Luffy vs Kizaru would rock, but, trust me, if Kuma, Vegapunk, and SSG are there in Elbaf, the amount of "Cook vs Kuma" theory because "muh Judge vs Vegapank!" and "muh science warriors!" theories will rival even Cook vs King theories, before the inevitable Cook vs Sentomaru happens because of feet vs hands.
I'm all for Zoro vs Kuma, though, especially if he is upgraded by Vegapunk to be an actual WSC (World's Strongest Cyborg). So he will be a physical beast like Bullet but can use Nikyu-Nikyu powers.
That way, ZKK will happen twice. I'm sure you know what the second ZKK stands for, right?
Interesting.
I do, however, think Aokiji's leaving the Marines was legit, though. The scenario may eventually call for him to betray BB because Aokiji does not seem to be a person who is willing to work with an amoral sleaze like Teach (too big a moral jump for Kuzan), but I think he is legit not working under Akainu whatsoever (too many opposing views going back over 20 years between them). I think the theory of Aokiji being affiliated with Sword holds more water, especially if Sword is meant to be a group that aims to reform the Marines from within.
Also, with Ryokugyu's introduction, what do you think are the chances of him getting jumped by both Cook and Yamato instead of Cook alone? Or do you see Cook getting one final upgrade to finally propel him to low top tier and extreme diff Ryokugyu?
