Zoro
The Straw Hat Pirates' primary combatant, one of their two swordsmen, one of the Senior Officers of the Straw Hat Grand Fleet, and the acknowledged right-hand man of their captain, Monkey D. Luffy, is Roronoa Zoro, popularly known as "Pirate Hunter" Zoro. He was the first person to join Luffy's crew in the Romance Dawn Arc, and he was previously a bounty hunter.
Zoro was a bounty hunter before he met Luffy in One Piece, which led to a life transformation and the creation of one of Luffy's first crew members. Zoro is interesting because, although at first, he detested pirates and even tried to put an end to them, in the end, he turned into the one thing he detested the most.
Zoro is consistently ranked in the top three most popular characters, typically trailing only Luffy in terms of popularity. Except for the fifth one, where he came in third place behind Trafalgar Law, he placed second in every Shōnen Jump character popularity poll. Although Zoro's past was addressed in "Episode 19," ardent Zoro fans wouldn't object to an appearance by the adored character in a television program. Supporters would swarm to see a fresh perspective on their beloved pirate, regardless of whether the spinoff would concentrate on Zoro's earlier exploits or take a different approach and have Zoro become command of his own crew.
