Law is going to join the strawhats as a crew member because his entire crew was killed by blackbeard's crew member doc Q. He will then join the strawhats to fight the Blackbeard crew.
During the time skip Robin became an agent for Dragon, giving him updates on his son. The last poneglyph is blank and can only be "read" by someone who can "understand all things" like Roger and Luffy.
I agree with ^, except I can only imagine Luffy going to the last Poneglyph and saying "Aaaaaaaah, Mystery stone"
Corazon is sabo!! He is actually alive. And this is crazy. But here's my theory. So consider it maybe?
There was no time where Sabo could've been close to Law!
When do you guys think that Vegapunk doctor will show up and explain the origin of the devil fruits?
First thing : the fight between akainu and aokiji is a set up. In order to trick who ? BB might be the target of this plan. The other part of this plan could also be to have aokiji working on tracking lvl 6 impel down ancient prisoners.
Second thing : zorro might not be the one to defeat Mihawk. Imo he will be the one to defeat the one who took down mh.
i've got a crazy theory in here at marinford mihawk said that he understood luffy secret power, i think i figured out what he means it goes like this :
this one hit me when watching an episode at the current dressrossa ark when luffy used conqueror's haki on the bull and suddenly they became friends, i think that's luffy secret power.
we all know that this type of haki is heavly related to personality and and the one word that luffy keep using even more then "i'm gonna be the pirate king" is guess what "nakama" so heres luffy secret power all along the anime/manga he unconsciously use his conqueror's haki to make those he encounter his friends ,that's one hell of a power if you ask me, i also think that usopp is doing the very same thing but in a more epic way ,we've seen so far that almost in every ark his lies become true as in when he said i'm the captain of 8000 pirates guess what in the manga in the dressrossa ark they call him god-usopp and allmost all the freed pirates worshiped him even briefly though, the main point is usopp just like luffy is propably using conqueror's haki to command respect from them.
this one sounds twisted but it's fun to speculate
Big Mam ends up destroying SAD factory and this causes a Yonkou war with her and Kaidou, leaving DD off the hook for the moment.
Doflamingo will become a rouge to the World Government, afterwards. Strawhats will be labeled a serious threat by the WG and a bounty will placed on them so high, everyone will be coming after them.
The grandline is a mountain chain like the red-line, and they are connected like counter-weights; at the end end the red line will sink (completly or just half) and the grand-line will rise; turning the world upside down
Law will make luffy immortal with his dying breath, telling him the story of D. And that luffy has inherited the will of D. And will be the one to stop the world government.
Eustass "Captain" Kidd has the CoC Haki.
