I have a ML fanfic rec if you haven't read it already, Couturiere by hattafan2593 on AO3. It's a post-Chameleon salt fic, and it's good because Marinette is written as a terrifyingly competent akuma

I'll have to look into it, Anon! I've tossed it on my 'marked for later' list for now and can take a peek when I've time/am in the mood to read an ML fic. (It probably will be fun from the sounds of it? Akumatized!Marinette is always fun to think about.)

Admittedly, I'm automatically wary about something labelled a salt fic just because of how much salt is in the fandom in general, but there's a difference between a well-done version of how an episode could have gone (or aftermath thereof) and something that is...not.
