Bray Husky was the boss of the Husky family at Haddock Cove before the arrival of the Sole Survivor in 2287. Together with the rest of the family, they gathered enough scrap wood and metal to build themselves an outpost on the water. From here, they could see anything approaching from a long distance off and make a living off of fishing. Bray directed the other family members in their chores and occassionally took the night watch of the outpost.
Eventually, the dead fish and chum produced by the family attracted mirelurks to the area, resulting in the deaths of all present. Bray was the last surviving family member, and relayed the fates of the other family members before passing himself.
The following is based on unverified behind the scenes information and has not been confirmed by canon sources.
Bray Husky and the rest of his family are references to the WWE stable known as "The Wyatt Family", which consists of Bray Wyatt, Erick Rowan, Luke Harper, and Braun Strowman. The name "Husky" comes from the fact that Bray Wyatt was originally known as "Husky Harris".
