One idea could be a story where Peridot tries to prove her worth to Yellow Diamond in a non - traditional way. Maybe she discovers a new form of energy on Earth that could benefit the Diamond Authority, and she has to convince Yellow Diamond to give her a chance to explore it further.
A cool plot could be a fusion of their powers. Naruto's ability to create shadow clones and Peridot's technological skills could combine in an unexpected way. For example, the shadow clones could be used to operate Peridot's machines simultaneously, creating a super - efficient combat or construction strategy. Or perhaps Peridot uses her knowledge to upgrade Naruto's ninja tools, making them more powerful.
Their relationship could develop through mutual discovery. For example, Peridot could show Yellow Diamond the unique aspects of Earth that she has come to appreciate. Yellow Diamond, in turn, could share some of her knowledge of the Gem Homeworld with Peridot, creating a bond based on the exchange of ideas.
Maybe a time - travel plot where Steven, Peridot, Lapis, and Lemon are sent back to a crucial moment in Gem history. They have to work together to make sure the events unfold in a way that doesn't disrupt the present. Along the way, they learn more about each other's pasts and grow closer as a group.
A fanfiction could also focus on the origin story of how Yellow Diamond and Lemon met. It could be a chance encounter in a far - off land. They initially don't get along but as they face difficulties together, they start to understand each other and form an unlikely bond.
A great plot could involve a time - travel aspect. The protagonist is sent back to the time when Pokemon Yellow was first set, and they have to use their knowledge of modern Pokemon training and battling to change the course of history in the Pokemon world. They might also meet the original trainers from the game in a different way and form new alliances.
One idea could be exploring an alternate universe where the main characters have different Pokemon partners. For example, instead of Dawn having Piplup as her starter, she could start with a Chimchar. Another plot could revolve around a mysterious new Pokemon that only appears in a long - forgotten part of the Sinnoh region. It could be a Pokemon with unique powers that both the good and bad guys are after. Also, a story about a trainer who travels through Sinnoh backwards, starting from the Pokemon League and working their way to the beginning of their journey, facing challenges in reverse order.
A plot could revolve around a trainer who gets lost in a mysterious part of Sinnoh that is not on any regular map. In this area, they encounter Pokemon with strange behaviors and new evolutionary forms. The trainer has to figure out how to get back home while also learning about these new Pokemon, perhaps with the help of some local characters who have their own secrets.
One idea could be that Peridot and Amethyst are on a mission together and they start off bickering like they often do in the show. But as the mission progresses, they start to understand each other's strengths better. For example, Peridot's technical knowledge and Amethyst's physical power combine to defeat a new kind of enemy. Another plot could be them exploring a part of the Gem world they've never been to before and having to rely on each other to survive. Maybe they discover an ancient Gem relic that has the power to change the way Gems interact with Earth. This could lead to some really interesting character development as they figure out what to do with this new discovery.
Perhaps a fanfiction where the main character discovers a time - traveling device in the Pokemon world. They travel back to the very beginning of the Pokemon Red and Yellow era and have to prevent an event that would change the future of the Pokemon world in a bad way. Along the way, they meet the original Professor Oak as a young man and help him with his early Pokemon research.
One idea could be a story where the main character discovers a new, rare Pokemon in an unexpected place, like in a hidden cave in Viridian Forest. Another could be a fanfiction where the Pokemon trainers from Red and Yellow team up to face a new, powerful villain who has a unique ability to control Pokemon in a different way than the usual villains in the games. Maybe also a story about a trainer's Pokemon evolving in a very different way due to some strange phenomenon in the Kanto region.
