Burning Desire of a Super Saiyan RE ( Male reader x Kefla )

Defend the Future

After returning to the Seventh Universe, Y/n opted to use Instant Transmission to return to Earth while Whis filled Beerus in on the situation.

~ Earth ~

Y/n arrives at Capsule Corporation via Instant Transmission, and Caulifla and Kale, who were talking to Future Trunks, run over to him, smiling.

Caulifla: Hey, you just up and left! Where'd ya go?

Kale: T-Trunks told us about Black...

Y/n: Whis took me to Universe 10, and I noticed that someone there has a very similar energy signature to Black.

Future Trunks pipes up, a curious expression on his face.

Future Trunks: You did? Who is it?

Y/n: A Kai named Zamasu, when Whis and I got there he was ranting about me becoming some kinda villain.

Caulifla: What?!

Kale: W-why would he think that?

Y/n: From what I've gathered, he's weary of mortals...

Future Trunks: Sounds like he's paranoid.

Y/n nods and rubs his chin in thought.

Y/n: Question is, why is his energy signature similar to Black's? Black was talking about his body as if it wasn't his... You don't think he took my body somehow, do ya?

Future Trunks: There's no real way of knowing right now, but either way... We should head back to the future.

Y/n: Right. Caulifla, Kale, I know I just got back but I'll spend time with you two soon, okay?

Caulifla huffs, but nods and Kale nods as well.

Kale: I understand... Y/n.

Y/n pulls both girls into a hug and they hug him back as he lets them go, then joins Trunks as they enter the time machine.

Y/n: With Black being able to use Ultra Instinct like me, this won't be easy

Future Trunks: All we can do right now is hope for the best.

He presses a few buttons and the time machine starts up before traveling into the future, time and space distorting around it before everything stops, and a bleak future is revealed. The sky is an ominous blanket of shadow and the city that was once full of life and bustling with activity was now in ruins. The hatch of the time machine opens and they get out, Y/n, taking in the sight of the future, Y/n felt bad for Trunks, for everyone here, it was awful.

Future Trunks: Alright, now that we're back-

A gunshot rings out as a bullet zips towards Y/n, who catches the bullet without even looking at it, it had been shot from behind them.

Future Trunks: Damn, nice reflexes.

He the calls out.

Future Trunks: Hold your fire, this man isn't Black.

Y/n drops the bullet onto the ground as a voice can be heard.

" Trunks, it's you! "

A woman climbs out from behind some rubble, and several men also reveal themselves as she walks over to Future Trunks.

Future Trunks: Mai, you're alive! I'm glad!

He takes her hand in his, smiling at her, and she blushes and looks away. Y/n clears his throat and Future Trunks releases her hand and he laughs nervously.

Future Trunks: Alright Mai, you and the others need to get out of here, once you do, don't come back here. It won't be safe soon.

Mai nods and turns her attention to the armed men surrounding them.

Mai: You heard Trunks, let's move out!

The men all nod and begin evacuating and Mai turns back to Trunks, smiling.

Mai: You better not die on me.

Y/n: Don't worry Mai, he won't.

Mai nods, feeling reassured by Y/n and she also evacuates the area, after about five minutes, Y/n speaks up.

Y/n: Time to get his attention.

" That will not be necessary, Son Y/n. "

Y/n and Trunks look up to see Black, who was smirking at them from the rooftop of a building. He hops down and lands in front of them.

Y/n Black: I am most pleased that you have come to this timeline, Son Y/n.

Y/n: Is that so?

Y/n Black: But of course, for you see, you of all mortals are the most blasphemous. You use the power of Ultra Instinct, but it is not yours! It belongs to the divine.

Y/n: So you decided to take my body for yourself, right Zamasu?

Black chuckles and claps, his smirk never leaving his face.

Black: How perceptive, Son Y/n. I made it my mission to wipe out all mortals, but my own body lacked the necessary strength to do so. But your body, Y/n... It can withstand the strain of Ultra Instinct and you can use it fairly well. However, I couldn't simply use Ultra Instinct just because I stole your body. No, I found out as much as I could about you. Your mindset, your training regimen, your strengths and weaknesses... Even your origins.

Y/n: My origins? What do you mean?

Y/n Black: I found myself wondering why an Earthling of all creatures would be able to acquire and utilize the divine Ultra Instinct technique, after all, your species is largely weaker than say, the Saiyans... However, you are a clear outlier. You...

He points at Y/n, his smirk never leaving.

Y/n Black: Are the reincarnation of a Destroyer God from a universe that was wiped out by Zen-Oh. It all made sense then, of course you could use Ultra Instinct, you are a God reborn. So I then used the Super Dragon Balls to swap bodies with you, after all, I no longer had use for my previous vessel, so it was of course destroyed, along with your mind and soul. And thus I began to exterminate mortals, learning to control this magnificent body along the way... This body is perfect for Ultra Instinct, and when you showcased your might to me before, I understood how to truly grasp the power of Ultra Instinct, so I must thank you. It is you who have served me so well in destroying these wretched mortals!

Y/n's eyes widen and Trunks seems surprised as well.

Y/n: How do you know all this? And why take my body specifically, why go through the trouble of learning to control Ultra Instinct when there are fighters on my level, like Jiren?

Y/n Black: I have no interest in any normal mortal, cleansing the filth that is mankind should be done by a God, so a Godly power is of course what I chose.

Y/n grits his teeth, trying to keep himself calm.

Y/n Black: And now, I have the perfect opportunity to increase my power further!

Y/n: Zamasu... How dare you take my body?!

Black simply chuckles at Y/n's rage.

He then closes his eyes and Trunks takes the opportunity to rush him, but Black appears behind Trunks, wrapping his arm around Trunks' neck but he lets go as Y/n hits him from behind, he then turns his attention to Y/n.

Y/n Black: Fine, I won't toy with him in front of you.

He then powers up into the same Ultra Instinct state Y/n had achieved against Jiren, his aura, eyes, and hair were pure silver.

Y/n takes a deep breath in and slowly exhales as he also takes the same state, and he and Black stare each other down.

Black: I hope you're ready, Son Y/n... I will kill you!

Y/n: You're not the first to try that line on me!

Black takes a fighting stance that resembled a mix of Y/n's and Zamasu's while Y/n takes a fighting stance similar to the one Goku took when he fought Vegeta.
