According to Clover the Ancient Kingdom was the enemy of the World Government. And it had ideals that possess a threat to the World Government. Even it’s name is considered a threat. The Gorosei ordered the to shot Clover before he could reveal its name. The only person who could possibly know it’s Robin. She had access to the same Poneglyph that Clover studied. If she wasn’t able to read it at that time or Clover had read other Poneglyphs at some point she will reveal its name. The World Government must have it since it’s possible to transport them.

The Ancient Kingdom knew that they couldn’t win the war. Therefore, in order to protect the history and their ideals. They created the Poneglyphs. Indestructible stones that contain information about the void century. They also contain information about the ancient weapons. Which seemed to have been created by the ancient kingdom. The Poneglyphs were created with the help of the Kozuki clan. Which suggests that they had allies.

I believe they had more than one ally. And the evidence that I have to support my theory. It’s the location of all the known Poneglyphs. All of them were hidden or inside territories. I believe that this allies were secret allies. The reason of why I believe this. It’s because the Kingdom of Alabasta had one, which was hidden. But, they were part of the 20 kingdoms that defeated the Ancient Kingdom. Why would they hide something that important from the World Government.

The other possible ally could be the Shandorians from Jaya. During the Void Century they fought against the 20 Kingdoms(World Government). The Kingdoms were seeking the Poneglyph that was in their territory. The kingdom fell but the 20 kingdoms didn’t took the Poneglyph with them. It could be possible that the Ancient Kingdom gave them the a Poneglyph. So that they could protect it.

It’s known that the Kozuki clan and the Minks have been allies for a long time. Therefore, they could have also been allies of the Ancient Kingdom. They even have a Road Poneglyph something extremely important. They been protecting it for a very long time. And it seems that not even the World Government knows about it.

The people from Fishman Island could also have been an ally. They have a really important Poneglyph. But, they don’t seem to be interested in it at all. The ancient kingdom could have chose that location to hide a Poneglyph. Because, it’s hard to get there. It could also e possible that Joy Boy was from the ancient kingdom. So he decided to leave a Poneglyph there.

I believe that the Ancient Kingdom had 8 secret allies. I believe this because there is a pattern of circles that appears in different important places. The pattern consists of 8 circles around 1 big circle. These circles can be found in the Kozuki clan’s symbol, Flags from the Kingdom of Alabasta, Franky’s clothes, and Skypiea. I only have identify 5 allies. It could be possible that the people from Birka were also allies. If not perhaps allies of the World Government or a neutral nation.

Someone said that it’s possible that the symbol represents the 8 moons from One Piece. And that it could be the Flag of the ancient kingdom. So the allies could be less or more than 8.

I believe that there will be an underground city in One Piece. Which will have enormous aquifers. If there’s one in the future. It could be possible that they could have another Poneglyph or at least had been an ally of the Ancient Kingdom. Whichever, the case maybe the circles are definitely a foreshadowing of something important.
I hope you liked my theory.

Theory by D Rayo

What makes the Gura Gura no Mi so feared and the strongest Paramecia?


The point of this dissection is to break down the Gura Gura no Mi, and what makes it so infamous, and What it’s prior users may have accomplished…

The Gura Gura no Mi has been said to be the strongest Paramecia, and is widely feared for its world ending capabilities….

“It may very well be us that meet our end here today… Because that man… HOLDS THE POWER TO DESTROY THE VERY WORLD!!!” -Sen Goku

Vice Admiral Tsuru said stated that, even if she retreated to the ends of the ocean, there would be no safe place left in the world for her to go when faced with the power of the Gura Gura no Mi.

What makes it so infamous?

Aren’t their other DF with potential world ending abilities?

A few potential that come to mind are;
Fujitora…Historically speaking, it wasn’t that big of a meteor that destroyed all life on this planet before…

If Kizaru can create or become a literal sun, or could make sun flairs, or change his spectrum of light to a more dangerous one, he could cause some issues..
A literal Black Hole… Nuff said..

Even someone like Caesar Clown could poisen, or mutate the atmosphere..

Lets not forget if Buggy manages to split himself past a molecular level, he would end the known world…

So if other fruits are potentially world ending, even other Paramecia… Why Does the Tremor fruit get the top spot?

Maybe it’s not strength, but fear… Notice how it’s mostly the WG that fears or reference the fruit as world ending?

Before I get more into my theory on prior users feats. Let’s see some of what we already know the fruit Can accomplish.
Probably the most feared and one if the strongest powers is the ability to create Tsunamis… In an Oceanic world, that ability is absolutely TERRIFYING…

The user can grab and shake the air or atmosphere and ocean itself!

The user can also send out shockwaves, and imbue his body parts with Quake bubbles

OK its fair to say this is one powerful fruit… But is it the Fruit or the user who makes it infamous?

Part of why the Fruit is so far been intimidating, is it’s been in the world’s strongest man’s hands, and BB both Yonko… Had someone like Usopp, or Foxy eaten the fruit, it may have seemed underutilized, or weaker… But what if the tremor fruit had an even stronger user before BB, and WB?

What if the Gura Gura no Mi falls into the same category as the Ope ope no mi, or the Yomi Yomi no Mi? Meaning the users prior lifes skills effect the abilities of the consumed fruit. The Ope ope no mi is best used by a doctor, the Yomi Yomi no Mi is enhanced by Brook’s Musical capabilities..

Wouldn’t it make sense that the Gura no mi, or Tremor fruit would be stronger in a geologist, or better yet a seismologists hands? Before we go further a quick dumb lesson on earth quakes and what they create…

Earthquakes caused by shifting plate tectonics happen basically three ways, and have 4 separate effects depending on location, and materials involved…

Either the plates rub as they slide causing massive earthquakes..

The plates separate creating a void, or chasm, like this

If this is done in the ocean it will create whirl pools…

Two plates colliding and one rolling over the other, this in the ocean creates Tsunami

And finally…

Two plates colliding and bursting upwards..

this very process formed the Himalayan Mountains

A measly little Range that towers 29,000 feet and spans 1,500 miles…

Kinda reminds me of something in One Piece… Something that the WG controls and uses, to keep a monopoly on the world, and provides a strategic advantage…thats right I’m talking about the one and only…


This was an idea that @Hithere made me think of, when he theorized that One Piece was in fact the destruction of reverse mountain, and the connection if all blue… So TY…

But what if the Red Line, the giant world sized equatorial mountain, that the WG controls, and uses to house its holy land… The same red line used to segregate the four Blues and the Grand line from each other… Was created by the WG using a Seismologist and the Gura Gura no mi?

This would explain why the WG fears it and labels it works ending, not because it can kill all life on this planet, but that it could UNDO the Red Line and free the Ocean’s from the WG…

Simply put the Gura Gura no mi could end the World, Government.

What do you think?

*Theory by Portgas D. Xatch


In the end Luffy should give the straw hat back to Shanks because it was a promise. But some of the Supernovae have a plan to kill Shanks, so probably Shanks will die before the end of the story.
So how will Luffy give back the hat? I think after having found the One Piece Luffy is going to travel a few decades back in time, for a yet unknown reason. So Luffy will give the straw hat to young Shanks.
Will Luffy meet Roger? No, Monkey D. Luffy will change his name to Gol D. Roger and become the pirate king once again. So Gold Roger is actually Luffy himself after having aged a few decades.
In the past Roger just appears through time travel and the straw hat doesn’t have a origin nor an end, it would be eternal, keeping on getting passed on between Shanks and Luffy/Roger forever.
Many of the events would have to be fated for the story to stay consistent, as Luffy/Roger said when he met rayleigh “It was a fated meeting”:

Roger already knew Rayleigh but Rayleigh met Roger for the first time. If you travel back in time everything has already been determined including your decisions, impossible to change the past due to fate.
I think the incurable disease Roger had is due to a rule which doesn’t allow the same person to exist twice, so he was destined to die before he gets born again. This would also explain why couldn’t travel back to save Ace. Because Luffy was already present at Ace’s execution and he’s not allowed to exist twice.
It also explains of course why young Roger looks very similar to Luffy and why many older people see Roger in Luffy. I believe long time ago Roger was drunk and told this bartender that he came from the future, and now the old bartender recognized him:

Now we also know why Red Hair Shanks risked his life to save Luffy: it’s because he knew the time travel story and he recognized that this boy could be his former captain. He even told Rayleigh about it:

It also explains why Gol D. Roger said that he already knows that Garp will take care of Ace: because he alredy saw it himself when he was kid Luffy.

The reason Garp actually takes care of Ace is because Ace is the son of Roger who is Luffy who is the son of Dragon who is the son of Garp. So Ace is Garps great-grand-son. When Sakazuki killed Ace Garps line of descendants got exterminated, which is why he lost control in that moment:

Things we can expect from Raftel

Raftel is the island at the end of the Grand Line which supposedly holds the treasure One Piece. This theory is about things we can expect in Raftel arc

Design of Raftel 
Raftel is formed by using two words: Raft meaning something used as a boator floating platform and El which is a nickname for elevated railway system.

In Water 7 we see a panel were iceburg mentions to franky that he intends to make whole Water 7 float like a ship

Similar kinda thing was done in Thriller Bark where the whole island was turned into a ship , I believe same thing was done in case of Raftel which is why it’s a floating island

We may also find railway tracks similar to Skypiea and Water 7 to keep the island afloat or something like that

The Mysterious Egg 
Many of you aware that Gol D Roger had a mysterious egg on his ship for those who don’t know here it is

Monkey D Luffy’s character was inspired from Son Goku from Dragonball series as mentioned Oda himself, Son Goku who in turn was inspired from Sun Wukong

Sun Wukong, also known as the Monkey King, is a mythological figure who features in a body of legends, which can be traced back to the period of the Song dynasty. He appears as a main character in the 16th century Chinese classical novel Journey to the West.

According to the legend, Sun Wukong is born from a magic stone that sits atop the Mountain of Flowers and Fruit. The stone develops a magic womb, which bursts open one day to produce a stone egg about the size of a ball.When wind blows on the egg, it turns into a stone monkey that can already crawl and walk.
I believe this mysterious egg maybe inspired from legends of Sun Wukong of course it’s a chance that Roger may have left the egg for his successor which leads us to next point

Song of the Island 

Tuatha Dé Danann many of u might have heard of it in any theories let’s have a quick summary

The Tuath(a) Dé Danann usually translated as “people(s)/tribe(s) of the goddess Danu”, also known by the earlier name Tuath Dé (“tribe of the gods”),are a supernatural race in Irish mythology. They represented as a potential suspects for clan of D by many theorists while that may or may not be the case in this theory let’s take a look at 1 of 4 magical treasures of the mythology which is

The Lia Fáil ( meaning Stone of Destiny) is a stone at the Inauguration Mound (Irish: an Forrad) on the Hill of Tara in County Meath, Ireland, which served as the coronation stone for the High Kings of Ireland. It is also known as the Coronation Stone of TaraIn legend, all of the kings of Ireland were crowned on the stone up to Muirchertach mac Ercae c. AD 500.

The Lia Fáil was thought to be magical: when the rightful High King of Ireland put his feet on it, the stone was said to roar in joy.The stone is also credited with the power to rejuvenate the king and also to endow him with a long reign.

I always wondered how will whole world know if Luffy becomes pirate king or how they knew when Roger became the pirate king it’s not that they called a press conference to announce it, according to Irish legend when true king touch’s the lia fail it roars in joy as song of island

This was actually foreshadowed in Skypiea arc when Luffy rang the bell and. The Island and below in jaya also it was heard the ring of bell .plus this stone will prove that Luffy is one true pirate king after Roger

The Treasure of Gol D Roger 

At execution platform Roger said ” if you want my treasure then take it I left it there ”

Most people assume that treasure which Roger obtained was originally from Raftel, while this partially right it’s wrong also as even before Roger reached Raftel he was a big time pirate alongside Whitebeard and Shikki etc.. he should have his own treasure comparable to them and I believe he left it in Raftel along with the One Piece for his successor in his ship the Oro Jackson which might a reference to Lost Treasure OF THE SAN MIGUEL

The San Miguel, a Nao class vessel, has yet to be found and is believed to have separated from the fleet the day before the storm struck. Carracks are lighter than Galleons and were often used to carry treasure as they stood a greater chance of outrunning storms and privateers. The objective, after all, was to get the treasure home. This could mean that the San Miguel is actually one of the richest treasure ships yet to be found.

Hall Of Fame 
Cemetery and grave are not a rare sight in One Piece, we had seen them in:

-East blue – Bellmere’s grave [arlong park]

-Grandline(1st half ) – Rumbar Pirates grave [thriller bark]

-And New World – Whitebeard and Ace

Hence I believe that Raftel final stop of grandline has also the grave of Joy Boy and his allies/nakamas and there story written on Poneglyph henceforth giving Robin the Rio Poneglyph and data of what happened in Void Century and so called secret of world which Roger pirates found

*Theory by Dave

Fujitora and his Sword

What if it’s not Fujitora who ate the devil fruit but instead it’s the sword of Fujitora who has the DF’s power.
Now we have seen many occasions where the objects are shown as DF users like Spandam’s sword which somehow absorbed a Devil Fruit, Zou Zou no Mi.

Now whenever this ‘objects with DF’s power’ is shown , it is mostly not that powerful and doesn’t have much of an impact …so it is possible that Oda might show us the true terror of mingling Objects and Devil Fruits.
And one of the name of Fujitora’s techniques is Gravity Blade, blade being the sword. Hell, Fujitora’s sword doesn’t even look like it can do much damage but still he uses and keeps it.When Luffy asked Fujitora the question about his DF, he didn’t answer….and more like, it looked like as if Fujitora was grinning and saying ,”Dude , I have no DF’s power . It’s my sword who got it .”
Zoro will fight Fujitora in the future , and a sword with a DF’s power would be a new and a nice opponent to him.

*Theory by Heavenly666Demon


The Yonko are limited to sharing the New World. That is pretty much a fact since no territory outside of the New World belongs to any one of them. Know that they could easily get past the calm belt like Rayleigh (even Krieg did it with a bit of luck). Also, I bet they have the money and influence to buy seastone coated ships like the Marines have and get across that way. So why are they stuck sharing the New World, a tiny strip of the ocean that is unsafe and chaotic?

In addition, the WG seems to ignore their crimes. Marineford was about Ace, and not Whitebeard. If the WG wanted Whitebeard gone, they could have targeted any one of his crew members; Whitebeard would have come charging in regardless. But only Ace was worth the fight. It’s already been explained that it’s because of the Pirate King’s blood. Still… isn’t it interesting that the WG cared more about stopping Ace than a Yonko?

Look at Big Mom, Whole Cake Island is no secret. If the WG wanted, they could combine their forces and take her out at any time. Contrast that to the Revolutionaries that had to have their base hidden on a legendary island for fear of being attacked. I don’t believe that the Revolutionaries are any weaker than a Yonko, rather they are attempting something none of the Yonko have done. Take territory outside of the New World. The Yonko can get away with a lot, but not this one thing. They must be contained to the New World or risk starting a war with the government and having to find a legendary island to hide on.

So I got to thinking, why? Why are the Yonko given a, relative, free pass? Sure, if they combined forces they would be a gigantic threat, but individually they aren’t. My guess is that the WG wants them for something; they serve a purpose. When Whitebeard fell, the Gorosei had no interest in preventing the rise of another Yonko, but rather wondered who it would be that takes the title.

So let’s think logically for a second, what benefit does the Yonko system provide the WG? Deadlock. They are all deadlocked against each other, incapable of growing or moving anymore in such a small space. If one gets too strong, then the Marines can intervene and weaken them back to normal. If one of them attempts to take on the government directly or oversteps its bounds within the New World then its asking for war and we already saw the likely outcome at Marineford. Without Shanks stepping in, nearly everyone of those pirates, without a Sub like Law, would have been captured or found dead.

This deadlock serves a purpose, to prevent any one of them from reaching Raftel. Raftel, the Pirate King, Ace… The World Government formed 800 years ago with one purpose, to destroy the ancient kingdom. It then spent 800 years destroying its name and history. Its purpose was never to rule the world or to establish justice. Rather, those are simply fronts like the Marines are a front to the public as mentioned in the meeting between Akainu and the Gorosei. The Ancient Kingdom is the true enemy of the WG, not the Yonko or Pirates. The balance of powers is therefore not some mathematical equation to determine who is stronger but rather a careful balance implemented by the WG to prevent anybody from reaching Raftel.

As an example, think back to Shiki vs Roger. If Shiki were to have been apprehended then he never would have been able to attack Roger. Also, the Marines would have been weakened as a result. The WG cares more about stopping individuals from reaching Raftel than it does about preventing the crimes of a pirate like Shiki. This same concept can be applied to the Shichibukai. Their crimes are pardoned so as to prevent rookie pirates from advancing into the New World. Yonko are given a free pass so long as they stay within the New World facing off against each other.

Hope you liked my theory and thanks for reading.

Kinemon’s Foxfire Style

Kinemon’s Foxfire style has 2 main points. First, it allows him to cut anything with searing fire. Second, it allows him to slice apart fire itself

So if it really is a sword technique, the question is where did he learn it? Well i think the creator of this sword technique are the Kozuki family. Yup, I think the one who taught the Foxfire Style to Kinemon is Kozuki Oden. However, i don’t think that Foxfire is the original name of this technique, i think Kinemon just decided to call it “Foxfire” because that is what people calls him.

Kozuki, the Fire Clan

So why do i think that the Kozuki family are the creator of this fire sword technique? Remember, the Kozuki clan are the ones who made the poneglyph. But how did they made the poneglyph’s which is said to be indestructible? How did they shape it into a perfect geometrical shape? Just writing in this indestructible stone is already astonishing. Well i think for them to make it, the Kozuki clan must’ve an excellent cutting skills. However an ordinary cutting skills won’t work in this stone, this is where they used their Fire Sword technique or to be more accurate, let’s call it the Fire Cutting Technique. In addition with this technique, i also think that they are using some advanced tools to create the poneglyph (Remember the AK is mentioned to have an advanced technology).

Now i wanna talk about how exactly does this sword technique can generate fire. I actually read 2 popular ideas that will fit with this theory. First is by friction, the same concept as Luffy’s Red Hawk. Second is because of the composition of his sword. But i want to add another idea, I’m thinking that maybe the ability to generate fire is a special ability of the Kozuki family similar to the Mink’s electro and Kinemon actually has a Kozuki blood running in his body. Maybe that is what made the Kozuki family special. Maybe that is why the Kozuki family is very close to the Minks even before the void century. Either way, it will still connect to my theory that the Fire Sword Technique originate from the Kozuki Family.

Clues and Forshadowing

Here are some clues and foreshadowing that may prove that the Kozuki Family is associated with fire.

1. Remember this flashback of Momonosuke, when Kaido attacked Wano.

Look at the panel that says “Light the Fires”. In the anime it says “Ready the flame arrows”, you can also see that the area is already surrounded with fire. This means that they are using fire enhanced attacks to attack the enemy.

2. Look at this colorspread which i think is a foreshadowing about Wano.

You can see Momonosuke and his retainers, the Strawhats wearing a Japanese clothing and in the middle is Luffy that looks like a Japanese god, A fire god. And did you know that in some mythology fire gods are associated with different kinds of crafts like metalworking, sculpture, blacksmithing and… stonemasonry.

3. Kozuki clan’s crest

Up until know, the meaning of the Kozuki clan’s symbol is still a mystery but i think Oda already gave us a hint about what it is.

– First are the orbs. It has been hinted with the shirt that Franky is wearing in the Zou arc.

Which clearly looks like a sun and sun is of course associated with fire. Also remember, Wano is based on Japan and Japan is also called The Land of the Rising Sun.

– Second is the bird. Since the orbs symbolizes the sun, the only bird that associated with sun and fire is the Phoenix which been hinted through Marco.

Another thing, I’ve been thinking the possibility that Marco’s phoenix df actually came from Wano. Have you ever wonder why Nekomamushi has confidence that Marco may help them. I know that they boarded WB’s ship but the thing is, Nekomamushi specifically mentioned Marco and not the the whole WB pirates. This made me think that maybe Marco has a deeper connection to the Kozuki clan. So what if… Kozuki Oden saved Marco in the past? Remember that the Phoenix df has the ability to regenerate and heal wounds. Maybe Oden found Marco in a near death situation and decided to give him the phoenix df.

Sun and Moon Connection 

As i mentioned above, i believe that the Kozuki family is associated with sun. But now i wanna talk about the Minks. There’s a popular theory that Full Moon has effects to the Minks (I don’t know who is the originator of this theory though but big credits to him).
With the Kozuki family having a connection with the sun and the Minks with the moon, this brought me to a Japanese mythology about the Sun and Moon gods.

Amaterasu, Tsukuyomi and Susanoo

Amaterasu is the Japanese god of sun, Tsukuyomi is the god of moon and Susanoo is the god of storms. They were born when Izanagi was purifying himself after entering Yomi. Amaterasu was born when Izanagi washed out his left, Tsukuyomi was born when Izanagi washed out his right eye and Susanoo from the washing of the nose.

So where i am going with this?

Amaterasu represents the Kozuki family, Tsukuyomi represents the Minks and Susanoo represents one of Kaido’s Calamity since storm is a calamity or maybe.. it represents Kaido himself. Another interesting is that in Japanese mythology, it says that Amaterasu and Susanoo had a conflict and Amaterasu decided to hide in a cave. This is possible reference to Momonosuke hiding from Kaido.
Now to end this theory, i want to show you a what think is a foreshadowing about Wano. That is through Big Mom and her 3 main homies.

-Napoleon the sword forshadows the samurai of Wano
-Zeus the thunder forshadows the Minks and their electro
-Prometheus the sun forshadows the Kozuki family and the fire technique.

That’s all with this theory, hope you enjoyed it

*Theory by jinz


Urouge is a pirate who hails from a sky island and is the captain of the Fallen Monk Pirates. He is one of twelve pirates who are referred to as “The Worst Generation”
Urouge’s name was derived from that of real-life 16th century Barbary pirateOruç Reis.

And his epithet “mad monk” is derived from 
Ji Gong 

the guy even has a movie after him

The Mad Monk -Ji Gong (濟公, pinyin: Jì Gōng; The Mad Monk in English) is a 1993 Hong Kong comedy film

Birka was a sky island far to the southeast from Skypiea. It is the birthplace of Enel and his followers.

Enough of info, now let’s jump into theory. 6 years pior to current storyline Enel and his followers destroyed the homeland called Birka

Birka name is derived from ancient city of moon and there were 3 races of winged people

After their arrival the 1st island they inhabited was Birka sky island. At some point in history, the three races became separated from each other and fell into the individual races. The Birkans settled on a Sky Island apparently named after their former home, Birka. They also appeared to “forget” their origins, although the moon, known to them as the “Fairy Vearth” remained a folk tale amongst their people, believing it to be a place of dreams.

I believe that Urogue was the God of Birka, now hold your horses, God doesn’t mean that he was almighty and powerful as we have seen Gan Fall God of Skypeia, an old man with no powers

Why Urouge was from Birka?
1.Look at his wings its similar ones Enel’s priests had

He dresses in similar robes to Divine Soldiers underneath the khaki robes he wears (which is also worn by the rest of his crew), which includes the white full-bodied garment with severed sleeves

2. Their name, Fallen Monk Pirates
Enel tried to destroy the Skypeia as people living in the sky is unnatural, so as God it is his job to keep the natural order. So we can assume he destroyed his homeland for same reasons ,and monks who survived the fall or escaped the island are Urouge and his followers hence named fallen monks pirates
Notice as divine soldiers and maidens with him and they follow him as their leader same as Gan Fall

3.His fear for lighting -After the war at Marineford, he and his crew go to the New World. They followed their Log Pose to a dark and stormy island that was spewing lightning, with no way to have a ship docking there
the raijin island

4. As captain of White Berets he said some fought Enel and and his followers but were unsuccessful they maybe fallen monk pirates

Scenario 2 :
This is short one, but one of possibilities is inspired by destruction real Birka

After having consistently described Birka as an existing city, Scholia 138 of IV 29 describes Birka’s sudden demise. Talking about Adalvard the Younger, the bishop of Sigtuna and later that of Skara, Adam or a later copyist has written:

“During his journey he seized the opportunity to make a detour to Birka, which is now reduced to loneliness so that one can hardly find vestiges of the city; therefore impossible to come upon the tomb of the holy Archbishop Unni.” (Scholia 138)
The remark does not make it clear if Adalvard found the city destroyed or if that had happened after his visit and the later remark was just to warn the future pilgrims not to go there anymore in vain. As Adalvard was back in Bremen already by 1069 and is mentioned as one of Adam’s sources of information, it would have been expected that word about Birka’s destruction had reached also Adam before he published his work half a decade later.

Urouge and his followers returned home only to find their home wiped out without a trace and hence left for blue sea, i find this unlikely but worthy enough to mention as inspired by real events is one of Oda’s thing

Urouge’s future role 
I believe that winged races (shandia,skypeia and birka) were once allied with Ancient Kingdom
For now Luffy saved both shandia and skypeians from Enel and his followers and took payback for birka ,which Urouge doesn’t know, it’s very similar to Laboon and Brook, Luffy stopped Laboon from damaging himself later, Brook was thankful for that and at some point of time Urouge will ally himself with Luffy similar to shandia and skypeia people
Side note: Urouge might meet Strawhats at Elbaf as the land ruled by God theme is similar to Skypeia

*Theory by Dave


Sanji and Zoro will be getting devil fruits soon

Oda has been foreshadowing these fruits for these powerhouses since Water 7. Zoro was shown to have a slight power of Asura in the fight against Kaku, obviously he didn’t become Asura because his current body doesn’t allow for the full transformation. Sanji in his fight against Jabra unleashed his Diable Jambe, obviously a nod to the devil, also known as Diablo in hispanic culture. Same thing goes, his body could not handle the immense power of Diablo. Oda is known to foreshadow very early in one piece so I believe that these two will be receiving devil fruits, probably during Wano.
The names of these fruits will be Asura Asura no mi and the Diablo Diablo no mi. They will mythical Zoan types. Both of these fruits allowing the users to completely transform into the demons. Their base powers will obviously both be upgraded since they will awaken their fruits full potential during Wano, since they have experience unlocking these powers without the fruit, along with being given immortality. Asura’s are known to have superhuman abilities, along with the extra limbs that Zoro is given in his initial activation of his Asura ability, so there will not be any special abilities besides the increased physical capabilities. There are many theories out there about Zoros eye, with the consumption of the Asura Asura no mi opening his eye will open a gate to the underworld where Zoros opponent will be sent only after they have been weakened a significant amount. Sanji will Receive a buff as well with the consumption of the Diablo Diablo no mi, his physical capabilities will not change as much as Zoro but he will have full control of fire. He will also be able to summon demons from the depths of hell and command them. Every step Sanji takes will melt everything that has the misfortune to touch his feet. (Fun fact: Sanji can also cook faster with this devil fruit)
It is Necessary that these two consume a devil fruit in order to compete in the New World. Luffy is far beyond their skill with his Gear 4th, especially when Gear 5th is on its way as is. Even with that Luffy cannot hope to be King of The Pirates without a solid foundation in his crew to help him fight the Yonko.

Devil Fruits Limitation

This time I want to discuss the universal limitation for Devil Fruit.

As we all know that Devil Fruit users are divided into 3 : Zoan, Paramecia, and Logia. And I speculate that each Devil Fruit has its “limitation” to avoid being overpowered.

I speculate this emphasized on the canonical Devil Fruit; Bara-Bara no Mi. It was once stated that the unit for Buggy’s power is Bara-Bara; and his limitations is 200 Bara-Bara. So within the radius where his feet stand, Buggy can separate and levitate his limbs as he wishes, but outside that radius, his power will be useless.

Previously I speculate about Robin’s Hana-Hana limitations. For those who hasn’t read my speculation on Robin, I will make it simple here. Robin can bloom her limbs anywhere as many as she wishes on any surface; and even recently she can bloom thousands of limbs and even her entire body. But once Oda stated that Robin could bloom“200 Hana Hana”.

Because it was pre timeskip, fans speculate that Robin could sprout max 200 Hana-Hana, and since now Robin can bloom thousands of limbs & her entire body, the 200 Hana Hana doesn’t apply anymore. Actually it still does apply. That’s the maximum radius around Robin’s body where she can bloom her body.

Robin’s height is 188 cm, so approximately her arm’s length is 100 cm/1 meter. 100 x 200 = 20.000. Robin’s Hana Hana can only be effective within 20.000 centimeters or 20 kilometers. Approximately her power will activate 10 kilometers in ball-shaped radius with her real body as the central. So although Robin knows exactly how Alabasta is, she cannot bloom her limbs on Alabasta (as she is currently heading to Wanokuni) because Alabasta is not within her reach of power to be effective.

So I speculate that Luffy as well has 200 Gomu-Gomu where that is the max length he can stretch his body. Luffy can stretch 200 Gomu Gomu away before he can probably feel pain on his outstretched body. To count exactly the same with Robin, Luffy’s 200 Gomu-Gomu is 10 kilometer long.

This 200 Gomu-Gomu will be a reason for Luffy’s final Gear where he can probably expand his entire body into gigantic shape. Note that this final Gear is different with Luffy’s Gear 3rd where in Gear 3rd Luffy could only expand selected body part. Luffy’s final Gear form is probably Great Ape form. As his namesake, Monkey. D. Luffy, probably Luffy’s awakening / final Gear is the Great Ape. It’s also as the dedication to Akira Toriyama as Oda himself is a fan of Dragon Ball.

So from Buggy, Robin, and Luffy, I speculate that Paramecia type unit is 200, added with their Devil Fruit power. For example : Hancock’s Mero Mero no Mi is 200 Mero Mero. Probably Hancock’s Mero Mero will be effective within the radius where people need to see her beauty for her to petrify the object. Or Brook’s Yomi-Yomi no Mi, where he can separate his soul only within 200 Yomi Yomi before he needs his soul to be back to his body.

The unit limitation also applies to non canonical Devil Fruit. For example from One Piece Film: Gold. Gild Tesoro’s Goru-Goru no Mi is 200 Goru-Goru. His ship is 10 kilometers long. That’s where his power can be activated because it’s within his radius. This also applies to Baccarat’s Raki-Raki no Mi; where she probably can absorb luck from 200 people before it is overlimited and could probably backfired.

Some Paramecia has bigger range of the unit; for example Viola’s Giro-Giro or Fujitora’s unknown Devil Fruit. Viola’s Senrigan is 4000 kilometers away, but it’s possible that it’s within her 200 Giro Giro. So she can’t use her power above 4000 kilometers/200 Giro-Giro. Fujitora’s unknown Devil Fruit which control Gravity is probably 200 as well as he needs a certain distance to summon a meteor to fall impact on land.

Now that’s for the Paramecia class. How about Zoan and Logia type? Logia type is indeed the strongest Devil Fruit as it’s the power of nature itself. But of course the power of nature has its limitation. Probably for Logias, they limit is 300. Smoker’s smoke body can be effective within 300 Moku Moku. Sabo / Ace Mera-Mera can burn anything maximum 300 Mera-Mera. Even Akainu’s Magu-Magu; especially Ryusei Kazan; can only be activated within his radius. Although Akainu launches his Magma fists to the air, it can be assured that his fists will fall around his 300 Magu Magu range.

Another possibility is that for Logia users, instead of range, their unit is for how many nature force they can produce / control within their area. Logia users can control nature force of their own to amplify themselves, but of course they have their own limitations as well. So it’s possible that Logia users 300 unit is the maximum element their body can produce / control. This is emphasized on Punk Hazard where the island is complete opposite from each other; and using the full reach of their limit will permanently leave a whole area to be affected with their power.

The maximum production of Logia users can also make them become vulnerable to attacks, although some elements maybe superior to the other. Kuzan and Sakazuki are vulnerable to each other, although in the end Sakazuki is superior to Kuzan’s Hie Hie no Mi that makes Kuzan lost one of his leg; but Kuzan managed to inflict damage to Sakazuki as well. So it’s possible that both Sakazuki & Kuzan used 300 Magu Magu and 300 Hie Hie in their 10 days fight to affect the whole area and left huge damage on both side.

So for Logia, the limitation is another “weakness” to make Logia user not to be overpowered. So probably the Logia user can control the whole island with their element, but once again the limitation is not the range / radius; but the production of elemental nature the user can produce before they overexert themselves and become vulnerable even with common attacks.

As Zoan is the “weakest” Devil Fruit. So probably Zoan Devil Fruit user will have 100 as their unit. Or it can be possible that Zoan is the only Devil Fruit which has no unit as their limitations.
