Writers often characterize Giovanni as a complex character. He is still the powerful and somewhat menacing leader of Team Rocket. But in fanfictions with Delia, he may show a softer side. For example, he might be more hesitant to carry out his evil plans when Delia is around. He could also be shown as a bit more vulnerable, especially if he has feelings for Delia and is afraid of rejection or of losing her.
A common plotline is a love - triangle type situation. Giovanni has feelings for Delia, but Delia is in love with Ash's father (in some fanfictions). This creates a lot of drama and tension. Also, there could be a plot where Delia tries to reform Giovanni. She believes there is good in him and tries to convince him to use his power and resources for good in the Pokémon world instead of for the evil deeds of Team Rocket.
To develop Delia's character, we could show her interacting with Giovanni's world. She could start to understand the motives behind Team Rocket's actions, which changes her view of Giovanni. For Giovanni, we can develop his character by having him experience kindness from Delia. This could make him want to change his ways. Maybe he starts to think about using Team Rocket for good instead of evil. He could also be developed by showing his past traumas that led him to be the villain he is, and how Delia might be able to heal those wounds.
One interesting plot idea could be that Delia, Ash's mother, has some long - lost connection to Giovanni. Maybe they were childhood friends before Giovanni took the path of the villain. Another could be a story where Giovanni, for some reason, has to protect Delia from other evil forces in the Pokemon world, which turns into an unexpected alliance. And a third idea might be that Delia discovers a secret about Giovanni's past that makes her question her own understanding of good and evil in the Pokemon universe.
Giovanni is the menacing leader of Team Rocket in Pokemon. He has a reputation for being ruthless in his pursuit of powerful Pokemon and control over the Pokemon world. Arianna is a member of his organization. In fanfiction, she can be portrayed in different ways. Sometimes she's just a typical Team Rocket grunt, blindly following Giovanni's orders. But other times, she can be more complex. She might have her own reasons for being in Team Rocket, like a personal vendetta against a particular trainer or a desire for power that she believes Giovanni can help her achieve. She is often by Giovanni's side during his various escapades in the Pokemon world.
A more complex fanfiction could involve Ariana and Giovanni traveling to a new region in the Pokemon world. They could encounter new Pokemon species and form unexpected alliances with local trainers. This would be a great way to introduce new elements to the familiar Pokemon universe while still focusing on these two characters.
One common theme is the idea of redemption. Giovanni, being a villain in the main Pokémon series, often has a journey towards redemption in these fanfics, especially in relation to Delia. Another theme is the exploration of their different worlds colliding.
In Pokemon Ash and Delia fanfiction, the writers may also create new adventures for them together. Maybe they go on a special journey where Delia gets to see the Pokemon world from Ash's perspective. This can bring out new aspects of their characters and how they interact with each other.
A fanfiction could explore Delia and Johanna's pasts. Perhaps they both had dreams of being great Pokemon trainers themselves when they were young. But due to various circumstances, they couldn't fully pursue those dreams. Now, through their children's adventures, they see a bit of their own lost youth. They could bond over these shared experiences, and maybe even start training a bit themselves again, with their old Pokemon that they still keep, inspiring their children to new heights in their Pokemon training.
One possible fanfiction could involve Giovanni using his cigar as a symbol of power. In the Pokemon world, Giovanni is a feared and respected figure. His cigar might be seen as a way to intimidate others during his underworld dealings. For example, when negotiating with other villainous teams, he takes long puffs on his cigar, creating an air of mystery and danger.
