Back in the dark caves of Hollow Earth, Camazotz continued to sleep. That lasted until 2021, when the permanent superstorm Ghidorah had left behind in the Pacific Ocean moved over Skull Island. It merged with the storm barrier around the island, forming a new superstorm.
At that moment, an earthquake suddenly struck Skull Island, waking the slumbering Camazotz. He descended upon the island once more, leading an army of bats into battle against Kong. Monarch also sent fighter jets to assist.
After a grueling battle, Kong drove Camazotz back into Hollow Earth and won the fight.
Unfortunately, the superstorm also dealt a devastating blow to Skull Island's ecosystem. That was why Monarch planned to move Kong into Hollow Earth.
