctuating and jagged while the Super Saiyan Blue aura maintains a gentle, flame-like contour. His skin is slightly illuminated into a pink color. Cranking it up, Jason gives out his own godly roar and powers up the Kaio-ken Blue technique to 20x its power, amplifying his speed, strength, and other senses, and his aura illuminating his skin tone to darker shades of red.
"KAIO-KEN TIMES TWENTY!" Jason roars before proceeding to charge towards Black. The false Saiyan easily saw this coming and guts him in the abdomen. However, this didn't flinch the Future Warrior, and he places his hand with his index and middle fingers out near Black's chest then makes a fist to deliver a hard punch to his opponent's gut, blasting him with a powerful shock-wave (Super God Shock Flash).
Black coughs out some of his own blood and gags from Jason's attack. "Gaaahhhh!" Wiping some of the blood off of his mouth, he tries to punch him but Jason blocks this, forcing Black to deliver punches and kicks, in which Jason counters them with parries before proceeding to right hook him in the face. The Future Warrior then grabs Black's left leg and with a mighty war cry he throws him down towards a tall building, which collapses from Black's collision. Jason then launches a volley of energy blasts and then gets into a stance by cupping his hands to his right side, generating a blue ki in a single point.
"KAAAAAAA-MEEEEEEEEEEEEEEEEEE-HAAAAAAAAAAAA-MEEEEEEEEEEEEEE-HAAAAAAAAAAAAAAAA!" The Future Warrior chants before thrusting forward to launch a powerful beam of energy (20x God Kamehameha) to where Black crashed on impact, creating a gigantic explosion that could dwarf the size of a min-nuke. When the dust clears, Black creates an explosive wave to shake off the debris on top of him, and he is left unscathed with only a few bruises and a broken jaw. This only made Black receive a ridiculously huge of amount of Zenkais, making him get stronger in battle each time his injuries are severe.
"Damn! That was supposed to be my most powerful attack and yet he tanks it like Broly (DBS) did! Why won't he just fucking die already?!" He rants angrily that his attack is shrugged off like nothing.
Black simply laughs sadistically so loud it still send chills down Jason's spine. "I have to admit, that tasted more like a dessert than an appetizer. Although you and I use to already be on equal footing, I've already reached even further heights of power!"
"Oh space Christ, he's getting stronger." Jason sarcastically says with an eyeroll.
Black powers up even further and proceeds to shock Jason even more when he utilize the Kaio-ken to his Rosé form with the technique's crimson aura being dark on the outside and his divine aura on the inside.
"N-No way! He figured out how to use the Kaio-ken?!" Jason says in awe and terror.
"What do you think? This new form deserves a name of course, so…" Black mockingly ask for his opinion. "Ah, yes. I shall now call this one 'Super Saiyan Rosé Kaio-ken. Genius isn't it?"
Jason begins to sweat at this as he realizes that he's reached his limit. "That form looks impressive, I'll admit, but this is bad! If Black starts to use this new form more often than his Rosé form, he might surpass the twenty times limit and continue to get stronger! There's no way to defeat him, and even if I use the Hakai on him I'm not sure if it'll work on him, given to how ridiculous he gains more Zenkai boosts! Not to mention, I won't have time to use it on him! Trunks is down and Black's too much for me alone!"
Black chuckles at how scared Jason is feeling. "What's wrong, Mortal? Do give up, now that my power level is higher than yours?"
As Jason was about to give up, one more idea pop into his head. "That's it! If I can't end Black for good, then there's one other option left!"
"Chronoa! You still there?!" Jason telepathically contacts the Supreme Kai of Time.
"Loud and clear, Jason! How goes the fight over there?"
"Not good. I manage to destroy Zamasu but Black is the only one remaining."
"Hold on, destroy?! But Zamasu's immortal!"
"I'll explain later! Right now, I'm almost out of options!" He pauses for a moment before speaking again. "Chronoa, I'm gonna have to use the new weapon I've been working on."
"W-Wha?! No way! If you do that, you'll die!"
"Everyone else will die if I don't do it! It's a risk I gotta take! You have to trust me on this one!"
Jason then takes out a grenade of some kind and yells at his opponent. "Black! This is for all the innocent blood you spilled throughout the multiverse!" He then clicks on the detonation button and throws it down to the surface, which nothing happens at first.
Black blinks in confusion and then laughs again. "HAHAHAHAHAHAHAHAHA! Pathetic Mortal! That's it?"
And suddenly, the grenade explodes creating a large black hole and begins to suck in both Jason and Black.
"NO! NOOOOOO! IMPOSSIBLE! I AM A GOD! I WILL NOT BE BEST BY SOME LOWELY-!" Black rants in anger as he struggles to get away from the black hole before Jason punches Black's face so hard that the false Saiyan's neck breaks.
"SHUT UP! YOU LOST THE RIGHT TO BE A GOD WHEN YOU MURDERED YOUR OWN MASTER AND EVERYONE THAT HAS NOTHING TO DO WITH THIS!"
"HOW DARE YOU! I AM TRUE JUSTICE! A SWORD AGAINST EVIL THAT YOU MORTALS SPREAD LIKE AN ENDLESS DISEASE!" Black stubbornly disbelieves to the end with no regrets of his actions.
"YOU KNOW WHAT HAPPENS WHEN PEOPLE LIKE YOU DECIDE TO PLAY GOD AND COMMIT GENOCIDE?! THEY DIE! SO TO HELL WITH YOUR JUSTICE, BASTARD! YOU DON'T DESERVE IT!" Jason declares before grabbing Black's broken neck and drags him into the black hole.
Inside there is nothing. Sound and matter doesn't exist. Only nothingness. Their voices can't be heard as Jason drags the false Saiyan deeper in the black hole. He then throws Black across the emptiness and Jason reverts from his Kaio-ken Blue form to SSB at Full Power and flies toward the exit before the black hole could close and tear him apart. And in a nick of time, the Future Warrior makes it out alive, crashing onto the ground and reverting back into base form, exhausted from the final battle. Looking back, the black hole implodes and vanishes without a trace. Jason – whose armor is damage in the fight – pants heavily from using up all of his ki before slumber overtakes him.
At last, the threat of Goku Black and Zamasu have been eliminated, and reality is saved once more…
(Time Skip)
3 Weeks Later…
Jason slowly opens his eyes as he recognizes that he's in a hospital room. Just then, Chronoa and Trunks enter the room and the former slaps him in the face.
"Ow! What the hell was that for?!"
"That's for pulling off something so suicidal. And yet, my best Time Patroller almost died! Not to mention that you learned the Hakai that only Destroyers can use."
"Sheesh, I'm sorry." Jason apologizes to his boss as he rubs his sore cheek from the slap. "There was no other way to stop Black and Zamasu."
"Hmph. You can be really paranoid, you know that?" She crosses her arms and looks away.
"But other than that, it's good to see that you're still alive, Jason." The older hybrid smiles.
"Thanks."
The three didn't say a word for a few minutes until Jason breaks the silence. "How long was I out?"
"Three weeks at most." Chronoa answers. "After you were out, I used the third wish from Porunga to bring back most of the Patrollers that were killed by Zamasu (Fused) and restore Conton City back to normal."
"What do you mean most?" He asks nervously.
She sighs sadly. "We couldn't bring back Trunks (Xeno) and Ace. Their souls were destroyed."
Future Trunks (DBS) and Jason knows what she was talking about. "So other me's gone, huh? I'm sorry that you lost your best assistant, Supreme Kai of Time." He then turns his gaze towards Jason. "So… it's finally over? Are they gone?"
The Future Warrior nods his head. "Yeah. Both of them are dust in the wind. We won't have to worry about them anymore." He pauses for a moment before speaking again. "So what now? The Time Patrol needs to go on and we need someone who can lead them on the field."
Chronoa thinks for a moment. He's got a point. With her Trunks and Jason's predecessor gone from existence, she needs a new field leader on certain missions against time breaking criminals. "What about Beat and Note?"
"Huh? You mean that young couple?"
"Well, they have been at it longer with Ace before you showed up. Plus, they would do an amazing job together as co-field leaders."
To be honest, she's not wrong there. Plus, they have been at it longer, even though he's the better fighter than the rest of the Patrollers. "Then it's settled. Tomorrow, they get their promotion."
"Great! Then this calls for another celebration!" She declares.
Jason pales in horror, confusing Trunks.
"Uh, what's she talking about?" He whispers to the younger hybrid.
"Her cooking. It's really disgusting."
"How bad is it?"
"Your counterpart learned that the hard way since they first met and trust me, it's probably better if you don't experience it." He explains before focusing on the petite Lord of Time. "Why don't I cook instead? Plus, I'm a badass at it and you clearly suck at it."
"I do not!" She childishly whines.
"Do too."
"Do not!"
"Do too."
"Do not!"
Clearly, they argued for the next 10 minutes before they checked Jason out of Conton General and the three ate dinner at his small apartment, thanks to his cooking skills no doubt. The three then discuss about the future while they eat.
8:30 PM
"So I guess you are going back to your timeline, Trunks?" Chronoa asks while eating a bowl of ramen.
"Yeah. With what's happened in this reality, I'm sure you all got it under control."
"Actually, there's one more favor I want to ask you." Jacen says before showing a Time Ring to the both of them.
"Black's Time Ring! How?"
"I took it off of his index finger while I was dragging him deeper inside the black hole."
"That's smart, Jason. Nice Job. I'll see to it that it gets locked away."
"No." He shakes his head in disagreement. "That's not it."
"What then?" Trunks asks.
"Trunks, this ring can't fall into the wrong hands. And this could possibly bring back both Black and the Future Zamasu. These recent events must not happen again. Will you go to the present and ask Beerus to destroy it on your way to your reality? It's so that their other incarnations don't get created."
Trunks takes the ring in his hand and nods with determination. "You have my word. I'll make sure Lord Beerus takes care of it. I promise."
"Thank you, Trunks. I owe you one."
"And what about you, Jason?" The Supreme Kai of Time then asks her best Patroller.
Jason was a bit taken back with this question about him. He hadn't thought of it that far. Though come to think of it, he feels homesick and really misses the world he was born on, but it's located outside of the Multiverse, considering that it's not in Zeno's jurisdiction as that universe is independent and not even worth the Omni-Kings' time.
Sighing, he answers his superior and friend's question. "Chronoa, I wanted to thank you for making me a part of the Time Patrol and for giving me the strength and courage to keep on fighting the good fight. But… this is maybe the last time you guys might see me."
"What?! You can't be serious!"
"Hear me out. For three years I've been the multiverse's most powerful Time Patroller and now that I see no reason to continue being an elite Patroller like myself, I'm taking early retirement from fighting as a warrior."
"B-But you're one of my best students at the Patroller's academy! Why would you want to give up being a fighter if you're planning on going home?!"
"Because I miss my home!" He snaps, shocking Trunks and Chronoa at his little outburst. He then calms down and explains further. "All I ever wanted was a normal life. I didn't become a warrior and embrace my Saiyan heritage because I want to fight for the thrill of it nor for the glory. It's because I didn't want to in the first place. I've been on my own since I was five. I didn't really fit in anywhere, even in the Time Patrol. My faith's in people, I guess. Individuals. And I'm happy to say that, for the most part… they haven't let me down. Which is why I can't let them down either. Locks can be replaced, but maybe they shouldn't. I know you don't want to see me to go, Chronoa. I guess I thought by staying here with you and the Time Patrol… I was sparing you… but I can see now that was really sparing myself. And I'm sorry. Hopefully one day you can understand. I wish I could stay with you guys. I really do. But my place is my own universe. My Earth. And I know that you're going to miss me as much as I'll miss you."
This brought tears to the Supreme Kai of Time knowing that it's his choice to either stay or go home. "I understand. I understand that you miss your old home entirely that you formed a strong connection there."
Jason smiles that she understands and cares for him like a true friend would. "So no matter what, I promise you… if you need help… if you need me… I'll be there."
She then wipes her tears away and returns his smile with her own. In the end, she and her Time Patrol are going to miss him, but luckily Jason will one day come back to help them if they need it. That's a promise he'll forever keep…
