General Atomics International

General Atomics International was a pre-war company known for their Mr. Handy, Mister Gutsy and Robobrain robots, as well as building nuclear power supplies, such as those used in many Vaults and Liberty Prime.

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

Mr. Gutsy
Mr. Gutsy is a modified Type-II Mr. Handy designed for military use. Mr. Gutsy comes with a plasma weapon, flamethrower, and significantly better armor than Mr. Handy.

Trivia
The name is an obvious reference to corporate giants General Motors and General Electric, and also the defence contractor General Dynamics, being changed due to the fact that (Highly advanced) nuclear technology is the dominant energy provider in the Fallout universe. It could also be a reference to the large megacorporation of the same name found in the novel The Running Man. As a side note, there really is a General Atomics International Services Corporation. They manufacture unmanned aircraft systems (UAS) like the Predator B and are global leaders in fusion research.
