[Discussion] So Mashima really had zero idea what to do with Acnologia from the very beginning huh?
Acnologia's first mention was when Zeref randomly mentioned him (I cant recall if Gildarts said the name first but whatever) on Tenrou for...some reason? We later learn there is ZERO connection to them in any way shape or form but the series made it seem like it was one of his creations that he lost control of. We also later see him be confirmed by that one knight dude at the tournament, yet it was then reversed and stated not to be true. So it seems like Mashima originally had the idea of it being a Zeref creation that even he feared to just being its own standalone Dragon that the anime had to fill in the lore with because Mashima really had no idea what to do with him at that point. His death is also incredibly lackluster lol.
