Violet

 is one of the three Fiend bosses from the quest Three-Card Bounty given by Major Dhatri from Camp McCarren. She's a sniper who has a lot of dogs, and is living in a fort made from abandoned campers southwest of South Vegas Ruins West Entrance and directly south about 100 feet from Poseidon Gas Station. Her fort is almost one full grid away directly west of Vault 3 on the World Map.

Background
Violet is accompanied by multiple guard dogs, whom she breeds herself, according to Major Dhatri; the number of dogs depending on level. She is located near the Poseidon Gas Station in the trailer park. Since the quest advises you to travel through the South Vegas Ruins West Entrance, you may encounter Cook-Cook along the way--so be prepared for him. She is apparently a cannibal, and feeds her dogs human flesh as well. One of her dogs, Violetta, also has a brain that you can take from her corpse. Violetta's brain may be installed into the robot dog follower, Rex. Violetta's brain makes Rex very quick, presumably from the over abundance of drugs.

Loot
Violet's fort (unmarked location) has some good loot, namely:
 * Nuka-Cola Quartz
 * Many temp-status magazines
 * Lots of sniper ammo
 * Decent Armor
 * Violetta's Brain
 * One Super Stimpack

Quests

 * Three-Card Bounty: The Courier needs to kill Violet and retrieve her head for a reward in this quest.
