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.
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.
To develop Groudon's character, you could focus on its fiery nature. Show how it's not just about destruction but also about the renewal of the land. For Kyogre, emphasize its connection to the vastness of the ocean and its role in maintaining the balance of marine life. You could give them internal thoughts, like Groudon might be frustrated with always being seen as the one causing droughts, and Kyogre with being blamed for floods.
Sometimes, other Pokémon can be main characters as well. For instance, Pokémon that are associated with water or earth might play important roles. They could be friends or foes of Kyogre and Groudon, depending on the plot. But ultimately, Kyogre and Groudon remain the central focus as their relationship and power dynamics are what the fanfiction is usually about.
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.
One popular 'kyogre x groudon fanfic' is 'The Clash of Titans'. It really delves into the relationship between Kyogre and Groudon in a unique way. The story sets up an interesting scenario where they have to work together despite their natural enmity. It's full of action and also some great character development.
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.
The theme of redemption can also be present. Maybe one of them has caused some kind of destruction in the past, and through their relationship with the other, they find a way to make amends. It could be Groudon's volcanic eruptions or Kyogre's tsunamis that they need to atone for, and their bond helps them in this journey of redemption.
There might be a story where Kyogre and Groudon are forced to work together. They start off as enemies but as the story progresses, they learn to respect each other's strengths. For example, Kyogre's control over water helps put out fires caused by Groudon's volcanic activities, and in return, Groudon provides land for Kyogre's sea creatures to rest on during low tides. This shows their growth from antagonists to allies in the fanfiction world.
