ok this is gonna be rambley as all hell but i don't care i have lore thoughts. the top bit of this is gonna be straight copy pasted from discord bc i don't feel like rewording myself but i am gonna add some stuff about name hcs that feature my own killjoy world building hcs
so i think sam is from the city but left young enough that he's been living in the zones most of his life. he's been a part of several different killjoy groups but eventually met adam and ben and decided to split off (him being part of so many groups standing in for how much he's traveled).
adam is also from the city but lived there for longer than sam and is relatively new to the zones. this can lead to him being overly stressed in the zones. yet he's adapted to it really well and is an incredible shot and quick draw.
when adam first left bat city he thankfully met ben, who is a zones native. i think maybe he had a little found family growing up but when he met adam had just left to try and find what he wanted out of the zones. badam spend a few years running around and avoiding dracs before meeting sam.
maybe they do some kinda dj gig? but instead of playing music and reporting on the zones they're kinda like storm chasers, getting up in the action and reporting on it live which is both informative and entertaining. this leads to them getting a lot of heat and them pulling stupid plans to get out of it.
maybe ben and adam did some type of dj work before meeting sam but it never really took off until sam suggested trying something new that none of the others were doing (ben and adam as writers but sam as the YouTube brain making them successful)
as for names i dont have anything set in stone yet however. i hc that killjoys get gifted half of their names by their "family" (whether that's birth or found). i think? i got this from omegalomania's fics in ao3 but it could have also been from a random tumblr post. so to use an example from omegalomania's fic (which is sooo good yall should read them), jet star was called jet by his original group and later chose star for himself (if i remember correctly).
so with all this being said, i think by the time badam meets sam, sam already has his full name. ben when he meets adam has half of his name, part of it gifted to him by his original group. adam, as new to the zones, has no name when he meets ben but gets gifted part of it by ben. i also want adams name to have something to do with being "quick", both as a good shot (having the best shot of the three as the best hand-eye coordination irl), being physically fast (having done cross country irl), and quick-witted.
i also think that sam would probably be the driver of the group as both the boss and a runner. his bad luck would constantly get the three of them in trouble.
however i think that ben would be kinda the strategist? not in making plans before an outing but in the moment to get out of trouble due to his crazy luck. i also want to give him crazy inventions but thats moreso based on vibes and wanting him to fill that niche that anything based in reality.
and... i think? thats all of my thoughts? if anyone wants to add anything id love to hear your thoughts!
