In Ancient Alabama, the priests work to keep the Gray Diamond from falling into the hands of Lord Diamond which ends with the pyramid being destroyed. Upon not having a catchphrase or any powers, Gray Diamond leaves Axe Cop's team and pawns the Gray Diamond on top of his head at a pawn shop. Taking advantage of this, the mummy of Lord Diamond from the Museum's Ancient Alabama exhibit claims the Gray Diamond and starts using it's powers to drain the souls out of everyone in the city. Now it's up to Gray Diamond to save Axe Cop and defeat Lord Diamond.
