Well, in such a fanfiction, the plot could start with Ash finding some old documents or having a strange encounter that hints at his relation to Giovanni. As the story unfolds, Giovanni might try to secretly protect Ash from other villains in the Pokémon world while still maintaining his public image as a bad guy. Meanwhile, Ash could be on a journey to not only become a Pokémon master but also to understand his father better and perhaps change him for the better.
The plot could be really complex. Maybe Ash has always felt an unexplained connection to Team Rocket's actions. When he discovers Giovanni is his father, he could be initially in denial. Giovanni, for his part, might have had reasons for keeping his identity a secret all these years, like protecting Ash from his enemies. The fanfiction could then explore how Ash and Giovanni's relationship develops over time, with Ash trying to make Giovanni see the error of his ways and Giovanni struggling with his new role as a father while still being the head of Team Rocket.
One possible plot could be Ash gradually discovering the truth. He might start noticing strange similarities between himself and Giovanni. Then, Giovanni could be torn between his role as the leader of Team Rocket and his newfound feelings for his son. Ash, on the other hand, would have to grapple with the idea of his father being a villain.
In this fanfiction, it could lead to a lot of interesting plot twists. For example, Ash might have a natural inclination towards Giovanni's style of leadership or strategic thinking without even realizing it. It could also create a great internal conflict for Ash as he discovers his true relation to a rather villainous figure in his world.
Sure. In the Pokémon community, there are numerous fan-created ideas. The idea of Giovanni being Ash's father has some interesting implications. It could potentially change the whole dynamic of Ash's journey. Fanfiction writers often take such unique concepts and run with them, so it's very possible to find such a fanfiction if you search in the right places, like some dedicated Pokémon fanfiction websites.
One common plot point is the revelation of their relationship. Usually, it's a big shock to Ash and the other characters. Another is Giovanni trying to protect Ash secretly while still being the leader of Team Rocket. Sometimes, there are also flashbacks showing how Giovanni might have been involved in Ash's early life in the fanfiction.
A possible plot could be that Giovanni discovers a secret power source that could make his pokemon invincible. Ash gets wind of this and realizes the danger it poses. The battle between them then becomes not just about their personal rivalry but about the fate of all pokemon. Ash may start the battle at a disadvantage but through his unwavering belief in his pokemon and himself, he gradually turns the tables against Giovanni.
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.
Ash might become more conflicted. He has always been on the side of good, but with Giovanni as his father, he'd have to grapple with his family ties. He could become more secretive and brooding as he tries to figure out how to balance his own values with this newfound family connection.
One possible plot development could be Ash's discovery of his true paternity. He might initially be in shock and disbelief. Then, he could struggle with his identity, whether to embrace his connection to Giovanni or to reject it due to Giovanni's often villainous actions. Another aspect could be how his friends in the Pokémon world react to this revelation. Some might be supportive, while others could be suspicious of Ash's motives now that he has this new family tie.
In fanfiction, evidence could be things like Giovanni having a soft spot for Ash that other characters don't notice. The author might write that Giovanni has some knowledge about Ash's past or abilities that seem to suggest a closer relationship. But this is just for the purpose of the fanfiction. In the canonical Pokemon world, Ash's father has not been officially revealed as Giovanni.
Often, it's portrayed as a complex relationship. Since Giovanni is typically seen as a villain in the Pokémon series, the fanfiction might show a struggle between Ash's good - natured self and Giovanni's more self - interested motives. For example, Giovanni might try to manipulate Ash into joining Team Rocket.
Well, a plot twist could be that Giovanni has been secretly watching over Ash all this time, not as an enemy but as a father. Maybe he's been guiding Ash's adventures from the shadows, making sure he becomes strong. And then, when Ash finds out, he has to decide whether to accept Giovanni as his father or reject him because of Giovanni's past actions with Team Rocket.
