According to spoilers for One Piece Chapter 1116, Uranus might have been disclosed much earlier in the narrative, but when exactly did it happen?
Poseidon, Pluton, and Uranus are the three ancient weapons that One Piece has long revealed exist. Each of them has a unique form, and they are all capable of sinking the earth. Poseidon, for instance, is a unique mermaid who can communicate with and rule over sea monarchs.
There have only ever been two mermaid princesses who could do that. There were two of them: Shirahoshi and the one who lived in the Void Century. In the meantime, Pluton, a massive warship, is presently submerged behind Mount Fuji in Wano Country.
Regarding the third ancient weapon, Uranus, One Piece has not yet formally revealed its identity. One Piece Chapter 1116, however, might imply that it was displayed from the beginning. There are spoilers for the upcoming Chapter 1116 in this article.
Uranus might have been revealed in One Piece in Chapter 1060.
Though this is just conjecture, Uranus might have been the weapon utilized in One Piece to destroy the Lulusia Kingdom.
There were theories before the Lulusia Kingdom was destroyed that suggested Uranus or Imu would use their own might as a weapon to destroy the kingdom. But when Mother Flame was brought up, all theories were shot down because it was thought to be a weapon. It was made some time ago by Vegapunk, but the World Government abused it to destroy a nation that was in rebellion.
A part of Mother Flame was purloined by someone to power an antiquated weapon, according to One Piece Chapter 1116. It just has a small flame left because of this. Gorosei and Imu both realized that they would require Mother Flame in the future.
The world can be sunk by ancient weaponry. It was only employed once by the World Government, but it resulted in a one-meter rise in sea level. Lulusia vanished completely from the map. Before the attack, Sabo explained, something very black had been soaring above the clouds and a huge shadow had blanketed the sky.
It’s still unclear how serious that shadow is. But Mother Flame isn’t really a weapon; it’s just a flame. All indications suggest that Uranus was already disclosed in One Piece Chapter 1060. But until the manga explicitly states otherwise, we are unable to guarantee.
