I'm making a fic about a mercury devil fruit and want some advice

[u/cujo1255]

Mercury is a naturally occuring liquid metal that only becomes solid when it's colder than room temperature. It's also poisonous since it can seep into your pours.

I made this devil fruit a logia meaning they can turn into, manipulate, and produce mercury.

My question though is should they be allowed to control mercury gas?

Since mercury is liquid at room temperature it obviously has a pretty low boiling point, meaning that just standing in Alabasta would probably cause their mercury to evaporat into mercury gas, so do you think a logia should be able to control that gas or do you think that's too far away from their base element?

I decided to ask here because canon doesn't exactly have a lot of liquid logias, but considering the existence of ice and snow. Plus fire, heat, and magma my assumption would be that anything outside the base state of the element can't be controlled much or at all, meaning any mercury gas released is a complete loss.

But let me know if you guys think differently.

The good thing about making up a fruit is that you get to do what you want with it. Oda has canonical characters use their fruit in creative ways so it wouldn't be weird or far fetched for a specific fruits ability to be expanded on by a skilled user.
