Defender Rockfowl patrols the highway flyover 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 only NPCs that consistency carry/use a Gatling laser.
Defender Rococo Rockfowl only appears in Fallout 3.
ps3 If killed, he may respawn again every time his corpse disappears.
