Diplo

Diplo
Diplo (ディプロー) is a stand that is a humanoid composed of clay. It turns the user into clay, and if the clay is somehow removed from them, they lose their abilities.

Abilities
It makes the user turn into a liquid inconstant clay-like texture that allows the player to morph into any person, animal or object. (Similarly like the Pokémon Ditto)

Appearance
Basically like a really messy gray dough in the form of a man, doesn't have any other remarkable characteristics besides that, only that it has an specific or random symbol that resembles the user.
