Dio Brando/Personality and Relationships

Personality
"Can a monkey reach a human? You are but a monkey, Jojo!"

- Dio, to Jonathan

Dio is ambitious, narcissistic, arrogant and megalomaniac, and will do anything to get what he wants. He frequently bullied and upstaged Jonathan Joestar in their youth in order to place himself in a better position to replace him and obtain the Joestar family fortune, and in his adulthood, relinquished his humanity in favor of becoming a vampire.

However, Dio is not entirely evil, although he tends to approach it. He shows a good side to those who are good to him. In particular, he has shown favorable attitudes towards Enrico Pucci, who also showed loyalty in return. This trait is particularly emphasized in the anime, when Dio is shown to have killed his own father out of revenge for the abuse against his mother, rather than as a step in his scheme to rise in society. Dio also has a passion for reading, as he is found in the library of his Egypt mansion several times he is shown.

Unless provoked or deemed an obstacle, Dio will normally not attack anything or anybody (although probably more out of regarding them as inconsequential, and so not worthy of attention, than anything akin to kindness). He will first try persuading people to work for him, then fight them, if they oppose.

It is implied in Part VI: Stone Ocean that Dio wanted to use his stand to create a perfect world for himself and a handful of subordinates. He enlisted Pucci as his living "conscience", in case he would go crazy and veer "off track".

Family

 * Dario Brando : Dio hated his father and saw him only as a stepping stone in his path to ascend in society. In the anime, Dio's hatred stems from the abuse he dealt his mother with his alcoholism, as well as himself. He emphasizes this by spitting on his grave before leaving for the Joestar mansion.
 * Giorno Giovanna: Dio is not shown to have interacted with Giorno, although Giorno keeps a photo of his father in his wallet. Also to note is that while Dio was shown to have sucked the blood out of young women, killing them in the process, he had neglected to kill Giorno's mother for unknown reasons.
