Gender Bending Library -- Faylen's fics
Fics in which the main characters (Focus on Tony) gender is switched/different from canon or the normal popular canon. Can include trans fics too.
When it's focus on Tony it would be Female Iron.
Then there's those interesting fics which I like in which he's been a different gender before becoming Tony, and finding his way to deal with it. (Being Hela, the dragon queen thingy and I'm sure there's others)
