A plot could revolve around a group of trainers who team up to stop an evil organization from using a powerful ancient Pokemon from the Emerald lore to take over the region. They would have to face various challenges and overcome their own personal differences along the way. For example, one trainer might be more focused on catching Pokemon for personal gain, but through the adventure, learns the importance of teamwork and protecting the region.
One idea could be a story where the main character discovers a new, hidden type of Pokemon in the Emerald region. This Pokemon could have unique abilities that disrupt the existing power balance in battles.
Another interesting plot could be a Pokemon Emerald fanfiction where the main character is a Pokemon researcher who stumbles upon a strange phenomenon that is affecting the behavior of Pokemon in the region. As they investigate, they find that it is related to an old, forgotten legend about a powerful crystal that has the power to control Pokemon minds. The character then has to race against time to find and stop whoever is misusing this crystal before all of the Pokemon in the Emerald region are under its control.
One idea could be a trainer starting with a randomized starter that has an unexpected type combination, like a Fire/Grass type. This would lead to unique battle strategies and interactions with other trainers. Another could be a story where the Pokemon world's geography is randomized too, so the trainer has to navigate through unfamiliar terrains.
Another interesting plot could be that the main character's Pokemon start to develop strange behaviors. It turns out that there is a mysterious force in the region that is affecting their minds. The character has to embark on a journey to find the source of this force and stop it before it causes chaos among all Pokemon.
A great plot could involve a Pokemon that has the ability to travel between the Emerald and Ruby regions at will, causing chaos as it steals rare items. The fanfic could follow the journey of two trainers, one from each region, as they try to track down this Pokemon and return the items. They start off as rivals but gradually learn to work together. The different landscapes and Pokemon of the two regions would add a lot of variety to the story.
One idea could be exploring the backstories of the characters in more depth. For example, delving into their past relationships, traumas, or what led them to be in the situation during the Emerald Twilight. Another could be a 'what if' scenario, like what if a different character had made a crucial decision during that time. Maybe a fanfic where a minor character steps up and changes the course of events.
One idea could be the main character being reborn as a Pikachu and having to navigate the world with its electric powers while making friends with other pokemon. Another could be being reborn as a Eevee and having the unique ability to evolve into any form at will, which causes both envy and admiration among other pokemon. Maybe the reborn pokemon has memories of being a human and uses that knowledge to outwit trainers and other threats.
One idea could be a quest to find all the Chaos Emeralds in a post - apocalyptic world where the power of the emeralds is the key to restoring order. Another could be a story where a new character discovers they have a special connection to the Chaos Emerald Z and must learn to control its power to defeat an ancient evil.
An interesting plot for a Pokemon Conquest fanfiction could be a tale of a trainer who loses their memory but still has an innate connection with their Pokemon. As they journey through the kingdoms, they slowly start to regain their memories through their Pokemon battles and interactions. Another plot could involve a forbidden love between trainers from rival kingdoms, and how they try to keep their relationship a secret while also dealing with the pressures of their kingdoms' expectations. You could also create a fanfiction where a new type of Pokemon emerges, and all the kingdoms are vying to be the first to tame and control it, leading to a series of intense battles and political intrigue.
One idea could be exploring an alternate universe where the protagonist starts with a rare and unique Pokémon that's not available as a starter in the original game. Another could be a story about a Pokémon trainer who has the ability to communicate with Pokémon in a more in - depth way than normal, and how that changes their journey in the Unova region. Maybe a fanfiction about a group of Pokémon trainers coming together to solve a mystery that threatens the balance of the Unova region.
A plot could revolve around a Pokemon RPG fanfiction where the main character is a Pokemon breeder who accidentally creates a new form of an existing Pokemon through a special breeding technique. This new form causes a stir in the Pokemon community, and the breeder has to deal with the consequences, like people trying to steal the Pokemon or Pokemon professors wanting to study it.
A more adventurous plot could involve an Audino that gets separated from its natural habitat and has to team up with a trainer to find its way back. Along the way, they face various challenges and encounter different Pokemon species, and the Audino discovers new strengths within itself. This plot could also explore the relationship between the Audino and the trainer as they grow closer during their journey.
