I’m like 100 percent positive all of these boys are Asian and not white, this includes Hisoka. The show would make it obvious if a character is a certain race like white or asian, Black or Indian. A good like action would keep this in mind if they were to create Hunter Hunter.
I feel like “Vengeance” would be more fitting for Thomas Wayne’s Batman, and Bruce Wayne’s Batman would be more “Justice”. Bruce wanted to fix the world so no one else had to suffer like him, Thomas wanted to punish it for taking his son.
