The legendary figure of Batman existed in ancient Japan as Samurai Batman, a brave and strong warrior who pitted his skills against the evil warlords, or daimyo. Armed with his powerful, slashing no-dachi sword and protected by a customized samurai armor costume, Samurai Batman swept across the countryside, cutting down villainy and protecting villagers at every turn. On the battlefield, Samurai Batman could always be identified by his hata-jirushi banner, which streamed behind him in every conflict, striking fear into the hearts of his opponents.
