The Black Devil believed that their mission was flawed and being overridden with guilt from the people they killed in the Enclave's name. They stole a suit of X-02 power armor and left for the Commonwealth where they made an outpost underneath the Boston Police rationing site.
While scavenging, they came across a holotape for a local radio station show on a pre-War Hubris Comics communist fighting superhero known as The Black Devil. This inspired them to use the name of the superhero and use radio signals to locate and aid settlers who are in need of help. Eventually, they grew too old to continue as "The Black Devil" and sealed the armor and weapons within the bunker. They left a note behind within the bunker telling anyone who stumbles upon it to deactivate the radio signals as the songs on them bring back old memories.
By 2287, a unit of Enclave remnants were sent to kill the Black Devil and retrieve the X-02 power armor. The Enclave remnants could not locate the rogue soldier but they eventually discovered the location of the X-02 power armor as well as the Black Devil's underground hideout.
