Winding up some off-topic in the chapter discussion/prediction thread...
You know, we probably shouldn't assume that Dragon's DF is weather / wind related, when Dragon may not have a DF.
I agree, but the Devil Fruit explanation is by far "common sense".
Everything Dragon has done so far (at least in manga) could probably be explained with "haki", the general all purpose answer to pirate's difficult problems in one piece.
Uh!

"Haki" - no, not this time. Haki has already been explained as ability or power to either predict things, enforce attacks/defends or to create such will power to make others faint by its presence only. There hasn't been any explanation that people would be able to control elements or things by haki.
You are forgetting the flashback of Skypiea. It's a bit different since they lived 400 years before the current story line but still, it shows that a character with important place in a Flashback can die.
And before Whitebeard's and Ace's deaths it seemed the only place. Now even Bellamy seems most likely dead already.
That seems like a cleaning error due to the bad paper quality of the Shonen Jump to me. In the tankobon which is much cleaner by default that shadow on "future sabo"'s face
looks like this. So there isn't that typical line of Sabo's glasses.
Most try to go by the hair, buddy.
Hey everyone I know this post shouldn't be in here but I know that some of you may be interested. The new One Piece anime episode (ep. 453) that came out shows stuff that haven't been shown in the manga as of yet.
You're wrong - it already was within several covers. Everything beyond is just filler, most of Franky's stuff even
contradicted the manga.
