Background of Jonathan Joestar in JoJo's Bizarre Adventure
Jonathan Joestar was born on April 4, 1868, in the United Kingdom of Great Britain and Ireland. His parents, George Joestar I and Mary Joestar were very wealthy because his father used to be a businessman. They later adopted Dio Brando, the son of a criminal, Dario Brando, but after he passed, George decided to adopt him as Jonathan’s brother.
Jonathan was kind to Dio from the very start, even though Dio killed his beloved dog and kissed Erina Pendleton, who used to be Jonathan's love. Dio used to torture Jonathan even when he gave him so many chances to change, but he did not, and later, he got influenced by the Stone Mask.
