Let's get a red in here. Some Chinese Cruiser or w/e crashed in the PNW, maybe on worthless Olympic Peninsula. Sort of like the Shi but less technological, just, ya know, Commie Chinese, still in Uniform, not ghouls, in the new 'Fusang Province'. They might be in a little civil war between the 'Radicals' and 'Conservatives' (Dengists/Liberal Socialists? vs Maoists); you might be able to get a companion from either side; both are young and attractive and opinionated of course. But something to really showcase that side of Fallout, which we hear a lot about but never really see.
Same with a actual damn Survivalist, as well. We have The Survivalist. We have paranoid wastelanders. But we never had a 'Survivalist' person in Fallout, and not in a crazy way but a Prepper/common sense sort of way. The middle man between the damn Tribals (which I loathe) but doesn't want to jump right into full blown civilization yet. They have a good thing going where they are, and maybe they might tag along to gain skills or know more about the healing world, but they don't feel that the world is either ready yet for massive civilization or they just don't trust it - if they can maintain a rough 20th century tech level by their near lonesome, why can't anyone else? Wouldn't the world be better off littered with self-sustaining, happy homesteads?
Think of a Ranger archetype. Fantasy RPG ranger, not NCR ranger. A mix of green ideals, anarchic ideals, libertarian ideals, that sort of thing.
Going on with the general PNW vibe (damn I would love if a proper game was set out there), we got a Red Chinese, a Green-Black-Yellow whatever Survivalist, I'm thinking of a Techy sort of person, a tinkerer. Someone who uses all this tech around to make life more comfortable or easy, or wants to make something new. Think of a gnome, a technocrat, a crazy garage scientist, stuff like that. A holdover of the 'Silicon Valley' through Seattle Tech/Start up types. They're all for civilization, technology, progress. Doesn't get along well with groups like the BoS who would try to 'hoard' or 'guide' humanity, but of course they're not some fanatic, they realize the dangers of tech, but think the benefits far outweigh an immediate danger, especially from the ruins of the wastes. May have a streak of commercialism/entrepreneurship as well.
That basically does cover most of the PNW, at least in a fun way.
