I have this obsession with the mysteries that Oda left in One Piece. I read weekly the manga since 2007 and really love the series and reread a lot (i even have a YouTube channel dedicated to it).
So, i did a list reuniting all the mysteries, loose ends and questions without answers that we have in the story up until now. I read through all the manga multiple times, read the SBS, read most of the wiki articles, read Library of Ohara posts (including the Vivre Card ones) and look of other people's lists to see if i missed anything.
If you see anything that you think is wrong or other mystery that i forgot to mention, comment right below. I want to constant update this list as the series goes on and see what questions will be answered in the manga or in another way (like Vivre Cards, etc).
I also separeted the list in 17 categories, so it is easier to read and find the topic.
So, here we go, 211 mysteries! I hope you guys like it 🙂

I also have scrapped questions that i don't think it was worth it to put in the main list. It has some theories that i read and is based in mixed things that are and aren't really in the manga. So check it out!
19 Theories and Scrapped Questions:
Kuro and Don Krieg have chances to return?
Will Ryogyoku and Fujitora oppose GM as mentioned in Momotaro's theory?
Will Carrot betray the Mugiwaras? Because her Vivre Card has a different color than the other Mink.
There is a fourth All-Star? Apparently a silhouette appeared in an illustration from an OP magazine.
Are there dragons or have there been?
Does Donquixote's constant smile come from SMILE?
By the end of the series, will we have any idea of the total islands in the world of One Piece?
Does the dragon tattoo seen on a member of the Shanks and an Okama have any meaning?
Will any Straw Hats die until the end of the series?
Makino is the daughter of Shanks. Yes there is this theory... I just put here because i though it's funny, honestly.
If Whole Cake was Sanji's arc, Wano is supposed to be Zoro's, Elbaf would be Ussop's, will we have another arc before the end for Nami? Completing the top 5 (with Luffy having Laugh Tale to reveal his mysteries?)
Next island is Elbaf and could maybe the island is protected by Shanks.
Will we see the past of Borsalino and Sakazuki?
This me being stubborn: Will the similarity between Kuina and Tashigi ever be explained, or is it just a coincidence, as it has been put on several occasions?
Can Sarquiss, Pound, Monet, Vergo and Pedro be alive? Well, Vivre Card doesn't say much if they are. And we know how OP is about killing characters ...
For those who ask: The "them" that Luffy and Zoro say Blackbeard in Jaya may have been a problem of interpretation, since even Blackbeard having a double or triple personality, they could not recognize it at that time. But i put it here anyway...
Buggy. Will we see more of his past?
Zeff's reward. Does he have any mystery about his past?
Ussop's role in Elbaf. Will he became the greatest warrior of all???
That's pretty much it. Thank you for reading up until now!

And to finish, i already mention my YouTube channel. If anyone here knows portuguese and want to check it out, here you go: youtube.com/SamuraiMorcego
I also made a video about this list. It's a little dated because it didn't have some of the new mysteries. I made it two weeks ago. But check it out if you have interest to look some visual evidencies of most of the mysteries that i put on the list:
So that's it. Thanks for reading!
