Curie

Curie is a companion in Fallout 4.

Background
A former assistant in various laboratories, Curie, a sentient "Mrs. Handy" robot, ventured into the wasteland to do some independent research. She has a degree in science, medicine, and the French language, but will torch her enemies with her flamethrower in self-defense.

He programmed her to inherit natures of great scientists (like Curies and Einstein) and added french accent to Curie's speech. He also made other scientists treat her like human, he gave Curie her own personal computer and made her into making notes. She did continue working on scientific researches after all members of secret vault of Vault 81 died, but didn't have any progress on it; she blamed it on lack of experience and material.

Other interactions
Curie will accidentally give player character stimpaks. She will make notices of weirdness of wasteland and human nature, sometimes saying obvious comments like synths do.

Effects of player's actions
Curie can be rescued from her labor. In addition, Curie can become a synth if the player character asks a doctor in Memory Den to transfer her memory in one of the synth bodies.

Appearances
Curie appears only in Fallout 4.

Behind the scenes
Curie's name is most likely a reference to Marie Skłodowska-Curie, a physicist and chemist that researched radioactivity.
