A plot could also revolve around Ash's father being a time - traveler. He goes back and forth in time, and at some point, his actions in the past accidentally change the present where Ash lives. So, Ash has to find a way to work with his father to set things right and restore the proper timeline.
One plot idea could be that Ash's father was exiled from their town for a crime he didn't commit. The fanfiction could follow his journey to prove his innocence and his attempts to reunite with his family. Along the way, he could encounter unique Pokémon and make new friends who help him in his quest.
Another interesting plot could be a time - travel story where Ash and Cynthia are sent back in time to the early days of the Pokémon world. They have to adapt to the different rules and ways of training Pokémon back then while also trying to find a way back to their own time.
One plot idea could be that Ash is captured by a new and powerful villain who wants to use his Pokémon knowledge for evil. Another could be that he's captured by a group who mistake him for someone else and he has to prove his identity while trying to escape. Maybe he's captured by an ancient Pokémon that has some sort of grudge against trainers and he has to convince it that not all trainers are bad.
Another plot could involve a Pokémon contest where May is a contestant and Ash is there to support her. But something goes wrong with the contest rules due to a villain's interference. Ash and May then team up to expose the villain and make sure the contest is fair for all the contestants. It could also be a chance for their relationship to grow deeper as they face challenges together.
One idea could be Ash encountering a Legendary Pokemon that has lost its memory. Ash then tries to help it regain its memories while protecting it from poachers. Another could be a time - travel plot where Ash is sent back in time and has to team up with a Legendary Pokemon to prevent a great disaster from happening in the past that would change the future of the Pokemon world.
Here's a plot idea. Ash attends a Pokémon - centered festival where he meets a girl named Ella who is a talented Pokémon artist. She draws pictures of Pokémon based on the stories she hears from trainers. Ash starts sharing his own adventures with her, and she creates beautiful art inspired by his tales. As they interact more, Ash realizes he has feelings for Ella. However, there are some who oppose their relationship because they think Ash should focus solely on training. But their love overcomes these obstacles as they prove that love and Pokémon training can co - exist.
Another plot could be set in a world where a strange phenomenon is affecting Pokémon. Ash and Cynthia join forces to investigate. Along the way, they discover a new type of Pokémon evolution that has been hidden for centuries. As they work together, they start to develop a deep friendship that might turn into something more.
In some Pokemon fanfictions, there could be creative interpretations where Ash is made out to be Red's father. However, in the official Pokemon canon, there is no such relationship between them.
Perhaps Ash gets a special ability from a Legendary Pokémon, like the ability to communicate telepathically with all Pokémon. This causes him to be hunted by an organization that wants to use this power for their own gain. With the help of various Legendary Pokémon that he befriends on his journey, Ash has to protect himself and his new power.
A really interesting plot might be that Ash is chosen by an ancient dragon deity to be its champion. As a Dragon Master, he has to go on a quest to collect special dragon orbs scattered across different regions. Each orb gives him new powers or abilities related to dragon Pokémon. Along the journey, he faces challenges from other trainers who also want the orbs for their own purposes.
Another idea is that the discovery of Giovanni as his father makes Ash question his own identity and place in the Pokémon world. He might have to reevaluate his goals and his relationships with other characters. Meanwhile, Giovanni could be faced with the challenge of trying to make amends or trying to bring Ash into his world in a more positive way.
