Dio Brando (ディオ・ブランドー Dio Burandō), known as DIO from Part 3 onwards, is the main antagonist of 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.

Dio is the father of Giorno Giovanna, the main protagonist of Part 5, as well as a handful of other illegitimate offspring.‎

DIO dons a jacket with a tight tank-top underneath, as well as chaps with an exposed crotch. His face is now in full-view, and on his head is a heart-shaped circlet to match his knee guards. This is his form during the beginning of the DIO’s World story arc. In most depictions of him, DIO’s outfit is tinted orange or yellow.

He also wears a necklace covering his neck scar and heart motifs above his feet and on his pant legs, but he quickly stopped sporting them after his first stairway confrontation with Polnareff.
