What are some interesting plot ideas for a Pokemon Champions League fanfiction?

Another plot idea is to have a story centered around a Pokemon that has been misjudged in the Indigo League. Maybe it's a dark - type Pokemon that everyone assumes is evil. But the main character, a trainer, sees its potential and trains it to become a champion - level Pokemon. The trainer has to overcome the stigma associated with the Pokemon type and prove that it can be just as strong and noble as any other Pokemon.

One idea could be a story about an underdog trainer who enters the Master League with a team of rare but not-so -popular Pokemon. They face all kinds of challenges and discrimination from other trainers who have more common and 'powerful' Pokemon. But through their unique bond with their team, they start to surprise everyone and make it far in the league.

One idea could be a trainer with an underdog Pokémon that has a unique ability not fully understood yet. They face many challenges in the Kalos League but gradually learn to harness that ability to surprise opponents. For example, a trainer with a Skitty that has a hidden psychic ability.

One idea could be a trainer from a small, unknown town who enters the Pokemon Champion League with an underdog team of Pokemon. Another could be a story about a former champion who comes back to reclaim their title after a long hiatus. Maybe a story where a trainer has to face unexpected challenges during the league, like a new type of Pokemon or a rule change.

Well, perhaps the 'Game of Champions' is a battle royale - style event where there are no rules except that the last trainer standing with at least one Pokemon wins. Trainers can form temporary alliances but they can also break them at any time. The main character could be a trainer who is known for his kindness towards Pokemon and he has to use that to his advantage. He might befriend some wild Pokemon in the arena who then help him in battles against the more cut - throat trainers.

Ash could encounter a legendary Pokemon in the Unova League that decides to help him in his battles. This would be a huge advantage and also a great plot twist.

One idea could be a new challenger arriving in the game world. This character has a unique power that no one has seen before. They start from the bottom but quickly rise through the ranks, making friends and enemies along the way.

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.

A young inventor - trainer. This character is constantly modifying Pokeballs to give their Pokemon unique advantages in battles. For example, a Pokeball that releases a small burst of energy to boost their Pokemon's first attack in a battle. They enter the Champions League with their homemade gadgets and their trusty Pikachu, which they have trained to use electric attacks in new and creative ways.

One plot idea could be a story where a trainer forms an unexpected bond with Reshiram. Maybe the trainer is initially afraid of Reshiram's power but over time they learn to work together and understand each other.
