Guarding the bridge from Fairfax ruins is heavy-weapons specialist Rockfowl, who deals with regular raider incursions in a rather laid-back but extremely competent manner. His father was a voracious reader and named him after reading the Encyclopedia Atomica (Volume VIII Radiology-Saskatchewan).
Rockfowl claims to have no beef with Elder Lyons himself or with Lyons' branch of the Brotherhood, but simply sees Lyons' actions as a departure from their basic duties and ergo, not his style.
Defender Rockfowl patrols the highway over the entrance to Fort Independence. Because this is very close to the raider-infested Fairfax ruins, Rockfowl may spot one of the raiders inside the ruins, causing him to run inside for a fight. This draws out all the other raiders and initiates a large firefight that the Defender may not survive without the player's assistance.
He is one of the few NPCs that consistently carries/uses a Gatling laser.
He is one of the rare named NPCs in the game that respawn after being killed.
