Motor-Runner

Motor-Runner is the leader of the Fiends, located in Vault 3 in 2281.

Background
He is described as being the sanest of the Fiends, being mentally stable enough to control the band of drugged psychotics and organize them into a credible fighting force, and even establishing a base of operations out of Vault 3. Ranger Bryce Anders remarks that Motor-Runner has survived several previous NCR assassination attempts, which prompted Colonel Hsu to give Anders the mission of killing the Fiend leader personally.

He is found in his throne room in the Vault 3 maintenance wing flanked by his two guard dogs, BoneGnash and GnashBone.

Quests

 * Aba Daba Honeymoon: Diane gives the Courier the quest to deliver some drugs to Motor-Runner.
 * Bounty Killer: The Courier is ordered by James Hsu or Bryce Anders to kill Motor-Runner.

Other interactions
The Courier can sell him various drugs (Jet, Psycho, Buffout) for 20 caps (or 22 caps, if the player passes the Barter check) if you pass a Speech check at the entrance of Vault 3 when speaking to the Fiend at the door. 22 caps is more than the player will ever be able to receive from selling drugs valued at 20, with the exception of one instance involving Ricky.

Appearances
Motor-Runner appears only in Fallout: New Vegas.

Bugs
If you have completed Still in the Dark, Motor-Runner will talk in normal fiend dialogue after the initial forced talk, including, "House is dead, wonder if Motor-Runner will let us hit the Strip now."
 * There is a possible fix for this by engaging him in combat, running to the vault entrance, and then holstering your weapon. This will allow you to complete the quest.
