For Kyogre, it could be characterized as a powerful but somewhat solitary being. It's protective of the oceans and views any threat to the seas as a direct attack. It's majestic and its movements are fluid like the waves. Groudon, on the other hand, is a force of the land. It's stubborn and proud, believing that the land is the most important part of the world. It's slow to trust but once it does, it's a loyal ally.
In a fanfic, Groudon can be seen as a proud and territorial being. Since it represents the land, it guards its territory fiercely. It has a sense of honor and dignity associated with its role as the keeper of the earth. Kyogre can be characterized as a wise and ancient entity. It has seen the ebb and flow of countless years beneath the ocean waves. It is patient but when provoked, it can call upon the power of the entire ocean to defend itself. They both can be shown as having a mutual respect for each other's power deep down, even though their natures often put them at odds.
A great fanfiction idea could be a time - travel story involving Groudon and Kyogre. A trainer travels back in time to the era when Groudon and Kyogre first started their feud. The trainer tries to prevent the feud from ever starting, but in doing so, he accidentally disrupts the balance of nature in that time period, leading to new and unexpected challenges.
One possible scenario in a Groudon and Kyogre fanfiction could be a story where they are forced to team up against a greater threat. Maybe a new, extremely powerful Pokemon emerges that threatens to destroy their habitats. Groudon, the land Pokemon, and Kyogre, the sea Pokemon, must put aside their age - old rivalry to save the world they both call home.
A plot could also revolve around a new type of power - enhancing crystal that has been discovered. Kyogre and Groudon both want it to boost their own strength. A group of trainers get caught in the middle of their struggle. They have to figure out a way to either stop the two Legendary Pokemon from fighting over it or find a way to share the crystal's power between them to maintain the balance in the world.
One idea could be that Groudon and Kyogre are forced to team up against a new, greater threat that endangers the entire Pokemon world. This could be a powerful, ancient Pokemon that has been awakened. Another plot could be a story where a trainer tries to understand the relationship between Groudon and Kyogre through a series of dreams and adventures, and in the process, discovers a hidden power that lies within their connection.
To develop Groudon in the fanfiction, you could give it a backstory about how it has always felt alone in its role of protecting the land, which has made it a bit of a loner. When it meets Kyogre, it's full of distrust. But as they are forced to interact more, Groudon starts to see the value in Kyogre's power over the ocean. For Kyogre, it could be developed as a character that has a strong connection to the emotions of the sea. It might initially view Groudon as a threat to the delicate balance of the world. However, through shared experiences, like being trapped in a strange dimension together, Kyogre realizes that Groudon is not just a brute force of the land but has its own kind of wisdom. Other characters in the story, such as mythical Pokemon or powerful trainers, can also play a role in their development. For instance, a mythical Pokemon might give them a task that requires them to work together, and in the process, they grow and change.
One interesting plot idea could be that Groudon and Kyogre are forced to team up against a new, greater threat that endangers their respective habitats. Maybe a powerful alien - like Pokemon arrives on Earth and starts draining the oceans and drying up the land simultaneously. Another idea is a story where a young trainer has the ability to communicate with both Groudon and Kyogre and tries to broker peace between them, as their eternal struggle is causing chaos for the people and other Pokemon. Or perhaps a plot where Groudon and Kyogre discover they are part of an ancient prophecy and must combine their powers in a specific way to save the world from a cataclysmic event.

Once, I was at a concert. There was a couple in front of me who seemed to be having their own little dance party. They were completely out of sync with the music and each other. The guy was doing some really wild moves, and the girl was trying to be all elegant. It was a strange and funny sight. People around were trying not to laugh out loud, but it was really hard.
