A/n: This is gonna be brutal, so get ready. I don't own Invincible or Dragon Ball Z, now let's begin.

Unknown Time

The air of planet Cereal was filled with nothing but tension as Anissa gripped Y/n's hand tightly as the two floated down towards the now blown away city.

Anissa: This could've gone better, I honestly wished you'd listened.

Her grip increased causing Y/n's right hand to crack and break making him release a yell that was stopped when she planted her foot in his face sending the Saiyan flying back.

Y/n had crashed through the ground causing a trail of destroyed and morphed rocks to form around him before ultimately coming to stop.

His vision blurred as he looked at his hand only to see bone sticking out of different parts of it along with the blood soaked bandana that rested in it.

Anissa: The empire, won't tolerate this. These life forms are lower than insects, yet you risk your existence for them.

Blood escaped Y/n's mouth as he coughed some out while Anissa approached with an unamused look, the scouter she had on scanned Y/n who struggled to get back up.

Anissa: Your mind is as useful as your might, that machine you made in your cell along with this device proves it.

Y/n: So let m-me be, you have more than I coul-

Anissa stopped him by gripping Y/n's throat making him quickly grab ahold of her wrist with his non broken hand leaving his onxy coated irises to pierce through the Viltrumite.

Anissa: You know why, the empire demands your strengt-

A Ki blast flew through the air and seared the back of Anissa who turned around with a mute expression only to gain a shocked one as a barrage of blasts impacted against her. This sent her flying back as two Cerealian's flew in towards Y/n.

They quickly grabbed the hazy and battered Saiyan who looked around confused as the green haired warriors flew Y/n out of the area.

Cerealian 1: We gotta get em to the nearest ship!

Cerealian 2: Hey! Hold on for just a bit longer Saiyan!

Y/n: Wh-What the he-hell are you doing?

An explosion was trigged behind them along with a boom as body parts along with buckets of blood and dust flew over the three as Y/n saw more Cerealian's charge at the combative Viltrumite.

A stinging pain rung throughout his body causing the end corners of Y/n's vision to become blurry as blood began to build up in his mouth making the Saiyan spit out a splotch of blood.

Cerealian 1: We can't take on the Empire but you have a shot!

Cerealian 2: We'll get you off planet so that you can see another day! So just hang on!

Y/n: D-Damn idiots ugh.

The previous wounds inflicted onto the low class warriors body finally caught up to him causing Y/n to finally give out as one final explosion rung behind him before completely blacking out.

Location: Sombrero Galaxy
Planet: Vegeta
Afternoon

10 Years Ago

The red colored planet of Vegeta was seen having multiple pods shooting out of it's orbit as multiple war ships floated out of it's atmosphere. As it did so below outside the confines of the city which held the Saiyan elite who lived in the central hub of the planet.

Each of the tall white buildings had Saiyan's flying around each one along with some standing on the balconies of the alien like structures chattering amongst each other, some racing towards whatever goal they had set along with some of the more brutish types battling and training within the heart of Vegeta.

Inside one of the dome like building more meeker looking Saiyan's were seen walking about brandishing white coats, armor that looked heavier than themselves and were surrounded by various pieces of sensitive equipment.

One of the spikey haired Saiyan's with dark blue and green battle armor along with putting on his dark blue combat pants as he strapped on red leg warmers, it was covered mostly by the lab coat he wore as a pair of goggles were on hiding his eyes that were glued onto a glass case.

Within it was a ball of white energy that pulsated within the container as the scientist stuck his gloved hand towards it, when it got close a bolt of lightning struck out towards the hand causing the hand to open up and allow the lightning to dance around the palm.

???: How're the tests going Y/n?

A grunt left the Saiyan's mouth as he retracted his hand back and sealed the container as Y/n removed the scorched glove revealing his smoking hand that was twitching slightly. He then moved his goggles up to rest on his forehead revealing his scowling face that turned to the shorter and more meek looking Saiyan who addressed him.

Y/n: Better then before but the damn power ball won't stabilize properly and produce enough blutz waves. You can look over my notes later Ruta.

The long spikey haired short stack was confused at the implication as Y/n walked out of the lab and into the hallway as Ruta followed quickly behind nearly bumping into another Saiyan who was walking the opposite way.

Ruta: What're you talking about Y/n, this research is beyond crucial!

Y/n: Ya think I don't know that?

Ruta: It just seems like you're undermining your research and the progression of Vegeta!

Y/n stopped and looked over at the Saiyan who bumped into his back as he was now looking down at Ruta with an eyebrow raised communicating to the fellow scientist his inquire.

Ruta: Th-The King Y/n.

Y/n: Mmm then that answers it alone, that moron couldn't find his way around a scouter let alone something this complex. *He said before continuing to walk forward*

Ruta: You shouldn't say such things about King Vegeta out in the open.

Y/n: Why not? He's gonna somehow take credit for this and I already said I'd finalize anything that would need me, afterwards it'd be up to the rest of you.

Ruta: Right but your first mission isn't unti-

Y/n: I accepted another one and I set off for it tomorrow.

Ruta's face paled at the revelation as Y/n stopped before taking off the coat he wore along with his goggles handing them to his colleague along with a card that had his name on it.

Ruta: T-There isn't anyway I could convince you to stay huh?

Y/n: No, not this time. Besides, I'm not gonna anyone's tool.

The Saiyan then walked out the building leaving Ruta to look on before letting out a disappointed sigh as the power ball Y/n was tampering with convulsed with energy within it's container.

It then glowed even more as the ball of energy soon turned into a shattered moon that highlighted the darkened sky illuminated by violet leaving the unknown planet in a state of peaceful rest only for it to be interrupted by a horde of reptilian like creatures flying through some clouds while being highlighted by the large celestial body in the sky.

As they did so it panned down below towards a caves that had a flickering light within it. The crackles of a fire were heard from within the illuminated cave as Y/n was seen propped up against the wall.

His breathes were shallow as a pained expression etched itself onto his face which was soon followed with mutters escaping his barely open mouth, it died down when he felt a presence in front of him causing the survival driven Saiyan to jolt up awake.

He raised his right hand filling it with sporadic blue energy arched over his head only to be met with ki aimed directly towards his head making the Saiyan hesitated for just a split second causing the searing pain ringing through his body to halt Y/n and violently cough out blood onto the ground.

The attack aimed at him was hesitantly retracked back allowing the heaving Saiyan to see the green haired women who was seconds away from putting a hole in his already hurting head now standing with her arms crossed.

???: Didn't expect you to wake up so soon.

Y/n: Wh-Where the he-hell am I? *He asked trying to stand up*

???: Whoa, hey you shouldn't be moving!

Y/n winced as blood spurted out of his open wounds the moment he stood up causing him to fall onto the ground paralyzed and twitching leaving the Cerealian woman to grab Y/n and place him back on the wall while placing the back of her hand on his forehead.

After a quick feel she pulled back and grabbed a rag that was resting halfway in a bucket of water taking it out while wringing it before placing it on the half awake Saiyan's head.

???: Just rest for now and we're not on Cereal. 

Y/n: Bu-But I remember I was just there, yo-you're people they were-

???: Slaughtered.

Y/n went a bit wide eyed as she gained a dismissive look while moving over to the opposite side of the small cave they were in leading her to sigh and look at Y/n who was still processing what she said.

???: The Viltrumite's finished what they started, the planet was already growing unstable due to the moon being shoved into the planet. Then after you destroyed it, that just wel-

Y/n: It sped up the process.

Cracking came from Y/n's knuckles as his tired body shook at the realization of what he had done.

Y/n: An-Another planet doomed. Destroyed by me.

???: What, weren't you trying to protect us?

Y/n: You. You should've ended me, I killed everyone on that planet. Your family, those you loved.

The blood stained teeth of Y/n grinded against each other harder by the second along with his broken and bloodied hand to grip the stone floor hard enough to indent it.

Y/n: Why the hell didn't you kill me!?

Confusion etched itself on the woman's face as the Saiyan struggled to breathe. There was an unnerving amount of silence in the air as the heterochromic woman thought to herself while looking away before readjusting herself and staring back at Y/n.

???: I didn't have the thought, you from what I heard protected us from the Viltrumite's. It was last minute as well since the planet was well, being destroyed.

Y/n: . . . .

???: Look I-I- We- I don't know if you're completely fine with this but we're the only ones left , I would've felt bad if I just left you to die. So this is just me paying you back for your efforts.

A roar in the distance was heard breaking their concentration of the that crept back into the conversation leaving the two to stare off towards the darkened jungle that spanned across the tree coated land.

The hardened exterior of Y/n relaxed, taking in the sight of the mysterious planet that filled him with a sense of calmness. It was foreign to the Saiyan, there was no blood flying at him, nobody begging to be spared from his terror, or any type of war or chaos incited by the strength held within him.

All he could hear were the crackles of the fire beside him and the calm winds that flowed through the air. Was this what the planets he conquered and turned to glass felt? What did he feel? What was happening to the Low Class Saiyan?

Y/n: . . . . . What's your name?

???: . . . . . Muezli. 

Y/n: Mmm . . . . . . . . I'm Y/n. Thank you.

Meanwhile

Location: Andromeda Galaxy II
Planet: Viltrum
Morning

To feel terror form a Viltrumite is to feel terror from a being of otherworldly proportions. Within the capital of the planet stood a building of unfathomable size, decorated in white and gold along with several of the empires flags waving about allowing the blood red symbol of the most powerful species in the universe be known to all who enter the planet.

Inside said building stood a room of red where the air shifted and look to be pouring down nothing but weight that crushed everything that wasn't the large man standing in the middle of the empty training room.

His fist clenched tightly as the air of the room pressed down on him even more seemingly holding the Viltrumite in place before the looming red lights turned off leaving the area to be completely consumed by the darkness and for a breath of air to leave the behemoth's nostrils.

Just then a door was seen opening allowing light to spew into the room and highlight the figure's defined and wide back. Kregg then quickly flew into the room and got down on one knee while bowing his head down.

???: Speak.

Kregg: Grand Regent Thragg, the Saiyan. The assault of Cereal left nothing but destruction and the death of four Viltrumites.

Thragg: And what of the Saiyan?

Kregg: We couldn't find his body, it was taken after the Cerealian's attacked Anissa and soon following the planet collapsed in on itself, or so it says on the report.

Thragg stood in silence as he repeatdly gripped his hand cracking the knuckles in it before raising his right arm up, staring down at it with a mute but curious expression.

Thragg: Do you believe he could live through that?

Kregg: From what we've seen, without a doubt Grand Regent.

Thragg: Then here's what will happen. You will alert every Viltrumite of his betrayal and tell every planet that we so much as passed by about his existence and that they must alert us of his presence on their planet.

Kregg: I'll make sure to put this plan into action sir.

Thragg: Good, and as follow on to that. I want names of planets that hold species that look akin to us and the Saiyan's he may try to blend in with them, and if they try to harbor him. Exterminate them but make sure to bring the Saiyan alive.

Kregg: Sir. I don't think that would be wise in the slightest, his strength continues to grow at a rate that would surpass even your ow-

Kregg stopped himself the instance Thragg turned his head back to the General allowing a deafening silence to creep over his body as the leader of his race spoke.

Thragg: I'm already aware of his growth General. But you forget we aren't so different from him, the Saiyan's are more explosive in evolution, but we are more tactful. It may take longer but even if he becomes the legend that inspired so many of his own to rebel against us, the technology he left in the wake of his escape will allow for us to turn the tide.

He then completely turned his body allowing Kregg to see the look of complete annoyance and held back fury within the Grand Regent's face making the fellow Viltrumite shake from the silent anger released from his ruler.

Thragg: Do I make myself clear?

Kregg: Y-Yes Grand Regent.

Thragg: Good. And make sure his son is still breathing, I want him to see his failure one last time.
