Dr. Karl Lykos aka Sauron was a brilliant Argentinian hypnotherapist.[1] He also became a human-Pteranodon hybrid and would-be-conqueror of the "Savage Land", a hidden refuge for Dinosaurs nestled in the modern Antarctic.[6] As a child he was attacked by a mutated Pteranodon and somehow became an energy vampire, forced to absorb the life energy from animals and humans to survive. By absorbing the life energy of a Mutant, he transformed into his savage alter-ego; "Sauron".[7]
