Xenu (/ˈziːnuː/ ZEE-noo), also called Xemu, is a figure in the Church of Scientology's confidential upper-level teachings, where he appears in material known as Operating Thetan level III (OT III). The Xenu narrative forms part of their space opera teachings about ancient extraterrestrial civilizations, catastrophic events in the distant past, and their continuing effects on the spiritual condition of humanity. These materials are treated as trade secrets and are normally disclosed only to Scientologists who have completed extensive preparatory coursework.
According to the OT III account, Xenu was an extraterrestrial ruler of a galactic confederacy who, tens of millions of years ago, transported billions of beings to Earth (then called Teegeeack), placed them around volcanoes, and killed them with hydrogen bombs. The disembodied spirits of the victims, called thetans, are said to have become attached to surviving bodies as "body thetans", contributing to spiritual and psychological difficulties in the present day. Scientology teaches that these entities can be identified and released through specialized procedures at the upper Operating Thetan levels.
The Church of Scientology regards the OT III material as confidential, and instructs members not to reveal or discuss it with those who have not reached the appropriate level. Church officials have often declined to address the Xenu topic in public or have minimized its relevance, while maintaining that the material can only be properly understood in the context of the full Scientology training path. Despite these restrictions, the Xenu narrative has become widely known through court cases, leaks of internal documents, and reporting by journalists and former members, and it has played a significant role in controversies over Scientology's use of copyright and trade-secret law.
Since its disclosure, the Xenu story has attracted sustained attention from scholars, critics, and the media. Academic writers have examined it as a central myth within Scientology, relating it to science-fiction motifs, UFO religions, modern creation narratives, and cosmologies. The story has also been frequently referenced and satirized in television, film, and other media, where it has become one of the most widely recognized elements of Scientology's upper-level teachings.
Summary

The story of Xenu is covered in OT III, part of Scientology's confidential upper levels taught only to advanced members who have undergone many hours of auditing and reached the state of Clear followed by Operating Thetan levels OT I and OT II.[2][3] It is described in more detail in the accompanying confidential "Assists" lecture of October 3, 1968, and is dramatized in Revolt in the Stars, a screen-story in novelistic form written by L. Ron Hubbard in 1977.[2][4]
Hubbard wrote that Xenu was the ruler of a Galactic Confederacy 75 million years ago, which consisted of 26 stars and 76 planets including Earth, which was then known as "Teegeeack".[5][6][7] The planets were overpopulated, containing an average population of 178 billion.[8][9][10] The Galactic Confederacy's civilization was comparable to our own, with aliens "walking around in clothes which looked very remarkably like the clothes they wear this very minute" and using cars, trains and boats looking exactly the same as those "circa 1950, 1960" on Earth.[11]
Xenu was about to be deposed from power, so he devised a plot to eliminate the excess population from his dominions. With the assistance of psychiatrists, he gathered billions[9][5] of his citizens under the pretense of income tax inspections, then paralyzed them and froze them in a mixture of alcohol and glycol to capture their souls. The kidnapped populace was loaded into spacecraft for transport to the site of extermination, the planet of Teegeeack (Earth).[5] The appearance of these spacecraft would later be subconsciously expressed in the design of the Douglas DC-8, the only difference being that "the DC8 had fans, propellers on it and the space plane didn't".[1] When they had reached Teegeeack, the paralyzed citizens were off-loaded, and placed around the bases of volcanoes across the planet.[5][6] Hydrogen bombs were then lowered into the volcanoes and detonated simultaneously,[6] killing all but a few aliens. Hubbard described the scene in his film script, Revolt in the Stars:
Simultaneously, the planted charges erupted. Atomic blasts ballooned from the craters of Loa, Vesuvius, Shasta, Washington, Fujiyama, Etna, and many, many others. Arching higher and higher, up and outwards, towering clouds mushroomed, shot through with flashes of flame, waste and fission. Great winds raced tumultuously across the face of Earth, spreading tales of destruction ...
— L. Ron Hubbard, Revolt in the Stars[2]
The now-disembodied victims' souls, which Hubbard called thetans, were blown into the air by the blast. They were captured by Xenu's forces using an "electronic ribbon" ("which also was a type of standing wave") and sucked into "vacuum zones" around the world. The hundreds of billions[5][12] of captured thetans were taken to a type of cinema, where they were forced to watch a "three-D, super colossal motion picture" for thirty-six days. This implanted what Hubbard termed "various misleading data" (collectively termed the R6 implant) into the memories of the hapless thetans, "which has to do with God, the Devil, space opera, etcetera". This included all world religions; Hubbard specifically attributed Roman Catholicism and the image of the Crucifixion to the influence of Xenu. The two "implant stations" cited by Hubbard were said to have been located on Hawaii and Las Palmas in the Canary Islands.[13]
In addition to implanting new beliefs in the thetans, the images deprived them of their sense of personal identity. When the thetans left the projection areas, they started to cluster together in groups of a few thousand, having lost the ability to differentiate between each other. Each cluster of thetans gathered into one of the few remaining bodies that survived the explosion. These became what are known as body thetans, which are said to be still clinging to and adversely affecting everyone, except Scientologists who have performed the necessary steps to remove them.[6]
A government faction known as the Loyal Officers finally overthrew Xenu and his renegades, and locked him away in "an electronic mountain trap" from which he has not escaped.[14][7][15][16] Although the location of Xenu is sometimes said to be the Pyrenees on Earth, this is actually the location Hubbard gave elsewhere for an ancient "Martian report station".[17][18] Teegeeack was subsequently abandoned by the Galactic Confederacy and remains a pariah "prison planet" to this day, although it has suffered repeatedly from incursions by alien "Invader Forces" since that time.[5][19][20]
In 1988, the cost of learning these secrets from the Church of Scientology was £3,830, or US$6,500.[21][22] This is in addition to the cost of the prior courses which are necessary to be eligible for OT III, which in 2006 was often well over US$100,000 (equivalent to $160,000 in 2025).[14] Belief in Xenu and body thetans is a requirement for a Scientologist to progress further along the Bridge to Total Freedom.[23] Those who do not experience the benefits of the OT III course are expected to pay for it again and repeat the level.[15]
Scientology doctrine
Within Scientology, the Xenu story is referred to as "The Wall of Fire" or "Incident II".[2][6] Hubbard attached tremendous importance to it, saying that it constituted "the secrets of a disaster which resulted in the decay of life as we know it in this sector of the galaxy".[24] The broad outlines of the story—that 75 million years ago a great catastrophe happened in this sector of the galaxy which caused profoundly negative effects for everyone since then—are told to lower-level Scientologists; but the details are kept strictly confidential.
In the OT III document, Hubbard asserts that he entered the Wall of Fire but emerged alive, "probably the only one ever to do so in 75,000,000 years".[13] He first announced his "breakthrough" in Ron's Journal 67 (RJ67), a taped lecture recorded on September 20, 1967, to be sent to all Scientology staff and students.[25][1] According to Hubbard, his research was achieved at the cost of a broken back, knee, and arm. OT III contains a warning that the R6 implant is "calculated to kill (by pneumonia etc.) anyone who attempts to solve it".[21][13] Hubbard claimed that his "tech development"—i.e. his OT materials—had neutralized this threat, creating a safe path through the Wall of Fire.[6][26]
The Church of Scientology forbids individuals from reading the OT III Xenu materials without first having taken the prerequisite courses.[27] Scientologists warn that reading the Xenu story without proper authorization could cause pneumonia.[27][28]
In RJ67, Hubbard alludes to the devastating effect of Xenu's purported genocide:
And it is very true that a great catastrophe occurred on this planet and in the other 75 planets which formed this Confederacy 75 million years ago. It has since that time been a desert, and it has been the lot of just a handful to try to push its technology up to a level where someone might adventure forward, penetrate the catastrophe, and undo it. We're well on our way to making this occur. — L. Ron Hubbard in RJ67 [25]
OT III also deals with "Incident I", set four quadrillion[29] years ago, though scientific consensus places the age of the universe at approximately 13.8 billion years old.[30] In Incident I, the unsuspecting thetan was subjected to a loud snapping noise followed by a flood of luminescence, then saw a chariot followed by a trumpeting cherub. After a loud set of snaps, the thetan was overwhelmed by darkness. It is described that these traumatic memories alone dissociate thetans from their static (natural, godlike) state.[31]
Hubbard uses the existence of body thetans to explain many of the physical and mental ailments of humanity which, he says, prevent people from achieving their highest spiritual levels.[6] OT III tells the Scientologist to locate body thetans and release them from the effects of Incidents I and II.[6] This is accomplished in solo auditing, where the Scientologist holds both cans of an E-meter in one hand and asks questions as an auditor. The Scientologist is directed to find a cluster of body thetans, address it telepathically as a cluster, and take first the cluster, then each individual member, through Incident II, then Incident I if needed.[6] Hubbard warns that this is a painstaking procedure, and that OT levels IV to VII are necessary to continue dealing with one's body thetans.
The Church of Scientology has objected to the Xenu story being used to paint Scientology as science fiction fantasy.[32] Hubbard's statements concerning the R6 implant have been a source of contention. Critics and some Christians state that Hubbard's statements regarding R6 prove that Scientology doctrine is incompatible with Christianity,[33][34] despite the Church's statements to the contrary.[35] In "Assists", Hubbard says:[11]
Everyman is then shown to have been crucified so don't think that it's an accident that this crucifixion, they found out that this applied. Somebody somewhere on this planet, back about 600 BC, found some pieces of R6, and I don't know how they found it, either by watching madmen or something, but since that time they have used it and it became what is known as Christianity. The man on the Cross. There was no Christ. But the man on the cross is shown as Everyman.
Origins of the story
Hubbard wrote OT III in late 1966 and early 1967 in North Africa while on his way to Las Palmas to join the Enchanter, the first vessel of his private Scientology fleet.[24] (OT III says "In December 1967 I knew someone had to take the plunge", but the material was publicized well before this.) He emphasized later that OT III was his own personal discovery.
Critics of Scientology have suggested that other factors may have been at work. In a letter of the time to his wife Mary Sue,[36] Hubbard said that, in order to assist his research, he was drinking alcohol and taking stimulants and depressants ("I'm drinking lots of rum and popping pinks and greys"). His assistant at the time, Virginia Downsborough, said that she had to wean him off the diet of drugs to which he had become accustomed.[37] Russell Miller posits in Bare-faced Messiah that it was important for Hubbard to be found in a debilitated condition, so as to present OT III as "a research accomplishment of immense magnitude".[38]
Elements of the Xenu story appeared in Scientology before OT III. Hubbard's descriptions of extraterrestrial conflicts were put forward as early as 1950 in his book Have You Lived Before This Life?, and were enthusiastically endorsed by Scientologists who documented their past lives on other planets.[5]
Influence of OT III on Scientology

The 1968 and subsequent reprints of Dianetics have had covers depicting an exploding volcano, which is reportedly a reference to OT III.[2][13] In a 1968 lecture, and in instructions to his marketing staff, Hubbard explained that these images would "key in" the submerged memories of Incident II and impel people to buy the books:[11][39]
A special 'Book Mission' was sent out to promote these books, now empowered and made irresistible by the addition of these overwhelming symbols or images. Organization staff were assured that if they simply held up one of the books, revealing its cover, that any bookstore owner would immediately order crateloads of them. A customs officer, seeing any of the book covers in one's luggage, would immediately pass one on through.
— Bent Corydon, L. Ron Hubbard, Messiah or Madman?[40]
Since the 1980s, the volcano has also been depicted in television commercials advertising Dianetics. Scientology's "Sea Org", an elite group within the church that originated with Hubbard's personal staff aboard his fleet of ships, takes many of its symbols from the story of Xenu and OT III. It is explicitly intended to be a revival of the "Loyal Officers" who overthrew Xenu. Its logo, a wreath with 26 leaves, represents the 26 stars of Xenu's Galactic Confederacy.[41] According to an official Scientology dictionary, "the Sea Org symbol, adopted and used as the symbol of a Galactic Confederacy far back in the history of this sector, derives much of its power and authority from that association".[42]
In the Advanced Orgs in Edinburgh and Los Angeles, Scientology staff were at one time ordered to wear all-white uniforms with silver boots, to mimic Xenu's Galactic Patrol as depicted on the cover of Dianetics: The Evolution of a Science. This was reportedly done on the basis of Hubbard's declaration in his Flag Order 652 that mankind would accept regulation from that group which had last betrayed it—hence the imitation of Xenu's henchmen. In Los Angeles, a nightwatch was ordered to watch for returning spaceships.[43]
The Church of Scientology's own organizational structure is said to be based on that of the Galactic Confederacy. The Church's "org board" is "a refined board ... of an old galactic civilization. ... We applied Scientology to it and found out why the civilization eventually failed. They lacked a couple of departments and that was enough to mess it all up. And they only lasted 80 trillion [years]."[44]
Name

The name has been spelled both as Xenu and Xemu.[45] The Class VIII course material includes a three-page text, handwritten by Hubbard, headed "Data", in which the Xenu story is given in detail. Hubbard's indistinct handwriting makes either spelling possible,[45] particularly as the use of the name on the first page of OT III is the only known example of the name in his handwriting. In the "Assists" lecture, Hubbard speaks of "Xenu, ahhh, could be spelled X-E-M-U" and clearly says "Xemu" several times on the recording.[11] The treatment of Revolt in the Stars—which is typewritten—uses Xenu exclusively.[46]
It has been speculated that the name derives from Xemnu, an extraterrestrial comic book villain who first appeared in the story "I Was a Slave of the Living Hulk!" in Journey into Mystery #62 (November 1960). He was created by Stan Lee and Jack Kirby. Xemnu is a giant, hairy intergalactic criminal who escaped a prison planet, traveled to Earth, and hypnotized the entire human population. Upon Xemnu's defeat by electrician Joe Harper, Xemnu is imprisoned in a state of continual electric shock in orbit around the Sun, and humanity is left with no memory of Xemnu's existence.[47][48]
Church of Scientology's position
In its public statements, the Church of Scientology has been reluctant to allow any mention of Xenu. A passing mention by a trial judge in 1997 prompted the Church's lawyers to have the ruling sealed, although this was reversed.[49] In the relatively few instances in which it has acknowledged Xenu, Scientology has stated the story's true meaning can only be understood after years of study. They complain of critics using it to paint the religion as a science-fiction fantasy.[32]
Senior members of the Church of Scientology have several times publicly denied or minimized the importance of the Xenu story,[50][51] but others have affirmed its existence. In 1995, Scientology lawyer Earl Cooley hinted at the importance of Xenu in Scientology doctrine by stating that "thousands of articles are written about Coca-Cola, and they don't print the formula for Coca-Cola".[52] Scientology has many graduated levels through which one can progress. Many who remain at lower levels in the church are unaware of much of the Xenu story which is first revealed on Operating Thetan level three, or "OT III".[13][53] Because the information imparted to members is to be kept secret from others who have not attained that level, the member must publicly deny its existence when asked. OT III recipients must sign an agreement promising never to reveal its contents before they are given the manila envelope containing the Xenu knowledge.[53][54][55] Its knowledge is so dangerous, members are told, that anyone learning this material before they are ready could become afflicted with pneumonia.[27]
Religious Technology Center director Warren McShane testified in a 1995 court case that the Church of Scientology receives a significant amount of its revenue from fixed donations paid by Scientologists to study the OT materials.[56] McShane said that Hubbard's work "may seem weird" to those that have not yet completed the prior levels of coursework in Scientology.[56] McShane said the story had never been secret, although maintaining there were nevertheless trade secrets contained in OT III. McShane discussed the details of the story at some length and specifically attributed the authorship of the story to Hubbard.[57][58]: 104
When John Carmichael, the president of the Church of Scientology of New York, was asked about the Xenu story, he said, as reported in the September 9, 2007, edition of The Daily Telegraph: "That's not what we believe".[59] When asked directly about the Xenu story by Ted Koppel on ABC's Nightline, Scientology leader David Miscavige said that he was taking things Hubbard said out of context.[1] However, in a 2006 interview with Rolling Stone, Mike Rinder, the then-director of the church's Office of Special Affairs, said that "It is not a story, it is an auditing level", when asked about the validity of the Xenu story.[54]
In a BBC Panorama programme that aired on May 14, 2007, senior Scientologist Tommy Davis interrupted when celebrity members were asked about Xenu, saying: "None of us know what you're talking about. It's loony. It's weird."[60] In March 2009, Davis was interviewed by investigative journalist Nathan Baca for KESQ-TV and was again asked about the OT III texts.[61] Davis told Baca "I'm familiar with the material", and called it "the confidential scriptures of the Church".[61] In an interview on ABC News Nightline, October 23, 2009,[62] Davis walked off the set when Martin Bashir asked him about Xenu. He told Bashir, "Martin, I am not going to discuss the disgusting perversions of Scientology beliefs that can be found now commonly on the internet and be put in the position of talking about things, talking about things that are so fundamentally offensive to Scientologists to discuss. ... It is in violation of my religious beliefs to talk about them." When Bashir repeated a question about Xenu, Davis pulled off his microphone and left the set.[62]
In November 2009 the Church of Scientology's representative in New Zealand, Mike Ferris, was asked in a radio interview about Xenu.[63] The radio host asked, "So what you're saying is, Xenu is a part of the religion, but something that you don't want to talk about". Ferris responded, "Sure".[63] Ferris acknowledged that Xenu "is part of the esoterica of Scientology".[64]
Leaking of the story
Despite the Church of Scientology's efforts to keep the story secret, details have been leaked over the years. OT III was first revealed in Robert Kaufman's 1972 book Inside Scientology, in which Kaufman detailed his own experiences of OT III.[65] It was later described in a 1981 Clearwater Sun article,[66] and came to greater public fame in a 1985 court case brought against Scientology by Lawrence Wollersheim. The church failed to have the documents sealed[21] and attempted to keep the case file checked out by a reader at all times, but the story was summarized in the Los Angeles Times[67] and detailed in William Poundstone's Bigger Secrets (1986) from information presented in the Wollersheim case.[68] In 1987, a book by L. Ron Hubbard Jr.,
