zatoichi vs. leonidas
well if you base it on the 2003 movie you wouldn't have seen what zatoichi is capable of. You are putting a real guy against a fictional character with supernatural powers (like daredevil).Let me begin by mentioning bronze is way softer than steel. I wouldn't be surprised if Zatoichi could cut his spear as it is coming at him. Also Zatoichi just doesn't "see" by hearing he also feels the air moving around him so the second that Leonidas goes to throw the spear he is already anticipating and would more than likely block or dodge or even counter attack. Although he has never blocked a heavy spear there has been an instance where 7 or 8 spears have come at him at one time and he managed to dodge them all because Zatoichi is practically a super hero. He would win in any scenario because he was created that way. If it was real life the blind guy would get pwned.
