Jonathan Joestar

Jonathan Joestar (ジョナサン・ジョースター, Jonasan Jōsutā) is the protagonist of the first part of JoJo's Bizarre Adventure, Phantom Blood, and the first JoJo in the series. His legacy extends across almost all of the first six parts of the series, with Joseph Joestar and Jotaro Kujo being his descendants. Jonathan is the son of millionaires George Joestar I and Mary Joestar. He is an honest, lovable, and positive man whose life is turned upside down after meeting his adopted brother—and the series' antagonist—Dio Brando. In his duel against Dio, Jonathan becomes a Hamon user under the tutelage of his master, Will Anthonio Zeppeli. Jonathan is the biological father of Giorno Giovanna, the protagonist of Vento Aureo, and also of a handful of other illegitimate children.
