Dio Brando. A very sly and cunning antagonist. Was adopted by
the Joestars, and decided to make an elaborate plan to kill
George Joestar and inherit all the fortune.
Can't really say more without spoiling
MAJOR plot points.
The Pillar men, Kars, Wamuu, Esidisi, and Santana are the last
of their species that are currently alive, and now they're the
main protagonists of part 2.
The pillar men are an ancient race of humanoid like people
with extreme power and intelligence. The only problem is that
they are vulnurable to the Sun and Hamon (Ripple), but they're
currently out trying to change that.
Dio Brando has now changed his name and evolved into DIO.
He's back for part 3, Stardust Crusaders.
I litterally cannot say more without bigger spoilers than
that.
This is Yoshikage Kira, otherwise known as Evil David
Bowie.
All he wants to do is live a quiet life. Unfortunatly he
can't due to some of his actions.
Diavolo is the Boss of the Italian Mafia and has managed
to keep his identity a secret for as long as he was in the
Italian Mafia.
