Only hardcore one piece fans have at least a concept of their own one piece character. Come on!! Tell us about it!
My Pirate is a first mate/swordsman on a crew with the power of a devil fruit called Sho-Sho no Mi, which grants the user to create clones of himself. (like Naruto's Kage Bunshin no Jutsu) The only way to defeat the clones is to throw them in seawater or hit/stab em hard enough. If he is holding something, that is cloned also, for example a sword, which means he has like 50 sword style.
What are your Pirates like? come oooooooon, dont be shy ^-^
