Rubi Rubi no Mi

The Rubi Rubi no Mi is a Paramecia-type that allows the user to create, control, and transform into Ruby at will, making the user a Ruby Human (ルビー人間). It was eaten by Queenie.

Etymology

 * "Rubi" is the Japanese pronunciation of the word Ruby.

Strengths and Weaknesses
The fruit allows the user to turn into Ruby, giving them a very tough body, as well as the ability to produce and manipulate Rubies separately form their bodies.

Other than that, the user is affected by the standard Devil Fruit weaknesses.
