One potential theme could be family. Vegeta's relationship with his son is explored, showing how a Saiyan warrior like him can adapt to fatherhood. Another theme might be growth, as Baby Trunks learns from Vegeta and Vegeta also grows as a person through this new connection.
Well, it could be that Vegeta, upon meeting Baby Trunks, realizes the importance of family in a new way. He might start to see the future differently, knowing that he has a son to protect and guide. There could also be some cute moments where Baby Trunks tries to imitate Vegeta's tough guy expressions, which would be quite endearing.
A really cool fanfiction could be set in an alternate universe where Vegeta and Baby Trunks switch bodies for a day. This would lead to all sorts of hilarious and heart - warming situations as they try to understand each other's lives better. Vegeta would see how difficult it is for Trunks to be in his shadow, and Trunks would understand his father's strictness a bit more.
One interesting fanfiction could be about Vegeta training Baby Trunks in a new and unique way. Maybe he takes him to a far - off planet with strange gravitational forces to toughen him up.
Their relationships are often shown as loving yet complex. Vegeta, who was once a cold - hearted warrior, has a soft spot for his family. He is protective of Bulma and Baby Trunks. Bulma is the brains of the family, and she manages to keep Vegeta in check. Baby Trunks is the source of joy and also a reason for Vegeta to strive to be a better person.
You can start by looking on popular fanfiction websites like FanFiction.net or Archive of Our Own. These platforms have a wide range of fan - created stories, and you can easily search for Vegeta and Baby Trunks - related fanfiction using their search bars.
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.
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.
A fanfiction could focus on a day in the life of the family. Bulma could be working on some new invention in her lab, Vegeta is training hard outside, and Baby Trunks is getting into all sorts of cute mischief. Then, something unexpected like a small alien invasion occurs near their home, and they all have to work together to deal with it.
There's a fanfiction where Vegeta is seriously injured in a battle. Baby Trunks refuses to leave his side and tries to heal him with his own ki. It's a very touching story that shows the deep love and bond between them.
