We are all biased, are we not? We each care more about our individual communities than other people. We haven't changed, and I'll tell you something else . . . We won't change. Not unless we are of one people. One. One. One. One race. One. One. One. The Unity will allow us to move beyond these petty concerns and deal with the major problems at hand. You want to be a part of that, don't you? Part. Don't.
— The Master

The Master of the Supermutants (? – 2162) was the founder and leader of the Unity, a super mutant organization dedicated to the transhumanist transformation of mankind in post-nuclear New California. By the time he was encountered by the Vault Dweller, the Master was an amalgam of dozens of humans and mutants, integrated into the Cathedral's computer network, speaking in multiple voices and switching between them on the fly.

Alternative names include the Master's birth name, Richard Moreau, the pseudonym adopted after his exile from Vault 8, Richard Grey, and a variety of names used to refer to him by his followers, including Holy Flame, Dark God, Father Hope and others.[1]

The Master is the antagonist of Fallout, encountered at the Cathedral. Destroying him is required to eliminate the mutant threat, although meeting the Master in person is entirely optional.[1]


Richard Moreau was born before the Great War. Little is known about his past, except for the fact that he was one of the lucky few who found shelter in Vault 8 during the Great War. One year after the Vault opened, in 2092, Moreau had the dubious distinction of being one of the first dwellers to be exiled. The accusation was murder, although the circumstances are unknown. Moreau changed his last name to Grey and headed south, towards the coast. He eventually reached the newly-founded Hub, more than four hundred miles to the south, and established himself as a doctor there.[2] He became popular, especially with one of the caravan masters by the name of Harold, who considered him a brilliant doctor and philosopher.[3]

His story could end here, if it wasn't for his ill-fated expedition to Mariposa Military Base, undertaken by himself, Harold, Francine, and Mark in 2102. On June 23, the party was routed by mutants inhabiting the base. Grey was knocked into one of the Vats. His wounded state combined with extreme long-term exposure to the FEV precipitated his evolution into the Master.[4] After he regained consciousness and dragged himself from the Vats, he continued to mutate after the weeks-long immersion.[5][6] The mutation eventually stabilized enough for him to notice his greatly increased mental capacity, capable of resolving the most complex of philosophical questions. He began experimenting on animals infesting the military base by exposing them to the Virus. When he dipped a rat and a dog into the Virus at the same time, the resulting fusion inspired him to begin formulating a philosophy of unification, laying the groundwork for the Unity.[7][8] However, experiments were frustrated by a lack of subjects or understanding of the virus.[9][10]

In December 2102, following a series of directed mutations by injecting doses of the virus into various areas of his mutated body, Grey gained the ability to neurolink with computers, allowing him to access the base's databanks. Aided by the data, he began experiments on humans who strayed into the facilities, without much luck.[11][12] Finally, in January 2103, he finally isolated radiation exposure as the crucial factor affecting transformation success. The first successful super mutant was assimilated by Grey as a fellow mind, creating the Master hive mind. The Unity began in earnest,[13][14] as the Master began to gather test subjects from local human communities. The process was slow, hampered by their scarcity, but over the next thirty years he built up a small force of super mutants, until the Great Winter of 2130 convinced the Master that it is no longer feasible.[15][16]

In 2131, the Master decided to focus on acquiring subjects from caravans that crossed the wasteland in ever increasing numbers. The human settlements were blissfully unaware of the raids, blaming them on monsters, allowing the army to grow tremendously.[17] By 2137, there were enough super mutants to sustain mass production. While the success rate was between 15-20%, with a half going on to join the Master's army, it grew rapidly into a potent military force. The resulting army was named Unity by the Master, becoming the foundation of his vision for humanity and the world.[18] For the next fifteen years, the Unity would expand over New California, striking from the shadows. In 2152, the Master enlisted the aid of Morpheus and his doomsday cultists, creating the Children of the Cathedral to act as the Unity's public face and maintain secrecy.[19]

Just three years later, in 2155, the Unity experienced a breakthrough in its operations. After apprehending a caravan of Vault dwellers from the Los Angeles Vault, the Master transferred his command there and ordered Morpheus' cultists to renovate the building above the Vault, establishing the Cathedral and its Children. The Vault provided a wealth of information to the Master and the Unity, most importantly the locations of other Vaults. Super mutants began searching their suspected locations, gathering prime subjects for super mutant conversion.[20][21] Not all operations were successful: The detachment sent to investigate Bakersfield and Vault 12 wound up engaging the ghouls living among the ruins, with fighting only ceasing when Set brokered a ceasefire, explaining that the ghouls were what remained of Vault 12's dwellers. A garrison was left behind to ensure Set's cooperation and apprehend the occasional human passing through.[22]

The steady expansion of Unity operations and preparation for the attack on New California, spearheaded by the Children of the Cathedral seemed impossible to prevent. However, the Master did not account for the Vault Dweller's interference, who managed to uncover the plan while retrieving a water chip for Vault 13. Spurred into action by Overseer Jacoren, on March 3, 2162, he infiltrated the Cathedral and destroyed it with a nuclear weapon, killing the Master.[23] The Unity retaliated by attacking Necropolis, trying to locate the Vault Dweller, but it was too late.[24] On April 20, less than two months after the death of the Master, the Dweller delivered the killing blow to the Unity by destroying the Mariposa Military Base.[25] Although he disappeared into the wasteland, the Brotherhood of Steel picked up where he left off, driving the super mutants away with minimal loss of life, on both sides of the conflict, establishing itself as a major power in the wasteland, but wisely remaining out of the power structure.[26] Surviving super mutants would attempt to integrate into society or find a new life for themselves, with one of the most notable attempts being Broken Hills, founded by Marcus and Paladin Jacob in 2185, as a place where regular and mutated humans could live side by side.[27] Yet other groups migrated away from New California, north and east, looking for new places to settle.[28]

Power and abilities

The Master began his life as an intelligent, but ordinary human. It wasn't until the expedition into Mariposa that he began to evolve - randomly at first and then by modifying himself with additional doses of the Forced Evolution Virus. The Virus increased his naturally high intelligence many times over, allowing him to understand complex philosophical questions with ease, while slowly warping and twisting his body. Not all the changes were for the worse, however: As his body changed, the Master gained the ability to neurolink with computers and robotics.[29]

Although humans found his appearance repulsive, the evolution provided a countermeasure: It increased the Master's natural charisma and unlocked his latent psionic talent. Already gifted with a silver tongue, Moreau became able to persuade others with impeccable reason, logic, and in-depth understanding of psychology. The few capable of withstanding the strength of his argument would have to concede in the face of the argument of strength: His growing army of super mutants, made possible by resolving the problems of the pre-War FEV.[30]

However, it was the psychic powers that were the most powerful asset the Master had. Long-term exposure to FEV gave him the ability to penetrate the mental defenses of others, preying on their greatest fears and breaking them. His control over them was limited and those members of the Unity or the Children who were granted an audience with him were required to wear psychic nullifiers to pass through the Corridor of Revulsion and the passive psychic field he generated - otherwise they risked physical damage.[31][32]

Finally, the Master was integrated into the Los Angeles Vault ever since the move there from Mariposa. As the biomass and the number of humans and mutants he assimilated increased, the Master integrated himself into the Vault, with tendrils spreading throughout the facilities and burrowing themselves into the underlying technology. The most stunning display was, of course, in the Overseer's chamber, where he grew in and into the command chair. However, the Master neglected to distribute his nervous system in a similar way and the primary brain was still located within the body that assimilated the post and the Vault's main computer.[33]

Interactions with the player character

Interactions overview

This character is involved in quests.


  • Destroy the Mutant leader.: The Master is the mutant leader and the player has to confront him. This can occur in three primary ways:
    • Combat includes facing the Master directly. He has 500 hit points, a Gatling laser, and thick armor. Furthermore, he will spawn a super mutant in the corridor every two turns (four at the lowest combat difficulty), up to a maximum of twelve. Hardened power armor and high damaging weapons are a necessity to withstand the damage output, however, the Master will not attack companions or his Floating Eyes. In fact, the robots are not aggressive towards the player and if splash damage hits them, they will turn on the Master. He is also vulnerable to pulse grenades. Saving and reloading will also cause the spawned mutants to disappear, but still count towards the maximum of twelve.
    • Diplomacy requires the player to have read Vree's autopsy report and have at least 7 Intelligence and good Speech. Then it's a matter of asking him about the plan, pointing out a problem with it and either giving the disk or telling him to ask his female mutants.
    • Stealth involves no confrontation and infiltrating the lowest level via the barracks in the command center. The doors are locked and require a good Lockpick. The player can activate the bomb after killing the guards (they don't take kindly to tampering) by using Science (70% required), Lockpick (70% required; the test was intended to be for Repair, but the game checks for Lockpick) or the bomb key looted from Mariposa.
    • Finally, it is possible to join his cause simply by talking to him and agreeing to his demands or persuasion. Doing so triggers the dipping ending and the raid on Vault 13, but grants no end slides.

Notable quotes

  • "So what shall it be? Do you join the Unity, or do you die here? Join! Die! Join! Die!"
  • "You must be joking."
  • "You think you can destroy me? Destroy! Me?"


The Master appears only in Fallout as a talking head.

Although he only appears in the first game of the series, the Master is mentioned in all Fallout games except for Fallout 4 and Fallout 76.

Behind the scenes

  • The Master has a total of four voices: Three male and one female.
  • His birth name is a nod to The Island of Doctor Moreau, an 1896 science-fiction novel about a scientist attempting to uplift imported animals through surgery and medical experiments.
  • Finally, the Master would have been the villain of the abortive Fallout movie.
  • The Master's phrase "We need one race. Race! Race! One goal. Goal! Goal! One people..." is reference to Adolf Hitler's famous propaganda slogan "Ein Reich, Ein Volk, Ein Fuhrer" translated: "One Empire, One People One Leader"

    "The Master is not a nice person."
    "Once a normal human, long ago, he was mutated by exposure to the FEV virus. Along the way since then, he has somehow hybridized with other human mutants and with computers, turning him into a rather strange and schizoid monster who speaks in multiple voices. As "the Holy Flame" and "Father Hope," he rules the Children of the Cathedral, who figure in his plot to infect all humans with FEV and take over the entire world."
  2. Fallout Bible 0: "2092 Dr. Richard Moreau is exiled from Vault City for murder. The circumstances surrounding the murder are unknown, but he changes his last name to Grey and heads south."

    Harold: "{1100}{hrold300}{Brilliant guy. A doctor and philosopher. Long ago he lead the expedition where I got changed into a mutant.}"
  4. Fallout Bible 0: "2102 June 23 Richard Grey's Expedition [including Harold] finds the Mariposa Military Base and the Expedition is scattered and defeated by mutants at the base. Grey is knocked into one of the vats of FEV by a robotic arm, and Harold is knocked unconscious, only to awaken later out in the wasteland."
  5. Fallout Bible 0: "2102 July Richard Grey, now horribly mutated by the virus, crawls from the Vats covered with FEV and in terrible pain. Barely able to think or perceive his surroundings, he crawls into the Vat control room and begins his audio log. He fades in and out of consciousness, sometimes for days or weeks at a time."
  6. Richard Grey's audio diary: "==0000 - 0004==
    I'm dying. I need to get this down before the pain overwhelms me.
    ==0005 - 0020==
    I can't believe that I was finally able to drag myself out of that vat. The slime did not affect me, but I nearly drowned. I don't know what happened to Harold - he was standing right next to me when the crane knocked me into the vat. He must have been killed or he would have tried to help me. Francine is dead, killed by one of those robots.
    ==0021 - 0027==
    I have no idea how much time has passed. I was able to hack the computer to turn off the robots and record this, but now my mind is slipping away.There is much pain...
    ==0028 - 0043==
    The green slime that I was immersed in is the source of all the mutations we traced to here. My skin is starting to fester and peel. In other areas it is bubbling and is expelling a green mucus-like substance. Some days the pain is almost tolerable.
    ==0044 - 0057==
    I can actually walk a few steps again...It seems inconceivable that I dragged myself all the way up here from the vat room. Strangely, I'm actually feeling stronger, though I'm still in a lot of pain. Everything seems to be getting smaller.
    ==0058 - 0096==
    I think I consumed one of the mutated things scurrying around here today. Before I knew what was happening, some sort of tendril had sprang from my stomach and covered the poor creature. As soon as it had sucked the rodent into my gut I could actually feel its mind. I think. There is the very real possibility that I'm going slowly insane and can no longer differentiate between what is real and what is a hallucination. Maybe I'm still slowly dying in the vat and I've imagined all this. "
  7. Fallout Bible 0: "2102 July-Nov Richard Grey begins to acclimate to his condition, and begins his first tests of animals by exposing them to FEV. These experiments and his growing awareness lay the foundation for his plans for the Unity and the master race. He takes the name, "the Master.""
  8. Richard Grey's audio diary: "==0097 - 0111==
    Things are becoming more clear to me every day. This toxin has actually improved my mind. I feel that I can understand even the most complex philosophical questions simply and directly. It's as if all the layers of artifice have been stripped away. I wonder what would happen if I submerged an animal in the vats for a prolonged period of time? Would it gain awareness?
    ==0112 - 0134==
    The strangest thing is happening to the animals. They actually become smarter and more aware of their surroundings. I dipped a dog and a rat at the same time today, and they were fused together. It's not quite two creatures anymore, but it's more than one. Perhaps this is the future - a coming together of different creatures in some sort of harmonious unity. I no longer consume the different animals I create simply for sustenance - I have become the instrument through which unity will be achieved. I am so much more than a human being now."
  9. Fallout Bible 0: "2102 Nov The first human victim wanders into Mariposa, and Grey consumes him."
  10. Richard Grey's audio diary: "==0135 - 0139==
    It is time to bring others into the glory that is the Unity.
    ==0140 - 0153==
    A lost soul has finally strayed into my home. I was so surprised I consumed him before dipping, a mistake I shall not make again. His mind was so primitive as to be repulsive to my refined cognitive abilities."
  11. Fallout Bible 0: "2102 Dec Grey continues his experiments on wanderers that enter Mariposa... with no success. The creations are flawed (due to the radiation counts in their bodies), making them big but incredibly stupid, and Grey consumes them rather than letting them live."
  12. Richard Grey's audio diary: "==0154 - 0172==
    I've begun to modify myself to be more pleasing to the Unity by injecting small doses of the virus into my body. The slime in the vats is a man-made virus called the Forced Evolutionary Virus. This information was acquired from my newly grown neurolink with the base computer.
    ==0173 - 0198==
    The few wanderers that have found their way here have been a disappointment to me. They can't seem to mutate correctly. The best I've been able to create are some big and dumb mutants. Most can recall nothing from before I initiated them into the wondrous Unity. I only feed on them for fuel, now. Their minds are nothing to me."
  13. Richard Grey's audio diary: "==0199 - 0236==
    Oh glorious creator!! I have succeeded in spreading the complete joy of unification to another soul! Unlike the others, his total radiation count was low. I believe this is the factor we have been overlooking all this time, as it seems the conversion is more successful in the cases with less radiation damage. I have never known such glory as I felt when taking his mind into our own."
  14. Fallout Bible 0: "2103 January The Master discovers the problem with the influence of radiation on his mutations, and he begins to choose his subjects more carefully. The first classic super mutants are born, butt-scratching animations and all. He begins his plans to build an army."
  15. Richard Grey's audio diary: "==0237 - 0281==
    We are beginning to create an army dedicated to unifying the wonderful diversity of life. We have trained them to continue our work here while we search out more populated areas to take into ourselves. We are beginning to feel the limitations of a body that is mobile. We must find a permanent home, with a greater store of knowledge, and a steady supply of bio-mass.
    ==0282 - 0303==
    We have stopped increasing ourself until we can find this new unification center. When we have arrived we will continue to grow and feed until we have brought peace and unity to the entire world."
  16. Fallout Bible 0: "2103-2130 Throughout this period, the Master begins slowly gathering test subjects, willing or unwilling, from local human stock. The Great Winter of 2130 and the scarcity of human subjects make building his army difficult."
  17. Fallout Bible 0: "2131-2135 The Master begins ordering his super mutants to gather human stock from caravans. For many years, the caravan disappearances are blamed on monsters in the desert, and even when the abductions begin to occur on Hub caravans, the deathclaws are blamed. The super mutant army grows."
  18. Fallout Bible 0: "2137 Master's begins to mass-produce super mutants. Only about one in six or one in five attempts are successful, and of these successes, only half seem to last to go on to be part of his growing army, called the Unity."
  19. Fallout Bible 0: "2152 As their influence slowly spreads throughout the wastes, the Master finds humans, doomsday cultists, and rather than dip them in the vats, he demands their obedience as spies - their leader is a man named Morpheus, and he pledges his followers to the Master. Morpheus and his cultists form the future core of the Children of the Cathedral."
  20. Fallout Bible 0: "2155-2156 After capturing a caravan of strange-garbed travelers (vault dwellers), Master learns the location of the Boneyard Vault, the future site of the Cathedral. He conquers the inhabitants and sets up operations there, and the human cultists begin to use the Vault as their powerbase. Within the Vault, the Master learns of other Vaults, and realizing their human occupants are ripe for transformation, begins to send out patrols to Vault locations in search of these other Vaults."

Within the Vault, the Master begins to send out patrols to Vault locations in search of these other Vaults."
  22. Fallout Bible 0: "2157 The Master learns the location of the Bakersfield Vault, Vault 12, and sends a detachment of super mutants there to seize the vault. Many ghouls are snapped like twigs in the attack, and Set finally parleys with the super mutants, telling them that the ghouls are the Vault survivors the super mutants are looking for. The super mutants, angered at failing to find an intact Vault, set up a small garrison at the watershed to watch the inhabitants and insure Set's... cooperation in the war to come."

Last thing I remember before blacking out was something knocking my friend into the stuff."
