—Diego's signature battle cry, also used by his children in Stardust Crusaders, PB, BT & SDC
Diego is a somewhat tall boy of average build and with blond hair, his eyes are blue, but when he becomes a vampire, they turn red, he also gains long fangs.
Diego wears a cyan sweater with a yellow diagonal grid pattern, his hat is the same cyan color as his sweater and has the name "DIO" written on it in yellow. His pants are brown denims with a leather belt.
As a vampire, Diego wears a long dark blue coat with a feathered collar and shoulders with the same shirt and pants underneath
When Diego is revived by Dean Napalm's life power in the end of Battle Tendency, he appears the same as his vampire version in the previous part, only the skin in half his face is missing and his clothes are discolored and ripped up.
Diego has always been a hateful person, to his father, his friends and especially to the Joestars after Jorge disfigured him in their final battle in Phantom Blood, but Diego also has a lighter, jokester side, but it very rarely shows up.
Diego, despite being a bad kid, is very well behaved, even better than Jorge, who grew up in a rich family.
Diego has a love for many different animals, but his favourite type of animal is felines, such as lions, tigers and especially household cats.
Diego was born on January 15th, 1876, in a rather poor district of London, ever since he was five, he was raised only by his drunken father, Dario Brando, who constantly harmed Diego, mainly by throwing empty beer bottles at him.
