De La Porta takes the Primal Stones from an ancient temple on Kong Island, which upsets the Island's mystic and environmental balance. Earthquakes, storms, and volcanoes shake the Island. They find the Professor, but De La Porta merges with a giant prehistoric cave snake. Kong goes head to the head with the newly created monster, but is buried in a cave-in. Drawing on his memories, he finds the strength to slowly free himself. De La Porta attempts to leave the Island in a seaplane, but Jason, Tann, and Lua battle him until Kong arrives to help. De La Porta eventually escapes with 6 of the 12 Primal Stones. Jason vows to hunt him down and retrieve the Stones.
