Ryuma Shimotsuki
Shimotsuki Ryuma, a legendary and world-renowned samurai from the Shimotsuki Family of Wano Country, lived during the “Country of Gold” era centuries ago. Celebrated for his unparalleled swordsmanship, he earned the title of Sword God and was famous for slaying a dragon. Ryuma is also a direct ancestor of Shimotsuki Ushimaru and Roronoa Zoro.
Twenty-three years before the current storyline, Ryuma’s consecrated grave in Ringo was desecrated, and his corpse, along with his sword, was stolen by Gecko Moria. Eventually, Ryuma’s body was reanimated using Brook’s shadow and turned into a General Zombie to serve Moria on Thriller Bark. This led to the possessed Ryuma becoming an antagonist in the Thriller Bark Arc until he was defeated by Zoro.
