POSSIBLE FORESHADOW OF STRAW HATS STEALING PONEGLYPH FROM KAIDO

We all know that you can just steal a paper from people who wrote down what’s on poneglyphs, but what does Luffy think about it?
He is not happy with that, given that he showed us his Donald Trump face.
So, how can they steal poneglyphs? Can they just carry them? Well, I think there are 2 images that foreshadow this.
First one:
[​IMG]
Wadatsumi is carrying a Poneglyph on his head.

Second one:

Look at the pattern on Luffy’s clothes – the Kozuki clan.

But what kind of significance does the clothing bring, you may ask
Well, try to remember who from Kozuki clan ate a very strange fruit, and since the day he ate that fruit, he could turn objects that are put on head into clothes.
Still doesn’t ring a bell?
This guy:

They have a foolproof plan – they steal poneglyphs by literally wearing them, and then Kanjuro, with Usopp’s help, draws a new Poneglyph where the old one was so no one can suspect a thing! I think it’s a perfect scheme.

    Law And The Voice Of All Things

    After last chapters, many people in OP community started speculating that the fact Momonosuke is hearing a voice makes him somewhat related to the ability of hearing Voice of All Things!

    Most likely, the main hint is this panel, that may be a reference to Roger, the one we know for sure that had this ability:

    Actually, way ago (December 21, 2015), I’ve done a theory video in my channel exposing my ideas that Inuarashi and Nekomamushi knew Gol D. Roger, that we would have a Poneglyph in Zou and that most likely Roger was able to “hear” it.

    Seems like, maybe, some of my ideas can be proven right in the near future. If not, well, by the time it was a good theory xD, haha.

    Anyway, one think that REALLY caught my attention and people aren’t commenting is Law’s expression while climbing the tree.

    Why is he so uneasy? So unconfortable? And why did Oda (which clearly is trying to faster the story’s pace) make sure he showed Law’s expression to us?

    Also, inside the tree, while everybody’s freaking out with Raizou, Law is still uneasy. It can be due to the awkward situation, but maybe not. Also, we can’t asure he’s looking at Raizo instead of the Poneglyph, which is supposed to be from where the “voice” comes

    Anyway, if Law can “hear” the the Voice of All Things too, it open possibilities:

    – Gol D Roger
    – Monkey D Luffy
    – Trafalgar D Water Law

    So…. does it means that this ability is related to the D clan?
    Anyway, Luffy never heard a Poneglyph (although he seems to have the ability to hear the Voice of All Things). Is this ability something that you awaken somehow or train, something like that?

    Second interesting topic: does this mean that Momonosuke (and the rest of the Kougetsu/Kouzuki family) is a D???

    Well… guess we’ll learn a little more about it all by the chapter that’s coming tomorrow.

    Thanks for reading

      ZORO AND LAW “THE BADASS DUO” VS JACK INCOMING

      After the recent chapter, many people believe that we will propably have a Jack vs Strawhats showdown and i am one of them!

      But, i still believe it’s gonna be a seperation between the strawhats!

      Luffy will take few people with him(I believe except for Pekoms, Raizou will join him as well) and Zoro with Law will prepare for the trip to Wano!

      However, there is a small obstacle… none other that Jack himself…! and i will explain why…

      We know that he went on a rescue mission to save Doflamingo from getting imprison!

      In addition, we know he is heading to Impel Down!

      Now, let’s look the map…

      As you can see,Impel Down is on the west while the strawhats are in the opposite direction(east/Zou).

      We know that Jack , managed to attack the marines before reaching Impel Down!

      Also, we know that he left the island the same day Doflamingo was defeated!That was 11 days ago…! And base on chapter 807(ten days ago) half of the strawhats reached Zou!

      So, if i have to take a guess… the distance at that time(It’s a moving island) between Dressrosa and Zou was approximately 1-2 days at most!(read chapter 807 , it will help you understand how many days has passed since entering the NW!Base on my calculations they are 14-15 days)

      Taken into consideration the analysis i just made, it’s highly possible that he managed to catch up with the navy really quick!

      If we also take into the account that the navy left Dressrosa the third day after the battle…!2

      It is beautifully adds up!

      In my opinion, Jack managed to catch up around here!

      In the proccess managed to sink two ships, but sustained some injuries and considered dead…

      However,he failed to retrieve doflamingo and base on the last chapter, he is alive and by the looks of it, he is been accompanied by a large fleet!

      So, guys let’s refresh our memory!

      What was his initial mission?
      To retrieve Raizou!
      And where he is now?
      He is on Zou!
      So, what he is going to do?
      He is going to complete, his unfinished mission!

      I think it’s a pretty logical way of thinking , don’t you think?

      Even if he wants to go somewhere else, he has to pass to Zou…!

      I think it’s very unlikely to move on , straight to Big Mom’s tea party… I doubt he even knows anything about it…

      Also, take note that the battle between him and the navy occured around 8 days ago(11-3=8…xD)!

      He had 8 whole days to rest,to heal,to prepair(fleet)and to travel back on Zou to put an end to his unfinished business!

      So, he must be pretty close to Zou!

      That means a SHOWDOWN!I can feel the hype!:)

      In my opinion, since there is the Sanji matter on one hand and the Jack matter on the other , they will have no choice but to split!

      But why split and not go all together to save Sanji?

      1.Luffy said he will go alone, although i doubt he will be completely alone… he will take at least two![Pekoms and Raizou(stealth)… they will sneak!]

      2.I think it was foreshadowed that, it’s going to be a match between Zoro vs Jack!
      a)They both are the right hand man of their captains!
      b)They both use swords as weapons
      c)When the minks were talking about Jack, Oda focused on Zoro twice for a reason!c011

      3.There is no way Zoro, will go after Sanji after making that speech1

      4.The strawhats befriended the minks and i don’t think they will leave them at their fate…Luffy will entrust Zoro with the mission to protect them any way he can!I believe Law will stay too, since his good friend Bepo is from Zou!Let’s not forget they are still many of them injured

      5.Lastly… maybe one of the biggest mysteries… the moon!
      We have yet to be relieved , what happens when the full moon is out!

      I think i gave you some solid points!

      To move on with the last part of my theory!

      The last part of this theory will be a speculation, but if you think about it , it will might make some sense!

      I think in this fight we will have a Law and Zoro vs Jack battle, like we had the Law and Luffy combination against Doflamingo!
      So, this combination could be turn out to be true!

      Also, they are similar in personalities…both badass,cool,serious and bloodthirsty when they fight!

      In my opinion, this duo will be amazing!

      To conclude, i think we will have a big revelation regarding Zoro’s past from the moment he will release his demonic spirit!
      Yes, i think this will be the fight that we will see him go all out!

      This will be the moment when Zoro will trully connect to Wano and it will ignite his desire to go to Wano even more and learn about his past and lineage!

      I don’t know how the fight will turn out… but i believe , during this fight Jack will tell him about his demonic/cursed clan or lineage and to how he might connect to one of his future enemies!

      I hope you enjoyed my theory

        KOUZUKI FAMILY’S LINKS WITH THE ANCIENT KINGDOM

        Recently we were introduced to the Kougetsu family, which was re-named the “Kouzuki” family.

        Kou + Getsu = Deep Red/Crimson + Moon

        Kou + Zuki = Light + Moon

        However, with deeper searches, I found out that Kou also means “Scarlet”:

        Kou + Zuki = Scarlet/Light + Moon

         

        Notice how Kouzuki/Kougetsu are both associated with the Moon.

        The Red Poneglyph & The Kouzuki Family Crest

        Seeing as how Kouzuki can mean “Scarlet Moon”, and scarlet is a deep red colour, I wouldn’t be surprised if the Kouzuki family were the ones who were involved with the creation/placing of the Red Poneglyph in Zou.

        If this were true, then it would mean that they had strong links with the Ancient Kingdom.

        Interestingly, the colour red is usually affiliated with happiness in Japanese culture, unlike Western culture where it represents negativity (danger, death etc…)

        So what if the Red Poneglyph doesn’t tell us of any thing bad, but rather, something good:
        I was thinking that it might’ve talked about how the Kouzuki & Minks became united due to the AK helping out. Just speculation though.

        We also know that Wano has no links with the World Government, its fighters being so strong that they even scare away marines.

        This would mean that during the Void Century, the 20 Kingdoms were perhaps unable to invade and destroy Wano Kingdom – thus the Wano may know a lot about the happenings of that time since they survived.

         

        Luffy interested?
        Luffy rarely ever cares for such things.
        Usually he starts snoring, picking his nose, or outright says he doesn’t care.

        It’s interesting that Oda chose to show Luffy being actually interested in what “Kouzuki” is.

        Most of us can agree by now that the Ancient Kingdom was probably alien in origin, possibly coming from the moon.
        “D. = Half-Moon Theory”

        Clover’s Illustration Of The Ancient Kingdom

        [IMG]

        Look at this:

        [IMG]

        Don’t the 8 balls surrounding the bigger ball at the centre of the crane resemble the 8 phases of the Moon around Earth?

        Defo interesting. Another link with the Moon.

        Furthermore, the crane crest may be based on the real life Daimyo crane crest:

        [IMG]

        I found out that it’s also the symbol for the Japan Airlines:

        [IMG]

        Could the Kouzuki’s Kamon represent freedom?
        The red represents happiness.

        Additionally, the Tsuru Kamon (Crane Family Crest) is usually affiliated with royalty in Japan.

        Look at this:

        There are several Crane-Kamons on Luffy’s kimono – could this have been a foreshadowing of the Kouzuki, or also, have been a foreshadowing of Luffy being of royalty.

        It’s a common theory that Luffy is descended from Joy Boy (King of the AK), and thus is of royalty.

        If we dig deeper, it could be a link between the D. People (AK People) and the Kouzuki.

        Since the Crane-Kamon is common in Japan, it could just be a coincidence.
        But we know that Oda doesn’t add things for nothing.

        [IMG]

        Remember this?

        How about this?

        [IMG]

        Seems familiar.

        Seeing as how the first symbol represents the Celestial Dragons, could the second symbol represent the Ancient Kingdom?
        Or more particularly, an important ‘sub’-symbol of the Ancient Kingdom.

        Seeing the links between the Kouzuki Family and the Ancient Kingdom, I wouldn’t be surprised if the main royalty (Oden & Momo) of the Kouzuki Family are actually D. in origin.
        By D. I mean being descendants of the Ancient Kingdom.

        As we know, the Ancient Kingdom had a unity of different countries (e.g. Fishman Island, Shandora etc…), so since the Kouzuki were likely part of that unity, their main royalty could’ve been related to them.

        Momonosuke, like his father, can hear the “Voice Of All Things” (perhaps Law too since he’s drawn silent in the same row), and Neko & Inua say that someone else they remember could too.
        It could’ve been Roger.

        Seeing as so far all of those who could hear the Voice Of All Things are D. People (descendants of the AK), then perhaps the main royalty of the Kouzuki Family are descendants too.

        8 Races = 8 Balls

        Here we see 9 different Races.
        But since the Fishmen and Merfolk live together, we can count this as 8.

        If not the moon phases, could the 8 small balls in the crest be a reference to these 8 ‘Races’.

        This is all speculation though, as so far we haven’t gotten too much info on the Kouzuki Family.

          Kuma’s Intention

          Myth: Kuma separated the Straw Hat Pirates so they can become stronger.

          Zoro,_Luffy,_and_Sanji_Attack_PX-4

          Fact: The full reason behind Kuma separating the Straw Hat Pirates is still unknown though a great deal of evidence seems to point to this myth being proven at least partially true.

          By Chapter 591, it was revealed that Kuma wished to save the Straw Hats. Sentomaru also stated that the user of the Nikyu Nikyu no Mi can control where to send people, which was also proven by the fact that Perona was sent to a dark castle like she wanted. The Straw Hats then landed on suspiciously convenient spots (like Zoro ending up on Mihawk’s island and Nami on an island dedicated to studying the weather). This evidence strongly supports the myth’s veracity. Even so, until it is confirmed, this cannot be taken as a fact.

            Romantic Relationships in One Piece

            Myth: X character in One Piece is in love with X other character in One Piece.

            Fact: It is not uncommon to see pairings mentioned like Luffy x Nami, Luffy x Boa Hancock, Sanji x Nami, Zoro x Nico Robin,  however some fans try to force the speculation into fact when it is not.

            Fans love to fantasize about possible character couples.

            lxb

            When asked if there would be romance in One Piece in a SBS letter, Eiichiro Oda replied “they are in love with adventure”. There are no hints released in the manga itself. There exist minor love stories such as Kyros and Scarlett’s love story and certain relationships have been addressed (such as Piiman, Tamanegi and Ninjin mentioning how Usopp is a “lucky man” to have somebody as Kaya) but they are rather minor and no major relationship has been officially confirmed. As such, most love referencing comes in the form of perverted comments from one character to the other. Oda said that since this is a shonen manga, there is practically no romance (with a few exceptions, such as married couples, etc.) Not counting Sanji’s feelings towards almost every female being in existence, Oda took eleven years to introduce any form at all – Boa Hancock’s love for Luffy. However this is considered to be a one-sided romance solely intended for humor as Luffy does not have those same feelings for Hancock, having turned down her marriage proposal several times in the past. Oda also mentioned in one of the SBS that One piece is manga targeted at young boys, therefore there will be no romance between the straw hat crew.

              FORESHADOW OF ZORO’S ARC IN ONE PIECE COVER PAGE!

              When I was going through all colored cover pages, some of the pages got my attention. Those pages had “SH with Samurai costume”. So I searched all cover pages and arranged in chapter vise.

              In Chapter 70 cover page, left bottom, below Usopp, there is a face. When I see that face, suddenly I remembered “Kin’emon” face.

              Oda already designed or thought of samurai in his mind.

              After in Chapter 310 cover page, right bottom of page. I saw “SHIBARAKU” word. So I searched it. But that searched result shocked me.

              Shibaraku is among the most popular pieces in the classical Japanese dance-drama. The plot centers around the figure of Kamakura Gongorō Kagemasa, who has become the stereotypical bombastic hero of the classical Japanese dance-drama, with red-and-white striped makeup and strong, energetic movement. The historical Kamakura Kagemasa is famous for his bravery for having continued to fight after losing an eye in battle in the Gosannen War (1083-1087).

              Kamakura Kagemasa lost one eye in Gosannen War. Zoro also have scan on his Left eye. Zoro may not lost his eyes but his eye is definitely injured from someone. Oda may have taken only plot of this Shibaraku play and adding his own idea and creativity, story may be different. Or Zoro may open his left eye while battling with enemy in Wano kingdom and he may eventually lose his eyesJust my prediction according to the source of SHIBARAKU play).

              [​IMG]

              Kamakura Gongorō Kagemasa (鎌倉権五郎景政) (born 1069) was a samurai descended from the Taira clan, who fought for theMinamoto clan in the Gosannen War of Japan’s Heian period. He is famous for having continued to fight after losing an eye in battle during that war.

              We still yet to know full background of Zoro, since some people are saying, “He is the incarnation of Ryuma”. So, Zoro might have been a descended from one of the clan’s in Wano Kingdom.

              Now we will talk about Gosannen war. The Gosannen War was part of a long struggle for power within the warrior clans of the time.

              So lets assume that, “Wano kingdom will be having Power struggle between clan’s and one of the clan approached Kaido for support since wano Kingdom is not under WG. When KAIDO came to wano, he will defeat other clan members and finally he will cheat the clan which hired him. So after that Kaido will take control of Wano kingdom.”

              Let’s continue with our SHIBARAKU drama – The climactic moment of this dram takes place when a goodly samurai is being assaulted by a number of villains. Kagemasa shouts “Shibaraku!” (Stop a moment!) loudly from behind a curtain (agemaku) and then steps out onto the hanamichi (a raised platform extending through the audience to the stage) in magnificent costume and makeup. Arriving at the stage, he sits on a stool (aibiki) and, in a special kind of monologue called tsurane, explains his story. He then drives the villains off.

              We already know that, Kaido’s men’s are chasing that Kagetsu Clan members with Kin’emon, Momonoske and Kanjuru. As per current situation, SH will divide as two group and one group with Luffy will head for “Whalecake Island”. Another group having Zoro will advance to Wano kingdom.

              Oda again, foreshadow the fighting between Zoro and Wano clan members.

              In Chapter 526, We can see. Tiger and Dragon are seeing each other with killing intent.

              [​IMG]

              Through Kin’emon, Oda again foreshadow the fight in chapter 816.

              Last but not least:

              -In chapter 547 cover page. We can see all the pirates in Samurai costume, who are all escaped from Impel Down. We may expect Crocodile and Mr 1 inwano kingdom as well as Jinbe(we need new member to fight with Kaido).

              -In chapter 582 cover page. While SH are playing game, we can see a cat wearing thrown in cover page. It indicates “Master Nekomamushi”. He may eventually join SH for his revenge.

              -In Chapter 710 cover page. Usopp and Chopper are in different costume. Especially Usopp(in old man costume). Usopp may use this costume in Wano Kingdom for hiding himself, like in Water 7 how he used a mask.

                CAPTAIN YORKI IS STILL ALIVE

                A bizarre statement, right? Well, there is a little bit of evidence scattered across the manga that indicates he may still be alive. In fact, he may be this guy:

                [​IMG]

                It’s popular belief that this guy is Scopper Gaban, the Second Mate of the Roger Pirates, but there is no reasoning for this at all beyond the assumption that the hat he is wearing comes from Wanokuni.

                There is some logic behind my thesis. Firstly:

                • The entire ‘From the Decks of the World’ cover story only contains characters the Strawhat Pirates already know. They do not know Gaban.
                • This means that the mystery man is also known to at least one of the Strawhat Pirates, and yet Oda hides his identity because it is very important.
                • Laboon is happy. This is very bizarre given his idiosyncrasy of bashing his head against the Red Line when waiting for the Rumbar Pirates. Why is he enjoying himself?

                Yorkis favourite drink is Sake and his favourite song is Binks Sake. What are they drinking in the cover page? Sake. He’s also friends with Crocus, obviously, and they are on friendly terms. The cover story shows characters celebrating the fact the Strawhat Pirates are not dead. These covers celebrate specific characters’ being alive, for example, the cover story mostly features old close friends:

                Luffy

                 

                Zoro

                Nami

                Usopp

                Sanji

                Chopper

                Her close friends are all dead – Robin

                Franky

                His close friends are all dead, right? – Brook?

                But that’s wrong! Brooks close friends are not all dead. He has Crocus and Laboon! If you connect the dots it’s perfectly plausible to think that’s Yorki, right?

                But wait, isn’t he dead? – UNCONFIRMED! We’ve already had an instance in which a presumed dead character has returned, and Oda even hinted at this. Remember Sabo?

                [​IMG]


                But Oda didn’t hint at him still being alive!
                Oh?

                [​IMG] [​IMG] [​IMG]


                The only confirmed conclusion we can actually make from his “death” is that the crew partially split up. In fact, Brook told Yorki to “treasure his life”, which indicates he would live on but would simply be unfit for Piracy. A common misconception is that everyone else contracted this disease when in fact they all died from poisoned wounds:

                [​IMG]

                Plus, the virus is “unknown” and it’s clearly never explained as to whether he will die or not. I speculate that he made the journey across the calm belt and, during the timeskip, completed his promise to Laboon. Do you guys think it’s possible for Yorki to be alive? I certainly do, I think that old man (with the same hair colour as Yorki) drinking Sake (his favorite drink) with two of his friends (Laboon and Crocus) at Reverse Mountain (where he promised he would return) is in fact Yorki in his 80’s.

                [​IMG]

                Note: Captain Yorki is also based on Calico Jack, his name is actually Calico Yorki. Calico Jack made a disappearance from Piracy only a few years after he became famous, he later returned from his Hiatus. I won’t go into immense details but Yorki’s own journey parallels that of Calico Jack who supposedly became ill.

                Am I being a lunatic or am I making sense?

                  NAMI’S FINAL POWERUP, THE ULTIMATE CLIMA-TACT

                  [​IMG]

                  As you know Nami has consistently been fighting with the clima-tact, however i do not believe the clima-tact has reached it’s final form yet. That is why i believe Nami well gain an ultimate clima-tact.

                  WHAT WILL HER POWER BE
                  Well i have had 2 ideas

                  • The ability to create iron clouds and merge them with her thunder clouds, to create a destructive lightning-

                  -Ohm’s weapon is made of iron cloudsword

                  [​IMG]

                  • She breaks up her new clima-tact; and straps each piece to her body. When this happens, she will be able to release thunder clouds just by moving; however she will gain a lightning tolerance and won’t be affected by the shock. She will then use fishman karate to manipulate the clouds.

                  I personally think both of these would be good clima-tact power-ups, since they would require little to no charge up time; something that all her attacks need.

                  FISHMAN KARATE-ENHANCED CLIMATACT
                  This clima-tact works by Nami breaking up a clima-tact(not the clima-tact she currently has) then strapping each piece to her body. With this she will be able to create different clouds depending on how she moves her body. She can then use fishman karate to create different techniques such as tornadoes, hurricanes and lightning punches

                  I believe this would be a good power up for Nami for a couple of reasons.

                  1. She doesn’t need a huge distance to be effective- for most of her attacks, she needs to keep a distance since it takes a few seconds to create lightning and in those seconds she is very vulnerable. But with the new clima-tact, she won’t need to run away from her opponents to gain distance. Rather she could run towards her opponent; by moving her body she would create more thunderclouds around her, she could then use fishman karate to use enel-like techniques by launching all the lightning clouds at her opponents.
                  2. Would increase hand to hand combat, Nami is really bad at this so it would help her a lot; it would also allow her to use CoA more effectively

                  IRON CLOUD-BASED CLIMA-TACT
                  This clima-tact works by creating island clouds inside itself, compressing the island clouds; then creating iron clouds, which can be turned into thunder-iron clouds to give them lightning properties. How would she make a clima-tact like this? Well if you didn’t know, island clouds are created by sea stone 

                  This leads me to believe that she will get a sea stone clima-tact. I believe this is very likely because the SMILE factory is coated in sea stone and when it’s destroyed Franky will most likely take that sea stone to make weapons. I also believe she will use a breath dial, as sea stone only creates island clouds when a certain compound is released due to high temperatures. With this sea stone clima-tact, she will be able to create large amounts of island clouds rapidly. Then due to the narrow space inside the clima-tact, these island clouds would be compressed and turned into iron clouds. She could then spin the iron clouds rapidly to turn them into iron-storm clouds that shoot lightning.
                  Here are just some of the techniques that she could do with this:

                  • iron-lightning blasts; same thing as her wind gusts, but with iron lightning instead.
                  • iron-lightning sword; creates a long sword with iron lightning that can be used to fight with
                  • iron-lightning island; creates an entire sky island of iron lightning; she could use her clima-tact to launch this island at opponents
                  • iron-lightning tornado; creates a tornado of iron lightning. Imagine a regular tornado, then image what would happen if the air inside that tornado was as hard as lightning and shot out electricity

                    WHY THE STRAWHAT GRAND FLEET WILL BE THE GREATEST

                    6963a0ad648ba3724d430c2229b11f86

                    I would first like to state that there are a few things that make the StrawHat Grand Fleet different then most fleets we’ve seen so far

                    1- They don’t stay together the entire time, each division of Luffy’s fleet travels the New World on their own adventures which will help them develop in different ways.

                    2- They all joined Luffy not out of fear but out of respect

                    3- A lot of the individual captains/commanders have their own goals/dreams, they might not be as big or important as the straw hats but they are dreams

                    1 Cavendish wants to be a star and a great pirate known all over the world
                    2 Bartholomeo wants to be of use to Luffy and help him and the crew in every way
                    3 Sai wants to raise the happo navy to greatness
                    4 Ideo wants to be a great fighter kinda like Ussop wants to be brave warrior
                    5 Hajrudin wants to rebuild the giant pirate crew
                    6 Leo and co want to help Ussop and Luffy as much as Bartolomeo
                    7 Orlumbus seems to love adventure like Luffy

                    Now their potential growth is the main point of this theory

                    But first i want to bring up one of my theories on kings haki and haki in general. Now i believe the reason why we have not seen a Marine or any strong member of a Yonko’s crew with king haki is because they serve under someone, kings do not serve others. Also ranking systems are in almost every crew or organization in One Piece except the Straw Hats. In this way the Straw Hats are all on equal ground with Luffy, they do not shy from making their opinion known like in most crews, Luffy has been shown to take their advice when making important decisions like with Ussop on Water 7 and Sanji here on Zou.
                    With this freedom i believe that the Straw Hats and fleet members are not limited in how strong their haki can be trained and developed. I believe that the fear to constantly please and obey Yonkos like Big Mom and Kadio limits the overall power of someones haki because haki is a form of willpower and fear weakens willpower. In saying that I do not believe Yonko crew members are weak just not as strong as there maximum potential. The Straw Hats and fleet do not serve Luffy like most fleets serve there captains, they assist Luffy in his quest to become pirate king, this change in mind set can cause many of the main fighters to develop new attacks and unlock higher levels of haki like with Ussop when unlocked his coO haki.

                    Sai could improve his dragon drill tech adding the power to his staff gain kings haki like Chinjao.
                    What if Hakuba is Cavendish’s personal haki demon like the Zoro has and he learned to control him?
                    Barto could learn to crate more then one barrier and shape them into weapons animals or other shapes..
                    Others could develop spiritual power up like Sanji’s fire, Brook’s ice, Fishman Karate and unknown tech

                    Please let me know what you think below
