Theory Imu has a copy of Poseidon and Pluton

[Monkey D Theories]

It wouldn’t make sense if Joyboy was the only one who had ancient weapons.

If he was then how could he have ever been rivaled by the WG?

It doesn’t make sense. Imo Imu also has copies of these ancient weapons, and that this was how Imu sunk the world.

We already can assume, based off Vegapunk’s words, that the UFO of Imu’s was likely Uranus. It wouldn’t be a stretch to assume he has copies of the other weapons as well.

Pluton is just a ship. Given it existed during the void century I’m sure Imu could have gotten his hands on one. He probably keeps it locked up, just like with the UFO. The WG is essentially unrivaled. The marines alone are stronger than any individual yonko. The yonko and the Revos only exist because Imu either doesn’t care to stop them, or he is okay with them existing.

Regarding Poseidon. I think it’s very likely that Imu also has this weapon. This is why Roger couldn’t have rebelled against the WG, why he needed to wait for Shirahoshi to be born. Poseidon’s power wasn’t needed for the mere sake of it. Rather having a Poseidon of his own would have been the only way for Roger to counteract Imu’s Poseidon.

What is Imu’s Poseidon? I have several thoughts.

1. Imu literally made the original Poseidon immortal, has her chained up in mariejois, and can control her using some DF or technology
2. Imu stole Poseidon’s power before she died. Perhaps the power of Poseidon comes from the voice of the Mermaid princess. Perhaps Imu can mimic this using DFs or technology. Perhaps he stole the original Poseidon’s corpse and had a Kage Kage no mi user turn it into a Zombie. Perhaps the previous Ope Ope no mi user gave Imu her vocal chords. Perhaps he had Saturn clone the original Poseidon and he raised the clone as his daughter or something.
3. Imu himself can use Poseidon’s power using voice of all things and/or an advanced conqueror’s haki technique

In any case, Joyboy couldn’t have had all the weapons. For Imu to have won and sunk the world, imo he must have had most, if not all, of the weapons.

whole point of water 7 was that the WG doesn't have the pluton and wants the blueprints badly. unlikely they know about the existing, stashed pluton, as the nefertaris kept their poneglyph a secret from the WG.

they might have some poseidon equivalent since they either don't know about shirahoshi or don't care.
you're correct though that they badly want to acquire all three, but they don't have da pluton
