There would be no point in misleading the audience with Doriki if the Zoan fruits just messed it up completely. Lucci was far superior to Kaku period. Luffy himself pointed out that Lucci will kill everyone if he isn't stopped by Luffy.
But fruits literally did mess it up, lol.
It grants them animal-enhanced muscles and size, instantly boosting their physical power.
Unless you think base Lucci and hybrid Lucci have the same physical power, lol...
Lucci in base was almost twice as strong as base Kaku, yes. However, neither fought in base form.
Forget what Luffy said, Franky said that if Luffy didnt stop Lucci, >
some of them might die.
Zoro one-shots Lucci even without Asura. Zoro already matched and overpowered Bigan.
And Bigan is far higher Doriki than any move in Lucci's skillset.
He also trashed Amadenachi which is also higher Doriki than anything in Lucci's skillset.
Asura was needed for that but low diffed nonetheless.
The cat is lucky that Zori didnt cross its way in Enies Lobby.
I repeat, everyone looks menacing in front of Luffy.
Nobody looks menacing in front of Zoro.
Kaido one-shots Luffy. Kaido+Big Mom cannot one-shot Zoro. Worlds apart...
