General Atomics International is a pre-War company that mass produced robots up until the Great War.


The company is most well known for their Mister Handy, Mister Gutsy, and robobrain robots, as well as for the construction of nuclear power plants and generators. These were used in many vaults and in the American war robot, Liberty Prime.

Mister GutsyEdit

Mister Gutsy is a modified Type-II Mister Handy designed for military use by the U.S. Army. Mister Gutsy comes with a plasma weapon, flamethrower, and significantly better armor than Mister Handy.


Main article: Robobrain

The robobrain was created by GAI as a military robot for the US. It uses a real organic brain as its processor. Military models are capable of using integrated laser weapons, sonic projection rays, and have human-enough manipulator claws to wield submachine guns and rifles.

Miss NannyEdit

Miss Nanny is an alternative to the Mister Handy model, Miss Nanny units seem to typically speak with a French accent. Rather than being seen as individual models, Miss Nanny and Mister Gutsy units seem to both often be considered as simply being variations of the Mister Handy robots by consumers as well as by their creators.

GAI made Vault-Tec Vault power systems, according to a terminal in the Citadel.


General Atomics International is mentioned in the Fallout manual, Fallout 3, Fallout 4 and its add-on Automatron, but the company's products appear in all Fallout games.
