The Savage Land Mutates is a supervillain group appearing in American comic books published by Marvel Comics. Their creators were writer Roy Thomas and penciler Neal Adams. Within the comic books, the group is based in an imaginary place called the Savage Land, which is a hidden Antarctic environment inhabited by dinosaurs and primitive humans.

The Savage Land Mutates first appeared in The X-Men #62 (November 1969) and were created by Roy Thomas and Neal Adams.

The Savage Land Mutates were originally humanoid inhabitants of the Savage Land who were genetically altered by Magneto to serve as his troops.^[1][2][3] They clashed with the X-Men and Ka-Zar on multiple occasions. On one occasion, they turned Spider-Man into the Man-Spider and Angel into a bird monster. They have also encountered the Avengers. Although the group is fairly large, most appearances of the group contain only about half of the group's members, usually under leadership of Sauron, Brainchild, or Zaladane.^{[citation needed]}

During the "Secret Empire" storyline, Sauron returns to the Savage Land to claim leadership over the mutates. He ruled until Vertigo, Lupa, and Whiteout turned on him, driving him out of the Citadel. A resistance group of Avengers, searching for Cosmic Cube fragments, teamed up with Sauron to investigate, as they speculated that the mutates may have found it. The group was then ambushed by Gaza riding a Tyrannosaurus rex. He revealed that Sauron only kept the three female mutates at his side because they were desirable and not a threat to him. As the group arrived at the Citadel, Sauron attempted to betray them, but was quickly defeated by Mockingbird. She then bartered with Lupa, Vertigo, and Whiteout, offering to give them Sauron in exchange for the fragment. The trio refuse, as the fragment enabled them to overthrow Sauron and push the Savage Land towards peace. The two groups clashed, with Vertigo confronting Sauron with the knowledge that she had been cloned and killed many times. During the skirmish, Sauron managed to grab the shard but was defeated by the combined effort of both groups. Quicksilver then grabbed the shard and escaped. Lupa, Vertigo, and Whiteout allowed the group to leave in exchange for locking Sauron in a dungeon.^[4]

Amphibius later tells Sauron and the other Savage Land Mutates that Magneto's Asteroid M has risen from the sea, but they did not want to go find him. Worm took control of Barbarus, Lupo, and Sauron and commandeered a ship to go find Magneto. When threatened by the Japanese military, Sauron attacked an armored car, causing an international incident. Cannonball, Sunspot, and Warlock investigated and found the Savage Land Mutates on the deck of the ship. Cannonball fought Sauron in the skies while Karma discovered that the Savage Land Mutates were immune to her powers of psychic persuasion. Cannonball managed to defeat Sauron while the other New Mutants defeated the Savage Land Mutates. Upon learning why the Savage Land Mutates were on the ship, Karma told Worm, Sauron, Barbarus, and Lupo that they were in charge of Asteroid M and Magneto. Worm then orders the Savage Land Mutates to return to the Savage Land.^[5]
