other humans or animals to survive. When Karl's father died, Mr. Anderssen took Karl into his home in thanks for rescuing Tanya. As the years passed, Karl and Tanya fell in love, but Tanya's wealthy father would not allow her to date Karl because of his lack of wealth. In an effort to win Mr. Anderssen's support, Karl went to medical school and became a physician, geneticist, and hypnotherapist. He treated patients through hypnosis, but secretly robbed them of energy at the same time. First transformation into Sauron and life in the Savage Land Dr. Lykos became a colleague of Professor Charles Xavier, and first encountered the X-Men when they sought treatment for Havok. Absorbing Havok's mutant energy transformed him into a vampiric, pterodactyl-like monster with human intelligence and superhuman hypnotic powers. He named himself Sauron, after J.R.R. Tolkien's villain (also reminiscent of the word saurus, Latin for lizard), and battled the X-Men, as a would-be conqueror.

He transformed into Sauron once again after absorbing Storm's energy. He reverted to human form during a battle with the X-Men, and Ka-Zar explained that Lykos was an ally. Tanya learned that Karl had survived the leap from the cliff. She joined Angel and Peter Parker on a journey to find Karl in the Savage Land. They found Karl, however the Savage Land Mutates used a Genetic Transformer to mutate Angel, Spider-Man and Tanya into animal-like forms. The destruction of the machine forced Lykos to drain energy from the three in an attempt to restore their true forms. Although his gambit succeeded, he subsequently reverted to his Sauron form and joined the Mutates and Zaladane. The X-Men traveled to the Savage Land, and Sauron helped to capture them. However, the X-Men escaped and defeated Sauron
