While on an expedition to Tierra del Fuego, geneticist/psychologist Dr. Karl Lykos was bitten by a mutated pterodactyl from the prehistoric Savage Land which infected him with a genetic virus that forced upon him the need to drain the life energy of others to survive. Lykos eventually became a hypnotherapist, and constructed a device to help drain his patients’ energies. After absorbing the energy of the mutant Havok, Lykos was transformed for the first time into the pterodactyl-like Sauron, named after the arch-villain of Tolkien’s The Lord of the Rings novels. He battled the X-Men, but soon began reverting back to Lykos and fled. Later, as Sauron, he attempted to kill his own lover Tanya Andersson, but was again opposed by the X-Men. As Lykos, he became despondent over his behavior, and after she and the X-Men found him he ran over a precipice and was believed dead.
