Diego Brando From Another Worldo

Diego "Dio" Brando is a racer in the Steel Ball Run and serves as an antagonist of the series. He is the alternate universe counterpart of Dio Brando, the most featured antagonist in the previous series.

Diego "Dio" Brando
During the 8th round, Diego turned against Valentine. But he was quickly defeated by his stand, Dirty Deeds Done Dirt Cheap, and had his Turbo eye taken away from him.

Supposed Past
Diego's parents were financially weak and disposed of him as a baby – however, his mother felt guilt and risked her own life to save him from drowning, upon which his alcoholic father left them both. His mother changed her surname to "Brando" and got employed by a farm, but she and Diego lived in poverty in the stables. Five years later the man that had arranged her employment demanded sexual favors from her, and upon her refusal, sabotaged their means to get food. Another year later his young mother died of the tetanus infection, which Diego (at the time 6 years old) believes to be a result from the humiliation they had to suffer. The boy grew up resenting everyone who abandoned them and swore to himself to get revenge against the man who had harassed his mother.

No matter how hard the times he and his mother fell on, she refused to discard of what little dignity they had left – she taught him that eating out of shoes due to lack of proper dishes was unacceptable. Partly from her example, Diego developed a strong sense of pride.

The World
In recently chapters of Steel Ball Run, Funny Valentine summoned "Diego Brando" from another dimension.This Diego revealed the ability of timestop of the world, as the stand as well. The "new" Diego appeared to be more sadist than the original Diego trying to kill Johnny with very violent ways as throwing knives or trying to burn Johnny alive with matches.

Trivia
Some resemblances to the Dio of previous JJBA parts include:
 * He has a liking to coffee.
 * He has been good with horses since he was a child, even untamable ones let themselves be handled him.
 * His 5-year old self much resembles Giorno.
 * A fondness towards his mother (likely the only person he truly respects) and an alcoholic father.
 * A rise to fame with a cold-hearted attitude, in both stories he had no scruples in his actions to reach the top.
 * He married a woman of considerable age who fell in love with him – most likely a reference to Enya Geil (OVA) who died like the unnamed woman by his hand.
 * The same Stand as the original Dio and the same sadistic technique as well.
