For the other Saiyans in the story, if there are any, they might view Vegeta differently. They could see his lack of love for Trunks as a sign of weakness or a strange Saiyan behavior. This might lead to some internal conflicts within the Saiyan community in the fanfiction. Some might side with Vegeta, believing he has his reasons, while others might condemn him for not fulfilling his fatherly duties.
Gohan might try to be a better friend to Trunks. With Vegeta's change, Gohan, who has always been a good - hearted character, may step in to support Trunks. He could offer his own training methods or just be there as an emotional support. This would strengthen their friendship and might also create an interesting dynamic between Gohan and Vegeta, as Vegeta might see this as an intrusion or a sign of weakness on Trunks' part.
Maybe in the fanfiction, Vegeta has some personal growth that makes him focus more on himself rather than family. He might have new goals and ambitions that he thinks are more important than his relationship with Trunks.
The relationship could develop in a more emotional way. Maybe Trunks gets injured badly in a fight, and Vegeta realizes how much he cares for his son. He then becomes more protective and affectionate towards Trunks. On the other hand, Trunks could also start to understand his father better, seeing that Vegeta's tough love is actually a way of showing his love and concern. This new understanding could lead to a more harmonious and loving relationship between them.
They could become more like colleagues or just friends from the past. There's no longer the romantic tension between them. Sakura might have to come to terms with the fact that Naruto's feelings have changed and try to move on as well. Naruto, on the other hand, may focus more on his other relationships, like with his new friends or teammates.
Well, it might make the Cullens more protective of Renesmee. If she doesn't love Jacob, they may see him as a potential threat to her emotional well - being, and be more cautious around him. For example, Edward might be more vigilant in keeping Jacob at a distance.
His relationship with the professors could be very different. Some professors like McGonagall might be intrigued and want to study this new form of magic. Others, like Snape, might be more suspicious and think Harry is up to some new form of mischief or dark magic. This would create a whole new dynamic in the Hogwarts environment.
Fanfiction can explore their relationship by looking at their cultural differences. Vegeta is a Saiyan from a warrior race, while Bulma is a human scientist. Baby Trunks is a mix of both. So, a story could be about how they teach Trunks about his dual heritage, like Vegeta teaching him about Saiyan pride and Bulma teaching him about human values like kindness and curiosity.
It changes the way they interact with their friends too. Their mutual friends might have to choose sides or try to mediate. And it also affects their group dynamic in battles or quests. For example, they might not be as coordinated as before, which could put them in more danger.
In their story, Vegeta is Kid Trunks' father. Vegeta is a Saiyan prince, and his relationship with Kid Trunks is complex. He has high expectations for Trunks and at times can be strict, but deep down he cares about his son's growth and development as a Saiyan warrior.
The relationship might develop gradually. Bulma could start by being attracted to Vegeta's power and mystery. As she gets closer to him, she discovers his more complex personality. Vegeta may initially resist her advances but eventually gives in to his own feelings.
The fanfiction might make their relationship more equal in a different sense. Before, there was always a bit of a power struggle between them. But as mates, they have to respect each other on a whole new level. They would have to consider each other's feelings and opinions more. For example, when making decisions about how to face a new enemy, they would have to consult each other rather than just going with their own instincts like they used to.
