Dio Brando

"WRRRRYYYYYYYYYYYYYYYYYYYYYYYYYYY!!"

- Dio Brando's battle cry

Dio Brando (ディオ・ブランドー, Dio Burandō), also known as "DIO" from Part 3 onward, is the main antagonist of Part I: Phantom Blood and Part III: Stardust Crusaders, though his legacy causes repercussions throughout the rest of the series as well. He is also the father of part 5's protagonist Giorno Giovanna.

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 appears to have 3 dots on the lobule of his left ear, which seems to be a birthmark.

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

Reborn Vampire form
Dio's clothing has changed quite a bit after his first battle with Jonathan; Most noticeable is the scarf around his neck. He wears an ornate shirt and breeches, a large pair of boots, vambraces, and two suspenders attached to a band around his waist.

Shadow form
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 (of which his head is sewn in place) and wears green pants with suspenders, gray clogs, black shiny cuffs on both wrists and 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 writers to add mystery). This form of Dio is also called "Jyaaku no Kenshin Dio." (Dio the Evil Incarnate)

Fuku form
Just like the Shadow form, only his entire suit is now colored yellow. Dio's face is seen, his hair is blond, wearing a jacket with a tank-top underneath. He now also wears a heart-shaped circlet, and rings for his cuffs. This is his form during the beginning of the Dio's World story arc.

Enraged/Armored form
Dio transforming into his ultimate form, after sucking Joseph Joestar's blood. The description is like his fuku form minus the jacket and the heart-shaped hairband (which had been destroyed during Star Platinum's attacks). He now sports a deranged and homicidal look and mannerisms, losing his cool touch, and his hair is now disheveled, mostly oriented upwards. This is his form during the latter half of the Dio's World story arc.
