Dude there is no fixed ZKK Scenario Theory
Some think it Zoro vs Kaidou which ends with Zoro victorious
Some think it's just Zoro jumping & beheading Kaidou on top of capital just like Ryuma
Some think it's SHs vs Kaidou which ends up with Zoro's Finisher
Some think it's Ice Oni Zoro beheading Kaidou
Some think it's Zoro executing Kaidou
Some think he uses 1 Sword Style & other say he uses Asura
... etc
All that matters is that ZKK = Kaidou dying at hands of Zoro
Everything else are just details we cannot predict & each one gives their own Scenario
every scenario you mentioned is just a bit nuanced than others and nothing significantly different except for the SHP collab which is whole different thing ending the same way
There is a reason why Ryuma is bought up as a core part of the theory as a really meant to to be kinda thing.. The legend of ryuma repeats through Zkk innt?
if its not that then the theory itself is in space at this point.. zkk itself is knows as a solo feat that yall put forward in whatever shape it may be i get it.
if its not a ryuma parallel then the premise is kinda redundant innt? and why would oda have zoro recover after the hell he's been through and will be through soon enough after the drug wears just for him to slay a fleeing Kaido just for the sake of the parallel.. what is there to achieve doing that... ofc its a possibility.. but its a very overrated one... blown out of proportions and justified through and based upon misconstrued jargon
exactly why ZEK exist to do that possibility justice coz it doesn't need to justified narratively so there is nothing to base it upon "if it happens it happens" is what it runs on.. but this still is different from the zkk many rant about here and it seems like many want it for the sake of it.. and it still not guaranteed no matter what version os the theory zoro kills Kaido yours or mine
its something you can only pretend that happened due to your so called judgment and act like you got it right... and its something i can take it seriously only when it happens.
the zkk as a theory and its vast versions... are based upon re engineered bias.. and shaky lores that honestly are misinterpreted and don't suggest a relevant link or symbolism
.
it's a 50/50..
and the coin is in Oda's hand..
and you know which 50 I'm betting on
