The Cobra is the name of a number of different fictional characters appearing in American comic books published by Marvel Comics. The most well-known Cobra is Klaus Voorhees, now known as the King Cobra. He first appeared in Journey into Mystery #98 (Nov. 1963) created by writer Stan Lee and artist Don Heck. Klaus Voorhees was a laboratory assistant, working with a professor trying to find a cure for various venomous snake bites. A combination of a bite from a radioactive cobra and the experimental anti-venom granted him superpowers, which led to him becoming the supervillain briefly known as the Human Cobra and then as the Cobra. The Cobra and Mister Hyde formed a criminal team for years, fighting various heroes such as Thor and Daredevil. He later became a member of the Serpent Squad and a member of Sidewinder's Serpent Society. During a takeover attempt by the Viper, the Cobra actually opposed her rule and sided with Captain America to depose the Viper and foil her plans. The Cobra later took the name "the King Cobra" as he assumed leadership of the Serpent Society. When the Serpent Society became Serpent Solutions under the leadership of the Viper (Jordan Stryke, a different Viper) the King Cobra became a member of the group. His nephew, Piet Voorhees, became the second Cobra and first appeared in White Tiger #1 (Jan. 2007) in a story written by Tamora Pierce and drawn by Timothy Liebe. Piet Voorhees was injected with the same chemicals that gave his uncle his powers and he became the second Cobra, working as a mercenary. On one mission he encountered the White Tiger, who defeated him. The Cobra later joined the Serpent Squad, organized by Sin and would also work for HYDRA as a mercenary. Marvel has also used the moniker "Cobra" for two World War II Nazi villains and also a mercenary enemy of Moon Knight. The original Cobra has appeared outside of Marvel Comics, most notably in "The Mighty Thor" portion of The Marvel Super Heroes as well as in episodes of The Avengers: Earth's Mightiest Heroes and Marvel Disk Wars: The Avengers.
