So according to you he was talking about thier fraction when Zoro's name droped Kaido twice when he says who they're going to defeat? Mhhhh OK bro.
Show me panels of when Zoro has ever done this to any other antagonists in the series. Whoops you can't.
Stop crying bro, he's taking part in the fight regardless of your feelings. And even if you were to exclude every parallel Zoro has with Oden and numerous hints in the manga as to why this will occur he would still be up there cus Luffy ain't soloing Kaido.
