They faced enemies like Daredevil and Spider-Man. Cobra also joined the Serpent Squad, they helped an Atlantean warlord known as Krang, but Cobra felt out of his element.

Now feeling like a new man, he decided to face his greatest fear, Mr. Hyde. He fought him face-to-face. After defeating him, he renamed himself King Cobra. He tried to get some order into this group, but it backfired and the group fell apart. King Cobra soon was arrested, and sent to the Vault. When the breakout happened he was among the escapees.

    Civil War and Thunderbolts

    The Savage Six

    No Caption Provided

    Cobra was captured by Taskmaster and Black Ant for a big trophy hunt set up by Kraven the Hunter. Kraven chose villains that were animal themed to punish them for disgracing the animal kingdom. King Cobra was one of six main animal villains that Kraven used to sell rich patrons on the hunt. Arcade, Kraven's partner, referred to them as The Savage Six.

    Once freed after Spider-Man's interfering with Kraven's plan, Vulture liked the sound of the Savage Six and pitched to his other advertised big game baddies (Rhino, Scorpion, Tarantula, and Stegron) that they should stick together. Once together, they made their way to Hollywood to shut down a production of a biographical movie produced by Mysterio that painted them in a less than ideal life. Mary Jane was on set and confronted them to no avail. Luckily, Screwball, Master Matrix, and other supervillains getting a second chance as crew members were there to rescue her.

    Sinister War

    The team gets a second chance to ruin Mysterio's movie by attacking the premiere. Unfortunately, because Mary Jane is starring in it, she was in attendance, with Spider-Man as her plus one. He leapt into action, but his attempt was short lived. The new Sinister Six showed up to recruit Mysterio and did battle with the Savage Six.

    They regroup with other supervillain teams at a graveyard where Spider-Man was hiding. Kindred let them know they were all hellbound and gave them all the same offer, the villain that kills Spider-Man will get a free pass in Hell. Eventually, Doc Ock uses a piece of Black Ant's helmet to knock everyone, including the Savage Six, out through the ear centipedes Kindred was using to control them.

    Other Cobra

    Sano Orii currently employs a super-powered mercenary named Cobra who is not Klaus Voorhees.

    The 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 is extraordinarily well trained in fighting, and even many superhumanly strong beings would have difficulty freeing themselves.

    Other Versions

    Marvel Adventures

    Cobra would be involved in a story taking place in the Marvel Adventures comics which are standalone stories and does not take place in the current Marvel Universe continuity.

    Cobra and the Serpent Society would kidnap Dr. Curt Connors when they learn the truth about his Lizard formula and forced him to experiment on innocent civilians. The Serpent Society had Dr. Connors modify his formula and had plans to contaminate the water supply in New York so everyone would transform into humanoid lizards. However their plans were thwarted by Spider Man so Cobra and the rest of the Serpent Society retreated when Connors ingested his own formula and transformed into a giant, monstrous Lizard.
