Joestar George

Japanese name:

ジョージ·ジョースターI世

George Joestar I is Jonathan's father. He lost his wife in a carriage accident where he met Dario Brando. After Dario's death, Dio went to live with George and Jonathan at the Joestar Estate (because George thinks Dario saved his life so he takes in Dio as thanks, when in actuality George knew this was not true but still took Dio in).

SpoilersEight years later George falls ill from unknown causes. After Jonathan returned from Ogre Street, Dio attacked Jonathan with a knife, which George blocked and got stabbed in the back. George's blood lands on Dio, who is wearing the Stone Mask, turning Dio into a vampire as he dies.
