The Ekuto Ekuto no Mi is a Logia-type devil fruit also known as the Ecto Ecto Fruit, ecto being short for ectoplasm. It is a supernatural element that can be found in haunted houses, shipwrecks, but most abundant in the afterlife. Many actually believe this devil fruit can only be found in the afterlife. The element itself appears as semi liquid and gas, and is luminescent in the dark.
Like all Logia-types it gives the user the ability to produce and control their element as well as regenerate. The user and their element are able to diffuse through solid objects which makes them difficult to escape or catch. The user can cause supernatural activity, by absorbing energy in their surroundings causing light sources to flicker and fail and making the atmosphere much colder. This fruit also gives the power to possess any number of nonliving objects such as household objects, weapons, and corpses. This fruit's power is most powerful in the dark.
While powerful in the dark, this fruit's power is weakest in the light and the user will often try to avoid the light. Ectoplasm will dissolve when exposed to electricity. Some believe the user is haunted by all those they kill after eating the Ekuto Ekuto no Mi. Standard devil fruit weaknesses apply.
