An unusual robotic detective, Nick Valentine operates a small agency in Diamond City along with his assistant Ellie Perkins. In addition to possessing the memories of a late pre-War detective, Nick has certain abilities that complement his investigative skills: he is very effective at hacking computers, and adept at both ranged and melee combat. Valentine believes himself to be a prototype between second generation synths and the latest, which might explain why he exhibits sapient intelligence and is not innately hostile towards non-Institute humans. He is generally well respected throughout Diamond City despite his mysterious origins.
