- "Everything is set. The troops are in position in the city as we speak. Give the word, and we will unleash chaos."
- ―King Cobra to Sin
Klaus Voorhees, better known as King Cobra, is the leader of the Serpent Society.
As a reformed ex-convict, Klaus Voorhees became the lab assistant to the renowned medical researcher Ezekiel Shecktor. At the side of the scientist, Voorhees learned a great deal about serpents and chemistry while growing increasingly envious of his professor. At the peak of his jealousy, Voorhees used an irradiated cobra to poison and kill Shecktor. To mask his crime, Voorhees allowed the cobra to bite him as well, but used an experimental anti-toxin to counteract the venom. As a result, Voorhees gained powers similar to those of a cobra. Voorhees became King Cobra, the leader of the Serpent Society.
War Against S.H.I.E.L.D.
King Cobra allied himself with Sin and the Taskmaster in their conflict against S.H.I.E.L.D.. Once they had prepared Stage One of their plan, he informed Sin that their troops were in position in New York City, and that they would unleash chaos on her orders. He also warned her that Captain America would not give in so easily.
After Taskmaster was defeated by Captain America and taken into S.H.I.E.L.D. custody, Sin informed King Cobra of this and insisted that others needed to be sent to take care of Rogers. Cobra replied that he had friends who were looking forward to crushing the life out of him. He sent U.L.T.I.M.A.T.U.M. to team up with R.A.I.D. in Washington, D.C. and increase pressure on S.H.I.E.L.D., beginning Stage Two.
Cobra sent Serpent Society troops led by his subordinate Puff Adder to attack Washington, D.C. and distract S.H.I.E.L.D. while their troops moved stolen Iso-8 warheads from the R.A.I.D. base there.
