Goku should have married Bulma for a couple of reasons which would be listed below.
On the off chance that Goku would have hitched Bulma he could have opened SSJ and different changes speedier than appeared in the Manga/Anime. In both of these it is demonstrated that Bulma couldn’t care less if Vegeta is preparing which he is practically continually doing. Now and again Bulma even makes preparing hardware for Vegeta to wind up noticeably more grounded, for instance the simulated gravity room. For some obscure reason Goku is constantly in front of Vegeta in preparing despite the fact that Vegeta is continually giving preparing his everything, and Bulma isn’t a snag. Envision Goku being permitted to prepare at whatever point he feels like itand having no hindrances like Chichi . This practically make him strong.
On the off chance that Gohan was Bulma’s child she wouldn’t have constrained him to be a researcher and to examine as opposed to preparing. Additionally if Gohan hadn’t been compelled to be a researcher he could have been one of the most grounded DBZ characters at this moment on the grounds that amid the Cell Games he opened SSJ2. On the off chance that he continued preparing he could have even been SSJ3 on the off chance that he didn’t needed to go to class as a result of Chichi.
In the event that Goku would have been permitted to prepare at whatever point he needs a considerable measure of lifes would have been spared all through the whole arrangement in light of the fact that Goku would dependably have the high ground.
Doing this would have detracted from the energy of seeing our legend Goku being pounded the life out of practically and all of a sudden accomplishing a more prominent energy to crush that adversary.
Which clarifies why Goku didn’t wedded Bulma. In one a player in the arrangement Bulma was appeared as making them feel for Goku.
She felt for goku many times in dragon ball :
In this photo Bulma is indicated considering how great looking Goku has moved toward becoming since they met.
In any case, I figure Akira Toriyama would not like to detract from this fervor of accomplishing new change, so nothing really occurred amongst Goku and Bulma.
