Roy Barnes

 is a cut character from Fallout 76.

Background
He used to be a ranger, however after the Great War, he became a glorified groundskeeper for a unspecified park. He created a handmade mine to keep mole rats away from the park, but after he realized the danger inherent of his powerful handmade mine, he set out to disarm them. He was presumed dead. He authored Barnes' journal and the Barnes' last note holotape before his death.

Behind the scenes
Roy Barnes appears to be a reference to Bill Murray's character, Carl Spackler in the 1980 summer comedy Caddyshack. Like Carl, Roy is a groundskeeper who engages in a metaphorical "war" against rodents. As evidenced in Barnes' journal (which is an word-for-word copy of one of Spackler's lines), they share the same hatred of their rodent enemies. As with Spackler, both of their confrontations with "varmints" end with violence and destruction at the hand of handmade explosives.
