revolted. After a time of war, the animal people demanded civil rights and the Atlanteans used technology to expand the Savage Land's surface area for the animal people to live in. When the Great Cataclysm struck, the Atlantean empire fell and thanks to the machines, the Savage Land locations were spared from sinking into the sea. In more recent years, the Savage Land was rediscovered by Lord Robert Plunder, who took back a sample of the metal known as "anti-metal" or "Antarctic vibranium" with him. This mysterious metal had the ability to produce vibrations which would liquefy all other metals. Fleeing from those who sought to steal this discovery, Plunder took his eldest son Kevin with him for a second trip into the Savage Land. The elder Plunder was killed by a local tribe of Man-Apes. Kevin survived, thanks to the timely intervention of the orphaned sabretooth tiger later known as Zabu. He grew to adulthood in the Savage Land, becoming the adventurer known as Ka-Zar. Ka-Zar had many team-ups with the X-Men, who first revealed the Savage Land's existence, Spider-Man, and many other superheroes who had visited the Savage Land. He later met and married Shanna the She-Devil. The Savage Land's existence is common knowledge throughout the world. At one time, there were press junkets, sponsored by the oil company Roxxon. Daily Bugle photographer Peter Parker was sent and helped uncover Roxxon's unethical and dangerous manipulation of the local resources. At one point, Spider-Man teamed up with Ka-Zar to save Gwen Stacy from Kraven the Hunter and Gog at the time when her class and J. Jonah Jameson were visiting the Savage Land. Many villains have threatened the Savage Land, including Sauron, Garokk, Magneto, and Thanos. The Savage Land was decimated by an evil alien named Terminus (or one of his pawns) when he destroyed the machines that maintained the tropical climate. Many of the Savage Land's native people were saved from the ensuing destruction by M'rin: The Warlord of The Skies who took them into her own native dimension to safety. Ka-Zar, Shanna, and Zabu wandered until the High Evolutionary (with help from the X-Men, M'rin, and Garokk) restored the region and its creatures, allowing them to return to the Savage Land with their newborn son. The other natives who had taken refuge in M'rin's dimension returned as well. Sometime after that, Spider-Man had Devil Dinosaur and Moon-Boy
