He ACTUALLYkills this baby. After his demands have been met!
You think I do this*
kill people
for money?! I've been gettin' paid for high-end jobs since... forever. Have you ever seen me spend any of it? Hell, I wouldn't be surprised if I have more money than you, at this point. No, Norman... I stopped doing this for money a long time ago. I do it because it's fun.
When The Shadow King isn't hatching some diabolical plot that the X-Men have to stop, he likes to use his telepathic power (nearly equal to Xavier's) to alter people's priorities, amplifying their dark impulses and suppressing their conscience, so they do awful, ghastly things of their own free will, at least, in a sense. Murder, adultery, anything, and then he sometimes reverses the effects and leaves him or her remembering doing those things, remembering enjoying them, and wondering why they did it.
A good portion of the Marauders have been this. Riptide is an Ax Crazy sadist who loves nothing more than indiscriminately slaughtering everything in sight, Scalphunter is a ruthless sociopath who will do anything if the pay is good, Blockbuster is a bloodthirsty brute who relishes torture, Scrambler is a narcissistic psychopath with a love for chaos, Malice is a sadistic incorporeal spirit who is second only to Mystique in Manipulative Bitchery, and Sabretooth is, well...what hasn't Sabretooth done? Makes sense when you consider that Sinister, who commissioned the team, is one of the most despicable individuals in the MU.
Let's talk about Mr. Sinister, shall we? Sinister was the one who commissioned the Marauders to slaughter a bunch of innocent Morlocks. He then callously played upon the feelings of Cyclops, creating Madelyne Pryor as a clone so she and Cyclops could produce a child for his experimentation. He's spent decades performing horrible experiments on mutants and was a key figure in Nazi human experimentation. Perhaps Sinister's most vile act is promising to free those enslaved in the Weapon X concentration camp. In reality, he merely took them as his own test subjects.
Cassandra Nova, who kicks off her first appearance by murdering sixteen million mutants, entirely for the purpose of inflicting pain on Professor X. And then there's her Mind Rape of Kitty Pryde...
And despite being an Ass Pull by Chuck Austen to try explaining the huge OOC Ball that she was given, Nova forcing Polaris to witness the already mentioned massacre wasn't the kindest action either.
Ultimate Magneto. In contrast to his noble, at times even heroic mainstream counterpart, he's a coldly calculating genocidal sociopath who has twice attempted to wipe mankind from the face of the earth. He also verbally and physically abused his children (ordering Wolverine to kill his son at one point, and later kneecapping him). Although, to give him his due, the Ultimate Universe is even harsher to mutants than the mainstream one. Ultimate Deadpool and Ultimate Mojo are also completely monstrous: Deadpool gave a speech on TV about how the X-Men (who he repeatedly described as "babies") didn't choose to be mutants and were just born that way, before dismissing them and all mutants as animals who deserved to die horribly, while Mojo's plan was to force Professor X to watch them being hunted down and slaughtered by Deadpool and the Reavers for a reality TV show before lobotomizing him live on air! (Fortunately, they hadn't planned for Spider Man's intervention and Xavier took an unspecified revenge on Mojo instead). The Ultimate Universe is generally a lot Darker and Edgier than the classic Marvel universe and Complete Monsters are almost commonplace.
Ultimate John Wraith is a mutant-hating bastard (admittedly, he isn't alone there) who tortured Wolverine for years and wiped his memory, broke Rogue's arms constantly from boredom, and turned young Nightcrawler into an assassin, an act that left him psychologically traumatized. He was kicked in the balls by karma when Ultimate Fury shot him in the head, though he came back as Vindicator for Alpha Flight. Quite WHY this happened is beyond most readers and several are choosing to forget it as severe Character Derailment.
Dr. Zander Rice, one of the lead scientists of Weapon X's X-23 project. He has X-23 kept in a padded room except during training sessions or assassination missions, almost kills her with radiation poisoning to trigger her healing factor at the age of seven, and surgically removes her natural claws one at a time, coats them with adamantium, then reimplants them (all of this without anesthesia) at the same age. He develops a pheromone "trigger" that activates her berserker rage and uses it to get X-23 to kill her martial arts instructor, and leaves her behind on a mission to be killed after he murders the other members of the team so he can claim they were taking fire and had to retreat. After X-23 shows back up alive, Rice then manipulates the head of the X-23 project, who had raised Rice after his father's death, into granting Rice control of the project, at which point Rice then sends X-23 to kill the man, his wife, and son - even though Rice knows the boy is his son, from an affair between Rice and the wife before her marriage (X-23 leaves the child alive). Upon taking over the project, he begins the development of embryos X-24 through X-50, which he intends to sell to the highest bidders, and then taints the one remaining person X-23 cares about, the project scientist who was her surrogate mother, with the trigger pheromone, which causes X-23 to fatally injure the woman - just as she was about to take X-23 and disappear after destroying the project complex. Rice's reasoning for all of this? His father, who worked on the original (Wolverine) Weapon X project was killed by Wolverine when he escaped, and Rice held X-23, who is Logan's genetic double, responsible for Wolverine's killing of his father. Somehow, X-23 kicking the shit out of him and his dying doesn't quite balance the scales...
Fabian Cortez deserves a spot on this list. He was part of the defunct Upstarts, a group of rich, bored dilettante mutants that hunted and killed other mutants for points and bragging rights (the competition was set up by Selene to test possible recruits for the Hellfire Club). In his first outing, he puts together the Acolytes and seeks out Magneto in order to sway him back towards taking an antagonistic stance against humanity again. When Magneto is wounded, Cortez uses his own powers to seemingly heal him and boost his power at the same time whilst making Mags dependent on the “treatments” like a drug (and possibly making Mags more emotionally unstable, which would account for much of his behavior during “Fatal Attractions”). His machinations lead to the U.S. and Russia destroying Asteroid M with a plasma cannon, and the deaths of his entire first group of Acolytes (what makes that worse is that one of them was his own damn sister, and yet he never acknowledges that, nor does he show any signs of remorse or grief), whilst he flees with a triumphant smile on his face. When Magneto turns out not to be dead and he loses his top spot in the Upstarts competition, his response is to go to Genosha and inspire the mutants there to rise up against their oppressive human government, causing a bloody civil war. At the same time, he kidnaps Magneto’s infant granddaughter (and replaces her with a shapeshifting mutant suicide bomber in an attempt to kill as many of the Avengers as possible) so he can use her as a human shield against her parents and grandfather, the X-Men, the Avengers, and Exodus. When Magneto is given rule of Genosha, he grants Cortez a place on his cabinet in exchange for regular rejuvenating treatments (Magneto’s powers are in decline at this time). As soon as Mags learns of hidden technology in Genosha that can restore his power levels again, Cortez predictably betrays him again by amping up ex-Acolytes to send against him. This fails, and as soon as Magneto restores his full powers, he grants the weasel a messy, but long overdue death. Not only was Cortez an extreme mutant supremacist, a terrorist, a coward, a user, and a backstabber, but he also committed his most despicable crimes to score points in a competition.
Victor Creed, aka Sabretooth, the Evil Counterpart and formerArch-Enemy of Wolverine. He may be the only person in the 616 Marvel Universe who enjoys killing people more than Bullseye. In one issue of Deadpool, he killed a bunch of people for fun. Bad enough. Then it was revealed that he had kept a little girl in a closet that he was saving for later. Even the possibility that his homicidal nature might be part of his mutation doesn't excuse his actions. It would not be an exaggeration to say that Sabretooth embodies everything ordinary humans hate and fear about mutants. Thankfully, he receives a very Karmic Death. First, he gets Mind-Raped by Romulus and made into his bitch. It's so bad that Sabretooth ends up begging Wolverine to kill him. Wolverine gladly does so, beheading him with a magical katana that negates his Healing Factor, killing him for good.
Omega Red. The man was a Soviet soldier stationed at a small town who started murdering from sheer boredom. His fellow soldiers shot him in the back of the head when they caught him. The Russian government learned he survived and recommended him for the Soviet supersoldier project, which he apparently only survived due to his evil and mean nature. To survive carbonadium poisoning, he drains the life forces of those around him, even when a cure is available. It was at one point implied that he was a pedophile, though thankfully, writers seem to have forgotten it (Red was, by this point, developing into too dark a figure). He later turned on and killed several of his employers working for the Hand for the reason that they irritated him. In his presently final issue, he ends up in a regular Russian prison and taunts a prisoner dying of HIV/Aids by calling him worthless. He later casually kills Wildchild by impaling him through the chest and dumping him in molten lava before being stabbed by the same blade that killed Sabretooth.
The X-Men honestly have a ton of these to contrast with a Magnificent BastardAnti-Villain like Magneto. There's the Marauders and Sinister mentioned above, but some of the others include Sinister MinisterWilliam Stryker, the founder of the Purifiers. The Purifiers are an organization of religious fanatics who believe Mutants are an affront to God. Their first appearance opens with them gunning down a nine year old girl and eleven year old boy. Stryker's crusade began when he killed his baby mutant son...and then broke his wife's neck for giving birth to a 'monster'. He tries to brainwash Professor Xavier so he'll kill every mutant on the planet and murders his second-in-command when it becomes clear she has the mutant gene. His own guards even turn on him when he tries to kill Kitty Pryde on live TV.
Donald Pierce, the cyborg leader of the Reavers. Pierce was a member of the Hellfire Club for a time, but is really a psychotic, raving bigot who's also a serial killer of mutants. His hatred motivated him to turn people into Cyborgs to kill more mutants. What makes Pierce the worst, though? Pierce knows if he goes after guys like Wolverine, Cyclops, Magneto, or Havok, he's going to get his ass kicked...so he targets baby and child mutants who can't fight back like they can. Pierce is a vile, spiteful, cowardly bully so filled with hate, his last words before Cyclops kills him is to say he's just sorry he won't be around to see the Mutant Race destroyed.
Pierce actually did go after Wolverine the one time, with the help of Lady Deathstrike and the Reavers; they ambushed Wolverine, beat him down, then crucified him in the Australian desert and tortured him. If not for Jubilee, Logan would surely have died; as it was, the ordeal severely taxed his healing factor and screwed up his mental state for months of Comic Book Time (but years of our time). Pierce can actually claim to be among those who have come closest to killing Wolverine, and in such a horrific way that the son of a bitch belongs on this list.
Vulcan, the savage, insane third Summers brother. Vulcan starts with an almost sympathetic motivation, wanting vengeance on the mad Shi'ar Emperor D'ken who killed his mother (and D'ken can easily fit this trope), but soon enough, it becomes clear Vulcan is a savage beast. He kills anyone in his way, innocent or no. When he kills D'ken and assumes control of the Shi'ar throne, his first act is to brutally murder his own father. He takes vicious delight in torturing his elder brother Havok and seeks to break him mentally at every opportunity. He then expands the Shi'ar into a brutal dictatorship who conquer all they can, losing himself completely to madness.
Reverend. Craig. The father of The Woobie Rahne Sinclair. He spent thirteen years being a horrific, abusive monster on par or worse with Brian Banner, to the point Rahne thought she was a horrible person who deserved to die - and that's BEFORE she found out she was a mutant. When he found out, he shot her and tried to have her burned alive. He later helped the Purifiers brainwash Rahne into a killing machine, which leads to her giving the bastard a horrible Karmic Death by way of her claws and fangs, due to the brainwashing she got activating when she sees him as an angel due to Angel's wings.
Two queens of the Hellfire Club. The White Queen Adrienne Frost, sister of the more famous Emma. Adrienne is ruthless, manipulative, and most well known for setting a bomb in a school to kill the students. She later admitted she would only keep doing more and kill every student she could before Emma murdered her to save her students. And the Black Queen, Selene, the most ancient mutant alive who survives by sucking the life force from people. And recently, she showed her worst by reviving the dead of Genosha - to enslave their souls to her. She also killed Eli Bard, her loyal aide who showed her that he truly loved her.
Believe it or not, there was a New Mutants miniseries in which Selene was an ally. This premise was so silly they had to bring in the Red Skull (see below) to be the villain in order to make Selene having the moral high ground make any sense at all. Perhaps her cruelest action? Manipulating Wither, a good kid with bad powers who had recently lost everything, into becoming an Omnicidal Maniac by simply being the only one to provide him with any companionship. It's heavily implied the she'd have discarded him (as she did Bard) as soon as her plans were successful. Which they are, though neither of them live long enough for her to do it.
God, we have some more. Looks like the writers need to learn a bit more subtlety. APOCALYPSE, people. The man is one of the oldest mutants in the universe and lives by a very Darwinist principle, which he is not above judging himself by. He planned to kill the world with a super virus - even Sinister was a bit disgusted (albeit due to issues of efficiency and NOT ethics). He's an out-and-out one, albeit when he was recently reincarnated as a kid, he was genuinely and potentially redeemable.
The man had an alternative reality crossover (Age of Apocalypse) in which most of the world, except for parts of North America, Western Europe, and North Africa, became an irradiated wasteland. He ruled North America by callously killing thousands, and to make things worse, his son from that reality, Holocaust, was implied to be worse. Holocaust was so dark, they even changed his name to Dark Nemesis, after he struck uneasy chords with those all too familiar with World War II (and because it's impossible to sell a toy or trading card with the name "Holocaust" on it.)
The Gauntlet, a group of mutant businesspeople in X-Man #63-66. Nate initially defends them from a monster from an Alternate Universe, but ultimately turns on them after learning why the monster's after them: They're a group of Corrupt Corporate Executives who, while using their powers to explore The Multiverse, happened upon a Death World version of Earth whose natives — the monster's species — managed to survive the harsh, rapidly changing environment through their capacity for rapid adaptive mutations. Seeing the potential profit, the Gauntlet proceeded to steal a number of the natives' children, bring them back to Earth to harvest their highly adaptable organs, and create a barrier around the Death World to try to prevent the parents from following them. In the end, as Nate informs the Gauntlet that he knows what they did and prepares to execute them, he sees in their minds that they're not guilty about it, just afraid of being punished. To them, what they did was just a sensible business decision.
The aforementioned Romulus from Wolverine probably counts. The man may have been a Villain Sue and had some elements of Magnificent Bastard or Manipulative Bastard, but still, he counts on some level. He manipulated several of Wolverine's ancestors in an attempt to get the perfect killing machine, eventually leading him to Wolverine himself. He mind-rapes Sabretooth into raping and seemingly killing Silver Fox (Sabretooth is also a complete monster, true, but if you can make an asshole like him beg for death to escape you, you must be fucked up beyond belief). He then recruits an assassin to kill Wolverine's pregnant wife on the small chance that the child will inherit Wolverine's factor and survive. Because he was never raised by his proper parents, Daken had a seriously dark and depressing childhood that may never have happened if not for him. He then moves Omega Red into a regular Russian prison, where he ends up killing all the guards and seriously injures, if not outright kills, most of the prison.
The lackey of Romulus, Cyber, is definitely one, having been found guilty for twenty-two murders BEFORE he meets Wolverine. When Wolverine was still relatively young, he willingly murdered Wolverine's then-love interest Janet before gouging his eye out. This leaves him with a deep, psychological fear of him. He finds domestic abuse fun, protesting against it only for the reason of impracticality. He's also got no qualms about brutally beating some recruits he trains simply because he hates them, and not for the purpose of toughening them up. At one point, his employer notes he's in it for the hurting people and not the money, a fact that bites his employer in the ass when he tries paying him triple. It was implied he took part in the West Port murders in 1828. He also uses child soldiers so Wolverine won't kill all his mooks, and he does a Grand Theft Me on a young, mentally-handicapped mutant. Thankfully, he ends up dying twice for double the karma.
The CEO of Blackguard qualifies, as do most of his Wolverine-style special ops team (except the leader of said team, who will not kill a child or fight in front of them for fear of traumatizing them). He casually states that for the cost of a very rare wine bottle, he could feed most of Africa for a year, stating that the bottle of wine is a much better spend of money. He willingly lends the Wolverine style ops team to Roxxon as protection for the mining facilities, but the lengths they go to are extreme and cruel - they end up killing a village of innocents before they find the sole survivor, stuff a grenade in his mouth, then kill a resistance movement. And then he ends up trying to kill a journalist who was going to reveal his activities, and thankfully succeeded in doing so, as Maverick ended up killing her assassin. And to try and prevent further discovery, he ends up killing off an executive who was completely uninvolved. Because of a few minor people resisting, they killed A VILLAGE. Most of the team is made up of disgraced military operatives, including those discharged for rape, friendly fire, and unauthorised killing. Wolverine comments that the youngest of the group he finds either had all his humanity removed from him by Blackguard or had none to begin with.
Potentially viler than all of the above is incredibly minor villain Johnston Coffin, featured in four obscure issues of Generation X. He's wanted by SHIELD for crimes against humanity, but instead somehow finds himself employed by the US Government. With the government's blessing, he builds a Hellhole Prison where he "fixes" disobedient teenagers, many of which had only said or thought something disobedient. What really puts him over the line, though, are his "Special Children" - kids from his first Hellhole Prison in the '70s, whom he's wired up to huge cyborg bodies and uses as security. They've been that way so long, it's implied in perpetual agony, that their bodies have actually begun to rot. He also has half a human mounted on his wall, is implied to be a rapist, and carries around the skull of a child he shot in the head everywhere he goes.
Just to point out: the Skull isn't a Nazi anymore. It's not that he's got anything against Nazis either. He just thinks he's superior to them. Yes, he's even more arrogant than a group of people so narcissistic they called themselves the "Master Race". And the scary thing is he's only become even MORE evil since renouncing the Nazi cause, not less. The guy didn't just go past the Moral Event Horizon — he IS the Moral Event Horizon. Even sadistic mind rapist Dr. Faustus is disgusted by him. In a cross-over with DC, even the frickin' Joker ended up being disgusted by him.
There's also the way he treated Mother Night, the only woman who actually loved him. He treated her like crap and usually just thought of her as another henchman. In a lot of ways, it's like the Joker and Harley Quinn relationship, but Skull is far more abusive. Red Skull once even started flirting with Viper right in front of her just to make her suffer (he slept with Viper, too). What Mother Night sees in him is a mystery, though she also considers Crossbones to be a close friend, so she isn't a good judge of character. Mother Night isn't a saint herself.
However, another minion of the Red Skull, Arnim Zola, seems like a complete monster in his own right. He was a Swiss scientist who chose to work for the Nazis to get funds and "test subjects" for his genetics research. Now, that's pretty bad, but It Got Worse. He put his mind into a genetically altered body that allowed him to survive into modern times. So now he does things like make Hitler clones and kidnap orphans in order to turn said orphans into genetically altered monsters. Also, he revived the Red Skull after he died, by transferring his mind into the body of a Captain America clone, ensuring the Skull's evil would continue.
It seems to run in the family, as Red Skull's daughter Sin is one as well. She's just as vicious as her father, although significantly more Ax Crazy. Although she does wear her father's Nazi attire (and sports matching facial scars), she seems significantly less interested in the Nazi philosophy and more interested in just killing as many people as possible For the Evulz.
Crossbones is another one; understandable, considering that he had to meet Sin's standards to be her boyfriend...which didn't stop him from torturing her to remove the brainwashing she was subjected to. He was recently put in the Thunderbolts. Not because anybody has delusions he deserves a chance to redeem himself, quite the opposite - he was added to the team because he is so irredeemable and disgusting that other members are more willing to cooperate, as trying something would put them on the same side as him. It got to the point where he killed a police officer and was booted off the team.
Crossbones actually managed to start up a Real Life racism and sexism controversy when an issue of Spider-Man depicted him, a Neo-Nazi rapist, apparently killing the superheroine Sabra, a Jewish single mother, by shooting her In the Backwhile nonchalantly munching on a sandwich. The writer actually had to get on Twitter and confirm he'd just grazed her, things got so bad. Still an excellent window into the kind of guy he is, nevertheless.
The Red Skull in the Ultimate Universe is actually WORSE, as demonstrated in the image above. He's a killing machine, although that doesn't sum up the sick delight he takes in what he does. He's mentioned as having worked with numerous historical monsters including infamous mass-murderer and cannibal Idi Amin. He makes a hobby out of training terrorists and, oh yes, he's the guy who killed Kennedy. Just to send a message. His evil is highlighted in his backstory, where Nick Fury relates how he gave a man's wife a Sadistic Choice: kill her husband with a pair of scissors or he'd kill her baby. She did it. The Red Skull then chucked the baby out a window and let his three thugs gang-rape the woman. Oh, and he also stole all of the food and drinks in their house too. Karma does kick him in the crotch when he gets impaled by A JETPLANE BY HIS OWN FATHER and then shot by the same woman whose baby he murdered, but it's a far easier death than any of his victims. And he's Captain America's SON!!!!
He also forces every member of A.I.M. to EAT each other when he gets his hands on the Cosmic Cube. He got his start by killing two hundred people at the age of seventeen and then cut off his face.
Yet Even Evil Has Standards as there was one individual that was too evil even for him: his one time partner and lover Viper, a.k.a. Madame Hydra. She is the former head of HYDRA, a Southeast Asian dictator, and an all-around mass-murdering terrorist mastermind. She is so evil that even other supervillainsteam up with heroes to take her down. Skull was the only one she would even work for, but after he saw all the damage she did with his resources, it was discovered even the Red Skull had his limits and he turned on her. Though it was less a case of morals than it was of efficiency: Viper was wasting the Red Skull's resources to cause pointless destruction. The Red Skull might enjoy petty sadism, but he's not about to bankroll someone else's petty sadism.
There are several Marvel Universe characters probably intended to be this:
Bullseye, a Psycho for Hire enemy of Daredevil who not only kills people for pay, but also just for kicks; It's been revealed he rarely spends the money he makes from killing.
Psyko, an enemy of Sleepwalker who cut out the hearts of at least fourteen women as a Serial Killerbefore becoming fused with an otherworldly demon and gained the power to viciously Mind Rape his victims and make them Brainwashed and Crazy.
Purple Man, an old Daredevil villain with the power of Mind Control who was revamped by Brian Michael Bendis into a rapist/serial killer who would force people in restaurants to stop breathing because the noise in said restaurant was bothering him. The animated series version of the Purple Man is just as bad; he uses his Villain with Good Publicity status to take in several mutant children to hypnotize them into assaulting the governor's house to force him out of office and hand over control of the local waterfront project to him. Then, when he gets found out, he tries to use those kids to kill Cyclops (who was snooping around at the time), then burns down the orphanage they came from in an attempt to kill Cyke. And he does this all without showing any remorse or care for anyone but his own greed. And what he did to Jessica Jones and Swordsman...
Scarecrow (not to be confused with Batman's enemy), the villain who fights Ghost Rider on a regular basis, also fits. He is a psychopathic child killer who once murdered a mother and her baby with a pitchfork. But that's not even the worst thing he has ever done. Later on, he tried to make a building out of people by sticking them all together (some were dead and some were alive). When Ghost Rider saw this, he broke every bone in Scarecrow's body and the audience rejoiced.
Bruce Banner's father, Brian, was a particularly loathsome example cut from a different cloth than most of the characters on this list. An abusive alcoholic who was insanely jealous of the attention his wife, Rebecca, gave to his newborn son, Brian convinced himself young Bruce's amazing intelligence was due to his own exposure to radiation as a nuclear researcher, which resulted in Bruce being born a "monster". After years of physical and emotional abuse, Rebecca decided to leave Brian and take Bruce with her, and in retaliation, Brian killed her, intimidating Bruce into not revealing the truth to the courts, but ended up revealing himself in a drunken stupor, resulting in him being institutionalized for years. After being released, he was placed in the now grown-up Bruce's care, but it quickly became apparent he hadn't really changed and still regarded his son as a freak and attempted to murder him only for Bruce to kill him in self-defense (though it is suggested that Bruce actually enjoyed doing it on some level). He was so unpleasant that the cops didn't even bother to run an investigation on his death when they found the body. The worst thing about Brian Banner is that despite him being a fictional comicbook character, there is absolutely nothing about his story that is fantastical or supernatural; although the abuse he put Bruce through laid the psychological groundwork for the Hulk's birth, Brian himself wasn't a masked supervillain, a Mad Scientist, or even a victim of Demonic Possession. He was simply an evil bastard who did horrible things and is a person who can quite possibly exist in everyday life.
It Got Worse in a What If? issue, where Bruce himself ended up apparently admiring the guy and taking on all of his worst traits. A thoroughly disturbing comic book commenced, where poor Betty was beaten, hospitalized, and, when she finally drew up enough nerve to fight back, Bruce abused his connections to have her committed. Somehow, the small blurb at the end about seeking help for real life cases of domestic abuse didn't seem enough to offset the Unfortunate Implications...
During the Chaos War, he came back...as some sort of Devil Hulk and Guilt Hulk mix. To clarify, those are the two most monstrous Hulk personas in Bruce's mind, the latter being an incarnation of his guilt and the former being every single worst bit of his personality turned Up to Eleven. Think about it.
Sadly, Bruce's father may not be the only monster in the family. His estranged son Hiro-Kala, an insanely powerful brat with a god complex, verges on Complete Monster territory, if he isn't there already.
Nicky Cavella is no ordinary mafioso, but murdered his family (including his aunt, although she was molesting him), chopped up and fed a Triad boss' son to him, killed a cop he'd taken hostage, and started the "Up Is Down, Black Is White" arc by digging up and urinating on the skeletons of the Punisher's wife and children, then deliberately sent the video to the nightly news so that Castle would see it, with Cavella himself clearly identified as the culprit. While it succeeded as intended in throwing off the Punisher's self-preservation instinct, former associate Rawlins pointed out that there was no way that mere gangsters could actually take advantage of this. He met his end following a botched attempt to finish the job himself after losing Teresa (sister of the henchman Pittsy from the first arc), Rawlins, and his entire gang to the Punisher — who'd killed so many of Nicky's men that he couldn't threaten those who wanted out — and O'Brien.
Rawlins dumped a crewman (killed) and his wife O'Brien overboard to be raped by the Taliban so that his helicopter would be able to stay airborne with him and the drug shipment, activates a terrorist group to hijack an airliner and fly it at the Kremlin as a diversion for another operation, and when he murders Zakharov's right-hand man (who seemed, along with Zakharov, to recognize the sniveling Jerkass underneath the Smug Snake exterior), he taunts the dying bodyguard by vowing to rape his son to death. A similar kill attempt doesn't work against the Punisher soon after O'Brien's death, and Rawlins meets a well-deserved end in a Kabul airport restroom.
There's no way Zakharov doesn't qualify for this trope. When he was having civilians massacred during his stint as a Soviet general in Afghanistan, a woman begged him to spare her baby. His response? He took it and threw it off a cliff. Any claims of his moral superiority to the mercenary scumbag Rawlins dies a horrible death after learning this.
Which is a bit of a twist since the "Mother Russia" arc (the first story he appears in) sets him up as a Magnificent Bastard. Fridge Brilliance sets in when his quote "He is no more likely to kill millions than me" (referring to the Punisher) takes a whole new meaning when we learn of his Moral Event Horizon.
There needs to be a nod to the Bulats, father and son Tiberiu and Cristu and their associate Vera. Tiberiu and Cristu were part of an Eastern European militia responsible for ethnic cleansing, slaughtering entire villages until Cristu got the idea to take young women captive. They forced them into sexual slavery and went to the United States to export the business. Tiberiu is a trigger-happy madman who'll kill anyone at the slightest provocation while Cristu and Vera are calculating business types who routinely have the girls raped. What Frank does to these three? Some of the most brutal acts he's ever committed. And it's never been more satisfying.
MAX versions of Kingpin and Bullseye. Kingpin cemented his status by coldly gunning down the enemy mobsters that held his son hostage at knifepoint — the monstrosity coming from his hardly feeling anything when the kid was killed as a result. Bullseye is so disturbingly insane that even his mainstream counterpart, who kills people for kicks, probably would have been squicked by things MAX Bullseye did, like repeatedly murdering whole families to, supposedly, better understand the trauma that created the Punisher.
Bullseye is the kind of sick bastard who gets off on seeing a vigilante like Castle butchering his henchmen. To Bullseye, watching someone kill scores of men is like listening to a symphony.
There's also Barracuda. As quirky and entertaining as Barracuda is, he really has no redeeming features whatsoever. He'll use, betray, or kill without any compunction and engaged in cannibalism to show how manly he was as a Green Beret. What sends him over the edge is the 'Long, Cold Dark' arc where 'Cuda abducts Castle's infant daughter so he can torture and kill her, just so he has a way to torture Frank for shooting him and leaving him for dead.
He definitely reached this point by the time of his post-Clone Saga resurrection, though. Spent years torturing Peter, designed a DNA bomb to kill everyone on Earth, and, oh yes, he recently ordered a commercial airliner full of innocent people shot down...just so he could get at ONE woman. Said woman being a harmless pacifist who has never done a thing to him.
And he also murdered Ben Reilly, a person that Peter regarded as his brother.
Buried old and weak Aunt May alive. After that, he hired an actress to play May for Parker and killed her to hurt Peter. Why? So he could kill Aunt May twice in front of Peter. At the end, two times is better, right?
He also tried to kill Mary Jane in the same way he murdered Gwen Stacy, hoping that Peter will get mad by losing his love twice. Peter managed to save his wife, though.
And he topped himself again during his time as Director of the Thunderbolts and then during Dark Reign. Where he proved that even when he's sane (relatively speaking), he's still a monster, though a bit more charismatic than his Goblin persona. One particular moment stands out: after the Thunderbolts have captured Songbird, Osborn orders the Headsman to work his magic on her — he wants to mount her head on his wall. He also tells Scourge to film the execution for him so he can masturbate to it later.
And in a Spider-Man tie-in to Dark Reign, American Son, he topped himself again by seducing and impregnating his son's girlfriend, ordering her to tell Harry it was his child in order to make him join his team so he can get killed, making Norman more appealing to the public as a tragic figure.
This list is not even a half of Norman's "achievements".
Carnage, who was never really sane to begin with. As a child, he killed his grandmother and pet dog, tortured his mother, killed the headmaster of his orphanage with a lead pipe, and then burned the orphanage down, and pushed a girl he had a crush on in front of a bus because she rejected him; he became even more insane and murderous after bonding with the symbiote, and he has no qualms about who he kills...even people he once trusted, including his own henchmen and childhood friends. It's creepier when he gives a monologue about how the managers of the supervillain asylums are WORSE than him - and he's completely right.
Spider-Man Noir, an Elseworlds-style reimagining of the Spider-Man mythos, has several. Norman Osborn is now "The Goblin", a gangster/loan shark/strike-breaker/whatever you can afford who is possibly even more ruthless and evil than his mainstream counterpart. The Vulture is one of Osborn's lackies, a former carnival geek with a taste for human flesh and a preference for eating his victims alive. Later, the Noir version of Doctor Octopus is introduced, as a sociopathic scientist with Nazi sympathies who performs horrific experiments on the "lesser races". All come with a good dose of Nightmare Fuel as well.
Well, the Noir version of Norman Osborn is actually more sympathetic than the mainstream one. He is an embittered former carnival geek as well, with his real face looking like the Goblin mask. The mainstream Osborn doesn't have the benefit of such a Freudian Excuse. Doctor Octopus, though...
Redstone from the Supreme Power comic series. Invulnerable, superstrong, heat vision, and he uses it to kill innocent bystanders in the most horrifically graphic ways imaginable. He tears off limbs, hurls cars, boils people in swimming pools with his heat vision, threatens Los Angeles with a nuclear bomb while having the most pleasant facial expression imaginable. No wonder Hyperion wants to kill him. Essentially, Superman without a conscience and with an extremely violent and depraved personality before gaining his powers. Redstone kills with such reckless abandon because he feels, for the most part rightly, that there's nothing anyone can do about it. Thankfully, he's wrong, but...yikes.
Karla Sofen, aka Moonstone, of the Masters of Evil and a founding member of the Thunderbolts. As a psychiatrist, she was able to manipulate the original Moonstone into giving up his power source and would convince her patients suffering from depression to kill themselves in front of her. Later, she impersonated Ms. Marvel in Norman Osborn's Dark Avengers, and it was revealed that Karla killed her mother in order to prevent her from learning that she was a villain. Carol Danvers, the actual Ms. Marvel, forcefully took the power source from her in a duel, knowing that Karla wouldn't be able to survive if it was away from her long. She gave Karla an ultimatum: redeem herself or die. Carol placed the moonstone at the grave of Karla's mother in hopes that she would redeem, but later, Karla took back the moonstone and destroyed her mother's grave marker.
Kynkos, the son of Ares. He is first introduced in a flashback in The Incredible Hercules when Hercules found him building a temple for his father...out of human skulls. He returns in Dark Avengers: Ares and tries to kill his father to take his place. And eat his dead body alongside those of the Mares - four demonic horses that are his half-siblings, and make himself a crown out of his skull. Even Ares was utterly disgusted by this guy.
Kynkos, having stabbed one of Ares' men in the head with a spear: It appears I am to be Christian Saint too. For I have become a fisher of men.
Like Magneto and Deadpool, Galactus' Ultimate counterpart, Gah Lak Tus, is much, much more despicable. Instead of killing planets to survive and being able to be reasoned with, Gah Lak Tus is a swarm of drones who are repulsed by organic life and destroys entire inhabited planets to exterminate them. It first drives populations of creatures insane, so a good number of them kill each other before Gah Lak Tus even reaches there.
The Hand is an entire cult of monstrous ninjas whose leader is a literal demon called the Beast. They also have a bad habit of resurrecting other Complete Monsters to recruit them, like Sabretooth, or worse, resurrecting good people and turning them into monsters via magic and Mind Rape.
Hybrid, the mutant son of a human woman and a Dire Wraith. He took to the lessons in evil and power that his Dire Wraith tutors taught him so well that his father (who had reformed out of love for Hybrid's mother) feared that he was worse than his fellow Wraiths. Since the Dire Wraiths are a race of Complete Monsters, that's saying something. In his debut, Hybrid murders his parents, pits Rom and the X-Men against each other by pretending to be a helpless child, and tries to kidnap Kitty Pryde so he can rape her as part of his plan to breed an army of hybrids like himself. He also plans to do the same thing to all other female mutants. All at the age of fifteen. When Hybrid shows up again in Avengers Academy, he is just as evil and even more powerful.
Depending on the Writer, Doctor Octopus can be this. He is shown as a ruthless and evil scientist who wants to take over the world and is an arrogant person who sometimes betrays his own helpers and is responsible for the death of Captain George Stacy (though this was technically an accident; not like he cared about it though). One of his most monstrous moments is when he and the rest of Sinister Six invade another dimension and steal the highly-advanced weaponry they find there. And to test it out, they kill over 143,000 of that dimension's natives. Spidey himself is stunned, noting that the Six rarely, if ever, kill. Their bloody campaign continues when they return to Earth, killing at the bare minimum four dozen people (an explicitly given body count), and Octopus threatens to blow-up the world with orbiting weapon satellites if the assembled heroes don't stop fighting him. By the time it's over, a clearly soul-weary Spidey notes that way too many people are heading to the hospital or morgue. And another notable instance is in one story where he fought against Owl for control of New York City. Owl stole a neutron bomb from Kingpin and intended to use it to blackmail the city, but Doctor Octopus...In order to prove to the world that he was the most dangerous man on the planet, Doctor Octopus wanted to blow up THE WHOLE OF NEW YORK CITY, thus killing every man, woman, and ''child there, and he showed no regrets for it. Even Kingpin was afraid of him.
Robert Kirkman's short mini-series The Destroyer gives us Scar, Destroyer's Arch-Enemy. Among his crimes is cutting off Destroyer's wife's arm, so Destroyer will have to remember the day he couldn't save her every time he looks at her and gloating about the fact and that he ate that arm in his face, while holding his daughter hostage.
The Ultimate Marvel version of Reed Richards must surely count by now. He makes a deal with an alien empire to attack and conquer Earth. Given his highly idealistic views about improving a flawed world, this would ordinarily make him a Well-Intentioned Extremist. This doesn't apply since he also had his entire family killed, including his baby siblings, just so he could fake his death and avoid suspicion. After that attempt backfired and he was left heavily scarred, if anything he's become more puritanical, forming a highly advanced society of superhumans called the Children of Tomorrow. Under his leadership, the Children have absorbed entire cities into their base (including Berlin, Munich, Warsaw and Brussels), wiped out all but two of the Asgardian gods and, recently, turned Washington into a crater. The Children are mere pawns; Reed is fully aware of what he's doing, and feels no remorse for exterminating what he judges to be an inferior species. Maybe he once had a point about making the world a better place, but this idealism has wiped out a race of beings, several cities and billions of lives. No society can be worth that.
The Void, The Sentry's second personality, that not even Thor could take down, might very well be the single most powerful anything in the entire Marvel multiverse. He is concentrated evil and darkness that loves to torment people with tentacles that cause them to live out their worst fears in horrifying detail while usually committing mass murder whenever he gains control of Sentry. Norman Osborn called the Void "The fucking Angel of Death".
