The biggest mafia stands among people, higher than the presidents, higher than the rich. The Skullz have a hierarchy within their mafia. Diamond, Golden, Metal, and Copper. Diamond represents a place higher than Golden, and Golden represents Alpha. Metal and Copper represent Beta and Omega. Everybody within the Skullz are forbidden to take off their skull mask. Each mask comes with its own unique feature that stands out among the rest, animals resembling the skulls.
