Originally a man of low birth but peerless ambition, Dio is a cunning villain of little conscience and has an insatiable hunger for power. After becoming a vampire and later a Stand user, wielding the all-powerful The World, Dio has gathered many minions around him and is responsible for many major events of the series. His legacy and influence persists throughout the first six parts of JoJo, with characters either being related to him or heavily inspired by him.
