#10-Florian Triangle
The Florian Triangle, (literally translated as Zone of Demonic Triangle) is a stretch of sea that one has to cross over when heading from Water 7 to Fishman Island. It is covered in a fog so thick that it blocks out all sunlight. According to Kokoro, many pirate and commercial ships mysteriously go missing every year and, sometimes, a ship will be found sailing without any people aboard. It has also been said that there are many haunted ships with dead bodies sailing across the sea.
#9-All Blue
The All Blue is a mystical sea of legend, rumored to be the only place in the world where the North, South, East, and West seas meet. In this legendary ocean, it is said that there are fish from each of the four seas, and to have such a resource at one’s disposal is the ultimate dream of every chef. Sanji strives to find this ocean of dreams. It is said that All Blue is found in the Grand Line.
#8-Who’s Luffy’s mom and is she alive?
Luffy’s mom is never introduced in One Piece at all and there’s really no info out there about who she really is.
Recently, the voice actress behind Luffy told fans something creator Eiichiro Oda told here awhile back. Mayumi Tanaka has voiced Luffy since day one, and the actress was curious about the boy’s birth mother. When she asked Oda about the topic one day, Tanaka said Oda wasn’t interested in exploring that side of Luffy’s heritage.
#7-Where and what is Uranus?What is the connection between the Ancient Weapons and the Void Century?
The Ancient Weapons are three weapons capable of mass destruction, each taking a different form. They are known as Pluton, Poseidon, and Uranus, each named after a deity for their godly powers.
While Pluton has yet to appear in the story, it has been referred to as an ancient battleship capable of massive damage and destruction. It is currently located in a secret cavern at the foot of the submerged Mt. Fuji in old Wano Country, below the cavern where Wano’s Road Poneglyph is currently hidden. In order for Pluton to be released, the walls surrounding Wano would have to be brought down. This is the true meaning of “opening Wano’s borders”.
Poseidon is Shiraoshi, a giant mermaid that has the power to talk to Sea Kings, enormous sea creatures capable of mass destruction.
Nothing is currently known about Uranus, except its name. Given the nature of Pluton and Poseidon, Uranus could easily be an animate lifeform or an inanimate object.
#6-What happened during the Void Century?
The Void Century is a century-long gap in recorded and archaeological history, the study of which is forbidden by the World Government. These events occurred 800 to 900 years before the current storyline. It was hinted at during the Skypiea arc; the dates were seen in Robin’s flashback.
