Film Theory: The World of One Piece is BROKEN! 

A thing to note - Grand line doesn't lie at the equator. It crosses it at the 45° angle. The poles are in the middle of North and South Blues, not on the Red line.

Note: During time skip Nami landed on a skyisland.On it there are scientists that study the weather.They spread water among islands with water shortages.

I’m surprised that Matpat didn’t bring up the fact that the world of One Piece has been calculated to be 2.7 times the size of earth.

"If the world were real it'd be dangerous, disastrous, and ruin any attempt to better your life" It's pretty much exactly like that in the show too

I'm surprised that Matpat never touched on the fact that every Island in the Grand Line has its own individual magnetic field and climate surrounding it. I don't know much about that type on science but I thought for sure that it would have interesting implications if carried over to the real world.

A couple of things matt didnt mention: - one piece planet has 6 moons to effect the tide - the planet is huge, alabasta is the size of australia based on canon measurements, and theres still a vast amount of ocean around it with the calm belt not in sight

Something he failed to realize is that we literally do have calm belts in real life. They're called doldrums, and the reason you never see them talked about is because ships avoid them due to the absence of wind. They ALSO stretch around the equator.

Please re-do the analysis with consideration that the grandline is not over the equator but actually at an angle as mentioned by Law somewhere around chapter 1000. It would be super interesting to see if the world would be more livable at least climate-wise. Love your videos!!!

The four oceans being almost completely separated is even a plot point, Sanji’s dream is to find the All Blue, the one point in the world where they mix

You're forgetting a crucial detail, there, MatPat! It's true that the mountains in California cast a rain shadow over the regions to the east, but that region is almost entirely dry land. If the world of One Piece is 90% water, then most of the area affected by the 'rain shadow' will be ocean. Almost all rain that falls on land starts in the ocean. While the area won't be receiving moisture from the west, it will have its own ocean to contribute moisture to the air.

The live action version was amazing. Much better than what I initially expected.

they actually have water purifiers in episode 68 and 69 Nami says to Usopp "can you purify the water im going to take a shower"

"If the world of One Piece were real, it would be dangerous, disastrous, and it would and it would ruin basically any attempt to better your life" That's the One Piece we know and love.

I think something interesting to add to this is that water politics is a very real thing in one piece (Alabasta) where the access to water was as central plot point or the more recent raising of the water levels in both the more recent events in the manga or water 7 sinking

"No technology advancement " vegapunk : Am i a joke to you ?

In Episode 56, a fisherman tells Sanji that the currents from other seas bring fish from all seas to Loguetown in the East Blue, explaining why there are so many of a particularly rare species. So according to the show, all of the seas are connecting more than we think

A few corrections: 1. One Piece world's regional weather has a much more significant effect on the climate than global monsoons, for example, Little Garden is a tropical island, the one near it, Drum Island is a tundra, and Alabasta is a desert. 2. There are global deep water current systems explained in the Fish-man Island arc that connect the world's oceans other than the Reverse Mountain. One of the weirdest natural phenomena in the One Piece world is the fact that there is breathable air as far out as the moon, shown in Enel's (lightning god guy) coverage story.

I've always wanted mat to make a theory about Zoro's biteforce

I have a feeling most of the “errors” Mat finds has already been given in world explanations by either the manga or Oda himself.

I know it's unlikely but I really hope Mattpat does more one piece theories I absolutely love both film theory and one piece

A couple things: 1) The OP world is significantly larger than Earth, there's videos you can find where people have done the calcs (shout out Tekking101). 2) The Red Line & Grand Line intersect at a 45 degree angle (forming an "X" on the planet) as opposed to N-S then E-W. 3) There are powerful deep ocean currents in the OP world that are able to move water back and forth between the seas.

You know it’s a great day when matpat makes a one piece theory

Ma man predicted it as always ggs man

The problem with his theory is the scope of the mountains compared to the size of the world in OP. There are mountains near most coasts but obviously inland enough there are rampant winds hence why the bread basket of America is famous for tornados. Similarly, for OP, if the islands in the east blue are similarly far away, they wouldn't be affected by his theory as exemplified by the rain in Logue town

The rain shadow affect does not apply to islands. The moisture that is removed in the rain shadow affect comes from the ocean which they are all surrounded by. If it was all land on the other side of the redline it would apply but since it’s immediately more ocean it has no bearing. Also this over abundance of ocean would lead to regular rain storms which may be where most of these lands get their water from.

I truly hope there is more One Piece content coming from Film Theory! I screamed so loud when I got this notification! Been waiting for years for Matpat to talk about this amazing series

Matpat I love all your theory's but as someone who is a One Piece fan the extremely cold and snowy/the extremely hot and dry lands are exactly what we see in Drum Island and Alabasta! Plus I guess we just aren't going to talk about how big the One Piece world is with Big Mom being 28 ft tall and Oars that big red giant demon thing is about 208 ft tall...which means that the One Piece world is WAY bigger than ours...which means the water percentage is like 70 maybe even 60% water considering how big it is,the lands would also have to be big. I still love your theory's though this is not hate just me explaining some things hope it helps!

Later matpat, you will be missed by all

Most if not all points had been already answered either in the Manga or by Oda. Theres solutions already in place for all of that, the fresh water, the grand line and calm belts. And i dont want it to sound like im bashing the theorist team, i love the fact that you guys decided to do a theory on this. I just hope next time you let the theory cook a bit longer or collab with another channel that studies One Piece because it truly is a whole world of its own that takes a lot of time to fully grasp

Glad to see to guys tackling One Piece! It's literally a treasure trove of theories. Being a one piece fan myself I can tell you from experience that every week whenever a chapter drops it's always constant discussion on what might happen in the next chapters, what's the next arc is gonna be, literally a gold mine of theories here

just read chapter One Piece Chapter 1113. I think this theory might be correct

5:58 this explains the desert section in gta 5

I actually love this theory’s conclusion because there is an implication of old technology being far more advanced and the world being post apocalyptic in more recent chapters like the world somehow had some sudden shift and everything was forgotten

2:09 Matpat didnt need to jumpscare me like that

7:41 Basically a Horse Latitude named after the fact that Viking Discoverers used to Maroon thier Horses to lose weight to even row and move in those latitudes because there's no wind.

The equator isn’t at the grand line, this video is completely destroyed

ONE PIECE?! What an unexpected episode of Film Theory! Much love to the content!!❤

Surprised that matpat didn't talk about the fact that every island on the grandline has it's own magnetic field.

It could be argued that that was made by design, the world government wants to consolidate power and technology and with all the power/magic systems in One Piece they could have resorted to making it happen so the world would be like that. We also know that a character has a title of "continent puller", we don't know why and this could just be the reason.

i Appreciate your take on this sir.

On a note, you can see the different climates of the blues. The North Blue is known to be always cold, the South Blue is known to be tropical and East and West Blue are pretty diverse in the climate with normal seasons

Ive never been more heartbroken by matt patt he really use real world logic without taking account for the size or the way the world of one piece works😭

Definitely need a video on devil fruits, like... what are the chances you will come across one? And is there a way to figure out what type it is before you eat it?

I’ve been waiting for you to do this for 5 years .

7:00 there's a problem with the Rain Shadow you mentioned. All that ocean water the winds go over will rehydrate the air very rapidly. Only the closest islands will be affected.

His crew isn't looking for the one piece they just helping him pursue his dream to find it. They all have their own dream that they strive to achieve on the journey.

2:04 hello person here from after the LA came out. If was SO GOOD! I was pleasantly surprised to how good it was lol. It was a great adaptation, very happy

I’ve been waiting for this so long

I loved the points Matpat made in the video, but as a die hard One Piece can ima have to put in my two cents. Something he neglected to mention, the One Piece world is nearly 3 times larger than earth, so the effects mentioned in the video wouldn’t be as nearly as drastic as if they were to happen in the real world. I think Oda did perfect portrayed the actual struggles perfectly, the islands visited could easily be justified with logic.

Note: the rain shadow effect won't happen to every island since all the islands in one piece is almost surrounded by water, which means almost every island is getting moisture air and so all islands in one piece is lush green as shown in the series

Video Suggestion: Make a video about the Animated Series Total Drama!

Finally found it so glad you fone a video on one piece hope for more 🙏🙏🙏

Matpat doing a theory about a series that both the fan base and the author have put 25 years of thought into. This can only end so well.

I have a feeling 100% of this theory doesn't account for the fact that YOU CAN FIT 4 EARTHS INSIDE OF THE ONE PIECE PLANET! the place is huge and there are islands like Alabasta which, despite being a desert, ARE INSANELY HUGE!

Came back to this video just to say that I think another FMA theory would be amazing (may I suggest a theory about Xerxes, the town that got wiped out)

Finally, I’ve been waiting for this!

I hope there's a follow-up post/video addressing a lot of the holes in this video that so many others have already pointed out. I love Matpat and everyone on the theorist team for what they make, but this one definitely shouldve been left to cook for far longer before trying to theorize in such a well established fandom/theorizing scene 😅. Hopefully, if they make another One Piece video, they right these wrongs because i love them *and* this story so so much, i just want them to 'get along nicer,' in a sense.

I mean, considering that the first few islands that Luffy's group visits after crossing the Red Line are a barren, rocky desert region, a factory on barren rock filled with dangerous and experimental chemicals, and how it specifically states that many islands are ininhabitable directly east of the Red Line, I think the authors and producers actually did a great job portraying that specific struggle.

6:44 Shout out to the editor for using an image that nukes the whole "theory" 🤣

I didn't realise he was gon talk about the litteral world of one-piece

Is it just me or sometimes do you get sad when you only see a 10 min theory. It’s out of love, I love sitting here for almost a half hour and breaking down lore it’s the best part of the week ❤️😂

I would love to see a part 2 to this where Matpat cover how deep the ocean is for the Sea King to reach the size that they are.

i genuinely learned a lot from this video

I feel like MatPat just dived into this because it’s a popular franchise

Matpat you missed a crucial part of the one-piece world that the north, east ,west and south seas are called that way because they are in that direction and the redline doesn't divide the globe in north-south direction rather in a diagonal way from northeast to southwest and vice-versa for the grandline, while it might not make any difference for the theory (maybe) but makes a huge difference in how the weather might work as the heat distribution will change drastically meaning the east n west seas might not be as inhabitable as they seem and this is backed by the characters in the show itself ,for example when the map of the world is shown in the show. Also the size of the planet makes a big impact on everything else it has. I hope you see this and think about it and I hope to see the next videos to be a bit more accurate. And don't feel bad I actually loved the video just thought that I should point out this thing even though it might not be that big or cause an significant impact. Hope you have a great day and keep making videos on one-piece.

How did he not talk about the fact that each island in the grandLine comes equipped with its own totally isolated climate, complete with their own seasonal pattern that operates completely independent of the islands or even the sea around it?

Not even a Theory

I totaly would like to see more one piece theories like this one in this channel

Lets not forget that the islands on the grand line pretty much have their own climates. Drum Drum island is like the polar ice caps where water 7 is like a very nice vacation town and little garden is like stuck in the prehistoric age with the climate to match.

The researchers for this episode dropped the ball, as noted by everyone else in the comments. And there are entire continent sized islands of desert, Alabaster. But sure there are also floating islands once populated by an alien humanoids, and even with their technology, they’re practically an endangered species. So I guess the theory hold that the world it to hostile for anyone not from there to survive.

I watched the Live Action show, its amazing btw, and I thought how they have so much food all the time. The no drinkable water is also plausible because there is no one ever that drinks just a glass of water, only alcoholic beverages and tea and stuff. And I think Oda didn't think alot about the planets design so that he can add new places as the show goes on. Except maybe that its an X were in the middle of it is definetly the One Piece, X marks the spot. but there are two X so Idk

Super excited for this crossover video

As happy as I am that you guys finally did a One Piece theory, I wish you had more. It would be so interesting in seeing you trying to piece everything together. Maybe doing videos with prominent One Piece theorists if you happen to do more on One Piece

I agree that the Calm Belts would be devastating for the ecosystems all over the One Piece world, but I think you're forgetting one key factor when discussing the effect of the Red Line. When the sea winds coming in off the Pacific are stopped by the Cascade Mountains, it turns the other side of the Cascades into a massive desert because that area is a vast stretch of land with very little water of its own, therefore it can't sustain a normal cycle of evaporation and precipitation. However, in the case of the Red Line, the area where the rain shadow would be located is yet another vast ocean that covers half the planet, so that water would be able to evaporate normally and return to the surface as rain. (By the way, even if it DID work the way you described, it wouldn't affect EVERYTHING east of the Red Line; the rain shadow wouldn't extend all the way to where the Red Line crosses again so half of the planet would be barren no more than the rain shadow of the Cascade Mountains renders everything to their east inhospitable. Of course the area immediately to the east of the Cascades is desert, and its effect extend as far as the western parts of Texas and Oklahoma, but beyond that are very fertile and thriving plains and forests that reach almost all the way to the Atlantic. The rain shadow would only effect at most one-quarter of the area to the east of the Red Line, and this would not be exclusively in the East Blue, South Blue, and the Paradise half of the Grand Line; you're not thinking in three dimensions. at the other end of those three seas, we would find the prevailing east-blowing winds being stopped by the Red Line and unable to reach the North Blue, West Blue, and New World, so that area would also experience a rain shadow the same as the eastern end of the others, but this is all rendered moot, as I said, because there is plenty of water there for its own evaporation/precipitation cycle.) And I won't even go into how a degree of weather control has been figured out in the One Piece world as covered in the Alabasta Arc. As for the lack of fresh water, just think about this. People develop technologies that solve problems, with the biggest problems being the highest priority. Because the need for fresh water would have been a VERY large problem (probably the biggest problem in the One Piece world), it would have be the focus of many a scientist and inventor, so I have no doubt whatsoever that desalination technology has not only been developed, but is in fact commonplace and has been refined and streamlined far beyond what the real world has since invention is driven by need. Furthermore, because the need is so prevalent, I am sure that many people have developed desalination technology independent of each other and/or have built on the technology invented by others. In short, for such a common need, it wouldn't even be possible for the wealthy to hoard the desalination technology as someone else would just invent it on their own again and again until it is finally created by someone altruistic enough to share it with the whole world freely (and since we know for a fact that the One Piece world has been in its current state and occupied by "civilized" people with the same approximate technological level for AT LEAST the last 800 years, not to mention the Void Century and the higher technology they had then, it is entirely feasible for that to have happened by now). In other words, the only major climatological issue would be the Calm Belts, and depending on EXACTLY how far they reach, there could still be tropical waters beyond them that would allow for currents to spread warmer waters. I personally agree with the theory that the One Piece world is tilted on an axis that places the poles in the North and South Blue, respectively, meaning the equator, rather than following the Grand Line, would go through the middle of the East and West Blue while allowing the southern tips of the North Blue and the northern tips of the South Blue to extend well into the tropical regions. In essence, the Red line and the Grand Line would for a giant X. How much of the North and South Blue extend into tropical waters is still dependent upon the breadth of the Grand Line and the Calm Belts, but on MOST of the maps Oda has drawn in the series it doesn't seem SUPER wide, so I think it should work out. Sorry this ended up so long, but I just had to address some important holes in your theory.

I'm currently watching the introduction to Big Maama's Introduction, That's strikingly similar to Disney's 1940s and 1950s anime style when i saw the musical 😅

Got a science lesson in this, thank you Matt 😊

Matpat may have just accidentally explained part of why the oceans are the way the are because One Piece's World Government literally aims to limit technological advancements.

The researchers dropped the ball on this ep. While yes the one piece island world would be a problem for earth sized planet, the one piece world is actually much more massive meaning these “small” islands would have enough water

The world of One Piece has two different levels of islands, so the atmosphere must have many different humidity levels . I would assume that the sky islands would act like a heat and humidity dam .that means the weather fronts would just back up and eventually monsoons on the way word side . It's a fact happens every summer in Eastern Colorado.

1:22 my most favorite line mat pat has said 😂

HE USED THE 4 KIDS DUB 1:14 💀

Never did I expect to see a One Piece film theory. Please more, this opens up so much!

The one time I thought he couldn’t theory on one of my favorite things he comes up with a theory on my favorite show.

According to Vegapunk's last words in chapter 1,113, the One Piece world is literally sinking into the ocean. The special weapon used by the World Government against Lulusia raised the sea level by 1 meter globally. That's one out of 8 rebelling islands so the minimum rise is 8 meters. This rise in sea level only intensifies if more islands are destroyed. The gradual increase without destruction of islands still gets faster for unknown reasons. Maybe it's the phrase "the darkness will swallow light" due to the sunlight tree, Eve, being sealed in the Red Line. This might be related to the Great Flood that happened 900 years before the story. Or it maybe that the islands are literally sinking into the ocean. At Water 7, the scenario might be different due to the Aqua Laguna floods. Maybe the floods started due too Wano's walls dumping tons of rainwater into the ocean. The World Government's original plan might've been to seal the Sunlight tree, Eve, and to destroy the 5,000 year old tree of knowledge.

Some notes: 1. Something that breaks this further is that the one piece world has been calculated to be 84% the size of our sun, meaning gravity would be extremely strong 2. All islands would receive moisture from the surrounding bodies of water, unlike the region of the United Sates which is completely blocked by mountains 3. Definitely watch One Piece. In the beginning, the number of episodes is daunting, but at the end you'll wish there were twice as many episodes (it is still going by the way at a rate of an episode every week, sometimes every 2.

Interestingly, the first major arc in the Grand Line (the stuff actually just East of the Red Line) DO take place on extremely arid islands where food and rainwater are scarce. A huge drought is the central conflict of the Alabasta saga, the first main one in the area MatPat talks about here. It may be just a coincidence, but maybe Oda considered some of this as well. 🤔

Thank you for everything and making my childhood ❤😢

Matt, please make a film theory of what is the one piece treasure

One thing to point out is that most island are about a few days away from the the redline so they really wouldn't get the rain shadow affected. Plus each ocean has a different air and water current kind of rotating within there own ocean

I haven’t watched one piece, but this didn’t contain many spoilers, so the team did a great job, only shows you characters and tells you about locations

I mean the rain shadow effect shouldn't matter that much for islands considering they're surrounded by water. Hard for a planetwide mountain range to cut access to moisture when your island is surrounded by water. It would stop moisture from one half of the planet from getting to the other but it's not like the other side doesn't have water of its own.

I’ve always wanted a film theory about One Piece!

This is the sign for everyone who hasn't to watch One Piece. Watch it. Trust me. I was sceptical when I started, even dropped it twice, but after getting into it, it is EASILY my favorite piece of media (TV-shows, movies, books etc. included)

One Piece is my favorite piece of fiction of all time. I'm so happy that Matpat was able to cover it. If you haven't tried it I would DEFINITELY recommend it. If you feel its too long or anime isn't your thing the live action comes out next week

Wealth, fame, power all things can be given to us by game theory

this is the best two things that have finally collided.

Kinda surprised matpat did do more one piece theories. With all the lore and mysteries. He should have a years worth of theories

I would love to see more episodes like this talking about the worldbuilding of One Piece. The Worldbuilding is not only one of the most important and beloved parts about the show, but also it's much less heavy to cover the worldbuilding in small pieces rather than the overloaded lore that would be ipossible to catch up on. And as long as you use these theories to strengthen this sort of love for the show, I also don't think the chance of upsetting any fans would be that high.

FINALLY A ONE PIECE THEORY I’VE BEEN WAITING FOREVER

“They would be fighting over resources” Cook-cook fruit: ahem
