Remind me, what killed kaido? What hakiless thing penetrated kaido’s skin that for a normal fighter you need acoc for?

That’s right, magma. Akainu is gonna be so busted, I see no reason for him to be weaker than kaido. Akainu is guaranteed to fight Luffy in the final saga. Final saga opponent of Luffy>regular opponent of Luffy. Zero reason for him to weaker than Crydo.
