No-bark Noonan

 is a wastelander living in the Mojave Wasteland in 2281.

Background
Not much is known about No-bark Noonan's past, however when asked about his nickname he reveals that he suffered from either one or multiple Radscorpion stings that pierced his skull. The event no-doubt made him into the man he is. He wanders the streets of Novac spouting conspiracy theories and other ramblings that sometimes have nuggets of truth hidden in them. His shack is furnished with curious items, like mannequins, empty Nuka-Cola bottles dangling from strings on the ceiling and a Sunset Sarsaparilla vending machine covered in military barricades. Noonan is also extremely paranoid of Communists and has many pro-American posters covering his walls.

They Went That-a-Way
You can ask him if he has seen a man in a checkered uniform (Benny); He will say he saw him running away from aliens.

One for My Baby
Despite his obvious madness and his seemingly random, humorous ramblings about 'chupacabras' (with automatic weapons, no less!), 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.

Come Fly With Me
While No-Bark has no clue what is going on at the REPCONN Facility, he humourously states that he believes the plant is inhabited by "Commie ghosts who don't know they're dead". He speculates that their plan is to hi-jack the nearby rockets, so they can travel to the moon, paint it pink and "draw a huge Lenin face on it".

Quotes
"Them quack doctors can say what they want about all the radscorpion stings that done pierced my skull. I know what I seen."

"I don't trust a man that doesn't have something strange going on about him, cause that means he's hiding it from you. If a man's wearing his pants on his head or says his words backwards from time to time, you know it's all laid out there for you. But if he's friendly to strangers and keeps his home spick-and-span, more often than not it means he's done something even his own ma couldn't forgive."

"Well, says No-bark, we got a chupacabra with an automatic weapon. And that's when they get real quiet, 'cause now they see the predicament we're in."

"Come any closer, and I'm liable to stick you with my stickin' knife. Ol' Sticky is feelin mighty ornery on this day."

"It's ghouls I tell ya. Religious ghouls in rockets looking for a land to call their own. Don't you laugh at me! I know a spell that will make you show your true form, cave rat taught it to me." (On Radio New Vegas after completing Come Fly with Me)

Appearances
appears in Fallout: New Vegas.

Behind the scenes

 * Inside No-bark's shack are multiple empty soda bottles attached to strings that go to the ceiling. This may be a reference to H.P. Lovecraft's "The Terrible Old Man" in which the main character would talk to bottles with the same features.
