Yes they will obviously come back before you ask here’s the theory.
Theory:1
I think that Kidd can use the sword at the bottom that huge ass sword and stab through kaidos body. This will make it a mutual hit and make kidd be taken out for some time.
Theory:2
Zoro would get a big slash on kaido this will make kaido use thunder bagua against zoro like a mutual hit.
This is the easiest way for the first person to be taken out the fight. Someone gets a huge blow against kaido in turn they get the consequence of being the first taken out the fight.
