Diego Brando's Mother

Dio Brando's mother (ディオの母) is a minor, fictional character referred in the manga JoJo's Bizarre Adventure by Hirohiko Araki. Her name remains unknown.

History
Little is known about her, only that she was a poor woman married with Dario Brando. She appeared to be the only person Dio Brando ever cared for, as he mentions his hatred for his father due to having made her suffer and "working her to death."

Steel Ball Run
Dio's Mother lived in an impoverished region on the island of Britain with her husband. At some point in time, they had Diego, but were forced to dispose of him due to their poverty-stricken lives. Once it became night, the two went up into the mountains and dug a holet with intent of burying the child. After wrapping Diego in a white cloth, they placed him in the hole and left. Soon after, a storm occurred and the water in the river increased and started a flood. The flood caused some type of erosion and the baby was submerged from the ground and forced downstream. Dio's mother had a change of heart and dove into the river after her baby.

After the rained had stopped, she was found unconscious by a man who was employed at a farm. Dio's Mother began working on the farm and changed her surname to Brando. She raised Diego on that same farm, and after he was old enough, the two worked from dusk to dawn and were given a place to sleep, and a small amount of food. 5 years later, Dio's Mother was harassed by the same farmer who saved her, claiming it was recompense for her life. She declined, but in return the farmer punctured two holes in both Diego and her mother's soup bowls, rendering them useless. Dio's mother was forced to receive their portions on her hands, despite the soup being scalding hot.

A year later, Dio's mother caught a disease called Tetanus and died at the young age of 23. Before taking her last breath, she said to Diego that it was not his fault and that he should use his talent with horses to become a jockey. Diego believed that the germs that came in through his mother's burns were the cause of her disease and intuitively knew that the farmer was the cause of her death. It was revenge towards the farmer and the other people on the farm who looked down on them that fueled Dio's goal of rising to the top of society and entering the Steel Ball Run to gain complete influence over all, including the Royal Family of England.
