I was pretty confused by the resurgence of Rain God theories out there - I had assumed Oda had retconned/renamed the Rain God from Skypeia with the Sea God now based on the Harley texts. They're both water based, so I didn't really think much of it - whether its Rain or Sea.
But... what if both exist? (*Note - ignoring the Elbaph/War God for now).
In the Harley text, we see the Sun, Earth, Forest, and Sea Gods get called out.
In Skypeia, we see the Sun, Earth, Forest, and Rain Gods get called out.
In Fishman Island, we see the panel below:
What if the Yonka + Yonka 2 parallels are the Sea and Rain? Rest are Earth, Forest, Sun.
I could be digging for something that isn't there - but the combination of (1) Yonka 2 existing at all and (2) no acknowledgement by Oda (as far as I know) on why there is Sea God in Harley but Rain God in Skypeia - that makes this seem like I could be onto something.
But what that means in terms of the story? Not sure really. Honestly - the Sea God part is confusing and can really only point to Davy Jones or Imu or something. Poseidon (Shirahoshi) is an ancient weapon; not a god.
Would love to hear thoughts, thanks for reading!
