>>44569611The world is explicitly styled after a diver, it has fucking scuba tanks, and references the hundred years Dio spent underwater plus "Holy Diver." The hearts that become a big part of Dio and his stand's look in part 3 are also possibly from the Dio album sacred heart. I don't know about color, but I'd probably pick guys like Cofagrigus, Gliscor, Crobat, Weavile, Dhelmise, Corviknight, or Klinklang for Dio.
