NO ONE'S POV:

(Y/N jumps up from the hole he's in.)

(Y/N): Overhaul!

Overhaul: I thought I took care of you already.

(Y/N sees Nighteye & Midoriya have been impaled.)

(Y/N's thoughts): Not again! I'm still not strong enough to protect anyone!

(Flashback of Kirishima & Y/N at Fatgum's agency.)

Fatgum: Okay, Kirishima. How about you, (Y/N)?

(Y/N): Well, I want to become strong enough where no villain can knock me down! I...want to become strong enough to protect my friends.

(End Flashback.)

Overhaul: Finally, it looks like one of you heroes had finally decided to give up!

(Y/N's thoughts): What kind of hero can't protect his frie-

Midoriya: Mt. Man! We need your help!

Overhaul: Shut up!

(Y/N suddenly gigantifies himself.)

(Y/N): [yelling]

Overhaul: Another hero that relies solely on power. Just like your friends, you don't know when to give up either. Though there's something to be said for a person who refuses to admit defeat.

(Overhaul uses Nemoto's Quirk to speak to Eri.)

(Y/N): Leave her alone! Sizeless Dash!

(A normal sized Y/N suddenly appears in front of Overhaul.)

Overhaul: When did you-

(Y/N): Ascending Uppercut!

(Y/N gigantifies himself as he's uppercutting Overhaul.)

Overhaul: All you heroes keep touching me!

(Y/N's thoughts): I can't let him touch me.

(Suddenly Ryukyu & her interns come crashing in.)

Uraraka: Mt. Man?

(Y/N): The others need your help!

Tsu: If Deku needs our help, then how'd he tell us to come down here?

(Y/N's thoughts): No time figure out what they're talking about!

(Y/N): I'll finish Overhaul!

Overhaul: You heroes ruined everything!

(Y/N): This is the end, Overhaul! Sierra Strike!

(Overhaul absorbs the Hassaikai giant but as he does Y/N's Sierra Strike hits Overhaul which sends him into the sky & Y/N jumps up to follow him.)

(Overhaul & Y/N are now in the sky.)

(Imagine Y/N is in front of Overhaul.)

Overhaul: Ugh, not just power, what's your Quirk?!

(Overhaul uses Nemoto's Quirk.)

(Y/N): Gigantification. I can not only grow in size but I can also gigantifiy any limb on my body.

(Y/N): Why'd I tell him that?

Overhaul: Hmm. I must say you've impressed me.

(Y/N): Just shut up!

(Y/N & Overhaul begin trading blows. But Y/N isn't landing as many hits as Overhaul.)

(Y/N's thoughts): Crap! I'm getting tired. But I can't let up now. I can end this-

(Overhaul punches Y/N right on his scar from the stab wound.)

(Y/N): [yelps]

Overhaul: I found a weak spot.

(Y/N): It doesn't mat-

(Overhaul grabs Y/N by his throat & begins to rapidly punch the spot where Y/N's scar is.)

(Y/N's thoughts): It's no good.

(Y/N): (coughs blood)

(Y/N's thoughts): I'm losing it...

Overhaul: You were Eri's favorite! It's gonna break her heart when she sees your corpse!

(Y/N): Overhaul!

(Overhaul throws Y/N back to the ground.)

*RUMBLE*

(Y/N): I'm sorry, Eri...He beat me...

(Y/N sees Midoriya in the sky.)

(Y/N): Midoriya? And is that...Eri on his back?

(Y/N coughs more blood.)

(Y/N's thoughts): Shit...Midoriya, please. You have to beat him!
