Hmm looks like Big Mom is much more involved in the battle than i thought from the earlier spoilers. This is a pure brawl battle, everyone is in it. Killer's new attack look very impressive, no wonder he said he was stronger with his punisher blades
It looks like he took heavy damage from Big Mom's attack though.
Both Kaido and Big Mom sensed the power behind Zoro's attack(with Kaido sensing Oden in the blade), and looks like Luffy is the one who remained standing after Big Mom's attack and is about to make them pay
