"This kind of behavior is totally unacceptable, Billy! I didn't have a Brainwave Scanner when you were five!"
"And this is how I win the world. This juncture of course is usually where the wheels come off. But not this time. Cutting the traitor Major Bludd's heart in half right in front of you, right here in this room, should have gotten the point across. It suited me once to appear weak and cowardly because it motivated you "people" to think. But today, is a new day. There will be no move to take over my command, there will be no mistakes. There will be NONE OF YOUR CRAP! NONE OF IT! Work with me, I will give you the world in less then 24 hours. Work against me, and I will gut you like a fish. Right here."

The Real American Heroes have been facing Cobra and other threats since its relaunch in 1982. The worst of those threats threaten the entire world.

A Real American Hero (Marvel) continuity
  • The original Cobra Commander himself is, underneath any silliness or ridiculous behavior, a truly vile, heinous monster who has earned his title of the Arch-Enemy of the G.I. Joes. A former car salesman who got his start with well-intentioned goals following the death of his brother, the Commander quickly moved beyond this altruistic outlook, growing in ambition and love for power as he killed thousands of people in his various maniacal plots. Returning from the grave after a seeming change of heart, the Commander brags that he has thrown away all of his humanity and redeeming qualities, illustrating this by burying his own son alive along with many of his former allies. Orchestrating a variety of atrocities that ranged from nuking cities to dropping acid rain onto others, the Commander throws away the lives of hundreds of loyal recruits to illustrate his cruelty, and his villainy culminates in the final arc of the Devil's Due series, in which the Commander murders his son, Billy, simply to prove that he can, and tries to wipe out all life on Earth so he can feel like a god. Cobra Commander goes through a variety of character twists and turns, but always is brought back to his roots: a psychopath who willingly, happily has chosen to destroy his humanity and embrace pure evil for the power and glory it brings him.

Wingfield forcibly subjects his future army—including children—to Training from Hell, and eventually tries to kill himself, his followers, and their entire families to ensure a nuclear holocaust starts. Surviving this event, a crippled Wingfield goes on to use a Computer Virus to drop satellites onto Chicago and Silicon Valley, killing thousands of men, women, and children, planning to continue to wipe out more cities. Even after death, Wingfield's abused, corrupted son Tyler tried to kill millions in his father's name, ironically unaware that Wingfield loathed the boy and had tried to kill him for being "weak".

Sei Tin eventually breaks Junko's mind and tries to force her to kill Storm Shadow while Sei Tin murders the man's pupils, which culminates in Junko regaining cognizance long enough to kill herself rather than deal with the trauma Sei Tin subjected her to. When left paralyzed following another defeat, Sei Tin gleefully takes advantage of former partner T'jbang's mercy to swap bodies with him, trapping T'jbang in his own paralyzed, mute body and mocking him daily while attempting to once more turn the Red Ninjas into his own personal army.

Born in a war-torn country, Krake raised himself to be a cold-blooded mercenary, able and willing to kill anyone in his way in his path to power and survival. Upon joining Cobra, Krake carries out a bevy of missions chosen for him, notably leading an attempted massacre of a village detrimental to Cobra's operations, until he is chosen as a candidate for Cobra Commander, at which point he assassinates a fellow candidate and orchestrates the deaths of hundreds of G.I. Joes to secure his election.

  • Rodrigo Vargas is one of the candidates to become the next Cobra Commander, and a Mad Scientist to boot. A sadistically curious lunatic who is introduced covered in blood from an experiment, Vargas begins his campaign to become the new Commander by seemingly donating countless medicine to the city of Kariba, Zimbabwe, as an act of charity; in reality, Vargas has poisoned the medicine, infecting hundreds of thousands with a monstrous plague that drives them into bloodthirsty insanity. As Kariba turns into a war zone of infected citizens tearing the military and each other apart while the government firebombs it, Vargas, suspecting his girlfriend of being a counterintelligence agent, infects her with a brain-eating parasite that destroys her free will centers, before offering her the choice of killing herself, or letting the parasite continue its course and give her an agonizing death. Even when infected with his own virus, Vargas just laughs that there is no cure, bragging that he was planning on letting the virus spiral out of Kariba and kill millions as nothing but a "test" for it, after which he could target anywhere he wanted with a horrible, plague-induced death.
  • Firefly is a Cobra operative skilled in pyrotechnics and sabotage who absolutely loves his job. Introduced blowing up a building filled with dozens of people as one of his jobs for Cobra, which is something he routinely does, Firefly later attempts to blow up an entire casino filled with hundreds on Tomax Paoli's orders, showing visible annoyance when many of the patrons flee and lower the body count.

Taking over a gang of thugs after executing their current leader, Chimera kidnaps a governor's daughter, claiming his plans to use her for ransom to his gang, before sadistically murdering her in front of her father to show his true goal isn't money, but destruction. Chimera reveals he has set two timers, one of which will release a toxin that will kill millions of people worldwide, the other which will leak stock market strategies and money laundering secrets to corrupt individuals, and will lead to economic failure within a few years. Though killed while trying to murder numerous Joes, Chimera's money laundering secrets are still leaked online. Demented and sadistic, Chimera may have been one of the earlier major villains the Joes faced, but he was easily one of the worst.
  • Cobra Vol. 2 issue #8—"Serpent's Tale Part Four: Viper's Nest": Skull Buster is the gleefully brutish recruit trainer for Cobra. Skull Buster takes potential recruits on long treks through isolated deserts in which they start out naked and vulnerable. Viciously abusing the recruits every step of their training while ruthlessly murdering any who show weakness, Skull Buster forces them to slaughter anyone they come across to steal their supplies, from Taliban soldiers to entire villages of innocents, including children. Revealed to repeat this kind of training every week on new recruits simply because he loves it, promising that by the time he's done each group will only have "one survivor", Skull Buster seems pleased that his latest group has two survivors, only for one of them to kill himself in sheer revulsion of Skull Buster's evil. Skull Buster simply chuckles "Heh. One."

The Commander forces Shockwave to exhaust all of his energy in bombing his foes, uncaring that he's killing most of his slave labor while remarking "that's what they're for", after which Cobra Commander proclaims his intent to overrun the world with his tyrannical rule and institute himself as a god, deciding on a whim who lives and dies under his megalomaniacal boot.

Scheming to invade Earth, Shockwave successfully turns the planet into a warzone, killing billions of humans and keeping countless more as slave labor who he routinely executes by the dozen when they fall behind in their workloads. When the past is altered and Earth is saved from this invasion, Shockwave instead attempts to bring about a time fracture upon Earth, bathing the planet in nuclear fire for decades and wiping out all life on the planet so he can then gut the planet of its resources, and planning to keep human survivors as experiments for him to vivisect.

Having devoured countless planets over millennia, Unicron struck a deal with Cobra-La on Earth that he would spare the planet for a few centuries until there were billions of humans populating it, at which point Unicron would return and consume them all, leaving the barren husk for Cobra-La to rule. When the G.I. Joes and Transformers try to stop Unicron as he causes natural disasters worldwide and kills countless people, Unicron sics his "antibodies" on them, gleefully boasting his plans to slowly eat them all alive in the same fell swoop that he consumes Earth.

Capturing and twisting several Transformers into his monstrous slaves, Golobulus uses them to slaughter anyone who tries to uncover his plans, and even takes humans captive to be kept as tortured pets.

With this new group, Cobra Commander's evil only increases, as he tries to kick-start wars, enslave London, and finally infect all of humanity with a plague, the cure for which he will only give to those who will bow down to him. Cobra Commander is also a horrific boss to his minions, subjecting them to training that kills dozens of them at a time, executing them for the pettiest of slights, and feeding them to ravenous beasts regularly for his own amusement. Be it as Ironblood or Cobra Commander, this power-hungry madman would let no man, woman, or child come between him and his goals, and he kills thousands of them to illustrate this point.
  • Extreme, written by Mike W. Barr:
    • Iron Klaw is the main villain the military team the G.I. Joes confront in this comic miniseries, and handily the worst.

After murdering the Duchess when she slowly shows disgust for his homicidal plans for world domination, Iron Klaw murders a man, taking out many of his soldiers in the same instance, to steal his political position, and proceeds to steal the powerful crop hormone known as Ferti-gel, poisons it, then plans to spread it across numerous countries to plunge them into famine and drought in order to blackmail the world with his massive supply of food.

Using his pyrotechnic skills, Inferno bombed more than half a dozen military bases, killing dozens of innocent American soldiers, and follows it up by blowing up an American intelligence agency, killing more than thirty people. After bombing the recently-created G.I.

  • Reloaded:
    • Cobra Commander is a self-serving sociopath masquerading as a well-intentioned revolutionary. As the leader of the terrorist group Cobra, the Commander is a power-hungry madman obsessed with bringing America to its knees, and kicks the story off by blowing up the Golden Gate Bridge and the many civilians on it. The Commander's ultimate plan is to drop the Omega Black virus onto a highly-populated city, which will horrifically melt millions of innocent people, at which point he will blackmail other cities to cow to his whims. When his plans are thwarted, the Commander attempts to simply launch as many nukes as possible as he makes his retreat. Despite his supposedly benevolent attitude toward his minions, the Commander shows his true colors as he ruthlessly executes anyone who fails him, even animals, and goes on a murder spree of his own soldiers for the slightest of reasons, showing himself to be just a petty, raging bully given power.
    • Firefly is a mercenary-turned-Cobra agent who takes joy in classical music and blowing things up. After bombing the Golden Gate bridge in Cobra's name, killing dozens, Firefly derails a train and executes the surviving passengers with a gun to steal supplies which he uses to take over an oil rig whose staff he massacres. Firefly murders anyone who tries to approach the rig, and later mocks a Joe over the fact that Firefly killed the man's girlfriend in a previous job.
  • Future Noir, written by Andy Schmidt: In this non-canon, alternate universe, the sociopathic Dr. Mindbender is portrayed as far worse than his mainstream counterpart. Mindbender performs horrifying experiments on numerous innocents, including children, who are drawn into the cult of Cobra. These experiments leave them as hideous monsters in constant agony that he uses to kill anyone who defies Cobra. With raving fanaticism for his leader, Serpentor, Mindbender plans to spread a toxin countrywide that will turn all it infects into monstrous and mangled beasts in order to leave only the "pureness" of the Cobra cult to exist in the world. Commiting his crimes For Science! and misanthropy, Mindbender stood out as a wicked monster who more than made up for the relatively low quantity his crimes with the sheer monstrosity of said crimes.
  • 2019 series: Anastasia DeCobray, better known as The Baroness, is a cheerfully destructive Cobra officer with zero allegiance to any ideology except violence itself. Revealed to be the one who suggested the utter decimation of Indianapolis and its population to quell rebellion, the Baroness continues to suggest similarly brutal tactics in the present, threatening to destroy any and every city across America that G.I. Joe crops up in with no care for the body count. Commissioning Dr. Mindbender to perform inhumane experiments on reviving dead Cobra troops, the Baroness casually sentences a Cobra guard to be taken apart by Mindbender and shows her further distaste for her own subordinates when she snaps a Cobra operative's neck to use him as a Human Shield. The Baroness cements herself as the worst the otherwise well-intentioned Cobra has to offer in this continuity, basking in her belief that destroying hope is "beautiful".

Refusing to share the planet with anyone else and finding humans to be disgusting apes, Golobulus created the terrorist organization Cobra and installed Cobra Commander as his puppet, using the group to commit a variety of atrocities against the human race in an attempt to exterminate or subjugate them. Tired of Commander's constant inept failures, Golobulus painfully transforms the man into a snake, then reveals his plans to repeat a similar process on the entirety of humankind, reducing billions to submissive beasts for Golobulus to lord over. When the G.I. Joes attempt to thwart his plans, Golobulus sadistically brutalizes and tries to murder them all, bragging his intent to bathe in their blood before moving on to conquer all humans.
    • DiC run:

Intending to spread Spark on a global scale and bask in the ensuing fortunes despite the suffering it will cause, the Headman takes two of his addicted victims as hostages when G.I. Joe and Cobra team up to take him down, and attempts to douse several members of each group with concentrated Spark to horribly kill them all with the toxic chemical. Even after getting hit with the concentrated Spark, the Headman hits the self-destruct sequence for his base, trying to ensure the Joes and Cobra die as well.
  • Extreme: Iron Klaw is the maniacal leader of SKAR (Soldiers of Khaos, Anarchy and Ruin), using his public guise of Count Von Rani to cover up his heinous acts.

In one of his most horrific crimes, Iron Klaw subjected dozens of captured men to experiments that left them mutilated monstrosities that he abandoned to die, and when the sole "success", Wreckage, lost his memory, Iron Klaw manipulated him into believing America was behind his trauma, and uses him as a weapon that he discards as soon as he runs out of usefulness. Iron Klaw's grandest scheme comes when he invades a meeting of dozens of world leaders and infects them all with a deadly plague, using them as hostages to enable his takeover of America, and, when Iron Klaw's attempts to gain control of America's nuclear weapons to use in a conquest of Earth fails, he orders the world leaders be burned alive and their screams broadcasted for all his enemies to hear.

Joes.

To combat the Joes, the Commander threatens their entire families with death, kidnaps one of their number to experiment on, and frames them for heinous crimes committed by Cobra itself. After his bevy of plans to Take Over the World through more subtle methods are consistently thwarted by the Joes, the Commander forgoes all attempts at obscurity and tries to lead a full-on invasion of various countries using the M.A.S.S. device.

A psychopathic Mad Scientist who develops the Bio-Viper army for Cobra, Mindbender experiments on innocents to assist in his projects, and works with Baroness in ordering the deranged Firefly to destroy a small town and its inhabitants. Torturing the twin psychics Tomax and Xamot in an attempt to use their powers for Mind Rape, Mindbender later tries to destroy Brooklyn, New York just to distract the Joes from his activities, and interrogates and threatens a young child for information in the same episode. As Cobra develops the M.A.S.S. device, Mindbender cheerfully tests it on Cobra's own soldiers, uncaring of any deaths it causes, before trying to send Snake Eyes through it and kill him while making his best friend Scarlett watch.

Using the nanomite technology to mind control a variety of soldiers—even his own sister Ana, the future Baroness—"the Doctor" planned to assist McCullen in using the nanomites to wipe out major cities, before using Zartan to replace the President of the United States for ultimate power. After the nanomite plan fails, "the Doctor" betrays McCullen, uses Ana as a hostage, tries to blow up his entire lair and everyone inside and christens himself Cobra Commander. Later escaping prison, the Commander uses Zeus to destroy London, promising to continue wiping out entire cities until the world cows to Cobra.

Joes and kickstarts a war in a foreign country to enable Cobra Commander's escape.

  • The Rise of Cobra (primarily): James "Destro" McCullen is the head of Military Armaments Research Syndicate (M.A.R.S.) Industries, using the company to mask his growing schemes for power. Able and willing to sell weapons to terrorists worldwide and eager to test out said weapons on anyone in close proximity, McCullen works with the Doctor to create the powerful machines called Nanites, using them to turn hundreds of men into enslaved soldiers fully aware of their surroundings but unable to control their own actions.

McCullen also arranges for the deaths of his own troops should they be captured, has the President's security detail killed, and keeps the Baroness as his enslaved puppet to seduce, even ordering the death of her public husband out of mere jealousy.

Joes, killing dozens upon dozens of unsuspecting soldiers. Later mocking Roadblock over this slaughter of his friends, Firefly is tasked by Cobra Commander in securing the Project Zeus control case so the Joes can't stop the weapon, something Firefly quickly accomplishes, nearly murdering fellow Cobra agent Zartan in the process just because he dislikes the man.
