Three Dog

Three Dog is the radio host of the Galaxy News Radio station in the Capital Wasteland in 2277, playing music that likely would have been heard on the radio in the early post-WWII years, and doubling as a news anchor.

Background
Born to parents who made their way in the world as members of a traveling theater group, Three Dog grew up listening to rock music, hating the government that he never knew (but surely caused the nuclear holocaust), and fully believing in the rights of free speech and communal law. At some point before he established GNR, he was taking Jet and stumbled across Oasis.

He established GNR in 2272, together with Margaret, a radio technician. Should Three Dog die for any reason, she will replace him as the radio host. Since he began, he's been broadcasting to the Wasteland with his voice, public service announcements, and music. At times he makes jests at Enclave Radio.

He's obsessed with the "Good Fight," interpreted by him as fighting the government and other endeavors he considers noble. Often, this means he supports what the Brotherhood of Steel does.

Daily schedule
He stays in the GNR building throughout the entire game and does nothing but offer aid for the Following in His Footsteps quest and giving you an unnamed side quest that can give you a few items that are level-dependent.

Related quests
You will meet him at the GNR headquarters. If you pass the speech during your dialogue, he will immediately tell you his information on your father.

If you fail the speech check, you will have to repair the satellite that broadcasts the GNR signal to beyond the D.C. area. The satellite went down because a Super Mutant thought it "was funny to shoot the shiny round thing". The player character must recover a new one from the Virgo II Lunar Lander. If you pass a Speech check, Three Dog will give you the key/location of his weapon cache. If not, he will just give you the location of James.

Effects of player actions
He will comment on the progress of the Vault 101 Dweller through Galaxy News Radio (just how exactly he receives information about her/him is never elaborated upon). The tone of his comments will depend on the Lone Wanderer's Karma level and solutions to quests (generally, he cheers you on if you do good, insults you if you do evil, and simply wonders about you if you stay neutral or undertake an unusual quest), and he will often refer to the character title you receive for your specific Level/Karma combination. He also appears in person in the conclusion of the GNR quest, directing the Lone Wanderer to Rivet City.

Behind the scenes

 * His voice is performed by Erik Todd Dellums.
 * The name of the character Three Dog might come from a previous character played by Erik Todd Dellums called "Dog 3". -Source IMDB.com.
 * Three Dog could be based on 1960s radio personality "Wolfman Jack", (formerly Moondog) who used to howl & bark between song selections and often placed on-air prank phone calls to strangers. He is featured prominently in the 1973 George Lucas film American Graffiti.
 * He could also be based on the character "Super Soul" from the 1971 movie Vanishing Point, who wore a headwrap similar to Three Dog's and shares his crazy on-air personality. He even refers to the hero of the movie as "our lone driver," similar to Three Dog's remarks about "the Lone Wanderer."
