The Bari Bari no Mi is a Paramecia-type Devil Fruit that allows the user to generate barriers for defending with or striking with at will, turning the user into a Barrier Human. In an SBS Eiichiro Oda revealed its Barrier Capacity.
Question: “Oda-san, hello~. About Bartolomeo, he said something about how his barriers have a limit or whatever, so how many Bari-Bari’s worth is its maximum capacity?” P.N. Hoichael Jackson
Oda: “Great question. There is in fact a limit to the space his barriers can cover, as well as how many barriers he can put up at a time. He can only hold up one barrier at a time, and they say that this one barrier can cover up to 50 thousand Bari-Bari’s!! Amazing!
1 Bari-Bari equates to roughly 100x that of 1 Bori-Bari-Bari, so in other words, his barrier capacity is just about 500 Pickle-Pori-Pori-Bari-Bari’s.”
(Translator’s Note: Bari, Bori, and Pori are all Japanese sound effects that roughly translate to ‘crunching’.)
