Kai

Fallout: New Vegas character. The courier

Sarcastic and sly dude that prefers to talk his way out of conflict instead of fighting. He's very good at speaking and convincing people but can come across as rude or too straightforward sometimes. An overall loose and relaxed demeanor; it's common for him to seem as if he isn't taking things seriously but he's just become pretty disillusioned with the chaos of the wasteland.

He isn't against stealing something he may need and he can be very vindictive at times. Most of his time is spent scavenging in ruined pre-war buildings and selling his finds. He usually switches between living at Goodsprings and the New Vegas Strip but wanders around a lot and struggles to settle down in one place. He also does a lot of gambling and drinking; he's definitely blown all his money gambling before and would easily do it again. Very prone to addiction

In-game plotwise, he was born in a small town in California and worked for the Mojave Express for a couple years before moving to the mojave. All of the DLC quests are canon for him except Lonesome Road; there's an AU where he goes to Boston (Fallout 4).
