Soon You had gotten Information from Gigantomachia that All for One was pretty much holding A Base of Operations in the Mountains, so you teleported others there to try and confront him. You saw A Giant Door blocking your Way.

Y/n: A Giant Door Huh? No Problem. The World Government can't even use those to Hold Me Back.

You then walked up to the door and Just Blew A Hole threw it.

Y/n: Okay that is Good. Now Let's see If they-

Just then You were confronted by Shigaraki, Dabi, and Himiko!

Y/n: Hey Guys I was wondering-

Dabi: WE'RE UNDER ATTACK!!

He then Launched a Blast of Blue fire at you as you Just Ate it!

Shigaraki: Really?

Dabi: Sorry I Kind of Lost my head as soon as he showed up.

Y/n: Okay where is All for One?

Himiko: Who Cares anymore?

Y/n: You sound... Depressed. Something Happened. What is it?

Himiko: Twice Died, and I Lost my eye. Nothing Matters anymore.

Y/n: Um... That's... Sad.

Shigaraki: Well to get to All for One you Must get past all of us first. 

Y/n: So, Where's everyone else?

Shigaraki: Oh, He's not putting all of his eggs in Single basket. It's as easy as that.

Y/n: Hm, Good Point. So, It's A Three way fight then?

Dabi: Exactly, You Fucking Moron! You can't win this!

Y/n: Let's see that actually Happening. Come at me then.

Dabi: TAKE THIS!!

He then Launched A Giant Fire Blast towards you as you Summoned the Master Sword!

Y/n: Fox Fire Style: Crossing of the Six Paths!!

You then cut through the Fire and slashed through him as he fell down defeated!

Y/n: Next time don't live so fruitlessly.

Shigaraki: TAKE THIS! TEXAS SMASH!!

Y/n: Gear 3!! Gum Gum Elephant Nail Gun Gattling!!

You quickly overpowered his attack and you then appeared behind him with A Quick karate chop to the back of his Neck he fell to the ground Beaten!

Y/n: Don't want to Kill you Man. You Must have one Hell of a Sad backstory from what I've heard, and I feel sorry for you. So Himiko You want to fight?

Himiko: No.

Y/n: You Good?

Himiko: Of course not.

Y/n: Let me Help you.

Himiko: Huh?

You then removed your eyepatch, and you removed your own eye and gave it to her planting it into her own eye. Of course, you Regrew your own eye with the Powers still intact.

Himiko: Y-You gave me your eye?

Y/n: No Problem at all. I can Just regrow it Like that. I Just did. 

Himiko: So... (Blushing) I have A Part of you now?

Y/n: Sure, I Guess. You better leave Now. I'm going to destroy this Place.

Himiko: (Blushing) Thank you...

Y/n: Good, Now be Careful you have A Sharingan Now!

You then ran deeper into the base as Himiko Just Blushed.

Himiko: (Blushing) Thank you Y/n-San... Thank you very Much...

You then ran into All for One's room as you slammed the doors Open!

Y/n: ALL FOR OOOOOOOOOOOOOOOOOOOONE!!!

All for One was sitting there drinking A Glass of Wine as he smiled.

All for One: Ah Y/n. I Guess you found out.

Y/n: Why?

Y/n: Why did you Torture Ayoma so Much?

All for One: To Be Honest My Own Personal Gain. I want to destroy you and Unleash my Evil, Vile, Horrific Plans upon the world.

Y/n: And That is?

All for One: To Get rid of you once and for all, and then I shall Kill everyone you know and Love.

Y/n: Seems Cliche.

All for One: Silence your Tongue!

He then activated Like 50 Strength quirks at once turning his arm all Muscley and massive as he smiled, and you smirked back.

Y/n: You Know, I have gotten stronger Myself.
