His father might be extremely proud. After all, Goku has achieved so much, like protecting the Earth multiple times. He would look at Goku with admiration for his strength and kindness.
It gives fans a chance to explore different 'what - if' scenarios. By seeing the Avengers' reactions, fans can get a deeper understanding of the characters.
It can contribute by adding new storylines. The Dragon Ball series has a huge universe, and fanfiction like this expands it further. It gives fans something new to explore and discuss. For instance, fans can debate about the plausibility of a relationship between Goku and Female Broly, which keeps the fandom active.
It's a rather controversial genre. In the original Dragon Ball series, Goku and Pan have a family - like relationship, so a romantic or 'forbidden love' concept goes against the intended family dynamic. However, in the realm of fanfiction, different interpretations exist, but it may make many traditional fans uncomfortable.
Some fans might be disappointed. Fanfiction often allows them to explore different scenarios with Naruto's character. If he gives it up, it's like closing a door on those creative possibilities.
Gohan would be really surprised, but being the kind - hearted person he is, he would try to understand and help out. He could offer to train with them in a more gentle way to keep them fit during the pregnancy. Piccolo would be more of a silent observer, but still be there in case of any threats.
The reaction among fans would be quite mixed. Some die - hard fans of the original series would be appalled as they have a clear image of ChiChi and Goku's relationship. They would see this type of fanfiction as a perversion of the original concept. On the other hand, there are those who are more open - minded and might see it as an interesting, if not controversial, exploration of the characters. But overall, the negative reactions would probably outweigh the positive ones.
Goku would be a mix of angry and worried. His Saiyan blood would make him want to rush into battle with Raditz right away. But he also knows how dangerous Raditz is, so he might first try to gather some allies, like Piccolo. He'd be constantly thinking about Gohan and how to rescue him as quickly as possible.
Yes, it is quite popular in some corners of the Dragon Ball fandom. There are many fans who enjoy exploring different relationship dynamics between the characters, and the idea of Vegeta and Goku falling in love offers a unique and often interesting take on their relationship. It allows for creative interpretations of their personalities and how they might interact in a romantic context.
