Yomu Yomu no Mi

The Wado Wado no Mi is a Paramecia-type Devil Fruit that allows the user to draw a variety of powers from the words written in a book held in their left hand by saying them aloud, making the user a Word Human. Wado is the Japanese word for "word". In an English dub this fruit would be called the Word-Word Fruit. It was eaten by Gregory Spafford.

Strengths and Weaknesses
The fruit allows the user to manipulate the diverse library of effects from the words of a book that the user is holding in their left hand at the time. These effects include, but are not limited to, enhancing one's physical strength, hindering the strength of others, regenerating health, quelling negative emotions, and unleashing powerful strikes.

One of the major drawbacks of the fruit is that a book must be held in the user's left hand for the ability to work, except in extraordinary circumstances. For some of the fruit's powers to remain in effect, such as making one's attacks stronger, the book must continue to be held by the user. If it is dropped or knocked out of the user's hand then the enhancement is cancelled.

Additionally, abilities applied to anything other than the user must be administered with the right hand. Because the user must touch the opponent the Wado-Wado no Mi is typically limited to close-combat.

As there are numerous books in existence, the differences between one over another are evident in the potency of abilities. Two books may both contain the word 'heal' but depending upon the book one will be more effective than the other. For example, a dictionary will not yield the same result as a medical encyclodpedia. The essence of strength drawn from any given book is tied to the author's heart in writing it. Regardless of the book, however, if the user deeply understands the heart of the author's words then the user's abilities will be more powerful. Spafford's strongest 'weapon', then, is his Bible. It's words are believed to be authored by God and are something he's studied since he was a child.
