What are the common themes in 'Steven Universe Homestuck Crossover Fanfic'?

One popular 'Steven Universe Homestuck Crossover Fanfic' is 'The Gemstuck Adventures'. It combines the unique worlds of Steven Universe and Homestuck in an interesting way. The characters from both universes interact in unexpected ways, like Steven meeting the trolls. Another one could be 'Fusion of Universes' which focuses on how the powers and concepts in both shows blend together.

One common theme is family. Since they are father and son, a lot of fanfics explore their family bond, how they understand each other, and grow together. For example, stories might show Greg teaching Steven about his human heritage.

Friendship is a very common theme. Many fanfics explore how Sadie and Lemon support each other, like in 'Sadie and Lemon: True Friends' where they are always there for one another through good and bad times.

One common theme could be self - discovery. Lapis has a complex backstory and many fanfics explore how she continues to learn about herself. Another theme might be friendship, as she forms bonds with the other characters in the 'Steven Universe' world.

Another possibility is that a Marvel hero, say Spider - Man, accidentally ends up in Beach City. He teams up with Steven to deal with a local threat that is also related to some sort of interdimensional chaos. For example, a group of villains from the Gem world and the Marvel world are working together to open portals to other dimensions to steal valuable resources. Steven and Spider - Man would have to use their unique abilities to stop them.

One common theme is acceptance. Since Greg and Pearl are very different characters, a lot of fanfics focus on them accepting each other's differences. For example, Pearl's more formal and uptight nature compared to Greg's laid - back style.

Adventure is also a common theme. They go on different quests or face various threats together. This could be something like exploring an ancient gem ruin on Earth or fighting off a new enemy. The theme of acceptance is important too. Accepting each other's flaws and differences. Amethyst accepting Steven's sometimes naive view of the world, and Steven accepting Amethyst's wilder side.

One popular theme could be exploring different relationships. For example, how a female Steven would interact with the existing characters like Pearl, Amethyst, and Garnet. Maybe she'd have a different dynamic with them, bringing out new sides of their personalities. Another theme might be self - discovery. Since Steven in the original series has a journey of understanding himself and his powers, a female Steven could have a similar yet distinct journey, perhaps facing different challenges due to being female in the Crystal Gem world. Also, themes of friendship and loyalty are likely to be explored, as they are central to the 'Steven Universe' series.

One possible theme is growth. Both Peridot and Steven grow throughout the original series, and the fanfic could continue that growth in their relationship. They might learn to understand each other better and become stronger individuals as a result.

To write this kind of fanfic, start with a strong hook. Maybe start with Steven waking up in the Underground or Frisk arriving on Earth near Beach City. Then, build the story gradually. Show how the characters react to the new environment and each other. Don't forget to add some action and conflict. It could be a battle between the Gems and some of the more aggressive monsters from Undertale. And make sure to stay true to the essence of both universes. Don't change the core personalities of the characters too much. This way, fans of both shows will be able to enjoy your fanfic.
