Zoro is one of the most powerful One Piece characters and quite easily one of the most infamous ones as well in the Grand Line. Having started his journey as a Bounty Hunter who made a living by hunting pirates, Zoro's start to the story was rather interesting. However, his career as a bounty hunter came to an end rather abruptly when he was saved by Luffy and recruited by the Straw Hat Pirates. Ever since then, Zoro has loyally served Luffy, and he will continue to do just that right until the very end.
