Bruh akainu - Kuzan feat is nothing given it was 10 day serious fight where BM and Kaido were holding back and had sibling like relations. Even holding back their fight was going to destroy the island eventually. Oda can't have onigashima destroyed.
Also official literally says Kaido would have smash the island to pieces.
Dude even going all out they didn't destroy the island.
Also this is how chat gpt translates the dialogue:
“Are you planning to turn this island we finally got into a ruin!?
You bastards!!
A team like this will fall apart sooner or later anyway…!!"
When asking it about the smash it to pieces part:
"The word 廃墟 (haikyo) refers to a ruined, desolate, or abandoned state — like an island left in shambles or neglected destruction — but not necessarily something being physically blown to pieces.
There’s no direct language about breaking, smashing, or exploding the island.
It's more about the outcome (the island ending up as a ruin) rather than the method (e.g., blowing it to pieces)."
But really even if it did say that,we still have characters saying "do you want to destroy the whole island" and then it's just them destroying buildings. Until we actually see it,it doesn't mean much.
