There is a theory that Bulma asked the Divine Dragon to grant a wish and it indirectly led to the Saiyan invasion of Earth.
Saiyan Saga is one of the biggest arcs in the Dragon Ball series. It explains Goku’s Saiyan origin, kills several important characters, and catalyzes the trip to planet Namek, thus leading to some of the events of the Namek Saga and everything that follows. However, one of its biggest influences was the appearance of Vegeta, Goku’s arch-rival.
Another important thing about Vegeta is that he is Bulma’s husband now. Putting aside their differences, they seem to be living a happy life with two children. This makes many people think that even though Saiyan Saga has many difficulties and fierceness, it is not completely a bad thing because it has brought a beautiful love story in Dragon Ball .
However, when thinking about this, some fans realized that it was possible that Bulma herself indirectly created it. Specifically, Bulma had many times wished to find a perfect and better boyfriend than Yamcha. Hypothetically, Bulma could have used the time between Dragon Ball and Dragon Ball Z to collect the dragon balls and summon Shenron, then ask for this wish. However, instead of directly granting this wish immediately, Shenron “controlled” it. events that led to Vegeta arriving on Earth and finally meeting Bulma.
This is probably not a baseless theory, as we also know there is a 5 year gap between Dragon Ball and Dragon Ball Z, it is enough time for anyone to do it if they want to earn dragon balls to fulfill their wishes, especially is Bulma. She is the first person to appear in the series, wanting to find the magical dragon to bring her a good boyfriend.
But after meeting Yamacha, she felt that she no longer needed to ask the dragon god. However, when she was fed up with him always being on the baseball field, she would naturally want to find someone else to replace him. With all this in mind, we can believe that Bulma used the Dragon Balls to wish for a new, better boyfriend. And it caused Vegeta to appear and the Earth to fall into danger of the Saiyans.
