So since Saturn is the top guy in the enemy force heading to Egghead, that means
Luffy vs Saturn
Zoro vs Kizaru (strongest underling)
right?
Depends on how Saturn is used:
1. If hes not strong, then nope, hes just here to take the Serephim.
2. If hes strong, then it depends on two further factors:
A. Is he here to just take the Serephim? Then no, he may not fight anyone outside of a showcase.
B. If he has presense to challenge Luffy, then yes.
So we'll see. Kizaru himself may not even let him fight
