Also don't forget that Aokiji is ICE guys, there's a lot he can do to avoid Akainu's Magama throwing fist etc., Aokiji can literally slide on his like Surfing or some type, he can move incredibly fast if he does that. By surfing on his Ice to get close to Akainu he can hit him with Haki, I can imagine Akainu saying "How Annoying" blah blah
, but anyways Ice can do much more than Magma can even though the magma can melt it, Ice is slippery and Aokiji can use that to his advantage, and Aokiji can jump pretty high with his Ice, staying away from Akainu and launching strong attacks would be one of his best options. He may have done other stuffs too but Aokiji is/was an Admiral afterall, he must have had something up his sleeve, he couldn't have been an Admiral only by only having such a strong fruit, he must have had something else that helped him. Maybe that penguin had something to do with it? IDK
, but am pretty shure a fight with two Admirals facing each other wouldn't only last 10 minutes, more like 10 days like it was.
I can imagine at the end of the fight, Akainu's magma was surrounding Aokiji, and Akainu get's up and Aokiji probably thinks his going to end the fight by killing him, but instead Akainu just walks away also heavily damaged etc. that's how I imagined the fight ended
