From fallout 1 who is the Master?

Answer 1

Richard Moreau, AKA The Master, is the final boss of Fallout 1. Born in Vault 8 (later known as Vault City) he was exiled, changing his name to Richard Grey, and joining up with a trader called Harold. While searching for the source of attacks on Harold's caravans by mutant animals, the pair stumbled across the Mariposa Military Base, within which had been created the FEV, Forced Evolutionary Virus.

Inside, an accident caused Richard to fall into an FEV vat, where he remained for a month, mutating into his current form. He developed the ability to absorb other creatures, including people, to increase his intellect. He also perfected the procedure where normal humans are dipped in the vats, to create super mutants.

Along with his allies, the Children of the Cathedral, Grey worked to increase the numbers of his super mutant army. He believed that once everyone had been turned into a super mutant (joining his 'Union'), there would be world piece.

The player character can fight and defeat him in combat, or arm a nuclear warhead on a lower level and destroy him indirectly. Also, he can point out a flaw in Grey's plan, that the FEV sterilises the super mutants (the virus perceives the creation of sex cells to be 'damage' and repairs them), and that the race is doomed. Grey will then allow the player to leave, committiing suicide by arming the bomb himself.
