dude... enough with the OP stomps FT threads... Natsu cant do CRAP to Akainu. Even if he tried to swallow his lava, he hasnt been shown to be able to take it yet. Not to mention Haki and Rokushiki techniques. this is a stomp.
Lightning dragon Natsu(Unlimited) when he is battling hades + Dragon Force (Unlimited) + Unlimited magic ( mana, stamina or whatever you call it that makes a magic power unlimited so he will not get tired when using dragon force and lightning dragon ) + Second Origin
And natsu MIGHT just MATCH akainu.
