 Hello and welcome to the Grand Line Review, your source for everything one piece. And today it's time to take our exploration of this wonderful series back into the realm of the unknown and examine some more unsolved mysteries. Now before we get into things proper I would like to highlight the fact that this video is a sequel and I do recommend you watch the first video which covers some of the most enduring unsolved mysteries in the series. So that you know if you don't see some very obvious candidates on this list today then they're probably in that first video, the link to which is in the description below. So back to what we have today I'd also like to stress that this is in no way a theory video. My intentions here are not to solve these mysteries but simply to present them. As a result I'm not really going to go into any depth regarding fan explanations or theories and of course just to state the obvious, to qualify as a mystery on this healisty the subject in question needs only not to have a current official explanation. And furthermore all mysteries on this list must be canon because of reasons. But with that out of the way let's begin. Coming to another bout of the top five greatest unsolved mysteries in one piece. Number five. Zorro's Eye. So at the time of this recording we're sitting at almost ten years after Zorro's post time skip design was first revealed to us which was probably one of the least radical changes of any of the Straw Hat's aesthetics but with one important exception being his left eye which was now scarred and has not been seen in a state of openage in the New World era. Now the most mundane explanation for this change is simply that it was a scar gained through his training with the world's greatest swordsman Dracul Mihawk which makes easy easy sense but admittedly it doesn't make for a lot of fun in regards to speculation so instead we'll move on to the idea of mask theory which if you're not aware is the idea that a prominent character will only wear a mask if they have something to reveal which will almost always be the case think of characters like Duval, Killer, King Riku etc and this theory can extend beyond physical masks to include any part of the body that is hidden such as Zorro's eye and given that he is such a prominent character it is fair to think this eye is being concealed for a decent story reason rather than just an aesthetic choice. Then again to be fair a lot of people also thought that about Sanji's eye and when we saw it post timescape it was well it was an eye but there is some evidence to support Zorro being a bit different which is that other prime swordsmen within the One Piece world do carry this common trait and I'm specifically speaking of Ray Lee who has the exact same scar on his right eye as well as Rima who appears to have kept his left eye quite concealed or somewhat concealed. Now there are a huge range of theories out there as to why this is such as Zorro's eye being a vessel for some sort of demon that inhabits the cursed sword the Sanda Kitetsu and that this is a condition that any cursed blade wielders must meet to make the most of the sword but whatever it may be it's undeniably intriguing and until a straight-out answer is ascertained it will continue to be an enduring mystery in the series. Number four, Crocodile's Secret. Now here's a bit of a fun one that originated from the Impel Downock rather casually actually during a verbal exchange between the one and only Sir Crocodile and the other one and only Emporio Evenkov and what it boils down to is basically a light threat to keep Crocodile in line because apparently Evenkov knew Crocodile when he was a rookie pirate and as a result is privy to one of his secrets. And after this chapter came out speculation ran wild about what this could possibly be with many prominent theories going on to state that perhaps Crocodile used to be a woman and had Evenkov change his gender. A train of thought that eventually led to the famous Croco-Mum theory which states that Crocodile is actually Luffy's mother and I mean that's just the kind of fun that Evenkov simply by existing brought to the series. However I should point out that in the Vismanga translation Evenkov's exact line is mm-hmm I know his weakness which is much less juicy than what we were led to believe at the time. As with this translation it could simply refer to the fact that his low gear powers are hard counted by liquid which would be a reasonable assumption but once again not nearly as fun to talk about. However with no confirmation to this day of exactly what Evenkov was referring to this will remain as an ever intriguing unsolved mystery. Number three, the egg on the Oro Jackson. All right he is a quirky mystery one that casual viewers or readers may not necessarily even know about. And first off that's because this entity was initially made known to us during chapter zero and episode zero which was the canon time material for one piece strong world. But whilst canon that means that not every fan would have clocked it at the time because it does exist outside of the Manga volumes. But this giant egg has gone on to appear on merchandise and become a huge topic of inquiry within the speculation of what could be inside. Suggestions have been made about it being a dragon egg or a griffin egg or any number of mythological creatures but we do actually have a tiny bit of information on it courtesy of the one piece blue deep data book which states that Roger had raised a mysterious creature the size of a sea king. So of course it must also be a possibility that the egg did house a sea king itself and perhaps to this day there is a gigantic creature out there in the world with a connection to the Roger pirates that one day may be encountered by the straw hats. Number two, where do devil fruits come from? Next up we have one of the most enduring questions of the entire series and whilst in the new old era we have come to know quite a bit about how devil fruits operate including their scientific effects on the beings that consume them via the manipulation of their lineage factor. However with all of this knowledge we are still actually no closer to discovering where devil fruits came from to begin with. Could there be some magical tree out there that grows them or were they artificially developed by the vague power of science some time in the past and possibly still currently? And this isn't just a mystery to us as the audience either because seemingly the entire one piece world is in the dark about devil fruits to the point where it is widely believed that their powers are a curse from the sea devil and in fact there are residents in areas of the world such as East Blue that don't even believe they exist at all. However we know better and to compound the mystery not all devil fruit powers provide a how shall we put this natural effect such as the Bukibukinomi consumed by baby five which allows her to transform into a wide array of entirely man-made weapons which leaves us with the thought that either the sea devil is on the ball enough to keep up with modern developments in human warfare or there is something more to this than meets the eye. However until this meeting of eyes occurs it will continue to be one of the greatest unsolved mysteries in the series but probably not greater than number one. What is the one piece? Now this seems like a bit of an obvious one so obvious in fact that it begs the question why it wasn't on the original top five unsolved mysteries list and my reasoning for that is fairly simple as despite it being the mystery that the entire premise of the series is based on in truth whatever the one piece itself just so happens to be doesn't really matter in the end. The point of setting out to find it according to our protagonist Sufi is to become the pirate king and more importantly have a great adventure of freedom and that mindset really has imprinted on me during my time with the series. As it stands I really don't care what the one piece ends up being nor does the main character and as such I deemed it to be a less important mystery than the ones I initially featured and quite possibly even the ones I featured on this list here today because the main difference between this and them is I want to know the answer to each and every one of those mysteries and I guess a lot of that may also be active denial in wanting to know the answer as to what the one piece is because the day that we discover the answer to that particular mystery is the day that we'll know for sure that the series is within its final chapters which after following it for so long oddly enough isn't a reality that I'm looking forward to. However, this time around I simply cannot deny the presence of the one piece on this list because this one question is why we began this journey over two decades ago. It is the original mystery from which all of these other tantalizing enigmas spawned and thus it reigns supreme here today. But that pretty much does it for another round of the top five greatest unsolved mysteries in one piece.

But with one important exception being his left eye which was now scarred and has not been seen in a state of open edge in the New World era. Yes, I'm aware that open edge isn't a word but deal with it.
