JoJo's Bizarre Adventure - TFW you're a vampire

For all we know, Arabia Fats had a complex backstory and it made complete and total sense why a sun stand user would work for Dio. Too bad he never got the chance to say a word because Jotaro had to be all a punk.

It should be remembered that despite spending all that time in The Sun's light, none of the crusaders had sunburns. Arabia Fats' Stand probably doesn't give off UV light.
