I think Pluton is some sort of an armor for Zunisha that turns zunisha into the ultimate battleship.
Historically, elephants were used in war. This is why Momo is so important. If Zunisha becomes the ultimate battleship when exposed to the pluton armor, Momo is the captain of this battleship.
However, I think Teach will invade Wano and steal the pluton armor for himself. Sanjuan Wolf will obtain the armor and become the ultimate battleship.
I think this armor could work like the germa suit where it molds to the user.
In order to defeat Wolf, Franky will make his own pluton armor that he will give to The Sunny, turning The Sunny into Pluton.
So yeah I think pluton is both an armor for a battleship and the name of any battleship that wears the armor. Zunisha is supposed to become pluton, Wolf will steal the armor and become pluton instead, however Franky will make Sunny into the strongest Pluton.
