A normal human by the surname Brando who trancended humanity. Dio put an ancient stone mask over his face and stabbed his rival Jonathan Joestar's father, dowsing the mask in blood and causing its bones to impale his skull, awaking the brain's hidden abilities. By doing so, he became a vampire with numerous powers.
Dio Brando is the main villain of JoJo's Bizarre Adventure Part 1, and comes back stronger than ever in Part 3.
