Speaking of the One Magic, do you think Acnologia already has it, had it or he's searching for it? Cos' it seemed like he ruled the world pretty easily and what else do you have left to do after ruling the world? Also, why not try ruling the world in those 400 years when there were (I'm presuming) no dragon slayers around or at the very least only a few?

BTW, do you think Acnologia has a specific or special type of Dragon Slaying Magic or is it just Dragon Slaying Magic? Although the manga wasn't clear on this, in the anime the Dragon Roar he fired on Tenroujima looked like Aetherion/Ethernano...
