"Jesus, Krieger. You're still taping bum fights?"
"No. Now I'm into something... darker."
Sterling Archer and Algernop Krieger[src]

Doctor Algernop Krieger[1][2], also known as Dr. Krieger or Krieger, is a main character, and was the head of the ISIS Applied Research Department up until the end of Season 4, as a result of its dissolution. He goes by the title of Doctor and performs many activities that require a medical degree; however, he is neither a medical doctor nor "the other kind" ("technically"). There is some debate about Krieger's true first name. It may actually be "Doctor" or "Docter."

He is trilingual as he speaks fluent English, German, and Portuguese.[3] However, he appears to have little or no exposure to modern street vernacular; for example, he misunderstands the phrase "tight" to mean "confining," rather than "very satisfactory," as intended by the speaker.[4]


Dr. Krieger is characterized as both friendly and possibly insane. He is sadistic, calculating, manipulative, yet somehow decent and good-natured at the same time.

He has incredibly dark tastes in entertainment, having indulged in taping bum fights, experimented with mind altering substances on human subjects, and even using himself as a test subject in his own experiments.

Additionally, Krieger could be described as something of an otaku, having an interest in Japanese anime girls and being in a relationship with an AI holographic fantasy girl of his own design. He has been known to enjoy incredibly graphic Japanese tentacle porn, being acquainted with a number of titles and their sequels.

Krieger appears to have an interest in helping people when possible, but typically goes about doing so in incredibly immoral and amoral means. A notable example of this being when he restored Ray's lower body functions, but only did so after drugging him prior to being given consent. Despite his reputation, he appears to be the nicest person compared to rest of his coworkers.


Krieger was raised by a former Nazi scientist who fled with him to Brazil, where they lived until Krieger was 15, when his pet Dobermans killed the man he believed to be his father - this in reference to the book "The Boys From Brazil". It is heavily implied that Malory Archer somehow set these events in motion as he remembers her arranging for him to be brought to ISIS afterwards. Krieger studied and became accomplished in a variety of different sciences including bionics, electronics, neuroscience, chemistry, biotechnology, surgery, and robotics, but, despite this, never earned a formal doctorate degree of any kind or even attend med school which is sometimes evident in his conversations where people ask if he is a doctor.

In New York, Krieger lived in a run-down, "transitional" neighborhood which allowed him to focus his salary for "pet projects." His apartment is only shown once and is full of strange and disturbing items, such as a skin-colored wet suit and jars of human remains.

He was in a relationship with Cheryl Tunt, which he sustained by giving her doses of LSD via his "magic breath strips." His current love interest is his Virtual Girlfriend whom, Archer has been quoted as saying, "is so real that the state of New York is allowing him to legally marry her."[5] Unfortunately, their marriage was forced to be called off indefinitely (she was destroyed by Lana in the next shot, although later reprogrammed).

In season 5, Krieger encounters three cloned versions of himself and finds out they have created a nerve gas missile. In the next episode, a fight breaks out and one of the clones is hit in the head with a fire extinguisher and falls off the launch escape system. The next clone is shot to death and finally, both Krieger and a clone fall off the platform. After years of comas and no real screentime, in Season 13 Episode 5. Out of Network it is finally hinted that the surviving Krieger is in fact the clone. While Cyril, Ray and Krieger are talking over IIA's surveillance camera hack, when Cyril is whining about them all needing therapy to which Krieger replied "I Was born Well adjusted! The scientist's made sure of that." being his answer to therapy. Before the Coma, Kreiger constantly implied he may be a clone by not remembering Katya, forgetting their names, and being shocked when Cheryl called him a clone. Now he remembers the people that helped make him somehow, leaving our true blue cooky korvorkian laying incinerated somewhere in the waters of San Marco.....if in fact "Mole Hunt" Krieger was the actual 1st generation Krieger.

Hitler Connection

Malory has also implied that Krieger is a clone of Adolf Hitler, although Krieger has pointed out that if he was actually a clone of Hitler he would look like Hitler.

Sexual Tastes

Krieger's sexual proclivities are more libertine than most people's. He has numerous sexual fetishes and is expert in many of them. Among the fetishes - or otherwise deviant behaviours - he has an intimate knowledge of, or keen interest in, are:

  • voyeurism - Krieger has set up camera's in each of the main characters homes, including the Tunt Mansion, as revealed in Reignition Sequence, many of which are in bathrooms and toilets.
  • cybersex
    • he has created a Virtual Girlfriend with whom he shares his kinks and (somehow) seems able to have an active, satisfying relationship.
  • German porn
  • Japanese tentacle porn
    • so much so, a whole episode was devoted to it.
  • collecting vibrators[6]
  • molesting food
    • he was revealed to be the notorious food rapist, AKA the "Pita Predator."[7]
  • bestiality
    • sexual relationship with his pig "Pigley Three" is implied as after holding a Geiger counter up to Pigley Three and it going off, he aims it at his crotch and says "that would explain… a few other things"[8].
  • bondage / BDSM
  • homicidal necrophilia
Pam: "I mean, how do you not murder her every day"
Krieger: "I do..."
Pam: [looks aghast to camera]
(S6 Ep10 - Reignition Sequence)
[However, this exchange could simply imply that Mitsuko is so infuriating, that she drives Krieger into a homicidal rage on a daily basis, leading him to murder her, and then restore her.]

Krieger frequently gets erections at seemingly inappropriate times, such as with his bum fights[10], while carving up dead bodies[6], when contemplating cyborg fights[11], or when he is just happy.[12] His recurring erections are a running joke in the series and serve to under-score his sexual function/dysfunction: they are either obvious to the other characters or pointed out when they go unnoticed. Unfortunately, he also sometimes has difficulty achieving erections under more 'normal' circumstances[11], which explains his various paraphilias.


In addition to his scientific research, Krieger has a variety of more harmless recreational interests. He is a certified diver and has a flesh-tone neoprene or human skin diving suit in his apartment.[12] He is an avid fan of rock music, and apparently is a fairly accomplished drummer, although he is unable to play Rush's "YYZ", which he claimed to be "impossible [as] Neil Peart stands alone."[12]. He claims that John Bonham, drummer of Led Zeppelin, was a pussy. He is also a fan of Creedence Clearwater Revival shown when Cheryl returns his CCR album collection after their breakup.[13] He is frequently shown to own less than legal vans, many of which have been damaged or destroyed throughout the series. All his vans have references to Rush albums, both in their names and the murals painted on their side. He bowls and plays poker with his fellow coworkers, and enjoys making personalized firearm modifications. He also does a one-man comedy improv titled "The Science of Funny."

Science Experiments

Krieger Clones

Krieger's clones

Doctor Krieger's scientific experiments satirically mirror those of Nazi scientists who evaded death at the Nuremberg Doctors' Trial by escaping to South America or continuing to work for the US Army's biological and chemical research division (Chemical Corps), either in the US or Europe. Free of morality, Krieger shares the same dubious moral character and agenda as his forebears, pursuing only the utilitarian goal of power and control - and his own sexual satisfaction.

His 'frontier' work operates in the same murky taboo and grey areas of science which include human experimentation(non-consensual), human and animal cloning, human-robot interfacing (cyborgs), biological and chemical agents (nerve gases and psychotropic drugs), advanced AI and robotics. Occasionally, he builds toys which combine his sexual interests with his engineering ones, eg. producing a mechanical grip (for erotic asphyxiation), and a 'defecation and/or ejaculation' ray, and "The Wheel" that causes an orgasm and which in his words "Once it starts, it Keeps going" like the name imlpies . He has built at least one useful creation - the world's most advanced Spy Car, has plans to marry his kinky holographic AI, and Virtual Girlfriend, Mitsuko Miyazumi, and states that his greatest work is his recreation of Katya as a cyborg in Reignition Sequence (s6e10).

His many experiments include the creation of:

  • a form of body armor tested (fatally) by intern named Chet.[14]
  • a sex-bot called "Fister Roboto", which is a fully integrated multi-fetish artificial being. Krieger says the best part about the sex-bot is that it learns. [15]
  • a Chokebot to choke Cheryl after she complains that his own hands were weak and childlike.[13]
  • 'Formula K', a compound that he tested on Danny the Intern, which supposedly turns subjects gay.[16]
  • Magic Breath Strips that were actually laced with LSD.[17]
  • Krieger Kleanse, an alleged tea for evading a drug test which was actually a hallucinogenic experiment,[18]used to successfully trick Ray, Pam, and Cheryl into drinking for experimental purposes.
  • the world's most advanced Spy Car[19](a definite James Bond (Q Branch) parody and perhaps the most useful creation).
  • a sexually functional Cyborg[12]based on Archer's mostly dead fiancee, Katya Kazanova (and hobo skin).
  • a device to channel and duplicate the pound-for-pound strength of an ant into himself.[20]
  • cyborg legs for Ray Gillette and a bionic arm for Conway Stern. Has bionic hands ready for Lana; all she has to do is: "Say the word." Till that time, they suffice as "jazz hands".[21]
  • an unspecified but (presumably) dangerous and unsuccessful projects involving Komodo Dragons.[22]
  • instructions for Barry Dylan on how to build a spacecraft capable of surviving re-entry into Earth's atmosphere.[11]
  • experiments on drug-induced amnesia on an unwitting Cyril, who calls Krieger a "fake scientist". Cyril is then revealed to have forgotten his parent's names because Krieger drugged him, but he couldn't remember.
  • creating two half man half pigs named 'Pigley' and 'Pigley II' respectively.
  • an irradiated pig named Pigley III, who eats people.[8]
  • a mind control chip that is so tiny that it can be placed into the head with a syringe, but is later revealed as a tiny sticker from a Lego toy in season five. It is unclear whether this is true or not, because it was said by what is most likely not the Krieger that everyone knew throughout most of the show, but one of the other clones[23]
  • a "Narco Submarine" that would be undetectable by the coast guard, but is stuck in Cheryl's indoor swimming pool. [24]
  • an aquatic creature whose eyestalk emerges from the hot tub of the secret spa, as seen in The Archer Sanction.
  • a (possibly) functional "pants shitting ray" device the' K-9000 Infrasonic Pulse Rifle' that utilizes the 'Brown Note' (revealed to Lana in s6e4).
    • an "Ejaculation Ray". In the same episode Cyril Figgis, through implication (13:32/21:09), reveals that at some point in time Dr. Krieger was working on such a ray. Success unknown. In Season 13 we see his work bear fruit in the form of "The Wheel" which causes non stop orgasms.
  • robot versions of each member of the "core group".
  • an advanced holographic AI which he was going to marry.
  • Turning Dr Spencer into a monster during Plastic Surgery experiments.


Dream Personas

After the events at the end of season 7, seasons 8, 9 and 10 see Krieger take the form of a dream persona:


  • The real life model for Krieger is Ben Brieger. This may have partially served as the inspiration for Krieger's surname.
  • Even though Krieger was shown in the first 3 episodes, he didn't have a voice until season 1 episode 4, Killing Utne.
  • In The Rock (s1e8), Krieger himself expresses that he doesn't know what tampons are.
  • Although it is spelled Krieger throughout the wiki, his name is spelled Kreiger on the ISIS 401(k) screen display in Jeu Monégasque (s2e11).
  • He seems to be one of the few characters who genuinely likes Archer. This may be because Archer generally treats him well.
  • He has $105,526 in his ISIS 401(k)[4]. Sterling also mentions that Krieger's salary is larger than the entirity of the ISIS office put together. Despite this, he lives in a run down neighborhood in deeply unhygenic conditions due to spending all of his money on "pet projects".
  • According to I.S.I.S. employment records, his legal first name is "Doctor."[4]
  • Krieger himself has admitted that he is neither a medical doctor (MD) or an academic doctor (PhD).[17]
  • As Krieger himself has mentioned, "Krieger" is German for "warrior."[3]
  • He is an expert in manipulating the controls for the I.S.I.S. building, such as the elevator and the furnace (although he admits he has no idea how to run the I.S.I.S. worldwide radar system). He is also very good at improvising devices from scavenged equipment.[10][11]
  • Pam Poovey has sarcastically called Krieger "Clone Wars," after she discovered that he was a possible genetic clone of Adolf Hitler.[3] This is a reference to how the Clone Troopers in the Star Wars series were created by using a genetic sample from Mandalorian bounty hunter, Jango Fett, clone host and adoptive father of bounty hunter Boba Fett.
  • The door to Krieger's lab is apparently from the Panzerschiff Admiral Graf Spee, as stated in Legs. Though resistant to handgun fire and protected by electronic locks, it is vulnerable to rocket launchers and C4. Further, his lab is directly connected to the HV/AC duct, into which he has positioned nerve gas canisters.
  • Krieger says he is not a "serial" killer, although he put emphasis on the word "serial," implying that he is a killer. He is an expert at disposing of bodies and is completely callous both about the deaths of his colleagues and the act of putting bodies in Dumpsters.[12][6][21]
  • Throughout the series, as another running joke, he often shouts "Me, too!" in odd circumstances, for instance in reference to making his own aforementioned breast milk,[14] when Pam tells Archer to give his mother a hug as a thank you for his Dodge Challenger Special Agent Edition birthday present, he says no, and then Lana states, "Oh, God! He's got an erection!" [19], when Archer tells Woodhouse he would sneak up on him in his sleep if he wanted to see his bare feet[14], when Trinette says Seamus has a full diaper[14] and when Ray says he "piss[es] and shit[s] in a plastic bag".[21] This joke had fallen into disuse as of season 4.
  • Krieger encounters three clones identical to himself in appearance, habits and personality in San Marcos. Following a fight that resulted in three of the four Kriegers dead, it is ambiguous as to whether or not the surviving Krieger is the original of the group or one of the three clones, the identity muddled by being aware of Cheryl's "microchip" yet seemingly "forgetting" his co-workers names, which he originally attributed to a concussion, which is alluded to after forgetting A.J. Whom he met AFTER the fight; although this might point to it being something more serious and permanent. This seems to be a reference to the film The Boys from Brazil, in which 94 genetically identical clones of Adolf Hitler were created by Joseph Mengele.
  • As Krieger and a Krieger clone struggle at the top of the rocket, their shirts are oppositely buttoned. The Krieger that survives has the same button side as Archer's Krieger.
  • Having Krieger switch from a bowtie to a regular tie after his fight with the clones is often cited as proof that a clone took his place. However, Krieger has always only worn regular long neck ties throughout the entire series. The first time we actually see Krieger wearing a bowtie with his labcoat is in the episode Archer Vice: Palace Intrigue: Part II. This was likely given to him by his clone brothers to wear, since he was only in his underwear when they kidnapped him. When he's talking with his clone brothers at the beginning of the episode he is still in his underwear, but later in the episode he is wearing his normal lab clothes, except with a bowtie. Krieger's comment that "This regular tie means nothing. I don't like bowties, so I switched." was perhaps added to give the viewer some doubt if it was actually the real Krieger.
  • In Season 6, Episode 7 : Nellis, a pair of Aliens with mind reading powers address him by the name "Algernop", which would imply he is the true Algernop Krieger, and not one of his clones. Furthermore, after the fight, his first concern was to abort the missile launch (like the "true" Algernop Krieger wanted).
  • As a running joke Krieger reacts to something by screaming, "No, you maniac! You blew her up! Damn you! God damn you all to hell!" (Or some variation on the original line, such as, "They were goat feet. And you threw them out! Oh, damn you! God damn you all to hell!" in Pocket Listing.) This is an obvious reference to the final line from the 1968 film Planet of the Apes.
  • Krieger owns and operates a company called AlgerSoft which has a top secret website[25] which can be accessed by deciphering the various clues provided in Season 6 starting with episode 2 to obtain the username and password. Among the files available on the site include all of Krieger's research, some music and ringtones and surveillance videos inside of the Tunt Manor bathroom.
  • Although possible, he is most likely not a clone of Adolf Hitler because if he was, he would look like Hitler. For instance, Hitler was 5'9" and had blue eyes, whereas Krieger is 5'10" and has green eyes. But clones don't have to look like the subject that the are cloned from. The first cloned pet was a cat named Carbon Copy, a brown tabby and white domestic shorthair but they were cloned from a calico domestic shorthair. So they looked different, resulting from epigenetic re-programming, which is common in fertilized embryos before implantation. So Krieger may be a clone of Hitler.
  • He's no longer allowed near Abbiejean due to the agents believing that he was going to turn her into a cyborg although he was just making a robotic teddy bear and needed her height measurement.
  • Krieger may be based on Eduardo Krieger an ethnic German, Brazilian born physician, physiologist, Co-President of the 2014 World Health Summit, and President of the Brazilian Academy of Sciences.
  • In the code for the Algersoft website there is a comment saying "MADE IN GEORGIA :p". This is a reference to the fact that the series was created in Atlanta, Georgia.
  • In Season 5, Lucky Yates, the voice of Dr. Krieger, was added to the main credited cast. The opening title sequence was modified to include his name.
  • Krieger is the only member of the main cast to not appear as their human form at least once in each season they're in. This is due to the fact that he takes the form of Crackers every time we see him, in Season 9.
    • Though Pam is an alien in Season 10, she still makes several appearances as her human form, during Episode 9 of the Season.


  • "Me Too!" - Various episodes
  • "Smoke bomb!" - Various episodes.
  • "Also yes..."
  • "Yep Yep Yep!"
  • "Camera 1, camera 2, camera 3, camera 4, camera 5" - Various episodes.
  • "Bathroom 1, bathroom 2, bathroom 3, bathroom 4, bathroom 5, you know just my faves."
  • "You people would be amazed at what you do when you think that you're alone!"
  • "And god knows he's a little GILF."
  • "Uhp uhp uhp... Stop! My penis can only get so erect."
  • "Wow, this might actually work."
  • "Umm, that actually shouldn't be doing that.."
  • "It's a proprietary blend."
  • "For the love of God! Seal the exits!"
  • "I'm not a serial killer..."
  • "DANNY! Stop running Danny!!! We've gotta keep that heart rate down, buddy!"
  • "Sooo should I just start pumping in the nerve gas now?"
  • "It's Zed, and no... Neil Peart stands alone."
  • "No, you maniac! You blew her up! Damn You! Goddamn you all to hell!"
  • "That'll do, Pigley... that'll do."
  • "Sure, go ahead--get in there, Pigley; god knows you've earned it."
  • "Are you addressing me? Because your authority is not recognized in Fort Kickass."
  • "HIS MINDBRAIN!.. Shut up, that's a real thing."
  • "Well, there goes the frying pan theory."
  • "Jazz hands!"
  • "Just don't make any sudden movements, bowel or otherwise..."
  • "And by the way, if I was a clone of Adolf goddamn Hitler, wouldn't I look like Adolf goddamn Hitler?"
  • "Is it murder if they were my own clones? Because I'm seriously asking."
  • "Bullshit...the CIA doesn't have that kind of technolo grrrt!"
  • "Aktion!" (Action) when commanding various cyberbeasts to kill. ie. the robot Dobermans in the "Dreamland" season obey this command, which is an homage to the Boys From Brazil.
  • "Its the same principle!"
