The shocking revelations about the true nature of the gom-gom fruit in the final chapters of ONE PIECE have shocked the entire community of enthusiasts, leading many of them to believe the existence of other fruits whose true potential has been hidden by the world government, even changing their name over the years.
Based on this idea, we come to the consideration The existence of other devil fruits associated with deities is plausible, just like the sun god Nika, whose powers Luffy seems to have inherited. In particular, I think back to the Shandia tribe and their strong belief in four gods God of the sun, rain, earth and forestit is interesting to think of the existence of fruits capable of transmitting powers belonging to such gods.
Although it is never stated that the sun god praised by the Shandia is Nika, for such a tribe so attached to the past and traditions, it also makes sense to pray for a legendary warrior like him.
Given the choice of the world government to cover up the true potential and name of the gom gom fruit, this is the case hard to speculate as to who might have inherited the deities' abilities mentioned above. However, apart from references to the ability to create forests, trees or plants associated with a fruit, there are two hypotheses relating to the powers of a rain god and an earth god.
The most linear concerns the stronger fruit of the Paramishia type: the Gura Gura associated with the god of the earth. First owned by Whitebeard and now in the hands of Blackbeard, allowing the possessor to create shock waves capable of penetrating any material and therefore also causing real earthquakes. That Awakening the potential of such a fruit could lead to manipulation of the earthmoving continents, shifting terrestrial conformity, awesome powers for a human.
On the other hand, the theory that would link them appears more forced ability of the rain god to the curious coincidences that occurred during Monkey D. Dragon's first appearance. In Chapter 100, Buggy is struck by a sudden and mysterious lightning just before he chops off Luffy's head in Rogue Town. Shortly after, Straw Hat is rescued again, thanks to a gust of wind that blows both Smoker and other Marine men away from him.
Although it has never been confirmed It might have been dragon that created the flash and commotion, a power that in the universe of ONE PIECE would easily fall into a hypothetical description of the fruit of the rain god. Let us know what you think of these theories by leaving a comment below.
