Intro. roronoa Zoro was once a pirate hunter but he would be kidnapped by the navy and now he wants to become a pirate. He made his own group: (Monkey D. Ruffy, Vinsmoke Sanji, Usopp and Nami). He didn't say anyone that he is Roronoa Zoro. He looks around his head without his cloth, completely different. He only wears his cloth when he fights, otherwise not at all.
