As the title says who's your favorite NPC? Mine is definitely No-bark. I never laughed so hard in NV (except mabye in the think tank) when I heard him say "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."

Raul, Cass, some of the named NCR rangers, some of the legion higher ups, Boone (on a team level no real bonding), Arcade Gannon, manny and others I can't remember right now.
