One idea could be exploring an alternate universe where the starters of Ruby and Sapphire have different evolutions. Another could be a story focused on a side character from the manga, like giving a backstory to a Gym Trainer. Maybe also a story where the legendary Pokemon Groudon and Kyogre form an unexpected alliance instead of their usual rivalry.
Well, you could do a fanfiction where a trainer in the Ruby and Sapphire manga world discovers a new, never - before - seen Pokemon. This new Pokemon could have unique abilities that disrupt the balance in the Hoenn region. Or perhaps a story where a group of villains has a different motive than the usual Team Aqua or Magma, like trying to steal all the Pokemon's unique moves. You could also write about a trainer who gets lost in an uncharted area of the Hoenn region and has to rely on their wits and the help of some friendly wild Pokemon to find their way back.
A really interesting plot for a Pokemon Ruby and Sapphire fanfiction could be set in an alternate Hoenn region. In this version, the roles of certain Pokemon types are reversed. For example, Water - type Pokemon are rare and Electric - type Pokemon are the dominant force in water - based areas. The main character could be a trainer who has to adapt to these new rules. They might have to find creative ways to battle and train their Pokemon. This could lead to some really unique and exciting adventures, as they encounter different challenges and make new friends and enemies along the way.
One idea could be exploring a new mega evolution for a less - known Pokemon in the Hoenn region. For example, making Linoone have a mega evolution with a unique design and new abilities.

This could lead to a race among different trainers and teams to either protect or capture it.
One idea could be focusing on a trainer who is trying to reunite the two legendary Pokemon of Ruby and Sapphire, Groudon and Kyogre, to stop a greater threat that emerges when their power imbalance causes natural disasters. The trainer has to travel across both Hoenn regions, facing challenges from different gym leaders who have different views on how to handle the situation.
One interesting Ruby and Sapphire Pokemon fanfiction could be about a trainer's journey through the Hoenn region with a unique team composition. For example, a story where the trainer focuses on raising underrated Pokemon from Ruby and Sapphire like Lombre or Lotad and turns them into powerful partners. This kind of fanfiction often adds a fresh perspective to the well - known Pokemon adventure in the Hoenn region.
Perhaps a fanfic could be about a Pokémon from Ruby and Sapphire that gets lost in a different region. The Pokémon has to find its way back home while making new friends and facing challenges in the unfamiliar environment. Along the way, it could encounter different trainers and Pokémon species, and the story could show how it adapts and overcomes obstacles to return to Hoenn.
One interesting plotline could be a trainer's journey in the Hoenn region with a unique team composition. For example, a trainer might focus on using only underrated Pokemon to prove their strength. Another could be a story about the relationship between the legendary Pokemon in Ruby and Sapphire, like how Groudon and Kyogre's rivalry affects the region. And there might also be a plotline where a character discovers a hidden power within themselves while exploring the Hoenn region's mysteries.
One interesting plot could be a trainer's journey to discover a rare and powerful Pokemon that is said to exist only in the Ruby and Sapphire regions. They face many challenges and meet unique characters along the way.
In the fanfiction, Ruby and Sapphire could be having trouble adjusting to life in a new town. Steven, who has experience with change, could introduce them to new friends and show them all the fun things about the place. Meanwhile, they could teach Steven more about their unique Gem culture, like how they fuse and their special powers. This would create a story full of cultural exchange and friendship building.
One plot idea could be that Sapphire and Ruby are having a disagreement about how to best protect Steven. Sapphire, with her future vision, sees a potential threat approaching in a very different way than Ruby does. This leads to some tension between them as they try to figure out the best course of action for Steven's safety.
One idea could be to focus on a trainer who discovers a rare and powerful Pokemon in an unexpected part of the Hoenn region. Maybe a Pokemon that was thought to be extinct.

Or perhaps a story about a Pokemon trainer who befriends a Pokemon that has trouble evolving and they go on a journey to find a special way to make it evolve.
