Quote1 I've been bitten by a radioactive cobra??!! Quote2
-- Klaus Voorhees src 
Cobra 002

Klaus Voorhees was an ex-convict working with the humanitarian medical researcher Professor Ezekiel Shecktor in India on a universal anti-toxin for snake venom. Jealous of Shecktor's success, Voorhees plotted to kill him and make the murder look like an accident.

Hence, Voorhees induced one of the cobras kept in the laboratory to bite both Shecktor and himself. Voorhees planned to use the universal anti-toxin to save himself from death. Unknown to Voorhees, the cobra had been irradiated. The combination of the radioactive venom in his bloodstream and the experimental anti-toxin which he used created a mutagenic catalyst which gave Voorhees certain cobra-like powers.

Assuming the costumed guise of the Cobra, Voorhees used his new found superhuman abilities for crime, but was eventually thwarted by the Asgardian thunder god Thor.[1] Soon thereafter the Cobra began his longtime partnership with another of Thor's adversaries, Mister Hyde. But the team of the Cobra and Mister Hyde were defeated repeatedly, first by Thor[2][3] and later by the costumed crimefighter Daredevil. Hyde and Cobra were among the many costumed menaces assembled by Doctor Doom to disrupt the wedding of Reed Richards and Susan Storm[4].

Acting independently of Hyde, the Cobra served as a member of the first and second Serpent Squads. The Cobra came to believe that his criminal career would fare more successfully if he no longer acted in partnership with Hyde. Hence, when the Cobra made an escape from prison on Ryker's Island in New York, he refused to free Hyde, who was also imprisoned there, despite Hyde's pleas. Infuriated, Hyde vowed vengeance and has since made attempts on the Cobra's life.

After operating independently for a time, Voorhees accepted an invitation to join the Serpent Society and changed his codename to King Cobra when he became the leader of the criminal organization.

He has passed the King Cobra identity on to his nephew Piet Vorhees.

Powers and AbilitiesEdit


Elasticity: King Cobra possesses certain unusual physical powers derived from his mutagenically altered physiology which among other things help him simulate the movement of a snake. All of the bones in his body, including his skull, are malleable and his muscle tissue is exceedingly resilient, making his body very flexible and pliant. It is nearly impossible for him to break a bone or tear a muscle. Hence, the Cobra can survive impacts that would kill or inflict major injury upon a normal human being with little or no injury to himself.

The Cobra's flexibility enables him to slither into and out of very tight and small places. Through compressing his body, the Cobra can fit into any hole or slot down to four inches in diameter.

By using his flexibility to wrap himself about a victim's body and then exerting his full strength, the Cobra traps that victim within his "Cobra Grip." No normal human being can break free of his grip unless he or she is extraordinarily well trained in fighting, and even many superhumanly strong beings would have difficulty freeing themselves.

The Cobra has a great degree of independent control over every muscle in his body, enabling him to slither across the ground, without using his arms and legs, simply by muscle contraction. He is extremely quick, capable of moving up to 50 miles per hour for several seconds by this method. His agility and speed make him very difficult to catch and hold onto.

King Cobra has developed a number of special weapons to enhance his cobra-like powers. His costume is specially treated with a silicon and graphite-dust compound, making it extremely slippery. He has also designed special chemical suction devices for his fingers and feel, enabling him to stick to walls and ceilings. In the compartment behind his articulated chest armor is a fifty-foot long coil of steel cable that can be shot by means of a powerful spring.

From his spring-loaded device the Cobra can shoot a number of deadly projectiles. His "cobra-bite" missiles contain cobra venom. The venom from a single such missile can kill average-size, normal human being in six minutes. It takes more than one venom-filled missile to have the same effect on a superhumanly strong human being. The Cobra has also used projectiles carrying smoke, nerve gas, and a special substance that induces temporary blindness.
