Yes, in the vast world of fanfiction, there are all kinds of creative and out - of - the - box stories. Some fans like to explore unusual relationships and scenarios, so it's possible that there is such a fanfiction out there. However, it goes against the original canon of the Dragon Ball series in many ways.
A 'naruto spirit bomb fanfic' could be centered around the spirit bomb concept borrowed from Dragon Ball. In Naruto's world, it might be a fan - created story where Naruto discovers a new power that is similar to the spirit bomb. This could be due to some sort of cross - dimensional event or an ancient power that was hidden in the Naruto universe all along. It might also be a way to bring together different ninja clans to contribute their energy to create a super - powerful attack.
In such fanfiction, Vegeta might make Bulma happy by showing his softer side. Maybe he cooks a special meal for her. Vegeta is often portrayed as tough, but when he does something out of his usual character like cooking, it can be a sweet surprise for Bulma.
Their relationship would likely become more intimate and committed. With a baby on the way, Vegeta would probably be more protective of Bulma. He might show his love in more practical ways, like making sure she has everything she needs.
Obviously Naruto would be the main character as it's a Naruto - related fanfic. But other characters like Sasuke could also be important. Sasuke might be initially skeptical of Naruto's new spirit bomb - like ability or could even be jealous. Sakura could play a role in helping Naruto master this new power, maybe by using her medical ninjutsu to keep Naruto in top shape during his training.
The plot could involve Vegeta being tricked into drinking a powerful alien beverage. Once drunk, he loses his inhibitions. He might end up getting into a comical fight with Bulma over something silly, like who has the better hair. Then, he could try to fly but end up crashing into a tree. His friends would be both worried and amused as they try to sober him up.
In a 'Vegeta gets Bulma pregnant fanfiction', perhaps it starts with a big event that makes Vegeta realize how much he values Bulma. This leads to them becoming closer and soon Bulma is pregnant. The story could then focus on how Vegeta's Saiyan pride affects his reaction. He might be initially shocked but then become super protective. And Bulma, being the smart and strong - willed woman she is, would be preparing for the baby while also dealing with Vegeta's sometimes over - the - top reactions.
Well, obviously Vegeta is the main character. Bulma would likely be very involved as his partner. Goku might also play a role, perhaps being confused at first but then offering his support.
One possible plotline could be Vegeta dealing with the physical and emotional changes during pregnancy. He might struggle with his pride while also having to rely on others for support.
