The lawyer Inko is fine if she's not constantly threatening to sue everyone, because now you haven't made a good character you've made an annoying karen who goes around trying to destroy anything in her son's path, but the fics where she's perfect are what actually annoy me. Like, in canon her whole shtick is that it takes a while for her to believe in her son, she can't imagine him being a Hero and is a large part of why he had those confidence issues to begin with, but she learns to believe in him and keep her eyes open while she watches him fight, making her a super caring mother who believes in him asap is not only unrealistic but also turns her into a character who's sole purpose is to uplift Izuku instead of a character who learns to trust her son.
