Nika is a godly being because not only he is the user of most powerfull Mythical zoan, he also the onepiece, which was the combination of 3 ancient weapons . According to oda One Piece is not something like "the journey it is, in fact, a physical reward with unimaginable value.
that only makes me think onepiece is the totality of 3 major powers, this might sound dumb. but onepiece is a Being, it was already hinted in the logo of Onepiece,
hmmm. How's that Happened?
in my theory Onepiece is just a person who possess all ancient weapons. Joyboy is a onepiece and before he dies, he divided this abilities distributed anywhere animate and in animate object. that's the reason why shirahoshi wields poseidon.
and the the 3 ancient weapons are
Poseidon: masquerading into a Host User
Uranus: Nika Masquerading into a Paramecia.
Pluton: Yami Yami no mi Masquerading into Logia.
feel bad for Luffy haters, they are already in Riot and luffy was just acquired fraction of Joyboys power what else if he acquire more
