If Hybrid Kaido cannot beat G2/G3 Luffy, then yes.
King of Hell Zoro's AP >> Hybrid Kaido.
Hell, Rooftop Zoro already had better AP feats than Hybrid Kaido (solo, so. Hakai not included).
Hybrid Kaido's Haoshoku clad Thunder Bagua was shrugged off by Law of all people.
If Zoro outclasses Hybrid Kaido AP wise, then he wins.
Zoro was already able to blitz Hybrid Kaido and scar him before awakening Haoshoku and while far from top condition (half dead, 30 broken bones and no stamina left).
What do you think happens to Kaido if Zoro blitzes him again, but this time it's a maximum Haoshoku coating attack?
Pray tell, how exactly is Hybrid Kaido supposed to win here?
To summarise:
- Zoro has the offensive prowess to fuck Kaido up severely.
- Zoro has the CQC ability and attack speed to land attacks on Kaido.
Hybrid Kaido simply can't win with his pitiful solo showings. Portrayal can only carry someone so far.
