What are some interesting plot ideas for 'pokemon gold x ruby fanfiction'?

One idea could be a story where the protagonist's Pokemon from Pokemon Gold teams up with a Pokemon from Pokemon Crystal to face a new, powerful and mysterious threat that neither region has seen before. For example, a dark force that is causing natural disasters in both Johto and the Crystal region.

One idea could be exploring an alternate timeline where the main character makes different choices. For example, choosing a different starter Pokemon and how that changes their entire journey. Another could be focusing on the backstories of the Gym Leaders in the Pokemon Gold game, like what led them to become Gym Leaders.

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.

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 different landscapes and Pokemon of the two regions would add a lot of variety to the story.

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.
