Tatsuya Sylvester (竜嫌シルベスター, Tatsuya Shirubesutā) is a notable Pirate of the New World who sets his sight towards the One Piece, like several others within the said region. Tatsuya is famed by the name of "The Roaring Dragon" (轟竜, Gōryū) due to his loud nature, and the manner in which he exerts his powerful Haoshoku Haki. Along with this title, Tatsuya is known by some as "The Father of Nature" (自然の御父さん, Shizen no Otō-san), primarily because he has entirely conquered whole environments on his own with his tremendous combat skills, as well as his ability to get along with almost any kind of fauna within these areas.
