Bosu Bosu no Mi

The Bosu Bosu no Mi ( 声声の実 ) is a Paramecia-type Devil Fruit in which the user gets a voice-box thus giving them ability to talk. Bosu ( 声) meaning “Voice Box” in both Viz Manga, and the FUNimation dub, it is called the Chatty-Chatty Fruit. This fruit was “eaten” by Big Boss Teno Iza’s sword the Chizama and since then has become one of the most famous blades ever.

Strength
The main strength of this fruit as shown by Chizama is the ability gained by the blade is basically allowing it to talk; the blade had gotten a voice box. This fruit is one of the few that doesn’t seem to have a combat purpose; however this fruit has shown to have an odd affect. It was commented by Vegapunk, that this fruit wouldn’t be any good to humans. But to an object or such, it would allow that object to “speak” its mind.

Weakness
The user suffers the standard weakness of the devil fruit.
