Episode 1

Dio the Invader is the first episode of the JoJo's Bizarre Adventure anime.

Summary
In the year 1868, a carriage accident had occurred which had been carrying a couple and their baby son. A theif named Dario Brando and his wife saw the crash and decided to steal whatever valuables there were from the corpses. The nobleman George Joestar had survived the crash, as did his son, but his wife had died. Thinking Dario had come to save him, George offered Dario a reward for his "help". Years later, Dario, on his death bed, tells his son Dio of a debt that a man owed him. He tells Dio to go to the Joestar mansion to pay the debt. Not long afterwords, Dario dies and is buried. As a "goodbye", Dio spits on his father's grave.

In another area, two kids are bullying a small girl named Erina Pendleton by taking her doll. However, a young boy named Jonathan Joestar intervenes and helps the girl. While he gets beaten up by the bullies, he's able to get the doll back.

Soon after, Dio arrives at the Joestar mansion and meets Jonathan. Jonathan's dog, Danny, comes running towards them but, without a thought, Dio knees Danny in the jaw. Jonathan becomes enraged by this. Dio then thinks to himself that he now must destroy Jonathan mentally in order to gain the Joestar's wealth.

Since then, Dio has defeated Jonathan in a boxing match, isolated him from all his friends, kissed Erina, Jonathan's love affair, and burned Jonathan's  dog in an incinerator. Towards the end a duel breaks out between Dio and Jonathan, but is eventually stopped by George.
