It could be that some external events in the fanfiction have caused a rift. For example, perhaps Trunks did something that Vegeta disagreed with strongly. It might be related to Trunks' choice of a different path in training or his association with certain characters that Vegeta doesn't like. In fanfiction, the writers often create these kinds of conflicts to explore different aspects of the characters.
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.
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.
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.
One possible analysis could be that it might explore the complex relationship between Vegeta and Trunks. Maybe in this fanfiction, Vegeta's strict training methods could be seen as 'hurting' Trunks in a sense, like pushing him too hard physically or emotionally. It could also delve into how Trunks copes with that and if it ultimately makes him stronger.
Fanfiction authors often like to experiment with different 'what - if' scenarios. Making Goku Trunks' father could be a way to explore how the story would unfold differently. Maybe they want to see how Goku's influence would shape Trunks' personality in a way that's different from how Vegeta does. It could also be a way to merge different story arcs or character traits that don't usually interact in the original series. For example, combining Goku's pure - hearted nature with Trunks' more serious and future - focused attitude. This can lead to a whole new set of adventures and character developments that are not possible in the official story.
A possible scenario is that Vegeta gets involved in a fight that he knows is dangerous but still pursues it, and as a result, his enemies target Bulma and Trunks. Another is that he may be under some sort of mind control in the fanfiction and end up attacking them unknowingly. Also, his pride - driven actions, like trying to prove himself as the strongest, could lead to situations where Bulma and Trunks are put at risk, for example, if he challenges a much stronger opponent near their home.
It could be that the character has found someone else who shows more care and attention. In fanfics, new characters can be introduced who are more in tune with the main character's emotional needs. Unlike Vegeta, who may be seen as too cold or unresponsive.
Well, family is a big one. Vegeta's love for Trunks is often explored in the context of family bonds, which is different from his relationships with others. Protection is also common. Vegeta will do anything to keep Trunks safe. And there's the theme of legacy, with Vegeta wanting Trunks to carry on the Saiyan pride and power in a proper way.
Sure. There are quite a few. Some focus on Vegeta's pride in Trunks and how he shows his love in his own gruff way. For example, there are stories where Vegeta secretly trains Trunks extra hard because he wants him to be strong. Others might explore how Trunks looks up to Vegeta, and how that admiration is reciprocated in Vegeta's love for his son.
It could be that Vegeta is influenced by some external force or an old Saiyan belief that makes him act in a way that hurts Trunks. Maybe he believes that only through extreme hardship can Trunks reach his true potential. So he subjects Trunks to dangerous situations or withholds his affection. As the fanfiction progresses, Trunks could start to rebel against Vegeta's ways, and they would have to navigate through their differences and find a middle ground.
Another plot could be that the character who says this has met someone else who shows them a different kind of love and attention. They start comparing this new person to Vegeta and realize that they are no longer in love with Vegeta. This new relationship makes them see all the flaws in their relationship with Vegeta that they were previously overlooking.
