oh this is a good question...2 that come to mind immediately are a punk au because op characters fit into that so well especially the captain trio and i COULD write it but every time i really think about it for some reason my brain just goes Nah. the other is a space horror fic along the lines of something like event horizon or dead space just because i'm not very smart when it comes to scifi stuff even tho i enjoy it so it'd just take way too much time and energy for me to feel like i was doing it any sort of justice
