Why is most none rule 34 Adult Frisk fanart so adorable? Maybe it’s just the knowledge that despite everything that happened and all of the shit he went through, he still grew up to be a happy well-adjusted adult/teenager.

I think it has to do that most of them use the psychotic Chara instead. Or just Papyrus breaking character hard enough to dispel suspension of disbelief/misdirection of erection.

(I have to give them, they still do a very decent job of keeping Frisk/Chara gender-incognito)
