hmm. i can't think of too many but like i think the most major one i'm not fond of is the persona 3 protagonists as twins. i actually use to like this one too, but it fell out of favour with me sometime last year. i just kind of prefer them as parallel versions of each other over anything else? i think the idea of like "ahh they're twins and your choice as the player is which twin lives" is like neat in theory but not something i find especially compelling

i do kind of take issue with a bunch hcs but most of them are like. sexuality hcs i disagree with or individual interpretations of characters that i have no idea the popularity of. oh but i do really dislike addict shinjiro jokes. that shit pisses me off that's not drug addiction bro he needs those to not get killed by his own persona or risk someone else dying to it that's just not how addiction works

oh and the. akihiko is makoto nijima's father hc. which i think is more of an acknowledged au than a hc (it just doesn't mesh at all with the timeline like let's be so fr here) but i just don't like it either way i'm ngl. also not a fan of the baofu is futaba's father hc because umm. idk i just don't think post-EP baofu is going to absent father someone like that
