ZKK was wrong, but there were many plot threads pointing to it that Oda just abandoned in Wano.
It's not the case that there was no basis for ZKK:
There's a reason many Zoro fans considered Oda's handling of Zoro's character a disappointment. Powerscaling and the ZKK agenda aside, Oda just abandoned many of the threads he set up involving Zoro:
I do not regret my ZKK threads. Given the evidence available at the time, there was a strong case to be made and I'm okay with having made it.
I don't really have much investment in Zoro's character anymore. Oda really just didn't follow through on Zoro's character in Wano.
Like Yamato vs Nakama was another theory that had a very strong basis but which Oda didn't execute on:
I advocated for both theories and I don't regret it.
They weren't baseless or unfounded or sheer wishful thinking.
Insomuch as theorising has any basis at all, ZKK and Yamato 4 Nakama were some of the more well founded theories.
It's not the case that there was no basis for ZKK:
- A look at Inherited Will in the Land of Wano
- An analysis of the Oden's will to slay Kaido and open Wano's borders, passed on to his Scabbards and to Roronoa Zoro through Enma.
- The Second Advent
- "Sword God" Shimotsuki Ryuma, Shimotsuki Zoro, and Dragon Slaying
- Long Live ZKK
- Reasons to still believe in ZKK after chapters 1010 - 1012.
- Kaido Must Die
- The narrative necessity of Kaido's death.
- No, Zoro is NOT "Done" After Defeating King
- Zoro still has more to accomplish in the Wano arc in order to bring his character arc to a truly satisfying conclusion.
There's a reason many Zoro fans considered Oda's handling of Zoro's character a disappointment. Powerscaling and the ZKK agenda aside, Oda just abandoned many of the threads he set up involving Zoro:
- The second coming of Ryuma/Ryuma parallels in general
- The comments that perhaps the legend of Ryuma slaying a dragon might be replicated
- Kaido's statement that there would never be a monstrous samurai of the likes of Kozuki Oden again
- Zoro saying he would round up the samurai
- Zoro wanting to visit Ryuma's grave
- The plot with Shusui in general, Ryuma said it was that sword's will that Zoro wield it, and then Oda just had it replaced and never gave Zoro any closure
- Zoro's interest in the Nidai Kitetsu
- Zoro's lineage
- Zoro seeing the Grim Reaper/death
- Zoro getting recognised as a hero
- Etc.
