To give context for the combination attack, "覇海”(Hakai), the first kanji 覇 (ha) is obviously used in the dorry and brogy attack, Hakoku, but is also the first kanji in 覇王色の覇気 (conqueror's haki or supreme king haki, which ever translation u prefer.) It is also the first kanji for haki as stated above. The word hakai is also a pun, as 破壊(hakai) means destroy.
For now, Kid and Killer will stale Kaido for some time, cause Luffy and Zoro are kinda down right now or at least need a break. Marco comes top and heals them up, right in time when they need to switch with Kid and Killer. Then they will switch for 3-4 times, always a bit improving. But then Luffy tries to finish, goes full goat G4 and attacks. It doesnt went well, so he goes hakiless for a few minutes (less then 10). Zoro standing there alone against Kaido and right when Kaido goes all out on Zoro, he gets disturbed by still damaged Killer. So Zoro + Killer open the Scars of Kaido and buy the time for Luffy and Kid to get fit. Damaged Kaido is mad then, bleeding after the opened Scar and attacking Killer and Zoro, both heavily damaged and near death. And right when he wants to finish them off, he gets pushed back by CoC!
He looks up, madness in his face, pure hate.
In front of him, Luffy and Kid, both fit again.
"You are going down now."
Dope as hell, but I don't want Marco to heal them... King already let Zoro go up, he will look really and extremely bad if he lets Marco go on the rooftop, heal them and then go back to fight him. Maybe Marco will try and in that moment King will turn into hybrid form and stop him
