Kaido didnt specifically refers to Kidd, Law, and Luffy. Also zoro and Killer was there in the first place so they do are counted. I repeat, by default, Kaido referred to all of them. So it's your headcanon saying Zoro and Killer werent counted
Anyway, i don't have any high stakes on the little monsters thing, i don't care much about that. I'm only interested in showing that Oda played on the three captains / two first mates dynamic this chapter, so he must be a Zoro hater, or some Zoro fans can fuck off calling me that for sayin that he's going to do it.
