Riri

Is it possible that is she were to stay hidden under the sea that her powers won't be in the database? Or at least not well known since she's been hiding for at least 100 years under the sea?

Also would someone with ice powers be unaffected from the sea since they can freeze water molecules? Still affected by sea stone though and on that topic would the seastone affect the diamond girl when in diamond form since she's a literal rock so would a rock affect a rock? Or like just turn her back to human form? Kinda like mystique? So also long as seastone is touching her she is unable to turn diamond or manipulate them but she would still be incredibly strong and dare I say it as strong as a diamond so she'd still be bulletproof and cut/stab resistant so seastone Would only affect half of her and she's smart en5to know that as long as shes in diamond she can live in the sea floor of need be

Follow up question, if your devil fruit gives you the ability of turning into a diamond form and manipulation, does that mean in diamond form which she doesn't need to eat nor breathe because she is a pure diamond in this form she would be stuck forever in the sea floor forever or until found? Like a diamond statue calling out like a siren?

Ok so I'm theory if there is a body of fresh water or running rivers off of mountains that even with a devil fruit would you be able to swim? For instance what if your devil fruit turned you into a crocodile or turtle would you still be able to swim and have all your strengths in fresh water? In terms of turtle even under seawater you could chill in your shell cause then all you have to focus on is holding your breath and seeing how turtles in general can hold there breath for a long time a turtle that is human size could hold there breathe longer due to having larger lungs? I'm writing a fan manga and this info would be very useful cause even with electric powers in fresh water you'd be unstoppable in the water since you can use it as a conductor
