Here are 10 things we know about Gorosei in One Piece:
1. There is 1 Gorosei whose name is known
The first Gorosei whose name is revealed is Saint Jaygarcia Saturn.
2. They are high-level Dragon Stars
But as high-ranking Dragon Stars, the Gorosei also have the right to summon naval admirals if they are attacked.
The Gorosei members like Jaygarcia Saturn also have the title `Saint` in their names, like the Dragon Star Charlos or Rosward.
3. The ruling class of the World Government under Im
Even when Jaygarcia Saturn was introduced in chapter 1073, his title was `The World’s Highest Authority, the Five Elders`.
Gorosei also has control over Cipher Pol, an intelligence organization within the World Government.
4. Appearance has not changed after 20 years
This raises various questions for fans, what exactly happened to their bodies?
5. Consider the Nefertari family as traitors
In One Piece, Nefertari is one of the 20 noble families that founded the World Government.
On this basis, the Gorosei considered the Nefertari family traitors.
6. Learn the secrets of the Void Century
A Gorosei even ordered Spandine to shoot one of the archaeologists in Ohara, because he was about to tell the true name of the Ancient Kingdom.
7. Have the right to activate Buster Call
Not only that, the Gorosei also have the right to transfer the rights to use Buster Call to others as they deem appropriate.
8. Have combat experience
For example, Gorosei looks youngest on the left of the photo, he has a long scar on his chest, Jaygarcia Saturn has a scar on his face.
Even the Ngu Elder Star’s muscles look very solid, showing that they seem to still exercise regularly until now.
9. Understand the meaning of `D’s will.`
10. Be willing to spend time talking to Shanks – a pirate
As a criminal as well as a pirate, Shanks’ arrival at Mary Geoise when the Levely conference was held was indeed strange.
In One Piece Film: Red, the Gorosei seem to suspect that Uta is part of the Figarland family.
