Nick Valentine is a fictional character in the post-apocalyptic themed Fallout media franchise. Valentine is first introduced as a non-player character in the 2015 role-playing video game Fallout 4, where he plays an important role in its main plotline by lending his assistance to the search for the abducted son of the game's player character, the sole survivor of a cryogenics-focused facility designed to withstand nuclear fallout built by a technology company known as Vault-Tec. Valentine is a type of sophisticated biomechanical android characters in Fallout 4 called "Synths", with cracked synthetic skin torn in spots which expose the metallic structures underneath. Possessing the preserved memories of a human police detective of the same name, Valentine is a private investigator whose speech and mannerisms echo the archetypal detective protagonist from hardboiled fiction. Valentine's other appearances include Fallout: Wasteland Warfare, a miniatures wargame which adapts the Fallout universe. Valentine is voiced by American voice actor Stephen Russell.
