Stanislaus Braun

Doctor Stanislaus Braun is the Overseer of Vault 112, locked by his own choice in a virtual reality simulation in which he appears as a little girl named Betty. He is a major character in Fallout 3.

Before the Great War, he was a brilliant German scientist who worked for the Vault-Tec Corporation as the head of Future-Tec. He is most well known for creating the Garden of Eden Creation Kit.

Background
Hailing from Bavarian town of Kronach, Germany, Dr. Stanislaus Braun was the Director for Vault-Tec's Societal Preservation Program, and notes from other Vaults suggest that he was an outside point of contact for Overseers during the Vault Experiment, either as administrative authority or expert scientific adviser. Though early correspondence showed him taking a larger role in activation and assignment of the Vaults, much of his responsibility had lapsed as he become more immersed in, and obsessed with, the sole administration of Vault 112's virtual reality experiment.

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 could leave him trapped alone in the simulation.

In the current simulation world of pre-War Tranquility Lane, Braun has taken up the identity of a little girl named "Betty" in another attempt to entertain himself - in the simulator he can be anything he wishes to be, and he happens to feel like trying out the form of a young girl. 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 a few are vaguely aware she's important and one child says "she's mean." The only person who seems to be aware of Betty's true nature is Old Lady T. Dithers.

When James approached him for assistance in retrieving the one usable G.E.C.K. in the Capital Wasteland, Braun trapped him in a simulator pod.

Personality
Braun is a textbook sociopath: Braun has a tremendous ego, an inflated sense of his own intelligence, and anger problems. He lashes out over perceived sleights, believes that he is always right, and answers even simple questions with lengthy digressions. Braun has an obsession with causing pain and suffering, and will be distressed if he cannot inflict damage on real people.

Quests

 * Tranquility Lane: Braun (aka Betty) is the man pulling the strings when the Lone Wanderer enters the Tranquility Lane lounger. He tasks the Wanderer with all sorts of malicious objectives, the pursuit of which nets a lot of bad karma. Activating the failsafe gives the Lone Wanderer good Karma for ending the torment of the residents in Vault 112. Doing every task of Betty's except the "Kill Everyone" task and activating the failsafe instead will result in neutral karma.

Other interactions

 * If the Lone Wanderer attacks Betty in the simulation, even after completing the quest, Betty will say "You can't do that here, and now you have to pay," upon which the Lone Wanderer is killed instantly.

Appearances
Stanislaus Braun appears in Fallout 3 and is mentioned in the Fallout 4 add-on Vault-Tec Workshop and Fallout 76.

Behind the scenes

 * In Jean-Luc Godard's 1965 film Alphaville, the movie's hero is sent on a mission to kill a Professor Von Braun - the creator of a super-computer in total control of the inhabitants of a dystopian city.
 * In an interview with 1UP, Emil Pagliarulo revealed 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 annihilates the entire human race except for the adults in his small Ohio town, whom he keeps as his own personal playthings, tormenting, torturing, and killing them at will.
