Sergeant Bitter-Root

Sergeant  is an NCR soldier stationed in the Mojave Wasteland in 2281.

Background
Bitter-Root is a sniper with the NCR's 1st Recon at Camp McCarran (though after the quest Three-Card Bounty is complete, he will leave McCarran and move to Camp Forlorn Hope). He is very unfriendly and does not like to talk. His bitterness however comes from his tragic past which he tells to the player.

As a child his parents were members of the Great Khans living in Bitter Springs. His father was a sadistic murderer with an alcohol problem who used to take Bitter-Root out shooting NCR (military personnel and civilians alike) since the age of 3 and physically abused him. His mother was an insipid person whose only quality seemed to be her being, to quote Bitter-Root's father, "a smokin' piece of ass". He loathed his parents and the upbringing he received.

Bitter-Root was "liberated" from this environment during the Bitter Springs Massacre by the NCR troops and Major Dhatri (who was a Captain at the time), who took him in as his son - which is why he sometimes refers to him as his father. He claims he does not remember anything about the massacre but when pressed (this requires a skill check) he admits that after the battle the blood he was covered with wasn't necessarily all spilled by the NCR, and that perhaps he had some scores of his own to settle; implying that he burst out in a fit of aggression against the Khans himself (which may be the reason he was not killed by NCR along with the other children at Bitter Springs).

Bitter-Root's name is part of an old Khan ritual; Upon reaching the age of adulthood all Khan children are severely beaten in a rite of passage in which they choose their own new name. Although too young to go through the ritual himself, he chose the name Bitter-Root and feels that the Bitter Springs Massacre was his ritual, and that the Khans "owe" him his name. His choice is a double entendre, referring both to his bitter roots (i.e., his parents) as well as to the traumatic event that he considered his rite of passage - the Bitter Springs Massacre.
