It's not fair... nobody to play with... ever again...

Doctor Stanislaus Braun is the overseer of Vault 112, locked by his own choice in a Vault-Tec prototype simulation in which he appears as a young girl named Betty. Before the Great War, Braun was a brilliant scientist working for Vault-Tec, serving as the head of Future-Tec and the creator of the Garden of Eden Creation Kit


Hailing from the German town of Kronach in Bavaria,[1] Dr. Stanislaus Braun is a talented scientist who developed a long, varied career before the Great War. Braun served as the director of Vault-Tec's Societal Preservation Program,[2] as well as the department head of Future-Tec.[3] Braun had a large role in the Vaults' true purpose as sinister scientific experiments.[4] Braun was also in contact with other Vaults,[5] managing their activation and assignment.[6]

Among his experiments were ones involving the field of advanced life preservation. The United States Army contracted Braun to develop various methods of sustaining human life in case of nuclear war.[Non-canon 1] Braun was eventually credited as the sole developer of the Garden of Eden Creation Kit, described as a "fully self-contained terraforming module capable of creating and sustaining life, even amid a desolate nuclear wasteland."[2] When the Great War broke out, Braun escaped to the safety of Vault 112 and remains there in 2277. He left behind his aging, pre-War body in favor of a new virtual life, voluntarily sealing himself in the Vault's simulation loungers.

In the current simulation world of "Tranquility Lane," Braun has created an ideal, pre-War neighborhood and taken up the identity of a little girl named "Betty." As "Betty," Braun speaks in the perfectly simulated voice of a real little girl but once he is revealed, he tends to alternate between the "Betty" voice and his real voice. Most of the residents of Tranquility Lane are unaware of Betty's nature, though Timmy Neusbaum knows that she is "mean."[7] The only person who is fully aware of Betty's true nature is Old Lady Dithers.[8]

For the past two centuries, Braun has been repeatedly creating and exploring new simulated worlds such as "Toucan Lagoon" and "Slalom Chalet," but often becomes bored and began manipulating the simulations to impose cruelty on the other vault dwellers in the simulation, as an attempt to entertain himself. A failsafe terminal in Tranquility Lane shows that Braun commissioned the "Chinese Invasion Failsafe," a means of permanently killing the inhabitants of Vault 112, but much to his disappointment it will not kill him, which would leave him trapped alone in the simulation.[9]

When James approached Braun for assistance in retrieving the one usable Garden of Eden Creation Kit in the Capital Wasteland, Braun trapped him in a simulator pod, forcing James to become a dog in Tranquility Lane.

Tranquility Lane


Tranquility Lane: Braun (as Betty) is the man pulling the strings when the Lone Wanderer enters the Tranquility Lane lounger. He tasks the Lone Wanderer with all sorts of malicious objectives, intended to physically and psychologically torture the residents.

  • Complying with all of Braun's instructions nets significant bad Karma.
  • Activating the failsafe inside the abandoned house gives good Karma for ending the torment of the residents in Vault 112. A side effect of the failsafe is severing all control Braun had over the simulator, leaving him trapped forever, powerless and alone.
  • Completing all of Betty's tasks except the "kill everyone" task and then activating the failsafe instead will result in neutral Karma. Braun reacts to the failsafe the same way as if none of his tasks were completed.

Other interactions

If the Lone Wanderer tries to harm Betty in Tranquility Lane, even after completing the quest, Betty will say they cannot do that in the simulation, and make them pay by instantly killing the Lone Wanderer in what appears to be a pulse blast.

  • As with all "real" Vault 112 residents (i.e. the player character, their Dad and Braun - most pods, including the inhabitants, are just static scenery) in sitting state, Braun is set to both perma-unconscious (closed eyes) and ghost (the player character can target him, but he receives no damage from any source) state.[10] Because of this, even though he is not essential, Braun cannot be killed at all without using console commands. To actually be able to kill him, one must first open his pod by using the console command PlayGroup Forward 1 on it (b724a), and then set ghost 0 on Braun (bd694). Even then, due to him being unconscious, he cannot be targeted in V.A.T.S. (though he can be damaged normally).
  • If the perma-unconsciousness is removed (e.g. by use of console or scripts), he only has the standard dialogue options and voice of a male NPC.
  • Even if the Lone Wanderer decides to run the failsafe and permanently kill the other residents of the Vault, Braun notes that the Vault-Tec failsafe prevent him from dying.
  • Stanislaus Braun is the only person in the Tranquility Loungers that appears to be sleeping, as all the others are permanently awake.
  • Pinkerton stole a memory chip from Braun's terminal, claiming that it was like "stealing from a little girl."[11]
  • The Lone Wanderer can reference Braun as Betty during Operation: Anchorage before getting in the simulation pod by saying "Great, more psychotic little girls" to Protector McGraw.
  • Braun's research is mentioned in the chief scientist's terminal in Vault 75.[12]
  • Braun was familiar with the Enclave and their role in the Vault-Tec program; the AI of Vault 51, ZAX 1.3c, used this knowledge and impersonated him to have the Enclave send a suit of prototype power armor to the vault.[13]


Stanislaus Braun appears only in Fallout 3. He is mentioned in Fallout 4[12] and its add-on Vault-Tec Workshop,[14] as well as the Fallout 76 update Nuclear Winter.[2][13]

Behind the scenes

In an interview with 1UP.com, Emil Pagliarulo stated that Betty was partially inspired by the Twilight Zone episode "It's a Good Life," in which a small, willful child who was born with godlike powers is able to isolate the entire small Ohio town from the rest of the world and keep the population as his own personal playthings, tormenting, torturing and killing them at will.[15]

  15. Emil Pagliarulo, "Fallout 3 Afterthoughts" on 1UP.com: "As for the gameplay there, Betty was inspired partially by the Billy Mumy character in the Twilight Zone episode "It's a Good Life," in which this little kid with godlike powers terrorizes the inhabitants of a town, and "wishes" them into the cornfield when they're bad."

    A preeminent scientist, Doctor Braun headed up many astonishing experiments in his long and varied carrier, but of most interest were his theories on advanced life preservation. It is said that the U.S. Army had contracted Braun to develop various methods of sustaining human life in the case of an atomic war. When war did come, Braun escaped to the safety of Vault 112 and is there to this day, his wizened and wrinkled form given new (virtual) life as a pigtailed little scamp named Betty..."
