Roronoa Zoro is a pirate, former bounty hunter, and one of the main protagonists of One Piece. He was the first member to join the Straw Hat Pirates, and to date is considered the largest threat and most dangerous member in the crew after the captain Luffy. He is famed as a master swordsman, user of the Santoryu style
(3 Swords), and his great strength (and the actions of his captain) sometimes leads others to believe he must be the true captain. Being labeled as one of the "Monster Trio", he's one of the top three fighters in the crew. His dream is to become the greatest swordsman in the world. Zoro was labeled as one of "The Eleven Supernovas", the eleven rookie pirates with bounties over 100,000,000 beli to have reached the Red Line.

Revy does most of the fighting for the Lagoon Company. Very little is revealed about her past, although portions can be pieced together through the series. Revy is a Chinese-American born and raised in Chinatown, Manhattan, near Mott Street, spending most of her youth as a thief and murderer. Flashbacks throughout the series reveal that Revy may have honed her skills with firearms by shooting at cans, and that her first murder may have involved shooting an unknown man while using a pillow. It is unknown whether the pillow was used to suppress the noise or to help avoid looking at her first victim. Revy is very competitive, easily bored, and extremely ill-tempered. Unlike Rock, she is undiplomatic, believing in the use of brute force and coercion to get her way. In contrast to this, she's revealed to be highly ticklish.
