A great fanfic might explore their relationship in the context of Olympian politics. Maybe there's a power struggle among the gods, and Apollo and Hermes have to rely on each other. Apollo's prophetic abilities combined with Hermes' wits could make for an exciting plot. They could outwit other gods who are trying to gain more control over the mortal realm.
One characteristic could be the exploration of their personalities in a more intimate way. Since it's a 'lemon' fanfiction, there would likely be a lot of focus on their emotions towards each other on a romantic and sexual level. However, this also means that it may deviate from the traditional interpretations of the Greek gods. Another aspect could be the setting. It might be set in the world of Greek mythology, but with a modern twist in terms of how the relationship is portrayed, perhaps with more contemporary views on love and relationships.
Since 'lemon' fanfiction often contains inappropriate content, we should focus on general themes in Hermes and Apollo fanfiction. A common theme is their rivalry. In Greek mythology, they both have their own areas of expertise and there are stories where they compete. Another theme could be their brotherly relationship as they are both sons of Zeus. They might support or oppose each other in different mythological events.
One interesting story could be about their adventures together in the realm of the gods. Apollo, with his musical talents and Hermes, with his speed and cunning, might go on a quest to retrieve a lost magical artifact. They could face various challenges along the way, like outwitting a tricky nymph or solving a riddle set by an ancient spirit.
Some Tumblr blogs are also dedicated to sharing and discussing fanfics. You can search for Apollo Hermes - related tags on Tumblr, and you might come across some hidden gems. These blogs often have a community of fans who are passionate about the same characters and may recommend some really good fanfic that you won't find elsewhere.
There might be some out there. You could start by checking fanfiction platforms like Archive of Our Own. However, keep in mind that 'lemon' often implies mature or sexual content, which may not be suitable for all audiences. Some platforms have strict rules against such content, so it could be a bit tricky to find exactly what you're looking for in a proper and acceptable way.
One idea could be that Apollo and Hermes team up for a musical competition across the realms. Apollo uses his musical talents and Hermes uses his speed to spread the word and gather audiences. Another could be a story where they swap their powers for a day and have to deal with the consequences. For example, Hermes struggles to control Apollo's sun - chariot while Apollo has a hard time with Hermes' winged sandals.
The relationship can also be portrayed as a mentorship of sorts. Hermes, being the younger god, could look up to Apollo in certain aspects like art and prophecy. He might ask Apollo for advice on how to create beautiful melodies (even though Hermes is more known for his flute). Apollo, in turn, could be impressed by Hermes' quick thinking and ability to get out of tight situations, and learn from him in terms of adaptability. This dynamic would add an interesting layer to their relationship in fanfiction.
The contrast between Apollo and Hermes' personalities makes it interesting. Apollo is often associated with the sun, light, and order, while Hermes is the messenger, more associated with trickery and speed. Their interactions in fanfiction can be full of tension and unexpected turns.
Yes, there are quite a few. You can start by looking on popular fanfiction websites like Archive of Our Own. Just search for 'ares x apollo' and you'll find a variety of stories with different themes, from friendship - based ones to more romantic interpretations of their relationship.
