Mochi Mochi no Mi

The Mochi Mochi no Mi is a Logia-type Devil Fruit that allows the user to create, control, and transform into a sticky substance. It was eaten by Charlotte Katakuri.

Etymology

 * "Mochi" is the name of a rice cake sweet, and can also be a descriptor for sticky things in general.

Strengths and Weaknesses
As a Logia, this fruit allows the user to turn their body into a sticky substance, making them nigh-invulnerable unless Haki or Seastone is used. The substance is thick enough to be used as a large blunt weapon, and is capable of trapping people due to its stickiness.

However, one can escape from the substance should a sufficient amount of water be applied to it. Fishman Karate is especially effective. Otherwise, the user is affected by the standard Devil Fruit weaknesses.

Usage
Katakuri uses his fruit in combat, and is capable of controlling large amounts of the substance with high precision. So far he has been shown turning his leg into the substance, and extending it to form a large, tentacle-like blunt weapon.
