The only character in the entire wasteland who talks about centaurs with affection is a nightkin running a radio station on top of a mountain.
Tabitha broadcasts from Black Mountain, interviewing herself through the persona of her broken Mister Handy. When she gets to the subject of centaurs, her exact words are: who could resist those sweet little faces, and that cute way they shuffle around on all those hands they have. Two of those nouns are plural — faces, and hands. She follows it immediately with the correction: but humans must be so caught up with their pleasant features that they forget the most important thing about centaurs. Centaurs eat humans, Rhonda.
Most writing about the centaur in Fallout stops at the summary: a human and a dog melted together in a vat, slow, stupid, spits radioactive saliva, nothing else to say. This article is not going to do that. Because when you line up every version of the centaur that anyone has designed between 1997 and 2026, a very clean pattern comes out of it: every time somebody sits down and designs a centaur seriously, they draw more than one. Every time it actually ships, it gets cut back down to one. And the pattern lands on a sentence the games never say out loud — when you kill a centaur, you do not know how many things you just killed.
The Chryslus Building basement, the densest concentration of centaurs in the Capital Wasteland. They pull themselves across the floor on a bundle of human arms.
The 1997 centaur had two heads, and they bit each other
Start with the fact that gets forgotten most often: the centaur in the first two games and the centaur in every game after them are not the same creature.
The original had two heads. One canine, one humanoid. Each head sits on a thick, elongated neck, and the two necks converge into the main body and the spine at the base of the torso. The body is more upright than later versions, and the mouth holds three long tongues.
The centaur sprite from the first two games. One head is canine, the other humanoid — and in the animation they bite at each other.
The part that matters is that the two heads are not symmetrical in the animation. The canine head struts when the creature walks, and the canine head is the one that attacks. The humanoid head does not participate in attacking. And then the detail that the whole article grows out of: the canine head can be seen biting at the humanoid head — and the humanoid head evades.
Two components of one organism attacking each other, one of which knows how to dodge. Dodging cannot be done to you; it has to be initiated by whatever is being bitten. This is not a fan reading — it is what the sprite animation plays on loop in a 1997 game.
One clarification, since the targeting interface comes up constantly here. Aimed Shot in the first game is not a fixed Vault Boy graphic reused for every creature. There are eight slots, the names are supplied by whatever you are targeting, and unused slots read as question marks. Aim at the Master and the eight read the head, the eyes, the frame, the CPU, and four sets of question marks. On the centaur targeting screenshot the leader line in the upper left lands on the canine head — and on the Master screenshot, the upper-left slot is the one labeled the head.
Whether the humanoid head gets a slot of its own is a point where the two Fallout wikis flatly contradict each other. One says the canine head is the only head labeled as such during an Aimed Shot. The other says the front arms count as arms when targeted, and that this is similar to both heads — both handled as heads. The two sites share a common ancestor, this article will not referee between them, and rests no argument on the point: the evidence here is the animation, not the interface. As a footnote on how unsettled it is, the two sites do not even agree on whether the canine head is on the left or the right.
Hold onto the two heads. They get rediscovered and re-cut repeatedly over the next twenty-nine years.
It is called a centaur because someone mistook its arms for legs
The name comes from a misidentification, and the misidentification is on the record in an official publication.
Fallout 2 Official Strategies & Secrets, page 26, describes it this way: the centaur, so named for its many malformed legs, is tough and strong, but quite stupid, and the recommended tactic is to keep your distance from this creature while you shoot it to death. The entire species name rests on the phrase in that sentence: many malformed legs.
Except they are not legs. In the first two games the rear pair connect to the pelvis and drive movement — those are legs. The front pair assist in walking but connect to the shoulder blades, and when targeted with an Aimed Shot the game classifies them as arms. The middle pair connect to neither, and nobody has ever committed to what they are. By Fallout 3 the ambiguity is resolved in the other direction: the torso has no arms of its own, and the creature drags itself across the ground on a bundle of human arms.
So the creature has no legs. It crawls on human arms. The word centaur does not record what it is; it records the first-glance mistake a wastelander made looking at it — a mass of shuffling hands read as a set of legs. That mistake got printed in the official strategy guide, and then it became the animal’s name for the next two hundred years.
Adamowicz wrote on the draft: the two halves beat on each other when there is no enemy
When Bethesda rebuilt the centaur for Fallout 3, the concept work was done by Adam Adamowicz. The sheet is reproduced in The Art of Fallout 3, and his handwriting is still on it in the margins. The handwriting says more than the painting does.
The sheet shows two heads. He labeled them individually — one is annotated Country, the other Rock n’ roll. He was not drawing two organs. He gave each head a personality.
The line running along the top of the sheet reads: CENTAUR: 2 halves at odds beat on each other when no enemies present.
Adamowicz’s sheet. The line across the top reads CENTAUR: 2 halves at odds beat on each other when no enemies present, and the two heads are labeled Country and Rock n’ roll.
That note and the 1997 animation of a dog head biting a human head are eleven years apart and are the same idea. Adamowicz was not preserving an old asset; he re-derived the creature from scratch and independently reached the same answer — there is more than one thing in there, and they do not get along.
The same sheet carries other annotations — a hanging jaw segment, a twitching spine and sacrum, and at the bottom a structure he labeled CALCIFIED BASE. Most of those survived contact with production. The shipped Fallout 3 centaur does have a mouth full of three writhing tentacles, does have bone sprouting out through the skin, does drag itself forward on a mass of arms.
The two heads are the one thing that did not survive. The shipped Fallout 3 centaur has one head.
Four redesigns compared. Only the 1997 version put the number on the concept sheet into the game unchanged.
The 2015 art book gave it three faces, and Fallout 4 shipped none of them
The material for this section is The Art of Fallout 4. Deep in the creature chapter there is a full-page painting titled CENTAUR. The facing page is SWAN.
The thing in the painting has three faces crowded onto one body. Not three heads — three faces growing out of the same sheet of flesh, offset from each other, pointed in different directions. The number of arms coming off it is higher than the Fallout 3 version.
The Art of Fallout 4, page 200. This painting went to print. The corresponding in-game content is zero.
The weight of that painting only registers against the text that opens the same chapter. Bethesda’s creature team writes there about redesigning creatures returning from Fallout 3: the challenge is to update realism and detail while staying faithful to the original conception, so the things still feel familiar. Then the sentence that matters — there are a handful of cases where they wanted to push a design somewhat away from the original, and when they do, there is usually a specific reason. It is not something they do casually.
That is a first-hand developer statement, and it is a statement of self-restraint: changes are never arbitrary.
Then the other half of the fact: there are no centaurs in Fallout 4. Not one. A full-page design that deliberately put the face count back up to three, printed and published in the official art book, corresponds to exactly zero content in the shipped game.
This needs saying plainly, because the search results are badly polluted: every screenshot you have seen of a centaur in Fallout 4 is from a mod. The Commonwealth bestiary has never contained this species.
The concept art did get one more public appearance. The Magic: The Gathering Fallout crossover set used it as the illustration for card 195, Branching Evolution, painted by Tomas Duchek. The flavor text on the card reads: the Master discovered a new evolutionary path after tossing a human, a dog, and a cat into a vat of Forced Evolutionary Virus. He called his creations centaurs and unleashed them unto the wastes.
A design that never entered a game finally circulated as a playing card. And that flavor text has a problem of its own, which is the next section.
Nobody on the official side has ever managed to count what it is made of
Human plus dog is the popular answer. The first-hand text has never once given an answer that clean. There are three places in the Fallout Bible where the composition comes up, and the wording gets vaguer each time.
Fallout Bible 1, answering a question about mutated animals, says the centaurs are a mash of human, dog, and various other parts — but hey, who knows how that mutation came about; Grey was probably messing around in one of his labs. Read the second half of that again. The person writing the setting document says, inside the setting document, who knows.
Fallout Bible 8 is the more interesting one. The question arrived with a real premise attached: assuming horses did not survive the Great War, can centaurs be tamed? Surviving communities would presumably want large irradiated animals to haul cargo, given the obvious absence of vehicles and of roads to drive them on. The answer: centaurs would be far too vicious to tame. They are a mish-mash of humans and dogs — at least — and they cannot be very comfortable with how they have been, uh, mashed together.
At least. That is the second time an official document declines to finish counting. And the second half of that answer — that they cannot be very comfortable with how they have been mashed together — is the only place in the entire body of material that speaks to what being a centaur is like from the inside. Not how dangerous it is. How uncomfortable it is.
Fallout Bible 9 is the taxonomic one: FEV explains the more grievous mutations in the wasteland — the Master, the Master’s pets such as the floaters and centaurs, super mutants, Harold — while radiation caused most of the other giant-style mutations, the scorpions, rats and ants, and some of the others, such as ghouls. That line puts the centaur firmly on the FEV side, and just as firmly lists it alongside super mutants rather than inside them.
The FEV vats at Mariposa. Centaurs and super mutants come out of the same place, but the Fallout Bible files the former under the Master’s pets.
Back to the card. Its flavor text says human, dog and cat, three ingredients, stated as fact, with considerably more confidence than the source documents ever had. This article is not going to adjudicate that either: card text is licensed merchandise, the Bible is early developer notes, they disagree, and the disagreement is the fact. What is worth noticing is the direction of travel — the version that added certainty is the later one.
Moira’s terminal asked whether it can talk. The answer was: too many tongues, probably
In Megaton, Moira Brown’s terminal keeps a list called Tracking Current Experiments. One line per question, one line per conclusion. The list as a whole is a joke, but it is in-game text, and every entry maps precisely onto a real design detail.
The centaur entry: can centaurs talk? Conclusion — abundance of tongues suggests so.
The premise is accurate. The centaur really does have three tongues in its mouth, carried all the way from the first game through to Fallout 3, where they are described as tentacles rather than tongues. Moira’s reasoning runs: speech requires a tongue, this thing has three, therefore it can presumably produce triple the speech.
The three tongues carried over from the first game. That detail is the entire basis for Moira’s conclusion that it can talk.
The neighboring entry on the same list is: can mole rats be domesticated? Conclusion — yes, if defanged, declawed and lobotomized. That is the register the list operates in.
Set the joke next to Fallout Bible 8 and it stops being funny. The answer a player can find inside the game is that it has too many tongues, so it probably talks. The answer the developers wrote in their own notes is that it is too vicious to tame and probably deeply uncomfortable being what it is. Both point the same way: there is something in that pile of meat that was not fully killed. The series has never let a centaur speak, and has never once said that it cannot.
Tabitha counts plural too
The Mojave puts the centaur in a stranger position than any of the games before it. At Black Mountain — the self-declared State of Utobitha — centaurs are pets.
Tabitha on the radio: one of the many benefits of living in Utobitha is the ready availability of pet centaurs. Her Rhonda persona answers, ooh, I love the centaurs, they’re just so cute. And then Tabitha delivers the line this article opened with — who could resist those sweet little faces, and that cute way they shuffle around on all those hands they have.
Faces, plural. Hands, plural. The centaur model in that game has one face. She is not describing the asset in front of her; she is describing something closer to the 1997 version. This article will not force an explanation onto that, only record it: the one character in the series who keeps centaurs as pets and looks at them daily uses the plural.
What follows the cute remark is where the broadcast is actually going: but humans must be so caught up with their pleasant features that they forget the most important thing about centaurs. Centaurs eat humans, Rhonda. You see, humans are a lot smaller, and much more tender than you or I, so centaurs naturally see them as food. In the same broadcast she explains the founding choice: weak, greedy humans who would just die anyway, or cute, loveable centaurs, who fight and die for us and ask nothing in return — after much deliberation, I went with the centaurs.
The citizenship rules make it blunter. The disclaimer, read out at speed and under her breath: acceptance into Utobitha open to mutants only; former human servants of the Master conditionally accepted for purposes of centaur feeding duties. Feeding duties has two readings, and the broadcast does not specify which one applies.
In a heavily irradiated crater on the road up the mountain lives the only centaur in the series with a name: Moe. Tabitha calls him out on air — I see Moe. Moe the Centaur? Favorite Centaur Moe. What’s he up to? Moe is an evolved centaur, level 7, 150 hit points, sitting on the corpses of two Brotherhood of Steel paladins. Kill him and he comes back roughly three in-game days later.
Moe, the only centaur in the series with a name. Tabitha calls him her favorite centaur on air.
Put it together: on the wasteland’s books the centaur is simultaneously a pet, a soldier, a thing you feed people to, and a thing that eats people. And in the Den, back in Fallout 2, Mom’s Diner puts it on the menu. In her dialogue file DcMom.msg, player line 411 asks what do you have to eat here, and line 357 — inside a block labeled as a random food item list of eighteen entries — answers: centaur chops, my specialty. The same table offers radscorpion stew, mole rat macaroni and deep-fried floater. So add one more category: it is also food.
The man in the show who insists he is a ghoul is growing a second mouth on his shoulder
This section needs a line drawn before it starts. The show has never said that Thaddeus is turning into a centaur. This article is not going to say it either. What follows is description of the text. The inference is the reader’s.
At the end of season one Thaddeus takes the elixir a snake oil salesman sells him for the price of a fusion core. It repairs his crushed foot, lets him survive a crossbow bolt through the neck and close the wound on the spot, and throws in immunity to radiation. Maximus’ read in the moment is that he might be a ghoul. Thaddeus accepts it and has described himself as a ghoul ever since.
Season one, episode seven. A bolt through the neck fails to kill him. Everything that follows rests on the conclusion drawn in this moment: you might be a ghoul.
By season two, episode seven, that has stopped working. Twice in that episode he seeks out Cooper Howard to talk, and both times he opens with the two of us are both ghouls. The first time Cooper simply does not engage. The second time Thaddeus says the worst part is waiting for his nose to fall off — and then shows Cooper the small mouth that has opened on his collar, and asks whether that is normal.
Cooper looks at the mouth. His face registers surprise. He moves his eyes back up to Thaddeus’ face, says nothing at all, and walks away.
Season two, episode seven. He shows this mouth to a man who has been a ghoul for two hundred years and asks whether it is normal. He gets no answer.
Cooper Howard has been a ghoul for two hundred years. He has seen every single thing that happens to a ghoul. He looked at that mouth and chose not to answer.
Later in the same episode the three of them arrive at the north gate of the strip city, and Cooper is in the middle of assigning Thaddeus to take a sniper rifle up to a rooftop for cover. He does not get to finish. Thaddeus’ right arm falls off. Everyone stops. Thaddeus says he has a medical condition.
The wiki entry for the elixir describes its progression this way: the user initially gains a powerful healing factor and immunity to radiation; in time the body begins to deteriorate and mutate, producing symptoms resembling ghoulification, along with the development of additional mouths growing on the torso, and eventually loss of limbs.
Additional mouths growing on the torso. Eventually, loss of limbs. Those two phrases describe, almost word for word, the anatomy the previous seven sections kept running into: extra mouths, surplus limbs, more than one opening on a single body. Whether the show intends to steer this toward the centaur, no text currently answers, and Thaddeus’ arc has not resolved.
Only one thing is certain. This man keeps introducing himself to everyone as a ghoul while a mouth that is not his opens on his body. In twenty-nine years, this is the first time the series has shown what becoming more than one feels like from the inside, in the first person. The human head on the 1997 centaur dodges the dog head biting at it, but it cannot speak. Thaddeus can speak, and what he says is — is that normal?
Three things people usually get wrong
1. Centaurs are a kind of super mutant. They are not. Fallout Bible 9, listing what FEV is responsible for, puts the Master, the Master’s pets (floaters and centaurs), super mutants and Harold in one series — centaurs are parallel to super mutants, not a subset of them. Shared origin in FEV, different branches. Centaurs are explicitly called pets. Super mutants are not.
2. There are centaurs in Fallout 4. There are not. The species does not exist in the Commonwealth bestiary. The official art book gave it a full page and the shipped game contains zero of them. Every Fallout 4 centaur screenshot in circulation comes from a player mod, and a fair number carry mod-specific tells such as hats and floating health bars. Arguing about canon from mod footage is one of the most common sources of error in this series.
3. The centaur has always had one head. Half true. From Fallout 3 onward, yes. In the first two games there were two — one canine, one humanoid, each on its own neck, and in the animation the canine head bites at the humanoid head while the humanoid head evades. The change happened in 2008 as a modeling decision during the rebuild, not as an in-fiction event. The games have never explained where the second head went.
Common questions
What exactly is a centaur made from? Forced Evolutionary Virus is the cause, and Fallout Bible 9 is unambiguous on that. The ingredient list is where the official answers stop agreeing: Bible 1 says human, dog and various other parts; Bible 8 says humans and dogs, at least; the Magic: The Gathering flavor text says human, dog and cat. It is also worth keeping FEV mutation and radiation mutation apart, since they are two entirely different pathways — the centaur belongs to the first, while a great many other Fallout creatures belong to the second. We broke that distinction down in detail in the full breakdown of ghouls.
Which is more dangerous, a centaur or a deathclaw? Not close. The Fallout 3 centaur is level 5, 100 hit points, damage resistance 0, 27 damage in melee, and its ranged attack is a mouthful of radioactive saliva. It moves slowly, and so does the saliva, which travels on a high arc and is easy to walk out of. Its real threat is accumulated radiation rather than immediate damage. A deathclaw is a different order of thing entirely, with a completely different design role; the numbers are laid out in the full breakdown of deathclaws. In combat the centaur mostly functions as the super mutants’ guard dog — the Fallout 3 loading screen says it outright: super mutants are often accompanied by centaurs, which serve as watchdogs and alert their masters to danger.
Is Thaddeus a centaur, and what is Thaddeus turning into? No text in the show says he is becoming a centaur, and this article is not making that call. What is confirmed is that the documented symptoms of the elixir include additional mouths growing on the torso and eventual loss of limbs, and that season two episode seven shows both. Where he ends up is for later episodes.
Why are there no centaurs in Fallout 4 or Fallout 76? There has never been an in-fiction explanation. It is a question of geography and development priorities — centaurs cluster in California and the Capital Wasteland, the areas the Master’s Unity and its remnants operated in, and neither the Commonwealth nor Appalachia sits on that line. The Fallout 4 art book shows the creature was designed, finished and never implemented. The geographic and chronological context is in the complete Fallout timeline.
How this article is sourced
Tier one, in-work text. This is where the bulk of the article sits: the centaur sprite animation in Fallout and Fallout 2 (canine head attacking, canine head biting the humanoid head, humanoid head evading) and the Aimed Shot interface screenshots; Mom’s Diner dialogue in the Den; the Fallout 3 creature stats, the Chryslus Building and Seward Square encounters, Moira Brown’s experiment list, the loading screen text; the complete Black Mountain Radio broadcast transcripts and Moe’s character data; season one episode seven and season two episode seven of the show.
Tier two, official published material. Fallout 2 Official Strategies & Secrets p.26 (the naming); The Art of Fallout 3, Adam Adamowicz’s centaur concept sheet and its handwritten annotations; The Art of Fallout 4, the creature-chapter opening statement from Bethesda’s creature team and the full-page CENTAUR painting on p.200; Magic: The Gathering Fallout set, card 195, Branching Evolution. In this article that tier carries core argument rather than background — the whole thesis is built on the gap between the design sheets and the shipped product.
Tier three, early developer notes (Fallout Bible, 2002). Bible 1 on composition and Grey’s labs; Bible 8 on whether centaurs can be tamed; Bible 9 on the split between FEV mutation and radiation mutation. Where this tier is used, its own hedging is preserved — phrases like at least and who knows how that mutation came about are quoted as they stand, without being tidied up.
Tier four, reader inference. The following are this article’s own judgments and are claimed as such. Grouping the 1997 two-head animation, Adamowicz’s 2008 two halves at odds annotation and the 2015 art book’s three faces into a single pattern is our connection; no official source has ever put those three things side by side. Reading Tabitha’s plural faces and hands as a remnant of an earlier version is likewise speculation, and the game does not explain the inconsistency. Placing the elixir’s documented symptoms next to centaur anatomy is our observation; the show has not drawn that link, and this article does not draw a conclusion on its behalf.
