Clanks

Clanks was a reprogrammed protectron accompanying Greg when the pair encountered Russell Dorsey.

Background
Greg, a RobCo Industries technician before the Great War, found Clanks with damaged leg rotors in a shopping center. Using knowledge from his old job, Greg repaired Clanks servos and hot-wired his motherboard so he would sing and dance on command, later gluing a top hat to its head.

Russell met the pair on the road in the former state of Virginia and was impressed with how Greg had modified the programming, but not so much Clanks' singing voice. Greg then showed Russell how he had modified Clanks' internals, and taught Russell how to do the same.

Appearances
Clanks is mentioned only in Fallout 76, introduced in The Legendary Run update.
