Complete Monster/Criminal Minds

Season 1
"Karl Arnold: And I watched them, for a number of days, always at night. Saw how they lived, how they loved. I would keep them apart, until the last night, until the last supper. Then I would bring them, one by one, down to the basement, the youngest first, father last.....
 * Karl Arnold in "The Fox" would break into houses, take the family residing there hostage, and live with them for several days before stabbing the children and mother to death and shooting the father, making sure to show him his dead family right before killing him. Additionally, in "Outfoxed", it's revealed he actually beat the male children and raped the female ones, and that The Reaper is his pen-pal. He also used his position as a family psychiatrist to gain their trust. Oh, and when the FBI finally caught him, he threw a baby at them.
 * And why does he do this? His wife left him, taking their kids, because he was too much of a control freak, so he does what he does so that the families can see what happens when the father isn't "strong", like him, and kills the father last just to rub that point in. In his own mind, his controlling nature was a sign of good parenting...and he slaughters other innocent families to prove it.

Morgan: But why, Karl?

Karl Arnold: So he could see what happens to families when the head of household isn't strong... wives wither... children perish... but me? I'm an excellent father."


 * Jacob Dawes from "Riding The Lightning". A sexual sadist who killed upwards of eighteen girls with carpentry tools, he takes pleasure in taunting the families of four of them by refusing to reveal where their bodies are. He was so wretched that his death is a CMOA for a main character. He acts incredibly smug about knowing where the bodies are and the FBI having no clue. Then, as he is being strapped to the Electric Chair, Hotch lets him know that one of his victims (his wife's son that he ordered her to kill) is alive and well and he was fooled and betrayed by his partner and never realized it. The look of anger and defeat on his face as the hood is pulled down is beautiful to watch.

Season 2

 * Carl Buford from "Profiler, Profiled". Utterly unrepentant and didn't see himself as doing anything wrong. He also pretends to be a humanitarian. And he molests children, . He also murdered at least 3, with one being to frame Morgan.
 * Charles Holcombe from "Legacy". He views homeless people as subhuman specimen who should be exterminated. So he kidnaps them and brings them to his torture chamber, where he puts them through agonizing physical and mental torment before dissecting them alive. And he's been doing it for a very long time. He even gives them the opportunity to escape by telling them they can leave if they make it out in a certain amount of time (and even if they manage to do it, he knocks them out with gas to avoid their escape). In the end, he is shot and killed by the BAU and one only wishes he had suffered more. Also, his last words? "Just let me do my job!" Irrepentant, smug, and cruel until the very end.

Season 3

 * Floyd Feylinn Ferell from "Lucky", who killed women after forcing them to eat his previous victims' fingers and
 * Before the next example mentioned below, there was another criminal who went by "the Reaper", Glenn Hill from "True Night". His screentime totals to twenty seconds tops, but in that time, we see him order his street gang to rape a pregnant woman to death while he forces the woman's fiance to watch and subsequently attempting to eviscerate the fiance. Why? No reason given, one assumes they were just in the mood to do that that night and simply went with the first people they encountered. The twist? He's the episode's victim.

Season 4

 * The Reaper. Dear god, the Reaper. That man is Nightmare Fuel personified. His bloodied evil grin at the end of "Omnivore" will haunt you in your sleep.
 * Let's go into a little more detail on why he deserves to be on this list. He disappeared years ago after a long, unsolved killing spree (his last victim was, allowing the Reaper to disappear without casting any suspicion in the right direction). After returning, one of his first acts is slaughtering a bus full of passengers, and although he's caught at the end, he escapes due to memorizing the layouts of every prison he might be sentenced to. Then he goes after Hotch personally, stabbing him in painful, non-fatal ways as a form of torture (and there may also have been a sexual aspect to the torture we didn't see). It gets worse, as then he goes after Hotchner's family - . The Reaper is acknowledged as such a Complete Monster in-universe that, when she hears the end of the tale, Strauss, who is leading an inquiry into the events in which she has repeatedly tried to implicate Hotch in some way, is shocked and lets him go with her full condolences for what he's gone through.
 * Rossi deduces that he is also sexually aroused by teenage girls and by torturing them, because when they are his victims, he usually takes his time before killing them.

Season 5

 * "Mosley Lane" gives us Anita, the creepy old lady who grew up in a funeral home and has her husband kidnap young children for her to raise as her own. When the children get either too old or too troublesome, she has her husband Roger dump them in the crematorium out back. They're considered by fans as the worst villains in the series, even worse than the Reaper. Anita is the far more evil of the duo, even molesting several of the children on top of beating them. She's the one who does the burning too. One of the first children she took, Charlie, has developed Stockholm Syndrome, which Anita uses to make him snatch more children for her.
 * "A Rite of Passage" has two, Omar Morales and . Morales is a sleazy Mexican Mafioso who enjoys dismembering bodies and sending bits of them to the victim's family. , the unsub of the episode, murders helpless illegal immigrants with a machete as they Run for the Border, and while it's possible racism may be a factor, it's far more likely that he simply enjoys killing and targeted illegals because they're not supposed to officially "exist" and he could therefore get away with it. He also

Season 6

 * from "25 to Life". Not only did he stab Carrie Sanderson and her little daughter Abby to death, but also managed to  He also killed another woman to satisfy his psychopathic urges that he couldn't manage to keep hidden anymore. Unluckily for him, this last murder puts the BAU on his tracks. He's also a.
 * Lucy, from "Supply and Demand" is a rather different sort of monster from most of those on this list. The head of a human trafficking ring, Lucy has her gang kidnap young men and women and pimp them out to snuff film aficionados and other sexual deviants, staging live shows in which the victims are tortured, and even killed, by her men and/or clients. The victims are beaten, drugged, and otherwise mistreated to ensure compliance, and are kept caged in between visits from Lucy's clients. A psychological sadist, who derives gratification from being in control, Lucy frequently has her men lock in her in the cages, so that she can enjoy the victims' terror and win their trust while pretending to be a fellow victim; she takes unholy glee in revealing that she is, in fact, the one in charge. She's also the one who scouts the victims out in the first place, visiting college campuses, while posing as a student, and then staging her own abduction alongside any students she has befriended. When Lucy discovers that Renee Matlin, one of her victims is an undercover cop, she proceeds to play a game of Russian Roulette with her, then has the other woman savagely beaten, gloating the whole time. Interrupted by the police, Lucy manipulates Max, her right-hand man into being killed by them, planning to frame him for her crimes. Found out by David Rossi, Lucy's last act is to pull her revolver and try to blow him away.

Season 7
""What I did to your daughter, you can see on this tape. ""
 * Just two episodes into the season, "Proof" gives us the truly unique Cy Bradstone, an utterly horrifying Serial Killer who tortures and kills women who in ways that destroy their senses, at one point pouring sulfuric acid down a girl's throat. The reason he's truly unique is that he's mentally disabled, having been deprived of oxygen in the womb, and unlike the similar UnSub in "The Uncanny Valley", this isn't played for sympathy at all; on the contrary, it's mentioned that although he's disabled, he's smart enough to know that his disability means people will be more likely to trust him and uses that as a lure to snatch more victims.
 * He tries to rape his own niece because she reminded him of his first victim. He's also a raging sadist who injures women out of misogyny and is absolutely gleeful when he tells his brother what he's done. He's not a handicapped man taking out his anger on the world. He's a sadistic psychopath who happens to be handicapped.


 * Randy Slade from "Painless". A teenager with a very bad case of god complex, whose sociopathic tendencies weren't noticed due to his school achievements. One day, he walked into the school cafeteria, where he dared everyone to look at him, shooting them if they didn't. He then killed himself with a bomb that caused even more victims.
 * Clark Preston from "A Thin Line", a crooked real estate developer who hires crooks to commit crimes in neighborhoods so people will leave them and he can buy up their property dirt-cheap, not caring about who gets hurt in the slightest. He only gets worse from there. He starts a mayoral campaign, having his faithful toady murder entire families (including a baby in one case) and pin it on innocent black and Hispanic people to add fuel to his blatantly racist campaign platform. Fortunately,.
 * Malcolm Ford from "The Company", the man that kidnapped Morgan's cousin and kept her hidden for eight years. He not only abused Cindy sexually, he brainwashed her into being completely submissive to him and only failed to keep her beholden to him by locking her son away from her. He's manipulative enough to know exactly how to handle the FBI, as well as using an entire network of men just like him in order to flee the state.
 * from "Foundation", who abducts little boys, rapes and tortures them for years on end, then, once they get too old for him, murders them by burying them alive. Not to mention the.
