I have a possible spoiler:Swords clash for a moment, before one overpowers the other. Someone (most likely Ichigo) is slammed through multiple buildings and back into the water. Shirogetsu looks with blank eyes. Ichigo: Shit shit shit! They are too strong!
Shirogetsu: Is that all you got Ichigo? Have you not improved the last time we met? Where's that drive? Where's your instinct, Ichigo?!
Ichigo: Shut up! I'll beat you and make you teach me what I need to know! I'll do it to protect my town!
Shirogetsu disappears and reappears in front of Ichigo's face.
Shirogetsu: You have a real problem with keeping your focus on the battle. Shirogetsu grabs Ichigo's face and throws him the other way Let's change that!
Shirogetsu's blade starts to glow, with a mixture of white and black reiatsu swirling around in his blade.
Shirogetsu: You wanted to see the Final Getsuga Tenshou? Fine. But you'll have to live first!
Shirogetsu charged towards Ichigo, with a close-up in Ichigo's face; a look of surprise and fear
Deicide 15
–- Switch to Hueco Mundo
Mayuri looks upon the battlefield with a look of slight disgust. Close-up on Byakuya and Kenpachi's face. Kenpachi looks beaten up and a noticeable disappearance of his eyepatch. Byakuya has lost an arm, and looks on the verge of collapsing.
Kenpachi: Feeling a bit light-headed, Byakuya? You can take a break, I'll cut this guy into pieces for ya.
Byakuya: Your insults are as barbaric as your mindset, Zaraki. I have no need for your help. My patience is simply wearing thin.
Mayuri: You both are taking too long. How hard is it to take down a complete oaf such as that?
A large figure towers over Byakuya and Kenpachi. It's Yammy still in his release form. He has scars over his chest from the constant barrage of attacks. But overall he seems unharmed.
Yammy: Hahahahaha! You fools can't even get past my Hierro! Is that all you got, or should I crush you like the insignificant little bugs that you are?
Yammy continues to laugh, but feels a bit off. A curious look is on his face, as if he's feeling something within his body. He crashes down upon his knees, clutching at his chest. Byakuya and Kenpachi look at this with a surprised look on their faces.
Yammy: What the- WHAT THE HELL DID YOU DO TO ME, YOU LITTLE FUCKERS!?
Mayuri: Oh, you didn't notice? See, while those two were running around trying to attack you, I had already used my bankai, but with a few modifications. You should be feeling the effects right about now.
Yammy roars in anger as he feels an intense amount of pain.
Mayuri: I figured a brute such as yourself would be hard to take down. So I modified my bankai using one of my test subject's labs. Bunches of bacteria go in and infect your body, though they work differently for each person. I guess in your case…they'll be liquidizing your insides.
Yammy coughs up blood, but smiles.
Yammy: You think…you think this is going to kill me? You motherfucker. You crafy little motherfucker. I'M NOT GOING TO DIE, BECAUSE I'M YAMMY FUCKING RIYALGO!
_Yammy's body starts to mutate. Grotesque bone spikes sprout from his spine. Bone spikes sprout from his shoulder, forearms, and wrap around his chest. The smokescreen covers the rest.
After a bit, Yammy's true form is revealed. He's reverted back to normal size, but he's shirtless, with bones sprouting from his body. He wears a dinosaur-like skullcap on top of his head, and he roars, sending Byakuya, Kenpachi flying backwards with his reiatsu alone._
Yammy: To think you fuckers made me revert to my true form. Now I'll show you all the power of a vasto-lorde.
