Beta Beta no Mi

The Beta Beta no Mi is a Devil Fruit that allows the user to create and become a sticky substance. It was eaten by Trébol.

Strengths and Weaknesses
The fruit's major strength is the invulnerability the user gets, as he can transform in a sticky substance, protecting him from harm.

Also, Trebol uses it for sticking to various surfaces, such as roofs or walls. By producing this substance, he is also able to keep his target in place (or making moving more difficult for them).

Aside from the standard Devil Fruit weaknesses, this ability has no other known vulnerable point.
