General Atomics International

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

Overview
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 Handy
Mister Handy was produced by General Atomics International as a house-keeping and defensive robot, able to help out around the house and defend itself and possibly others with its buzzsaw and flamethrower. Mister Handy is speech-capable, communicating in a polite English accent.

Mister Gutsy
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.

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 Nanny
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.

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

Appearances
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.

Behind the scenes
The name is a reference to the real-world corporation General Atomic Technologies Corporation, a nuclear physics and defense contractor headquartered in San Diego, California. It is highly similar to the Fallout version, as it is also a frequently government-sanctioned contractor.

The name is also a reference to the popular home appliances company General Electrics. It is closely related to its Fallout version, as both companies specialize in Home appliances.
