You love Zoro ? Aren't you
I'm simply stating the facts.
Remove Zoro, and guess what?
Apoo would defeat Luffy.
Yamato chains would never be freed.
The numbers would defeat some of the alliance.
Queen destroys the live floor.
The alliance never get the antidote.
The most of the alliance on the live floor would die.
If Kid, Killer, and Law manage to make it to the roof(Even lets say Luffy makes it with plot armor). They all would die.
If Marco helped capture the antidote, chopper would not be able to make it in time.
Queen would not be so cautious.
Marco may be able to hold off the virus but Queen can use other viruses because his gun wouldn't be destroyed.
King and Queen would defeat Marco. Sanji would be defeated.
King would destroy the remainder of the alliance. Scabbards would have to fight calamities, and would lose.
Big Mom and Kaido wouldn't even break a sweat.
Kaido would come down and clean shop.
Yamato would have her ass beaten.
Momo would have to retreat.
