One great fanfic could be one where Aquamarine and Lemon team up for an unexpected adventure on Earth. Maybe they start off as antagonists but end up as friends. It could involve them exploring human culture and having humorous misunderstandings along the way.
A good fanfic should have well - developed characters. For Aquamarine and Lemon, it means exploring their personalities beyond what we see in the show. Maybe giving Aquamarine a more vulnerable side and Lemon a more determined streak.
A time travel fanfiction could involve a character other than Steven, like Connie. She could travel back in time to meet Rose Quartz. This would be an interesting encounter as Connie could ask Rose about her past, her relationship with Greg, and her hopes for Steven. It could also create a situation where Connie has to make sure she doesn't accidentally change the past in a way that would harm the present.
If it was a crossover with "She - Ra and the Princesses of Power", Adora could be a main character. Her strong leadership and the power of She - Ra would be an interesting contrast to Steven's more laid - back leadership style. Together, they could fight against a common enemy that threatens both their worlds.
One idea could be a crossover with "Adventure Time". Finn and Jake could visit Beach City and interact with the Crystal Gems. They could go on a mission together to stop a new threat that combines the magic of both universes.
One common theme is self - discovery. When a character travels through time, they often learn more about themselves. For example, Steven might travel back to a time when he was younger and realize how much he has grown. Another theme is fixing past mistakes. Maybe a character goes back to prevent a certain event that had negative consequences in the future.
It could be a corrupted Gem from the past that was somehow locked away and now resurfaces in the future, angry at the changes that have occurred. This Gem might not understand the new world order and wants to return things to how they were.
Yes, there are likely fanfictions out there that might feature a kiss between Steven and Lapis. The Steven Universe fandom is quite creative, and fans often explore different relationship dynamics in their fan - made stories. However, the official show may not have such a scenario, but fanfiction allows for all kinds of interpretations and romantic pairings that deviate from the main plot.
Well, one aspect could be the unique relationship between Peridot and Steven in the fanfic. Peridot is such an interesting character with her growth and development throughout the series, and when paired with Steven, there can be many new storylines. Maybe it focuses on their friendship deepening into something more, or perhaps it's about them going on adventures together that are different from the main plot of the show.
