"Useless, useless!!! (無駄 無駄!!!)"

- Dio Brando's battle cry

Dio Brando (ディオ・ブランドー), known as DIO from Part 3 onwards, is the main antagonist of both Phantom Blood and Stardust Crusaders. He is also a posthumous character in Stone Ocean being the one responsible for Enrico Pucci's rise to villainy.

Originally a man of low birth but peerless ambition, Dio is a villain of little conscience, vast cunning, and an insatiable hunger for power. Becoming a Vampire and later a Stand user, Dio Brando has gathered around him many  minions and is responsible for many major events of the series such as the death of Jonathan Joestar and the Joestar Family's acquisition of Stand power. Thus he is a dominant character whose legacy persists throughout the series.

Dio is the father of Giorno Giovanna, the protagonist of Vento Aureo, as well as a handful of other illegitimate offspring.

Childhood
When he first arrives at the Joestar Estate, Dio is seen wearing typical formal boy's attire from that era; a blue coat, white dress shirt, a tie, suspenders, breeches, and a pair of striped socks. He has blond hair and a handsome face. He also has 3 moles on the lobule of his left ear.

Adulthood
Aside from replacing his coat with a vest, Dio's attire hasn't had much change. However, his overall physique and height have increased significantly. During the events where Jonathan sets out to find the antidote for his father's illness, Dio dons a top hat and a new flamboyant looking cloak that has feathers jutting out of the shoulders.

Vampire
Dio undergoes drastic physical change upon using the Stone Mask to transform into a vampire. His formerly clean hair becomes messy and unkempt, his eyes become sharper and adopt a darker outline, and he develops fangs. His clothing has changed quite a bit as well after his first battle with Jonathan; most noticeable is the scarf around his neck. He wears an ornate dual-colored shirt and matching breeches, a large pair of boots, vambraces, and two suspenders attached to a band around his waist.

Shadow
DIO does not have a visible face as an effect of the shadowy darkness of his mansion. He has shoulder-length blond hair. He is topless, exposing Jonathan's muscular body (on which his head is sewn in place) and wears green pants with suspenders, gray clogs, black shiny cuffs on both wrists, and, matching his stand, he wears heart-shaped knee guards. In the game JoJo's Bizarre Adventure: Heritage for the Future, his voice is also distorted (an effect created by the developers to add a sense of mystery). This form of DIO is also called "The Evil Incarnation DIO".

Revealed
Just like the Shadow form, only DIO's entire suit is now colored yellow, with green straps. DIO's face is seen, his hair has remained blond, and he is wearing a jacket with a tight tank-top underneath, as well as chaps with an exposed crotch. He now also wears a heart-shaped circlet, and glossy rings for his cuffs. This is his form during the beginning of the DIO's World story arc. In the anime, DIO's outfit is tinged orange, and his fingernails are very sharp and black.

He also has 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.

When pursuing the Joestar group, DIO donned a cloak that he discarded during his confrontation with Kakyoin.

Empowered
DIO nears his physical peak after draining Joseph Joestar's blood. His appearance now is similar to his revealed form, minus the jacket and the heart-shaped headband that was destroyed by Star Platinum's attacks. He now sports a deranged and homicidal look and mannerisms, having lost his suave touch. His hair is now disheveled and mostly oriented upwards, while his lips are darker and seem adorned with lipstick. This is his mien during the latter half of the DIO's World story arc, often called his 'High' or 'Awakened' form.
