Roronoa Zoro Timeskip

Roronoa Zoro, also known as "Pirate Hunter Zoro", is a pirate, former bounty hunter and the secondary protagonist 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 Luffy. His fame as a master swordsman and his great strength, along with the actions of his captain, sometimes lead others to believe he was the true captain of the crew earlier on. He is one of the top three fighters in the crew alongside Luffy and Sanji, and his dream is to become the greatest swordsman in the world. Zoro was regarded as one of "The Eleven Supernovas", the eleven rookie pirates with bounties over Beli100,000,000 to have reached the Red Line before the two year time skip, with a current bounty of Beli120,000,000.

After the Timeskip
After the two-year timeskip, Zoro gains a new scar running down his left eye, which is now implied to be blind as it is always closed. His neck appears much thicker and more muscular and his hair became a little longer, now slightly slicked back. Zoro now wears a long, open dark-green coat, closed on his waist by a red sash, in which his swords are now tucked, and his black bandanna tied around the left sleeve. He has no shirt underneath, and his green haramaki is visible under the coat. He also appears to have gotten taller, as he seems to be as tall as Robin now when standing next to her.
During the Punk Hazard Arc, he wore a white furry coat for protection against the cold weather on the frozen side of Punk Hazard, which he took from Brownbeard's Centaur Patrol Unit.
