No-bark Noonan

 is a wastelander living in the Mojave Wasteland in 2281.

Background
He is mentally unstable, and has shotgun traps in his house, as well as test dummy pals.

Interactions with the player character
You can ask him if he has seen a man in a checkered uniform (Benny); He will say he saw him running away from wanamingos.

Despite his obvious madness and his seemingly random, humourous ramblings about 'chupacabras', No-Bark actually gives the player useful information about the night of the crime in the quest One for My Baby, saying that he witnessed shady goings-on at the Dino Dee-lite Front Desk.

You can also play caravan with him.

Appearances
appears in Fallout: New Vegas.

Behind the Scenes
He is a reference to Robert Neville in I Am Legend. He has test dummy friends like Robert, and he also tries to imitate voices, which Robert does when he is watching Shrek.
