One possible plotline could be that Richie Rich, with his vast wealth, throws a grand party and Audrey is invited. At the party, they discover they have a shared love for art. Richie then uses his resources to take Audrey on a tour of the world's most exclusive art galleries.
It could be another wealthy kid who is jealous of Richie's attention towards Audrey. This antagonist might try to sabotage their relationship by spreading false rumors about Audrey, saying she's only interested in Richie's money.
One possible plotline could be the family's reaction. The Weasley family is large and close - knit, so they would likely be very excited and supportive. There could be scenes of them preparing for the new baby, like knitting baby clothes or setting up a nursery. Another plotline might involve Audrey dealing with the physical and emotional changes of pregnancy while also managing her daily life in the wizarding world.
One possible plotline could be a story of conflict and reconciliation. Giratina, often seen as the 'evil' or 'banished' Pokémon, might have some sort of misunderstanding or old grudge against Arceus, the creator. The fanfic could explore how they gradually come to understand each other's perspectives. Maybe there's a threat to the Pokémon world that only they can face together, forcing them to put aside their differences.
It could also be a fanfic that takes place in an alternate universe. In this universe, the events of 4x23 didn't happen as they did in the show. Maybe Beckett didn't become a detective in the same way, and Castle meets her in a completely different situation. They then start to solve mysteries together in this new setting.
One characteristic is the exploration of their friendship. Since they are both Pokemon trainers, the fanfic often shows them sharing tips and training methods.
Perhaps in some fanfics, Pikachu and Sparky could be from different regions and they meet by chance. Their different backgrounds and abilities could lead to an interesting story as they learn from each other and overcome difficulties. For example, Sparky might be from a region with different types of electric - type Pokémon techniques that Pikachu has never seen before, and they could exchange knowledge. This could also lead to a deeper emotional connection between them as they grow to respect and care for one another.
Another plotline could involve Ben and Albedo being forced to team up against a greater threat. They would have to put aside their differences and work together, which could lead to some interesting character dynamics as they learn more about each other.
One possible plotline could be that the trainer is on a quest to find and capture Raikouf. Along the way, they face numerous obstacles like other powerful Pokémon or rival trainers. Another plot could be that the trainer already has Raikouf and they are training it to become the strongest in a certain competition, like a Pokémon league.
Perhaps in a fanfic, Pirika and Hao are both involved in a mystery. As they work together to solve it, they start to develop feelings for each other. They might discover secrets about each other along the way that either bring them closer or create some temporary rifts in their relationship.
A possible plotline could be that Naruto is transported to Maleficent's world. He might initially be seen as a threat but then prove himself to be an ally. Together, they could fight against the dark forces in Maleficent's world that are trying to take over the entire realm.
