A Jojo
What DIO screams like a madman every time he sees a Joestar, and it’s also what every Joestar’s name starts with.
DIO just screamed 'JOE!' like he was being tortured by a million cows.
When he saw Jonathan, he screamed 'JOE!' so loud the neighbors called the police.
DIO started yelling 'JOE!' in the middle of a pizza shop and got thrown out.
