Zumu Zumu no Mi

The Zumu Zumu no Mi is a Logia-type Devil Fruit that allows the user to create, control and transform into ectoplasm at will, turning the user into an Ectoplasm Human (外物質人間 Gaibusshitsu Ningen). "Zumu" is derived from the Japanese pronunciation of the word ectoplasm, "ekutopurazumu" (エクトプラズム). It was eaten by Valentine.

Trivia

 * The term Gaibusshitsu is translated as "outside material" instead of "ectoplasm", which is the literal definition of the word (from the Greek ektos, meaning "outside", and plasma, meaning "something formed or molded").
