"A story in which a man with slicked-back hair and a thick German accent is going to create a new lifeform — or "Master Race" — of blond Caucasians who will swear allegiance to him, and only him, all underscored with a hymn by Wagner. Clearly, this is about Vietnam!"
Bleach has the Wandenreich, an organization of Quincies whose abilities are given a German motif. They even take their cues from the Teutonic Knights and Knights Templar on account of having a strangely Christian vibe with their crosses and angelic motifs with their Letzl Stil/Vollstandig. However, special notice has to be given to two specific members - Quilge Opie and Yhwach. The former is a Drill Sergeant Nasty whose idea of recruiting people involves murdering them until they fight back, compounded by the fact that he looks like Heinrich Himmler and displays a distinct Lack of Empathy to the "weak". The latter is The Emperor of the Vandenreich, who enacted The Purge on all mixed-blooded Quincies - no further comment necessary.
Nishikori in Cage of Eden is explicitly referred to as using Nazi tactics. However, in a rare example, they are not talking about genocide or racism (the population is too small for that). Rather, he borrows the Nazi "whistleblowing" tactic, encouraging his slaves to report on each other. Not only does it keep him informed, but it keeps his followers scared and unable to cooperate against him.
Britannia from Code Geass combine Naziism with the British Empire, with a society built around notions of social darwinism. They refer to conquered non-Britannian people by a numbered designation ("Elevens" instead of Japanese) and are not hesitant to massacre entire ghettos in order to fulfill their aims. They also pull off the political rally with Charles Di Britannia turning Clovis' funeral into a political rally complete with All Hail Britannia chants. It also borrows from Japan itself with the Numbers being a reference to the Japanization that happened after Japan began expanding its borders.
There is a Purist Faction and what they stand for (i.e. Blood Purity and Pollution theories). At one point, Euphie is convinced to overlook an apparently talented painter's work due to his having a smidgeon of Eleven blood.
Done comedically in with organization ACROSS in Excel♥Saga. Characters regularly shout "Hail Il Palazzo" while doing the Roman salute to their leader. Though otherwise ACROSS does not share much with Nazism, besides a desire to Take Over the World.
In the anime you can actually briefly see twin swastikas in Excel's eyes as she vocally expresses her loyalty in the first episode.
Amestris, the country in which Fullmetal Alchemist takes place, is a military nation where the standard — or you might say, the preferred look is blonde hair and blue eyes, ruled by a "Führer" who in the past sought to exterminate an ethnic group living within the borders, distinguishable by their facial features and monotheistic religion. Amestris is, however, rather more like post-WW2 Germany, what with the aforementioned "Ishval Civil War" having been a horrible PR catastrophe and most modern Amestrians behaving extremely apologetically towards surviving Ishvalans. The leader who initiated the genocide is somehow still seated in power and continues to uphold a destructive Lebensraum policy, but it helps when you're a superpowered Artificial Human backed by a truly ancient and sinister Government Conspiracy. This is a somewhat unusual example in that Amestris is mainly inspired by industrial revolution era Britain, and the Ishvalans are based on the Ainu people, but it manages to look like a parallel to Nazi Germany anyway.
He dissolved the parliament of Amestris, so that explains how he's still in power.
King Bradley (King is his first name (and it's a real name, too; just ask King Gillette)) is actually President King Bradley in his position of head of state, and Führer King Bradley in his job as head of the military. As such, he is occasionally called President-Führer King Bradley. Talk about ego.
In the canon of the 2003 anime, it's even revealed that the story is set in a parallel world to our own, during the time frame of World War I, and World War II is in the works.
The Principality of Zeon and its successor movement Neo Zeon from the UC Gundam timeline. The most famous instance is where Prince Gihren Zabi turns a state funeral into a political rally, with the audience shouting "Sieg Zeon!" (Hail Zeon in the dub). Lampshaded when King Degwin Zabi compares his son, Gihren to Hitler and Gihren accepts it as a complement.
On the other side of the war, the Titans in Zeta Gundam also have an SS vibe.
The Sleeves, The Remnant of Neo Zeon, have Nazi-esque designs for their mobile suits: example, the Geara Zulu has a distinctive helmet shape. Their soldiers use "All Hail Neo Zeon!" as a battle cry of sorts.
Breiking Boss and his Androkorps in Shinzo Ningen Casshern are an evil android army that seek to eradicate the human race. Amongst their many Nazi-esque traits are a swasitka-like insignia and a faux(?)-German salute "Yartze Brakkin!"
A Certain Magical Index has Academy City. Its leader, Aleister Crowley, believes that Espers are a Superior Species that deserve to replace and rule over normal humans, and advocates the Espers to butcher normal humans and develop complexes that makes them feel more human and have the rights to lord over others by means of the Daihasei sports festival. In addition, the city lives extremely by Social darwinism, where Level 0's (normal humans) are treated like they don't exist and are just given enough money to survive if they don't have a job whilst Level 3's, 4's and 5's are given multi-million dollar allowances, get massive discounts for anything they purchase, live in gated communities, and ride in buses capable of taking hits from anti-tank rockets. Furthermore, crimes commited against Level 0's by Espers are rarely reported, even covered up by city management, to the point where some Level 4's and all but one of the Level 5's could take out an entire neighborhood, stick the heads of the dead on pikes and management would donothing.
Ryoko's Troops, the Z4 from the Anime adaptation of the Shangri-La light novel wear SS styled uniforms (Black Tunic, Black Pants, Black Jackboots, and Atlas Corporation armband) Not to mention what happens at the end of Ep.8 Operation Lullaby, when Ryoko orders the massacre of the girls at the prison after Kuniko and Tomoka escape
In TOKYO TRIBE 2, the NEO WU-RONZ, after nearly taking over a majority of Tokyo, becomes the "Skunk Empire", named after its leader and former underling of Mera. The outfits of the Skunk Empire members are reminiscent of Nazi uniforms, with the kana "?" in place of the swastika. Even Skunk, who grew a mustache over the course of two episodes, dresses very similarly to Hitler during his reign as the leader of the Skunk Empire.
Averted as the soldiers have little loyalty to Skunk, and more to Mera and Buppa/Bubba (depending on translation) - shown when Skunk orders his soldiers to fight the resisting Tribes who were not destroyed/amalgated into the Skunk Empire after Buppa/Bubba died. They tore their armbands off after receiving that command and moved against Skunk - and all the other Tribes did too. Also they stopped fighting after hearing Buppa/Bubba died
Trinity Blood has the Rosenkruez Orden, who are a group of vampires (and one evil human) who are terrorists bent on bringing about the end of the world. They are led by Aryan Ubermensch Cain Nightroad and most dress in clear black suits that very strongly resemble SS uniforms.
The American Survivalist Labor Committee (ASLC) in American Flagg threatens a fascist American revolution. The Gotterdammercrat party is more overtly Nazi-themed, complete with swastikas and Putting on the Reich uniforms.
"Arctic Nation", from the eponymous edition of the French-Spanish furry comic book Blacksad, consists of rich, influential white animals (as in, with white fur), who wear early Nazi-style trenchcoats, have a flag which substitutes a stylized snowflake for the swastika, and wear armbands, but in their actual workings they're instead the KKK, complete with sheet robes and burning crosses.
The "Red Sword" in the classic Flash Gordon comic strip is a thinly veiled expy of the Third Reich: Flash returns to Earth especially to stop them invading America, then zooms back to Mongo again.
Somewhat like Norsefire below, HYDRA started off as an actual Nazi organisation during World War II which became independent when the actual Nazis, well, lost. When your founders are Nazis it's no stretch that your organisation end up Nazi-like.
In the Fifth Sleeper story, the Red Skull tells Captain America that HYDRA was always a front for "the true force supreme, NAZIISM!" (His words, not mine.) It says a lot for how hated the Nazis are that HYDRA is, by comparison, a Slaveto PR.
In the Archie Sonic The Hedgehog series, Angel Island was occupied for a time by the Dr. Eggman-backed Dingo Regime, whose soldiers not only wore Brown Shirt-esque uniforms, but who imprisoned all captured Echidnas in what were clearly concentration camps.
Bob Heller, one of the presidential candidates in Transmetropolitan, whose rhetoric is equal parts TheStrongShouldDominateTheWeak and Patriotic Fervor. His campaign insignia is a black "H" in a white circle on a field of red, and other characters openly compare him to the Nazis and his campaign events to the Nuremberg rallies. (Just how much of a Crapsack World is Transmetropolitan? Not only is Heller not the most evil candidate in the race, he's not even the most evil candidate in his party.)
The Norsefire Party in V for Vendetta IS the Nazi Party (if it was late 1990's Britain).
The Norsefire Party were closer to a logical (if extreme) extension of right-wing tendencies in late 1980s Britain; they're a decidedly unsubtle expy of the National Front with some level-grinding in competence. That Norsefire are essentially the Nazi Party and still recognisably a heartbeat away from the government of the time is part of what makes V for Vendetta so chilling.
The head honcho Leader Adam Susan, in an introspective moment before the beginning of his slide into true madness, outright confirms to himself he is fascist, both by the historic and the Nazi definition. In his own mental phrasing (and Norsefire doctrine, no doubt), the war "put paid to freedom".
Norsefire are an implicitly neo-Nazi organisation, and so the parallels are conscious decisions by Norsefire itself. Unlike most entries on this page, Norsefire consciously emulate Nazi Germany.
In Grant Morrison's penultimate arc of New X-Men, Planet X,Holocaust survivorMagneto goes more and more mindlessly berserk as the arc wears on, culminating in his beginning to herd all surviving non-mutants in New York into crematoria. One of his servants even points out that he's acting like a Nazi. This caused a bit of fan outcry, and Marvel execs were so horrified that they immediately said that wasn't Magneto. This is hardly the first time Magneto has been compared to the Nazis, nor the first instance of someone pointing it out to him, or even Magneto acknowledging it himself.
A better received example is an alternate future/dream where Magneto wipes out humanity only to have the dead rise from their graves, including zombie Hitler who compliments him on being such an apt pupil. That probably has something to do with this three-page sequence being the only X-Men-related material ever penned by Alan Moore.
Another incident worth noting—just after Magneto took over Genosha, he mused to Xavier that he didn't think a mutant nation was enough; he hoped to find "a more...definitive solution". Xavier suggests the word he was looking for was "final". Cue defensive rant.
Ultimate Magneto, however, is another story. He is a clear mutant supremacist who has attempted genocide many times. Since this is an alternate Magneto, this was far better received.
You might then be interested in Operation Rebirth from X-Men: Evolution. Logan explains the super soldier program used to turn Steve Rogers into Captain America. Xavier's reply? "A master race?" Logan gets the hint and claims it was the good guys behind the project.
It's hardly just Magneto- extremists who hate and fear mutants want them wiped out in a manner similar to ethnic cleansing. There are numerous Elseworld stories (like Days Of Futures Past) in which this has come true and Mutants are enslaved and imprisoned. Magneto's main motivation is to make sure this doesn't happen. By wiping out the humans first.
Hey! Sometimes he just wants to conquer us instead!
In the Magneto solo series, he admits to using techniques he learned firsthand from Nazis in his crusade against anti-mutant bigots.
The Kreelers (anti-mutant lobby) in the 2000 AD strip Strontium Dog, led by Nelson Bunker Kreelman (pictured above). There's even a Kreeler Youth organisation.
Replaced by The New Church in the SD story arc aptly titled The Final Solution.
Another 2000AD comic, Invasion! and its sequel, Savage, feature the Volgans, a far-right Russian regime. Originally intended to be played by the Soviet Union, Editorial Meddling forced the creators to use a generically authoritarian RuritanianExpy so as not to aggravate officials at the Soviet embassy during a period of fragile détente. They were later explicitly revealed to be Russian.
Likewise, the enemy Norts from Rogue Trooper show quite a number of Nazi characteristics.
Marvel in particular has a large number of Nazi-esque parties and hate groups, including the Magistrates of Genosha (pre Magneto takeover), The Right, The Knights of Genetic Purity, the Watchdogs, The Secret Empire, Purity, and others.
Actually, the name Secret Empire may be a reference to the real life Invisible Empire of the Ku Klux Klan.
My Little Metro: The Warden of the New Lunar Republic prison mines is a magical mind-altering expy of Adolf Hitler. His mooks and likely the rest of the Republic fall under this as well.
Protagonist example in My Little Unicorn . Starfleet believe themselves to be in many ways superior to other species in the multiverse, the winged unicorns have actually conquered parts of other realities and they teach in the militaristic force to always follow orders blindly or you will get socially shunned. Not to forget that they excuse murder by dehumanizing resp. deponyizing their enemies.
Worse, the author admitted on multiple accounts that this is intentional. According to certain posts, he might not even know the significance of something like the Holocaust and thinks mass murder is okay.
The 1972 version of Bluebeard with Richard Burton provides an odd example, due in part to its observance of No Swastikas. For all intents and purposes it's set during the Nazi era - the characters have Germanic names, one scene depicts an anti-Jewish pogrom, Hitler and Reinhard Heydrich are even mentioned by name - yet the setting's never explicitly identified as Germany. Which granted, is the least of the movie's problems.
HYDRA from Captain America: The First Avenger are explicitly stated to have started as a Nazi deep science division, but move away from the Reich after the Red Skull plans on bombing Berlin as part of his plan for world conquest. He even states that due to his deformity, he no longer fits with Hitler's perfect Aryan ideal. Despite this, HYDRA still uses a "Hail HYDRA!" cry and salute that seems suspiciously close to the "Heil Hitler!" salute. Note that HYDRA seems to have at least moved away from the racial purity angle of the Nazi regime, as Jasper Sitwell, a brown-skinned Latino man, is seen as a HYDRA agent in Captain America: The Winter Soldier.
Skye: Yes you are! That is exactly what you are! It's in the S.H.I.E.L.D. handbook, chapter 1! The Red Skull, founder of HYDRA, was a big, fat, freaking Nazi!
John Ford's Cheyenne Autumn (1964) features Karl Malden as a German-accented cavalry officer named Wessels who imprisons the Cheyenne in a concentration camp. He even sports a Hitler mustache and claims, when called out for his cruel treatment of the Indians, that he's Just Following Orders.
Contact. There's a certain amount of alarm when the First Contact signal turns out to be a retransmitted television broadcast of Adolf Hitler giving a speech. Kitz even suggests it comes from Scary Dogmatic Aliens who find his views appealing. Cooler heads point out that aliens wouldn't understand the context of the transmission — the speech is Hitler opening the 1936 Olympics, which would have been the first strong TV signal sent into space. Sending it back is simply their way of showing the message was received.
The Crimson Rivers has two generations of low-profile workers creating a Eugenics program in their remote university town in France and actually have some success until they get killed by the real Big Bad, who happens to be a product of said program.
The German film Das Experiment is a fictionalized dramatization of the Stanford Prison Experiment, which emphasizes the Nazi-like aspects of the guards' behavior. In case the point isn't obvious enough, their leader actually resembles a blond Hitler.
At one point, one of the prisoners even calls him a Nazi.
Das Testament des Doktor Mabuse might be the Trope Codifier. Director Fritz Lang recasts diabolic crime boss Dr. Mabuse as an evil visionary promoting an "Empire of Crime" dedicated to sewing chaos and destruction. Unsurprisingly, Joseph Goebbels saw Mabuse as a Hitler analogue and promptly banned the film.
Of course, Lang's earlier M made a similar analogy, comparing Berlin's underworld to the Nazi Party.
Dr. Strangelove: General Turgidson asks one of the Pentagon secretaries what kind of name "Strangelove" was. The secretary tells him that Strangelove changed his name after he was made a U.S. citizen. Turgidson: "Hmmm...a kraut by any other name..."
The film of Fahrenheit 451 gave the Firemen Nazi-like outfits along with an overall fascistic feel to their system, and a German actor was cast as Montag. This is kind of at odds with the book which makes the dystopian society very "All-American" and rightly or wrongly, Bradbury attributed its start to Political Correctness Gone Mad, with the idea being that people will be much happier "protected" from "upsetting" ideas, something which is far from the Nazi motivation for burning books.
Felidae has Pascal/Claudandus, a cat killing off specific cat breeds that he deems 'unworthy' of existence. It's explained more thoroughly in the book.
The 1940 Charlie Chaplin film The Great Dictator is about a thinly-veiled parody of the Nazi regime, whose leader is named Adenoid Hynkel and whose symbol is the Double Cross. The location is translated from Germany to the fictional country of Tomania; the anti-Semitism is left undisguised.
Harry Potter and the Deathly Hallows shows a snippet of Hermione's torture from the book, except instead of just hearing her disembodied screams, we also see Belatrix doing...something with the dagger in her hand to Hermione's arm. When we see her arm, we can see that Lestrange carved "Mudblood" into the inside of Hermione's forearm, much like how the Nazis tattooed numbers into the forearms of the Jews in concentration camps.
The Lion King gives us the song Be Prepared, in which Scar rallies the Hyenas into setting up a new age in Pride Rock, ruled by Scar and the Hyenas. The Nazi Symbolism is quite clear during a sequence when the Hyenas goose step (the most evilest march ever) by Scar. The scene is directly inspired by Triumph of the Will. This makes the song especially chilling if you watch it in either Hebrew or German.
In Man of Steel, Zod's speeches about saving the world from decline by rooting out inferior bloodlines (and then genociding an inferior species, i.e. humans) are eerily reminiscent of a certain ideology.
In Star Wars, particularly in the ExpandedUniverse, it's definitely possible to see The Empire as Nazilike. It's not just the cut of the officers' uniforms (and Grand Moff Tarkin definitely acts the part of a Nazi official) or the fact that its Faceless Goons are called "stormtroopers". The Empire is also strictly, stridently speciesist, always putting humans before nonhumans, to the point where the nonhumans on the capital planet are restricted to a single sector. And it rose when a charismatic leader talked his way into a high position in a democratic government, created problems, then refused to let go.
Him gaining power by first becoming Chancellor.
Rather ironically, a Rebel ceremony at the end of the original film is clearly modeled on Triumph of the Will.
There is a shot of Trade Federation battle droids marching through an archway on Naboo in The Phantom Menace that is modeled on a famous shot of Nazi troops marching through the Arc de Triomphe in Paris.
The EU even had a flying death camp. The chief scientist onboard was a slightly more honest version of Mengele, who admits he doesn't have scientific reasons, real or imagined-he just tortures and dissects alien beings For the Evulz. (In a comic where the leading man is Boba Fett, you need the occasional villain that makes a merciless bounty hunter look good.)
The One Sith, the Empire's spiritual successors in the comic series Star Wars: Legacy, also emulated several Nazi-like imagery. They even had a genocide policy on Dac that's called the Final Protocol.
In one of the Ewok cartoons and other sources, Palpatine also ordered for a research team to retrieve the Sun Star, an object with implied mystical powers, among other things, referring to how Nazi Germany often sought out occult artifacts to conquer the planet.
Terminator: Skynet and the machines' rule are pretty much the future version of Nazi Germany. In the first film, Kyle Reese has a barcode tattoo that is similar in vein to the barcode tattoos for Nazi concentration camps, and in Salvation, Kyle Reese and several other humans are being placed in what is unmistakably an extermination camp.
Though Nazi Germany took this motive to the extreme, it was by no means the only country to use this kind of practice (at least partially). It would actually be the most...logical method of extermination.
The Three Stooges short You Nazty Spy! (which came out a few months before The Great Dictator) had Moe as Hailstone, leader of Moronica and Larry and Curly standing in for Goebbels and Goering respectively. It also spawned a sequel, I'll Never Heil Again. ("Quit yer Stalin!") With The Three Stooges being Jews in Real Life.
The government in V for Vendetta is very Nazi-like. Also, the leader's name, "Adam Sutler", sounds too similar to "Adolf Hitler" to have been a coincidence, especially when you consider that in the comic the film was based on (see above), his name was "Susan."
In the comic book, he doesn't even pretend to not be fascist.
The film version of Pink Floyd's The Wall features extended sequences of the main character's dreams/hallucinations of himself as the head of a Neo-Nazi group.
William Stryker's genocidal desires peg him as one.
In X-Men: First Class, Sebastian Shaw (who really was a Nazi during the second World War, going under the name "Klaus Schmidt") envisions his mutant-dominated society much as if it were he ruling over 1940s Germany. Ironically, his most scarred victim as a Nazi scientist, Erik "Magneto" Lehnsherr, finds Shaw's mutant supremacy views to be compatible with his own, despite the fact he spends the entire movie chasing the man in an effort to get revenge for killing his mother.
In Animorphs one of the protagonists compares Crayak to a Nazi, given his genocidal plans to wipe out every species but the Howlers. The Ellimist agrees that term is probably accurate "in a moral sense."
The Malwa in the Belisarius Series were there to restore the purity of the human race. Except they were remarkably incompetent about it.
The primary villains of Carson of Venus by Edgar Rice Burroughs are the militaristic, dictatorial "Zani Party," complete with an incompetent ally from a nearby city named Muso.
The Bernice Summerfield novel Down by Lawrence Miles features a member of the Stella Stora Sigma Schutz-Staffel SturmSoldaten (the SSSSSS), "the most ineffective Nazi group since the Outer Hebridean National Party", who is a collection of Nazi stereotypes masquerading as a character (intentionally; his Character Arc is that he realises this). The less ludicrous Fifth Axis appeared later in the same series (now continued as novels and audio plays published by Big Finish). In a case of it all coming full circle, it turned out that the Fifth Axis worked for the Daleks.
German children's book Der überaus starke Willibald. Said Willibald is a mouse who takes over the colony of mice living in the house when things look bad. Then he ostracizes an albino mouse and everyone who opposes his reign. His allies are the fat Hermann-mouse and the smart Josef-mouse who likes to spew slogans like "Flink wie Fledermäuse, hart wie Tirolerbrot, zäh wie Schweineschwarte" (agile like bats, hard as Tyrolean bread, tough as pork rinds - a variation of the Hitler Youth slogan "agile like sighthounds, hard as Krupp steel, tough as leather").
Wolfgang von Uberwald's werewolf "movement" in The Fifth Elephant deserves mention here. Wolf wears a black uniform with a nickel crest of a wolf's head and lightning bolts, uses phrases like "Joy through Strength" and his mother calls dwarfs "subhuman" (Ironically, because they use a different set of idioms than humans do, a dwarf might take that as a compliment).
According to a 1943 OSS profile, "Wulf" was Adolf Hitler's favorite nickname for himself.
The vampires in Carpe Jugulum are also organized racists ("The trolls are stupid, the dwarfs are devious, the pixies are evil and the gnomes stick in your teeth"), but less military about it.
The Dogs' Guild in Men at Arms. Their entry in GURPS Discworld notes that if Big Fido had been human "the Discworld might have been in serious trouble, possibly involving jackboots", and certainly the image of an insane poodle insisting "the proper shape for a dog was a lot bigger" calls to mind a short, dark-haired man going on about Nordic perfection. According to The Discworld Companion, his speeches even included the phrase "the Master race" ... only this was humanity, which caninekind was going to overthrow.
While ideology is lacking, the past Ankh-Morpork shown in Night Watch is a fascist police state along similar lines as that in V for Vendetta. Notably, the Secret Police are called the Cable Street Particulars, which besides being a Shout-Out to the heroic Baker Street Irregulars references the "Battle of Cable Street" between Oswald Mosley's Blackshirts and anti-fascist Londoners. Their leader, Captain Swing, fits the "non-Aryan/perverse Nazi" role, being odd and sickly looking (think Goebbels) yet obsessed with a Eugenic kind of phrenology. (Although phrenology was popular with the sillier sort of criminologists back when Hitler was still painting postcards in Vienna, so it may not be an intended Nazi reference.)
On the other hand the good guys worshiped a messianic warlord, held traditional civilization in contempt, were arrogant about their physical prowess, had an arcane occultist religion which included the use of narcotics, and launched a holy war for the liberation of their race. There's a bit of Black and Grey Morality going on, which is probably deliberate.
The Hittites in The Egyptian are treated as nazi-expies. Which is not really fair. The whole book can be interpreted as an allegory of WWII, but especially the people's reactions to it. The factions aren't supposed to be expies. At most, they are references to World War II.
The Human Crew in Gone is a group dedicated to murdering all the kids with superpowers, who they call a variety of racial slurs including "freaks", "moofs", "mutant freaks", and "chuds" and don't consider to be human, and putting "normals" in control.
The Pure ones in Guardians of Ga'Hoole are owls who believe that Tyto Alba — barn owls — are superior to any other species of owl.
The Death Eaters from Harry Potter believe in the superiority of pure blood, and will kill anyone they feel is inferior to them. Their leader, Voldemort, hates anyone not of pure wizard blood, yet he himself is not pure blood; Adolf Hitler viewed "Aryans," commonly portrayed as blonds with blue eyes as the master race, yet he himself was brown haired with brown eyes, and there are (untrue) rumors about him having Jewish ancestry. J.K. Rowling acknowledged the Death Eaters are supposed to represent the Nazis, though the American-produced film adaptation of Goblet of Fire played with the parallel a bit by having the Death Eaters don costumes resembling black Klansmen's robes.
And that's not even getting into the ''seventh'' book, for most of which the Power Trio are on the run in one of the most blatant parallels of Nazi-occupied Europe ever seen. The Ministry of Magic has become so corrupted from the inside by Les Collaborateurs, that they essentially pass the Nuremberg Laws against Muggle-born wizards, and under the guidance of Umbridge are shown creating pamphlets touting purity of blood whose content and saccharine covers call to mind the publications of Julius Streicher. The various Death Eater minions inside the Ministry are dressed in khaki clothes, with red, white, and black armbands bearing the Dark Mark. The sign of the Deathly Hallows has a history very similar to that of the swastika, as well - originally an innocent symbol, then used by wizard-supremacist Grindelwald, etched on walls by stupid pricks to get attention...
Said Snatchers can also be compared to the Einsatzgruppen that hunted Jews, inter alia, in occupied Europe.
The Garth Nix short story "Hope Chest" features a villain called the Leader who terrifies populations into submission and brings everyone who hears his voice under his thrall.
In the Hostile Takeover (Swann) series, the planet of Waldgrave, where the Dacham brothers grew up, is a planet inhabited by blond blue-eyed people, ruled by an openly fascist government, and devoted to ethnic purity.
In Charles Stross's Iron Sunrise, there's a supposed "master race" called the ReMastered. Stross has said in his blog that his original working title for the book was Space Nazis Must Die!
In It Can't Happen Here, the Windrip regime is lead by a charismatic dictator and characterized by racism, jingoism, vicious suppression of dissent, concentration camps, and foolish wars of conquest. To boot, the Corpo Youth is reminiscent of the Hitler Youth. Especially jarring is the fact that the novel was published in 1935, shortly after the Nazis came into power. Sinclair Lewis' satire proved prescient about the horrors of Nazism, but was unappreciated in its own time for a plot that contemporary critics found improbable, which is to say, they didn't think It Can't Happen Here could happen there.
In Wodehouse's Jeeves and Wooster, Sir Roderick Spode is leader of the Black Shorts, obviously based on Oswald Moseley's Black Shirts. His followers shout 'Heil Spode!' In the TV series, the Black Shorts use the 'flash in the pan' symbol associated with the Black Shirts, and instead of craniometrics or eugenics, they practice a bizarre pseudoscience based on measuring knees.
In Moses, Man of the Mountain the ancient Egyptians are portrayed this way: the nationalist rhetoric of the Pharaoh's speeches, the militaristic foreign policy, the vaguely German-sounding titles, and the all-seeing secret police evoke images of a certain world power of the time.
T. H. White's The Once and Future King has a Hitler analogue in the person of Mordred, who leads the Nazi-like Thrashers. An ant colony, which Merlyn takes King Arthur to visit into using magic, stands in more for fascism generally. The ant society's suppression of individuality is a strong allegory for the totalitarian state. In the postlude The Book of Merlyn, White, through his Author Avatar of Merlyn, stands up in favor of anarchy and what he calls the collectivist philosophies of fascism, communism and capitalism.
In Octavia Butler's Parable of the Talents, the Christian America sect is exactly like the Nazis. They have a Glorious Leader, Jarrett, who persecutes all non-Christians and others who he sees a scapegoats. They place all people they see as "heathens" into concentration camps where they are forced to do hard labor, be converted to Christianity, and raped and beaten. They also often will take the children of the so-called "heathens" in order to raise them as Christians.
In the Redwall book Triss, the land of Riftgard can only be ruled by a member of the Evil Albino family of "Pure Ferrets", who all speak with ridiculous faux-German Funetik Aksents.
The character of BOSS agent Liutnant Verkramp, in Tom Sharpe's novels of apartheid South Africa, Riotous Assembly and Indecent Exposure. Verkramp, the sworn defender of apartheid and the white Boer race, enlists a German psychiatrist, Doktor von Blumentritt, in making precise scientific measurements of black Africans so that he can assess how tainted the Piemburg Police Force is by black blood. Incidentally, sharpe is palynig this as satire and very black comedy.
Sherman Alexie's short story "The Sin Eaters" provides an inversion of this trope: Rounding up minorities in concentration camps? Check. But why? To get bone marrow from them to fight a plague and, rather than wiping them out, forcibly breeding them. The woman the narrator is forced to mate with points out that he's just twelve. And That's Terrible.
The Army of Excellence in Swan Song, who want to destroy everyone who developed disfiguring keloids after nuclear war destroyed America. There's a lot of talk about 'genetic purity', and the leader even wears some vintage SS uniforms.
Warrior Cats. Tigerstar was originally from ThunderClan, but came to power in ShadowClan during their darkest hour; Hitler was from Austria, but came to power in Germany during a low point in its history. Tigerstar merged RiverClan into ShadowClan to form TigerClan; Hitler merged Austria and Sudetenland into Germany to form Greater Germany. Like all good dictators, Tigerstar had his own secret police, consisting of Brokenstar's rogues and Darkstripe. He started imprisoning and mistreating halfClan cats, clearly planning to eventually kill them, because he claimed that they couldn't be trusted, and blamed them all that had ever gone wrong. And finally, up until she realised how evil he was, Sasha was the Eva Braun to Tigerstar's Hitler.
Watership Down's Efrafa warren has aspects of Nazism, Stalinism, and ancient Sparta. It's not really a straight-up allegory, since the Efrafrans aren't shown to be racist and their leader, General Woundwort, actually is the Bad Ass he likes to be seen as, but it is nonetheless a police state obsessed with security, fear of the outside, and physical perfection.
The TV movie and the book The Wave is about starting a youth movement at a high school that is suspiciously close to Nazism, as An Aesop to show how easy it is to get caught up in such a situation. It is based on a true story.
In Robert Jordan's The Wheel of Time, the False Dragon Mazrim Taim uses rank names that the Nazi used. This is more of a Kick the Dog moment to show that Taim is evil and cannot be trusted, rather than trying to portray Taim as Hitler. He also refers to himself as the "M'Hael", or "Leader", and General Bashere is uncertain he's the real Taim because he's shaved his mustache, which may be a subtle Lampshade Hanging.
And there is Dr. Bob Mengele ("no relation") in Wild Cards.
In The Wandering, the assembly of worshipers that Neshi witnesses on the world he winds up on worships a god that demands racial purity at all costs. Judging from the fact that one of their victims was a Jew, it seems to suggest that the last world Neshi ended up on was Earth.
Age of Fire: The Wyrmmaster (the Big Bad of the first book) and his followers are very strong parallels to the Nazis — they view humans as the Master Race, and ascribe to a paranoid delusion that the other hominid races (the elves, dwarves, and blighters) are all part of some grand conspiracy to keep humanity divided and weak. To this end, the Wyrmmaster starts capturing and breeding dragons as Slave Mooks so that his forces can wipe all the other races out.
ABC Afterschool Special: A memorable 1983 installment, titled "The Wave," sees a high school history teacher conduct an unusual experiment to illustrate the chilling reality of the Holocaust and Nazi-ism by dividing his class into three social groups with strict rules stresing that an individual is part of something more important than himself. Things are fun and games at first, but eventually it becomes all too real as the lesson's unintended consequences turns the school into a regimental, regressive state of fascism and one of the groups becoming virtual Nazis.
The Scourge from an episode of Angel are demons whose ideas about racial purity drive them to destroy all creatures that are part demon and part human. A description that fits two of the show's heroes at that point, Angel and Doyle. They even wear Nazi-style trenchcoats. Ironically, unless the Scourge were gigantic or had godlike powers, odds are they have some human taint themselves according to Anya.
Considering all the examples ranging from Real Life to various fictional accounts (like Voldemort) of the so called "pure beings" not being so pure, this is actually a pretty apt inclusion.
The Night Watch in Babylon 5 had a number of Nazi/Brownshirt parallels (notably pro-Earth jingoism and anti-alien xenophobia), with Zack Allan as an example of a sympathetic character who gets swept up in it. He turns against Night Watch when the chips are down. Lampshaded in one episode when a shopkeeper asks members of the Nightwatch if they were "late for their Bund meeting", invoking the Nazi collaborationist German/American Bund.
William Edgars states that, thanks to the anti-telepath virus he developed, "The telepath problem... will finally be over".
The pause suggests that he realizes what he sounds like... but he doesn't back away from his plan.
There's likely some Actor Allusion going on as well since the performer is Jewish and Word of God says Edgars is as well. So no wonder he felt he'd made a faux-paus.
The original Battlestar Galactica has the Eastern Alliance on planet Terra (surprisingly, an aversion to the Planet Terra trope in that it's not Earth), which serves as a fusion of sorts between Nazi Germany and Soviet Union. The uniforms appear to include elements of both, as well as their attitude towards others. They view the Western Coalition (the democratic bloc) as inferiors and are perfectly willing to make peace with them and then attack (Does This Remind You of Anything?). When launching their nukes, the Commandant even tells his subordinates to only put the most "critical and loyal" citizens into bomb shelters, citing the projected casualties from the Western Coalition's nuclear retaliation as "acceptable".
The season 2 Big Bad of Chuck, Fulcrum, used a symbol◊ that greatly resembles the Iron Eagle used by the Nazis. It also uses the Nazi colors of red, white, and black. However, the show offers no insight into Fulcrum's motivations except for a desire to preserve America's "rightful place" in the world.
The Kaleds, ancestors of the Daleks, wear black military uniforms very close to the standard Nazi uniform, complete with faux-Iron Crosses at the neck and give Roman salutes with heel clicking. They're very fond of shouting a lot, violent threats and talk about racial purity. They get painted as Nazis IN SPACE. This is not surprising, since the Daleks themselves were one of the few Nazi-esque villains who were explicitly meant to be substantively Nazi-like, as opposed to just generic Nazi symbolism to make sure the dimwitted know when to boo. It was nicely lampshaded in the 2008 episode "Journey's End" where Martha teleports to Germany to play her part in activating the Osterhagen Key, and Daleks can be heard shouting in German "Exterminieren!" Possibly even more so in "The Dalek Invasion of Earth" (1965) where the Daleks refer to the destruction of the human race as "the Final Solution" and greet each other by jerking their plungers upwards.
Then there's the new British government that shows up in the For Want of a Nail timeline of "Turn Left". By the time the immigrants are being shipped off to "labour camps", WWII survivor Wilf knows exactly where it's going.
When Hiro travels to the future aftermath of the destruction of New York City, the future depicts Nathan Petrelli (actually Sylar, who had killed Nathan far earlier) as president, as well as a hunting down of evolved humans in a very similar manner to Nazi Germany. Mohinder even mentions sarcastically leading evolved humans into Gas Chambers when expressing disgust towards "Nathan's" request to test a serum that would kill evolved humans on Hiro.
Nathan is responsible for starting a similar initiative in Volume 4, where Evolved Humans are rounded up into camps to either suppress their powers or be experimented on... leading to the question, how much of what happened in the Bad Future from Volume 1 was actually Nathan's doing before Sylar stole his identity?
Volume 5 reveals this had also briefly happened once before in secret during the 60's. Ironically, most of the former inmates went onto found The Company, who did pretty much the very same thing.
Highway To Heaven: Jonathan and Mark are sent to a Midwestern small town, where a Jewish man named Everett Solomon (a Nazi war camp survivor, whose parents were killed) is set to speak ... and the organizer of a Neo Nazi-type organization is planning to assassinate him as they make their own hate-mongering speeches. The episode's main driver — racism, as many of Michael Landon's scripts did so eloquently — set up the episode's Aesop: During a planning meeting in the Neo-Nazi group's basement, the leader's son accidentally triggers a machine gun, mortally wounding the leader and two others. The Jewish man (whose son was killed by the goons) has a heart attack and needs a transplant ... and only the Nazi leader's blood type is available. Jonathan visits with the Neo-Nazi leader's wife, urging her to consent to the operation (as her husband's hateful "heart" is not the same as the biological functions of a heart, and that Solomom is a good person), which she does. After Solomom learns that he had received his sworn enemy's heart, he wants to die ... but has a renewed purpose after having a dream where his beloved son and his parents urge him to tell their story to counteract the Nazi group (before it has a chance to re-form).
Minehead Citizen: I don't like the sound of these here boncentration bamps.
The Kromaggs in Sliders are changed to this after the show was moved to Sci Fi Channel. They start wearing Nazi-like uniforms, having breeding programs, and claiming to be the master race. They also perform cruel experiments on humans in order to further their scientific knowledge.
There's one episode in which the sliders visit an alternate U.S. that is turning into a Nazi-like state under a rising demagogue, Gov. Schick (presumably an allusion to Schicklgruber, the surname of Hitler's father). The episode suggests that in this alternate reality there was no Third Reich or Holocaust, making the U.S. unprepared for that type of occurrence in their own country.
There's a moment when Adar, the leader, expresses that he does not wish for Teal'c to return to his world. Initially it seems that he is uncomfortable because Teal'c is Jaffa, but it's soon made apparent the reason he states Teal'c is "not like us" is because he is black.
Colonel Green, the World War III leader recreated in the Star Trek episode "The Savage Curtain" as a symbol of evil, was portrayed as A Nazi by Any Other Name in the Expanded Universe novel Star Trek: Federation, where he's the leader of the "Optimum Movement", and his symbols include geometric shapes (interlocked triangles, rather than the swastika) and black eagles. This portrayal was continued in the Star Trek: Enterprise episodes dealing with Terra Prime, with the hate-group's admiration of Green reflecting the neo-Nazi attitude to Hitler. (The Terra Prime arc was partly written by Judith and Garfield Reeves-Stevens, who also wrote Federation.) A loud thudding sound accompanied Federation making its Big Bad, Adrik Thorsen (presumably intended to be a German name, but it ended up more Scandinavian...still Middle-to-Upper Europe, though), be blonde and blue-eyed.
The whole concept of genetic augmentation is presented to reflect this trope in Star Trek. The first Eugenics Wars in which a bunch of superpowered dictators, (i.e. a "master race") conquered the Earth until they were deposed. Then after you had the Augments who fancied themselves a master race.
In Star Trek: Deep Space Nine, The Cardassians are a clear analogue to a Fascist dictatorship, but as a whole, they're a mix of most of the major Fascist powers. Their actions during the Occupation of Bajor, however, have clear and distinct parallels to the Nazi regime - right down to the forced-labor camps and their treatment of prisoners. This is alluded to throughout the first season and then put clearly on display in its second-to-last episode, "Duet," which deals with the labor camp Gallitep and Kira's reaction to one of its supposed former officers - the parallels to Auschwitz are undeniable.
The parallel is never more clear than during this chilling monologue showing the Cardassian attitude toward Bajorans:
Darhe'el (actually Marritza): Oh, no, no, Major, you can't dismiss me that easily. I did what had to be done. My men understood that, and that's why they loved me. I would order them to go out and kill Bajoran scum, and they'd do it! They'd murder them! They'd come back covered in blood, but they felt clean! Now why did they feel that way, Major? Because they were clean!
The Twilight Zone used this a few times with various different groups and planets, sometimes Nazis, sometimes communists. The best example is "He's Alive", which has Dennis Hopper as a Neo-Nazi figure who's advised by Hitler (He's alive meaning As Long as There Is Evil, Hitler lives on intolerance).
The Visitors of the miniseries (and subsequent series) V were thinly-veiled Nazi stand-ins, complete with extermination camps (meat-processing plants) and an almost-swastika logo. The original concept for the series was to have concerned a fascist regime coming to power in America. In the original miniseries, a Jewish Holocaust survivor acknowledged the parallels.
Pink Floyd's The Wall has Pink become a pseudo-neo nazi leader running his Hammer army from In The Flesh to Waiting For The Worms, after which he has a heel realization. The nazi themes are prevalent throughout, with a symbol that seems inspired by the swastika
The music video for the Pearl Jam song "Do the Evolution" (seen here) has a scene with what are implied to be Nazi troops, but the Swastika is replaced by another symbol. However, the symbol is actually similar to the symbol used by the SS.
In the Greyhawk setting for the Dungeons@Dragons game, one of the main antagonists is the Scarlet Brotherhood, a group of blonde, fair-skinned, blue-eyed humans who preach the inherent superiority of all humans who share their appearance and seek to exterminate the "demi-human" races (such as elves and halflings).
There are a metric crap-ton in Gamma World. There are the Knights Of Genetic Purity who want to genocide all mutants, the Iron Society who want to genocide all non-mutants (obviously they and the Knights don't exactly get along), the Zoopremacists who want to Kill All Humans, and Hoops who are a would-be master race of bunny-men.
In In Nomine, the Archangel of Purity, named Uriel, took his role a bit too far and tried to "purify" the world of a race of beings called Ethereals which included most of the creatures of myth and legend. His "Purge" was largely successful with most Ethereals fleeing Earth for the dream-world; however, God himself eventually intervened and Uriel has not been seen since.
Plus, Uriel was so Hitleriffic, he was able to genocide beings which didn't exist yet!
Paranoia parodies this (among other things) in one module, where the hapless schmucks (Troubleshooters) become hapless smershoviks (Commie troubleshooters), in a Friend Computer-engineered experiment to see what all the fuss with Communism was all about. In this alternate Alpha Complex, the equivalent to the Commies are the "NazCIA", pronounced "Not-CIA", and a mix of the worst (read: cheesiest) Nazi stereotypes melded with the worst (read: cheesiest) CIA stereotypes.
Arguable is how much of this fit in with the Emperor's vision of the future. He fought the Great Crusade to unify humanity under an enlightened order and free it from the oppression of gods or xenos. On the other hand, the anti-mutant angle, xenophobia, and militarism were all his ideas, he didn't show much concern about the well-being of Imperial citizens so long as the Imperium as a whole prospered, and his war on religion was an attempt to starve the Chaos Gods which he officially denied existed. In the end, the Horus Heresy happened, the Emperor was put on life support, and his Imperium devolved into a CommieNazi hellhole where he's worshiped as a god on pain of being burned at the stake.
There's a reason the fandom calls the Imperium "Catholic Space Nazis". Just sayin'.
The Resistible Rise of Arturo Ui has a gang that takes over Chicago, followed by the neighboring town of Cicero. Their resemblance to the Nazi Party is entirely deliberate.
In Knickerbocker Holiday, when Stuyvesant seizes power in New Amsterdam, he proclaims a new "age of strength through joy." His authoritarian rule is compared to "Julius Caesar, dot Italian" and "Attila, dot Aryan," a thinly-veiled allusion to two dictators who held power when the show was written (1938).
The Xylvanians from Battalion Wars are a theme park version of it and WWI Imperial Germany. All of its military are modeled off of Nazi infantry, vehicles, and aircraft and the same feeling of superiority and inferior races exists between Xylvania and other countries.
Die Spinne in Crimson Skies. 1. They're German; 2. They're Fascists; 3. The game series is set in the thirties. It looks like somebody wasn't really trying to hide the obvious here.
The Templars of Kirkwall in Dragon Age II have elements of this, with the most blatant example being Ser Alrik and his "Tranquil Solution" to give magical lobotomies to all mages.
In The Elder Scrolls V: Skyrim, there's the Thalmor, a conclave of elven supremacists, the ruling party of the new Aldmeri Dominion, who initiate an aggressive military policy, and thanks to a treaty drawn up to favor them, they have free reign to hunt down anyone of any dissident religions — namely, those who worship Talos, the Ninth Divine, whom they absolutely refuse to acknowledge as having ascended from his status as a mere mortal man into the ranks of the Aedra. They also believe that elves are superior to all other races, and believe that not just the existence of humanity, but the very possibility of humanity existing is holding them back.
The Elven superiority is implied to be a cover for their overall hatred of mortality. Because of course, that stance would give you less allies.
It's implied that they don't just hunt down, but also execute Talos worshippers outright — there's a Talos shrine near Riverwood where four worshippers were massacred, but managed to take their Thalmor agent murderer with them; and telling a Thalmor Justicar that you worship Talos is one of the surest ways to get him and his buddies to try to kill you.
The wandering Justiciars share a visual and operative resemblance to the Einsatzgruppen, which was a squad consisting of an SS officer and several soldiers. It was their job to patrol around occupied territory and execute "undesirables" with impunity.
Thalmor are also accused of embracing eugenics, euthanizing nine out of every ten children born in Summerset Isle in a bid to maintain the genetic purity of their race, although it's unclear if this is true, an exaggeration, or a misconception born from anti-elf propaganda spread during the early days of the Cyrodiilic empire.
They also annexed the neighbouring land of the more peaceful Bosmer (wood elves) in a way very reminiscent of the Anschluss.
All they're missing now is a leader whose name resembles Adolf Hitler's name (Something like Ayldroosh Hershur), and a little symbol that vaguely resembles the Nazi Swastika.
Also, the Stormcloaks to a lesser extent. A bunch of nationalistic Nords who want to rebuild Skyrim as an independent power, with a "Skyrim for the Nords!" mentality, and they're all led by a charismatic man with a knack for loud, hammyspeeches. Nonetheless, the player can still join them even if s/he is not a Nord.
Although that's only the (far more sympathetic) Fallout 3 version who were actually trying to do good by getting rid of the mutated humans. The original Fallout 2 version is a much better example of this, who truly considered themselves and themselves alone to be the absolute master race, and who intended to kill off the entire population of America (and they tested their method by using it on the residents of the player character's home of Fallout 1 and the inhabitants of the player character's village in Fallout 2).
In Final Fantasy VI, Gestahl wants to breed Kefka and Celes together to form a master race, and Imperial uniforms are Nazi-like. They also do a Nazi salute in Terra's flashback. And yes, they do commit genocide. Repeatedly.
Quite ironically (compared to other examples) Gestahl DOES seem to stand for and be a good example of the order he seeks to implement. That is, until said mad clown kicks him off a flying continent. Germany could only spawn Knight Templars, Blood Knights, and Corrupt Corporate Executives due to its avaricious nature, and the fact its leader was too blinded by his own ego and importance to see the decay directly beneath. There is no one in the upper land-based echelons who resembles Leo. (There was always a large gap between the beliefs and actions of the kriegsmarines and intelligence agencies with the general army, however.)
Taygen in the 5th Geneforge game, who plans to annihilate all nonhumans, even has concentration camps. It shall be left as an exercise to the player whether those who consider his faction the optimal choice constitute a Misaimed Fandom or are a consequence of the series's Grey and Gray Morality.
The Reapers in Mass Effect 3. The Codex details how people are rounded up and placed into death camps where they await eventual extermination depending on whether Reapers see them fit to be melted down as construction material, or mutilated into zombie mooks. It turns out the thing perpetrating this is a glitched AI using faulty reasoning to do what it was programmed - preserve organics at any costs. "Preserve organics" in this case being "kill as many as possible and use their corpses as living ships". The fact that the game ends with you having to surrender to the machinations of the unrepentant perpetrator of these horrific crimes is part of what contributed to the ending controversy.
An even more glaring example is Cerberus, the human supremacist organization introduced in the first game (marginally) but really fleshed out in the second. In the second game, they were portrayed as Well-Intentioned Extremists who merely wanted to look out for humanity rather than crush all other species and place humanity at the top. Then comes the third game. Charismatic, evil leader? Check. Distinctive color scheme and three-headed dog logos everywhere? Check. Racist belief system and a willingness to stamp on the "others" to ascend their idea of a Master Race to absolute power via control of Eldritch Abominations? Triple check.
In Mega Man Zero, because of an energy crisis, the ruling body of Neo Arcadia ends up instituting genocidal and racist policies towards Reploids supposedly for humanity's betterment, and one of the people in charge of Neo Arcadia's policies is Copy X, who himself is an actual Reploid and not even X. This sounds very similar to how Nazi Germany came into effect, as well as the rule of Adolf Hitler.
Who would have thought it? Even Pokémon of all games went for it in Pokémon Platinum, by inserting a cutscene in which Team Galactic leader Cyrus address ranks upon ranks of assembled Team Galactic Grunts: he tells them about creating a world for Team Galactic, free of the "imperfections" of past world along with such lines as "Let there be glory for Team Galactic!" The grunts answers with chants of "Master Cyrus is the greatest!" And to top it off, the character spying on the rally with you goes out of his way to remark how mesmerizing but unthinkable the whole speech was.
Team Flare in Pokémon X and Y are an even straighter example. Their goal is happiness for themselves and themselves only, and their leader seeks to create a more "beautiful" world by killing everyone who isn't a member of Team Flare.
The Movement from Psi-Ops: The Mindgate Conspiracy fits this trope. The meat puppets (basic irreversibly mind-wiped and rewritten soldiers) even have a red armband with the movement symbol on it and jackboots. What really cements it is their belief that psions should rule over the normal humans and the fact that the leader of it all is a general who staged a failed coup who really isn't a psion until he gets the artefacts he needs. For irony points the main character is blonde and blue eyed and none of the bosses are.
Umbrella and Tricell in Resident Evil. The Social Darwinism that Wesker is spouting in 5. Code: Veronica's insanity, up to and including the experimentation on prisoners. In Resident Evil: The Darkside Chronicles, the Nazi vibes of Umbrella are stronger than in Code: Veronica. If you look at the rendering of Steve, he has a barcode tattoo on his left forearm. In the same place that concentration camp prisoners had theirs. Oh, and their leader, Spencer, also intended to create the perfect human by giving children who had superior intelligence genes and molding them into becoming his proxies, and of whom two survived being injected with a virus, one of the survivors, Albert Wesker, also possessing blond hair and, if Darkside Chronicles is to be believed, blue eyes as well, which also significantly enhanced their strength, speed, and endurance to superhuman levels, very similar to the Aryan ideal of the Nazi Regime.
In Starcraft, the United Powers League, forerunner to the United Earth Directorate, definitely invoked images of the Nazis, only more successful. Religion and unsanctioned languages were erased from existence to make way for the "divinity of mankind" while the "impure" members of humanity - 400 million cyborgs, mutants, and criminals - were either executed or used in experiments.
The symbol of the UED, their successor, contains an eagle on a red background. Sound familiar?
The Godwin family preaches the "virtues" of a strong militaristic regime, has soldiers in really snappy gray uniforms with red berets, and tries to make a "Falena for Falenans." They also employ an assassin named Dolph, in case you still haven't gotten it by that point.
Even weirder, parts of the game hint that while Gizel would somewhat prefer to remain in charge, he's deliberately creating a persona as a Hilter-ite villain, so that all the peoples of Falena will unite against him. Gizel comes off as more interested in simply seeing how it'll turn out than in guaranteeing victory for his side. His father is this trope played straight, though not as charismatic.
Similarly, the Kingdom of Highland had always been an aggressive military power since its formation, but it really started to become similar to this afterLuca Blight came into power, leading to thousands of people being needlessly tortured and slaughtered.
There's also Harmonia, an expansionist empire with a strictly segregated society that condones slavery, treats non-human sentients as property rather than people, and seeks in the long term to conquer the world. Oh, and the most privileged caste of citizens, who are the only ones who can currently take any position of real authority? Invariably blond-haired and blue-eyed.
The ruler of Harmonia, Hikusaak, is never seen. But we know that (like Hitler in Nazi Germany) he doesn't fit the blond-haired and blue-eyed standard, because Luc and Sasarai, brown-haired and brown-eyed twins who play major on-screen roles in Suikoden II and Suikoden III, are clones of Hikusaak.
The Desians from Tales of Symphonia are VERY Nazi like. They torment and kill people, in Concentration Camps Human Ranches, and think of themselves as "Superior" (or really, humans are "Inferior Beings!!"), in addition to a slew of other parallels.
The Internet Backdraft over Team Fortress 2's Medic is partly due to this trope. His visual design evokes the aesthetic (in Beta, he even wore his symbol on a team-colored armband), an unreleased trading card claims that he was "raised in Stuttgart, Germany during an era when the Hippocratic oath had been downgraded to an optional Hippocratic suggestion", and his voice clips contain gems such as "Heil us!", "Raus! Raus!" and "I am ze ubermensch!" Fandom is deeply, deeply divided over whether he is an ex-Nazi, a practicing Nazi, or just a very, very fucked up Mad Doctor with a funny accent.
In Tropico 4, the nationalist faction (or at least their leader) is this, if not just a skin head. They dislike any policy that allows people to move to the island, even when the island is facing crippling underpopulation and the closest thing the island has to college is the pub.
The player actually can be this. It is quite possible to set up a nationalistic dictatorship that has teaches militarism in preschool, openly kill any rioter, use your clinics to increase the birth rate, and use your science academy to clone yourself.
The Gassenarl rebels in Valkyria Chronicles II are rebelling against the Gallian government for having been lied to about the Archduchess' Darcsen heritage, and have the "genocidal agenda" and "drab brown uniforms" parts down pat.
Interestingly used in Vandal Hearts. The game starts out with Stalinesque Scary Russian Analogues. Then Stalin himself (Hel Spites) is assassinated by his chief advisor, DOLF and the overall theme switches gears. Two evil empires for the price of one!
The Project (commonly referred to as the Black Lance), from Wing Commander IV: The Price of Freedom is a none too subtle 27th century Nazi analog, complete with a nanomachine-based bioweapon designed to target "undesirable" individuals, a la the Final Solution.
Xenogears had the Solarians, people that lived in the sky and looked down upon the other nations, even going so far as to call anyone who was not Solarian a Lamb.
In Xenosaga Episode 2, there were the mass produced URTVs, all of which had blonde hair, blue eyes, were essentially flawless, and hive-minded. While not necessarily 'evil', their behavior is disturbing and they eventually succumb to madness and commit mass murdering sprees once infected with UDO.
In Minion Comics the leader of the evil organization, Von Gernsbach, wears a Nazi-like red armband, hangs his image on red banners, and installs Hitler's head on a giant gorilla.
In The Order of the Stick, after the revelation of what Minister Malack plans to do with the Empire of Blood when he inherits it in some 30-40 years (to whit: organising for a thousand sentient beings to be sacrificed each day in the name of his deity, Nergal), plus his idle comment of needing to make "some special chamber to do it in" as Tarquin's silly arenas are inefficient, in #875, the forums were immediately filled with posters comparing him to the Nazis and Adolf Hitler in particular. The Giant himself promptly showed up and explained that the issue actually left certain details out; Minister Malack's plans also include creating a ruling caste of vampiric nobles to control the Empire with him, and the chambers, were based on equal parts Soylent Green and factory farming. The professional butchering chambers (the Giant is a vegetarian, see?), are supposed to sacrifice via exsanguination, so that Nergal gets deaths in his honor and the vampires get blood to feed their own hungers.
v2 to v4 of Open Blue's Sirene (back then called Seran) didn't even try to hide its Naziness. Authoritarian Germanic nation led by a Führer, snazzy (albeit red) uniforms everywhere, an intelligence agency that almost directly parallels the SS right down to the Common Ranks, everything except racial superiority beliefs and swastikas. This was toned down in v5.
In the Dutch series Alfred J. Kwak, which features humanized animals, the main character's nemesis is named Dolf. He founds a party called National Crows, he takes power by staging a fascist-style coup, and if he proclaims himself Emperor and dresses in Napoleonic style, he's obviously a satire of Hitler. Oh, and he grows a characteristic mustache. Dolf also tries to enforce "racial purity" while he himself, like Hitler, is hardly up such standard - he's the son of a crow and a blackbird. Yeah, it's a weird show.
Calling Dolf, well, Dolf was considered too much in Germany, in fact, where the character went by the name Kraa instead.
The Fire Nation from Avatar: The Last Airbender . "We are the sons and daughters of fire, the superior element!" a military rally is told. There's genocide in the back-story, attempted genocide in the climax, there's propaganda, revisionist history, indoctrination of the young, and the whole take-over-the-world thing.
While the Fire Nation is definitely paralleling Nazi Germany, its main parallel was Imperial Japan, which had all of the above.
The various Chinese dynasties also were definitively in there if you were looking for them with any regularity.
While we don't know what he did in particular, Chin the Conqueror/the Great is a serious contender for Bonapartism, as seen in the episode Avatar Day.
In the sequel The Legend of Korra, the treatment of non-benders by the Republic City Council (mostly Tarrlok's doing) (Curfews, cutting off electricity, rounding up innocents including children en masse and throwing them in jail) in response to the rising threat of the Equalists is awfully similar to not only the Nazi treatment of Jews, but also the Red Scare and Japanese internment in North America.
The Equalists are also very similar to Nazis, with their desire to "purge impurities..." And there's fact that the leader of this anti-Bender movement in no way fits his own definition of purity.
Ben 10: Alien Force has the High Breed, a race of aliens so obsessed with genetic purity that they seek to exterminate all other races, believing their gene pools to be "inferior".
While it is true that they are obsessed with genetic purity and believe all other races are inferior, the real reason they are trying to exterminate all other races is because they are all sterile due to inbreeding and are such huge dicks they want to take the rest of the universe down with them.
In Clone High, the school's rivals the G.E.S.H. Have a pep rally with similar looking Nazi imagery.
Since Exo Squad is the European Theater of World War IIIN SPACE!, it's no surprise that Phaeton's Neosapien Order has Naziesque qualities in rhetoric and ideology, and somewhat in practice.
There were definitely some very ironic themes one could pick out if you apply enough Fridge Logic to the Neosapien origins and reasons for being.
An episode of the 1980s Fat Albert cartoon had the Junkyard gang confronting a White supremacist group called the Double Cross, their insignia being two X's. This episode subverts things somewhat in the sense that Hitler, the Nazis, Swastikas, and the Holocaust are explicitly and constantly referred to in the course of the episode. Even in the allegorical Brown Hornet segment, Hitler was still mentioned by name.
One episode of the original My Little Pony cartoon featured a group of penguin supremacists that wanted to exterminate all the impure non-antarctic life by creating an endless ice age, and were clear Nazi homages in the process. It was kind of a strange show.
ReBoot is very blatant about this. Megabyte is even called "mein fuhrer" by Herr Doktor and the bi-nomes loyal to him after Megabyte's fall are call neo-virals. The Bad Future where Megabyte took over had all of his subjects tattooed with bar codes.
One episode of Robot Chicken has The Care Bears plotting to exterminate all the impure Care Bear Cousins using blatant Naziesque dialogue in the process. They succeed and are ultimately punished by having Care-alot turned into a dark and terrible hell on Earth: New Jersey.
Cartman's ginger supremacist movement. He refers to Gingers as "the chosen race"; in the climax of the episode, the gingers kidnap every non-ginger with the goal of exterminating them.
The episode "Absolute Power" from Superman: The Animated Series brought Superman to an alien planet that had been conquered by Jax-Ur and Mala, two Kryptonian criminals that had escaped from the Phantom Zone. The parallels with Nazi Germany are present but vague in the beginning, there are stories told of economic depression and social unrest that were corrected when a new discipline-obsessed regime came to power, but it becomes patently hard to miss the symbolism when they start using the Hitlergruß (Nazi Salute).
