Kaido went through a gauntlet, Luffy is on his 6th round, he is still going to extreme diff and might even take another L before ZKK.
Luffybros: Luffy is so strong, he can beat his entire crew.
Reality: Luffy gets one shotted by Zoro.
Let's just hope he is now strong enough to beat his next opponents in one round, and won't need Zoro to finish them for him. I guess that's reasonable considering we're "near" the end. No more than two rounds, please Oda, enough is enough.
