Considering what happened to Dallas, no matter how deserved proves Luck is just as capable.
Fermet is very likely the crowning example of this trope when you consider that he got away with it toward Czeslaw for roughly 200 years.
Berserk had a creepy guy locking up Guts and Casca in the dungeon cell with Griffith, the guy they had come to rescue, and it turns out that he was responsible for Griffith's horrific year-long torture. Among other things, he slashed the tendons in Griffith's wrists and ankles, and even giddily shows them that he cut his tongue out and made it into a necklace. In response, Guts smashes through the door, runs him through, and cuts his own tongue out.
In Higurashi no Naku Koro ni, the small town of Hinamizawa has some dark secrets in its history, including a shrine storeroom loaded with medieval torture devices that were once used to discourage townspeople from moving away from the village. Sonozaki Shion puts the Sonozaki family's old-fashioned underground torture cellar to good use during her Freak Out.
Ibiki Morino in Naruto, although his preferred method is psychological torture.
Martin, one of the Aldaac terrorists in Train Plus Train. We get a detailed look at his tools, and he gets to work on protagonist Reiichi, tearing one of his fingernails out before making him give in. Oh, and he's like fourteen years old.
In the Yu-Gi-Oh! manga, Seto Kaiba's butler is a professional torturer... and an amusement park ride designer. These two facts are not unrelated.
Dark Malik is one too. He's actually a Combat Sadomasochist, and in the manga, he is getting off to this.
Feitan from Hunter × Hunter. Also, he is one of the strongest fighters in the series.
Davis from the Sin City story, "The Big Fat Kill," is described as an "artist" when it comes to torture, able to put someone through sheer agony without leaving a single mark on the victim, and it's implied that he's even nastier when the "tools" come out. We don't get to see what he does with the tools, because Dwight, along with all the girls of Old Town, pitch in to save Gail in a Big Damn Heroes moment. In the movie, Davis's role is handed off to Manute.
In Mark Waid's limited series Empire, the Evil Overlord Golgoth has a typical inner circle of lieutenants. One of them is the "Minister of Punishment", Tumbril, whose characterization can be summed up in one line:
Tumbril: I mean, you give me an enemy of the state, I'm good for an afternoon. I'd do this for free.
Subverted with Herr Doktor Kilikil in the Spirou and Fantasio adventure "QRN On Bretzelburg": his methods involve scraping chalk on a blackboard, or cooking a lavish and fragrant meal in front of a hungry prisoner. He's so good at it, in fact, that he eventually becomes a restaurant cook.
Batman villain Black Mask was eventually reimagined as such in the pages of Catwoman; he cites reading up on the Spanish Inquisition as an inspiration for him. In the same arc he once carved a man apart and force-fed pieces of him to the man's fiancé.
In The Darkness, there was an appearance by a nerdy-looking fellow, Mr. Vespasian, described as the ultimate torturer. He took out an odd, hooked and twisted blade and did something to his own arm with it — something that made hardened criminals gag and look away in horror. "Ow," the torturer said cheerfully. "That hurt." Then he leaned close to the man he was supposed to interrogate and added, "Now imagine what I'm going to do to you." The victim immediately spilled everything he knew.... (And then Vespasian's employer gave him permission to work the guy over anyway.)
In the Belgian comics Passe-moi l'ciel, Hell is full of this, with demons council always searching for new techniques.
But when Pinosecu's (mix of Pinochet and Ceausescu) torture officer is brought to Hell, he ended torturing the demons to show them how to do it better.
The Decepticon Justice Division in Transformers: More than Meets the Eye all fit this to some degree. Most of them transform into torture devices. Torture devices capable of inflicting unspeakable pain on giant robots.
Astérix the Gaul features a rather cheerful Roman torturer.
X-23 has been on both sides of this trope. As her primary purpose function has been indicated to focus on covert operations and assassination, she has revealed or hinted her experience at using torture to extract information, such as by describing her protocols for extraction of information in French class while going to school with her cousin in a Crowning Moment of Funny of Target: X, or being outright depicted using torture during her stint on X-Force or in her solo series. Her willingness to use these techniques often puts her at odds with her teammates.
Her Ax-Crazy handler Kimura has been frequently shown torturing Laura, her friends, or her loved ones (such as punishing Laura with a chainsaw for escaping), and this is clearly shown to be part of the job. Xander Rice did it as part of the process of preparing her as a weapon (special mention goes to conditioning her for the trigger scent, which involved waterboarding and electric shock), and while his treatment of Laura is clearly established to be Revenge by Proxy, the adult Rice is introduced in Innocence Lost in the midst of performing experimentation on mutants which ends with the death of one of the subjects. Malcolm Colcord also utilized torture on Laura and various random citizens of Madripoor during his attempts to resume Weapon X experimentation.
Psyklops, a psychic vampire working for the Dark Destroyer in Atari Force who feeds off pain.
Mr. Brass from Scalped is a particularly sadistic torturer.
Tortura from the infamous Power Rangers fanfic "Agony in Pink" is a monster created from books, reports and essays about torture, and is very good at it.
The leader of the thugs who kidnap Mike Stoker in the Emergency! fic "The Numbers Game'' (bottom links here) is one. He flat out says he wants to keep Mike alive and lucid until they're good and ready to kill him. And when he is finally rescued, his crewmates are horrified at the extent of the burns,cuts,beatings ect designed deliberately to inflict as much pain as possible without killing him.
Films — Live-Action
In Lethal Weapon, Endo fits this and is described by Joshua as "having forgotten more about dispensing pain than you and I will ever know."
In True Lies, Harry Tasker is not happy to meet the Torture Technician Samir.
What did this do to you? Tell me. And remember, this is for posterity, so be honest. How do you feel?
A few villains from the James Bond franchise qualify:
In Tomorrow Never Dies, Dr. Kaufmann and his protege Mr. Stamper have a whole torture system involving chakras, the point being to torture the person to death as slowly as possible. Dr. Kaufmann describes it as his hobby, and has a record of keeping someone alive during it for 52 hours.
Largo from Thunderball who claimed he could do horrible things with just a lit cigar and a bucket of ice cubes. We have no reason to disbelieve him.
Captain Vidal from Pan's Labyrinth finds torturing people disturbingly pleasant.
Brazil has Jack Lint, the white-collar government torturer pictured in the doll's head above, who brings his daughters to work and has a nice secretary to type out his subjects' screams. The role was Robert DeNiro's first selection, but Gilliam had already promised the part to Michael Palin.
In Kafka, as in Brazil, Ian Holm plays a frail functionary in a dystopian bureaucracy. He's ultimately hoisted by his own petard when one of his subjects breaks loose of his restraints.
The Evil That Men Do (1984). A hitman played by Charles Bronson is hired to murder Dr Clement Molloch, a doctor who advises South American dictatorships on how to torture people. The movie opens with Molloch demonstrating to a group of army officers the use of Electric Torture on a dissident journalist.
EV-9D9, Jabba the Hutt's torturer droid in Return of the Jedi. Somewhat subverted in that she only tortured droids.
In Three The Hard Way three gorgeous women on motorcycles show up to have a little fun with a mook that the heroes have captured. They have to leave him able to talk before they can have all their fun. One of the good guys notices the last one is carrying a closed shoulder bag.
Keyes: Can I ask you what's in the bag? Woman: Don't ask.
Dan from Zero Dark Thirty was a fairly ruthless one for the first part of the movie, though he eventually had enough and left to work at Langley.
Inquisitor Glokta from The First Law trilogy is not only one of these, but a main character as well...
Not just a main character, either, but a protagonist and, dare I say it, a decent guy compared to many of the characters. When you've got one of your foremost "heroes" routinely chopping off fingers and sending innocent people to prison camps, well, you know what state the world is in.
Semirhage in The Wheel of Time — She tortures people entirely by stimulating the pain (and sometimes pleasure) centers of their brains with magic. Formerly the greatest healer during the Age of Legends, she would extract a price in pain in exchange for saving people. When people finally caught on to what she was doing, she was given a choice: take a magical vow to never cause do it again, or be severed from magic forever. She Took a Third Option and joined the Dark Side. People were known to kill themselves at the mere mention she would be questioning them.
Various former Kings and Patricians of Ankh-Morpork count, though their tendency is only mentioned in anecdotes within the text. There's a (nameless) Torture Technician with the Cable Street Particulars in Night Watch, however, and Captain Findthee Swing probably qualifies too.
The Tickler in the band of Gregor Clegane tortures peasants to find hidden booty and track the movements of enemy bands. He asks the exact same list of questions of each person he tortures over and over again until they die horribly. Arya muses that not only is he asking the people questions they couldn't possibly have the answers to, he isn't even giving them time to answer before he keeps torturing them, suggesting he's ultimately just a sadist.
Qyburn is a former maester who was thrown out of the organization for conducting amoral experiments on living creatures, including vivisections. Cersei puts his knowledge to use as a torturer, among other things.
House Bolton gained notoriety over the years for flaying their prisoners. Their arms depict a flayed man, and they wear pink cloaks with red spots, indicating their old habit of wearing the skins of their adversaries.
Alongside the official Family motto of "Our Blades are Sharp" we have the unofficial "A Flayed Man Holds No Secrets" and derivatives said by more than one person affiliated with the House. Some traditions are very much alive and well, it seems.
In If This Goes On —, a science fiction short novel by Robert A. Heinlein, our hero is captured by the evil government. He notices that the several Torture Technician workers for the government show no pleasure in their job, they are strictly business. It is implied that anyone who likes to inflict pain is not permitted in that job, as they are supposed to get information, not necessarily hurt people (although that is always an option if they think it will help).
Bellatrix Lestrange of Harry Potter, having spent 15 years in Azkaban for torturing people into insanity and being described by Dumbledore as liking "to play with her food before she eats it." In book 7, while it's off-screen, she does torture Hermione, and, it's implied, not just with the Cruciatus curse.
Amycus and Alecto Carrow really love torturing people, including their own students.
Dolores Umbridge and her Blood Quill.
The Mord-Sith in the Sword of Truth series, who double as bodyguards. Uniquely, they are on the side of the "hero" (he effectively inherited them), after the first book. In fact, the first thing he did on taking power was order them to disband, but they decided to serve him anyway, on the reasoning that a man who would set them free was worth serving.
There's a gruesome variation in Franz Kafka's story In the Penal Colony: there's a torture machine that slowly carves a single sentence into a person and then lets them die for twelve hours, but it's being removed. The Officer, who works the machine and believes in it, asks to be the last person to use it and wants it to carve into him "Be Just." However, the machine malfunctions and ends up just brutally stabbing him to death.
Doctor Jest, the chief torturer of the Melnibonean empire from The Elric Saga.
Gene Wolfe's Book of the New Sun has the Weird Trade Union The Torturer's Guild which is an organization of these. Like some of the other examples, they are explicitly supposed to be unemotional and just doing a job, explicitly prohibiting those of a Psycho for Hire mentality. Moreover, they don't torture to extract information, only to carry out judicial penalties. It's their job to perform exactly the tortures decreed, and no more (or less).
I would argue they do extract information. They call themself the "Order of the Seekers for Truth and Penitence" after all.
There is a poignant scene where the now-Autarch Severian tells one of his former masters that he is dissolving the guild, not out of ethical qualms, but because it is intolerable that good men should devote their lives to inflicting pain. The master responds that "It MUST be done by good men"; should it be left to those who take pleasure in it?
In the jokes section of CASTLE OF THE OTTER, there is one about apprentices clumsily inflicting tortures because they are scared by the master yelling at them, until he demands "What are you trying to do? KILL the man?"
The YA novel Dragon Cauldron in the Dragon Series by Laurence Yep features a cheerful and hairy man who believes one should always do one's job well. He's hurt by being called a torturer and prefers the term "facilitator".
Sage Kindness in Scott Lynch's The Lies of Locke Lamora. His employer, Capa Barsavi, is said to be a very capable torturer, but when Barsavi runs out of ideas, Kindness takes over. And does so with the "mellow disinterest of a man polishing boots".
Dr. Alice Hong, the Lady of Pain, who mixes psychopathy with surgical skill in S. M. Stirling's Island in the Sea of Time series.
Barin Welachin from Jennifer Fallon's Second Son's trilogy served the Lion of Senet (the world's foremost ruler and religious nut) in this capacity. The protagonist, Dirk, has at one point to talk with him and, as part of the facade he has to put up, feins interest in the man's work. Barin is delighted to be able to share the joys of his craft to someone truly able to understand and appreciate it (Dirk was trained as a healer and had an, unwarranted, reputation as The Butcher of Elcast). The right hand woman of the corrupt and murderous (and dominant) segment of the church, Ella Goen, was also one of these.
Venus in Furs has a character that borders on this, though with lots of fetishistic overtones and more psychology-heavy. The author of this novel, Leopold Sacher-Masoch, is the inspiration for the word "masochism."
A minor, unnamed character in the pre-reviz Magic: The Gathering novel Shattered Chains tortures Rakel in many horrific ways—but he's not sadistic at all. To him, it's just a job. This, Rakel thinks, is worse than if he enjoyed it. To say nothing that they don't even want any information—a political enemy of hers just wants her to suffer before her execution.
You must learn to do your job coolly, officially — for the money. It makes an enormous impression on the victims of your inquisition. What an appalling state of affairs when you find yourself being tortured not by an enemy but by a bureaucrat. Take a look at my [missing] left arm. His Imperial Majesty's specialists sawed it off in three stages; and each order was accompanied by a lengthy official correspondence. Those butchers were just doing a disagreeable, boring, unrewarding job. While they were sawing off my arm, they cursed their wretchedly low pay. And I was terrified. I had to strain my willpower to keep from talking. And now... I can see how you hate me. You — me, and I — you. Fine! But you have been hating me less than twenty years, and I — you, for more than thirty. You, young man, were still toddling under the table and tormenting the cat.
The Dragon Willy Krebbs in Moonraker got his nickname "The Persuader" for always getting the answers from prisoners through torture.
Rosa Klebb in the novel From Russia with Love was a virtuoso Torture Technician, letting the pain of her torturers (she never actually did the work) build and build and build; then she would talk, softly and gently - being mother to her victims. "Tell mama and it will all be over." A chilling passage in the book indeed.
The title antagonist of Colonel Sun is a torturer in the Chinese army, who believes that a torturer and his victim can attain a special connection through pain.
Manipulative BastardYsanne Isard dabbled in this, using injections and machines that directly stimulated pain, heat, and cold receptors rather than dismembering people. One of the first things she does is use a drug that the protagonist thinks of as one that would have him reciting things his mother had forgotten while he was in her womb, but the real goal in mind is to set up her authority and prepare them to become Manchurian Agents. She also brought in a Trandoshan to do the grunt work of getting the protagonist in position, hooking him up, manipulating the switches and so on, because she knew his father had been killed by a Trandoshan.
The Gestapo torturers in The Secret Of Santa Vittoria take pride in their work, even taking time to explain that pulling-out-nails is overrated; electric torture is MUCH more effective.
Milovan Djilas historical novel UNDER THE COLORS has a prolonged torture sequence where the Turkish interrogator carefully explains to his assistant the name of each technique, where it came from, and what it USED to be called.
In the original The Phantom of the Opera book by Gaston Leroux, The Persian reveals that Erik (the titular Phantom) worked as one of thes for the Shah-in-Shah in Mazenderan. Help to explain a lot of things.
Arkadeil from The Acts of Caine. His matter-of-fact, scholarly manner of To the Pain arguably makes him far creepier than many who take sadistic joy in it.
Faith in Buffy the Vampire Slayer was also quite fond of torture - at one point, Angel complimented her on how well she knew how to do it. One wonders how a teenager knew so much about the five basic torture groups.
Angelus himself, the soulless version of Angel, an aficionado of physical and psychological torture (as he put it "The last time I tortured someone, they didn't even have chainsaws.").
'Aficiniado' is an understatement. Angelus could inflict pain on people, either mental or physical, like no other being in the Buffyverse. There were vastly more powerful, there were even some (if not many) more sadistic, but there were none as skilled.
There was also Marcus, the Roman-born paedophile vampire hired by Spike in an early episode of Angel to get the Ring of Amara's whereabouts out of Angel.
Willow as a vampire. Just...Willow as a vampire. She had Angel (described above) trussed up and slowly burnt alive as a form of sex play.
Adelai Niska has one in Firefly, although he's keen on getting hands-on himself.
Niska wasn't particularly attached to any one torturer. In his first appearance in "The Train Job" he used Crow, who was also The Dragon before the guy got kicked through Serenity's engine in a Crowning Moment Of Awesome for Mal. In "War Stories," he had to hire another torturer and Dragon.
Also, the Clark Administration interrogator, a truly chilling Punch Clock Villain, assigned to break Sheridan 2 + Torture = 5 style in "Intersections In Real Time." J. Michael Straczynski based that on actual prison camp/totalitarian regime methods. And also Sebastian for the Vorlons, who was based more on religious cult brainwashing techniques, but wasn't above physical violence either.
The former was also blatantly influenced by 1984: Sheridan is being held captive in a place without windows that makes it impossible to tell what time of day it is by a government that includes a "Ministry of Peace", an ominous "Room 17" is repeatedly mentioned, he is coerced to sign a confession of his crimes against the government and embrace the regime and his interrogator informs him that if he submits, he will be released, live in peace until he's forgotten then quietly killed.
A case could be made for Scorpius of Farscape, who gave us the scary-as-fuck Aurora Chair.
Unlike most torture technicians, Scorpius is remarkably strong- enough to force open one of Moya's prison doors with his bare hands. Well, gloved hands.
A more obvious case is one Selto Durka, who not only manages to fit this role like a glove, but knows it well enough to eventually break free of a hundred years' worth of brainwashing.
Gul Madred in Star Trek: The Next Generation fills this role for the Cardassians in "Chain of Command", even in a time when (as Picard protests) any usefulness torture once had as an interrogation technique has been made obsolete by the drugs they have available. He just likes breaking people's spirits.
In LOST, Sayid acted as an interrogator for the Iraqi army. He puts his torture skills to use on Sawyer in the first season, though he quits pretty fast and has generally sworn off such things. In a later season, Oldham acts as the DHARMA Initiative's torture expert. He's a folksy psychopath who lives on his own in the jungle and uses drugs that appear to be LSD as part of his technique.
Averted in 24 where the torture technician (I can't remember his name) seems to just treat it like a job, and in many cases appears to be less willing than Jack to torture suspects.
The TV version of La Femme Nikita features a male and female duo of disturbingly adept "white room" operatives. Often brought in at the behest of Madeline (who was an effective torturer herself), these cold-eyed techies got answers for Section One... and occasionally torture errant members of that group as well.
Star Trek: Voyager. In a propaganda holoprogram made about Voyager, the EMH is portrayed this way. The real Doctor is not amused.
Creepily enough, Dean, at least after going to Hell.
His "mentor" there, Alastair, also obviously qualifies. Alastair is in fact considered Hell's greatest torturer.
If Sam's flashbacks are anything to go by, Lucifer has a gift for this himself — not that that should be any surprise.
Crowley has a few on staff, but is more than skilled at it himself. He even has his own butcher's apron.
Very surprisingly, Castiel, who is blatantly hinted to be better in this art than even Crowley. Shocks both Dean and Bobby, Beware the Nice Ones indeed.
On Star Trek: Deep Space Nine, this was occasionally one of Garak's "jobs" in his past as a spy for the Obsidian Order. In "The Die Is Cast" a chance to return from exile made him willing to torture Odo, although the scene makes it clear Garak is hurting as much as his subject and deeply regrets his actions. Odo reveals his longing to return to his own people, paralleling Garak's own motivation. In the Mirror Universe, Garak is a brutal and notably unsubtle Smug Snake of the Torture First, Ask Questions Later variety.
On Good Eats, there is the Dungeonmaster, who lives in Alton's basement. He shows off more advanced cooking implements, and is not above tormenting bunnies and such. Alton doesn't particularly like him.
In Merlin, Alator of the Catha is a skilled torturer, although he takes no pleasure in it. He uses a form of magical mind-torture which is extremely painful and efficient but apparently leaves no lasting physical or mental damage.
Janina Kleiberson from Dracula, in a rare case of this trope being played out by a woman.
In the 1980s V series, Diana is basically a Mengele-Expy with her medical "experiments". She's also the head interrogator of the Visitors and responsible for brainwashing people to serve them against their will. She insists on carrying out the Mind Rape herself specifically because she enjoys it.
George King, "The Skinner" from Dexter used to be a torturer in Nicaragua with the nickname "The Blade". In present day, he's a serial killer who still tortures his victims for information, though Dexter points out that he really just does it because he enjoys it.
Hunter: The Vigil has the Malleus Maleficarum, a refined branch of the Inquisition that really does not have much mercy to spare for supernatural creatures. Your character can be one of these with the Torture Suite Merit, which adds a bonus to interrogation attempts.
Warhammer 40K has this and has it done to its Illogical conclusion. Dark Eldar Homonculi are Torture masters whose skills are so good as to make them highly dangerous warriors. Seeing as the Dark Eldar have to torture mortals to survive their entire race may well touch on this.
The Dark Angels and their successors have Interrogator-Chaplains, who serve as a sort of internal security as well as torturing any captured heretics into repenting their sins.
The Inquisition have Torture Technicians raised from birth in the "art" of torture - woe betide any unrepentant heretics. The Inquisition even has a several-stage routine for torturing people; the first step is telling the victim what the rest of the steps are...
The Night Lords legion of Chaos Space Marines wear this proudly as their Hat along with being The Dreaded even before they turned traitor.
Revolver Ocelot (or just Ocelot when he said this) from Metal Gear Solid. "You know, it's not all that bad...it's the ultimate form of expression." This was in Metal Gear Solid 3, after seeing Naked Snake with one of his eyes bleeding from having a muzzle flash destroy it.
He was inspired by Volgin, who, hilariously, is an absolutely horrible torturer. He's a sadist, and either kills the subjects, or ends up giving them more information than he gets.
When you enter the interior of the thieves' guild in Baldur's Gate II, one of the first people you'll see is the house torturer and his squeamish child apprentice, the torturer trying desperately to impose some manner of love for the art in his successor, who ends up running off sobbing whenever he gets to the good parts.
In Heroes IV, the Necromancer Castrata is described as having a collection of rare and ancient torture devices, along with written confessions of those she tortures.
In Knights of the Old Republic, you run into droids with this specific purpose. Furthermore, in the sequel Atton Rand reveals that he used to be one for the Sith, torturing and killing Jedi.
"There's ways of gassing them, drugging them, making them lose control, torturing them. I was really good at it. What's worse, is that killing them isn't the best thing. Making them fall...making them see our side of it, that was the best."
In Liberal Crime Squad There is a Psychology skill. A higher Psychology skill means that the character was better at "enlightening" kidnapped conservatives. That means you can train and employ torture technicians.
Bayonetta has aptly named "Torture Attacks" when she has sufficient magic in her magic meter that she can use to dish out more pain (and higher combos) against her angel enemies. Spiked iron maidens, pulled through a chain winch, crushed by two giant hands, and that's just the tip of the iceberg.
Shin Megami Tensei: Strange Journey has the demons of Bootes, who have captured several humans and are subjecting them to nightmarish tortures. The reasoning? They're trying to find out just how much of the material body is necessary for a human to survive. That the answer is "all of it" doesn't satisify them.
"When we cut into the human's skull, a gray material leaked out of their skull, and they stopped moving. Our conclusion is that humans need something called a 'brain.' But in hindsight, we've created a person who can never get angry. We've done a good thing! What a good thing we demons did!"
In the opening act, the player character ends up passing through a torture chamber staffed with torturers that are part of the Imperial Legion.
The Thalmor are the GODS of this trope, as demonstrated quite vividly during the Diplomatic Immunity quest. Their First Emissary and ambassador to Skyrim, Elenwen, is particularly skilled in the art of torture, such that other emissaries and associates will often have her evaluate their technique. And one of her most prominent victims? Ulfric Stormcloak.
In Diablo III, the Inquisitors of the Templar Order are essentially this, in charge of "cleansing" new initiates of their sins by beating and whipping the living daylights out of them. They don't particularly give a damn about the guilt or innocence of the initiate, and will gladly pile false sins upon an innocent if they feel he would make an asset to the Order, as happened with Kormac, your Templar follower who was put through this.
Deconstructed with the interrogator for the Damned 33rd in Spec Ops: The Line. Far from being a sadistic maniac, he was tortured himself…and cracked, just like his victims. "We will be like brothers," he writes, "Having stared down death, and flinched."
Dr. Vahlen of XCOM: Enemy Unknown is a rare heroic case. Part of her job is to interrogate captured aliens. While her motivations are noble - the defense of Earth - she does seem to take a certain pleasure in her work. For that matter, none of her subjects have ever survived interrogation.
In The Chronicles of Riddick: Assault on Dark Athena, an unseen member of the Athena crew occasionally referred to as "The Dentist" is strongly implied to be this. Being sent to him/her is considered an extreme punishment, on par with having your body harvested into a mindless cyborg. One seasoned merc is willing to face the One-Man Army that is Riddick when Revas threatens him with a "trip to the Dentist". Earlier in the game another merc can be overheard joking about it, and his partner immediately shuts him up with a sincere "Don't even fucking joke about that".
Wanda from Erfworld is known as one of these... Well, it's her hobby at least.
Dellyn Goblinslayer in Goblins is a sadistic fantastic racist who captures monsters, then vivisects them in order to learn their weaknesses. His favourite possession is the 'Finger of Hell', a knife which he designed himself in order to inflict as much pain as possible on goblins, who he reserves a special hatred for.
Terrence in KateModern, especially in "Answers". It's hardly his official position, but at least he has fun.
Dusk Peterson's series The Eternal Dungeon, where prisoners are respected, the truth valued, and confession is considered necessary for the health of the criminal's soul. In the first book the main character is sent to the Eternal Dungeon after being accused of murder. The series continues with him after he has himself become a Seeker (Torture Technician).
Web-writer Cor's unstoppable tickle "monsters".
Captain Jarvis from The Return is a scarily efficient emotionless Torture Technician and is one of the good guys* Irony being what it is Jarvis becomes a lot less scary and emotionless after being turned into a demon!!! Yes, this is a Grey and Gray Morality series.
Dr. Moon from Justice League Unlimited wasn't allowed to get too graphic, as per the censors (not that that's necessarily a bad thing), but seemed to be Cadmus' go-to guy for extracting information with a combination of Electric Torture and implanting images directly into the victim's mind. Incredibly, The Question manages to take the scene and play it for laughs.
Interrogator: Tell me what you know!
The Question: The plastic caps... on the ends of shoelaces... are called aglets. Their true purpose is... sinister.
Supposedly Cyclonus of Transformers Generation 1 is one of these, as Galvatron mentions how much he loves watching Cyclonus carry out an interrogation. The only time we see him do this he's merely whipping someone and since he's actually Starscream in Cyclonus' body working with the interogatee to give Galvatron false information, he's deliberately missing.
During its military dictatorship, Brazil exported torture technology.
Brazil is not alone in this. at the time British Prime Minister Tony Blair was calling for the British military sales industry to be more ethical, it was revealed British companies were exporting "police and internal security equipment" that inexperienced eyes might mistake for torture equipment. End users of "restraint and detention" equipment included Israel, Saudi Arabia, other Arab states, and various Far Eastern and Central/South American states - all of which were on Amnesty's list for human rights abuses. A year after Blair's call for more ethical sales, British makers were still attending international arms fairs marketing the world's best detention, restraint and interrogation equipment.
