I don't see how any of this is supposed to prove that Kizaru is Zoro's opponent when Fujitora is also an extremely proficient swordsman.
This isn't really relevant because Fujitora was not part of the Marines at the time, and you don't know who Fujitora would have been paired with at Marineford if he was an Admiral at the time. You also completely ignored Kizaru volunteering to stop Big Mom from sailing to Wano. Is Big Mom the second strongest fighter in her pirate crew?
This entire quote applies to Fujitora more. Fujitora has an unresolved conflict with Zoro. They clashed multiple times in Dressrosa and all their clashes were inconclusive. In fact, Zoro had a hungry and bloodlusted look in his eyes and he wanted to fight Fujitora again at the end of Dressrosa.
Do you have proof that Kizaru is stronger than Fujitora and Ryokugyu? Claiming Kizaru is Akainu's strongest subordinate when you don't have proof that Kizaru is stronger than Fujitora and you haven't even seen Ryokugyu's face is a very bold claim to make. You have no idea who the strongest between the three Admirals is, so please don't pretend that you do.
There is no misunderstanding. Kizaru does specialize in kicks. But Kizaru also specializes in shooting lasers and he also specializes in swordsmanship. Kizaru is a versatile fighter that excels in multiple forms of combat. You're the one who is ironically downplaying Kizaru by implying his only specialization is in swordsmanship and that his kicks are only fodder control.
Zoro vs Fujitora looks a million times more likely then Zoro vs Kizaru.
Incorrect.
Zoro has clashed with Fujitora on more occasions than Luffy is. I'm not even sure why you're bringing up Luffy because Luffy's admiral opponent is Akainu.
That didn't stop Fujitora from attempting to harm Zoro when he tried sinking Zoro into the earth with his gravity.
Baseless speculation. It's no different then your claim that Kizaru is stronger than Fujitora and Ryokugyu.
