The world of ONE PIECE holds many secrets. One of them is undoubtedly the three ancestral weapons, three ancient forces that can shape the entire world depending on whose hands they fall. Poseidon, Uranus and Pluton, these are the names of such weapons that have not yet been sufficiently discovered by readers.
Surely ONE PIECE will explore the topic in the future and one of those could be the subject of the next phase. If we already know some things about Poseidon, including who he is, however, we know relatively little about Pluton. This Ancestral Weapon is a battleship that was used in ancient times and seems huge given how Franky and Iceburg reacted to the designs.
After all, very little is known except that it was built at Water Seven during the Void Century and kept in a secret location for the centuries that followed. As the poneglyph of Alabasta explains, this place is Wano, this is the island where the protagonists are now. It is therefore possible that within a few chapters, the Mugiwara will come into contact with their second ancestral weapon, which they can control for war against the Navy and World Government.
What capabilities will this weapon of mass destruction have? Meanwhile, Poseidon could also bring destruction in ONE PIECE.
