I've noticed that band members in fanfics have this kind of archetype thing to them so I'll make a list
Frank: kind of neutral character/narrator OR cumslut troublemaker
Bob: will sell you weed, lives in an RV
Gabe: subtlety gay guy who makes fun of the narrator
Hayley: v v spunky, also the cool kid OR the person who inducts you into a school cult
Billie Joe: kid you don't hear much about but is always doing weird shit, basically lives in the principal's office
Tyler: usually the narrator, timid and emotional
Mikey: homophobic rat ass that ends up banging Pete at the end OR shy kid that Pete annoys 24/7 OR adorable trans girl OR Gerard's childish brother
Pete: this annoying kid that calls people nicknames
Gerard: philosophical art geek
Ray: good guy that everyone talks to for support
Patrick: sweet kid, precious bunny
Lindsey: badass motherfucker that will stand with you forever
Brendon: flamboyant gay
Ryan: cute kid who likes milk too much
