Y/n and Big Mom clash again as it is getting very clear to Big Mom that Y/n is actually getting stronger.

Big Mom: No way...

Big Mom puts even more power in her attacks as they still continue to clash.

Big Mom: I guess I have to get even more serious now....or else he might actually just defeat me!

Big Mom: Mamamama!! Do you really think you will be able to defeat me!? You have no chance at all Y/n!

Y/n jumps back as he uses his advanced conquerors haki coating and his new Ryou as he just looks at Big Mom.

Y/n: As long as I am still standing...there will always be a chance of me defeating you!

Y/n starts to think about the Straw-hats and the people that he loves. He laughs as he spits out some blood.

Y/n: I will defeat you!!

Y/n blitzes towards Big Mom as she used her advanced conquerors haki coating as Y/n and Big Mom clash even more.

Y/n smiles

Y/n: I may have a chance to win! I...can do it!

Big Mom is also smiling as she is just reminiscing.

Big Mom: I haven't had a good fight like this since the Rocks times.

She smiles even more as she looks at Y/n

Big Mom: This brat....he is one of the top 10....no I think he in top 7 strongest people that I have ever faced. I need to put my life on the line to actually defeat him...!

Big Mom calls up some of her weaker crew members as she says one thing to them.

Big Mom: Life....or...

Big Mom: Death!

The souls of her weaker crew members start to form in her hand as it becomes a ball of just souls.

Y/n: And what are you going to do with that?

Big Mom: *Laughs* I'm going to eat it.

She eats the condensed ball of souls as she jus increases in height as she looks down at Y/n.

Big Mom: Mamamamama!! You are finished now Lunarian Y/n!! I am a lot stronger now. So prepare to lose!

Big Mom: I have never felt this much pain in a long time...this where you die. Y/n!!

Y/n is panting and breathing heavily as he looks up at Big Mom

Y/n's whole face is just bloody as he just looks up to see a upscaled Big Mom who looks way, way stronger then before.

Y/n: This is going to be a challenge....but its worth it in the end!

Big Mom's conquerors haki just starts to flare and burst as Y/n has to use his own conquerors haki to clash with it.

Big Mom then decides to use Napoleon as she goes to Y/n as she tries to slash him as she slashes him the chest, causing him to go back.

Y/n ignores the blood as he comes right back with his advanced conquerors haki coating as he slashes Big Mom causing her to go back a bit.

Y/n: I guess she has even more endurance and durability now...

Big Mom laughs as she looks at Y/n

Big Mom: Mamamama!! This is getting really good isn't it...Lunarian Y/n!!

Y/n smiles as he looks at Big Mom.

Y/n: I was just about to say the same thing!! Big Mom!

Even though he wants to continue fighting, he is breathing quite heavily as he realises that he is losing a lot of blood.

Y/n: This is going to be a big ch-

Thunder happens as Y/n gets struck by lightening in the shoulder as he even gets slashed in the chest as he just looks up into the air and falls onto the floor. Blood is just all over.

Big Mom: Mamamama!! I guess its time to put you in the dust Y/n!! Tenman Dai jizai Tenjin!

The Lightning strikes the ground  as the whole ground just starts to crumble and shake.

Y/n: Oh shi-

A bunch of lightning just hits Y/n and the terrain as he gets absolutely shocked by the lightning.

Big Mom: Is he dead?

The smoke clears

Y/n is just knocked out as blood is just around him.

Big Mom: It was a interesting fight Y/n...I will give you your respect. But I guess it wasn't enough to defeat me.

Big Mom starts to fly off as some of the higher ranks of the Big Mom pirates make it to the bloody battlefield

Amande: Y/n-kun...tried against Mama and failed..

Galette looks down at the ground.

Galette: Its such a shame...he was so cute as well..

Oven: Mama did it!! She defeated that pesk of a pirate!!

Amande and Galette look angrily at Oven

Oven: S-sorry about that..

Oven: Lets celebrate!!

Everyone starts to walk off as they start to hear something as they turn to see conquerors haki just bursting

Y/n: Even though I'm on my last legs...don't cast me out like that.

Y/n slowly gets up. Bloody all over he removes the flame on his back as he blitzes at Big Mom with his advanced conquerors haki coating as he slashes Big Mom off of Zeus.

Oven: Ahhh!! He came back and hit Mama!!

Big Mom is shocked

Big Mom: You still have some fight in you...? Let me beat that out of you!

She runs at Y/n as she uses her armament haki and tries to punch and combo Y/n. Y/n uses his ryou as he cancels a bit of the attack power but it still hurts like hell.

He comes back in as he punches Big Mom's arm as it caused it to break a bit.

Big Mom: You..!!

Y/n gets grabbed by Big Mom as he gets punched and punched over and over again with her advanced conquerors haki coating as he is bleeding a lot

Big Mom throws Y/n in the air as she uses Napoleon as she just slashes Y/n in the chest as he goes flying down to the ground.

Big Mom: You were a worthy opponent. Just stay down-

Purple conquerors haki just starts to burst as she turns to see Y/n...but in a completely different form.

Y/n: This is my final and strongest form...

Big Mom looks at Y/n in shock

Y/n: This is my penultimate form. Come at me.

Y/n: Big MOOOOM!!

Thanks for reading!! Yes I decided to add Y/n's hybrid form in this form! Don't think I forgot about it!
