fandom is full of works regarding current and past politics and unions. This is (obviously) pretty much only feasible in this continuity, considering that the show is about personified countries
- The "Letters" trend: characters answering fanmail being sent to them (via reviews by readers). The strange thing about this is the fact that A) these typically don't require/have an actual plot, and B) interactive fanfic is actually against the rules on FF.net, but they manage to make up a VERY prevalent chunk of the APH category there. Occasionally sloppy research shows up, since some feature countries/cities/places that the authors do not hail from/have been to.
- There's also a developing trend in the form of "blogs": in others words: a country is forced to/secretly wants to make a blog and in the same vein as the letters fanfictions, answers the comments "posted" to the character's blog while at the same time providing an excerpt about that particular character's day or current thoughts, much like an actual blog.
- An APH fanfic writer's motto could practically be "If you look hard enough, any pairing can be historical." And it's generally true.
- The APH fandom is infamous for its Mpreg. Any geographic or administrative region could potentially have its own personification, and for some fanfic writers, there's no better way to Hand Wave in an OC than by having two characters go to town. Search in the right place and you will find Mpreg for any and every Hetalian.
- AU fanfics with the characters rewritten as ordinary people instead of countries are especially common, since they allow the author to write certain pairings/situations without any of the political/historical stickiness.
- AU fics in general are pretty common, normally coming in the form of Alternate History, For Want of a Nail and/or Dark Fic. Seeing how the characters (and their relationships/sanity) would be like in the future or had events played out differently from real life does allow writers certain freedoms with research.
- A wave of "Human-Finds-Out-About-Nations" fics has emerged on some websites. Depending on who writes it, this could be seen as either a good thing or something very, VERY wrong.
- The stereotypical Gerita story. One day, Germany finally realises he feels romantic feelings for Italy, tries to woo him, fails because Italy says "I'm waiting for someone" (HRE). Germany angsts until Prussia/Hungary/Austria/Whoever tells him he is Holy Rome! He tells Ita-chan, and they live happily ever after.
