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.

Bold text==Background== Violet is accompanied with multiple guard dogs; depends 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.
 * The Bloody Mess Perk also causes havoc with this quest. Try to complete this quest before getting the perk. Also applies to the other fiends.
 * Try to target the legs and kill her that way. Often the legs get blown off and her head is okay to take.
 * Having either rank of the Animal Friend perk, and sniping her to death from a distance, will make the dogs friendly and will not attack you as the retrieve the head. (remember to feed Violetta some buckshot and take the brain if you plan on putting it into Rex)

Loot
Violet's fort (unmarked location) has some good loot, especially
 * Nuka-Cola Quartz
 * Many temp-status magazines
