Brando Family

The Brando Family (ブランドー家) is a dynasty of characters mainly featured in the first seven parts of the JoJo's Bizarre Adventure series that are connected to the supernatural and the Joestar Family.

Summary
The Brando Family has very few known members, mostly due to one generation being frozen for a century when Dio Brando was trapped at the bottom of the ocean. Thanks to Dio grafting his head to Jonathan's body, the Brando family is deeply connected to the Joestars, and his bastard sons can be said to be both descendants of Dio and Jonathan, all bearing the Star Birthmark. With the exception of Giorno Giovanna, all Brandos have been antagonists to the Joestars.

Their known history begins in the 19th Century as a family of poor Londoners living in squalor. The father, Dario Brando, was a thief who abused his family, eventually leading to his wife's death and contributing to making his son Dio Brando a worse person. One night, Dario was mistaken for trying to save the Joestar family after a fatal carriage accident by George Joestar I when he was actually trying to rob them. George felt indebted and eventually adopted Dio in his family after Dario's passing. Dio took this opportunity and tried to inherit the Joestar family wealth, by distancing Jonathan from their father and even going so far as to poison George. Thus began a generation spanning feud between Dio and the Joestar family. Dio used the Stone Mask to become a vampire and surrounded himself with Zombies and kill Jonathan only to be sealed at the bottom of the sea. A hundred years later, DIO gathered malevolent Stand users. Jonathan's descendants continued fighting Dio, finally defeating him in Cairo, Egypt.

Before his defeat but after awakening from being trapped in the ocean, DIO had at least four children, being Giorno Giovanna, Donatello Versus, Rikiel, and Ungalo. After DIO's death, his children found themselves in many different situations and social standings. Giorno becomes very successful in achieving his goals while his known half brothers had much worse lives.

Brando Family (Second Continuity)
In the Steel Ball Run continuity, the few known Brandos regain their origin as a poor and destitute family with a tragic streak.

Left for dead, Diego and his mother changed their surname to Brando and lived as farm workers who were abused. Diego eventually becomes a renowned jockey with a foot on British nobility by virtue of marrying a rich old woman and inheriting her wealth and status. This family has far fewer ties to the Joestars, as Diego only temporarily worked in the Joestar's stables, and was a mere rival to Johnny among others during the Steel Ball Run.

The family line effectively ended when Diego was killed while battling Funny Valentine.
