Yeah, if you ever check out the comic that JoJo's based on, the villains are all vampires...Except they don't use their fangs to suck blood, but rather tubes/veins from the fingers... The comic sure lives up to its name. eek!
Now I remember they made animation based on it, which I am currently searching for...
Oh, and my japanese friends once informed me that the artist stopped drawing the comic in the seventies, but then later returned to continue it in the nineties, which the games were based on. If anyone here knows more about this great comic, please contact me!
