Predicted title. "The Evolution"

*Starts off in Hueco Mundo.*
Yammy is bleeding from where he got slashed and has his hand covering his face in pain.
Yammy: You Fucking bugs! How dare you do such a thing,I'll smash you into pieces!!
Yammy swings his tail at Kenpachi and Byakuya.
Byakuya and Kenpachi easily dodge this attack
Kenpachi: Damnit when is he gonna die already? He's startin to piss me off!
Byakuya: Only a savage like you can lose his temper so quickly.
Kenpachi get's more annoyed
Kenpachi: You know your startin to piss me off too Byakuya! Don't make me cut you!
Byakuya:If you can that is.
Byakuya and Kenpachi start to fight.

Mayuri looks at them with amusement and grins.
Mayuri:My,My their like cats and dogs,always competing against each other.
Mayuri then looks to Yammy.
Mayuri: That espada said he was "Espada Zero" but what i find interesting is that why is he so weak compared to the ones Byakuya,Kenpachi,and myself fought,or is he not showing his true power?
Nemu:Not showing his true power?

Yammy slams his fist into the ground and makes it shake.
Yammy:That's It!! I had enough with you damn insects!!
Byakuya and Kenpachi stop fighting and look at Yammy.
Yammy: You think I am weak don't you?Don't you?!?
Yammy releases a lot of heavy reiatsu.
Yammy: Well your DEAD wrong,you see if an espada is strong enough,he can contol his evolution rate.

Kenpachi:Evolution rate? what the hell is that?
Yammy:Right now I am an Adjuchas level arrancar.
Yammy starts to glow with his own reiatsu and gets bigger and bigger.
Byakuya:What is this?
Kenpachi:His reiatsu is gettin stronger!
Yammy:Let me show you what a REAL vasto lorde looks like!!!
Yammy explodes causing the reiatsu to go off flying into a swirling vortex.

*Scene goes to Ichigo and Unohana.*
Ichigo's bankai outfit is half-complete.
Unohana:You know Kurosaki you remind me of a powerful shinigami that i used to know.
Ichigo:Yeah,that Kaien Shiba guy right? People say I look and act like him.
Unohana looks at Ichigo.
Unohana:No not Kaien,you are a lot like him,but he is not the man I am talking about.
Ichigo looks confused.
Ichigo:Then who?
Unohana:The man you remind me of is,previous Captain of Squad Zero,Isshin Kurosaki.
Ichigo looks shocked.

*Back to Hueco Mundo.*
The smoke from the explosion almost clears up and there is a human-shaped figure standing there.
Kenpachi:Who the hell?
Kenpachi then gets slashed across his torso.
Kenpachi:What the hell?!
Byakuya and Mayuri are shocked to see this.
Byakuya:What in the world?
All three captains look at the shadowy figure.

Yammy:Now,you shall expierence the fear and despair when you fight a vasto lorde!!
Yammy is now human-sized with nothing covering his torso(no shirt),he has white armor covering his waist down(they look like skinny jeans except with white armor),with two claws clinging on his sides,his hands are now claws,his hollow mask is his sharp teeth,he still has red markings under his eyes and his hollow hole is still the same,but he has horns,short white hair,and his sclera is light purple and his iris is completley black.

End.
Hope ya like it!
