Luffy and Ryo knock down kaido, it was clear that, the attacks they used where both strong enough to knock him down by themselves
Kaido: (why did their attacks work on me)
Big mom: you're still saying that! I'll crush you! King of the pirates! Don't make me laugh! Stop napping you scaly old dolt, is this a joke to you once punch form those runts and you're on your knees
Zoro: A new Haki, must be the technique that old man taught him, Ryo had it before but he's mastered it now
Kid: his punches can hurt kaido, but there's gotta be a trick, what the hell is it
Zoro: Ryuo
Kid: what's that?
Zoro: a different kind of Haki that destroys the enemy from the inside
Kid: sounds nasty, I like it
Killer laughs: We might just win this
Law: that's nice and all but first there's something I gotta get straight with Strawhat
Big mom: Hey rubber shrimp! You don't even know what it means to be king of the pirates, it's not something you take lightly so stop running your mouth
Kaido gets back to his feet
Kaido: (I took them both down in Kuri, how did they both get so much stronger, they barley even got my attention, I crushed them but there's something I overlooked, few can stand up too me 'flashes of Roger, Whitebeard, akuma, oden, xebec and shanks' and they are not to be underestimated, I know you both didn't come here just to lose, are you telling me you think you're both as good as them) ANSWER ME! I crushed you both and yet you believe you have a chance of defeating me right now, all fools standing before the king of beasts, are you both so arrogant to think you've earned this, well we shall see, worororo
Ryo: You know what you cow gorilla, I've been thinking, I'm order for luffy to become king of the pirates I need to become a king in my own right
Kaido: is that so?
Ryo: yeah! I've decided instead of making a title for myself, I'm going to steal one, 'he raises his hand and points at kaido' and it's gkojg to be yours get ready to bow before the next king of beasts!
Kaido grinned and laughed: Well then, come and take it!
Ryo licks his lips: oh I plan too
The brothers stare down kaido for a while
Before they all let out a burst of Haki and it clashes, neither of them faltering
Then they both get a flash of the future and kaido is suddenly charging at them
'Ryo uses flash step combined with Luna dance to jump right over the attack'
Kaido: Thunder bagua!!
The shockwave blows him back but he catches himself and skids along the ground
Luffy: dammit I saw that one coming
Ryo: yeah but he's fast
Kaido turns around grinning
Kaido: well done, it's an improvement over last time if nothing else
Big mom: come on kaido honestly, brats are meant to be incinerated
Big mom calls on Prometheus and blasts a heavenly fire right at the,
Zoro then rushes in and in the blink of an eye
Zoro: fox fire style! Flame rend!
Prometheus is cut in half!
Big mom: he cut Prometheus right in half?!
