Dio Brando (JoJo's)

Dio Brando, known as DIO from Part 3 onwards, is the main antagonist in both Part 1 and Part 3. After becoming a vampire and later a Stand user, Dio has gathered around him many minions and is responsible for many major events of the series, from the death of Jonathan Joestar to the Joestar Family's sudden acquisition of Stand power, and his legacy persists throughout the series, effectively making him the main antagonist of the JoJo's Bizarre Adventure series as a whole. Dio is the father of Giorno Giovanna, the main protagonist of Part 5, as well as a handful of other illegitimate offspring.‎
