Just a fun idea that came into my mind

The idea is that Imu has a Sun god fruit as well.

From the new spoilers we know there are different interpretation of Sun gods in elbaph and that from people's desires and wishes arrive the devil fruits.

There are three Sun gods ( I know it's a stretch to call it a third one)

1st Luffy one ie a liberator and the one who laughs

2nd Loki one ie the one who destroys the world

3rd The Sun god whom giants want to become and rule the world

What if the third one is actually Imu. Since the bearer of the fruits have the characteristics of thier respective Sun gods. Like Luffy frees people and Loki has the desire to destroy the world, the bearer of a ruling Sun god fruit would want to be a ruler if not be one already.

I think Imu can be this Sun god and this version is the same one that the Shandians prayed to. This Sun god being a serpent ( Imus form looks like one) is what lead the shandians to view Kashigami as a god of theirs.
