Sometimes, other trainers or characters from the Pokemon world might make appearances in the fanfiction. They could be friends, rivals, or mentors to Roark and Gardenia. For example, another trainer might challenge them to a double battle, or an older and more experienced trainer could give them advice on how to better train their pokemon.
It could be a story where Gardenia, a character from Pokemon, gets tickled in some comical situation. Maybe she's in her garden and a small Pokemon accidentally tickles her while playing around her plants.
Their relationship could develop through mutual respect for their love of Pokemon. For example, James might show Gardenia some unique ways he's found to care for Pokemon during his travels, and Gardenia could teach him more about the nuances of grass - type Pokemon.
In some fanfictions, there could be a story about their friendship development. Maybe they start off as rivals, with Roark being more focused on the strength of his pokemon and Gardenia on the unique abilities of hers. But as they interact more, they realize they can learn from each other. They could exchange training techniques and even help each other in pokemon battles against common enemies.
It's possible that the story is set during a Pokemon contest. Gardenia is competing, and her rivals come up with a creative strategy to distract her by somehow causing a tickling sensation. This could create a lot of drama and humor in the story. Maybe they use a combination of Pokemon moves and items to achieve this. As a result, Gardenia has to find a way to overcome this distraction and still perform well in the contest, adding an interesting twist to the plot.
Their relationship could start with mutual respect for each other's skills with Pokemon. Ash is known for his battling prowess and Gardenia for her knowledge of Grass - type Pokemon. They might begin by exchanging tips on training and caring for Pokemon. Then, as they spend more time together, they could develop a friendship based on shared adventures. For example, going on a quest to find a rare herb that can heal sick Pokemon.
They could develop their relationship by sharing their dreams. Ash could talk about his goal of becoming a Pokemon Master, and Gardenia could share her dreams of making her gym the best in the region. By supporting each other's dreams, they form a stronger bond. For instance, Ash could help promote Gardenia's gym while Gardenia could give Ash some special training for his Pokemon.
Perhaps a plot where Gardenia has a special Pokemon that is sick, and Ash, with his experience in traveling and helping Pokemon, offers to help. They go on a quest to find a rare herb that can cure the Pokemon. Along the journey, they encounter other trainers who are also in need of help, and they have to decide whether to focus on their own mission or help others first.
One plot idea could be that James and Gardenia team up to save a rare Pokemon from a poacher. They start off not getting along but gradually learn to respect each other's skills.
Perhaps there's a plot where Gardenia challenges Ash to a friendly battle. But during the battle, an unexpected event occurs like a sudden storm or the appearance of a wild, powerful Pokemon. They then have to put their battle on hold and cooperate to deal with the situation. Afterward, they realize that they have a lot more in common than they thought and start to explore a romantic relationship.
