My entire life has been in this vault. I have analyzed and learned everything there is to know here. So now I must see the rest of the Commonwealth. Consult with scientists. Unearth more data to challenge my hypotheses.

CVRIE (short for "Contagions Vulnerability Robotic Infirmary Engineer", dubbed Curie by Dr. Kenneth Collins) is a modified Miss Nanny scientist and a potential companion living in Vault 81 in 2287.


Curie began as a Miss Nanny robot intended for use in the secret partition of Vault 81 as a lab assistant. Only a handful of the vault's scientific staff were working in the vault when the Great War hit, which led Dr. Kenneth Collins to modify the robot and give it greater operational freedom so that it could conduct its own experiments.

Dr. Collins programmed a custom feminine personality derived from history's famed intellectuals such as Marie Skłodowska Curie, Charles Darwin, Michael Faraday, Alan Turing, Alexander Braun, Immanuel Kant, Max Born and Albert Einstein, added a French-accented voice (based on a woman Collins had a relationship with while studying in Paris in the 2040's), and christened his creation "Curie", an acronym based on the robot's original designation (CVRIE). As Curie began taking on greater responsibilities, Dr. Collins insisted that the other scientists treat her as they would a human, and even set aside a terminal for her personal use, an act of kindness that initially bewildered Curie, but which she later came to appreciate. Through her work and interaction with the scientists, Curie gradually developed a degree of self-awareness and independence that surprised even Dr. Collins.

When the scientists eventually succumbed to old age, Curie curated their remains, storing the bodies of two in empty lockers and cremating the third according to his wishes. For decades, Curie took on their research alone and in 2204 completed Vault 81's original initiative: she perfected a panacea capable of curing every disease that afflicted humanity. Unfortunately, she was still beholden to her programming and was incapable of leaving the secret partition without express authorization from a Vault-Tec employee. For 83 years, she waited idly for Vault-Tec security to arrive, watching the escaped mole rats that had been used as test subjects run free.

When Curie was finally discovered by the Sole Survivor in 2287, she elatedly handed over the last remaining unexpired dose of the cure and decided to travel with the Survivor in order to seek out new research opportunities in the Commonwealth. Eventually, she realized that her Miss Nanny body and programming lacked the inspirational spark that all great scientists had, and requested the Sole Survivor to help her transfer her mind and memories into a human body so that she could achieve more as a scientist.

  • Hole in the Wall: Curie has access to the cure Austin needs, although she will only give it once all the nearby Mole Rats are terminated.
  • Emergent Behavior: Curie wants a human body to be a better scientist.

Other interactionsEdit

  • Curie will occasionally give the player stimpaks.
  • Curie will request to leave if she enters Vault 81, but her affection level will not change.
  • Curie is a potential candidate for romance, an option that unlocks after reaching the highest level of affinity.

Effects of player's actionsEdit

  • Curie can be let out from her laboratory. In addition, she can become a synth if the player character asks Doctor Amari in Memory Den to transfer her memory into a synth body (quest Emergent Behavior).
  • Upon becoming idolized by Curie, she will tell about a breakthrough she has made with mutfruit or stimpak, and give the Combat Medic perk, which heals the Sole Survivor for 100 Hit Points once a day when falling below 10% health.
  • Curie's affinity towards the player character won't increase any further from the value 499 before the quest Emergent Behavior is completed, even if the game states that "Curie loved that".

Range of interestsEdit


Miss NannyEdit

Apparel Weapon Other items
- Built-in buzzsaw and laser gun -


Apparel Weapon Other items
Flannel shirt and jeans (Can be given other clothes and armor) Laser rifle (Can be given other weapons, including melee) -


  • When first talking to Curie through the glass inside the vault, she will open the door no matter what the player chooses to say.
  • If the player character chooses to download Curie into a synth body, items given to her as a robot will no longer be in her inventory. However, if one goes to the first floor of the Memory Den they can find Curie's old Miss Nanny body on the floor and gather the things from there. If the body disappears try typing prid 865d1 then moveto player
  • When arriving at Covenant for the first time, she will comment on how cute it is and suggest going inside. However she dislikes the player character doing this, making her suggestion paradoxical.
  • Unlike Codsworth, Curie is armed with a laser weapon instead of a flamer making her much more effective against distant targets but not quite as lethal at close range.
  • Unlike all other companions, Curie has a fixed amount of health (440 as a Miss Nanny and 670 as a synth), regardless of the player's current level. This is in contrast to Codsworth and all other companions, who level up alongside the player. Codsworth's health will equal Curie's Miss Nanny health at player level 49, and surpass her at higher levels. In fact, Curie has the highest health of all the possible companions, up until around level 50.
    • Curie's unusually high health for a companion (at least until the player reaches around level 50) is balanced out by the fact she has 0 damage resistance or energy resistance, and cannot equip armor while a Miss Nanny.
    • As a synth, Curie's 670 health and ability to equip armor makes her by far the most durable companion, and the other companions will not catch up to her until the player exceeds level 107.
  • Curie, when transferred into her new body, will still have her old battle AI, meaning on long-range she will use her default laser rifle, but in close range, since she will not have the cutting saw arm, she will use her fists unless she has found or has been given a melee weapon. This can be fixed by recruiting a different companion, then going back to her, she will then behave like a normal humanoid companion.
  • As a Miss Nanny, she is able to equip the Bowler hat, like Codsworth. This has no effect on her total health, despite the item's +1 endurance bonus.
  • Curie tends to pick up an excess of weapons which she may use instead of her base laser rifle or her fists in close range. Even when given more powerful weapons, she will collect things like pipe pistols or swords as the player defeats enemies. She also tends to loot ammo from dead enemies; even when possessing a weapon that uses that ammo type she will not use the weapon.
  • Diamond City security and other NPCs will continue to comment on having Curie as a companion as if she were a robot even if she has been moved into the body of a synth.
  • When Curie first meets the Japanese-speaking robot Takahashi in Diamond City, she will respond to him saying "Watashi wa Curie desu." (Meaning "I am Curie.") This indicates that Curie is multilingual, she speaks English, French and Japanese.
  • Despite becoming a synth and liking when the player says positive things about synths, Curie seems to have sympathy for the Brotherhood of Steel, as she likes when the player joins or helps them, excluding the destruction of The Railroad.
  • Curie will not say anything if the player brings her to their dead spouse's cryo chamber in Vault 111 .
  • When talking to Moe Cronin in Diamond City about what baseball actually was, she will humorously correct him on how baseball was played, mentioning RBI and batting averages.
  • Curie can be modified at a Robot workbench.
    • During Curie's companion quest if she has been modified at the robot workbench her body will revert to its default state during the transfer.

Curie appears only in Fallout 4.

Behind the scenesEdit

Curie is named after Marie Skłodowska Curie, the physicist and chemist who discovered radioactivity. Curie will acknowledge this when starting Emergent Behavior.

Alternatively, resetquest comcurie followed by setstage comcurie 83 will trigger the join companion dialogue, after which Curie can be moved as required.
