The Meta Meta no Mi is a non-canon unknown-type Devil Fruit that allows the user to control liquid metal, making them a Liquid Metal Human (液体金属人間,Ekitai Kinzoku Ningen?). It was eaten by Graydle.
The main strength of this Devil Fruit is that it allows the user to generate and manipulate liquid metal.
Graydle is able to split himself and function in many communicating parts, creating clones of Zoro, Sanji, and himself out of metal to fight for him, which he did in their final confrontation. As such, he is able to impersonate groups of humans, such as Marine soldiers and dogs. To search large areas in urban environments, Graydle also uses the fruit the make a prosthetic arm for himself, which he can make bigger or turn into a blade.
Aside from the standard Devil Fruit weaknesses, there seems to be no known weaknesses to this power.
