Nick Valentine

Nick Valentine is a synth character and potential companion appearing in Fallout 4.

Background
An unusual robotic detective, Nick Valentine operates a small agency inside of Diamond City. Complementing his detective skills, Nick is also experienced at hacking computers, picking locks, along with both ranged and melee combat. Valentine believes himself to be a prototype between first generation Synths and the latest generation of Synths, explaining why he is not hostile towards people. Despite being a Synth, he is generally well respected throughout Diamond City. Although Diamond City holds a hatred towards the institute and their synths, Nick gained their respect by saving the former mayor of Diamond City's daughter, when she ran away with a caravan trader. The caravan trader and his companions were actually kidnappers that took the mayor's daughter hostage. Nick stumbled upon the kidnappers when he was wandering in the Commonwealth wasteland and scared them away by pretending he had a bomb inside of him and started to beep. When the daughter told Nick what happened he returned her to the mayor who gave him a house in Diamond City as a reward to the locals' dismay and objections. Nick began to gain their respect as Diamond City's handyman. His detective skills were noticed when he helped to find a wife who ran away with her lover. People stopped asking Nick to fix things and he became Diamond City's private investigator.
