To this day the mental gymnastics they went through to make ZKK possible in their heads.
Zoro doesn't need to fight King that's beneath him.
Zoro will heal up and head back to the rooftop.
Zoro was knocked out when Luffy said he'd return he doesn't know he'll go up to fight Kaido 1 v 1
Luffy will beat Kaido and go unconscious and Zoro will behead an awakened Kaido who will come back stronger than ever.
The beheading of the magma dragon wasn't ZKK!!!
Hilarious
