Cobra (Marvel Comics)

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 "King Cobra". He first appeared in Journey into Mystery #98 (Nov 1963) created by writer Stan Lee and artist Don Heck. His nephew, Piet Voorhees, took over the name "Cobra" and first appeared in White Tiger #1 (Jan 2007) in a story written by Tamora Pierce and drawn by Timothy Liebe. Marvel has also used the moniker "Cobra" for two World War II Nazi villains and also a mercenary enemy of Moon Knight.

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. 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 Viper, Cobra actually opposed her rule and sided with Captain America to depose Viper and foiling her plans. Cobra later took the name "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) King Cobra became a member of the group.

Piet Voorhees, nephew of Klaus Voorhees, was injected with the same chemicals that gave Klaus his powers and he became the new Cobra and worked as a mercenary. On one mission he encountered the White Tiger who defeated him. Cobra later joined the Serpent Squad, organized by Sin and would also work for HYDRA as a mercenary.

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.

Klaus Voorhees was born in Rotterdam, the Netherlands. Klaus was an ex-convict and the Dutch laboratory assistant to Professor Schecktor, a scientist working in India and looking for a cure to snake bites. Unsatisfied with his lower condition, and intent on stealing Schecktor's discoveries, Voorhees killed the professor by using a cobra and in order to make himself look less guilty, let the cobra bite him as well. He used an experimental anti-toxin for snake venom to cure himself, but denied it to Schecktor. The cobra was radioactive due to experimentation, and in a process similar to that which granted Spider-Man his powers, Voorhees gained superhuman abilities similar to a cobra's. Thor's mortal form, Don Blake, had encountered Schecktor and, as Thor, he met the dying man and learned what had happened, and that the Cobra was travelling to America. The Cobra attempted to manufacture a cobra-serum to transform others into similarly-powered slaves, but was thwarted by Thor although he escaped, using Jane Foster as a hostage.[1]

As the professional criminal called the Cobra, he fought Thor and Daredevil, and a number of other superheroes. Mister Hyde and the Cobra were partners for years. They first joined forces to get revenge upon Thor, but were jailed.[2] Cobra and Hyde were then bailed out and employed by Loki to kidnap Jane Foster, and Loki doubled their powers. Thor followed them to a house where traps had been set up for him. Hyde was defeated and Thor then manipulated the power supply of the house. Using his hammer, he sent a charge through the house that electrocuted the Cobra. The weakened Cobra was forced out of a pipe next to Thor. He was easily defeated by Thor and left bound, before being arrested with Hyde.[3] Cobra then battled Daredevil for the first time.[4] He later teamed with the Jester and Hyde against Daredevil.[5]

Cobra later joined the original Serpent Squad with the Eel and the Viper. With the Serpent Squad, he attacked Captain America and the Falcon.[6] He subsequently joined the second Serpent Squad, and battled Steve Rogers in his Nomad identity, then he became involved in an attempt to raise the continent of Lemuria.[7] He became trapped with the second Viper, and his cowardice earned her enmity.[8]

Later, he assisted Hyde in an attempt to acquire Cagliostro's serum.[9] The Purple Man then mind-controlled him, and Cobra fought Daredevil in an arena alongside Hyde, the Jester, and the Gladiator, whose minds were also controlled by the Purple Man.[10] Later, Cobra refused to take Hyde along on a jailbreak, effectively ending their partnership, and Cobra got into a battle with Spider-Man.[11]Hyde then began stalking his former partner.[12]

Cobra then joined Sidewinder's Serpent Society crime cartel.[13] He teamed with Diamondback to locate the Scourge.[14] Later, he went on a mission to poison Washington D.C.'s water supply.[15] He also helped Captain America subdue the Viper.[16] When Sidewinder retired, the Cobra became the leader of the Serpent Society.[17] He beat Mister Hyde in personal combat, and then assumed a new costume and the name "King Cobra."[18] He later sentenced Diamondback for treason to the Society.[19] He still leads the Society (complete with a new Sidewinder), though he also partners with Mister Hyde on occasion.

King Cobra was later summoned by Zarrko to fight the Thor Corps. Upon arriving he attacked Dargo Ktor, a future version of Thor, before he tosses him to Tyrus the Terrible.[20]

King Cobra was enlisted by Lucia von Bardas, the former prime minister of Latveria and placed in her secret army of technology-based villains. She sent the army against Wolverine, Spider-Man, Luke Cage, Daredevil, and Captain America, the five heroes Nick Fury had sent to Latveria to stop Lucia's secret criminal funding. When the battle started to turn in favor of the heroes, Lucia turned all the armor of her technology army into a bomb. Nick's unknown agent Daisy defeated her and the armor army's lives were saved. Klaus escaped the heroes in the resulting battle between Nick Fury and Wolverine.

After passing of the Superhuman Registration Act in the Civil War storyline, he was forced to join the Thunderbolts and be trained by Swordsman, along with the Ox and the Unicorn.[21]

In spite of this, King Cobra, Firebrand, Mauler, and Mister Hyde, attacked Yellowjacket, Constrictor and other Initiative staff and trainees.[22]

King Cobra was with the Serpent Society when they were robbing banks.[23] King Cobra and the Serpent Society were defeated by Hope Summers.[24]

Piet Voorhees is the nephew of Klaus Voorhees. Klaus injected Piet with the same mutagenic serum that first gave him his own superhuman abilities. Using these new powers for selfish means, Piet became a high-level international mercenary. He has performed operations in Southeast Asia, Bosnia, Central Asia and Chechnya.

More recently, Cobra has become involved with an international cartel known as Chaeyi. He has been working to get stolen passports and visas to illegal aliens. This operation has brought him into conflict with the newest White Tiger.

In a new costume, he has since turned up as a member of Sin's new Serpent Squad, in the employ of the Red Skull. He breaks Crossbones out of jail[25] and later attacked the White House, but he was stopped by the new Captain America. Cobra escaped with Sin in a helicopter and reported the incident to Red Skull.[26][27]

Cobra later appears as a member of HYDRA led by Baron Zemo, who are planning to spread poisonous blood extracted from an Inhuman boy named Lucas. He and Armadillo later fight Sam Wilson, the new Captain America, until Armadillo is convinced to turn on HYDRA and stops Cobra from killing Sam Wilson.[28]

As part of the "All-New, All-Different Marvel", Cobra appears as a member of Viper's Serpent Society under its new name of Serpent Solutions.[29]

During the "Opening Salvo" part of the "Secret Empire" storyline, Cobra was with Serpent Solutions when they are recruited by Baron Helmut Zemo to join the Army of Evil.[30]

In the prelude to "Hunted," Cobra was among the animal-themed characters that were captured by Taskmaster and Black Ant on Kraven the Hunter's behalf. He was grouped with Rhino, Scorpion, Stegron the Dinosaur Man, Tarantula, and Vulture as the Savage Six by Arcade. In this appearance, Cobra was identified by Arcade as "King Cobra."[31]

Powers and abilitiesEdit

Klaus Voorhees gained superhuman powers due to the mutagenic effects of the venom of a radioactive cobra plus an experimental antidote. Cobra is double-jointed, and can dislocate and snap back into place his shoulders and hips at will, and has a phenomenal mastery of his musculature. Most notably his amazing contortionist powers and slithery body let him break in, and escape from, buildings. He also has the ability to stick to walls or ceilings. Combined with his superstrength, agility, reflexes and reactions, coordination, balance, and endurance, they make him a formidable wrestler. King Cobra's bones are flexible and nearly impossible to break. King Cobra has moderate knowledge of street-fighting techniques. King Cobra wears a bodysuit made of reinforced synthetic stretch material; the torso section, helmet, and tail were made of bendable plastoid, and the entire costume is coated with silicon and graphite dust compound to make it slippery. King Cobra is also armed with special gadgets that complete his cobra likeness: he is equipped with a "cobra cord" (an unbreakable cable) to tie up his enemies (solid enough to resist Thor's strength), can launch "cobra darts" (venom-filled projectiles) out of his wrists and release toxic "cobra gas". He wears spring-loaded wrist-shooters propelling "cobra-bite" projectiles containing a poison derived from cobra venom. He uses cartridge projectiles filled with various substances: acids, smoke, nerve gas, plastic explosives, etc. He wears micro-suction cups on his fingertips and toes permitting him to cling to walls and ceilings. In the miniseries Toxin: The Devil You Know, King Cobra himself quotes:

My bones are almost impossible to break. My tissue doesn't tear. I don't get hangovers, either.

Piet Voorhees possesses certain unusual physical powers derived from his mutagenically altered physiology which, among other things, help him simulate the movement of a snake by using his great degree of independent control over every muscle in his body, enabling him to slither across the ground (at up to 50 miles per hour) without using his arms and legs, simply by muscle contraction. 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.[32]Cobra's flexibility enables him to slither into and out of very tight and small places. Through compressing his body, Cobra can fit into any hole or slot down to four inches (102 mm) in diameter. By using his flexibility to wrap himself about a victim's body and then exerting his full strength, Cobra traps that victim within his "cobra grip". Unlike his uncle, however, Piet also possesses enhanced olfactory senses, which enables him to track his targets by way of scent. He can also produce a toxic substance from his body which he calls his "cobra venom". He projects his venom at selected targets by spitting at them.

James LardnerEdit

A few months after his brother Amos Lardner disappeared, James Lardner joined the CIA where he met Marc Spector a.k.a. Moon Knight. When Marc asked about James' brother Amos, James never talked about him. Three years later, James sought vengeance upon those who were involved with Operation: Cobra. Upon blaming Marc Spector, he launched a grenade at Marc's mansion, yet Marc survived. James later launched a grenade at Ravencrag Asylum. Meanwhile, Marc received Amos Lardner's corpse and went to Ravencrag to see if there was a connection. Marc Spector was present when James Lardner attacked. Marc changed into Moon Knight and went after James Lardner who used a gas grenade to escape. When in Paris, James went after Charles LeBlanc who was the head of Operation: Cobra. Marc Spector also investigated Charles LeBlanc and encountered James Lardner. Marc Spector pursued James Lardner in a high-speed chase, where they were knocked unconscious upon colliding. The agents that worked for Operation: Cobra managed to capture James and Marc, only for Marc to escape. James, however, became the successful test subject that was dubbed Cobra. The next night when Moon Knight went to investigate Charles LeBlanc, Operation: Cobra sent Cobra to dispose of Moon Knight. Moon Knight had a hard time fighting off Cobra, until he spotted Charles LeBlanc using his remote control and shot a dart at it. The dart shorted out the remote control, causing Cobra to go berserk. Charles LeBlanc escaped to his car and started to drive off, only for Moon Knight to fire another dart at one of the tires, which caused the car to swerve and catch on fire upon colliding with a tree. When Cobra wanted to seek vengeance and started to lift the front part of Charles LeBlanc's car into the air, it exploded enough to kill Cobra and Charles LeBlanc.[35]
