Forced to drain the life force of others to sustain himself, Karl Lykos lives a miserable existence. If his victim happens to be a mutant, the drained force sets off a terrifying transformation.
Origin
Karl Lykos was the son of an explorer's guide. As a teenager, he accompanied his father to Tierra del Fuego as the elder Lykos guided a wealthy client named Mr. Anderssen and Anderssen's young daughter Tanya. While defending Tanya from mutant pterodactyls, Karl was bitten by one of the creatures. During his recovery, he discovered that he could now drain the life-force of other organisms. He found himself repeatedly tempted to use his new power, feeling that he needed to drain life energy from 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. He treated patients through hypnosis, but secretly robbed them of energy at the same time.
Dr. Lykos became a colleague of Professor Charles Xavier, and first encountered the X-Men when they sought treatment for Havok. When Lykos absorbed energy from Havok, there was a horrible side-effect: he transformed into a vampiric, pterodactyl-like monster with human intelligence and superhuman hypnotic powers. He named himself Sauron and battled the X-Men. But when he realized that his transformation would threaten Tanya, he fled to Tierra del Fuego. Without energy to absorb, Sauron turned back into Karl. When Tanya tracked him down, Karl threw himself off a cliff to avoid harming her. Presumed dead, Karl actually survived, merely unconscious on a ledge below. He journeyed to the Savage Land and survived in human form by only draining less developed animals. He befriended Ka-Zar and used his medical skills over many months to care for Ka-Zar's allies. But when several X-Men were stranded in the Savage Land, Lykos was overwhelmed with the desire to absorb the powerful life energy of mutants. He transformed into Sauron once again after absorbing Storm 's energy. He reverted back to human form during a battle with the X-Men, and Ka-Zar explained that Lykos was an ally.A notable appearance was in the first story arc of the series Marvel Fanfare (1982), written by Chris Claremont. In that story, 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. Unfortunately, he had reverted to his Sauron form and joined the Savage Land Mutates. The X-Men traveled to the Savage Land and defeated Sauron and the Mutates. They brought Lykos back to the United States, and at the X-Mansion Professor X seemingly cured Lykos of his condition. Karl and Tanya decided to resume their relationship and a normal life.
Brotherhood
Weapon X
Sauron became a prisoner of the recent Weapon X program jumpstarted by director Malcolm Colcord. Being held there against his will, Sauron started up a revolution with fellow agent Brent Jackson and dethroned Colcord as director, giving that position to Jackson. Sauron in return became a more powerful villain on the team, but vanished after Weapon X rival John Sublime launched an attack on Weapon X, and the group had to go underground.
Attack on the New Avengers
Sauron held the new team of Avengers hostage when they came to the Savage Land; his colleagues had recently hired Electro to break him out of the supervillain prison he'd been sent to, and the New Avengers had gone to the Savage Land to confront him about the forty-one other escapees. The team freed itself thanks to Iron Man's voice-activated armour, and were about to interrogate him, when he was shot through the head by the Black Widow. Fortunately for Sauron, he had absorbed Wolverine 's regenerative healing factor and recovered from his injury, just in time to be soundly defeated by the New Avengers. He was taken back into custody, but not before returning the favor to Black Widow by burning her with his fiery breath. He was apparently returned to the custody of Weapon X.
Powers
In his human form Karl Lykos is fairly typical, except he keeps his ability to absorb the life forces of other living things to sustain himself. This often triggers his transformation into his pterodactyl form. If he absorbs the life force of a mutant he will absorb a portion of their powers temporarily. Due to manipulation by the Weapon X program, Sauron can expel the life force energy in concussive bursts from his hands.
In the pterodactyl form he is superhumanly strong and possesses the ability to fly at a natural winged flight limit. In battle Sauron has several additional weapons a lethal beak and sharp talons on his hands and feet.
At some point in time prior to his New Avengers appearances he acquired an additional ability to breathe fire which he used to burn the second Black Widow in revenge for shooting him.
He also has a powerful hypnotic ability that requires direct eye contact to complete. He frequently uses his hypnotic power to give his victims terrifying delusions that allies have become monsters.
