Since I don't know this particular story, it could be something very local or specific to a certain community or group. Maybe it's a story about a character named Kuku Mathur who faced some sort of misfortune or downfall, but without more details it's hard to say for sure.
It could be a story of loss. Maybe Kuku Mathur has lost something important like a job, a friendship or a possession. The expression gives the sense of something going wrong, and loss is a common theme in such cases. It could also be about how he copes with this loss, if that's what the story is about.
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 of the top stories could be about Vegeta's intense battles against powerful foes. His fight against Goku is always a significant story. Vegeta constantly tries to prove himself as the strongest, and these battles showcase his growth and determination.
If Vegeta was a girl, it might change the dynamics within the Dragon Ball universe. Her interactions with other characters could be very different, and her power might be perceived differently too.
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.
Vegeta would likely still be his proud and strong - willed self, but with a newfound tenderness towards Bulma. He might be a bit more protective and less quick to anger. Bulma, on the other hand, would be her intelligent and sassy self, always ready to challenge Vegeta in a playful way.
In a fanfic, Naruto might power up by having a spiritual awakening. He could connect with the spirits of past Hokages in a deeper way, gaining their knowledge and some of their power. This could enhance his existing jutsu and give him new abilities. Vegeta could power up if he were to face a near - death experience against Naruto. This could trigger a hidden potential within him, like a new type of Super Saiyan form that has unique abilities. He could also fuse with another Saiyan (if there were another Saiyan available in the fanfic's scenario) to create an even more powerful being.
In DBZ Vegeta and Bulma fanfiction, there can be alternate universes explored. Maybe in one universe, they meet under different circumstances. For instance, instead of Vegeta coming to Earth as an enemy, he could be an ally from the start. This would completely change the dynamics of their relationship. It could lead to a more romantic and less combative start to their relationship, and the fanfiction could explore how this different beginning affects their future together.
Typically, female Vegeta fanfic often focuses on exploring Vegeta's softer side. It might also emphasize relationships, like a romantic relationship between Vegeta and a female character. Another characteristic is that it may give a different perspective on Vegeta's power and his place in the Dragon Ball universe.
