What if Zunesha is a devil fruit user?

Now, we dont know much about Zunesha, outside of them being a thousand years old, that they were a friend of Joy Boys, and that they committed a "crime" 800yrs ago.

But what if theyre just a person or giant or such with kind of mythical devil fruit? If true, the sea wouldnt be effecting them, cause theyre just walking in it. San Juan Wolf can use his DF power while walking in the ocean, because hes so tall.

What about their age? Well, the immortality surgery exists, and we havent seen anything be done with it yet. Zunesha was alive a full century before the void century, who knows what was happening then.

I recognize that this is pretty absurd, and that it only slightly has legs to stand on due to lack of evidence. But its a fun thought experiment anyway. And it would be really funny if true
