In many fanfictions, Vegeta starts as an outsider. He's a Saiyan in a world full of mages. His initial development is about adapting. He has to learn the rules of the Fairy Tail world. For instance, he might not understand the concept of magic guilds at first. As he spends more time there, he becomes more open - minded. He starts to see the value in the friendships and teamwork that are so important in Fairy Tail.
One interesting 'Vegeta Fairy Tail' fanfiction could be where Vegeta from Dragon Ball somehow gets transported to the Fairy Tail universe. He might start off as a powerful and mysterious figure. Maybe he teams up with Natsu and they have this epic battle against a powerful dark wizard. His Saiyan strength and combat skills would add a whole new dynamic to the Fairy Tail world.
Often, Vegeta becomes more in touch with his emotions. He starts to care about things other than just fighting, like his family with Bulma. He may show more love and protectiveness towards her and their child.
Naruto's character would become more disciplined. Vegeta is a strict trainer, so Naruto would have to follow a more rigid routine. This could make him less impulsive.
In some fanfictions, she might start as a naive character but develop into a strong and independent one. For example, she could initially be in Zeref's shadow but then realize her own worth and power.
He could also become more strategic. Time travel would expose him to different situations and enemies. He'd need to plan better and think ahead. Maybe he travels to a time when the Z - fighters are all defeated, and he has to figure out how to prevent it. This would make him less impulsive and more of a long - term thinker.
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.
At first, it might be a relationship based on mutual need. Vegeta needs Bulma's resources and intelligence to get back on his feet, and Bulma is intrigued by this alien. As time passes, they start to understand each other better. For example, Vegeta may start to open up about his past and his Saiyan pride, and Bulma will share her dreams and ambitions with him.
Bardock may start as a typical Saiyan, focused mainly on fighting and power. But as he faces the threat to Planet Vegeta, he could start to develop a sense of responsibility. He realizes that there's more at stake than just his own glory in battle.
It often starts with a shock or surprise at the mpreg situation. Then, they gradually learn to rely on each other more. For example, Vegeta might start to show a more caring side that he usually hides, and Goku might become more responsible. They'll have to communicate more, sharing their fears and hopes about the future with the baby.
In fanfiction, their relationship can develop through shared battles. For example, when they both face a common enemy stronger than either of them alone. They start to communicate and strategize, and in the process, they see each other in a new light.
