Y/n starts to gain conscience as he starts to look around at his surroundings

Y/n: Oi....where the hell am I?

???: So...it is you! Oni Y/n!

Y/n is tied up on the floor as he looks up

Y/n: Who In the world are you?

Big Mom: You don't know who I am!? I am Big Mom! The Yonko!

Big Mom walks up to Y/n

Big Mom: I've heard a lot of things about you...and how you have been taking down marines left right and centre!

Y/n: Yep! That's me!

Big Mom: YOU!! You have been attacking Marines that I PAID!! to bring sweets to me!!

Y/n: How was I meant to know. A marine is a marine. Every single one of them are filthy

Big Mom: Well. You interrupted my Sweet imports. So I'm going to kill you!

Pudding: Kill him Mama!! He deserves it!!

Y/n: Shut up!! I don't want to hear anything from you. How dare you just betray me like that!! I thought we were friends!!

The last part sticks with Pudding as she looks down to the ground.

Big Mom: I guess it is time for you to be executed!! Napoleon!!

Big Mom throws off her hat as it transforms into a sword

Napoleon: Yes mama!!

Big Mom smiles as she goes to slice Y/n. Y/n jumps towards Napoleon as Napoleon slices the ropes that Y/n has been captured with.

Y/n: Alright!! Now I'm out of here!!

Y/n grabs his Kanabo as he quickly starts to run.

Big Mom: Everyone!! Go after Oni Y/n and capture him alive!!

BMP 1: Yes Mama!!

Time skip

Y/n continues to run until he makes it to a open green area.

Y/n: Okay! Now to finally get a boat to get out of here!!

BMP 2: We have found him!!

Y/n turns around and sighs as he sees a bunch of people coming towards him

Big Mom: You are not escaping Oni Y/n!!

Y/n: You really want to catch me that bad!? Alright then...!!

Y/n smiles as they get even closer to him

Y/n: I guess its time to fight!

Y/n runs towards them as they run towards him. He starts to swing at the Big Mom pirates with his Kanabo as he goes by each of them one by one.

Y/n: Comeon!! You gotta try hard-

Y/n was taunting but he gets punched. He goes flying into the grass.

Big Mom: I guess I will take care of you myself!!

Y/n: I will defeat you!

Y/n blitzes towards Big Mom as he jumps into the air

Y/n: THUNDER BAGUA!!

The electrified Kanabo hits Big Mom but she just blocks it with her arms.

Big Mom: Ah! So you are using Kaido's move? When Kaido uses it it's quite strong....but for you it's quite weak...!!

Big Mom uses her arms as she pushes him back as he goes tumbling on the grass.

Y/n: I have to try again...

Y/n readies himself as he goes to attack Big Mom again as she blocks him again. This continues for a bit until...

Y/n: Take this..!!!

Y/n goes in for another attack on Big Mom as she just smiles and this time blocks it with one hand

Y/n: Again!!

Y/n goes to attack her again

Big Mom just grabs Y/n's Kanabo

Big Mom: Weak!

She breaks the Kanabo as she throws it and Y/n flying

Y/n: Damn....I-i might actually lose...but I've never lost..!!

Y/n blinks as he sees that Big Mom is right in front of him

Y/n: Well...I guess I am finishe-

Big Mom throws Y/n in the air and starts to just combo him. He starts to bleed heavily as he gets punched in the face.

Y/n: H-how am i meant to combat against this...!!

Before she sends him flying. She grabs him by the Face, Slams him down on the floor and starts to scrape him against the One piece Earth. She then throws him back up into the air

To which she then just barrages Y/n in the face as that sends him flying into one of the walls in Whole Cake Island.

Big Mom: Now!! It's time for you to die!! Oni Y/n!

Y/n slowly gets up as he is bleeding all over

Y/n: I won't give up...I-i..WONNT!!!

A burst of power is seen as multiple Big Mom pirates are just knocked out

Big Mom: Conquerors haki!?

Y/n takes the opportunity as he grabs two swords from some of the Big Mom pirates as he runs towards Big Mom

Y/n: This is my final attack!! Thunder Bagua!!

Y/n uses the two swords to slice Big Mom as she bleeds a little bit (As in a little bit.)

Y/n: I have to run...!!

Y/n drops the swords as he starts to run. He turns around to see that noone is chasing him.

Big Mom: Sweet Generals!! Get him!!

Y/n turns around to see Smoothie, Cracker and another person standing in front of the ocean.

Cracker: I'm sorry but you are not going anywhere!!

Cracker goes in to attack Y/n but he just luckily dodges as he jumps over Cracker's defences.

Y/n: One down. Two more to go!

Y/n is in the air as he makes it to Smoothie

Smoothie: I have to do this Y/n-san!!

Smoothie swings her sword at Y/n but he dodges it as he is going straight towards Smoothie

Y/n: Sorry!!

Y/n accidentally kisses Smoothie as she starts to blush. And with that he continues to run away

???: You are not escaping.

Y/n gets caught by Mochi as someone appears

Katakuri: You will be executed by Mama.

Y/n: Sorry! But I have a adventure to go to!!

Y/n transforms into his four armed Oni Form as he starts to melt the Mochi.

Y/n: Fire and Electric barrier!!!

Y/n uses both his fire and Electric powers to create a wall separating him from the Big Mom pirates.

Y/n: See ya around!

Y/n detransforms as he runs towards the ocean as he finds a small little dinghy as he takes that and goes out to sea.

Y/n: OIIIIII!!! BIIIGGG MOOOOM!!!

Y/n shouts as he is sailing away

Y/n: ONE DAY....I WILL COME BACK HERE AND DEFEAT YOU!!!

Big Mom laughs
