Wano in itself is a force of nature. It is a natural fortress that overshadows the seas. Zou is similair, it is colossal and overshadows the seas. The perfect pieces for an ultimate weapon that watches over islands and is capable of destroying them.
I think that Pluton is not only a "ship" it is a "ship canon".
Wano is so spectacular we almost uncovered evrything, but one thing is particulary standing out, something we saw over and over in the Wano arc:
Mt Fuji! Or atleast the Wano equivalent to it: the big, suspicious looking volcano rising above Wano!
This volcano seems still to be fueled with magma, something where we saw Kaido and Big Mom ironically been stomped into. Their fate to fall down and witness Pluton...they finally could lay their hands on it lol.

I think that Zunesha is they key to open Wano and set up the canon that maybe has the capability of destroying the Red Line.
One Piece from here on has to scale upwards and we need pay-off especially in the worldbuilding aspect. Zunesha will level down Wano and with that Mt Fuji will be fully loaded. Pluton will be able to be utilized by Momonosuke once Wano is opened.
Thoughts?
