This is the pre 2017 explaination which was headcanon as we had no other way to explain it
Katakuri proved that to be horseshit
Akainu simply shaped his body to dodge the attack
Even IF that’s true, how does prove he has future sight? Future sight means you’ll see the Akainu coming but Akainu was surprised. He also couldn’t see an attack from Turtlebeard coming
Probably. Not sure how that relates to what I said, there's no way Roger/WB traded blows for 3 days either given they were barely injured when the fight ended, same for BM/Kaido. Most of these long ass fights involve clashing attack after attack and landing very little blows.
He does not have the elemental advantage. Oda directed film Z in which Kuzan freezes a Volcano's eruption and Ice can freeze magma if before being melted if it's cold enough
Magma=Ice
