Does the MC eat that Ancient Zoan fruit he got a few chapters ago? Because it seems like a good chance to gain strength. He doesn't really need to worry about the weaknesses either because of Geppo (isn't gonna fall in the Ocean/Sea if he's not an idiot) and if he's not an idiot, he shouldn't get hit by a Seastone weapon or whatever. The pros outweigh the cons, at the very least.
