I wanna discuss which of the three admirals is the strongest. Aokiji is in my opinion the weakest, and Kizaru and Akainu are nearly on the same level. Akainu with his Magma could easily beat Aokiji but Kizaru could not defeat Aokiji. But Kizaru and Akainu could only harm each other when they use Busoshoku Haki. But i think Akainu is the strongest one because his Powers can easily defeat other powerful devil fruit users like Ace, Whitebeard and probably Jozu.
