When Nukid was young he grew up on the same island as pirate Monkey D. Luffy. They became like brothers but they both went their seperate ways after Luffy became a pirate and Nukid joined the navy. I was given a chance to train for the CP9, a group of elite assassins who were trained in the Rokushiki, the ultimate martial arts. After years of training Nukid eventually joined along with fellow trainees Maria Scotts, whom he considered a pain. They both immediatly proved their worth to the CP9 and Nukid hoped he could one day defeat Rob Lucci
