One common theme is the exploration of identity. In Homestuck, the characters already have complex identities, and in gay fanfic, this is often further explored in the context of their sexual orientation. For example, how they come to terms with being gay in a very strange and often dangerous world.
Friendship turning into love is another theme. Many Homestuck gay fanfics start with a strong friendship between two characters. As the story progresses, this friendship blossoms into a romantic relationship. This allows for a deeper exploration of the characters' connection and how it evolves over time, often with a backdrop of the Homestuck's unique and elaborate world.
One common theme is the exploration of different cultures. In both Steven Universe and Homestuck, there are unique cultures. In crossovers, it's interesting to see how the Crystal Gems' way of life and values interact with the trolls' or the kids' in Homestuck. For example, the idea of friendship and loyalty is strong in Steven Universe, and it can be contrasted or combined with the relationships in Homestuck.
Often, there are themes related to the Homestuck universe's overarching concepts. For example, the idea of fate and how their relationship fits into the grand scheme of things in the Homestuck story. Also, themes of friendship or something deeper evolving between them are quite common. Since Meulin is a rather curious character, her interactions with Kurloz can lead to themes of discovery, both of each other and of new aspects within the Homestuck world.
The exploration of Nepeta's growth as a character is also a common theme. As the Homestuck story progresses, Nepeta has her own character arc. Fanfictions may delve into her development, how she overcomes challenges, and how she changes over time. This can include her becoming more self - aware or learning to better interact with those around her in different situations.
Power and growth is also a common theme. In Naruto, characters are constantly striving to become stronger, and in Homestuck, the characters go through a lot of development. Fanfictions often explore how Naruto characters would develop in the Homestuck universe or vice versa in terms of power and personal growth.
One common theme is friendship evolving into something more. In Homestuck, there are many strong female friendships, and in Yuri fanfiction, these often develop into romantic relationships. Another theme could be the exploration of the characters' personalities in a more intimate setting, like how they interact with each other on a deeper level once they start having romantic feelings.
The theme of self - discovery also pops up a lot. The male characters in the yaoi fanfic might be on a journey to understand their own feelings and sexuality. It could be related to their experiences in the Homestuck universe, like dealing with the challenges they face in the game and how that affects their relationships with each other on a more personal, romantic level.
One common theme could be the exploration of new relationships. With Jade being pregnant, it might lead to changes in her relationships with other characters, like how they support her or deal with the new situation.
Love is a very common theme. It can be romantic love between the reader and a particular Homestuck character. This often involves a lot of fluff and sometimes some drama. Self - discovery is also a theme. The reader - insert often has to figure out who they are in this strange new Homestuck universe, what their powers are if any, and how they fit into the overall story. For instance, in some fanfictions, the reader discovers they have a special ability related to the Homestuck lore.
Adventure is also a big theme. Homestuck is a very adventurous story, and when a reader is inserted, they get to be part of all the crazy quests and battles. It's like going on a wild ride through the different planets and scenarios in the Homestuck world.
One possible theme could be about mystery. Maybe the 'cherry wine' is involved in some sort of mystery within the Homestuck universe, like it has a special power or is a key to a hidden place. Another theme could be romance. The 'cherry wine' might be something shared between two characters during a romantic moment.
